use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||

|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||

|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.

unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||

|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||

|
||||
## Getting the Engine
|
||||
|
||||
### Using npm
|
||||
|
||||
```bash
|
||||
npm install @esengine/ecs-framework
|
||||
```
|
||||
|
||||
## 快速开始
|
||||
### Building from Source
|
||||
|
||||
### 基础设置
|
||||
See [Building from Source](#building-from-source) for detailed instructions.
|
||||
|
||||
### Editor Download
|
||||
|
||||
Pre-built editor binaries are available on the [Releases](https://github.com/esengine/ecs-framework/releases) page for Windows and macOS.
|
||||
|
||||
## Quick Start
|
||||
|
||||
```typescript
|
||||
import { Core, Scene, Entity, Component, EntitySystem } from '@esengine/ecs-framework';
|
||||
import {
|
||||
Core, Scene, Entity, Component, EntitySystem,
|
||||
Matcher, Time, ECSComponent, ECSSystem
|
||||
} from '@esengine/ecs-framework';
|
||||
|
||||
// 创建核心实例 - 使用配置对象(推荐)
|
||||
const core = Core.create({
|
||||
debug: true, // 启用调试模式
|
||||
enableEntitySystems: true, // 启用实体系统
|
||||
debugConfig: { // 可选:调试配置
|
||||
enabled: true,
|
||||
websocketUrl: 'ws://localhost:8080',
|
||||
autoReconnect: true,
|
||||
updateInterval: 1000,
|
||||
channels: {
|
||||
entities: true,
|
||||
systems: true,
|
||||
performance: true,
|
||||
components: true,
|
||||
scenes: true
|
||||
}
|
||||
}
|
||||
});
|
||||
|
||||
// 简化创建 - 向后兼容(仍然支持)
|
||||
const core2 = Core.create(true); // 等同于 { debug: true, enableEntitySystems: true }
|
||||
|
||||
// 创建场景
|
||||
const scene = new Scene();
|
||||
Core.scene = scene;
|
||||
```
|
||||
|
||||
### 定义组件
|
||||
|
||||
```typescript
|
||||
class PositionComponent extends Component {
|
||||
constructor(public x: number = 0, public y: number = 0) {
|
||||
super();
|
||||
}
|
||||
@ECSComponent('Position')
|
||||
class Position extends Component {
|
||||
x = 0;
|
||||
y = 0;
|
||||
}
|
||||
|
||||
class VelocityComponent extends Component {
|
||||
constructor(public dx: number = 0, public dy: number = 0) {
|
||||
super();
|
||||
}
|
||||
@ECSComponent('Velocity')
|
||||
class Velocity extends Component {
|
||||
dx = 0;
|
||||
dy = 0;
|
||||
}
|
||||
|
||||
class HealthComponent extends Component {
|
||||
constructor(
|
||||
public maxHealth: number = 100,
|
||||
public currentHealth: number = 100
|
||||
) {
|
||||
super();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 创建实体
|
||||
|
||||
```typescript
|
||||
// 基础实体创建
|
||||
const player = scene.createEntity("Player");
|
||||
player.addComponent(new PositionComponent(100, 100));
|
||||
player.addComponent(new VelocityComponent(5, 0));
|
||||
player.addComponent(new HealthComponent(100, 100));
|
||||
|
||||
// 批量创建实体
|
||||
const enemies = scene.createEntities(50, "Enemy");
|
||||
```
|
||||
|
||||
### 创建系统
|
||||
|
||||
```typescript
|
||||
@ECSSystem('Movement')
|
||||
class MovementSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super();
|
||||
super(Matcher.all(Position, Velocity));
|
||||
}
|
||||
|
||||
public process(entities: Entity[]) {
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const position = entity.getComponent(PositionComponent);
|
||||
const velocity = entity.getComponent(VelocityComponent);
|
||||
|
||||
if (position && velocity) {
|
||||
position.x += velocity.dx;
|
||||
position.y += velocity.dy;
|
||||
}
|
||||
const pos = entity.getComponent(Position);
|
||||
const vel = entity.getComponent(Velocity);
|
||||
pos.x += vel.dx * Time.deltaTime;
|
||||
pos.y += vel.dy * Time.deltaTime;
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// 添加系统到场景
|
||||
scene.addEntityProcessor(new MovementSystem());
|
||||
```
|
||||
Core.create();
|
||||
const scene = new Scene();
|
||||
scene.addSystem(new MovementSystem());
|
||||
|
||||
### 游戏循环
|
||||
const player = scene.createEntity('Player');
|
||||
player.addComponent(new Position());
|
||||
player.addComponent(new Velocity());
|
||||
|
||||
ECS框架需要在游戏引擎的更新循环中调用:
|
||||
Core.setScene(scene);
|
||||
|
||||
```typescript
|
||||
// 统一的API:传入deltaTime
|
||||
Core.update(deltaTime);
|
||||
```
|
||||
|
||||
**不同平台的集成示例:**
|
||||
|
||||
```typescript
|
||||
// Laya引擎
|
||||
Laya.timer.frameLoop(1, this, () => {
|
||||
const deltaTime = Laya.timer.delta / 1000; // 转换为秒
|
||||
Core.update(deltaTime);
|
||||
});
|
||||
|
||||
// Cocos Creator
|
||||
update(deltaTime: number) {
|
||||
Core.update(deltaTime);
|
||||
}
|
||||
|
||||
// 原生浏览器环境
|
||||
// Game loop
|
||||
let lastTime = 0;
|
||||
function gameLoop(currentTime: number) {
|
||||
const deltaTime = lastTime > 0 ? (currentTime - lastTime) / 1000 : 0.016;
|
||||
const deltaTime = (currentTime - lastTime) / 1000;
|
||||
lastTime = currentTime;
|
||||
|
||||
Core.update(deltaTime);
|
||||
requestAnimationFrame(gameLoop);
|
||||
}
|
||||
requestAnimationFrame(gameLoop);
|
||||
```
|
||||
|
||||

使用装饰器语法自动注册事件监听器,减少样板代码。
|
||||
|
||||
```typescript
|
||||
import { EventHandler, ECSEventType } from '@esengine/ecs-framework';
|
||||
|
||||
class GameSystem {
|
||||
@EventHandler(ECSEventType.ENTITY_DESTROYED)
|
||||
onEntityDestroyed(data: EntityDestroyedEventData) {
|
||||
console.log('实体销毁:', data.entityName);
|
||||
}
|
||||
|
||||
@EventHandler('player:levelup')
|
||||
onPlayerLevelUp(data: { playerId: number; newLevel: number }) {
|
||||
console.log(`玩家 ${data.playerId} 升级到 ${data.newLevel} 级`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 性能优化
|
||||
|
||||
### [组件索引](docs/concepts-explained.md#组件索引系统)
|
||||
|
||||
通过建立索引避免线性搜索,将查询复杂度从 O(n) 降低到 O(1)。
|
||||
|
||||
```typescript
|
||||
// 使用Scene的查询系统进行组件索引
|
||||
const querySystem = scene.querySystem;
|
||||
|
||||
// 查询具有特定组件的实体
|
||||
const entitiesWithPosition = querySystem.queryAll(PositionComponent).entities;
|
||||
const entitiesWithVelocity = querySystem.queryAll(VelocityComponent).entities;
|
||||
|
||||
// 性能统计
|
||||
const stats = querySystem.getStats();
|
||||
console.log('查询效率:', stats.hitRate);
|
||||
```
|
||||
|
||||
**索引类型选择:**
|
||||
- **哈希索引** - 适合稳定的、大量的组件(如位置、生命值)
|
||||
- **位图索引** - 适合频繁变化的组件(如Buff、状态)
|
||||
|
||||
> 📋 详细选择指南参见 [索引类型选择指南](docs/concepts-explained.md#索引类型选择指南)
|
||||
|
||||
### [Archetype 系统](docs/concepts-explained.md#archetype-系统)
|
||||
|
||||
将具有相同组件组合的实体分组,减少查询时的组件检查开销。
|
||||
|
||||
```typescript
|
||||
// 使用查询系统的Archetype功能
|
||||
const querySystem = scene.querySystem;
|
||||
|
||||
// 查询统计
|
||||
const stats = querySystem.getStats();
|
||||
console.log('缓存命中率:', stats.hitRate);
|
||||
```
|
||||
|
||||
### [脏标记系统](docs/concepts-explained.md#脏标记系统)
|
||||
|
||||
追踪数据变化,只处理发生改变的实体,避免不必要的计算。
|
||||
|
||||
```typescript
|
||||
// 脏标记通过组件系统自动管理
|
||||
// 组件变化时会自动标记为脏数据
|
||||
|
||||
// 查询系统会自动处理脏标记优化
|
||||
const movingEntities = scene.querySystem.queryAll(PositionComponent, VelocityComponent);
|
||||
```

||||

```typescript
|
||||
import {
|
||||
Core, Scene, Entity, Component, EntitySystem,
|
||||
Matcher, Time, ECSComponent, ECSSystem
|
||||
} from '@esengine/ecs-framework';
|
||||
|
||||
@ECSComponent('Position')
|
||||
class Position extends Component {
|
||||
x = 0;
|
||||
y = 0;
|
||||
}
|
||||
|
||||
@ECSComponent('Velocity')
|
||||
class Velocity extends Component {
|
||||
dx = 0;
|
||||
dy = 0;
|
||||
}
|
||||
|
||||
@ECSSystem('Movement')
|
||||
class MovementSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(Position, Velocity));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const pos = entity.getComponent(Position);
|
||||
const vel = entity.getComponent(Velocity);
|
||||
pos.x += vel.dx * Time.deltaTime;
|
||||
pos.y += vel.dy * Time.deltaTime;
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
Core.create();
|
||||
const scene = new Scene();
|
||||
scene.addSystem(new MovementSystem());
|
||||
|
||||
const player = scene.createEntity('Player');
|
||||
player.addComponent(new Position());
|
||||
player.addComponent(new Velocity());
|
||||
|
||||
Core.setScene(scene);
|
||||
|
||||
// 游戏循环
|
||||
let lastTime = 0;
|
||||
function gameLoop(currentTime: number) {
|
||||
const deltaTime = (currentTime - lastTime) / 1000;
|
||||
lastTime = currentTime;
|
||||
|
||||
Core.update(deltaTime);

# 位掩码使用指南
|
||||

|
||||
6. [性能优化技巧](#性能优化技巧)
|
||||
|
||||
## 什么是位掩码
|
||||
|
||||
### 基本概念
|
||||
|
||||
位掩码(BitMask)是一种使用二进制位来表示状态或属性的技术。在ECS框架中,每个组件类型对应一个二进制位,实体的组件组合可以用一个数字来表示。
|
||||
|
||||
### 简单例子
|
||||
|
||||
假设我们有以下组件:
|
||||
- PositionComponent → 位置 0 (二进制: 001)
|
||||
- VelocityComponent → 位置 1 (二进制: 010)
|
||||
- HealthComponent → 位置 2 (二进制: 100)
|
||||
|
||||
那么一个同时拥有Position和Health组件的实体,其位掩码就是:
|
||||
```
|
||||
001 (Position) + 100 (Health) = 101 (二进制) = 5 (十进制)
|
||||
```
|
||||
|
||||
### 可视化理解
|
||||
|
||||
```typescript
|
||||
// 组件类型对应的位位置
|
||||
PositionComponent → 位置0 → 2^0 = 1 → 二进制: 001
|
||||
VelocityComponent → 位置1 → 2^1 = 2 → 二进制: 010
|
||||
HealthComponent → 位置2 → 2^2 = 4 → 二进制: 100
|
||||
RenderComponent → 位置3 → 2^3 = 8 → 二进制: 1000
|
||||
|
||||
// 实体的组件组合示例
|
||||
实体A: Position + Velocity → 001 + 010 = 011 (二进制) = 3 (十进制)
|
||||
实体B: Position + Health → 001 + 100 = 101 (二进制) = 5 (十进制)
|
||||
实体C: Position + Velocity + Health → 001 + 010 + 100 = 111 (二进制) = 7 (十进制)
|
||||
```
|
||||
|
||||
## 位掩码的优势
|
||||
|
||||
### 1. 极快的查询速度
|
||||
|
||||
```typescript
|
||||
// 传统方式:需要遍历组件列表
|
||||
function hasComponents(entity, componentTypes) {
|
||||
for (const type of componentTypes) {
|
||||
if (!entity.hasComponent(type)) {
|
||||
return false;
|
||||
}
|
||||
}
|
||||
return true;
|
||||
}
|
||||
|
||||
// 位掩码方式:一次位运算即可
|
||||
function hasComponentsMask(entityMask, requiredMask) {
|
||||
return (entityMask & requiredMask) === requiredMask;
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 内存效率
|
||||
|
||||
```typescript
|
||||
// 一个bigint可以表示64个组件的组合状态
|
||||
// 相比存储组件列表,内存使用量大大减少
|
||||
|
||||
const entity = scene.createEntity("Player");
|
||||
entity.addComponent(new PositionComponent());
|
||||
entity.addComponent(new HealthComponent());
|
||||
|
||||
// 获取位掩码(只是一个数字)
|
||||
const mask = entity.componentMask; // bigint类型
|
||||
console.log(`位掩码: ${mask}`); // 输出: 5 (二进制: 101)
|
||||
```
|
||||
|
||||
### 3. 批量操作优化
|
||||
|
||||
```typescript
|
||||
// 可以快速筛选大量实体
|
||||
const entities = scene.getAllEntities();
|
||||
const requiredMask = BigInt(0b101); // Position + Health
|
||||
|
||||
const filteredEntities = entities.filter(entity =>
|
||||
(entity.componentMask & requiredMask) === requiredMask
|
||||
);
|
||||
```
|
||||
|
||||
## 基础使用方法
|
||||
|
||||
### 获取实体的位掩码
|
||||
|
||||
```typescript
|
||||
import { Scene, Entity, Component } from '@esengine/ecs-framework';
|
||||
|
||||
// 创建组件
|
||||
class PositionComponent extends Component {
|
||||
constructor(public x: number = 0, public y: number = 0) {
|
||||
super();
|
||||
}
|
||||
}
|
||||
|
||||
class HealthComponent extends Component {
|
||||
constructor(public maxHealth: number = 100) {
|
||||
super();
|
||||
}
|
||||
}
|
||||
|
||||
// 创建实体并添加组件
|
||||
const scene = new Scene();
|
||||
const entity = scene.createEntity("Player");
|
||||
|
||||
console.log(`初始位掩码: ${entity.componentMask}`); // 0
|
||||
|
||||
entity.addComponent(new PositionComponent(100, 200));
|
||||
console.log(`添加Position后: ${entity.componentMask}`); // 可能是 1
|
||||
|
||||
entity.addComponent(new HealthComponent(100));
|
||||
console.log(`添加Health后: ${entity.componentMask}`); // 可能是 5
|
||||
|
||||
// 查看二进制表示
|
||||
console.log(`二进制表示: ${entity.componentMask.toString(2)}`);
|
||||
```
|
||||
|
||||
### 手动检查位掩码
|
||||
|
||||
```typescript
|
||||
// 检查实体是否拥有特定组件组合
|
||||
function checkEntityComponents(entity: Entity) {
|
||||
const mask = entity.componentMask;
|
||||
|
||||
// 将位掩码转换为二进制字符串查看
|
||||
const binaryString = mask.toString(2).padStart(8, '0');
|
||||
console.log(`实体组件状态: ${binaryString}`);
|
||||
|
||||
// 分析每一位
|
||||
console.log(`位0 (Position): ${(mask & 1n) !== 0n ? '有' : '无'}`);
|
||||
console.log(`位1 (Velocity): ${(mask & 2n) !== 0n ? '有' : '无'}`);
|
||||
console.log(`位2 (Health): ${(mask & 4n) !== 0n ? '有' : '无'}`);
|
||||
console.log(`位3 (Render): ${(mask & 8n) !== 0n ? '有' : '无'}`);
|
||||
}
|
||||
```
|
||||
|
||||
## 高级位掩码操作
|
||||
|
||||
### 使用BitMaskOptimizer
|
||||
|
||||
框架提供了BitMaskOptimizer类来简化位掩码操作:
|
||||
|
||||
```typescript
|
||||
import { BitMaskOptimizer } from '@esengine/ecs-framework';
|
||||
|
||||
// 获取优化器实例
|
||||
const optimizer = BitMaskOptimizer.getInstance();
|
||||
|
||||
// 注册组件类型(建议在游戏初始化时进行)
|
||||
optimizer.registerComponentType('PositionComponent');
|
||||
optimizer.registerComponentType('VelocityComponent');
|
||||
optimizer.registerComponentType('HealthComponent');
|
||||
optimizer.registerComponentType('RenderComponent');
|
||||
|
||||
// 创建单个组件的掩码
|
||||
const positionMask = optimizer.createSingleComponentMask('PositionComponent');
|
||||
console.log(`Position掩码: ${positionMask} (二进制: ${positionMask.toString(2)})`);
|
||||
|
||||
// 创建组合掩码
|
||||
const movementMask = optimizer.createCombinedMask(['PositionComponent', 'VelocityComponent']);
|
||||
console.log(`Movement掩码: ${movementMask} (二进制: ${movementMask.toString(2)})`);
|
||||
|
||||
// 检查实体是否匹配掩码
|
||||
const entity = scene.createEntity("TestEntity");
|
||||
entity.addComponent(new PositionComponent());
|
||||
entity.addComponent(new VelocityComponent());
|
||||
|
||||
const hasMovementComponents = optimizer.maskContainsAllComponents(
|
||||
entity.componentMask,
|
||||
['PositionComponent', 'VelocityComponent']
|
||||
);
|
||||
console.log(`实体拥有移动组件: ${hasMovementComponents}`);
|
||||
```
|
||||
|
||||
### 位掩码分析工具
|
||||
|
||||
```typescript
|
||||
// 分析位掩码的实用函数
|
||||
class MaskAnalyzer {
|
||||
private optimizer = BitMaskOptimizer.getInstance();
|
||||
|
||||
// 分析实体的组件组合
|
||||
analyzeEntity(entity: Entity): void {
|
||||
const mask = entity.componentMask;
|
||||
const componentNames = this.optimizer.maskToComponentNames(mask);
|
||||
const componentCount = this.optimizer.getComponentCount(mask);
|
||||
|
||||
console.log(`实体 ${entity.name} 分析:`);
|
||||
console.log(`- 位掩码: ${mask} (二进制: ${mask.toString(2)})`);
|
||||
console.log(`- 组件数量: ${componentCount}`);
|
||||
console.log(`- 组件列表: ${componentNames.join(', ')}`);
|
||||
}
|
||||
|
||||
// 比较两个实体的组件差异
|
||||
compareEntities(entityA: Entity, entityB: Entity): void {
|
||||
const maskA = entityA.componentMask;
|
||||
const maskB = entityB.componentMask;
|
||||
|
||||
const commonMask = maskA & maskB;
|
||||
const onlyInA = maskA & ~maskB;
|
||||
const onlyInB = maskB & ~maskA;
|
||||
|
||||
console.log(`实体比较:`);
|
||||
console.log(`- 共同组件: ${this.optimizer.maskToComponentNames(commonMask).join(', ')}`);
|
||||
console.log(`- 仅在A中: ${this.optimizer.maskToComponentNames(onlyInA).join(', ')}`);
|
||||
console.log(`- 仅在B中: ${this.optimizer.maskToComponentNames(onlyInB).join(', ')}`);
|
||||
}
|
||||
|
||||
// 查找具有特定组件组合的实体
|
||||
findEntitiesWithMask(entities: Entity[], requiredComponents: string[]): Entity[] {
|
||||
const requiredMask = this.optimizer.createCombinedMask(requiredComponents);
|
||||
|
||||
return entities.filter(entity =>
|
||||
(entity.componentMask & requiredMask) === requiredMask
|
||||
);
|
||||
}
|
||||
}
|
||||
|
||||
// 使用示例
|
||||
const analyzer = new MaskAnalyzer();
|
||||
analyzer.analyzeEntity(entity);
|
||||
```
|
||||
|
||||
## 实际应用场景
|
||||
|
||||
### 1. 高性能实体查询
|
||||
|
||||
```typescript
|
||||
class GameSystem {
|
||||
private optimizer = BitMaskOptimizer.getInstance();
|
||||
private movementMask: bigint;
|
||||
private combatMask: bigint;
|
||||
|
||||
constructor() {
|
||||
// 预计算常用掩码
|
||||
this.movementMask = this.optimizer.createCombinedMask([
|
||||
'PositionComponent', 'VelocityComponent'
|
||||
]);
|
||||
|
||||
this.combatMask = this.optimizer.createCombinedMask([
|
||||
'PositionComponent', 'HealthComponent', 'WeaponComponent'
|
||||
]);
|
||||
}
|
||||
|
||||
// 快速查找移动实体
|
||||
findMovingEntities(entities: Entity[]): Entity[] {
|
||||
return entities.filter(entity =>
|
||||
(entity.componentMask & this.movementMask) === this.movementMask
|
||||
);
|
||||
}
|
||||
|
||||
// 快速查找战斗单位
|
||||
findCombatUnits(entities: Entity[]): Entity[] {
|
||||
return entities.filter(entity =>
|
||||
(entity.componentMask & this.combatMask) === this.combatMask
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 实体分类和管理
|
||||
|
||||
```typescript
|
||||
class EntityClassifier {
|
||||
private optimizer = BitMaskOptimizer.getInstance();
|
||||
|
||||
// 定义实体类型掩码
|
||||
private readonly ENTITY_TYPES = {
|
||||
PLAYER: this.optimizer.createCombinedMask([
|
||||
'PositionComponent', 'HealthComponent', 'InputComponent'
|
||||
]),
|
||||
ENEMY: this.optimizer.createCombinedMask([
|
||||
'PositionComponent', 'HealthComponent', 'AIComponent'
|
||||
]),
|
||||
PROJECTILE: this.optimizer.createCombinedMask([
|
||||
'PositionComponent', 'VelocityComponent', 'DamageComponent'
|
||||
]),
|
||||
PICKUP: this.optimizer.createCombinedMask([
|
||||
'PositionComponent', 'PickupComponent'
|
||||
])
|
||||
};
|
||||
|
||||
// 根据组件组合判断实体类型
|
||||
classifyEntity(entity: Entity): string {
|
||||
const mask = entity.componentMask;
|
||||
|
||||
for (const [type, typeMask] of Object.entries(this.ENTITY_TYPES)) {
|
||||
if ((mask & typeMask) === typeMask) {
|
||||
return type;
|
||||
}
|
||||
}
|
||||
|
||||
return 'UNKNOWN';
|
||||
}
|
||||
|
||||
// 批量分类实体
|
||||
classifyEntities(entities: Entity[]): Map<string, Entity[]> {
|
||||
const classified = new Map<string, Entity[]>();
|
||||
|
||||
for (const entity of entities) {
|
||||
const type = this.classifyEntity(entity);
|
||||
if (!classified.has(type)) {
|
||||
classified.set(type, []);
|
||||
}
|
||||
classified.get(type)!.push(entity);
|
||||
}
|
||||
|
||||
return classified;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 性能优化技巧
|
||||
|
||||
### 1. 预计算常用掩码
|
||||
|
||||
```typescript
|
||||
class MaskCache {
|
||||
private optimizer = BitMaskOptimizer.getInstance();
|
||||
|
||||
// 预计算游戏中常用的组件组合
|
||||
public readonly COMMON_MASKS = {
|
||||
RENDERABLE: this.optimizer.createCombinedMask([
|
||||
'PositionComponent', 'RenderComponent'
|
||||
]),
|
||||
MOVABLE: this.optimizer.createCombinedMask([
|
||||
'PositionComponent', 'VelocityComponent'
|
||||
]),
|
||||
LIVING: this.optimizer.createCombinedMask([
|
||||
'HealthComponent'
|
||||
]),
|
||||
INTERACTIVE: this.optimizer.createCombinedMask([
|
||||
'PositionComponent', 'ColliderComponent'
|
||||
])
|
||||
};
|
||||
|
||||
constructor() {
|
||||
// 预计算常用组合以提升性能
|
||||
this.optimizer.precomputeCommonMasks([
|
||||
['PositionComponent', 'RenderComponent'],
|
||||
['PositionComponent', 'VelocityComponent'],
|
||||
['PositionComponent', 'HealthComponent', 'WeaponComponent']
|
||||
]);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 位掩码调试工具
|
||||
|
||||
```typescript
|
||||
// 位掩码调试工具
|
||||
class MaskDebugger {
|
||||
private optimizer = BitMaskOptimizer.getInstance();
|
||||
|
||||
// 可视化位掩码
|
||||
visualizeMask(mask: bigint, maxBits: number = 16): string {
|
||||
const binary = mask.toString(2).padStart(maxBits, '0');
|
||||
const components = this.optimizer.maskToComponentNames(mask);
|
||||
|
||||
let visualization = `位掩码: ${mask} (二进制: ${binary})\n`;
|
||||
visualization += `组件: ${components.join(', ')}\n`;
|
||||
visualization += `可视化: `;
|
||||
|
||||
for (let i = maxBits - 1; i >= 0; i--) {
|
||||
const bit = (mask & (1n << BigInt(i))) !== 0n ? '1' : '0';
|
||||
visualization += bit;
|
||||
if (i % 4 === 0 && i > 0) visualization += ' ';
|
||||
}
|
||||
|
||||
return visualization;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 组件注册
|
||||
|
||||
```typescript
|
||||
// 在游戏初始化时注册所有组件类型
|
||||
function initializeComponentTypes() {
|
||||
const optimizer = BitMaskOptimizer.getInstance();
|
||||
|
||||
// 按使用频率注册(常用的组件分配较小的位位置)
|
||||
optimizer.registerComponentType('PositionComponent'); // 位置0
|
||||
optimizer.registerComponentType('VelocityComponent'); // 位置1
|
||||
optimizer.registerComponentType('HealthComponent'); // 位置2
|
||||
optimizer.registerComponentType('RenderComponent'); // 位置3
|
||||
// ... 其他组件
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 掩码缓存管理
|
||||
|
||||
```typescript
|
||||
// 定期清理掩码缓存以避免内存泄漏
|
||||
setInterval(() => {
|
||||
const optimizer = BitMaskOptimizer.getInstance();
|
||||
const stats = optimizer.getCacheStats();
|
||||
|
||||
// 如果缓存过大,清理一部分
|
||||
if (stats.size > 1000) {
|
||||
optimizer.clearCache();
|
||||
console.log('位掩码缓存已清理');
|
||||
}
|
||||
}, 60000); // 每分钟检查一次
|
||||
```
|
||||
|
||||
## 总结
|
||||
|
||||
位掩码是ECS框架中的核心优化技术,它提供了:
|
||||
|
||||
1. **极快的查询速度** - 位运算比遍历快数百倍
|
||||
2. **内存效率** - 用一个数字表示复杂的组件组合
|
||||
3. **批量操作优化** - 可以快速处理大量实体
|
||||
4. **灵活的查询构建** - 支持复杂的组件组合查询
|
||||
|
||||
通过理解和正确使用位掩码,可以显著提升游戏的性能表现。记住要在游戏初始化时注册组件类型,预计算常用掩码,并合理管理缓存。

# 组件设计最佳实践指南
|
||||
|
||||
组件是ECS架构的核心,设计良好的组件是构建高质量游戏的基础。本指南将教你如何设计出清晰、高效、可维护的组件。
|
||||
|
||||
## 组件设计原则
|
||||
|
||||
### 1. 数据为主,逻辑为辅
|
||||
|
||||
**核心理念:** 组件主要存储数据,复杂逻辑放在系统中处理。
|
||||
|
||||
```typescript
|
||||
// ✅ 好的设计:主要是数据
|
||||
class HealthComponent extends Component {
|
||||
public maxHealth: number;
|
||||
public currentHealth: number;
|
||||
public regenRate: number = 0;
|
||||
public lastDamageTime: number = 0;
|
||||
|
||||
constructor(maxHealth: number = 100) {
|
||||
super();
|
||||
this.maxHealth = maxHealth;
|
||||
this.currentHealth = maxHealth;
|
||||
}
|
||||
|
||||
// 简单的辅助方法是可以的
|
||||
isDead(): boolean {
|
||||
return this.currentHealth <= 0;
|
||||
}
|
||||
|
||||
getHealthPercentage(): number {
|
||||
return this.currentHealth / this.maxHealth;
|
||||
}
|
||||
}
|
||||
|
||||
// ❌ 不好的设计:包含太多逻辑
|
||||
class BadHealthComponent extends Component {
|
||||
public maxHealth: number;
|
||||
public currentHealth: number;
|
||||
|
||||
takeDamage(damage: number) {
|
||||
this.currentHealth -= damage;
|
||||
|
||||
// 这些逻辑应该在系统中处理
|
||||
if (this.currentHealth <= 0) {
|
||||
this.entity.destroy(); // 销毁逻辑
|
||||
this.playDeathSound(); // 音效逻辑
|
||||
this.createDeathEffect(); // 特效逻辑
|
||||
this.updatePlayerScore(100); // 分数逻辑
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 单一职责原则
|
||||
|
||||
每个组件只负责一个方面的数据。
|
||||
|
||||
```typescript
|
||||
// ✅ 好的设计:单一职责
|
||||
class PositionComponent extends Component {
|
||||
public x: number = 0;
|
||||
public y: number = 0;
|
||||
|
||||
constructor(x: number = 0, y: number = 0) {
|
||||
super();
|
||||
this.x = x;
|
||||
this.y = y;
|
||||
}
|
||||
}
|
||||
|
||||
class VelocityComponent extends Component {
|
||||
public x: number = 0;
|
||||
public y: number = 0;
|
||||
public maxSpeed: number = 100;
|
||||
|
||||
constructor(x: number = 0, y: number = 0) {
|
||||
super();
|
||||
this.x = x;
|
||||
this.y = y;
|
||||
}
|
||||
}
|
||||
|
||||
class RotationComponent extends Component {
|
||||
public angle: number = 0;
|
||||
public angularVelocity: number = 0;
|
||||
|
||||
constructor(angle: number = 0) {
|
||||
super();
|
||||
this.angle = angle;
|
||||
}
|
||||
}
|
||||
|
||||
// ❌ 不好的设计:职责混乱
|
||||
class TransformComponent extends Component {
|
||||
public x: number = 0;
|
||||
public y: number = 0;
|
||||
public velocityX: number = 0;
|
||||
public velocityY: number = 0;
|
||||
public angle: number = 0;
|
||||
public scale: number = 1;
|
||||
public health: number = 100; // 和变换无关
|
||||
public ammo: number = 30; // 和变换无关
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 组合优于继承
|
||||
|
||||
使用多个小组件组合,而不是大而全的组件继承。
|
||||
|
||||
```typescript
|
||||
// ✅ 好的设计:组合方式
|
||||
class Player {
|
||||
constructor(scene: Scene) {
|
||||
const player = scene.createEntity("Player");
|
||||
|
||||
// 通过组合不同组件实现功能
|
||||
player.addComponent(new PositionComponent(100, 100));
|
||||
player.addComponent(new VelocityComponent());
|
||||
player.addComponent(new HealthComponent(100));
|
||||
player.addComponent(new PlayerInputComponent());
|
||||
player.addComponent(new WeaponComponent());
|
||||
player.addComponent(new InventoryComponent());
|
||||
|
||||
return player;
|
||||
}
|
||||
}
|
||||
|
||||
// 创建不同类型的实体很容易
|
||||
class Enemy {
|
||||
constructor(scene: Scene) {
|
||||
const enemy = scene.createEntity("Enemy");
|
||||
|
||||
// 复用相同的组件,但组合不同
|
||||
enemy.addComponent(new PositionComponent(200, 200));
|
||||
enemy.addComponent(new VelocityComponent());
|
||||
enemy.addComponent(new HealthComponent(50));
|
||||
enemy.addComponent(new AIComponent()); // 不同:AI而不是玩家输入
|
||||
enemy.addComponent(new WeaponComponent()); // 相同:都有武器
|
||||
// 没有库存组件
|
||||
|
||||
return enemy;
|
||||
}
|
||||
}
|
||||
|
||||
// ❌ 不好的设计:继承方式
|
||||
class GameObject {
|
||||
public x: number;
|
||||
public y: number;
|
||||
public health: number;
|
||||
// ... 很多属性
|
||||
}
|
||||
|
||||
class PlayerGameObject extends GameObject {
|
||||
public input: InputData;
|
||||
public inventory: Item[];
|
||||
// 强制继承了不需要的属性
|
||||
}
|
||||
|
||||
class EnemyGameObject extends GameObject {
|
||||
public ai: AIData;
|
||||
// 继承了不需要的库存等属性
|
||||
}
|
||||
```
|
||||
|
||||
## 常见组件类型和设计
|
||||
|
||||
### 1. 数据组件(Data Components)
|
||||
|
||||
纯数据存储,没有或很少有方法。
|
||||
|
||||
```typescript
|
||||
// 位置信息
|
||||
class PositionComponent extends Component {
|
||||
public x: number;
|
||||
public y: number;
|
||||
|
||||
constructor(x: number = 0, y: number = 0) {
|
||||
super();
|
||||
this.x = x;
|
||||
this.y = y;
|
||||
}
|
||||
|
||||
// 简单的辅助方法
|
||||
distanceTo(other: PositionComponent): number {
|
||||
const dx = this.x - other.x;
|
||||
const dy = this.y - other.y;
|
||||
return Math.sqrt(dx * dx + dy * dy);
|
||||
}
|
||||
|
||||
set(x: number, y: number) {
|
||||
this.x = x;
|
||||
this.y = y;
|
||||
}
|
||||
}
|
||||
|
||||
// 统计信息
|
||||
class StatsComponent extends Component {
|
||||
public strength: number = 10;
|
||||
public agility: number = 10;
|
||||
public intelligence: number = 10;
|
||||
public vitality: number = 10;
|
||||
|
||||
// 计算派生属性
|
||||
getMaxHealth(): number {
|
||||
return this.vitality * 10;
|
||||
}
|
||||
|
||||
getDamage(): number {
|
||||
return this.strength * 2;
|
||||
}
|
||||
|
||||
getMoveSpeed(): number {
|
||||
return this.agility * 5;
|
||||
}
|
||||
}
|
||||
|
||||
// 渲染信息
|
||||
class SpriteComponent extends Component {
|
||||
public textureName: string;
|
||||
public width: number;
|
||||
public height: number;
|
||||
public tint: number = 0xFFFFFF;
|
||||
public alpha: number = 1.0;
|
||||
public visible: boolean = true;
|
||||
|
||||
constructor(textureName: string, width: number = 0, height: number = 0) {
|
||||
super();
|
||||
this.textureName = textureName;
|
||||
this.width = width;
|
||||
this.height = height;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 标记组件(Tag Components)
|
||||
|
||||
用于标识实体状态或类型的空组件。
|
||||
|
||||
```typescript
|
||||
// 标记组件通常不包含数据
|
||||
class PlayerComponent extends Component {
|
||||
// 空组件,仅用于标记这是玩家实体
|
||||
}
|
||||
|
||||
class EnemyComponent extends Component {
|
||||
// 空组件,仅用于标记这是敌人实体
|
||||
}
|
||||
|
||||
class DeadComponent extends Component {
|
||||
// 标记实体已死亡
|
||||
public deathTime: number;
|
||||
|
||||
constructor() {
|
||||
super();
|
||||
this.deathTime = Time.totalTime;
|
||||
}
|
||||
}
|
||||
|
||||
class InvincibleComponent extends Component {
|
||||
// 标记实体无敌状态
|
||||
public duration: number;
|
||||
|
||||
constructor(duration: number = 2.0) {
|
||||
super();
|
||||
this.duration = duration;
|
||||
}
|
||||
}
|
||||
|
||||
// 使用标记组件进行查询
|
||||
class GameSystem {
|
||||
updatePlayers() {
|
||||
// 只处理玩家实体
|
||||
const players = this.scene.findEntitiesWithComponent(PlayerComponent);
|
||||
// ...
|
||||
}
|
||||
|
||||
updateEnemies() {
|
||||
// 只处理敌人实体
|
||||
const enemies = this.scene.findEntitiesWithComponent(EnemyComponent);
|
||||
// ...
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 行为组件(Behavior Components)
|
||||
|
||||
包含简单行为逻辑的组件。
|
||||
|
||||
```typescript
|
||||
class WeaponComponent extends Component {
|
||||
public damage: number;
|
||||
public fireRate: number;
|
||||
public ammo: number;
|
||||
public maxAmmo: number;
|
||||
public lastFireTime: number = 0;
|
||||
|
||||
constructor(damage: number = 10, fireRate: number = 0.5) {
|
||||
super();
|
||||
this.damage = damage;
|
||||
this.fireRate = fireRate;
|
||||
this.maxAmmo = 30;
|
||||
this.ammo = this.maxAmmo;
|
||||
}
|
||||
|
||||
canFire(): boolean {
|
||||
return this.ammo > 0 &&
|
||||
Time.totalTime - this.lastFireTime >= this.fireRate;
|
||||
}
|
||||
|
||||
fire(): boolean {
|
||||
if (this.canFire()) {
|
||||
this.ammo--;
|
||||
this.lastFireTime = Time.totalTime;
|
||||
return true;
|
||||
}
|
||||
return false;
|
||||
}
|
||||
|
||||
reload() {
|
||||
this.ammo = this.maxAmmo;
|
||||
}
|
||||
|
||||
getAmmoPercentage(): number {
|
||||
return this.ammo / this.maxAmmo;
|
||||
}
|
||||
}
|
||||
|
||||
class InventoryComponent extends Component {
|
||||
private items: Map<string, number> = new Map();
|
||||
public maxCapacity: number = 20;
|
||||
|
||||
addItem(itemType: string, quantity: number = 1): boolean {
|
||||
if (this.getTotalItems() + quantity > this.maxCapacity) {
|
||||
return false;
|
||||
}
|
||||
|
||||
const current = this.items.get(itemType) || 0;
|
||||
this.items.set(itemType, current + quantity);
|
||||
return true;
|
||||
}
|
||||
|
||||
removeItem(itemType: string, quantity: number = 1): boolean {
|
||||
const current = this.items.get(itemType) || 0;
|
||||
if (current < quantity) {
|
||||
return false;
|
||||
}
|
||||
|
||||
const newAmount = current - quantity;
|
||||
if (newAmount === 0) {
|
||||
this.items.delete(itemType);
|
||||
} else {
|
||||
this.items.set(itemType, newAmount);
|
||||
}
|
||||
return true;
|
||||
}
|
||||
|
||||
hasItem(itemType: string, quantity: number = 1): boolean {
|
||||
const current = this.items.get(itemType) || 0;
|
||||
return current >= quantity;
|
||||
}
|
||||
|
||||
getTotalItems(): number {
|
||||
let total = 0;
|
||||
this.items.forEach(quantity => total += quantity);
|
||||
return total;
|
||||
}
|
||||
|
||||
getItems(): Map<string, number> {
|
||||
return new Map(this.items); // 返回副本
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 组件通信和依赖
|
||||
|
||||
### 1. 组件间通信
|
||||
|
||||
组件间不应直接通信,通过系统或事件系统进行通信。
|
||||
|
||||
```typescript
|
||||
// ✅ 好的设计:通过事件通信
|
||||
class HealthComponent extends Component {
|
||||
public currentHealth: number;
|
||||
public maxHealth: number;
|
||||
|
||||
takeDamage(damage: number) {
|
||||
this.currentHealth -= damage;
|
||||
|
||||
// 发送事件,让其他系统响应
|
||||
// 注意:需要在实际使用中获取EntityManager实例
|
||||
// 示例:entityManager.eventBus.emit('health:damaged', {...});
|
||||
|
||||
if (this.currentHealth <= 0) {
|
||||
// 示例:entityManager.eventBus.emit('health:died', {...});
|
||||
console.log('实体死亡');
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// 其他组件响应事件
|
||||
class AnimationComponent extends Component {
|
||||
onAddedToEntity() {
|
||||
super.onAddedToEntity();
|
||||
|
||||
// 监听受伤事件(需要在实际使用中获取EntityManager实例)
|
||||
// 示例:entityManager.eventBus.on('health:damaged', this.onDamaged, { context: this });
|
||||
}
|
||||
|
||||
onRemovedFromEntity() {
|
||||
// 事件监听会在组件移除时自动清理
|
||||
// 如需手动清理,保存listenerId并调用eventBus.off()
|
||||
super.onRemovedFromEntity();
|
||||
}
|
||||
|
||||
private onDamaged(data: any) {
|
||||
if (data.entity === this.entity) {
|
||||
this.playHurtAnimation();
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// ❌ 不好的设计:直接依赖其他组件
|
||||
class BadHealthComponent extends Component {
|
||||
takeDamage(damage: number) {
|
||||
this.currentHealth -= damage;
|
||||
|
||||
// 直接操作其他组件
|
||||
const animation = this.entity.getComponent(AnimationComponent);
|
||||
if (animation) {
|
||||
animation.playHurtAnimation(); // 紧耦合
|
||||
}
|
||||
|
||||
const sound = this.entity.getComponent(SoundComponent);
|
||||
if (sound) {
|
||||
sound.playHurtSound(); // 紧耦合
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 可选依赖
|
||||
|
||||
有时组件需要其他组件配合工作,但应该优雅处理缺失的情况。
|
||||
|
||||
```typescript
|
||||
class MovementComponent extends Component {
|
||||
public speed: number = 100;
|
||||
|
||||
update() {
|
||||
// 可选依赖:输入组件
|
||||
const input = this.entity.getComponent(InputComponent);
|
||||
const velocity = this.entity.getComponent(VelocityComponent);
|
||||
|
||||
if (input && velocity) {
|
||||
// 根据输入设置速度
|
||||
velocity.x = input.horizontal * this.speed;
|
||||
velocity.y = input.vertical * this.speed;
|
||||
}
|
||||
|
||||
// 可选依赖:AI组件
|
||||
const ai = this.entity.getComponent(AIComponent);
|
||||
if (ai && velocity && !input) {
|
||||
// AI控制移动(如果没有输入)
|
||||
velocity.x = ai.moveDirection.x * this.speed;
|
||||
velocity.y = ai.moveDirection.y * this.speed;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 组件性能优化
|
||||
|
||||
### 1. 对象池优化
|
||||
|
||||
对于频繁创建/销毁的组件,使用对象池。
|
||||
|
||||
```typescript
|
||||
class PooledBulletComponent extends Component {
|
||||
public damage: number = 10;
|
||||
public speed: number = 200;
|
||||
public direction: { x: number; y: number } = { x: 0, y: 0 };
|
||||
public lifetime: number = 5.0;
|
||||
private currentLifetime: number = 0;
|
||||
|
||||
// 重置组件状态,用于对象池
|
||||
reset() {
|
||||
this.damage = 10;
|
||||
this.speed = 200;
|
||||
this.direction.set(0, 0);
|
||||
this.lifetime = 5.0;
|
||||
this.currentLifetime = 0;
|
||||
}
|
||||
|
||||
// 配置子弹
|
||||
configure(damage: number, speed: number, direction: { x: number; y: number }) {
|
||||
this.damage = damage;
|
||||
this.speed = speed;
|
||||
this.direction = direction.copy();
|
||||
}
|
||||
|
||||
update() {
|
||||
this.currentLifetime += Time.deltaTime;
|
||||
|
||||
if (this.currentLifetime >= this.lifetime) {
|
||||
// 生命周期结束,回收到对象池
|
||||
BulletPool.release(this.entity);
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// 对象池管理
|
||||
class BulletPool {
|
||||
private static pool: Entity[] = [];
|
||||
|
||||
static get(): Entity {
|
||||
if (this.pool.length > 0) {
|
||||
const bullet = this.pool.pop()!;
|
||||
bullet.enabled = true;
|
||||
return bullet;
|
||||
} else {
|
||||
return this.createBullet();
|
||||
}
|
||||
}
|
||||
|
||||
static release(bullet: Entity) {
|
||||
bullet.enabled = false;
|
||||
bullet.getComponent(PooledBulletComponent)?.reset();
|
||||
this.pool.push(bullet);
|
||||
}
|
||||
|
||||
private static createBullet(): Entity {
|
||||
const bullet = Core.scene.createEntity("Bullet");
|
||||
bullet.addComponent(new PooledBulletComponent());
|
||||
bullet.addComponent(new PositionComponent());
|
||||
bullet.addComponent(new VelocityComponent());
|
||||
return bullet;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 数据紧凑性
|
||||
|
||||
保持组件数据紧凑,避免不必要的对象分配。
|
||||
|
||||
```typescript
|
||||
// ✅ 好的设计:紧凑的数据结构
|
||||
class ParticleComponent extends Component {
|
||||
// 使用基本类型,避免对象分配
|
||||
public x: number = 0;
|
||||
public y: number = 0;
|
||||
public velocityX: number = 0;
|
||||
public velocityY: number = 0;
|
||||
public life: number = 1.0;
|
||||
public maxLife: number = 1.0;
|
||||
public size: number = 1.0;
|
||||
public color: number = 0xFFFFFF;
|
||||
|
||||
// 计算属性,避免存储冗余数据
|
||||
get alpha(): number {
|
||||
return this.life / this.maxLife;
|
||||
}
|
||||
}
|
||||
|
||||
// ❌ 不好的设计:过多对象分配
|
||||
class BadParticleComponent extends Component {
|
||||
public position: { x: number; y: number } = { x: 0, y: 0 }; // 对象分配
|
||||
public velocity: { x: number; y: number } = { x: 0, y: 0 }; // 对象分配
|
||||
public color: Color = new Color(); // 对象分配
|
||||
public transform: Transform = new Transform(); // 对象分配
|
||||
|
||||
// 冗余数据
|
||||
public alpha: number = 1.0;
|
||||
public life: number = 1.0;
|
||||
public maxLife: number = 1.0;
|
||||
}
|
||||
```
|
||||
|
||||
## 组件调试和测试
|
||||
|
||||
### 1. 调试友好的组件
|
||||
|
||||
```typescript
|
||||
class DebugFriendlyComponent extends Component {
|
||||
public someValue: number = 0;
|
||||
private debugName: string;
|
||||
|
||||
constructor(debugName: string = "Unknown") {
|
||||
super();
|
||||
this.debugName = debugName;
|
||||
}
|
||||
|
||||
// 提供有用的调试信息
|
||||
toString(): string {
|
||||
return `${this.constructor.name}(${this.debugName}): value=${this.someValue}`;
|
||||
}
|
||||
|
||||
// 验证组件状态
|
||||
validate(): boolean {
|
||||
if (this.someValue < 0) {
|
||||
console.warn(`${this} has invalid value: ${this.someValue}`);
|
||||
return false;
|
||||
}
|
||||
return true;
|
||||
}
|
||||
|
||||
// 获取调试信息
|
||||
getDebugInfo(): any {
|
||||
return {
|
||||
name: this.debugName,
|
||||
value: this.someValue,
|
||||
entityId: this.entity?.id,
|
||||
isValid: this.validate()
|
||||
};
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 单元测试
|
||||
|
||||
```typescript
|
||||
// 组件测试示例
|
||||
describe('HealthComponent', () => {
|
||||
let healthComponent: HealthComponent;
|
||||
|
||||
beforeEach(() => {
|
||||
healthComponent = new HealthComponent(100);
|
||||
});
|
||||
|
||||
test('初始状态正确', () => {
|
||||
expect(healthComponent.currentHealth).toBe(100);
|
||||
expect(healthComponent.maxHealth).toBe(100);
|
||||
expect(healthComponent.isDead()).toBe(false);
|
||||
});
|
||||
|
||||
test('受伤功能正确', () => {
|
||||
healthComponent.takeDamage(30);
|
||||
expect(healthComponent.currentHealth).toBe(70);
|
||||
expect(healthComponent.getHealthPercentage()).toBe(0.7);
|
||||
});
|
||||
|
||||
test('死亡检测正确', () => {
|
||||
healthComponent.takeDamage(100);
|
||||
expect(healthComponent.isDead()).toBe(true);
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
## 常见问题和最佳实践
|
||||
|
||||
### Q: 组件应该有多大?
|
||||
|
||||
A: 组件应该尽可能小和专注。如果一个组件有超过10个字段,考虑拆分。
|
||||
|
||||
### Q: 组件可以包含方法吗?
|
||||
|
||||
A: 可以,但应该是简单的辅助方法。复杂逻辑应该在系统中处理。
|
||||
|
||||
### Q: 如何处理组件之间的依赖?
|
||||
|
||||
A:
|
||||
1. 优先使用组合而不是依赖
|
||||
2. 通过事件系统通信
|
||||
3. 在系统中处理组件间的协调
|
||||
|
||||
### Q: 什么时候使用继承?
|
||||
|
||||
A: 很少使用。只在有明确的"是一个"关系时使用,如:
|
||||
|
||||
```typescript
|
||||
abstract class ColliderComponent extends Component {
|
||||
abstract checkCollision(other: ColliderComponent): boolean;
|
||||
}
|
||||
|
||||
class CircleColliderComponent extends ColliderComponent {
|
||||
public radius: number;
|
||||
|
||||
checkCollision(other: ColliderComponent): boolean {
|
||||
// 圆形碰撞检测
|
||||
}
|
||||
}
|
||||
|
||||
class BoxColliderComponent extends ColliderComponent {
|
||||
public width: number;
|
||||
public height: number;
|
||||
|
||||
checkCollision(other: ColliderComponent): boolean {
|
||||
// 方形碰撞检测
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
遵循这些原则,你就能设计出高质量、易维护的组件系统!

## ECS 架构基础
|
||||
|
||||
### 什么是 ECS?
|
||||
|
||||
ECS (Entity-Component-System) 是一种编程架构模式,将游戏对象分解为三个独立的部分:
|
||||
|
||||
**传统面向对象方式:**
|
||||
```typescript
|
||||
// 传统继承方式 - 问题很多
|
||||
class GameObject {
|
||||
x: number; y: number;
|
||||
render() { ... }
|
||||
update() { ... }
|
||||
}
|
||||
|
||||
class Player extends GameObject {
|
||||
health: number;
|
||||
shoot() { ... }
|
||||
}
|
||||
|
||||
class Enemy extends Player { // 敌人需要射击但不需要玩家控制?
|
||||
ai() { ... }
|
||||
}
|
||||
```
|
||||
|
||||
**ECS 方式:**
|
||||
```typescript
|
||||
// 数据和逻辑分离,灵活组合
|
||||
const player = createEntity()
|
||||
.add(PositionComponent) // 位置数据
|
||||
.add(HealthComponent) // 生命值数据
|
||||
.add(PlayerInputComponent) // 玩家输入标记
|
||||
|
||||
const enemy = createEntity()
|
||||
.add(PositionComponent) // 复用位置数据
|
||||
.add(HealthComponent) // 复用生命值数据
|
||||
.add(AIComponent) // AI标记
|
||||
|
||||
// 系统处理具有特定组件的实体
|
||||
MovementSystem.process([PositionComponent, VelocityComponent]);
|
||||
```
|
||||
|
||||
### ECS 的优势
|
||||
|
||||
1. **灵活组合** - 像搭积木一样组装功能
|
||||
2. **代码复用** - 组件可以在不同实体间复用
|
||||
3. **性能优化** - 数据连续存储,缓存友好
|
||||
4. **并行处理** - 系统间相互独立,可以并行执行
|
||||
5. **易于测试** - 组件和系统可以独立测试
|
||||
|
||||
### 实际应用场景
|
||||
|
||||
**游戏开发中的例子:**
|
||||
- **RPG游戏**:玩家、NPC、怪物都有位置和生命值,但只有玩家有输入组件
|
||||
- **射击游戏**:子弹、玩家、敌人都有位置和碰撞体,但行为完全不同
|
||||
- **策略游戏**:建筑、单位、资源都是实体,通过不同组件组合实现功能
|
||||
|
||||
## 性能优化技术
|
||||
|
||||
### 组件索引系统
|
||||
|
||||
**问题:** 没有索引时,查找组件需要遍历所有实体
|
||||
```typescript
|
||||
// 慢的方式:线性搜索 O(n)
|
||||
function findEntitiesWithHealth() {
|
||||
const result = [];
|
||||
for (const entity of allEntities) { // 遍历10万个实体
|
||||
if (entity.hasComponent(HealthComponent)) {
|
||||
result.push(entity);
|
||||
}
|
||||
}
|
||||
return result;
|
||||
}
|
||||
```
|
||||
|
||||
**解决方案:** 建立索引,直接访问
|
||||
```typescript
|
||||
// 快的方式:索引查找 O(1)
|
||||
const healthIndex = componentIndex.get(HealthComponent);
|
||||
const entitiesWithHealth = healthIndex.getEntities(); // 直接获取
|
||||
```
|
||||
|
||||
**应用场景:**
|
||||
- 频繁查询特定组件的实体
|
||||
- 大规模实体场景(数千到数万个实体)
|
||||
- 实时游戏中的系统更新
|
||||
|
||||
### 索引类型选择指南
|
||||
|
||||
框架提供两种索引类型,选择合适的类型对性能至关重要:
|
||||
|
||||
#### 🔸 哈希索引 (Hash Index)
|
||||
|
||||
**适用场景:**
|
||||
- 实体数量较多(> 1000个)
|
||||
- 组件数据变化不频繁
|
||||
- 需要快速查找特定实体
|
||||
|
||||
**优势:**
|
||||
- 查询速度极快 O(1)
|
||||
- 内存使用相对较少
|
||||
- 适合大量实体
|
||||
|
||||
**缺点:**
|
||||
- 添加/删除组件时有额外开销
|
||||
- 不适合频繁变化的组件
|
||||
|
||||
```typescript
|
||||
// 适合哈希索引的组件
|
||||
componentIndex.setIndexType(PositionComponent, 'hash'); // 位置变化不频繁
|
||||
componentIndex.setIndexType(HealthComponent, 'hash'); // 生命值组件稳定
|
||||
componentIndex.setIndexType(PlayerComponent, 'hash'); // 玩家标记组件
|
||||
```
|
||||
|
||||
#### 🔹 位图索引 (Bitmap Index)
|
||||
|
||||
**适用场景:**
|
||||
- 组件频繁添加/删除
|
||||
- 实体数量适中(< 10000个)
|
||||
- 需要批量操作
|
||||
|
||||
**优势:**
|
||||
- 添加/删除组件极快
|
||||
- 批量查询效率高
|
||||
- 内存访问模式好
|
||||
|
||||
**缺点:**
|
||||
- 随实体数量增长,内存占用增加
|
||||
- 稀疏数据时效率降低
|
||||
|
||||
```typescript
|
||||
// 适合位图索引的组件
|
||||
componentIndex.setIndexType(BuffComponent, 'bitmap'); // Buff经常添加删除
|
||||
componentIndex.setIndexType(TemporaryComponent, 'bitmap'); // 临时组件
|
||||
componentIndex.setIndexType(StateComponent, 'bitmap'); // 状态组件变化频繁
|
||||
```
|
||||
|
||||
#### 📊 选择决策表
|
||||
|
||||
| 考虑因素 | 哈希索引 (Hash) | 位图索引 (Bitmap) |
|
||||
|---------|----------------|-------------------|
|
||||
| **实体数量** | > 1,000 | < 10,000 |
|
||||
| **组件变化频率** | 低频变化 | 高频变化 |
|
||||
| **查询频率** | 高频查询 | 中等查询 |
|
||||
| **内存使用** | 较少 | 随实体数增加 |
|
||||
| **批量操作** | 一般 | 优秀 |
|
||||
|
||||
#### 🤔 快速决策流程
|
||||
|
||||
**第一步:判断组件变化频率**
|
||||
- 组件经常添加/删除? → 选择 **位图索引**
|
||||
- 组件相对稳定? → 继续第二步
|
||||
|
||||
**第二步:判断实体数量**
|
||||
- 实体数量 > 1000? → 选择 **哈希索引**
|
||||
- 实体数量 < 1000? → 选择 **位图索引**
|
||||
|
||||
**第三步:特殊情况**
|
||||
- 需要频繁批量操作? → 选择 **位图索引**
|
||||
- 内存使用很重要? → 选择 **哈希索引**
|
||||
|
||||
#### 🎮 实际游戏中的选择示例
|
||||
|
||||
**射击游戏:**
|
||||
```typescript
|
||||
// 稳定组件用哈希索引
|
||||
componentIndex.setIndexType(PositionComponent, 'hash'); // 实体位置稳定存在
|
||||
componentIndex.setIndexType(HealthComponent, 'hash'); // 生命值组件持续存在
|
||||
componentIndex.setIndexType(WeaponComponent, 'hash'); // 武器组件不常变化
|
||||
|
||||
// 变化组件用位图索引
|
||||
componentIndex.setIndexType(BuffComponent, 'bitmap'); // Buff频繁添加删除
|
||||
componentIndex.setIndexType(ReloadingComponent, 'bitmap'); // 装弹状态临时组件
|
||||
```
|
||||
|
||||
**策略游戏:**
|
||||
```typescript
|
||||
// 大量单位,核心组件用哈希
|
||||
componentIndex.setIndexType(UnitComponent, 'hash'); // 单位类型稳定
|
||||
componentIndex.setIndexType(OwnerComponent, 'hash'); // 所属玩家稳定
|
||||
|
||||
// 状态组件用位图
|
||||
componentIndex.setIndexType(SelectedComponent, 'bitmap'); // 选中状态常变化
|
||||
componentIndex.setIndexType(MovingComponent, 'bitmap'); // 移动状态变化
|
||||
componentIndex.setIndexType(AttackingComponent, 'bitmap'); // 攻击状态临时
|
||||
```
|
||||
|
||||
**RPG游戏:**
|
||||
```typescript
|
||||
// 角色核心属性用哈希
|
||||
componentIndex.setIndexType(StatsComponent, 'hash'); // 属性组件稳定
|
||||
componentIndex.setIndexType(InventoryComponent, 'hash'); // 背包组件稳定
|
||||
componentIndex.setIndexType(LevelComponent, 'hash'); // 等级组件稳定
|
||||
|
||||
// 临时状态用位图
|
||||
componentIndex.setIndexType(StatusEffectComponent, 'bitmap'); // 状态效果变化
|
||||
componentIndex.setIndexType(QuestComponent, 'bitmap'); // 任务状态变化
|
||||
componentIndex.setIndexType(CombatComponent, 'bitmap'); // 战斗状态临时
|
||||
```
|
||||
|
||||
#### ❌ 常见选择错误
|
||||
|
||||
**错误示例1:大量实体使用位图索引**
|
||||
```typescript
|
||||
// ❌ 错误:10万个单位用位图索引,内存爆炸
|
||||
const entityCount = 100000;
|
||||
componentIndex.setIndexType(UnitComponent, 'bitmap'); // 内存占用过大!
|
||||
|
||||
// ✅ 正确:大量实体用哈希索引
|
||||
componentIndex.setIndexType(UnitComponent, 'hash');
|
||||
```
|
||||
|
||||
**错误示例2:频繁变化组件用哈希索引**
|
||||
```typescript
|
||||
// ❌ 错误:Buff频繁添加删除,哈希索引效率低
|
||||
componentIndex.setIndexType(BuffComponent, 'hash'); // 添加删除慢!
|
||||
|
||||
// ✅ 正确:变化频繁的组件用位图索引
|
||||
componentIndex.setIndexType(BuffComponent, 'bitmap');
|
||||
```
|
||||
|
||||
**错误示例3:不考虑实际使用场景**
|
||||
```typescript
|
||||
// ❌ 错误:所有组件都用同一种索引
|
||||
componentIndex.setIndexType(PositionComponent, 'hash');
|
||||
componentIndex.setIndexType(BuffComponent, 'hash'); // 应该用bitmap
|
||||
componentIndex.setIndexType(TemporaryComponent, 'hash'); // 应该用bitmap
|
||||
|
||||
// ✅ 正确:根据组件特性选择
|
||||
componentIndex.setIndexType(PositionComponent, 'hash'); // 稳定组件
|
||||
componentIndex.setIndexType(BuffComponent, 'bitmap'); // 变化组件
|
||||
componentIndex.setIndexType(TemporaryComponent, 'bitmap'); // 临时组件
|
||||
```
|
||||
|
||||
### Archetype 系统
|
||||
|
||||
**什么是 Archetype?**
|
||||
Archetype(原型)是具有相同组件组合的实体分组。
|
||||
|
||||
**没有 Archetype 的问题:**
|
||||
```typescript
|
||||
// 每次都要检查每个实体的组件组合
|
||||
for (const entity of allEntities) {
|
||||
if (entity.has(Position) && entity.has(Velocity) && !entity.has(Frozen)) {
|
||||
// 处理移动
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Archetype 的解决方案:**
|
||||
```typescript
|
||||
// 实体按组件组合自动分组
|
||||
const movableArchetype = [Position, Velocity, !Frozen];
|
||||
const movableEntities = archetypeSystem.getEntities(movableArchetype);
|
||||
// 直接处理,无需逐个检查
|
||||
```
|
||||
|
||||
**应用场景:**
|
||||
- 大量实体的游戏(RTS、MMO)
|
||||
- 频繁的实体查询操作
|
||||
- 批量处理相同类型的实体
|
||||
|
||||
### 脏标记系统
|
||||
|
||||
**什么是脏标记?**
|
||||
脏标记(Dirty Tracking)追踪哪些数据发生了变化,避免处理未变化的数据。
|
||||
|
||||
**没有脏标记的问题:**
|
||||
```typescript
|
||||
// 每帧都重新计算所有实体,即使它们没有移动
|
||||
function renderSystem() {
|
||||
for (const entity of entities) {
|
||||
updateRenderPosition(entity); // 浪费计算
|
||||
updateRenderRotation(entity); // 浪费计算
|
||||
updateRenderScale(entity); // 浪费计算
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**脏标记的解决方案:**
|
||||
```typescript
|
||||
// 只处理发生变化的实体
|
||||
function renderSystem() {
|
||||
const dirtyEntities = dirtyTracking.getDirtyEntities();
|
||||
for (const entity of dirtyEntities) {
|
||||
if (dirtyTracking.isDirty(entity, PositionComponent)) {
|
||||
updateRenderPosition(entity); // 只在需要时计算
|
||||
}
|
||||
if (dirtyTracking.isDirty(entity, RotationComponent)) {
|
||||
updateRenderRotation(entity);
|
||||
}
|
||||
}
|
||||
dirtyTracking.clearDirtyFlags();
|
||||
}
|
||||
```
|
||||
|
||||
**应用场景:**
|
||||
- 渲染系统优化(只更新变化的物体)
|
||||
- 物理系统优化(只计算移动的物体)
|
||||
- UI更新优化(只刷新变化的界面元素)
|
||||
- 网络同步优化(只发送变化的数据)
|
||||
|
||||
**实际例子:**
|
||||
```typescript
|
||||
// 游戏中的应用
|
||||
class MovementSystem {
|
||||
process() {
|
||||
// 玩家移动时标记为脏
|
||||
if (playerInput.moved) {
|
||||
dirtyTracking.markDirty(player, PositionComponent);
|
||||
}
|
||||
|
||||
// 静止的敌人不会被标记为脏,渲染系统会跳过它们
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 事件系统
|
||||
|
||||
### 类型安全事件
|
||||
|
||||
**传统事件的问题:**
|
||||
```typescript
|
||||
// 类型不安全,容易出错
|
||||
eventEmitter.emit('player_died', playerData);
|
||||
eventEmitter.on('player_dead', handler); // 事件名拼写错误!
|
||||
```
|
||||
|
||||
**类型安全事件的解决方案:**
|
||||
```typescript
|
||||
// 编译时检查,避免错误
|
||||
enum GameEvents {
|
||||
PLAYER_DIED = 'player:died',
|
||||
LEVEL_COMPLETED = 'level:completed'
|
||||
}
|
||||
|
||||
eventBus.emit(GameEvents.PLAYER_DIED, { playerId: 123 });
|
||||
eventBus.on(GameEvents.PLAYER_DIED, (data) => {
|
||||
// data 类型自动推断
|
||||
});
|
||||
```
|
||||
|
||||
### 事件装饰器
|
||||
|
||||
**什么是装饰器?**
|
||||
装饰器让你用简单的语法自动注册事件监听器。
|
||||
|
||||
**传统方式:**
|
||||
```typescript
|
||||
class GameManager {
|
||||
constructor() {
|
||||
// 手动注册事件
|
||||
eventBus.on('entity:created', this.onEntityCreated.bind(this));
|
||||
eventBus.on('entity:destroyed', this.onEntityDestroyed.bind(this));
|
||||
eventBus.on('component:added', this.onComponentAdded.bind(this));
|
||||
}
|
||||
|
||||
onEntityCreated(data) { ... }
|
||||
onEntityDestroyed(data) { ... }
|
||||
onComponentAdded(data) { ... }
|
||||
}
|
||||
```
|
||||
|
||||
**装饰器方式:**
|
||||
```typescript
|
||||
class GameManager {
|
||||
@EventHandler('entity:created')
|
||||
onEntityCreated(data) { ... } // 自动注册
|
||||
|
||||
@EventHandler('entity:destroyed')
|
||||
onEntityDestroyed(data) { ... } // 自动注册
|
||||
|
||||
@EventHandler('component:added')
|
||||
onComponentAdded(data) { ... } // 自动注册
|
||||
}
|
||||
```
|
||||
|
||||
**应用场景:**
|
||||
- 游戏状态管理
|
||||
- UI更新响应
|
||||
- 音效播放触发
|
||||
- 成就系统检查
|
||||
|
||||
## 实体管理
|
||||
|
||||
### 实体生命周期
|
||||
|
||||
**创建实体的不同方式:**
|
||||
```typescript
|
||||
// 单个创建 - 适用于重要实体
|
||||
const player = scene.createEntity("Player");
|
||||
|
||||
// 批量创建 - 适用于大量相似实体
|
||||
const bullets = scene.createEntities(100, "Bullet");
|
||||
|
||||
// 延迟创建 - 避免性能峰值
|
||||
// 分批创建大量实体以避免单帧卡顿
|
||||
for (let i = 0; i < 100; i++) {
|
||||
setTimeout(() => {
|
||||
const batch = scene.createEntities(10, "Enemy");
|
||||
// 配置批次实体...
|
||||
}, i * 16); // 每16ms创建一批
|
||||
}
|
||||
```
|
||||
|
||||
### 查询系统
|
||||
|
||||
**流式API的优势:**
|
||||
```typescript
|
||||
// 传统方式:复杂的条件判断
|
||||
const result = [];
|
||||
for (const entity of entities) {
|
||||
if (entity.has(Position) &&
|
||||
entity.has(Velocity) &&
|
||||
!entity.has(Frozen) &&
|
||||
entity.tag === EntityTag.ENEMY) {
|
||||
result.push(entity);
|
||||
}
|
||||
}
|
||||
|
||||
// 流式API:清晰表达意图
|
||||
const result = entityManager
|
||||
.query()
|
||||
.withAll(Position, Velocity)
|
||||
.withNone(Frozen)
|
||||
.withTag(EntityTag.ENEMY)
|
||||
.execute();
|
||||
```
|
||||
|
||||
### 批量操作
|
||||
|
||||
**为什么需要批量操作?**
|
||||
```typescript
|
||||
// 慢的方式:逐个处理
|
||||
for (let i = 0; i < 1000; i++) {
|
||||
const bullet = createEntity();
|
||||
bullet.addComponent(new PositionComponent());
|
||||
bullet.addComponent(new VelocityComponent());
|
||||
}
|
||||
|
||||
// 快的方式:批量处理
|
||||
const bullets = scene.createEntities(1000, "Bullet");
|
||||
bullets.forEach(bullet => {
|
||||
bullet.addComponent(new PositionComponent());
|
||||
bullet.addComponent(new VelocityComponent());
|
||||
});
|
||||
```
|
||||
|
||||
**应用场景:**
|
||||
- 生成大量子弹/粒子
|
||||
- 加载关卡时创建大量实体
|
||||
- 清理场景时删除大量实体
|
||||
|
||||
## 性能建议
|
||||
|
||||
### 什么时候使用这些优化?
|
||||
|
||||
| 实体数量 | 推荐配置 | 说明 |
|
||||
|---------|---------|------|
|
||||
| < 1,000 | 默认配置 | 简单场景,不需要特殊优化 |
|
||||
| 1,000 - 10,000 | 启用组件索引 | 中等规模,索引提升查询速度 |
|
||||
| 10,000 - 50,000 | 启用Archetype | 大规模场景,分组优化 |
|
||||
| > 50,000 | 全部优化 | 超大规模,需要所有优化技术 |
|
||||
|
||||
### 常见使用误区
|
||||
|
||||
**错误:过度优化**
|
||||
```typescript
|
||||
// 不要在小项目中使用所有优化
|
||||
const entityManager = new EntityManager();
|
||||
entityManager.enableAllOptimizations(); // 小项目不需要
|
||||
```
|
||||
|
||||
**正确:按需优化**
|
||||
```typescript
|
||||
// 根据实际需求选择优化
|
||||
if (entityCount > 10000) {
|
||||
entityManager.enableArchetypeSystem();
|
||||
}
|
||||
if (hasFrequentQueries) {
|
||||
entityManager.enableComponentIndex();
|
||||
}
|
||||
```
|
||||
|
||||
## 总结
|
||||
|
||||
这些技术概念可能看起来复杂,但它们解决的都是实际开发中的具体问题:
|
||||
|
||||
1. **ECS架构** - 让代码更灵活、可维护
|
||||
2. **组件索引** - 让查询更快速
|
||||
3. **Archetype系统** - 让批量操作更高效
|
||||
4. **脏标记系统** - 让更新更智能
|
||||
5. **事件系统** - 让组件间通信更安全
|
||||
6. **实体管理** - 让大规模场景成为可能
|
||||
|
||||
从简单的场景开始,随着项目复杂度增加,逐步引入这些优化技术。
|
||||
|
||||
## 框架类型系统
|
||||
|
||||
### TypeScript接口设计
|
||||
|
||||
ECS框架采用了精简的TypeScript接口设计,提供类型安全保障的同时保持实现的灵活性。
|
||||
|
||||
#### 核心接口
|
||||
|
||||
**IComponent接口**
|
||||
```typescript
|
||||
interface IComponent {
|
||||
readonly id: number;
|
||||
enabled: boolean;
|
||||
updateOrder: number;
|
||||
|
||||
onAddedToEntity(): void;
|
||||
onRemovedFromEntity(): void;
|
||||
onEnabled(): void;
|
||||
onDisabled(): void;
|
||||
update(): void;
|
||||
}
|
||||
```
|
||||
- 定义所有组件的基本契约
|
||||
- Component基类实现此接口
|
||||
- 确保组件生命周期方法的一致性
|
||||
|
||||
**ISystemBase接口**
|
||||
```typescript
|
||||
interface ISystemBase {
|
||||
readonly systemName: string;
|
||||
readonly entities: readonly any[];
|
||||
updateOrder: number;
|
||||
enabled: boolean;
|
||||
|
||||
initialize(): void;
|
||||
update(): void;
|
||||
lateUpdate?(): void;
|
||||
}
|
||||
```
|
||||
- 为EntitySystem类提供类型约束
|
||||
- 定义系统的核心执行方法
|
||||
- 支持可选的延迟更新
|
||||
|
||||
**IEventBus接口**
|
||||
```typescript
|
||||
interface IEventBus {
|
||||
emit<T>(eventType: string, data: T): void;
|
||||
emitAsync<T>(eventType: string, data: T): Promise<void>;
|
||||
on<T>(eventType: string, handler: (data: T) => void, config?: IEventListenerConfig): string;
|
||||
// ... 其他事件方法
|
||||
}
|
||||
```
|
||||
- 提供类型安全的事件系统契约
|
||||
- 支持同步和异步事件处理
|
||||
- EventBus类完整实现此接口
|
||||
|
||||
#### 事件数据接口
|
||||
|
||||
**事件数据层次结构**
|
||||
```typescript
|
||||
// 基础事件数据
|
||||
interface IEventData {
|
||||
timestamp: number;
|
||||
source?: string;
|
||||
eventId?: string;
|
||||
}
|
||||
|
||||
// 实体相关事件
|
||||
interface IEntityEventData extends IEventData {
|
||||
entityId: number;
|
||||
entityName?: string;
|
||||
entityTag?: string;
|
||||
}
|
||||
|
||||
// 组件相关事件
|
||||
interface IComponentEventData extends IEntityEventData {
|
||||
componentType: string;
|
||||
component?: IComponent;
|
||||
}
|
||||
```
|
||||
- 清晰的继承层次
|
||||
- 类型安全的事件数据传递
|
||||
- 便于事件处理器的实现
|
||||
|
||||
#### 类型别名
|
||||
|
||||
**ComponentType<T>**
|
||||
```typescript
|
||||
type ComponentType<T extends IComponent = IComponent> = new (...args: any[]) => T;
|
||||
```
|
||||
- 用于类型安全的组件操作
|
||||
- 支持泛型约束
|
||||
- 广泛用于实体和查询系统
|
||||
|
||||
### 设计原则
|
||||
|
||||
#### 1. 接口简化原则
|
||||
- 只保留实际使用的接口
|
||||
- 移除了未使用的复杂接口(如IEntityManager、IEntityQueryBuilder等)
|
||||
- 减少认知负担,提高开发效率
|
||||
|
||||
#### 2. 实现灵活性原则
|
||||
- 接口作为类型约束而非强制实现
|
||||
- 允许具体类有更丰富的实现
|
||||
- 保持向后兼容性
|
||||
|
||||
#### 3. 类型安全原则
|
||||
- 编译时类型检查
|
||||
- 泛型支持提供精确的类型推断
|
||||
- 事件系统的完整类型安全
|
||||
|
||||
### 使用指南
|
||||
|
||||
#### 在项目中使用接口
|
||||
```typescript
|
||||
// 作为类型约束
|
||||
function processComponent<T extends IComponent>(component: T) {
|
||||
if (component.enabled) {
|
||||
component.update();
|
||||
}
|
||||
}
|
||||
|
||||
// 作为参数类型
|
||||
function registerSystem(system: ISystemBase) {
|
||||
scene.addEntityProcessor(system);
|
||||
}
|
||||
|
||||
// 作为泛型约束
|
||||
function getComponent<T extends IComponent>(type: ComponentType<T>): T | null {
|
||||
return entity.getComponent(type);
|
||||
}
|
||||
```
|
||||
|
||||
#### 扩展框架接口
|
||||
```typescript
|
||||
// 如果需要扩展组件接口
|
||||
interface IAdvancedComponent extends IComponent {
|
||||
priority: number;
|
||||
category: string;
|
||||
}
|
||||
|
||||
class AdvancedComponent extends Component implements IAdvancedComponent {
|
||||
public priority: number = 0;
|
||||
public category: string = "default";
|
||||
|
||||
// 实现基础接口方法
|
||||
}
|
||||
```
|
||||
|
||||
### 接口维护
|
||||
|
||||
当前的接口设计已经过精心清理,包含:
|
||||
- **12个核心接口** - 涵盖组件、系统、事件等核心概念
|
||||
- **0个冗余接口** - 移除了所有未使用的接口定义
|
||||
- **完整的类型覆盖** - 为所有主要功能提供类型支持
|
||||
|
||||
这种设计确保了框架的类型安全性,同时保持了代码的简洁性和可维护性。

# 核心 API 参考
|
||||
|
||||
本文档详细介绍 ECS Framework 的核心 API 和使用方法。
|
||||
|
||||
> 🤔 **不熟悉ECS概念?** 建议先阅读 [技术概念详解](concepts-explained.md) 了解ECS架构基础和性能优化原理
|
||||
|
||||
## ECS 架构概述
|
||||
|
||||
ECS 架构将传统的面向对象设计分解为三个核心部分:
|
||||
|
||||
- **Entity(实体)** - 游戏世界中的对象,包含基本属性如位置、旋转、缩放
|
||||
- **Component(组件)** - 包含数据和行为的功能模块
|
||||
- **System(系统)** - 处理实体集合的逻辑处理单元
|
||||
|
||||
## Core(核心)
|
||||
|
||||
Core 是框架的核心管理类,负责游戏的生命周期管理。
|
||||
|
||||
### 创建和配置
|
||||
|
||||
```typescript
|
||||
import { Core, ICoreConfig } from '@esengine/ecs-framework';
|
||||
|
||||
// 创建核心实例(使用配置对象 - 推荐)
|
||||
const config: ICoreConfig = {
|
||||
debug: true, // 启用调试模式
|
||||
enableEntitySystems: true, // 启用实体系统
|
||||
debugConfig: { // 可选:远程调试配置
|
||||
enabled: true,
|
||||
websocketUrl: 'ws://localhost:8080',
|
||||
autoReconnect: true,
|
||||
updateInterval: 1000,
|
||||
channels: {
|
||||
entities: true,
|
||||
systems: true,
|
||||
performance: true,
|
||||
components: true,
|
||||
scenes: true
|
||||
}
|
||||
}
|
||||
};
|
||||
const core = Core.create(config);
|
||||
|
||||
// 简化创建(向后兼容)
|
||||
const core1 = Core.create(true); // 调试模式
|
||||
const core2 = Core.create(false); // 发布模式
|
||||
const core3 = Core.create(); // 默认调试模式
|
||||
```
|
||||
|
||||
### 事件系统
|
||||
|
||||
```typescript
|
||||
import { EntityManager, ECSEventType } from '@esengine/ecs-framework';
|
||||
|
||||
// 获取EntityManager的事件系统
|
||||
const entityManager = new EntityManager();
|
||||
const eventBus = entityManager.eventBus;
|
||||
|
||||
// 监听实体事件
|
||||
eventBus.onEntityCreated((data) => {
|
||||
console.log(`实体创建: ${data.entityName}`);
|
||||
});
|
||||
|
||||
eventBus.onComponentAdded((data) => {
|
||||
console.log(`组件添加: ${data.componentType}`);
|
||||
});
|
||||
|
||||
// 发送自定义事件
|
||||
eventBus.emit("customEvent", { data: "value" });
|
||||
|
||||
// 使用事件装饰器(推荐)
|
||||
import { EventHandler } from '@esengine/ecs-framework';
|
||||
|
||||
class GameSystem {
|
||||
@EventHandler('entity:died')
|
||||
onEntityDied(data: any) {
|
||||
console.log('实体死亡:', data);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 定时器系统
|
||||
|
||||
```typescript
|
||||
// 延迟执行
|
||||
Core.schedule(2.0, false, this, (timer) => {
|
||||
console.log("2秒后执行");
|
||||
});
|
||||
|
||||
// 重复执行
|
||||
Core.schedule(1.0, true, this, (timer) => {
|
||||
console.log("每秒执行一次");
|
||||
});
|
||||
```
|
||||
|
||||
## Scene(场景)
|
||||
|
||||
场景是游戏世界的容器,管理实体和系统的生命周期。
|
||||
|
||||
### 创建和使用场景
|
||||
|
||||
```typescript
|
||||
import { Scene } from '@esengine/ecs-framework';
|
||||
|
||||
// 创建场景
|
||||
const scene = new Scene();
|
||||
scene.name = "GameScene";
|
||||
|
||||
// 设置为当前场景
|
||||
Core.scene = scene;
|
||||
|
||||
// 场景生命周期
|
||||
scene.begin(); // 开始场景
|
||||
scene.update(); // 更新场景
|
||||
scene.end(); // 结束场景
|
||||
```
|
||||
|
||||
### 批量实体管理
|
||||
|
||||
```typescript
|
||||
// 批量创建实体 - 高性能
|
||||
const entities = scene.createEntities(1000, "Enemy");
|
||||
|
||||
// 批量添加实体(延迟缓存清理)
|
||||
entities.forEach(entity => {
|
||||
scene.addEntity(entity, false); // 延迟清理
|
||||
});
|
||||
scene.querySystem.clearCache(); // 手动清理缓存
|
||||
|
||||
// 获取性能统计
|
||||
const stats = scene.getStats();
|
||||
console.log(`实体数量: ${stats.entityCount}`);
|
||||
```
|
||||
|
||||
## Entity(实体)
|
||||
|
||||
实体是游戏世界中的基本对象,包含位置、旋转、缩放等基本属性。
|
||||
|
||||
### 实体的基本属性
|
||||
|
||||
```typescript
|
||||
const entity = scene.createEntity("MyEntity");
|
||||
|
||||
// 标签(用于分类)
|
||||
entity.tag = 1;
|
||||
|
||||
// 启用状态
|
||||
entity.enabled = true;
|
||||
|
||||
// 活跃状态
|
||||
entity.active = true;
|
||||
|
||||
// 更新顺序
|
||||
entity.updateOrder = 10;
|
||||
|
||||
// 注意:框架专注于ECS架构,不提供Transform相关功能
|
||||
// 位置、旋转、缩放等Transform功能需要通过组件实现
|
||||
class TransformComponent extends Component {
|
||||
public x: number = 0;
|
||||
public y: number = 0;
|
||||
public rotation: number = 0;
|
||||
public scaleX: number = 1;
|
||||
public scaleY: number = 1;
|
||||
}
|
||||
|
||||
// 使用Transform组件
|
||||
const transform = entity.addComponent(new TransformComponent());
|
||||
transform.x = 100;
|
||||
transform.y = 200;
|
||||
transform.rotation = Math.PI / 4;
|
||||
```
|
||||
|
||||
### 实体层级关系
|
||||
|
||||
```typescript
|
||||
// 添加子实体
|
||||
const parent = scene.createEntity("Parent");
|
||||
const child = scene.createEntity("Child");
|
||||
parent.addChild(child);
|
||||
|
||||
// 获取父实体
|
||||
const parentEntity = child.parent;
|
||||
|
||||
// 获取所有子实体
|
||||
const children = parent.children;
|
||||
|
||||
// 查找子实体
|
||||
const foundChild = parent.findChild("Child");
|
||||
|
||||
// 按标签查找子实体
|
||||
const taggedChildren = parent.findChildrenByTag(1);
|
||||
|
||||
// 移除子实体
|
||||
parent.removeChild(child);
|
||||
|
||||
// 移除所有子实体
|
||||
parent.removeAllChildren();
|
||||
```
|
||||
|
||||
### 实体生命周期
|
||||
|
||||
```typescript
|
||||
// 检查实体是否被销毁
|
||||
if (!entity.isDestroyed) {
|
||||
// 实体仍然有效
|
||||
}
|
||||
|
||||
// 销毁实体
|
||||
entity.destroy();
|
||||
|
||||
// 获取实体调试信息
|
||||
const debugInfo = entity.getDebugInfo();
|
||||
console.log(debugInfo);
|
||||
```
|
||||
|
||||
## Component(组件)
|
||||
|
||||
组件包含数据和行为,定义了实体的特性和能力。
|
||||
|
||||
### 创建组件
|
||||
|
||||
```typescript
|
||||
import { Component } from '@esengine/ecs-framework';
|
||||
|
||||
class HealthComponent extends Component {
|
||||
public maxHealth: number = 100;
|
||||
public currentHealth: number = 100;
|
||||
|
||||
public takeDamage(damage: number) {
|
||||
this.currentHealth -= damage;
|
||||
if (this.currentHealth <= 0) {
|
||||
this.entity.destroy();
|
||||
}
|
||||
}
|
||||
|
||||
public heal(amount: number) {
|
||||
this.currentHealth = Math.min(this.maxHealth, this.currentHealth + amount);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 组件生命周期
|
||||
|
||||
```typescript
|
||||
class MyComponent extends Component {
|
||||
public onAddedToEntity() {
|
||||
// 组件被添加到实体时调用
|
||||
console.log("组件已添加到实体:", this.entity.name);
|
||||
}
|
||||
|
||||
public onRemovedFromEntity() {
|
||||
// 组件从实体移除时调用
|
||||
console.log("组件已从实体移除");
|
||||
}
|
||||
|
||||
public onEnabled() {
|
||||
// 组件启用时调用
|
||||
console.log("组件已启用");
|
||||
}
|
||||
|
||||
public onDisabled() {
|
||||
// 组件禁用时调用
|
||||
console.log("组件已禁用");
|
||||
}
|
||||
|
||||
public update() {
|
||||
// 每帧更新(如果组件启用)
|
||||
console.log("组件更新");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 组件管理
|
||||
|
||||
```typescript
|
||||
// 添加组件
|
||||
const health = entity.addComponent(new HealthComponent());
|
||||
|
||||
// 创建并添加组件
|
||||
const movement = entity.createComponent(MovementComponent, 200); // 传递构造参数
|
||||
|
||||
// 获取组件
|
||||
const healthComp = entity.getComponent(HealthComponent);
|
||||
|
||||
// 检查组件是否存在
|
||||
if (entity.hasComponent(HealthComponent)) {
|
||||
// 处理逻辑
|
||||
}
|
||||
|
||||
// 获取或创建组件
|
||||
const weapon = entity.getOrCreateComponent(WeaponComponent);
|
||||
|
||||
// 获取多个同类型组件
|
||||
const allHealthComps = entity.getComponents(HealthComponent);
|
||||
|
||||
// 移除组件
|
||||
entity.removeComponent(healthComp);
|
||||
|
||||
// 按类型移除组件
|
||||
entity.removeComponentByType(HealthComponent);
|
||||
|
||||
// 移除所有组件
|
||||
entity.removeAllComponents();
|
||||
```
|
||||
|
||||
### 组件对象池优化
|
||||
|
||||
```typescript
|
||||
import { Component, ComponentPoolManager } from '@esengine/ecs-framework';
|
||||
|
||||
class BulletComponent extends Component {
|
||||
public damage: number = 10;
|
||||
public speed: number = 300;
|
||||
|
||||
// 对象池重置方法
|
||||
public reset() {
|
||||
this.damage = 10;
|
||||
this.speed = 300;
|
||||
}
|
||||
}
|
||||
|
||||
// 注册组件池
|
||||
ComponentPoolManager.getInstance().registerPool(
|
||||
'BulletComponent',
|
||||
() => new BulletComponent(),
|
||||
(bullet) => bullet.reset(),
|
||||
1000
|
||||
);
|
||||
|
||||
// 使用对象池获取组件
|
||||
const bullet = ComponentPoolManager.getInstance().acquireComponent('BulletComponent');
|
||||
if (bullet) {
|
||||
entity.addComponent(bullet);
|
||||
}
|
||||
|
||||
// 释放组件回对象池
|
||||
ComponentPoolManager.getInstance().releaseComponent('BulletComponent', bullet);
|
||||
|
||||
// 预热所有组件池
|
||||
ComponentPoolManager.getInstance().prewarmAll(100);
|
||||
|
||||
// 获取池统计
|
||||
const stats = ComponentPoolManager.getInstance().getPoolStats();
|
||||
console.log('组件池统计:', stats);
|
||||
```
|
||||
|
||||
## Scene(场景)
|
||||
|
||||
场景是实体和系统的容器,管理游戏世界的状态。
|
||||
|
||||
### 场景生命周期
|
||||
|
||||
```typescript
|
||||
import { Scene } from '@esengine/ecs-framework';
|
||||
|
||||
class GameScene extends Scene {
|
||||
public initialize() {
|
||||
// 场景初始化,创建实体和系统
|
||||
this.setupEntities();
|
||||
this.setupSystems();
|
||||
}
|
||||
|
||||
public onStart() {
|
||||
// 场景开始运行时调用
|
||||
console.log("场景开始");
|
||||
}
|
||||
|
||||
public unload() {
|
||||
// 场景卸载时调用
|
||||
console.log("场景卸载");
|
||||
}
|
||||
|
||||
private setupEntities() {
|
||||
const player = this.createEntity("Player");
|
||||
player.addComponent(new PlayerComponent());
|
||||
}
|
||||
|
||||
private setupSystems() {
|
||||
this.addEntityProcessor(new MovementSystem());
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 实体管理
|
||||
|
||||
```typescript
|
||||
// 创建实体
|
||||
const entity = scene.createEntity("MyEntity");
|
||||
|
||||
// 添加现有实体
|
||||
scene.addEntity(entity);
|
||||
|
||||
// 查找实体
|
||||
const player = scene.findEntity("Player");
|
||||
const entityById = scene.findEntityById(123);
|
||||
const entitiesByTag = scene.findEntitiesByTag(1);
|
||||
|
||||
// 销毁所有实体
|
||||
scene.destroyAllEntities();
|
||||
|
||||
// 获取场景统计信息
|
||||
const stats = scene.getStats();
|
||||
console.log("实体数量:", stats.entityCount);
|
||||
console.log("系统数量:", stats.processorCount);
|
||||
```
|
||||
|
||||
## System(系统)
|
||||
|
||||
系统处理实体集合,实现游戏的核心逻辑。
|
||||
|
||||
### EntitySystem
|
||||
|
||||
最常用的系统类型,处理实体集合:
|
||||
|
||||
```typescript
|
||||
import { EntitySystem, Entity, Matcher } from '@esengine/ecs-framework';
|
||||
|
||||
class MovementSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.empty().all(MovementComponent));
|
||||
}
|
||||
|
||||
protected process(entities: Entity[]) {
|
||||
for (const entity of entities) {
|
||||
const movement = entity.getComponent(MovementComponent);
|
||||
if (movement) {
|
||||
movement.update();
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### ProcessingSystem
|
||||
|
||||
定期处理的系统:
|
||||
|
||||
```typescript
|
||||
import { ProcessingSystem, Time, Matcher } from '@esengine/ecs-framework';
|
||||
|
||||
class HealthRegenerationSystem extends ProcessingSystem {
|
||||
constructor() {
|
||||
super(Matcher.empty().all(HealthComponent));
|
||||
}
|
||||
|
||||
public processSystem() {
|
||||
// ProcessingSystem不处理具体实体,而是执行全局逻辑
|
||||
// 如果需要处理实体,应该使用EntitySystem
|
||||
this.regenerateAllPlayerHealth();
|
||||
}
|
||||
|
||||
private regenerateAllPlayerHealth() {
|
||||
// 通过场景查找所有玩家实体并恢复生命值
|
||||
const players = this.scene.findEntitiesByTag(PlayerTag);
|
||||
for (const player of players) {
|
||||
const health = player.getComponent(HealthComponent);
|
||||
if (health && health.currentHealth < health.maxHealth) {
|
||||
health.currentHealth += 10 * Time.deltaTime;
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### IntervalSystem
|
||||
|
||||
按时间间隔执行的系统:
|
||||
|
||||
```typescript
|
||||
import { IntervalSystem, Matcher } from '@esengine/ecs-framework';
|
||||
|
||||
class SpawnSystem extends IntervalSystem {
|
||||
constructor() {
|
||||
// IntervalSystem需要Matcher和间隔时间
|
||||
super(Matcher.empty(), 3.0); // 每3秒执行一次
|
||||
}
|
||||
|
||||
protected process(entities: Entity[]) {
|
||||
// 生成敌人
|
||||
const enemy = this.scene.createEntity("Enemy");
|
||||
enemy.addComponent(new EnemyComponent());
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### PassiveSystem
|
||||
|
||||
被动系统,不自动处理实体:
|
||||
|
||||
```typescript
|
||||
import { PassiveSystem, Matcher } from '@esengine/ecs-framework';
|
||||
|
||||
class CollisionSystem extends PassiveSystem {
|
||||
constructor() {
|
||||
super(Matcher.empty());
|
||||
}
|
||||
|
||||
public checkCollisions() {
|
||||
// 手动调用的碰撞检测逻辑
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Time(时间)
|
||||
|
||||
时间管理工具类,提供游戏时间相关功能:
|
||||
|
||||
```typescript
|
||||
import { Time } from '@esengine/ecs-framework';
|
||||
|
||||
// 获取时间信息
|
||||
console.log("帧时间:", Time.deltaTime);
|
||||
console.log("总时间:", Time.totalTime);
|
||||
console.log("帧数:", Time.frameCount);
|
||||
console.log("时间缩放:", Time.timeScale);
|
||||
|
||||
// 设置时间缩放(慢动作效果)
|
||||
Time.timeScale = 0.5;
|
||||
|
||||
// 检查时间间隔
|
||||
if (Time.checkEvery(1.0, lastCheckTime)) {
|
||||
// 每秒执行一次
|
||||
}
|
||||
```
|
||||
|
||||
## 性能监控
|
||||
|
||||
框架内置性能监控工具:
|
||||
|
||||
```typescript
|
||||
import { PerformanceMonitor } from '@esengine/ecs-framework';
|
||||
|
||||
// 获取性能监控实例
|
||||
const monitor = PerformanceMonitor.instance;
|
||||
|
||||
// 查看性能数据
|
||||
console.log("平均FPS:", monitor.averageFPS);
|
||||
console.log("最小FPS:", monitor.minFPS);
|
||||
console.log("最大FPS:", monitor.maxFPS);
|
||||
console.log("内存使用:", monitor.memoryUsage);
|
||||
|
||||
// 重置性能数据
|
||||
monitor.reset();
|
||||
```
|
||||
|
||||
## 对象池
|
||||
|
||||
内存管理优化工具:
|
||||
|
||||
```typescript
|
||||
import { Pool, IPoolable } from '@esengine/ecs-framework';
|
||||
|
||||
// 定义可池化的对象(需要实现IPoolable接口)
|
||||
class Bullet implements IPoolable {
|
||||
public x: number = 0;
|
||||
public y: number = 0;
|
||||
public speed: number = 0;
|
||||
|
||||
// 重置对象状态,准备重用
|
||||
public reset(): void {
|
||||
this.x = 0;
|
||||
this.y = 0;
|
||||
this.speed = 0;
|
||||
}
|
||||
}
|
||||
|
||||
// 创建对象池
|
||||
const bulletPool = new Pool<Bullet>(() => new Bullet(), 100);
|
||||
|
||||
// 预热对象池
|
||||
bulletPool.warmUp(20);
|
||||
|
||||
// 使用对象池
|
||||
const bullet = bulletPool.obtain();
|
||||
bullet.x = 100;
|
||||
bullet.y = 200;
|
||||
bullet.speed = 500;
|
||||
|
||||
// 使用完后归还到池中
|
||||
bulletPool.free(bullet);
|
||||
|
||||
// 查看池统计信息
|
||||
console.log(bulletPool.getStats());
|
||||
|
||||
// 清空对象池
|
||||
bulletPool.clear();
|
||||
|
||||
// 使用静态方法(自动管理池)
|
||||
const bullet2 = Pool.obtain(Bullet);
|
||||
Pool.free(Bullet, bullet2);
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 实体设计
|
||||
|
||||
- 实体只包含基本属性,功能通过组件实现
|
||||
- 合理使用实体层级关系
|
||||
- 及时销毁不需要的实体
|
||||
|
||||
### 2. 组件设计
|
||||
|
||||
- 组件保持单一职责
|
||||
- 使用生命周期方法进行初始化和清理
|
||||
- 避免组件间直接依赖
|
||||
|
||||
### 3. 系统设计
|
||||
|
||||
- 系统专注于特定逻辑处理
|
||||
- 合理设置系统更新顺序
|
||||
- 使用被动系统处理特殊逻辑
|
||||
|
||||
### 4. 性能优化
|
||||
|
||||
- 使用对象池减少内存分配
|
||||
- 监控性能数据
|
||||
- 合理使用时间缩放
|
||||
|
||||
## 高级性能优化功能
|
||||
|
||||
### 查询系统优化
|
||||
|
||||
框架内部已集成查询优化,无需手动配置。查询系统会自动使用最优的算法:
|
||||
|
||||
```typescript
|
||||
// 查询系统会自动优化这些操作
|
||||
const movingEntities = scene.querySystem.queryAll(PositionComponent, VelocityComponent);
|
||||
const renderableEntities = scene.querySystem.queryAll(PositionComponent, RenderComponent);
|
||||
|
||||
// 获取查询统计信息
|
||||
const queryStats = scene.querySystem.getStats();
|
||||
console.log('查询统计:', queryStats);
|
||||
```
|
||||
|
||||
### 批量操作API
|
||||
|
||||
```typescript
|
||||
// 批量创建实体 - 最高性能
|
||||
const entities = scene.createEntities(10000, "Bullets");
|
||||
|
||||
// 批量查询优化
|
||||
const movingEntities = scene.querySystem.queryAll(PositionComponent, VelocityComponent).entities;
|
||||
```
|
||||
|
||||
## 总结
|
||||
|
||||
ECS Framework 提供了完整的实体组件系统架构:
|
||||
|
||||
- **Core** 管理游戏生命周期和全局功能
|
||||
- **Entity** 作为游戏对象的基础容器
|
||||
- **Component** 实现具体的功能模块,支持对象池优化
|
||||
- **System** 处理游戏逻辑
|
||||
- **Scene** 管理游戏世界状态,支持批量操作
|
||||
- **高级优化** 位掩码优化器、组件对象池、批量操作等
|
||||
|
||||

# Quick Start
|
||||
|
||||
This guide will help you get started with ECS Framework, from installation to creating your first ECS application.
|
||||
|
||||
## Installation
|
||||
|
||||
### NPM Installation
|
||||
|
||||
```bash
|
||||
# Using npm
|
||||
npm install @esengine/ecs-framework
|
||||
```
|
||||
|
||||
## Initialize Core
|
||||
|
||||
### Basic Initialization
|
||||
|
||||
The core of ECS Framework is the `Core` class, a singleton that manages the entire framework lifecycle.
|
||||
|
||||
```typescript
|
||||
import { Core } from '@esengine/ecs-framework'
|
||||
|
||||
// Method 1: Using config object (recommended)
|
||||
const core = Core.create({
|
||||
debug: true, // Enable debug mode for detailed logs and performance monitoring
|
||||
debugConfig: { // Optional: Advanced debug configuration
|
||||
enabled: false, // Whether to enable WebSocket debug server
|
||||
websocketUrl: 'ws://localhost:8080',
|
||||
debugFrameRate: 30, // Debug data send frame rate
|
||||
channels: {
|
||||
entities: true,
|
||||
systems: true,
|
||||
performance: true,
|
||||
components: true,
|
||||
scenes: true
|
||||
}
|
||||
}
|
||||
});
|
||||
|
||||
// Method 2: Simplified creation (backward compatible)
|
||||
const core = Core.create(true); // Equivalent to { debug: true }
|
||||
|
||||
// Method 3: Production environment configuration
|
||||
const core = Core.create({
|
||||
debug: false // Disable debug in production
|
||||
});
|
||||
```
|
||||
|
||||
### Core Configuration Details
|
||||
|
||||
```typescript
|
||||
interface ICoreConfig {
|
||||
/** Enable debug mode - affects log level and performance monitoring */
|
||||
debug?: boolean;
|
||||
|
||||
/** Advanced debug configuration - for dev tools integration */
|
||||
debugConfig?: {
|
||||
enabled: boolean; // Enable debug server
|
||||
websocketUrl: string; // WebSocket server URL
|
||||
autoReconnect?: boolean; // Auto reconnect
|
||||
debugFrameRate?: 60 | 30 | 15; // Debug data send frame rate
|
||||
channels: { // Data channel configuration
|
||||
entities: boolean; // Entity data
|
||||
systems: boolean; // System data
|
||||
performance: boolean; // Performance data
|
||||
components: boolean; // Component data
|
||||
scenes: boolean; // Scene data
|
||||
};
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### Core Instance Management
|
||||
|
||||
Core uses singleton pattern, accessible via static property after creation:
|
||||
|
||||
```typescript
|
||||
// Create instance
|
||||
const core = Core.create(true);
|
||||
|
||||
// Get created instance
|
||||
const instance = Core.Instance; // Returns current instance, null if not created
|
||||
```
|
||||
|
||||
### Game Loop Integration
|
||||
|
||||
**Important**: Before creating entities and systems, you need to understand how to integrate ECS Framework into your game engine.
|
||||
|
||||
`Core.update(deltaTime)` is the framework heartbeat, must be called every frame. It handles:
|
||||
- Updating the built-in Time class
|
||||
- Updating all global managers (timers, object pools, etc.)
|
||||
- Updating all entity systems in all scenes
|
||||
- Processing entity creation and destruction
|
||||
- Collecting performance data (in debug mode)
|
||||
|
||||
See engine integration examples: [Game Engine Integration](#game-engine-integration)
|
||||
|
||||
## Create Your First ECS Application
|
||||
|
||||
### 1. Define Components
|
||||
|
||||
Components are pure data containers that store entity state:
|
||||
|
||||
```typescript
|
||||
import { Component, ECSComponent } from '@esengine/ecs-framework'
|
||||
|
||||
// Position component
|
||||
@ECSComponent('Position')
|
||||
class Position extends Component {
|
||||
x: number = 0
|
||||
y: number = 0
|
||||
|
||||
constructor(x: number = 0, y: number = 0) {
|
||||
super()
|
||||
this.x = x
|
||||
this.y = y
|
||||
}
|
||||
}
|
||||
|
||||
// Velocity component
|
||||
@ECSComponent('Velocity')
|
||||
class Velocity extends Component {
|
||||
dx: number = 0
|
||||
dy: number = 0
|
||||
|
||||
constructor(dx: number = 0, dy: number = 0) {
|
||||
super()
|
||||
this.dx = dx
|
||||
this.dy = dy
|
||||
}
|
||||
}
|
||||
|
||||
// Sprite component
|
||||
@ECSComponent('Sprite')
|
||||
class Sprite extends Component {
|
||||
texture: string = ''
|
||||
width: number = 32
|
||||
height: number = 32
|
||||
|
||||
constructor(texture: string, width: number = 32, height: number = 32) {
|
||||
super()
|
||||
this.texture = texture
|
||||
this.width = width
|
||||
this.height = height
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Create Entity Systems
|
||||
|
||||
Systems contain game logic and process entities with specific components. ECS Framework provides Matcher-based entity filtering:
|
||||
|
||||
```typescript
|
||||
import { EntitySystem, Matcher, Time, ECSSystem } from '@esengine/ecs-framework'
|
||||
|
||||
// Movement system - handles position and velocity
|
||||
@ECSSystem('MovementSystem')
|
||||
class MovementSystem extends EntitySystem {
|
||||
|
||||
constructor() {
|
||||
// Use Matcher to define target entities: must have both Position and Velocity
|
||||
super(Matcher.empty().all(Position, Velocity))
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// process method receives all matching entities
|
||||
for (const entity of entities) {
|
||||
const position = entity.getComponent(Position)!
|
||||
const velocity = entity.getComponent(Velocity)!
|
||||
|
||||
// Update position (using framework's Time class)
|
||||
position.x += velocity.dx * Time.deltaTime
|
||||
position.y += velocity.dy * Time.deltaTime
|
||||
|
||||
// Boundary check example
|
||||
if (position.x < 0) position.x = 0
|
||||
if (position.y < 0) position.y = 0
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// Render system - handles visible objects
|
||||
@ECSSystem('RenderSystem')
|
||||
class RenderSystem extends EntitySystem {
|
||||
|
||||
constructor() {
|
||||
// Must have Position and Sprite, optional Velocity (for direction)
|
||||
super(Matcher.empty().all(Position, Sprite).any(Velocity))
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const position = entity.getComponent(Position)!
|
||||
const sprite = entity.getComponent(Sprite)!
|
||||
const velocity = entity.getComponent(Velocity) // May be null
|
||||
|
||||
// Flip sprite based on velocity direction (optional logic)
|
||||
let flipX = false
|
||||
if (velocity && velocity.dx < 0) {
|
||||
flipX = true
|
||||
}
|
||||
|
||||
// Render logic (pseudocode here)
|
||||
this.drawSprite(sprite.texture, position.x, position.y, sprite.width, sprite.height, flipX)
|
||||
}
|
||||
}
|
||||
|
||||
private drawSprite(texture: string, x: number, y: number, width: number, height: number, flipX: boolean = false) {
|
||||
// Actual render implementation depends on your game engine
|
||||
const direction = flipX ? '<-' : '->'
|
||||
console.log(`Render ${texture} at (${x.toFixed(1)}, ${y.toFixed(1)}) direction: ${direction}`)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
### 3. Create Scene
|
||||
|
||||
Recommended to extend Scene class for custom scenes:
|
||||
|
||||
```typescript
|
||||
import { Scene } from '@esengine/ecs-framework'
|
||||
|
||||
// Recommended: Extend Scene for custom scene
|
||||
class GameScene extends Scene {
|
||||
|
||||
initialize(): void {
|
||||
// Scene initialization logic
|
||||
this.name = "MainScene";
|
||||
|
||||
// Add systems to scene
|
||||
this.addSystem(new MovementSystem());
|
||||
this.addSystem(new RenderSystem());
|
||||
}
|
||||
|
||||
onStart(): void {
|
||||
// Logic when scene starts running
|
||||
console.log("Game scene started");
|
||||
}
|
||||
|
||||
unload(): void {
|
||||
// Cleanup logic when scene unloads
|
||||
console.log("Game scene unloaded");
|
||||
}
|
||||
}
|
||||
|
||||
// Create and set scene
|
||||
const gameScene = new GameScene();
|
||||
Core.setScene(gameScene);
|
||||
```
|
||||
|
||||
### 4. Create Entities
|
||||
|
||||
```typescript
|
||||
// Create player entity
|
||||
const player = gameScene.createEntity("Player");
|
||||
player.addComponent(new Position(100, 100));
|
||||
player.addComponent(new Velocity(50, 30)); // Move 50px/sec (x), 30px/sec (y)
|
||||
player.addComponent(new Sprite("player.png", 64, 64));
|
||||
```
|
||||
|
||||
## Scene Management
|
||||
|
||||
Core has built-in scene management, very simple to use:
|
||||
|
||||
```typescript
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
|
||||
// Initialize Core
|
||||
Core.create({ debug: true });
|
||||
|
||||
// Create and set scene
|
||||
class GameScene extends Scene {
|
||||
initialize(): void {
|
||||
this.name = "GamePlay";
|
||||
this.addSystem(new MovementSystem());
|
||||
this.addSystem(new RenderSystem());
|
||||
}
|
||||
}
|
||||
|
||||
const gameScene = new GameScene();
|
||||
Core.setScene(gameScene);
|
||||
|
||||
// Game loop (auto-updates scene)
|
||||
function gameLoop(deltaTime: number) {
|
||||
Core.update(deltaTime); // Auto-updates global services and scene
|
||||
}
|
||||
|
||||
// Switch scenes
|
||||
Core.loadScene(new MenuScene()); // Delayed switch (next frame)
|
||||
Core.setScene(new GameScene()); // Immediate switch
|
||||
|
||||
// Access current scene
|
||||
const currentScene = Core.scene;
|
||||
|
||||
// Using fluent API
|
||||
const player = Core.ecsAPI?.createEntity('Player')
|
||||
.addComponent(Position, 100, 100)
|
||||
.addComponent(Velocity, 50, 0);
|
||||
```
|
||||
|
||||
### Advanced: Using WorldManager for Multi-World
|
||||
|
||||
Only for complex server-side applications (MMO game servers, game room systems, etc.):
|
||||
|
||||
```typescript
|
||||
import { Core, WorldManager } from '@esengine/ecs-framework';
|
||||
|
||||
// Initialize Core
|
||||
Core.create({ debug: true });
|
||||
|
||||
// Get WorldManager from service container (Core auto-creates and registers it)
|
||||
const worldManager = Core.services.resolve(WorldManager);
|
||||
|
||||
// Create multiple independent game worlds
|
||||
const room1 = worldManager.createWorld('room_001');
|
||||
const room2 = worldManager.createWorld('room_002');
|
||||
|
||||
// Create scenes in each world
|
||||
const gameScene1 = room1.createScene('game', new GameScene());
|
||||
const gameScene2 = room2.createScene('game', new GameScene());
|
||||
|
||||
// Activate scenes
|
||||
room1.setSceneActive('game', true);
|
||||
room2.setSceneActive('game', true);
|
||||
|
||||
// Game loop (need to manually update worlds)
|
||||
function gameLoop(deltaTime: number) {
|
||||
Core.update(deltaTime); // Update global services
|
||||
worldManager.updateAll(); // Manually update all worlds
|
||||
}
|
||||
```
|
||||
|
||||
## Game Engine Integration
|
||||
|
||||
### Laya Engine Integration
|
||||
|
||||
```typescript
|
||||
import { Stage } from "laya/display/Stage";
|
||||
import { Laya } from "Laya";
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
|
||||
// Initialize Laya
|
||||
Laya.init(800, 600).then(() => {
|
||||
// Initialize ECS
|
||||
Core.create(true);
|
||||
Core.setScene(new GameScene());
|
||||
|
||||
// Start game loop
|
||||
Laya.timer.frameLoop(1, this, () => {
|
||||
const deltaTime = Laya.timer.delta / 1000;
|
||||
Core.update(deltaTime); // Auto-updates global services and scene
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### Cocos Creator Integration
|
||||
|
||||
```typescript
|
||||
import { Component, _decorator } from 'cc';
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
|
||||
const { ccclass } = _decorator;
|
||||
|
||||
@ccclass('ECSGameManager')
|
||||
export class ECSGameManager extends Component {
|
||||
onLoad() {
|
||||
// Initialize ECS
|
||||
Core.create(true);
|
||||
Core.setScene(new GameScene());
|
||||
}
|
||||
|
||||
update(deltaTime: number) {
|
||||
// Auto-updates global services and scene
|
||||
Core.update(deltaTime);
|
||||
}
|
||||
|
||||
onDestroy() {
|
||||
// Cleanup resources
|
||||
Core.destroy();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## Next Steps
|
||||
|
||||
You've successfully created your first ECS application! Next you can:
|
||||
|
||||
- Check the complete [API Documentation](/api/README)
|
||||
- Explore more [practical examples](/examples/)
|
||||
|
||||
## FAQ
|
||||
|
||||
### Why isn't my system executing?
|
||||
|
||||
Ensure:
|
||||
1. System is added to scene: `this.addSystem(system)` (in Scene's initialize method)
|
||||
2. Scene is set: `Core.setScene(scene)`
|
||||
3. Game loop is calling: `Core.update(deltaTime)`
|
||||
|
||||
### How to debug ECS applications?
|
||||
|
||||
Enable debug mode:
|
||||
|
||||
```typescript
|
||||
Core.create({ debug: true })
|
||||
|
||||
// Get debug data
|
||||
const debugData = Core.getDebugData()
|
||||
console.log(debugData)
|
||||
```

# 实体基础指南
|
||||
|
||||
本指南介绍实体(Entity)的基本概念和基础使用方法。
|
||||
|
||||
> 📖 **需要高级实体管理?** 请参考 [EntityManager 指南](entity-manager-example.md) 了解高性能查询和批量操作
|
||||
|
||||
## 实体概述
|
||||
|
||||
实体(Entity)是 ECS 架构中的核心概念之一,它作为组件的容器存在。实体本身不包含游戏逻辑,所有功能都通过添加不同的组件来实现。
|
||||
|
||||
### 实体的特点
|
||||
|
||||
- **轻量级容器**:实体只是组件的载体,不包含具体的游戏逻辑
|
||||
- **唯一标识**:每个实体都有唯一的ID和名称
|
||||
- **层次结构**:支持父子关系,可以构建复杂的实体层次
|
||||
- **高性能查询**:基于位掩码的组件查询系统
|
||||
- **生命周期管理**:完整的创建、更新、销毁流程
|
||||
|
||||
## 创建实体
|
||||
|
||||
### 基本创建方式
|
||||
|
||||
```typescript
|
||||
import { Scene } from '@esengine/ecs-framework';
|
||||
|
||||
// 通过场景创建实体
|
||||
const scene = new Scene();
|
||||
const entity = scene.createEntity("Player");
|
||||
|
||||
console.log(entity.name); // "Player"
|
||||
console.log(entity.id); // 唯一的数字ID
|
||||
```
|
||||
|
||||
### 批量创建实体(推荐)
|
||||
|
||||
```typescript
|
||||
import { Scene } from '@esengine/ecs-framework';
|
||||
|
||||
const scene = new Scene();
|
||||
|
||||
// 批量创建1000个实体 - 高性能
|
||||
const entities = scene.createEntities(1000, "Enemy");
|
||||
|
||||
// 批量配置
|
||||
entities.forEach((entity, index) => {
|
||||
entity.tag = 2; // 敌人标签
|
||||
// 添加组件...
|
||||
});
|
||||
```
|
||||
|
||||
### 使用流式API创建
|
||||
|
||||
```typescript
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
|
||||
// 使用ECS流式API
|
||||
const entity = Core.ecsAPI
|
||||
?.entity("Enemy")
|
||||
.withComponent(new PositionComponent(100, 200))
|
||||
.withComponent(new HealthComponent(50))
|
||||
.withTag(2)
|
||||
.build();
|
||||
```
|
||||
|
||||
## 实体属性
|
||||
|
||||
### 基本属性
|
||||
|
||||
```typescript
|
||||
// 实体名称 - 用于调试和标识
|
||||
entity.name = "Player";
|
||||
|
||||
// 实体ID - 只读,场景内唯一
|
||||
console.log(entity.id); // 例如: 1
|
||||
|
||||
// 标签 - 用于分类和快速查询
|
||||
entity.tag = 1; // 玩家标签
|
||||
entity.tag = 2; // 敌人标签
|
||||
|
||||
// 更新顺序 - 控制实体在系统中的处理优先级
|
||||
entity.updateOrder = 0; // 数值越小优先级越高
|
||||
```
|
||||
|
||||
### 状态控制
|
||||
|
||||
```typescript
|
||||
// 启用状态 - 控制实体是否参与更新和处理
|
||||
entity.enabled = true; // 启用实体
|
||||
entity.enabled = false; // 禁用实体
|
||||
|
||||
// 激活状态 - 控制实体及其子实体的活跃状态
|
||||
entity.active = true; // 激活实体
|
||||
entity.active = false; // 停用实体
|
||||
|
||||
// 检查层次结构中的激活状态
|
||||
if (entity.activeInHierarchy) {
|
||||
// 实体在整个层次结构中都是激活的
|
||||
}
|
||||
|
||||
// 检查销毁状态
|
||||
if (entity.isDestroyed) {
|
||||
// 实体已被销毁
|
||||
}
|
||||
```
|
||||
|
||||
### 更新间隔
|
||||
|
||||
```typescript
|
||||
// 控制实体更新频率
|
||||
entity.updateInterval = 1; // 每帧更新
|
||||
entity.updateInterval = 2; // 每2帧更新一次
|
||||
entity.updateInterval = 5; // 每5帧更新一次
|
||||
```
|
||||
|
||||
## 组件管理
|
||||
|
||||
### 添加组件
|
||||
|
||||
```typescript
|
||||
// 创建并添加组件
|
||||
const healthComponent = entity.addComponent(new HealthComponent(100));
|
||||
|
||||
// 使用工厂方法创建组件
|
||||
const positionComponent = entity.createComponent(PositionComponent, 100, 200);
|
||||
|
||||
// 批量添加组件
|
||||
const components = entity.addComponents([
|
||||
new PositionComponent(0, 0),
|
||||
new VelocityComponent(50, 0),
|
||||
new HealthComponent(100)
|
||||
]);
|
||||
```
|
||||
|
||||
### 获取组件
|
||||
|
||||
```typescript
|
||||
// 获取单个组件
|
||||
const health = entity.getComponent(HealthComponent);
|
||||
if (health) {
|
||||
console.log(`当前生命值: ${health.currentHealth}`);
|
||||
}
|
||||
|
||||
// 获取或创建组件(如果不存在则创建)
|
||||
const position = entity.getOrCreateComponent(PositionComponent, 0, 0);
|
||||
|
||||
// 获取多个同类型组件(如果组件可以重复添加)
|
||||
const allHealthComponents = entity.getComponents(HealthComponent);
|
||||
```
|
||||
|
||||
### 检查组件
|
||||
|
||||
```typescript
|
||||
// 检查是否拥有指定组件
|
||||
if (entity.hasComponent(HealthComponent)) {
|
||||
// 实体拥有生命值组件
|
||||
}
|
||||
|
||||
// 检查组件掩码(高性能)
|
||||
const mask = entity.componentMask;
|
||||
console.log(`组件掩码: ${mask.toString(2)}`); // 二进制表示
|
||||
```
|
||||
|
||||
### 移除组件
|
||||
|
||||
```typescript
|
||||
// 移除指定组件实例
|
||||
const healthComponent = entity.getComponent(HealthComponent);
|
||||
if (healthComponent) {
|
||||
entity.removeComponent(healthComponent);
|
||||
}
|
||||
|
||||
// 按类型移除组件
|
||||
const removedHealth = entity.removeComponentByType(HealthComponent);
|
||||
|
||||
// 批量移除组件
|
||||
const removedComponents = entity.removeComponentsByTypes([
|
||||
HealthComponent,
|
||||
VelocityComponent
|
||||
]);
|
||||
|
||||
// 移除所有组件
|
||||
entity.removeAllComponents();
|
||||
```
|
||||
|
||||
## 层次结构管理
|
||||
|
||||
### 父子关系
|
||||
|
||||
```typescript
|
||||
// 创建父子实体
|
||||
const player = scene.createEntity("Player");
|
||||
const weapon = scene.createEntity("Weapon");
|
||||
const shield = scene.createEntity("Shield");
|
||||
|
||||
// 添加子实体
|
||||
player.addChild(weapon);
|
||||
player.addChild(shield);
|
||||
|
||||
// 获取父实体
|
||||
console.log(weapon.parent === player); // true
|
||||
|
||||
// 获取所有子实体
|
||||
const children = player.children;
|
||||
console.log(children.length); // 2
|
||||
|
||||
// 获取子实体数量
|
||||
console.log(player.childCount); // 2
|
||||
```
|
||||
|
||||
### 查找子实体
|
||||
|
||||
```typescript
|
||||
// 按名称查找子实体
|
||||
const weapon = player.findChild("Weapon");
|
||||
|
||||
// 递归查找子实体
|
||||
const deepChild = player.findChild("DeepChild", true);
|
||||
|
||||
// 按标签查找子实体
|
||||
const enemies = player.findChildrenByTag(2); // 查找所有敌人标签的子实体
|
||||
|
||||
// 递归按标签查找
|
||||
const allEnemies = player.findChildrenByTag(2, true);
|
||||
```
|
||||
|
||||
### 层次结构操作
|
||||
|
||||
```typescript
|
||||
// 移除子实体
|
||||
const removed = player.removeChild(weapon);
|
||||
|
||||
// 移除所有子实体
|
||||
player.removeAllChildren();
|
||||
|
||||
// 获取根实体
|
||||
const root = weapon.getRoot();
|
||||
|
||||
// 检查祖先关系
|
||||
if (player.isAncestorOf(weapon)) {
|
||||
// player 是 weapon 的祖先
|
||||
}
|
||||
|
||||
// 检查后代关系
|
||||
if (weapon.isDescendantOf(player)) {
|
||||
// weapon 是 player 的后代
|
||||
}
|
||||
|
||||
// 获取实体在层次结构中的深度
|
||||
const depth = weapon.getDepth(); // 从根实体开始计算的深度
|
||||
```
|
||||
|
||||
### 遍历子实体
|
||||
|
||||
```typescript
|
||||
// 遍历直接子实体
|
||||
player.forEachChild((child, index) => {
|
||||
console.log(`子实体 ${index}: ${child.name}`);
|
||||
});
|
||||
|
||||
// 递归遍历所有子实体
|
||||
player.forEachChild((child, index) => {
|
||||
console.log(`子实体 ${index}: ${child.name} (深度: ${child.getDepth()})`);
|
||||
}, true);
|
||||
```
|
||||
|
||||
## 实体生命周期
|
||||
|
||||
### 更新循环
|
||||
|
||||
```typescript
|
||||
// 手动更新实体(通常由场景自动调用)
|
||||
entity.update();
|
||||
|
||||
// 实体会自动调用所有组件的update方法
|
||||
class MyComponent extends Component {
|
||||
public update(): void {
|
||||
// 组件更新逻辑
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 销毁实体
|
||||
|
||||
```typescript
|
||||
// 销毁实体
|
||||
entity.destroy();
|
||||
|
||||
// 检查是否已销毁
|
||||
if (entity.isDestroyed) {
|
||||
console.log("实体已被销毁");
|
||||
}
|
||||
|
||||
// 销毁实体时会自动:
|
||||
// 1. 移除所有组件
|
||||
// 2. 从父实体中移除
|
||||
// 3. 销毁所有子实体
|
||||
// 4. 从场景中移除
|
||||
```
|
||||

> - **组件索引和缓存** → [技术概念详解](concepts-explained.md)
|
||||
|
||||
## 基础最佳实践
|
||||
|
||||
### 1. 合理使用标签
|
||||
|
||||
```typescript
|
||||
// 定义标签常量
|
||||
const EntityTags = {
|
||||
PLAYER: 1,
|
||||
ENEMY: 2,
|
||||
PROJECTILE: 3,
|
||||
PICKUP: 4
|
||||
} as const;
|
||||
|
||||
// 使用标签进行分类
|
||||
player.tag = EntityTags.PLAYER;
|
||||
enemy.tag = EntityTags.ENEMY;
|
||||
```
|
||||
|
||||
### 2. 正确的销毁处理
|
||||
|
||||
```typescript
|
||||
// 确保正确销毁实体
|
||||
if (!entity.isDestroyed) {
|
||||
entity.destroy(); // 自动移除组件和层次关系
|
||||
}
|
||||
|
||||
// 检查实体状态
|
||||
if (entity.isDestroyed) {
|
||||
return; // 避免操作已销毁的实体
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 组件生命周期
|
||||
|
||||
```typescript
|
||||
// 正确添加组件
|
||||
const health = entity.addComponent(new HealthComponent(100));
|
||||
|
||||
// 安全获取组件
|
||||
const healthComp = entity.getComponent(HealthComponent);
|
||||
if (healthComp && healthComp.currentHealth <= 0) {
|
||||
entity.destroy();
|
||||
}
|
||||
```
|
||||
|
||||
## 常见问题
|
||||
|
||||
### Q: 实体如何实现位置、旋转等变换?
|
||||
|
||||
A: 通过添加相应的组件:
|
||||
|
||||
```typescript
|
||||
class TransformComponent extends Component {
|
||||
public position = { x: 0, y: 0 };
|
||||
public rotation = 0;
|
||||
public scale = { x: 1, y: 1 };
|
||||
}
|
||||
|
||||
entity.addComponent(new TransformComponent());
|
||||
```
|
||||
|
||||
### Q: 实体可以在场景间移动吗?
|
||||
|
||||
A: 不可以。实体与场景绑定,需要在新场景中重新创建。

## 基础用法
|
||||
|
||||
### 创建 EntityManager
|
||||
|
||||
```typescript
|
||||
import { EntityManager, Scene } from '@esengine/ecs-framework';
|
||||
|
||||
// 创建场景和实体管理器
|
||||
const scene = new Scene();
|
||||
const entityManager = new EntityManager();
|
||||
|
||||
// 批量创建实体(使用Scene方法)
|
||||
const enemies = scene.createEntities(50, "Enemy");
|
||||
|
||||
// 为实体添加组件
|
||||
enemies.forEach((enemy, index) => {
|
||||
enemy.addComponent(new PositionComponent(
|
||||
Math.random() * 800,
|
||||
Math.random() * 600
|
||||
));
|
||||
enemy.addComponent(new HealthComponent(100));
|
||||
enemy.addComponent(new VelocityComponent(
|
||||
(Math.random() - 0.5) * 100,
|
||||
(Math.random() - 0.5) * 100
|
||||
));
|
||||
enemy.tag = 2; // 敌人标签
|
||||
});
|
||||
```
|
||||
|
||||
## 查询系统
|
||||
|
||||
### 基础查询
|
||||
|
||||
```typescript
|
||||
// 按组件类型查询
|
||||
const healthEntities = entityManager.getEntitiesWithComponent(HealthComponent);
|
||||
|
||||
// 按标签查询
|
||||
const enemies = entityManager.getEntitiesByTag(2);
|
||||
const players = entityManager.getEntitiesByTag(1);
|
||||
|
||||
// 按名称查询
|
||||
const boss = entityManager.getEntityByName("BossEnemy");
|
||||
|
||||
// 获取所有实体
|
||||
const allEntities = entityManager.getAllEntities();
|
||||
```
|
||||
|
||||
### 流式查询 API
|
||||
|
||||
```typescript
|
||||
// 复杂查询条件
|
||||
const movingEnemies = entityManager
|
||||
.query()
|
||||
.withAll(PositionComponent, VelocityComponent, HealthComponent)
|
||||
.withTag(2) // 敌人标签
|
||||
.execute();
|
||||
|
||||
// 查询活跃的玩家
|
||||
const activePlayers = entityManager
|
||||
.query()
|
||||
.withAll(PositionComponent)
|
||||
.withTag(1) // 玩家标签
|
||||
.active() // 只查询活跃实体
|
||||
.execute();
|
||||
|
||||
// 排除特定组件的实体
|
||||
const nonCombatEntities = entityManager
|
||||
.query()
|
||||
.withAll(PositionComponent)
|
||||
.without(WeaponComponent, HealthComponent)
|
||||
.execute();
|
||||
|
||||
// 自定义条件查询
|
||||
const nearbyEnemies = entityManager
|
||||
.query()
|
||||
.withAll(PositionComponent)
|
||||
.withTag(2)
|
||||
.where(entity => {
|
||||
const pos = entity.getComponent(PositionComponent);
|
||||
return pos && Math.abs(pos.x - playerX) < 100;
|
||||
})
|
||||
.execute();
|
||||
```
|
||||
|
||||
## 实体管理
|
||||
|
||||
### 创建和销毁实体
|
||||
|
||||
```typescript
|
||||
// 创建单个实体
|
||||
const player = entityManager.createEntity("Player");
|
||||
player.addComponent(new PositionComponent(400, 300));
|
||||
player.addComponent(new HealthComponent(100));
|
||||
player.tag = 1;
|
||||
|
||||
// 销毁实体
|
||||
entityManager.destroyEntity(player);
|
||||
|
||||
// 按名称销毁
|
||||
entityManager.destroyEntity("Enemy_1");
|
||||
|
||||
// 按ID销毁
|
||||
entityManager.destroyEntity(123);
|
||||
```
|
||||
|
||||
### 实体查找
|
||||
|
||||
```typescript
|
||||
// 按ID查找
|
||||
const entity = entityManager.getEntity(123);
|
||||
|
||||
// 按名称查找
|
||||
const player = entityManager.getEntityByName("Player");
|
||||
|
||||
// 检查实体是否存在
|
||||
if (entity && !entity.isDestroyed) {
|
||||
// 实体有效
|
||||
}
|
||||
```
|
||||
|
||||
## 性能监控
|
||||
|
||||
### 基础统计
|
||||
|
||||
```typescript
|
||||
// 获取实体数量
|
||||
console.log('总实体数:', entityManager.entityCount);
|
||||
console.log('活跃实体数:', entityManager.activeEntityCount);
|
||||
|
||||
// 获取场景统计
|
||||
const sceneStats = scene.getStats();
|
||||
console.log('场景统计:', {
|
||||
实体数量: sceneStats.entityCount,
|
||||
系统数量: sceneStats.processorCount
|
||||
});
|
||||
|
||||
// 获取查询系统统计
|
||||
const queryStats = scene.querySystem.getStats();
|
||||
console.log('查询统计:', queryStats);
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 高效查询
|
||||
|
||||
```typescript
|
||||
// ✅ 好的做法:缓存查询结果
|
||||
class CombatSystem extends EntitySystem {
|
||||
private cachedEnemies: Entity[] = [];
|
||||
private lastUpdateFrame = 0;
|
||||
|
||||
protected process(entities: Entity[]): void {
|
||||
// 每5帧更新一次缓存
|
||||
if (Time.frameCount - this.lastUpdateFrame > 5) {
|
||||
this.cachedEnemies = this.entityManager
|
||||
.query()
|
||||
.withAll(PositionComponent, HealthComponent)
|
||||
.withTag(2)
|
||||
.execute();
|
||||
this.lastUpdateFrame = Time.frameCount;
|
||||
}
|
||||
|
||||
// 使用缓存的结果
|
||||
this.cachedEnemies.forEach(enemy => {
|
||||
// 处理敌人逻辑
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 批量操作
|
||||
|
||||
```typescript
|
||||
// ✅ 好的做法:批量创建和配置
|
||||
function createBulletWave(count: number): Entity[] {
|
||||
// 使用Scene的批量创建
|
||||
const bullets = scene.createEntities(count, "Bullet");
|
||||
|
||||
// 批量配置组件
|
||||
bullets.forEach((bullet, index) => {
|
||||
const angle = (index / count) * Math.PI * 2;
|
||||
bullet.addComponent(new PositionComponent(400, 300));
|
||||
bullet.addComponent(new VelocityComponent(
|
||||
Math.cos(angle) * 200,
|
||||
Math.sin(angle) * 200
|
||||
));
|
||||
bullet.addComponent(new BulletComponent());
|
||||
bullet.tag = 3; // 子弹标签
|
||||
});
|
||||
|
||||
return bullets;
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 内存管理
|
||||
|
||||
```typescript
|
||||
// ✅ 好的做法:及时清理无用实体
|
||||
class CleanupSystem extends EntitySystem {
|
||||
protected process(entities: Entity[]): void {
|
||||
// 清理超出边界的子弹
|
||||
const bullets = this.entityManager.getEntitiesByTag(3);
|
||||
bullets.forEach(bullet => {
|
||||
const pos = bullet.getComponent(PositionComponent);
|
||||
if (pos && (pos.x < -100 || pos.x > 900 || pos.y < -100 || pos.y > 700)) {
|
||||
this.entityManager.destroyEntity(bullet);
|
||||
}
|
||||
});
|
||||
|
||||
// 清理死亡的敌人
|
||||
const deadEnemies = this.entityManager
|
||||
.query()
|
||||
.withAll(HealthComponent)
|
||||
.withTag(2)
|
||||
.where(entity => {
|
||||
const health = entity.getComponent(HealthComponent);
|
||||
return health && health.currentHealth <= 0;
|
||||
})
|
||||
.execute();
|
||||
|
||||
deadEnemies.forEach(enemy => {
|
||||
this.entityManager.destroyEntity(enemy);
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 查询优化
|
||||
|
||||
```typescript
|
||||
// ✅ 好的做法:使用合适的查询方法
|
||||
class GameSystem extends EntitySystem {
|
||||
findTargetsInRange(attacker: Entity, range: number): Entity[] {
|
||||
const attackerPos = attacker.getComponent(PositionComponent);
|
||||
if (!attackerPos) return [];
|
||||
|
||||
// 先按标签快速筛选,再按距离过滤
|
||||
return this.entityManager
|
||||
.getEntitiesByTag(2) // 敌人标签
|
||||
.filter(enemy => {
|
||||
const enemyPos = enemy.getComponent(PositionComponent);
|
||||
if (!enemyPos) return false;
|
||||
|
||||
const distance = Math.sqrt(
|
||||
Math.pow(attackerPos.x - enemyPos.x, 2) +
|
||||
Math.pow(attackerPos.y - enemyPos.y, 2)
|
||||
);
|
||||
return distance <= range;
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 完整示例
|
||||
|
||||
```typescript
|
||||
import {
|
||||
EntityManager,
|
||||
Scene,
|

|
||||
enemy.addComponent(new PositionComponent(
|

Math.random() * 600
|

}
|
||||
|
||||
public update(): void {
|
||||
this.scene.update();
|
||||
|
||||
// 输出统计信息
|
||||
console.log('实体数量:', this.entityManager.entityCount);
|
||||
console.log('活跃实体数:', this.entityManager.activeEntityCount);
|
||||
}
|
||||
}
|
||||
|
||||
// 生命值系统
|
||||
class HealthSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.empty().all(HealthComponent));
|
||||
}
|
||||
|
||||
protected process(entities: Entity[]): void {
|
||||
const healthEntities = this.scene.querySystem.queryAll(HealthComponent);
|
||||
|
||||
healthEntities.entities.forEach(entity => {
|
||||
const health = entity.getComponent(HealthComponent);
|
||||
if (health && health.currentHealth <= 0) {
|
||||
console.log(`实体 ${entity.name} 死亡`);
|
||||
entity.destroy();
|
||||
}
|
||||
});
|
||||
}
|
||||
}
|
||||
|
||||
// 启动游戏
|
||||
const game = new GameManager();
|
||||
setInterval(() => game.update(), 16); // 60 FPS
|
||||
```
|
||||
|
||||
## 总结
|
||||
|
||||
EntityManager 提供了强大的实体管理功能:
|
||||
|
||||
- **创建管理**:`createEntity()`, `destroyEntity()`
|
||||
- **查询功能**:`getEntitiesWithComponent()`, `getEntitiesByTag()`, `query()`
|
||||
- **实体查找**:`getEntity()`, `getEntityByName()`
|
||||
- **统计信息**:`entityCount`, `activeEntityCount`
|
||||
|
||||
通过合理使用这些API,可以构建高性能的游戏系统。记住要及时清理无用实体,缓存频繁查询的结果,并使用合适的查询方法来优化性能。

### 创建事件总线
|
||||
|
||||
```typescript
|
||||
import { EventBus, GlobalEventBus } from './ECS';
|
||||
|
||||
// 方式1:创建独立的事件总线
|

### 基本事件发布订阅
|
||||
|
||||
```typescript
|
||||
// 定义事件数据类型
|
||||
interface PlayerDiedEvent {
|
||||
playerId: number;
|
||||
cause: string;
|
||||
position: { x: number; y: number };
|
||||
}
|
||||
|
||||
// 监听事件
|
||||
const listenerId = eventBus.on<PlayerDiedEvent>('player:died', (data) => {
|
||||
console.log(`Player ${data.playerId} died at (${data.position.x}, ${data.position.y})`);
|
||||
console.log(`Cause: ${data.cause}`);
|
||||
});
|
||||
|
||||
// 发射事件
|
||||
eventBus.emit('player:died', {
|
||||
playerId: 123,
|
||||
cause: 'enemy_attack',
|
||||
position: { x: 100, y: 200 }
|
||||
});
|
||||
|
||||
// 移除监听器
|
||||
eventBus.off('player:died', listenerId);
|
||||
```
|
||||
|
||||
### 一次性事件监听
|
||||
|
||||
```typescript
|
||||
// 只监听一次
|
||||
eventBus.once<PlayerDiedEvent>('player:died', (data) => {
|
||||
console.log('This will only be called once');
|
||||
});
|
||||
```
|
||||
|
||||
### 异步事件处理
|
||||
|
||||
```typescript
|
||||
// 异步事件监听
|
||||
eventBus.onAsync<PlayerDiedEvent>('player:died', async (data) => {
|
||||
await savePlayerDeathToDatabase(data);
|
||||
await updateLeaderboard(data.playerId);
|
||||
});
|
||||
|
||||
// 异步事件发射
|
||||
await eventBus.emitAsync('player:died', playerData);
|
||||
```
|
||||
|
||||
## 预定义ECS事件
|
||||
|
||||
框架提供了完整的ECS事件类型定义,支持实体、组件、系统等核心概念的事件。
|
||||
|
||||
### 实体事件
|
||||
|
||||
```typescript
|
||||
import { ECSEventType, IEntityEventData } from './ECS';
|
||||
|
||||
// 监听实体创建事件
|
||||
eventBus.onEntityCreated((data: IEntityEventData) => {
|
||||
console.log(`Entity created: ${data.entityName} (ID: ${data.entityId})`);
|
||||
});
|
||||
|
||||
// 监听实体销毁事件
|
||||
eventBus.on<IEntityEventData>(ECSEventType.ENTITY_DESTROYED, (data) => {
|
||||
console.log(`Entity destroyed: ${data.entityName}`);
|
||||
});
|
||||
|
||||
// 手动发射实体事件
|
||||
eventBus.emitEntityCreated({
|
||||
timestamp: Date.now(),
|
||||
source: 'GameManager',
|
||||
entityId: 123,
|
||||
entityName: 'Player',
|
||||
entityTag: 'player'
|
||||
});
|
||||
```
|
||||
|
||||
### 组件事件
|
||||
|
||||
```typescript
|
||||
import { IComponentEventData } from './ECS';
|
||||
|
||||
// 监听组件添加事件
|
||||
eventBus.onComponentAdded((data: IComponentEventData) => {
|
||||
console.log(`Component ${data.componentType} added to entity ${data.entityId}`);
|
||||
});
|
||||
|
||||
// 监听组件移除事件
|
||||
eventBus.on<IComponentEventData>(ECSEventType.COMPONENT_REMOVED, (data) => {
|
||||
console.log(`Component ${data.componentType} removed from entity ${data.entityId}`);
|
||||
});
|
||||
```
|
||||
|
||||
### 系统事件
|
||||
|
||||
```typescript
|
||||
import { ISystemEventData } from './ECS';
|
||||
|
||||
// 监听系统错误
|
||||
eventBus.onSystemError((data: ISystemEventData) => {
|
||||
console.error(`System error in ${data.systemName}: ${data.systemType}`);
|
||||
});
|
||||
|
||||
// 监听系统处理开始/结束
|
||||
eventBus.on<ISystemEventData>(ECSEventType.SYSTEM_PROCESSING_START, (data) => {
|
||||
console.log(`System ${data.systemName} started processing`);
|
||||
});
|
||||
```
|
||||
|
||||
### 性能事件
|
||||
|
||||
```typescript
|
||||
import { IPerformanceEventData } from './ECS';
|
||||
|
||||
// 监听性能警告
|
||||
eventBus.onPerformanceWarning((data: IPerformanceEventData) => {
|
||||
console.warn(`Performance warning: ${data.operation} took ${data.executionTime}ms`);
|
||||
});
|
||||
|
||||
// 监听内存使用过高
|
||||
eventBus.on<IPerformanceEventData>(ECSEventType.MEMORY_USAGE_HIGH, (data) => {
|
||||
console.warn(`High memory usage: ${data.memoryUsage}MB`);
|
||||
});
|
||||
```
|
||||
|
||||
## 事件装饰器
|
||||
|
||||
使用装饰器可以自动注册事件监听器,简化代码编写。
|
||||
|
||||
### 基础装饰器
|
||||
|
||||
```typescript
|
||||
import { EventHandler, AsyncEventHandler, EventPriority } from './ECS';
|
||||
|
||||
class GameManager {
|
||||
@EventHandler(ECSEventType.ENTITY_CREATED, { priority: EventPriority.HIGH })
|
||||
onEntityCreated(data: IEntityEventData) {
|
||||
console.log(`New entity: ${data.entityName}`);
|
||||
}
|
||||
|
||||
@AsyncEventHandler(ECSEventType.ENTITY_DESTROYED)
|
||||
async onEntityDestroyed(data: IEntityEventData) {
|
||||
await this.cleanupEntityResources(data.entityId);
|
||||
}
|
||||
|
||||
@EventHandler('custom:game:event', { once: true })
|
||||
onGameStart(data: any) {
|
||||
console.log('Game started!');
|
||||
}
|
||||
|
||||
// 需要手动调用初始化方法
|
||||
constructor() {
|
||||
// 如果类有initEventListeners方法,会自动注册装饰器定义的监听器
|
||||
if (this.initEventListeners) {
|
||||
this.initEventListeners();
|
||||
}
|
||||
}
|
||||
|
||||
private async cleanupEntityResources(entityId: number) {
|
||||
// 清理实体相关资源
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 优先级和配置
|
||||
|
||||
```typescript
|
||||
class SystemManager {
|
||||
@EventHandler(ECSEventType.SYSTEM_ERROR, {
|
||||
priority: EventPriority.CRITICAL,
|
||||
context: this
|
||||
})
|
||||
handleSystemError(data: ISystemEventData) {
|
||||
this.logError(data);
|
||||
this.restartSystem(data.systemName);
|
||||
}
|
||||
|
||||
@AsyncEventHandler(ECSEventType.PERFORMANCE_WARNING, {
|
||||
priority: EventPriority.LOW,
|
||||
async: true
|
||||
})
|
||||
async handlePerformanceWarning(data: IPerformanceEventData) {
|
||||
await this.optimizePerformance(data);
|
||||
}
|
||||
|
||||
private logError(data: ISystemEventData) {
|
||||
// 错误日志记录
|
||||
}
|
||||
|
||||
private restartSystem(systemName: string) {
|
||||
// 重启系统
|
||||
}
|
||||
|
||||
private async optimizePerformance(data: IPerformanceEventData) {
|
||||
// 性能优化逻辑
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 高级功能
|
||||
|
||||
### 事件批处理
|
||||
|
||||
```typescript
|
||||
// 设置批处理配置
|
||||
eventBus.setBatchConfig('entity:update', 100, 16); // 批量100个,延迟16ms
|
||||
|
||||
// 发射事件(会被批处理)
|
||||
for (let i = 0; i < 1000; i++) {
|
||||
eventBus.emit('entity:update', { entityId: i, data: 'update' });
|
||||
}
|
||||
|
||||
// 手动刷新批处理队列
|
||||
eventBus.flushBatch('entity:update');
|
||||
```
|
||||
|
||||
### 事件统计和监控
|
||||
|
||||
```typescript
|
||||
// 获取单个事件统计
|
||||
const stats = eventBus.getStats('entity:created');
|
||||
console.log(`Event triggered ${stats.triggerCount} times`);
|
||||
console.log(`Average execution time: ${stats.averageExecutionTime}ms`);
|
||||
|
||||
// 获取所有事件统计
|
||||
const allStats = eventBus.getStats();
|
||||
if (allStats instanceof Map) {
|
||||
allStats.forEach((stat, eventType) => {
|
||||
console.log(`${eventType}: ${stat.triggerCount} triggers`);
|
||||
});
|
||||
}
|
||||
|
||||
// 重置统计
|
||||
eventBus.resetStats('entity:created');
|
||||
```
|
||||
|
||||
### 事件类型验证
|
||||
|
||||
```typescript
|
||||
import { EventTypeValidator } from './ECS';
|
||||
|
||||
// 检查事件类型是否有效
|
||||
if (EventTypeValidator.isValid('entity:created')) {
|
||||
eventBus.emit('entity:created', data);
|
||||
}
|
||||
|
||||
// 添加自定义事件类型
|
||||
EventTypeValidator.addCustomType('game:custom:event');
|
||||
|
||||
// 获取所有有效事件类型
|
||||
const validTypes = EventTypeValidator.getAllValidTypes();
|
||||
console.log('Valid event types:', validTypes);
|
||||
```
|
||||
|
||||
### 调试和日志
|
||||
|
||||
```typescript
|
||||
// 启用调试模式
|
||||
eventBus.setDebugMode(true);
|
||||
|
||||
// 设置最大监听器数量
|
||||
eventBus.setMaxListeners(50);
|
||||
|
||||
// 检查是否有监听器
|
||||
if (eventBus.hasListeners('entity:created')) {
|
||||
console.log('Has listeners for entity:created');
|
||||
}
|
||||
|
||||
// 获取监听器数量
|
||||
const count = eventBus.getListenerCount('entity:created');
|
||||
console.log(`${count} listeners for entity:created`);
|
||||
```
|
||||
|
||||
## 性能优化
|
||||
|
||||
### 事件过滤和条件监听
|
||||
|
||||
```typescript
|
||||
// 使用条件过滤减少不必要的事件处理
|
||||
eventBus.on<IEntityEventData>(ECSEventType.ENTITY_CREATED, (data) => {
|
||||
// 只处理玩家实体
|
||||
if (data.entityTag === 'player') {
|
||||
handlePlayerCreated(data);
|
||||
}
|
||||
});
|
||||
|
||||
// 更好的方式:使用具体的事件类型
|
||||
eventBus.on<IEntityEventData>('entity:player:created', handlePlayerCreated);
|
||||
```
|
||||
|
||||
### 内存管理
|
||||
|
||||
```typescript
|
||||
class EventManager {
|
||||
private listeners: string[] = [];
|
||||
|
||||
public setupListeners() {
|
||||
// 保存监听器ID以便清理
|
||||
this.listeners.push(
|
||||
eventBus.on('event1', this.handler1.bind(this)),
|
||||
eventBus.on('event2', this.handler2.bind(this))
|
||||
);
|
||||
}
|
||||
|
||||
public cleanup() {
|
||||
// 清理所有监听器
|
||||
this.listeners.forEach(id => {
|
||||
eventBus.off('event1', id);
|
||||
eventBus.off('event2', id);
|
||||
});
|
||||
this.listeners.length = 0;
|
||||
}
|
||||
|
||||
private handler1(data: any) { /* ... */ }
|
||||
private handler2(data: any) { /* ... */ }
|
||||
}
|
||||
```
|
||||
|
||||
### 异步事件优化
|
||||
|
||||
```typescript
|
||||
// 使用Promise.all并行处理多个异步事件
|
||||
const promises = [
|
||||
eventBus.emitAsync('save:player', playerData),
|
||||
eventBus.emitAsync('update:leaderboard', scoreData),
|
||||
eventBus.emitAsync('notify:friends', notificationData)
|
||||
];
|
||||
|
||||
await Promise.all(promises);
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 事件命名规范
|
||||
|
||||
```typescript
|
||||
// 推荐的事件命名格式:模块:对象:动作
|
||||
const EVENT_NAMES = {
|
||||
// 实体相关
|
||||
ENTITY_PLAYER_CREATED: 'entity:player:created',
|
||||
ENTITY_ENEMY_DESTROYED: 'entity:enemy:destroyed',
|
||||
|
||||
// 游戏逻辑相关
|
||||
GAME_LEVEL_COMPLETED: 'game:level:completed',
|
||||
GAME_SCORE_UPDATED: 'game:score:updated',
|
||||
|
||||
// UI相关
|
||||
UI_MENU_OPENED: 'ui:menu:opened',
|
||||
UI_BUTTON_CLICKED: 'ui:button:clicked'
|
||||
};
|
||||
```
|
||||
|
||||
### 2. 类型安全
|
||||
|
||||
```typescript
|
||||
// 定义强类型的事件数据接口
|
||||
interface GameEvents {
|
||||
'player:levelup': { playerId: number; newLevel: number; experience: number };
|
||||
'inventory:item:added': { itemId: string; quantity: number; playerId: number };
|
||||
'combat:damage:dealt': { attackerId: number; targetId: number; damage: number };
|
||||
}
|
||||
|
||||
// 创建类型安全的事件发射器
|
||||
class TypedEventBus {
|
||||
private eventBus = new EventBus();
|
||||
|
||||
emit<K extends keyof GameEvents>(eventType: K, data: GameEvents[K]) {
|
||||
this.eventBus.emit(eventType, data);
|
||||
}
|
||||
|
||||
on<K extends keyof GameEvents>(
|
||||
eventType: K,
|
||||
handler: (data: GameEvents[K]) => void
|
||||
) {
|
||||
return this.eventBus.on(eventType, handler);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 错误处理
|
||||
|
||||
```typescript
|
||||
// 在事件处理器中添加错误处理
|
||||
eventBus.on<IEntityEventData>(ECSEventType.ENTITY_CREATED, (data) => {
|
||||
try {
|
||||
processEntityCreation(data);
|
||||
} catch (error) {
|
||||
console.error('Error processing entity creation:', error);
|
||||
// 发射错误事件
|
||||
eventBus.emit(ECSEventType.ERROR_OCCURRED, {
|
||||
timestamp: Date.now(),
|
||||
source: 'EntityCreationHandler',
|
||||
error: error.message,
|
||||
context: data
|
||||
});
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### 4. 模块化事件管理
|
||||
|
||||
```typescript
|
||||
// 为不同模块创建专门的事件管理器
|
||||
class PlayerEventManager {
|
||||
constructor(private eventBus: EventBus) {
|
||||
this.setupListeners();
|
||||
}
|
||||
|
||||
private setupListeners() {
|
||||
this.eventBus.onEntityCreated(this.onPlayerCreated.bind(this));
|
||||
this.eventBus.on('player:levelup', this.onPlayerLevelUp.bind(this));
|
||||
this.eventBus.on('player:died', this.onPlayerDied.bind(this));
|
||||
}
|
||||
|
||||
private onPlayerCreated(data: IEntityEventData) {
|
||||
if (data.entityTag === 'player') {
|
||||
// 处理玩家创建逻辑
|
||||
}
|
||||
}
|
||||
|
||||
private onPlayerLevelUp(data: any) {
|
||||
// 处理玩家升级逻辑
|
||||
}
|
||||
|
||||
private onPlayerDied(data: any) {
|
||||
// 处理玩家死亡逻辑
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 5. 与EntityManager集成
|
||||
|
||||
```typescript
|
||||
import { EntityManager } from './ECS';
|
||||
|
||||
// EntityManager会自动设置事件总线
|
||||
const entityManager = new EntityManager();
|
||||
|
||||
// 获取事件总线实例
|
||||
const eventBus = entityManager.eventBus;
|
||||
|
||||
// 监听自动发射的ECS事件
|
||||
eventBus.onEntityCreated((data) => {
|
||||
console.log('Entity created automatically:', data);
|
||||
});
|
||||
|
||||
eventBus.onComponentAdded((data) => {
|
||||
console.log('Component added automatically:', data);
|
||||
});
|
||||
|
||||
// 创建实体时会自动发射事件
|
||||
const entity = entityManager.createEntity('Player');
|
||||
|
||||
// 添加组件时会自动发射事件
|
||||
entity.addComponent(new HealthComponent(100));
|
||||
```
|
||||
|
||||
## 总结
|
||||
|
||||

|
||||
|
||||
- **类型安全**:完整的TypeScript类型支持

# 快速入门
|
||||
|
||||
本指南将帮助您快速上手 ECS Framework,这是一个专业级的实体组件系统框架,采用现代化架构设计,专为高性能游戏开发打造。
|
||||
|
||||
## 安装
|
||||
|
||||
```bash
|
||||
npm install @esengine/ecs-framework
|
||||
```
|
||||
|
||||
## 更新机制说明
|
||||
|
||||
ECS框架需要在游戏引擎的更新循环中调用,并传入deltaTime:
|
||||
|
||||
```typescript
|
||||
// 统一的更新方式:让外部引擎传入deltaTime
|
||||
Core.update(deltaTime);
|
||||
```
|
||||
|
||||
**不同平台的集成方式:**
|
||||
- **Laya引擎**:使用 `Laya.timer.delta / 1000`
|
||||
- **Cocos Creator**:使用组件的 `update(deltaTime)` 参数
|
||||
- **原生浏览器**:自己计算deltaTime
|
||||
- **Node.js服务器**:自己计算deltaTime
|
||||
|
||||
**优势:**
|
||||
- 与引擎时间系统完全同步
|
||||
- 支持引擎的时间缩放和暂停功能
|
||||
- 更精确的时间控制
|
||||
- 统一的API,简化集成
|
||||
|
||||
## Core配置
|
||||
|
||||
### 基础配置
|
||||
|
||||
ECS框架提供了灵活的配置选项来满足不同项目需求:
|
||||
|
||||
```typescript
|
||||
import { Core, ICoreConfig } from '@esengine/ecs-framework';
|
||||
|
||||
// 方式1:简化配置(向后兼容)
|
||||
Core.create(true); // 启用调试模式
|
||||
Core.create(false); // 发布模式
|
||||
Core.create(); // 默认调试模式
|
||||
|
||||
// 方式2:详细配置(推荐)
|
||||
const config: ICoreConfig = {
|
||||
debug: true, // 启用调试模式
|
||||
enableEntitySystems: true, // 启用实体系统(默认true)
|
||||
debugConfig: { // 可选:远程调试配置

#### 通用调试配置
|
||||
|
||||
```typescript
|
||||
// 运行时启用调试
|
||||
Core.enableDebug({
|
||||
enabled: true,
|
||||
websocketUrl: 'ws://localhost:8080',
|
||||
autoReconnect: true,
|
||||
updateInterval: 500,
|
||||
channels: {
|
||||
entities: true,
|
||||
systems: true,
|
||||
performance: true,
|
||||
components: false, // 可以选择性禁用某些通道
|
||||
scenes: true
|
||||
}
|
||||
});
|
||||
|
||||
// 获取调试数据
|
||||
const debugData = Core.getDebugData();
|
||||
console.log('当前实体数量:', debugData?.entities?.totalEntities);
|
||||
|
||||
// 禁用调试
|
||||
Core.disableDebug();
|
||||
|
||||
// 检查调试状态
|
||||
if (Core.isDebugEnabled) {
|
||||
console.log('调试模式已启用');
|
||||
}
|
||||
```
|
||||
|
||||
### 生产环境配置建议
|
||||

||||
performance: true,
|
||||
components: true,
|
||||
scenes: true
|
||||
}
|
||||
}
|
||||
};
|
||||
|
||||
// 生产环境
|
||||
const prodConfig: ICoreConfig = {
|
||||
debug: false, // 关闭调试以提升性能
|
||||
enableEntitySystems: true,
|
||||
// debugConfig 可以省略或设为 undefined
|
||||
};
|
||||
|
||||
const isDevelopment = process.env.NODE_ENV === 'development';
|
||||
Core.create(isDevelopment ? devConfig : prodConfig);
|
||||
```
|
||||
|
||||
**💡 调试功能说明:**
|
||||
- **Cocos Creator**:推荐使用[官方调试插件](https://store.cocos.com/app/detail/7823)获得最佳调试体验

```
|
||||
|
||||
## 基础组件定义
|
||||
|
||||
```typescript
|
||||
import { Component } from '@esengine/ecs-framework';
|
||||
|
||||
// 位置组件
|
||||
class PositionComponent extends Component {
|
||||
public x: number = 0;
|
||||
public y: number = 0;
|
||||
|
||||
constructor(x: number = 0, y: number = 0) {
|
||||
super();
|
||||
this.x = x;
|
||||
this.y = y;
|
||||
}
|
||||
|
||||
public reset() {
|
||||
this.x = 0;
|
||||
this.y = 0;
|
||||
}
|
||||
}
|
||||
|
||||
// 速度组件
|
||||
class VelocityComponent extends Component {
|
||||
public x: number = 0;
|
||||
public y: number = 0;
|
||||
|
||||
constructor(x: number = 0, y: number = 0) {
|
||||
super();
|
||||

|
||||
this.y = y;
|
||||
}
|
||||
|
||||
public reset() {
|
||||
this.x = 0;
|
||||
this.y = 0;
|
||||
}
|
||||
}
|
||||
|
||||
// 生命值组件
|
||||
class HealthComponent extends Component {
|
||||
public maxHealth: number = 100;
|
||||
public currentHealth: number = 100;
|
||||
|
||||
constructor(maxHealth: number = 100) {
|
||||
super();
|
||||
this.maxHealth = maxHealth;
|
||||
this.currentHealth = maxHealth;
|
||||
}
|
||||
|
||||
public reset() {
|
||||
this.maxHealth = 100;
|
||||
this.currentHealth = 100;
|
||||
}
|
||||
|
||||
public takeDamage(damage: number): void {
|
||||
this.currentHealth = Math.max(0, this.currentHealth - damage);
|
||||
}
|
||||
|
||||
public heal(amount: number): void {
|
||||
this.currentHealth = Math.min(this.maxHealth, this.currentHealth + amount);
|
||||
}
|
||||
|
||||
public isDead(): boolean {
|
||||
return this.currentHealth <= 0;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 基础系统创建
|
||||
|
||||
```typescript
|
||||
import { EntitySystem, Entity, Matcher, Time } from '@esengine/ecs-framework';
|
||||
|
||||
class MovementSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.empty().all(PositionComponent, VelocityComponent));
|
||||
}
|
||||
|
||||
protected process(entities: Entity[]): void {
|
||||
const movingEntities = this.scene.querySystem.queryAll(PositionComponent, VelocityComponent);
|
||||
|
||||
movingEntities.entities.forEach(entity => {
|
||||
const position = entity.getComponent(PositionComponent);
|
||||
const velocity = entity.getComponent(VelocityComponent);
|
||||
|
||||
if (position && velocity) {
|
||||
position.x += velocity.x * Time.deltaTime;
|
||||
position.y += velocity.y * Time.deltaTime;
|
||||
}
|
||||
});
|
||||
}
|
||||
}
|
||||
|
||||
class HealthSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.empty().all(HealthComponent));
|
||||
}
|
||||
|
||||
protected process(entities: Entity[]): void {
|
||||
const healthEntities = this.scene.querySystem.queryAll(HealthComponent);
|
||||
|
||||
healthEntities.entities.forEach(entity => {
|
||||
const health = entity.getComponent(HealthComponent);
|
||||
if (health && health.currentHealth <= 0) {
|
||||
entity.destroy();
|
||||
}
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 实体管理
|
||||
|
||||
```typescript
|
||||
// 创建实体
|
||||
const player = entityManager.createEntity("Player");
|
||||
player.addComponent(new PositionComponent(100, 100));
|
||||
player.addComponent(new VelocityComponent(5, 0));
|
||||
player.addComponent(new HealthComponent(100));
|
||||
|
||||
// 批量创建实体
|
||||
const enemies = scene.createEntities(50, "Enemy");
|
||||
enemies.forEach(enemy => {
|
||||
enemy.addComponent(new PositionComponent(Math.random() * 800, Math.random() * 600));
|
||||
enemy.addComponent(new HealthComponent(50));
|
||||
});
|
||||
|
||||
// 查询实体
|
||||
const movingEntities = entityManager
|
||||
.query()
|
||||
.withAll(PositionComponent, VelocityComponent)
|
||||
.execute();
|
||||
|
||||
const healthEntities = entityManager.getEntitiesWithComponent(HealthComponent);
|
||||
const enemiesByTag = entityManager.getEntitiesByTag(2);
|
||||
```
|
||||
|
||||
## 事件系统
|
||||
|
||||
推荐使用Scene的事件系统或EntityManager的事件系统:
|
||||
|
||||
```typescript
|
||||
// 使用EntityManager的事件系统(推荐)
|
||||
const eventBus = entityManager.eventBus;
|
||||
|
||||
// 监听ECS事件
|
||||
eventBus.onEntityCreated((data) => {
|
||||
console.log(`实体创建: ${data.entityName}`);
|
||||
});
|
||||
|
||||
eventBus.onComponentAdded((data) => {
|
||||
console.log(`组件添加: ${data.componentType}`);
|
||||
});
|
||||
|
||||
// 发射自定义事件
|
||||
eventBus.emit('player:died', { player: entity, score: 1000 });
|
||||
|
||||
// 使用装饰器自动注册事件监听器
|
||||
import { EventHandler } from '@esengine/ecs-framework';
|
||||
|
||||
class GameSystem {
|
||||
@EventHandler('player:died')
|
||||
onPlayerDied(data: { player: Entity; score: number }) {
|
||||
console.log(`玩家死亡,得分: ${data.score}`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 性能监控
|
||||
|
||||
```typescript
|
||||
// 获取场景统计
|
||||
const sceneStats = scene.getStats();
|
||||
console.log('实体数量:', sceneStats.entityCount);
|
||||
console.log('系统数量:', sceneStats.processorCount);
|
||||
|
||||
// 获取查询统计
|
||||
const queryStats = scene.querySystem.getStats();
|
||||
console.log('查询统计:', queryStats);
|
||||
```

# 高级用法
|
||||
|
||||
本文介绍行为树系统的高级功能和使用技巧。
|
||||
|
||||
## 全局黑板
|
||||
|
||||
全局黑板在所有行为树实例之间共享数据。
|
||||
|
||||
### 使用全局黑板
|
||||
|
||||
```typescript
|
||||
import { GlobalBlackboardService } from '@esengine/behavior-tree';
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
|
||||
// 获取全局黑板服务
|
||||
const globalBlackboard = Core.services.resolve(GlobalBlackboardService);
|
||||
|
||||
// 设置全局变量
|
||||
globalBlackboard.setValue('gameState', 'playing');
|
||||
globalBlackboard.setValue('playerCount', 4);
|
||||
globalBlackboard.setValue('difficulty', 'hard');
|
||||
|
||||
// 读取全局变量
|
||||
const gameState = globalBlackboard.getValue('gameState');
|
||||
const playerCount = globalBlackboard.getValue<number>('playerCount');
|
||||
```
|
||||
|
||||
### 在自定义执行器中访问全局黑板
|
||||
|
||||
```typescript
|
||||
import { INodeExecutor, NodeExecutionContext, BindingHelper } from '@esengine/behavior-tree';
|
||||
import { GlobalBlackboardService } from '@esengine/behavior-tree';
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
|
||||
export class CheckGameState implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const globalBlackboard = Core.services.resolve(GlobalBlackboardService);
|
||||
const gameState = globalBlackboard.getValue('gameState');
|
||||
|
||||
if (gameState === 'paused') {
|
||||
return TaskStatus.Failure;
|
||||
}
|
||||
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 性能优化
|
||||
|
||||
### 1. 降低更新频率
|
||||
|
||||
对于不需要每帧更新的AI,可以使用冷却装饰器:
|
||||
|
||||
```typescript
|
||||
// 每0.1秒执行一次
|
||||
const ai = BehaviorTreeBuilder.create('ThrottledAI')
|
||||
.cooldown(0.1, 'ThrottleRoot')
|
||||
.selector('MainLogic')
|
||||
// AI逻辑...
|
||||
.end()
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 2. 条件缓存
|
||||
|
||||
在自定义执行器中缓存昂贵的条件检查结果:
|
||||
|
||||
```typescript
|
||||
export class CachedCheck implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const { state, runtime, totalTime } = context;
|
||||
const cacheTime = state.lastCheckTime || 0;
|
||||
|
||||
// 如果缓存未过期(1秒内),直接使用缓存结果
|
||||
if (totalTime - cacheTime < 1.0) {
|
||||
return state.cachedResult || TaskStatus.Failure;
|
||||
}
|
||||
|
||||
// 执行昂贵的检查
|
||||
const result = performExpensiveCheck();
|
||||
const status = result ? TaskStatus.Success : TaskStatus.Failure;
|
||||
|
||||
// 缓存结果
|
||||
state.cachedResult = status;
|
||||
state.lastCheckTime = totalTime;
|
||||
|
||||
return status;
|
||||
}
|
||||
|
||||
reset(context: NodeExecutionContext): void {
|
||||
context.state.cachedResult = undefined;
|
||||
context.state.lastCheckTime = undefined;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 分帧执行
|
||||
|
||||
将大量计算分散到多帧:
|
||||
|
||||
```typescript
|
||||
export class ProcessLargeDataset implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const { state, runtime } = context;
|
||||
|
||||
const data = runtime.getBlackboardValue<any[]>('dataset') || [];
|
||||
let processedIndex = state.processedIndex || 0;
|
||||
|
||||
const batchSize = 100; // 每帧处理100个
|
||||
const endIndex = Math.min(processedIndex + batchSize, data.length);
|
||||
|
||||
for (let i = processedIndex; i < endIndex; i++) {
|
||||
processItem(data[i]);
|
||||
}
|
||||
|
||||
state.processedIndex = endIndex;
|
||||
|
||||
if (endIndex >= data.length) {
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
|
||||
return TaskStatus.Running;
|
||||
}
|
||||
|
||||
reset(context: NodeExecutionContext): void {
|
||||
context.state.processedIndex = 0;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 调试技巧
|
||||
|
||||
### 1. 使用日志节点
|
||||
|
||||
在关键位置添加日志:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('Debug')
|
||||
.log('开始战斗序列', 'StartCombat')
|
||||
.sequence('Combat')
|
||||
.log('检查生命值', 'CheckHealth')
|
||||
.blackboardCompare('health', 0, 'greater')
|
||||
.log('执行攻击', 'Attack')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 2. 监控黑板状态
|
||||
|
||||
```typescript
|
||||
const runtime = entity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
|
||||
// 输出所有黑板变量
|
||||
console.log('黑板变量:', runtime?.getAllBlackboardVariables());
|
||||
|
||||
// 输出活动节点
|
||||
console.log('活动节点:', Array.from(runtime?.activeNodeIds || []));
|
||||
```
|
||||
|
||||
### 3. 在自定义执行器中调试
|
||||
|
||||
```typescript
|
||||
export class DebugAction implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const { nodeData, runtime, state } = context;
|
||||
|
||||
console.log(`[${nodeData.name}] 开始执行`);
|
||||
console.log('配置:', nodeData.config);
|
||||
console.log('状态:', state);
|
||||
console.log('黑板:', runtime.getAllBlackboardVariables());
|
||||
|
||||
// 执行逻辑...
|
||||
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 性能分析
|
||||
|
||||
测量节点执行时间:
|
||||
|
||||
```typescript
|
||||
export class ProfiledAction implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const startTime = performance.now();
|
||||
|
||||
// 执行操作
|
||||
doSomething();
|
||||
|
||||
const elapsed = performance.now() - startTime;
|
||||
console.log(`[${context.nodeData.name}] 耗时: ${elapsed.toFixed(2)}ms`);
|
||||
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 常见模式
|
||||
|
||||
### 1. 状态机模式
|
||||
|
||||
使用行为树实现状态机:
|
||||
|
||||
```typescript
|
||||
const fsm = BehaviorTreeBuilder.create('StateMachine')
|
||||
.defineBlackboardVariable('currentState', 'idle')
|
||||
.selector('StateSwitch')
|
||||
// Idle状态
|
||||
.sequence('IdleState')
|
||||
.blackboardCompare('currentState', 'idle', 'equals')
|
||||
.log('执行Idle行为', 'IdleBehavior')
|
||||
.end()
|
||||
// Move状态
|
||||
.sequence('MoveState')
|
||||
.blackboardCompare('currentState', 'move', 'equals')
|
||||
.log('执行Move行为', 'MoveBehavior')
|
||||
.end()
|
||||
// Attack状态
|
||||
.sequence('AttackState')
|
||||
.blackboardCompare('currentState', 'attack', 'equals')
|
||||
.log('执行Attack行为', 'AttackBehavior')
|
||||
.end()
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
状态转换通过修改黑板变量实现:
|
||||
|
||||
```typescript
|
||||
const runtime = entity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
runtime?.setBlackboardValue('currentState', 'move');
|
||||
```
|
||||
|
||||
### 2. 优先级队列模式
|
||||
|
||||
按优先级执行任务:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('PriorityQueue')
|
||||
.selector('Priorities')
|
||||
// 最高优先级:生存
|
||||
.sequence('Survive')
|
||||
.blackboardCompare('health', 20, 'less')
|
||||
.log('治疗', 'Heal')
|
||||
.end()
|
||||
// 中优先级:战斗
|
||||
.sequence('Combat')
|
||||
.blackboardExists('nearbyEnemy')
|
||||
.log('战斗', 'Fight')
|
||||
.end()
|
||||
// 低优先级:收集资源
|
||||
.sequence('Gather')
|
||||
.log('收集资源', 'CollectResources')
|
||||
.end()
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 3. 并行任务模式
|
||||
|
||||
同时执行多个任务:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('ParallelTasks')
|
||||
.parallel('Effects', { successPolicy: 'all' })
|
||||
.log('播放动画', 'PlayAnimation')
|
||||
.log('播放音效', 'PlaySound')
|
||||
.log('生成粒子', 'SpawnParticles')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 4. 重试模式
|
||||
|
||||
失败时重试:
|
||||
|
||||
```typescript
|
||||
// 使用自定义重试装饰器(参见custom-actions.md中的RetryDecorator示例)
|
||||
// 或者使用UntilSuccess装饰器
|
||||
const tree = BehaviorTreeBuilder.create('Retry')
|
||||
.untilSuccess('RetryUntilSuccess')
|
||||
.log('尝试操作', 'TryOperation')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 5. 超时模式
|
||||
|
||||
限制任务执行时间:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('Timeout')
|
||||
.timeout(5.0, 'TimeLimit')
|
||||
.log('长时间运行的任务', 'LongTask')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
## 与游戏引擎集成
|
||||
|
||||
### Cocos Creator集成
|
||||
|
||||
参见[Cocos Creator集成指南](./cocos-integration.md)
|
||||
|
||||
### LayaAir集成
|
||||
|
||||
参见[LayaAir集成指南](./laya-integration.md)
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 合理使用黑板
|
||||
|
||||
```typescript
|
||||
// 好的做法:使用类型化的黑板访问
|
||||
const health = runtime.getBlackboardValue<number>('health');
|
||||
|
||||
// 好的做法:定义所有黑板变量
|
||||
const tree = BehaviorTreeBuilder.create('AI')
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.defineBlackboardVariable('target', null)
|
||||
.defineBlackboardVariable('state', 'idle')
|
||||
// ...
|
||||
```
|
||||
|
||||
### 2. 避免过深的树结构
|
||||
|
||||
```typescript
|
||||
// 不好:嵌套过深
|
||||
.selector()
|
||||
.sequence()
|
||||
.selector()
|
||||
.sequence()
|
||||
.selector()
|
||||
// 太深了!
|
||||
.end()
|
||||
.end()
|
||||
.end()
|
||||
.end()
|
||||
.end()
|
||||
|
||||
// 好:使用合理的深度
|
||||
.selector()
|
||||
.sequence()
|
||||
.log('Action1')
|
||||
.log('Action2')
|
||||
.end()
|
||||
.sequence()
|
||||
.log('Action3')
|
||||
.log('Action4')
|
||||
.end()
|
||||
.end()
|
||||
```
|
||||
|
||||
### 3. 使用有意义的节点名称
|
||||
|
||||
```typescript
|
||||
// 好的做法
|
||||
.selector('CombatDecision')
|
||||
.sequence('AttackEnemy')
|
||||
.blackboardExists('target', 'HasTarget')
|
||||
.log('执行攻击', 'Attack')
|
||||
.end()
|
||||
.end()
|
||||
|
||||
// 不好的做法
|
||||
.selector('Node1')
|
||||
.sequence('Node2')
|
||||
.blackboardExists('target', 'Node3')
|
||||
.log('Attack', 'Node4')
|
||||
.end()
|
||||
.end()
|
||||
```
|
||||
|
||||
### 4. 模块化设计
|
||||
|
||||
将复杂逻辑分解为多个独立的行为树,在需要时组合使用。
|
||||
|
||||
### 5. 性能考虑
|
||||
|
||||
- 避免在每帧执行昂贵的操作
|
||||
- 使用冷却装饰器控制执行频率
|
||||
- 缓存计算结果
|
||||
- 合理使用并行节点
|
||||

# 资产管理
|
||||
|
||||
本文介绍如何加载、管理和复用行为树资产。
|
||||
|
||||
## 为什么需要资产管理?
|
||||
|
||||
在实际游戏开发中,你可能会遇到以下场景:
|
||||
|
||||
1. **多个实体共享同一个行为树** - 100个敌人使用同一套AI逻辑
|
||||
2. **动态加载行为树** - 从JSON文件加载行为树配置
|
||||
3. **子树复用** - 将常用的行为片段(如"巡逻"、"追击")做成独立的子树
|
||||
4. **运行时切换行为树** - 敌人在不同阶段使用不同的行为树
|
||||
|
||||
## BehaviorTreeAssetManager
|
||||
|
||||
框架提供了 `BehaviorTreeAssetManager` 服务来统一管理行为树资产。
|
||||
|
||||
### 核心概念
|
||||
|
||||
- **BehaviorTreeData(行为树数据)**:行为树的定义,可以被多个实体共享
|
||||
- **BehaviorTreeRuntimeComponent(运行时组件)**:每个实体独立的运行时状态
|
||||
- **AssetManager(资产管理器)**:统一管理所有 BehaviorTreeData
|
||||
|
||||
### 基本使用
|
||||
|
||||
```typescript
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
import {
|
||||
BehaviorTreeAssetManager,
|
||||
BehaviorTreeBuilder,
|
||||
BehaviorTreeStarter
|
||||
} from '@esengine/behavior-tree';
|
||||
|
||||
// 1. 获取资产管理器(插件已自动注册)
|
||||
const assetManager = Core.services.resolve(BehaviorTreeAssetManager);
|
||||
|
||||
// 2. 创建并注册行为树资产
|
||||
const enemyAI = BehaviorTreeBuilder.create('EnemyAI')
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.selector('MainBehavior')
|
||||
.log('攻击')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
assetManager.loadAsset(enemyAI);
|
||||
|
||||
// 3. 为多个实体使用同一份资产
|
||||
const enemy1 = scene.createEntity('Enemy1');
|
||||
const enemy2 = scene.createEntity('Enemy2');
|
||||
const enemy3 = scene.createEntity('Enemy3');
|
||||
|
||||
// 获取共享的资产
|
||||
const sharedTree = assetManager.getAsset('EnemyAI');
|
||||
|
||||
if (sharedTree) {
|
||||
BehaviorTreeStarter.start(enemy1, sharedTree);
|
||||
BehaviorTreeStarter.start(enemy2, sharedTree);
|
||||
BehaviorTreeStarter.start(enemy3, sharedTree);
|
||||
}
|
||||
```
|
||||
|
||||
### 资产管理器 API
|
||||
|
||||
```typescript
|
||||
// 加载资产
|
||||
assetManager.loadAsset(treeData);
|
||||
|
||||
// 获取资产
|
||||
const tree = assetManager.getAsset('TreeID');
|
||||
|
||||
// 检查资产是否存在
|
||||
if (assetManager.hasAsset('TreeID')) {
|
||||
// ...
|
||||
}
|
||||
|
||||
// 卸载资产
|
||||
assetManager.unloadAsset('TreeID');
|
||||
|
||||
// 获取所有资产ID
|
||||
const allIds = assetManager.getAllAssetIds();
|
||||
|
||||
// 清空所有资产
|
||||
assetManager.clearAll();
|
||||
```
|
||||
|
||||
## 从文件加载行为树
|
||||
|
||||
### JSON 格式
|
||||
|
||||
行为树可以导出为 JSON 格式:
|
||||
|
||||
```json
|
||||
{
|
||||
"version": "1.0.0",
|
||||
"metadata": {
|
||||
"name": "EnemyAI",
|
||||
"description": "敌人AI行为树"
|
||||
},
|
||||
"rootNodeId": "root-1",
|
||||
"nodes": [
|
||||
{
|
||||
"id": "root-1",
|
||||
"name": "RootSelector",
|
||||
"nodeType": "Composite",
|
||||
"data": {
|
||||
"compositeType": "Selector"
|
||||
},
|
||||
"children": ["combat-1", "patrol-1"]
|
||||
},
|
||||
{
|
||||
"id": "combat-1",
|
||||
"name": "Combat",
|
||||
"nodeType": "Action",
|
||||
"data": {
|
||||
"actionType": "LogAction",
|
||||
"message": "攻击敌人"
|
||||
},
|
||||
"children": []
|
||||
}
|
||||
],
|
||||
"blackboard": [
|
||||
{
|
||||
"name": "health",
|
||||
"type": "number",
|
||||
"defaultValue": 100
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### 加载 JSON 文件
|
||||
|
||||
```typescript
|
||||
import {
|
||||
BehaviorTreeAssetSerializer,
|
||||
BehaviorTreeAssetManager
|
||||
} from '@esengine/behavior-tree';
|
||||
|
||||
async function loadTreeFromFile(filePath: string) {
|
||||
const assetManager = Core.services.resolve(BehaviorTreeAssetManager);
|
||||
|
||||
// 1. 读取文件内容
|
||||
const jsonContent = await fetch(filePath).then(res => res.text());
|
||||
|
||||
// 2. 反序列化
|
||||
const treeData = BehaviorTreeAssetSerializer.deserialize(jsonContent);
|
||||
|
||||
// 3. 加载到资产管理器
|
||||
assetManager.loadAsset(treeData);
|
||||
|
||||
return treeData;
|
||||
}
|
||||
|
||||
// 使用
|
||||
const tree = await loadTreeFromFile('/assets/enemy-ai.btree.json');
|
||||
BehaviorTreeStarter.start(entity, tree);
|
||||
```
|
||||
|
||||
## 子树(SubTree)
|
||||
|
||||
子树允许你将常用的行为片段做成独立的树,然后在其他树中引用。
|
||||
|
||||
### 为什么使用子树?
|
||||
|
||||
1. **代码复用** - 避免重复定义相同的行为
|
||||
2. **模块化** - 将复杂的行为树拆分成小的可管理单元
|
||||
3. **团队协作** - 不同成员可以独立开发不同的子树
|
||||
|
||||
### 创建子树
|
||||
|
||||
```typescript
|
||||
// 1. 创建巡逻子树
|
||||
const patrolTree = BehaviorTreeBuilder.create('PatrolBehavior')
|
||||
.sequence('Patrol')
|
||||
.log('选择巡逻点', 'PickWaypoint')
|
||||
.log('移动到巡逻点', 'MoveToWaypoint')
|
||||
.wait(2.0, 'WaitAtWaypoint')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
// 2. 创建追击子树
|
||||
const chaseTree = BehaviorTreeBuilder.create('ChaseBehavior')
|
||||
.sequence('Chase')
|
||||
.log('锁定目标', 'LockTarget')
|
||||
.log('追击目标', 'ChaseTarget')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
// 3. 注册子树到资产管理器
|
||||
const assetManager = Core.services.resolve(BehaviorTreeAssetManager);
|
||||
assetManager.loadAsset(patrolTree);
|
||||
assetManager.loadAsset(chaseTree);
|
||||
```
|
||||
|
||||
### 使用子树
|
||||
|
||||
```typescript
|
||||
// 在主行为树中使用子树
|
||||
const mainTree = BehaviorTreeBuilder.create('EnemyAI')
|
||||
.defineBlackboardVariable('hasTarget', false)
|
||||
|
||||
.selector('MainBehavior')
|
||||
// 条件:发现目标时执行追击子树
|
||||
.sequence('CombatBranch')
|
||||
.blackboardExists('hasTarget')
|
||||
.subTree('ChaseBehavior', { shareBlackboard: true })
|
||||
.end()
|
||||
|
||||
// 默认:执行巡逻子树
|
||||
.subTree('PatrolBehavior', { shareBlackboard: true })
|
||||
.end()
|
||||
.build();
|
||||
|
||||
assetManager.loadAsset(mainTree);
|
||||
|
||||
// 启动主行为树
|
||||
const enemy = scene.createEntity('Enemy');
|
||||
BehaviorTreeStarter.start(enemy, mainTree);
|
||||
```
|
||||
|
||||
### SubTree 配置选项
|
||||
|
||||
```typescript
|
||||
.subTree('SubTreeID', {
|
||||
shareBlackboard: true, // 是否共享黑板(默认true)
|
||||
})
|
||||
```
|
||||
|
||||
- **shareBlackboard: true** - 子树和父树共享黑板变量
|
||||
- **shareBlackboard: false** - 子树使用独立的黑板
|
||||
|
||||
## 资源预加载
|
||||
|
||||
在游戏启动时预加载所有行为树资产:
|
||||
|
||||
```typescript
|
||||
class BehaviorTreePreloader {
|
||||
private assetManager: BehaviorTreeAssetManager;
|
||||
|
||||
constructor() {
|
||||
this.assetManager = Core.services.resolve(BehaviorTreeAssetManager);
|
||||
}
|
||||
|
||||
async preloadAll() {
|
||||
// 定义所有行为树文件
|
||||
const treeFiles = [
|
||||
'/assets/ai/enemy-ai.btree.json',
|
||||
'/assets/ai/boss-ai.btree.json',
|
||||
'/assets/ai/patrol.btree.json',
|
||||
'/assets/ai/chase.btree.json'
|
||||
];
|
||||
|
||||
// 并行加载所有文件
|
||||
const loadPromises = treeFiles.map(file => this.loadTree(file));
|
||||
await Promise.all(loadPromises);
|
||||
|
||||
console.log(`已加载 ${this.assetManager.getAssetCount()} 个行为树资产`);
|
||||
}
|
||||
|
||||
private async loadTree(filePath: string) {
|
||||
const jsonContent = await fetch(filePath).then(res => res.text());
|
||||
const treeData = BehaviorTreeAssetSerializer.deserialize(jsonContent);
|
||||
this.assetManager.loadAsset(treeData);
|
||||
}
|
||||
}
|
||||
|
||||
// 游戏启动时调用
|
||||
const preloader = new BehaviorTreePreloader();
|
||||
await preloader.preloadAll();
|
||||
```
|
||||
|
||||
## 运行时切换行为树
|
||||
|
||||
敌人在不同阶段使用不同的行为树:
|
||||
|
||||
```typescript
|
||||
class EnemyAI {
|
||||
private entity: Entity;
|
||||
private assetManager: BehaviorTreeAssetManager;
|
||||
|
||||
constructor(entity: Entity) {
|
||||
this.entity = entity;
|
||||
this.assetManager = Core.services.resolve(BehaviorTreeAssetManager);
|
||||
}
|
||||
|
||||
// 切换到巡逻AI
|
||||
switchToPatrol() {
|
||||
const tree = this.assetManager.getAsset('PatrolAI');
|
||||
if (tree) {
|
||||
BehaviorTreeStarter.stop(this.entity);
|
||||
BehaviorTreeStarter.start(this.entity, tree);
|
||||
}
|
||||
}
|
||||
|
||||
// 切换到战斗AI
|
||||
switchToCombat() {
|
||||
const tree = this.assetManager.getAsset('CombatAI');
|
||||
if (tree) {
|
||||
BehaviorTreeStarter.stop(this.entity);
|
||||
BehaviorTreeStarter.start(this.entity, tree);
|
||||
}
|
||||
}
|
||||
|
||||
// 切换到狂暴模式
|
||||
switchToBerserk() {
|
||||
const tree = this.assetManager.getAsset('BerserkAI');
|
||||
if (tree) {
|
||||
BehaviorTreeStarter.stop(this.entity);
|
||||
BehaviorTreeStarter.start(this.entity, tree);
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// 使用
|
||||
const enemyAI = new EnemyAI(enemyEntity);
|
||||
|
||||
// Boss血量低于30%时进入狂暴
|
||||
const runtime = enemyEntity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
const health = runtime?.getBlackboardValue<number>('health');
|
||||
|
||||
if (health && health < 30) {
|
||||
enemyAI.switchToBerserk();
|
||||
}
|
||||
```
|
||||
|
||||
## 内存优化
|
||||
|
||||
### 1. 共享行为树数据
|
||||
|
||||
```typescript
|
||||
// 好的做法:100个敌人共享1份BehaviorTreeData
|
||||
const sharedTree = assetManager.getAsset('EnemyAI');
|
||||
|
||||
for (let i = 0; i < 100; i++) {
|
||||
const enemy = scene.createEntity(`Enemy${i}`);
|
||||
BehaviorTreeStarter.start(enemy, sharedTree!); // 共享数据
|
||||
}
|
||||
|
||||
// 不好的做法:每个敌人创建独立的BehaviorTreeData
|
||||
for (let i = 0; i < 100; i++) {
|
||||
const enemy = scene.createEntity(`Enemy${i}`);
|
||||
const tree = BehaviorTreeBuilder.create('EnemyAI') // 重复创建
|
||||
// ... 节点定义
|
||||
.build();
|
||||
BehaviorTreeStarter.start(enemy, tree);
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 及时卸载不用的资产
|
||||
|
||||
```typescript
|
||||
// 关卡结束时卸载该关卡的AI
|
||||
function onLevelEnd() {
|
||||
assetManager.unloadAsset('Level1BossAI');
|
||||
assetManager.unloadAsset('Level1EnemyAI');
|
||||
}
|
||||
|
||||
// 加载新关卡的AI
|
||||
function onLevelStart() {
|
||||
const boss2AI = await loadTreeFromFile('/assets/level2-boss.btree.json');
|
||||
assetManager.loadAsset(boss2AI);
|
||||
}
|
||||
```
|
||||
|
||||
## 完整示例:多敌人类型的游戏
|
||||
|
||||
```typescript
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
import {
|
||||
BehaviorTreePlugin,
|
||||
BehaviorTreeAssetManager,
|
||||
BehaviorTreeBuilder,
|
||||
BehaviorTreeStarter
|
||||
} from '@esengine/behavior-tree';
|
||||
|
||||
async function setupGame() {
|
||||
// 1. 初始化
|
||||
Core.create();
|
||||
const plugin = new BehaviorTreePlugin();
|
||||
await Core.installPlugin(plugin);
|
||||
|
||||
const scene = new Scene();
|
||||
plugin.setupScene(scene);
|
||||
Core.setScene(scene);
|
||||
|
||||
const assetManager = Core.services.resolve(BehaviorTreeAssetManager);
|
||||
|
||||
// 2. 创建共享的子树
|
||||
const patrolTree = BehaviorTreeBuilder.create('Patrol')
|
||||
.sequence('PatrolLoop')
|
||||
.log('巡逻')
|
||||
.wait(1.0)
|
||||
.end()
|
||||
.build();
|
||||
|
||||
const combatTree = BehaviorTreeBuilder.create('Combat')
|
||||
.sequence('CombatLoop')
|
||||
.log('战斗')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
assetManager.loadAsset(patrolTree);
|
||||
assetManager.loadAsset(combatTree);
|
||||
|
||||
// 3. 创建不同类型敌人的AI
|
||||
const meleeEnemyAI = BehaviorTreeBuilder.create('MeleeEnemyAI')
|
||||
.selector('MeleeBehavior')
|
||||
.sequence('Attack')
|
||||
.blackboardExists('target')
|
||||
.log('近战攻击')
|
||||
.end()
|
||||
.subTree('Patrol')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
const rangedEnemyAI = BehaviorTreeBuilder.create('RangedEnemyAI')
|
||||
.selector('RangedBehavior')
|
||||
.sequence('Attack')
|
||||
.blackboardExists('target')
|
||||
.log('远程攻击')
|
||||
.end()
|
||||
.subTree('Patrol')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
assetManager.loadAsset(meleeEnemyAI);
|
||||
assetManager.loadAsset(rangedEnemyAI);
|
||||
|
||||
// 4. 创建多个敌人实体
|
||||
// 10个近战敌人共享同一份AI
|
||||
const meleeAI = assetManager.getAsset('MeleeEnemyAI')!;
|
||||
for (let i = 0; i < 10; i++) {
|
||||
const enemy = scene.createEntity(`MeleeEnemy${i}`);
|
||||
BehaviorTreeStarter.start(enemy, meleeAI);
|
||||
}
|
||||
|
||||
// 5个远程敌人共享同一份AI
|
||||
const rangedAI = assetManager.getAsset('RangedEnemyAI')!;
|
||||
for (let i = 0; i < 5; i++) {
|
||||
const enemy = scene.createEntity(`RangedEnemy${i}`);
|
||||
BehaviorTreeStarter.start(enemy, rangedAI);
|
||||
}
|
||||
|
||||
console.log(`已创建 15 个敌人,使用 ${assetManager.getAssetCount()} 个行为树资产`);
|
||||
|
||||
// 5. 游戏循环
|
||||
setInterval(() => {
|
||||
Core.update(0.016);
|
||||
}, 16);
|
||||
}
|
||||
|
||||
setupGame();
|
||||
```
|
||||
|
||||
## 常见问题
|
||||
|
||||
### 如何检查资产是否已加载?
|
||||
|
||||
```typescript
|
||||
const assetManager = Core.services.resolve(BehaviorTreeAssetManager);
|
||||
|
||||
if (!assetManager.hasAsset('EnemyAI')) {
|
||||
// 加载资产
|
||||
const tree = await loadTreeFromFile('/assets/enemy-ai.btree.json');
|
||||
assetManager.loadAsset(tree);
|
||||
}
|
||||
```
|
||||
|
||||
### 子树找不到怎么办?
|
||||
|
||||
确保子树已经加载到资产管理器中:
|
||||
|
||||
```typescript
|
||||
// 1. 先加载子树
|
||||
const subTree = BehaviorTreeBuilder.create('SubTreeID')
|
||||
// ...
|
||||
.build();
|
||||
assetManager.loadAsset(subTree);
|
||||
|
||||
// 2. 再加载使用子树的主树
|
||||
const mainTree = BehaviorTreeBuilder.create('MainTree')
|
||||
.subTree('SubTreeID')
|
||||
.build();
|
||||
```
|
||||
|
||||
### 如何导出行为树为 JSON?
|
||||
|
||||
```typescript
|
||||
import { BehaviorTreeAssetSerializer } from '@esengine/behavior-tree';
|
||||
|
||||
const tree = BehaviorTreeBuilder.create('MyTree')
|
||||
// ... 节点定义
|
||||
.build();
|
||||
|
||||
// 序列化为JSON字符串
|
||||
const json = BehaviorTreeAssetSerializer.serialize(tree);
|
||||
|
||||
// 保存到文件或发送到服务器
|
||||
console.log(json);
|
||||
```

# 最佳实践
|
||||
|
||||
本文介绍行为树设计和使用的最佳实践,帮助你构建高效、可维护的AI系统。
|
||||
|
||||
## 行为树设计原则
|
||||
|
||||
### 1. 保持树的层次清晰
|
||||
|
||||
将复杂行为分解成清晰的层次结构:
|
||||
|
||||
```
|
||||
Root Selector
|
||||
├── Emergency (高优先级:紧急情况)
|
||||
│ ├── FleeFromDanger
|
||||
│ └── CallForHelp
|
||||
├── Combat (中优先级:战斗)
|
||||
│ ├── Attack
|
||||
│ └── Defend
|
||||
└── Idle (低优先级:空闲)
|
||||
├── Patrol
|
||||
└── Rest
|
||||
```
|
||||
|
||||
|
||||
### 2. 单一职责原则
|
||||
|
||||
每个节点应该只做一件事。要实现复杂动作,创建自定义执行器,参见[自定义节点执行器](./custom-actions.md)。
|
||||
|
||||
```typescript
|
||||
// 好的设计 - 使用内置节点
|
||||
.sequence('AttackSequence')
|
||||
.blackboardExists('target', 'CheckTarget')
|
||||
.log('瞄准', 'Aim')
|
||||
.log('开火', 'Fire')
|
||||
.end()
|
||||
```
|
||||
|
||||
### 3. 使用描述性名称
|
||||
|
||||
节点名称应该清楚地表达其功能:
|
||||
|
||||
```typescript
|
||||
// 好的命名
|
||||
.blackboardCompare('health', 20, 'less', 'CheckHealthLow')
|
||||
.log('寻找最近的医疗包', 'FindHealthPack')
|
||||
.log('移动到医疗包', 'MoveToHealthPack')
|
||||
|
||||
// 不好的命名
|
||||
.blackboardCompare('health', 20, 'less', 'C1')
|
||||
.log('Do something', 'Action1')
|
||||
.log('Move', 'A2')
|
||||
```
|
||||
|
||||
## 黑板变量管理
|
||||
|
||||
### 1. 变量命名规范
|
||||
|
||||
使用清晰的命名约定:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('AI')
|
||||
// 状态变量
|
||||
.defineBlackboardVariable('currentState', 'idle')
|
||||
.defineBlackboardVariable('isMoving', false)
|
||||
|
||||
// 目标和引用
|
||||
.defineBlackboardVariable('targetEnemy', null)
|
||||
.defineBlackboardVariable('patrolPoints', [])
|
||||
|
||||
// 配置参数
|
||||
.defineBlackboardVariable('attackRange', 5.0)
|
||||
.defineBlackboardVariable('moveSpeed', 10.0)
|
||||
|
||||
// 临时数据
|
||||
.defineBlackboardVariable('lastAttackTime', 0)
|
||||
.defineBlackboardVariable('searchAttempts', 0)
|
||||
// ...
|
||||
.build();
|
||||
```
|
||||
|
||||
### 2. 避免过度使用黑板
|
||||
|
||||
只在需要跨节点共享的数据才放入黑板。在自定义执行器中使用局部变量:
|
||||
|
||||
```typescript
|
||||
// 好的做法 - 使用局部变量
|
||||
export class CalculateAction implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
// 局部计算
|
||||
const temp1 = 10;
|
||||
const temp2 = 20;
|
||||
const result = temp1 + temp2;
|
||||
|
||||
// 只保存需要共享的结果
|
||||
context.runtime.setBlackboardValue('calculationResult', result);
|
||||
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 使用类型安全的访问
|
||||
|
||||
```typescript
|
||||
export class TypeSafeAction implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const { runtime } = context;
|
||||
|
||||
// 使用泛型进行类型安全访问
|
||||
const health = runtime.getBlackboardValue<number>('health');
|
||||
const target = runtime.getBlackboardValue<Entity | null>('target');
|
||||
const state = runtime.getBlackboardValue<string>('currentState');
|
||||
|
||||
if (health !== undefined && health < 30) {
|
||||
runtime.setBlackboardValue('currentState', 'flee');
|
||||
}
|
||||
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 执行器设计
|
||||
|
||||
### 1. 保持执行器无状态
|
||||
|
||||
状态必须存储在`context.state`中,而不是执行器实例:
|
||||
|
||||
```typescript
|
||||
// 正确的做法
|
||||
export class TimedAction implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
if (!context.state.startTime) {
|
||||
context.state.startTime = context.totalTime;
|
||||
}
|
||||
|
||||
const elapsed = context.totalTime - context.state.startTime;
|
||||
|
||||
if (elapsed >= 3.0) {
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
|
||||
return TaskStatus.Running;
|
||||
}
|
||||
|
||||
reset(context: NodeExecutionContext): void {
|
||||
context.state.startTime = undefined;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 条件应该是无副作用的
|
||||
|
||||
条件检查不应该修改状态:
|
||||
|
||||
```typescript
|
||||
// 好的做法 - 只读检查
|
||||
@NodeExecutorMetadata({
|
||||
implementationType: 'IsHealthLow',
|
||||
nodeType: NodeType.Condition,
|
||||
displayName: '检查生命值低',
|
||||
category: '条件',
|
||||
configSchema: {
|
||||
threshold: {
|
||||
type: 'number',
|
||||
default: 30,
|
||||
supportBinding: true
|
||||
}
|
||||
}
|
||||
})
|
||||
export class IsHealthLow implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const threshold = BindingHelper.getValue<number>(context, 'threshold', 30);
|
||||
const health = context.runtime.getBlackboardValue<number>('health') || 0;
|
||||
|
||||
return health < threshold ? TaskStatus.Success : TaskStatus.Failure;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 错误处理
|
||||
|
||||
```typescript
|
||||
export class SafeAction implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
try {
|
||||
const resourceId = context.runtime.getBlackboardValue('resourceId');
|
||||
|
||||
if (!resourceId) {
|
||||
console.error('[SafeAction] 资源ID未设置');
|
||||
return TaskStatus.Failure;
|
||||
}
|
||||
|
||||
// 执行操作...
|
||||
|
||||
return TaskStatus.Success;
|
||||
|
||||
} catch (error) {
|
||||
console.error('[SafeAction] 执行失败:', error);
|
||||
context.runtime.setBlackboardValue('lastError', error.message);
|
||||
return TaskStatus.Failure;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 性能优化技巧
|
||||
|
||||
### 1. 使用冷却装饰器
|
||||
|
||||
避免高频执行昂贵操作:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('ThrottledAI')
|
||||
.cooldown(1.0, 'ThrottleSearch') // 最多每秒执行一次
|
||||
.log('昂贵的搜索操作', 'ExpensiveSearch')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 2. 缓存计算结果
|
||||
|
||||
```typescript
|
||||
export class CachedFindNearest implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const { state, runtime, totalTime } = context;
|
||||
|
||||
// 检查缓存是否有效
|
||||
const cacheTime = state.enemyCacheTime || 0;
|
||||
|
||||
if (totalTime - cacheTime < 0.5) { // 缓存0.5秒
|
||||
const cached = runtime.getBlackboardValue('nearestEnemy');
|
||||
return cached ? TaskStatus.Success : TaskStatus.Failure;
|
||||
}
|
||||
|
||||
// 执行搜索
|
||||
const nearest = findNearestEnemy();
|
||||
runtime.setBlackboardValue('nearestEnemy', nearest);
|
||||
state.enemyCacheTime = totalTime;
|
||||
|
||||
return nearest ? TaskStatus.Success : TaskStatus.Failure;
|
||||
}
|
||||
|
||||
reset(context: NodeExecutionContext): void {
|
||||
context.state.enemyCacheTime = undefined;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 使用早期退出
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('EarlyExit')
|
||||
.selector('FindTarget')
|
||||
// 先检查缓存的目标
|
||||
.blackboardExists('cachedTarget', 'HasCachedTarget')
|
||||
|
||||
// 没有缓存才进行搜索(需要自定义执行器)
|
||||
.log('执行昂贵的搜索', 'SearchNewTarget')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
## 可维护性
|
||||
|
||||
### 1. 使用有意义的节点名称
|
||||
|
||||
```typescript
|
||||
// 好的做法
|
||||
const tree = BehaviorTreeBuilder.create('CombatAI')
|
||||
.selector('CombatDecision')
|
||||
.sequence('AttackEnemy')
|
||||
.blackboardExists('target', 'HasTarget')
|
||||
.log('执行攻击', 'Attack')
|
||||
.end()
|
||||
.end()
|
||||
.build();
|
||||
|
||||
// 不好的做法
|
||||
const tree = BehaviorTreeBuilder.create('AI')
|
||||
.selector('Node1')
|
||||
.sequence('Node2')
|
||||
.blackboardExists('target', 'Node3')
|
||||
.log('Attack', 'Node4')
|
||||
.end()
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 2. 使用编辑器创建复杂树
|
||||
|
||||
对于复杂的AI,使用可视化编辑器:
|
||||
|
||||
- 更直观的结构
|
||||
- 方便非程序员调整
|
||||
- 易于版本控制
|
||||
- 支持实时调试
|
||||
|
||||
|
||||
### 3. 添加注释和文档
|
||||
|
||||
```typescript
|
||||
// 为行为树添加清晰的注释
|
||||
const bossAI = BehaviorTreeBuilder.create('BossAI')
|
||||
.defineBlackboardVariable('phase', 1) // 1=正常, 2=狂暴, 3=濒死
|
||||
|
||||
.selector('MainBehavior')
|
||||
// 阶段3: 生命值<20%,使用终极技能
|
||||
.sequence('Phase3')
|
||||
.blackboardCompare('phase', 3, 'equals')
|
||||
.log('使用终极技能', 'UltimateAbility')
|
||||
.end()
|
||||
|
||||
// 阶段2: 生命值<50%,进入狂暴
|
||||
.sequence('Phase2')
|
||||
.blackboardCompare('phase', 2, 'equals')
|
||||
.log('进入狂暴模式', 'BerserkMode')
|
||||
.end()
|
||||
|
||||
// 阶段1: 正常战斗
|
||||
.sequence('Phase1')
|
||||
.log('普通攻击', 'NormalAttack')
|
||||
.end()
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
## 调试技巧
|
||||
|
||||
### 1. 使用日志节点
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('Debug')
|
||||
.log('开始攻击序列', 'StartAttack')
|
||||
.sequence('Attack')
|
||||
.log('检查目标', 'CheckTarget')
|
||||
.blackboardExists('target')
|
||||
.log('执行攻击', 'DoAttack')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 2. 在自定义执行器中调试
|
||||
|
||||
```typescript
|
||||
export class DebugAction implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const { nodeData, runtime, state } = context;
|
||||
|
||||
console.group(`[${nodeData.name}]`);
|
||||
console.log('配置:', nodeData.config);
|
||||
console.log('状态:', state);
|
||||
console.log('黑板:', runtime.getAllBlackboardVariables());
|
||||
console.log('活动节点:', Array.from(runtime.activeNodeIds));
|
||||
console.groupEnd();
|
||||
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 状态可视化
|
||||
|
||||
```typescript
|
||||
export class VisualizeState implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
if (process.env.NODE_ENV === 'development') {
|
||||
console.group('AI State');
|
||||
console.log('Entity:', context.entity.name);
|
||||
console.log('Health:', context.runtime.getBlackboardValue('health'));
|
||||
console.log('State:', context.runtime.getBlackboardValue('currentState'));
|
||||
console.log('Target:', context.runtime.getBlackboardValue('target'));
|
||||
console.groupEnd();
|
||||
}
|
||||
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 常见反模式
|
||||
|
||||
### 1. 过深的嵌套
|
||||
|
||||
```typescript
|
||||
// 不好 - 太深的嵌套
|
||||
.selector()
|
||||
.sequence()
|
||||
.sequence()
|
||||
.sequence()
|
||||
.log('太深了', 'DeepAction')
|
||||
.end()
|
||||
.end()
|
||||
.end()
|
||||
.end()
|
||||
|
||||
// 好 - 使用合理的深度
|
||||
.selector()
|
||||
.sequence()
|
||||
.log('Action1')
|
||||
.log('Action2')
|
||||
.end()
|
||||
.sequence()
|
||||
.log('Action3')
|
||||
.log('Action4')
|
||||
.end()
|
||||
.end()
|
||||
```
|
||||
|
||||
### 2. 在执行器中存储状态
|
||||
|
||||
```typescript
|
||||
// 错误 - 状态存储在执行器中
|
||||
export class BadAction implements INodeExecutor {
|
||||
private startTime = 0; // 错误!多个节点会共享这个值
|
||||
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
this.startTime = context.totalTime; // 错误!
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
}
|
||||
|
||||
// 正确 - 状态存储在context.state中
|
||||
export class GoodAction implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
if (!context.state.startTime) {
|
||||
context.state.startTime = context.totalTime; // 正确!
|
||||
}
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 频繁修改黑板
|
||||
|
||||
```typescript
|
||||
// 不好 - 每帧都修改黑板
|
||||
export class FrequentUpdate implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const pos = getCurrentPosition();
|
||||
context.runtime.setBlackboardValue('position', pos); // 每帧都set
|
||||
context.runtime.setBlackboardValue('velocity', getVelocity());
|
||||
context.runtime.setBlackboardValue('rotation', getRotation());
|
||||
return TaskStatus.Running;
|
||||
}
|
||||
}
|
||||
|
||||
// 好 - 只在需要时修改
|
||||
export class SmartUpdate implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const oldPos = context.runtime.getBlackboardValue('position');
|
||||
const newPos = getCurrentPosition();
|
||||
|
||||
// 只在位置变化时更新
|
||||
if (!positionsEqual(oldPos, newPos)) {
|
||||
context.runtime.setBlackboardValue('position', newPos);
|
||||
}
|
||||
|
||||
return TaskStatus.Running;
|
||||
}
|
||||
}
|
||||
```
|
||||

||||
|
||||
- Cocos Creator 3.x 或更高版本
|
||||
- 基本的 TypeScript 知识
|
||||
- 已完成[快速开始](./getting-started.md)教程
|
||||
|
||||
## 安装
|
||||
|
||||
### 步骤1:安装依赖
|
||||
|
||||
在你的 Cocos Creator 项目根目录下:
|
||||
|
||||
```bash
|
||||
npm install @esengine/ecs-framework @esengine/behavior-tree
|
||||
```
|
||||
|
||||
### 步骤2:配置 tsconfig.json
|
||||
|
||||
确保 `tsconfig.json` 中包含以下配置:
|
||||
|
||||
```json
|
||||
{
|
||||
"compilerOptions": {
|
||||
"experimentalDecorators": true,
|
||||
"emitDecoratorMetadata": true,
|
||||
"moduleResolution": "node"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 项目结构
|
||||
|
||||
建议的项目结构:
|
||||
|
||||
```
|
||||
assets/
|
||||
├── scripts/
|
||||
│ ├── ai/
|
||||
│ │ ├── EnemyAIComponent.ts # AI 组件
|
||||
│ │ └── PlayerDetector.ts # 检测器
|
||||
│ ├── systems/
|
||||
│ │ └── BehaviorTreeSystem.ts # 行为树系统
|
||||
│ └── Main.ts # 主入口
|
||||
├── resources/
|
||||
│ └── behaviors/
|
||||
│ ├── enemy-ai.btree.json # 行为树资产
|
||||
│ └── patrol.btree.json # 子树资产
|
||||
└── types/
|
||||
└── enemy-ai.ts # 类型定义
|
||||
```
|
||||
|
||||
|
||||
## 初始化 ECS 和行为树
|
||||
|
||||
### 创建主入口组件
|
||||
|
||||
创建 `assets/scripts/Main.ts`:
|
||||
|
||||
```typescript
|
||||
import { _decorator, Component } from 'cc';
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
import { BehaviorTreePlugin } from '@esengine/behavior-tree';
|
||||
|
||||
const { ccclass } = _decorator;
|
||||
|
||||
@ccclass('Main')
|
||||
export class Main extends Component {
|
||||
async onLoad() {
|
||||
// 初始化 ECS Core
|
||||
Core.create();
|
||||
|
||||
// 安装行为树插件
|
||||
const behaviorTreePlugin = new BehaviorTreePlugin();
|
||||
await Core.installPlugin(behaviorTreePlugin);
|
||||
|
||||
// 创建并设置场景
|
||||
const scene = new Scene();
|
||||
behaviorTreePlugin.setupScene(scene);
|
||||
Core.setScene(scene);
|
||||
|
||||
console.log('ECS 和行为树系统初始化完成');
|
||||
}
|
||||
|
||||
update(deltaTime: number) {
|
||||
// 更新 ECS(会自动更新场景)
|
||||
Core.update(deltaTime);
|
||||
}
|
||||
|
||||
onDestroy() {
|
||||
// 清理资源
|
||||
Core.destroy();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
### 添加组件到场景
|
||||
|
||||
1. 在场景中创建一个空节点(命名为 `GameManager`)
|
||||
2. 添加 `Main` 组件到该节点
|
||||
|
||||
|
||||
## 创建 AI 组件
|
||||
|
||||
创建 `assets/scripts/ai/EnemyAIComponent.ts`:
|
||||
|
||||
```typescript
|
||||
import { _decorator, Component, Node } from 'cc';
|
||||
import { Core, Entity } from '@esengine/ecs-framework';
|
||||
import {
|
||||
BehaviorTreeBuilder,
|
||||
BehaviorTreeStarter,
|
||||
BehaviorTreeRuntimeComponent
|
||||
} from '@esengine/behavior-tree';
|
||||
|
||||
const { ccclass, property } = _decorator;
|
||||
|
||||
@ccclass('EnemyAIComponent')
|
||||
export class EnemyAIComponent extends Component {
|
||||
private aiEntity: Entity | null = null;
|
||||
|
||||
async start() {
|
||||
// 创建行为树
|
||||
await this.createBehaviorTree();
|
||||
}
|
||||
|
||||
private async createBehaviorTree() {
|
||||
try {
|
||||
// 获取Core管理的场景
|
||||
const scene = Core.scene;
|
||||
if (!scene) {
|
||||
console.error('场景未初始化');
|
||||
return;
|
||||
}
|
||||
|
||||
// 使用Builder API创建行为树
|
||||
const tree = BehaviorTreeBuilder.create('EnemyAI')
|
||||
.defineBlackboardVariable('cocosNode', this.node)
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.defineBlackboardVariable('playerNode', null)
|
||||
.defineBlackboardVariable('detectionRange', 10)
|
||||
.defineBlackboardVariable('attackRange', 2)
|
||||
.selector('MainBehavior')
|
||||
.sequence('Combat')
|
||||
.blackboardExists('playerNode')
|
||||
.blackboardCompare('health', 30, 'greater')
|
||||
.log('攻击玩家', 'AttackPlayer')
|
||||
.end()
|
||||
.sequence('Flee')
|
||||
.blackboardCompare('health', 30, 'lessOrEqual')
|
||||
.log('逃跑', 'RunAway')
|
||||
.end()
|
||||
.log('巡逻', 'Patrol')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
// 创建AI实体并启动
|
||||
this.aiEntity = scene.createEntity(`AI_${this.node.name}`);
|
||||
BehaviorTreeStarter.start(this.aiEntity, tree);
|
||||
|
||||
console.log('敌人 AI 已启动');
|
||||
} catch (error) {
|
||||
console.error('初始化行为树失败:', error);
|
||||
}
|
||||
}
|
||||
|
||||
onDestroy() {
|
||||
// 停止 AI
|
||||
if (this.aiEntity) {
|
||||
BehaviorTreeStarter.stop(this.aiEntity);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 与 Cocos 节点交互
|
||||
|
||||
### 创建自定义执行器
|
||||
|
||||
要实现与Cocos节点的交互,需要创建自定义执行器:
|
||||
|
||||
```typescript
|
||||
import {
|
||||
INodeExecutor,
|
||||
NodeExecutionContext,
|
||||
NodeExecutorMetadata
|
||||
} from '@esengine/behavior-tree';
|
||||
import { TaskStatus, NodeType } from '@esengine/behavior-tree';
|
||||
import { Animation } from 'cc';
|
||||
|
||||
@NodeExecutorMetadata({
|
||||
implementationType: 'PlayAnimation',
|
||||
nodeType: NodeType.Action,
|
||||
displayName: '播放动画',
|
||||
description: '播放Cocos节点上的动画',
|
||||
category: 'Cocos',
|
||||
configSchema: {
|
||||
animationName: {
|
||||
type: 'string',
|
||||
default: 'attack'
|
||||
}
|
||||
}
|
||||
})
|
||||
export class PlayAnimationAction implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const cocosNode = context.runtime.getBlackboardValue('cocosNode');
|
||||
const animationName = context.nodeData.config.animationName;
|
||||
|
||||
if (!cocosNode) {
|
||||
return TaskStatus.Failure;
|
||||
}
|
||||
|
||||
const animation = cocosNode.getComponent(Animation);
|
||||
if (animation) {
|
||||
animation.play(animationName);
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
|
||||
return TaskStatus.Failure;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 完整示例:敌人 AI
|
||||
|
||||
### 行为树设计
|
||||
|
||||
使用编辑器创建 `enemy-ai.btree.json`:
|
||||
|
||||
```
|
||||
RootSelector
|
||||
├── CombatSequence
|
||||
│ ├── CheckPlayerInRange (Condition)
|
||||
│ ├── CheckHealthGood (Condition)
|
||||
│ └── AttackPlayer (Action)
|
||||
├── FleeSequence
|
||||
│ ├── CheckHealthLow (Condition)
|
||||
│ └── RunAway (Action)
|
||||
└── PatrolSequence
|
||||
├── PickWaypoint (Action)
|
||||
├── MoveToWaypoint (Action)
|
||||
└── Wait (Action)
|
||||
```
|
||||
|
||||
|
||||
### 黑板变量
|
||||
|
||||
定义以下黑板变量:
|
||||
|
||||
- `cocosNode`:Node - Cocos 节点引用
|
||||
- `health`:Number - 生命值
|
||||
- `playerNode`:Object - 玩家节点引用
|
||||
- `detectionRange`:Number - 检测范围
|
||||
- `attackRange`:Number - 攻击范围
|
||||
- `currentWaypoint`:Number - 当前路点索引
|
||||
|
||||
|
||||
### 实现检测系统
|
||||
|
||||
创建 `assets/scripts/ai/PlayerDetector.ts`:
|
||||
|
||||
```typescript
|
||||
import { _decorator, Component, Node, Vec3 } from 'cc';
|
||||
import { BehaviorTreeRuntimeComponent } from '@esengine/behavior-tree';
|
||||
|
||||
const { ccclass, property } = _decorator;
|
||||
|
||||
@ccclass('PlayerDetector')
|
||||
export class PlayerDetector extends Component {
|
||||
@property(Node)
|
||||
player: Node = null;
|
||||
|
||||
@property
|
||||
detectionRange: number = 10;
|
||||
|
||||
private runtime: BehaviorTreeRuntimeComponent | null = null;
|
||||
|
||||
start() {
|
||||
// 假设AI组件在同一节点上
|
||||
const aiComponent = this.node.getComponent('EnemyAIComponent') as any;
|
||||
if (aiComponent && aiComponent.aiEntity) {
|
||||
this.runtime = aiComponent.aiEntity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
}
|
||||
}
|
||||
|
||||
update(deltaTime: number) {
|
||||
if (!this.runtime || !this.player) {
|
||||
return;
|
||||
}
|
||||
|
||||
// 计算距离
|
||||
const distance = Vec3.distance(this.node.position, this.player.position);
|
||||
|
||||
// 更新黑板
|
||||
this.runtime.setBlackboardValue('playerNode', this.player);
|
||||
this.runtime.setBlackboardValue('playerInRange', distance <= this.detectionRange);
|
||||
this.runtime.setBlackboardValue('distanceToPlayer', distance);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 资源管理
|
||||
|
||||
### 使用 BehaviorTreeAssetManager
|
||||
|
||||
框架提供了 `BehaviorTreeAssetManager` 来统一管理行为树资产,避免重复创建:
|
||||
|
||||
```typescript
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
import {
|
||||
BehaviorTreeAssetManager,
|
||||
BehaviorTreeBuilder,
|
||||
BehaviorTreeStarter
|
||||
} from '@esengine/behavior-tree';
|
||||
|
||||
// 获取资产管理器(插件已自动注册)
|
||||
const assetManager = Core.services.resolve(BehaviorTreeAssetManager);
|
||||
|
||||
// 创建并注册行为树(只创建一次)
|
||||
const enemyAI = BehaviorTreeBuilder.create('EnemyAI')
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.selector('MainBehavior')
|
||||
.log('攻击')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
assetManager.loadAsset(enemyAI);
|
||||
|
||||
// 为多个敌人实体使用同一份资产
|
||||
for (let i = 0; i < 10; i++) {
|
||||
const enemy = scene.createEntity(`Enemy${i}`);
|
||||
const tree = assetManager.getAsset('EnemyAI')!;
|
||||
BehaviorTreeStarter.start(enemy, tree); // 10个敌人共享1份数据
|
||||
}
|
||||
```
|
||||
|
||||
### 从 Cocos Creator 资源加载
|
||||
|
||||
#### 1. 将行为树 JSON 放入 resources 目录
|
||||
|
||||
```
|
||||
assets/
|
||||
└── resources/
|
||||
└── behaviors/
|
||||
├── enemy-ai.btree.json
|
||||
└── boss-ai.btree.json
|
||||
```
|
||||
|
||||
#### 2. 创建资源加载器
|
||||
|
||||
创建 `assets/scripts/BehaviorTreeLoader.ts`:
|
||||
|
||||
```typescript
|
||||
import { resources, JsonAsset } from 'cc';
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
import {
|
||||
BehaviorTreeAssetManager,
|
||||
BehaviorTreeAssetSerializer,
|
||||
BehaviorTreeData
|
||||
} from '@esengine/behavior-tree';
|
||||
|
||||
export class BehaviorTreeLoader {
|
||||
private assetManager: BehaviorTreeAssetManager;
|
||||
|
||||
constructor() {
|
||||
this.assetManager = Core.services.resolve(BehaviorTreeAssetManager);
|
||||
}
|
||||
|
||||
/**
|
||||
* 从 resources 目录加载行为树
|
||||
* @param path 相对于 resources 的路径,不带扩展名
|
||||
* @example await loader.load('behaviors/enemy-ai')
|
||||
*/
|
||||
async load(path: string): Promise<BehaviorTreeData | null> {
|
||||
return new Promise((resolve, reject) => {
|
||||
resources.load(path, JsonAsset, (err, jsonAsset) => {
|
||||
if (err) {
|
||||
console.error(`加载行为树失败: ${path}`, err);
|
||||
reject(err);
|
||||
return;
|
||||
}
|
||||
|
||||
try {
|
||||
// 反序列化 JSON 为 BehaviorTreeData
|
||||
const jsonStr = JSON.stringify(jsonAsset.json);
|
||||
const treeData = BehaviorTreeAssetSerializer.deserialize(jsonStr);
|
||||
|
||||
// 加载到资产管理器
|
||||
this.assetManager.loadAsset(treeData);
|
||||
|
||||
console.log(`行为树已加载: ${treeData.name}`);
|
||||
resolve(treeData);
|
||||
} catch (error) {
|
||||
console.error(`解析行为树失败: ${path}`, error);
|
||||
reject(error);
|
||||
}
|
||||
});
|
||||
});
|
||||
}
|
||||
|
||||
/**
|
||||
* 预加载所有行为树
|
||||
*/
|
||||
async preloadAll(paths: string[]): Promise<void> {
|
||||
const promises = paths.map(path => this.load(path));
|
||||
await Promise.all(promises);
|
||||
console.log(`已预加载 ${paths.length} 个行为树`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 3. 在游戏启动时预加载
|
||||
|
||||
修改 `Main.ts`:
|
||||
|
||||
```typescript
|
||||
import { _decorator, Component } from 'cc';
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
import { BehaviorTreePlugin } from '@esengine/behavior-tree';
|
||||
import { BehaviorTreeLoader } from './BehaviorTreeLoader';
|
||||
|
||||
const { ccclass } = _decorator;
|
||||
|
||||
@ccclass('Main')
|
||||
export class Main extends Component {
|
||||
private loader: BehaviorTreeLoader | null = null;
|
||||
|
||||
async onLoad() {
|
||||
// 初始化 ECS Core
|
||||
Core.create();
|
||||
|
||||
// 安装行为树插件
|
||||
const behaviorTreePlugin = new BehaviorTreePlugin();
|
||||
await Core.installPlugin(behaviorTreePlugin);
|
||||
|
||||
// 创建场景
|
||||
const scene = new Scene();
|
||||
behaviorTreePlugin.setupScene(scene);
|
||||
Core.setScene(scene);
|
||||
|
||||
// 创建加载器并预加载所有行为树
|
||||
this.loader = new BehaviorTreeLoader();
|
||||
await this.loader.preloadAll([
|
||||
'behaviors/enemy-ai',
|
||||
'behaviors/boss-ai',
|
||||
'behaviors/patrol', // 子树
|
||||
'behaviors/chase' // 子树
|
||||
]);
|
||||
|
||||
console.log('游戏初始化完成');
|
||||
}
|
||||
|
||||
update(deltaTime: number) {
|
||||
Core.update(deltaTime);
|
||||
}
|
||||
|
||||
onDestroy() {
|
||||
Core.destroy();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 4. 在敌人组件中使用
|
||||
|
||||
```typescript
|
||||
import { _decorator, Component } from 'cc';
|
||||
import { Core, Entity } from '@esengine/ecs-framework';
|
||||
import {
|
||||
BehaviorTreeAssetManager,
|
||||
BehaviorTreeStarter
|
||||
} from '@esengine/behavior-tree';
|
||||
|
||||
const { ccclass, property } = _decorator;
|
||||
|
||||
@ccclass('EnemyAIComponent')
|
||||
export class EnemyAIComponent extends Component {
|
||||
@property
|
||||
aiType: string = 'enemy-ai'; // 在编辑器中配置使用哪个AI
|
||||
|
||||
private aiEntity: Entity | null = null;
|
||||
|
||||
start() {
|
||||
const scene = Core.scene;
|
||||
if (!scene) return;
|
||||
|
||||
// 从资产管理器获取已加载的行为树
|
||||
const assetManager = Core.services.resolve(BehaviorTreeAssetManager);
|
||||
const tree = assetManager.getAsset(this.aiType);
|
||||
|
||||
if (tree) {
|
||||
this.aiEntity = scene.createEntity(`AI_${this.node.name}`);
|
||||
BehaviorTreeStarter.start(this.aiEntity, tree);
|
||||
|
||||
// 设置黑板变量
|
||||
const runtime = this.aiEntity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
runtime?.setBlackboardValue('cocosNode', this.node);
|
||||
} else {
|
||||
console.error(`找不到行为树资产: ${this.aiType}`);
|
||||
}
|
||||
}
|
||||
|
||||
onDestroy() {
|
||||
if (this.aiEntity) {
|
||||
BehaviorTreeStarter.stop(this.aiEntity);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 调试
|
||||
|
||||
### 可视化调试信息
|
||||
|
||||
创建调试组件显示 AI 状态:
|
||||
|
||||
```typescript
|
||||
import { _decorator, Component, Label } from 'cc';
|
||||
import { BehaviorTreeRuntimeComponent } from '@esengine/behavior-tree';
|
||||
|
||||
const { ccclass, property } = _decorator;
|
||||
|
||||
@ccclass('AIDebugger')
|
||||
export class AIDebugger extends Component {
|
||||
@property(Label)
|
||||
debugLabel: Label = null;
|
||||
|
||||
private runtime: BehaviorTreeRuntimeComponent | null = null;
|
||||
|
||||
start() {
|
||||
const aiComponent = this.node.getComponent('EnemyAIComponent') as any;
|
||||
if (aiComponent && aiComponent.aiEntity) {
|
||||
this.runtime = aiComponent.aiEntity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
}
|
||||
}
|
||||
|
||||
update() {
|
||||
if (!this.runtime || !this.debugLabel) {
|
||||
return;
|
||||
}
|
||||
|
||||
const health = this.runtime.getBlackboardValue('health');
|
||||
const playerNode = this.runtime.getBlackboardValue('playerNode');
|
||||
|
||||
this.debugLabel.string = `Health: ${health}\nHas Target: ${playerNode ? 'Yes' : 'No'}`;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 性能优化
|
||||
|
||||
### 1. 限制行为树数量
|
||||
|
||||
合理控制同时运行的行为树数量:
|
||||
|
||||
```typescript
|
||||
class AIManager {
|
||||
private activeAIs: Entity[] = [];
|
||||
private maxAIs: number = 20;
|
||||
|
||||
addAI(entity: Entity, tree: BehaviorTreeData) {
|
||||
if (this.activeAIs.length >= this.maxAIs) {
|
||||
// 移除最远的AI
|
||||
const furthest = this.findFurthestAI();
|
||||
if (furthest) {
|
||||
BehaviorTreeStarter.stop(furthest);
|
||||
this.activeAIs = this.activeAIs.filter(e => e !== furthest);
|
||||
}
|
||||
}
|
||||
|
||||
BehaviorTreeStarter.start(entity, tree);
|
||||
this.activeAIs.push(entity);
|
||||
}
|
||||
|
||||
removeAI(entity: Entity) {
|
||||
BehaviorTreeStarter.stop(entity);
|
||||
this.activeAIs = this.activeAIs.filter(e => e !== entity);
|
||||
}
|
||||
|
||||
private findFurthestAI(): Entity | null {
|
||||
// 根据距离找到最远的AI
|
||||
// 实现细节略
|
||||
return this.activeAIs[0];
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 使用冷却装饰器
|
||||
|
||||
对于不需要每帧更新的AI,使用冷却装饰器:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('ThrottledAI')
|
||||
.cooldown(0.2, 'ThrottleRoot') // 每0.2秒执行一次
|
||||
.selector('MainBehavior')
|
||||
// AI逻辑...
|
||||
.end()
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 3. 缓存计算结果
|
||||
|
||||
在自定义执行器中缓存昂贵的计算:
|
||||
|
||||
```typescript
|
||||
export class CachedFindTarget implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const { state, runtime, totalTime } = context;
|
||||
const cacheTime = state.lastFindTime || 0;
|
||||
|
||||
if (totalTime - cacheTime < 1.0) {
|
||||
const cached = runtime.getBlackboardValue('target');
|
||||
return cached ? TaskStatus.Success : TaskStatus.Failure;
|
||||
}
|
||||
|
||||
const target = findNearestTarget();
|
||||
runtime.setBlackboardValue('target', target);
|
||||
state.lastFindTime = totalTime;
|
||||
|
||||
return target ? TaskStatus.Success : TaskStatus.Failure;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 多平台注意事项
|
||||
|
||||
### 性能考虑
|
||||
|
||||
不同平台的性能差异:
|
||||
|
||||
- **Web平台**: 受浏览器性能限制,建议减少同时运行的AI数量
|
||||
- **原生平台**: 性能较好,可以运行更多AI
|
||||
- **小游戏平台**: 内存受限,注意控制行为树数量和复杂度
|
||||
|
||||
### 平台适配
|
||||
|
||||
```typescript
|
||||
import { sys } from 'cc';
|
||||
|
||||
// 根据平台调整AI数量
|
||||
const maxAIs = sys.isNative ? 50 : (sys.isBrowser ? 20 : 30);
|
||||
|
||||
// 根据平台调整更新频率
|
||||
const updateInterval = sys.isNative ? 0.016 : 0.05;
|
||||
```
|
||||
|
||||
## 常见问题
|
||||
|
||||
### 行为树无法加载?
|
||||
|
||||
检查:
|
||||
1. 资源路径是否正确(相对于 `resources` 目录)
|
||||
2. 文件是否已添加到项目中
|
||||
3. 检查控制台错误信息
|
||||
|
||||
### AI 不执行?
|
||||
|
||||
确保:
|
||||
1. `Main` 组件的 `update` 方法被调用
|
||||
2. `Scene.update()` 在每帧被调用
|
||||
3. 行为树已通过 `BehaviorTreeStarter.start()` 启动
|
||||
|
||||
### 黑板变量不更新?
|
||||
|
||||
检查:
|
||||
1. 变量名拼写是否正确
|
||||
2. 是否在正确的时机更新变量
|
||||
3. 使用 `BehaviorTreeRuntimeComponent.getBlackboardValue()` 和 `setBlackboardValue()` 方法

# 核心概念
|
||||
|
||||
本文介绍行为树系统的核心概念和工作原理。
|
||||
|
||||
## 什么是行为树?
|
||||
|
||||
行为树(Behavior Tree)是一种用于控制AI和自动化系统的决策结构。它通过树状层次结构组织任务,从根节点开始逐层执行,直到找到合适的行为。
|
||||
|
||||
### 与状态机的对比
|
||||
|
||||
传统状态机:
|
||||
- 基于状态和转换
|
||||
- 状态之间的转换复杂
|
||||
- 难以扩展和维护
|
||||
- 不便于复用
|
||||
|
||||
行为树:
|
||||
- 基于任务和层次结构
|
||||
- 模块化、易于复用
|
||||
- 可视化编辑
|
||||
- 灵活的决策逻辑
|
||||
|
||||
|
||||
## 树结构
|
||||
|
||||
行为树由节点组成,形成树状结构:
|
||||
|
||||
```
|
||||
Root (根节点)
|
||||
├── Selector (选择器)
|
||||
│ ├── Sequence (序列)
|
||||
│ │ ├── Condition (条件)
|
||||
│ │ └── Action (动作)
|
||||
│ └── Action (动作)
|
||||
└── Sequence (序列)
|
||||
├── Action (动作)
|
||||
└── Wait (等待)
|
||||
```
|
||||
|
||||
每个节点都有:
|
||||
- 父节点(除了根节点)
|
||||
- 零个或多个子节点
|
||||
- 执行状态
|
||||
- 返回结果
|
||||
|
||||
|
||||
## 节点类型
|
||||
|
||||
### 复合节点(Composite)
|
||||
|
||||
复合节点有多个子节点,按特定规则执行它们。
|
||||
|
||||
#### Selector(选择器)
|
||||
|
||||
按顺序尝试执行子节点,直到某个子节点成功。
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('FindFood')
|
||||
.selector('FindFoodSelector')
|
||||
.log('尝试吃附近的食物', 'EatNearby')
|
||||
.log('搜索食物', 'SearchFood')
|
||||
.log('放弃', 'GiveUp')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
执行逻辑:
|
||||
1. 尝试第一个子节点
|
||||
2. 如果返回Success,选择器成功
|
||||
3. 如果返回Failure,尝试下一个子节点
|
||||
4. 如果返回Running,选择器返回Running
|
||||
5. 所有子节点都失败时,选择器失败
|
||||
|
||||
|
||||
#### Sequence(序列)
|
||||
|
||||
按顺序执行所有子节点,直到某个子节点失败。
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('Attack')
|
||||
.sequence('AttackSequence')
|
||||
.blackboardExists('target') // 检查是否有目标
|
||||
.log('瞄准', 'Aim')
|
||||
.log('开火', 'Fire')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
执行逻辑:
|
||||
1. 依次执行子节点
|
||||
2. 如果子节点返回Failure,序列失败
|
||||
3. 如果子节点返回Running,序列返回Running
|
||||
4. 如果子节点返回Success,继续下一个子节点
|
||||
5. 所有子节点都成功时,序列成功
|
||||
|
||||
|
||||
#### Parallel(并行)
|
||||
|
||||
同时执行多个子节点。
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('PlayEffects')
|
||||
.parallel('Effects', {
|
||||
successPolicy: 'all', // 所有任务都要成功
|
||||
failurePolicy: 'one' // 任一失败则失败
|
||||
})
|
||||
.log('播放动画', 'PlayAnimation')
|
||||
.log('播放音效', 'PlaySound')
|
||||
.log('生成粒子', 'SpawnEffect')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
策略类型:
|
||||
- `successPolicy: 'all'`: 所有子节点都成功才成功
|
||||
- `successPolicy: 'one'`: 任意一个子节点成功就成功
|
||||
- `failurePolicy: 'all'`: 所有子节点都失败才失败
|
||||
- `failurePolicy: 'one'`: 任意一个子节点失败就失败
|
||||
|
||||
|
||||
### 装饰器节点(Decorator)
|
||||
|
||||
装饰器节点只有一个子节点,用于修改子节点的行为或结果。
|
||||
|
||||
#### Inverter(反转)
|
||||
|
||||
反转子节点的结果:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('CheckSafe')
|
||||
.inverter('NotHasEnemy')
|
||||
.blackboardExists('enemy')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
#### Repeater(重复)
|
||||
|
||||
重复执行子节点:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('Jump3Times')
|
||||
.repeater(3, 'RepeatJump')
|
||||
.log('跳跃', 'Jump')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
#### Cooldown(冷却)
|
||||
|
||||
限制子节点的执行频率:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('UseSkill')
|
||||
.cooldown(5.0, 'SkillCooldown')
|
||||
.log('使用特殊技能', 'UseSpecialAbility')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
#### Timeout(超时)
|
||||
|
||||
限制子节点的执行时间:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('TimedTask')
|
||||
.timeout(10.0, 'TaskTimeout')
|
||||
.log('长时间运行的任务', 'ComplexTask')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
|
||||
### 叶节点(Leaf)
|
||||
|
||||
叶节点没有子节点,执行具体的任务。
|
||||
|
||||
#### Action(动作)
|
||||
|
||||
执行具体操作。内置动作节点包括:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('Actions')
|
||||
.sequence()
|
||||
.wait(2.0) // 等待2秒
|
||||
.log('Hello', 'LogAction') // 输出日志
|
||||
.setBlackboardValue('score', 100) // 设置黑板值
|
||||
.modifyBlackboardValue('score', 'add', 10) // 修改黑板值
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
要实现自定义动作,需要创建自定义执行器,参见[自定义节点执行器](./custom-actions.md)。
|
||||
|
||||
#### Condition(条件)
|
||||
|
||||
检查条件。内置条件节点包括:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('Conditions')
|
||||
.selector()
|
||||
.blackboardExists('player') // 检查变量是否存在
|
||||
.blackboardCompare('health', 50, 'greater') // 比较变量值
|
||||
.randomProbability(0.5) // 50%概率
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
#### Wait(等待)
|
||||
|
||||
等待指定时间:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('WaitExample')
|
||||
.wait(2.0, 'Wait2Seconds')
|
||||
.build();
|
||||
```
|
||||
|
||||
|
||||
## 任务状态
|
||||
|
||||
每个节点执行后返回以下状态之一:
|
||||
|
||||
### Success(成功)
|
||||
|
||||
任务成功完成。
|
||||
|
||||
```typescript
|
||||
// 内置节点会根据逻辑自动返回Success
|
||||
.log('任务完成') // 总是返回Success
|
||||
.blackboardCompare('score', 100, 'greater') // 条件满足时返回Success
|
||||
```
|
||||
|
||||
### Failure(失败)
|
||||
|
||||
任务执行失败。
|
||||
|
||||
```typescript
|
||||
.blackboardCompare('score', 100, 'greater') // 条件不满足返回Failure
|
||||
.blackboardExists('nonExistent') // 变量不存在返回Failure
|
||||
```
|
||||
|
||||
### Running(运行中)
|
||||
|
||||
任务需要多帧完成,仍在执行中。
|
||||
|
||||
```typescript
|
||||
.wait(3.0) // 等待过程中返回Running,3秒后返回Success
|
||||
```
|
||||
|
||||
### Invalid(无效)
|
||||
|
||||
节点未初始化或已重置。通常不需要手动处理此状态。
|
||||
|
||||
|
||||
## 黑板系统
|
||||
|
||||
黑板(Blackboard)是行为树的数据存储系统,用于在节点之间共享数据。
|
||||
|
||||
### 本地黑板
|
||||
|
||||
每个行为树实例都有自己的本地黑板:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('EnemyAI')
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.defineBlackboardVariable('target', null)
|
||||
.defineBlackboardVariable('state', 'idle')
|
||||
// ...
|
||||
.build();
|
||||
```
|
||||
|
||||
### 支持的数据类型
|
||||
|
||||
黑板支持以下数据类型:
|
||||
- String:字符串
|
||||
- Number:数字
|
||||
- Boolean:布尔值
|
||||
- Vector2:二维向量
|
||||
- Vector3:三维向量
|
||||
- Object:对象引用
|
||||
- Array:数组
|
||||
|
||||
示例:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('Variables')
|
||||
.defineBlackboardVariable('name', 'Enemy') // 字符串
|
||||
.defineBlackboardVariable('count', 0) // 数字
|
||||
.defineBlackboardVariable('isActive', true) // 布尔值
|
||||
.defineBlackboardVariable('position', { x: 0, y: 0 }) // 对象(也可用于Vector2)
|
||||
.defineBlackboardVariable('velocity', { x: 0, y: 0, z: 0 }) // 对象(也可用于Vector3)
|
||||
.defineBlackboardVariable('items', []) // 数组
|
||||
.build();
|
||||
```
|
||||
|
||||
### 读写变量
|
||||
|
||||
通过`BehaviorTreeRuntimeComponent`访问黑板:
|
||||
|
||||
```typescript
|
||||
const runtime = entity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
|
||||
// 读取变量
|
||||
const health = runtime?.getBlackboardValue('health');
|
||||
const target = runtime?.getBlackboardValue('target');
|
||||
|
||||
// 写入变量
|
||||
runtime?.setBlackboardValue('health', 50);
|
||||
runtime?.setBlackboardValue('lastAttackTime', Date.now());
|
||||
|
||||
// 获取所有变量
|
||||
const allVars = runtime?.getAllBlackboardVariables();
|
||||
```
|
||||
|
||||
也可以使用内置节点操作黑板:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('BlackboardOps')
|
||||
.sequence()
|
||||
.setBlackboardValue('score', 100) // 设置值
|
||||
.modifyBlackboardValue('score', 'add', 10) // 增加10
|
||||
.blackboardCompare('score', 110, 'equals') // 检查是否等于110
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 全局黑板
|
||||
|
||||
所有行为树实例共享的黑板,通过`GlobalBlackboardService`访问:
|
||||
|
||||
```typescript
|
||||
import { GlobalBlackboardService } from '@esengine/behavior-tree';
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
|
||||
const globalBlackboard = Core.services.resolve(GlobalBlackboardService);
|
||||
|
||||
// 设置全局变量
|
||||
globalBlackboard.setValue('gameState', 'playing');
|
||||
globalBlackboard.setValue('difficulty', 5);
|
||||
|
||||
// 读取全局变量
|
||||
const gameState = globalBlackboard.getValue('gameState');
|
||||
```
|
||||
|
||||
在自定义执行器中访问全局黑板:
|
||||
|
||||
```typescript
|
||||
import { GlobalBlackboardService } from '@esengine/behavior-tree';
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
|
||||
export class CheckGameState implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const globalBlackboard = Core.services.resolve(GlobalBlackboardService);
|
||||
const gameState = globalBlackboard.getValue('gameState');
|
||||
|
||||
if (gameState === 'paused') {
|
||||
return TaskStatus.Failure;
|
||||
}
|
||||
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 执行流程
|
||||
|
||||
### 初始化
|
||||
|
||||
```typescript
|
||||
// 1. 初始化Core和插件
|
||||
Core.create();
|
||||
const plugin = new BehaviorTreePlugin();
|
||||
await Core.installPlugin(plugin);
|
||||
|
||||
// 2. 创建场景
|
||||
const scene = new Scene();
|
||||
plugin.setupScene(scene);
|
||||
Core.setScene(scene);
|
||||
|
||||
// 3. 构建行为树
|
||||
const tree = BehaviorTreeBuilder.create('AI')
|
||||
// ... 定义节点
|
||||
.build();
|
||||
|
||||
// 4. 创建实体并启动
|
||||
const entity = scene.createEntity('AIEntity');
|
||||
BehaviorTreeStarter.start(entity, tree);
|
||||
```
|
||||
|
||||
### 更新循环
|
||||
|
||||
```typescript
|
||||
// 每帧更新
|
||||
gameLoop(() => {
|
||||
const deltaTime = getDeltaTime();
|
||||
Core.update(deltaTime); // Core会自动更新场景和所有行为树
|
||||
});
|
||||
```
|
||||
|
||||
### 执行顺序
|
||||
|
||||
```
|
||||
1. 从根节点开始
|
||||
2. 根节点执行其逻辑(通常是Selector或Sequence)
|
||||
3. 根节点的子节点按顺序执行
|
||||
4. 每个子节点可能有自己的子节点
|
||||
5. 叶节点执行具体操作并返回状态
|
||||
6. 状态向上传播到父节点
|
||||
7. 父节点根据策略决定如何处理子节点的状态
|
||||
8. 最终根节点返回整体状态
|
||||
```
|
||||
|
||||
### 执行示例
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('Example')
|
||||
.selector('Root') // 1. 执行选择器
|
||||
.sequence('Branch1') // 2. 尝试第一个分支
|
||||
.blackboardCompare('ready', true, 'equals', 'CheckReady') // 3. 条件失败
|
||||
.end() // 4. 序列失败,选择器继续下一个分支
|
||||
.sequence('Branch2') // 5. 尝试第二个分支
|
||||
.blackboardCompare('active', true, 'equals', 'CheckActive') // 6. 条件成功
|
||||
.log('执行动作', 'DoAction') // 7. 动作成功
|
||||
.end() // 8. 序列成功,选择器成功
|
||||
.end() // 9. 整个树成功
|
||||
.build();
|
||||
```
|
||||
|
||||
执行流程图:
|
||||
|
||||
```
|
||||
Root(Selector)
|
||||
→ Branch1(Sequence)
|
||||
→ CheckReady: Failure
|
||||
→ Branch1 fails
|
||||
→ Branch2(Sequence)
|
||||
→ CheckActive: Success
|
||||
→ DoAction: Success
|
||||
→ Branch2 succeeds
|
||||
→ Root succeeds
|
||||
```
|
||||
|
||||
|
||||
## Runtime架构
|
||||
|
||||
本框架的行为树采用Runtime执行器架构:
|
||||
|
||||
### 核心组件
|
||||
|
||||
- **BehaviorTreeData**: 纯数据结构,描述行为树的结构和配置
|
||||
- **BehaviorTreeRuntimeComponent**: 运行时组件,管理执行状态和黑板
|
||||
- **BehaviorTreeExecutionSystem**: 执行系统,驱动行为树运行
|
||||
- **INodeExecutor**: 节点执行器接口,定义节点的执行逻辑
|
||||
- **NodeExecutionContext**: 执行上下文,包含执行所需的所有信息
|
||||
|
||||
### 架构特点
|
||||
|
||||
1. **数据与逻辑分离**: BehaviorTreeData是纯数据,执行逻辑在执行器中
|
||||
2. **无状态执行器**: 执行器实例可以在多个节点间共享,状态存储在Runtime中
|
||||
3. **类型安全**: 通过TypeScript类型系统保证类型安全
|
||||
4. **高性能**: 避免不必要的对象创建,优化内存使用
|
||||
|
||||
### 数据流
|
||||
|
||||
```
|
||||
BehaviorTreeBuilder
|
||||
↓ (构建)
|
||||
BehaviorTreeData
|
||||
↓ (加载到)
|
||||
BehaviorTreeAssetManager
|
||||
↓ (读取)
|
||||
BehaviorTreeExecutionSystem
|
||||
↓ (执行)
|
||||
INodeExecutor.execute(context)
|
||||
↓ (返回)
|
||||
TaskStatus
|
||||
↓ (更新)
|
||||
NodeRuntimeState
|
||||
```
|
||||
|
||||
|
||||

# 行为树编辑器使用指南
|
||||
|
||||
行为树编辑器提供了可视化的方式来创建和编辑行为树。
|
||||
|
||||
## 启动编辑器
|
||||
|
||||
```bash
|
||||
cd packages/editor-app
|
||||
npm run tauri:dev
|
||||
```
|
||||
|
||||
## 基本操作
|
||||
|
||||
### 打开行为树编辑器
|
||||
|
||||
通过以下方式打开行为树编辑器窗口:
|
||||
|
||||
1. 在资产浏览器中双击 `.btree` 文件
|
||||
2. 菜单栏:`窗口` → 选择行为树编辑器相关插件
|
||||
|
||||
### 创建新行为树
|
||||
|
||||
在行为树编辑器窗口的工具栏中点击"新建"按钮(加号图标)
|
||||
|
||||
### 保存行为树
|
||||
|
||||
在行为树编辑器窗口的工具栏中点击"保存"按钮(磁盘图标)
|
||||
|
||||
### 添加节点
|
||||
|
||||
从左侧节点面板拖拽节点到画布:
|
||||
- 复合节点:Selector、Sequence、Parallel
|
||||
- 装饰器:Inverter、Repeater、UntilFail等
|
||||
- 动作节点:ExecuteAction、Wait等
|
||||
- 条件节点:Condition
|
||||
|
||||
### 连接节点
|
||||
|
||||
拖拽父节点底部的连接点到子节点顶部建立连接
|
||||
|
||||
### 删除节点
|
||||
|
||||
选中节点后按 `Delete` 或 `Backspace` 键
|
||||
|
||||
### 编辑属性
|
||||
|
||||
点击节点后在右侧属性面板中编辑节点参数
|
||||
|
||||
## 黑板变量
|
||||
|
||||
在黑板面板中管理共享数据:
|
||||
|
||||
1. 点击"添加变量"按钮
|
||||
2. 输入变量名、选择类型并设置默认值
|
||||
3. 在节点中通过变量名引用黑板变量
|
||||
|
||||
支持的变量类型:
|
||||
- String:字符串
|
||||
- Number:数字
|
||||
- Boolean:布尔值
|
||||
- Vector2:二维向量
|
||||
- Vector3:三维向量
|
||||
- Object:对象引用
|
||||
- Array:数组
|
||||
|
||||
## 导出运行时资产
|
||||
|
||||
### 导出步骤
|
||||
|
||||
1. 点击工具栏的"导出"按钮
|
||||
2. 选择导出模式:
|
||||
- 当前文件:仅导出当前打开的行为树
|
||||
- 工作区导出:导出项目中所有行为树
|
||||
3. 选择资产输出路径
|
||||
4. 选择TypeScript类型定义输出路径
|
||||
5. 为每个文件选择导出格式:
|
||||
- 二进制:.btree.bin(默认,文件更小,加载更快)
|
||||
- JSON:.btree.json(可读性好,便于调试)
|
||||
6. 点击"导出"按钮
|
||||
|
||||
### 加载运行时资产
|
||||
|
||||
编辑器导出的文件是编辑器格式,包含UI布局信息。当前版本中,从编辑器导出的资产可以使用Builder API在代码中重新构建,或者等待资产加载系统的完善。
|
||||
|
||||
推荐使用Builder API创建行为树:
|
||||
|
||||
```typescript
|
||||
import { BehaviorTreeBuilder, BehaviorTreeStarter } from '@esengine/behavior-tree';
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
|
||||
// 使用Builder创建行为树
|
||||
const tree = BehaviorTreeBuilder.create('EnemyAI')
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.defineBlackboardVariable('target', null)
|
||||
.selector('MainBehavior')
|
||||
.sequence('AttackBranch')
|
||||
.blackboardCompare('health', 50, 'greater')
|
||||
.log('攻击玩家', 'Attack')
|
||||
.end()
|
||||
.log('逃离战斗', 'Flee')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
// 启动行为树
|
||||
const entity = scene.createEntity('Enemy');
|
||||
BehaviorTreeStarter.start(entity, tree);
|
||||
```
|
||||
|
||||
## 支持的操作
|
||||
|
||||
- `Delete` / `Backspace`:删除选中的节点或连线
|
||||
- `Ctrl` + 点击:多选节点
|
||||
- 框选:拖拽空白区域进行框选
|
||||
- 拖拽画布:按住鼠标中键或空格键拖拽
|
||||
|
||||

|
||||
### 示例:行为树结构
|
||||
|
||||
```
|
||||
Root: Selector
|

|
||||
│ └── ExecuteAttack (Action)
|
||||
├── Patrol Sequence
|
||||
│ ├── MoveToNextPatrolPoint (Action)
|
||||
│ └── Wait 2s
|
||||
└── Idle (Action)
|
||||
```
|
||||
|
||||
## 在游戏中使用
|
||||
|
||||
### 使用Builder API创建
|
||||
|
||||
推荐使用Builder API在代码中创建行为树:
|
||||
|
||||
```typescript
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
import {
|
||||
BehaviorTreePlugin,
|
||||
BehaviorTreeBuilder,
|
||||
BehaviorTreeStarter,
|
||||
BehaviorTreeRuntimeComponent
|
||||
} from '@esengine/behavior-tree';
|
||||
|
||||
// 初始化
|
||||
Core.create();
|
||||
const plugin = new BehaviorTreePlugin();
|
||||
await Core.installPlugin(plugin);
|
||||
|
||||
const scene = new Scene();
|
||||
plugin.setupScene(scene);
|
||||
Core.setScene(scene);
|
||||
|
||||
// 使用Builder创建行为树
|
||||
const tree = BehaviorTreeBuilder.create('EnemyAI')
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.defineBlackboardVariable('target', null)
|
||||
.defineBlackboardVariable('moveSpeed', 5.0)
|
||||
.selector('MainBehavior')
|
||||
.sequence('AttackBranch')
|
||||
.blackboardExists('target')
|
||||
.blackboardCompare('health', 30, 'greater')
|
||||
.log('攻击目标', 'Attack')
|
||||
.end()
|
||||
.log('巡逻', 'Patrol')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
// 创建实体并启动行为树
|
||||
const entity = scene.createEntity('Enemy');
|
||||
BehaviorTreeStarter.start(entity, tree);
|
||||
|
||||
// 访问和修改黑板
|
||||
const runtime = entity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
runtime?.setBlackboardValue('target', someTarget);
|
||||
|
||||
// 游戏循环
|
||||
setInterval(() => {
|
||||
Core.update(0.016); // 60 FPS
|
||||
}, 16);
|
||||
```
|
||||
|
||||
## 实现自定义执行器
|
||||
|
||||
要扩展行为树的功能,需要创建自定义执行器(详见[自定义节点执行器](./custom-actions.md)):
|
||||
|
||||
```typescript
|
||||
import {
|
||||
INodeExecutor,
|
||||
NodeExecutionContext,
|
||||
BindingHelper,
|
||||
NodeExecutorMetadata
|
||||
} from '@esengine/behavior-tree';
|
||||
import { TaskStatus, NodeType } from '@esengine/behavior-tree';
|
||||
|
||||
@NodeExecutorMetadata({
|
||||
implementationType: 'AttackAction',
|
||||
nodeType: NodeType.Action,
|
||||
displayName: '攻击目标',
|
||||
description: '对目标造成伤害',
|
||||
category: '战斗',
|
||||
configSchema: {
|
||||
damage: {
|
||||
type: 'number',
|
||||
default: 10,
|
||||
supportBinding: true
|
||||
}
|
||||
}
|
||||
})
|
||||
export class AttackAction implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const damage = BindingHelper.getValue<number>(context, 'damage', 10);
|
||||
const target = context.runtime.getBlackboardValue('target');
|
||||
|
||||
if (!target) {
|
||||
return TaskStatus.Failure;
|
||||
}
|
||||
|
||||
// 执行攻击逻辑
|
||||
performAttack(context.entity, target, damage);
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
|
||||
reset(context: NodeExecutionContext): void {
|
||||
// 清理状态
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 调试技巧
|
||||
|
||||
### 1. 使用日志节点
|
||||
|
||||
在行为树中添加Log节点输出调试信息:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('DebugAI')
|
||||
.log('开始战斗序列', 'StartCombat')
|
||||
.sequence('Combat')
|
||||
.blackboardCompare('health', 0, 'greater')
|
||||
.log('执行攻击', 'Attack')
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 2. 监控黑板状态
|
||||
|
||||
```typescript
|
||||
const runtime = entity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
console.log('黑板变量:', runtime?.getAllBlackboardVariables());
|
||||
console.log('活动节点:', Array.from(runtime?.activeNodeIds || []));
|
||||
```
|
||||
|
||||
### 3. 在自定义执行器中调试
|
||||
|
||||
```typescript
|
||||
export class DebugAction implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const { nodeData, runtime, state } = context;
|
||||
|
||||
console.group(`[${nodeData.name}]`);
|
||||
console.log('配置:', nodeData.config);
|
||||
console.log('状态:', state);
|
||||
console.log('黑板:', runtime.getAllBlackboardVariables());
|
||||
console.groupEnd();
|
||||
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 完整示例
|
||||
|
||||
```typescript
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
import {
|
||||
BehaviorTreePlugin,
|
||||
BehaviorTreeBuilder,
|
||||
BehaviorTreeStarter,
|
||||
BehaviorTreeRuntimeComponent
|
||||
} from '@esengine/behavior-tree';
|
||||
|
||||
// 初始化
|
||||
Core.create();
|
||||
const plugin = new BehaviorTreePlugin();
|
||||
await Core.installPlugin(plugin);
|
||||
|
||||
const scene = new Scene();
|
||||
plugin.setupScene(scene);
|
||||
Core.setScene(scene);
|
||||
|
||||
// 使用Builder API构建行为树
|
||||
const tree = BehaviorTreeBuilder.create('EnemyAI')
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.defineBlackboardVariable('hasTarget', false)
|
||||
.selector('Root')
|
||||
.sequence('Combat')
|
||||
.blackboardCompare('hasTarget', true, 'equals')
|
||||
.log('攻击玩家', 'Attack')
|
||||
.end()
|
||||
.log('空闲', 'Idle')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
// 创建实体并启动
|
||||
const entity = scene.createEntity('Enemy');
|
||||
BehaviorTreeStarter.start(entity, tree);
|
||||
|

// 模拟发现目标
|
||||
setTimeout(() => {
|
||||
const runtime = entity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
runtime?.setBlackboardValue('hasTarget', true);
|
||||
}, 2000);
|
||||
|
||||
// 游戏循环
|
||||
setInterval(() => {
|
||||
Core.update(0.016);
|
||||
}, 16);

# 快速开始
|
||||
|
||||
本教程将引导你在5分钟内创建第一个行为树。
|
||||
|
||||
## 安装
|
||||
|
||||
```bash
|
||||
npm install @esengine/behavior-tree
|
||||
```
|
||||
|
||||
## 第一个行为树
|
||||
|
||||
让我们创建一个简单的AI行为树,实现"巡逻-发现敌人-攻击"的逻辑。
|
||||
|
||||
### 步骤1: 导入依赖
|
||||
|
||||
```typescript
|
||||
import { Core, Scene, Entity } from '@esengine/ecs-framework';
|
||||
import {
|
||||
BehaviorTreeBuilder,
|
||||
BehaviorTreeStarter,
|
||||
BehaviorTreePlugin
|
||||
} from '@esengine/behavior-tree';
|
||||
```
|
||||
|
||||
### 步骤2: 初始化Core并安装插件
|
||||
|
||||
```typescript
|
||||
Core.create();
|
||||
const plugin = new BehaviorTreePlugin();
|
||||
await Core.installPlugin(plugin);
|
||||
```
|
||||
|
||||
### 步骤3: 创建场景并设置行为树系统
|
||||
|
||||
```typescript
|
||||
const scene = new Scene();
|
||||
plugin.setupScene(scene);
|
||||
Core.setScene(scene);
|
||||
```
|
||||
|
||||
### 步骤4: 构建行为树数据
|
||||
|
||||
```typescript
|
||||
const guardAITree = BehaviorTreeBuilder.create('GuardAI')
|
||||
// 定义黑板变量
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.defineBlackboardVariable('hasEnemy', false)
|
||||
.defineBlackboardVariable('patrolPoint', 0)
|
||||
|
||||
// 根选择器
|
||||
.selector('RootSelector')
|
||||
// 分支1: 如果发现敌人且生命值高,则攻击
|
||||
.selector('CombatBranch')
|
||||
.blackboardExists('hasEnemy', 'CheckEnemy')
|
||||
.blackboardCompare('health', 30, 'greater', 'CheckHealth')
|
||||
.log('守卫正在攻击敌人', 'Attack')
|
||||
.end()
|
||||
|
||||
// 分支2: 如果生命值低,则逃跑
|
||||
.selector('FleeBranch')
|
||||
.blackboardCompare('health', 30, 'lessOrEqual', 'CheckLowHealth')
|
||||
.log('守卫生命值过低,正在逃跑', 'Flee')
|
||||
.end()
|
||||
|
||||
// 分支3: 默认巡逻
|
||||
.selector('PatrolBranch')
|
||||
.modifyBlackboardValue('patrolPoint', 'add', 1, 'IncrementPatrol')
|
||||
.log('守卫正在巡逻', 'Patrol')
|
||||
.wait(2.0, 'WaitAtPoint')
|
||||
.end()
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 步骤5: 创建实体并启动行为树
|
||||
|
||||
```typescript
|
||||
// 创建守卫实体
|
||||
const guardEntity = scene.createEntity('Guard');
|
||||
|
||||
// 启动行为树
|
||||
BehaviorTreeStarter.start(guardEntity, guardAITree);
|
||||
```
|
||||
|
||||
### 步骤6: 运行游戏循环
|
||||
|
||||
```typescript
|
||||
// 模拟游戏循环
|
||||
setInterval(() => {
|
||||
Core.update(0.1); // 传入deltaTime(秒)
|
||||
}, 100); // 每100ms更新一次
|
||||
```
|
||||
|
||||
### 步骤7: 模拟游戏事件
|
||||
|
||||
```typescript
|
||||
// 5秒后模拟发现敌人
|
||||
setTimeout(() => {
|
||||
const runtime = guardEntity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
runtime?.setBlackboardValue('hasEnemy', true);
|
||||
console.log('发现敌人!');
|
||||
}, 5000);
|
||||
|
||||
// 10秒后模拟受伤
|
||||
setTimeout(() => {
|
||||
const runtime = guardEntity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
runtime?.setBlackboardValue('health', 20);
|
||||
console.log('守卫受伤!');
|
||||
}, 10000);
|
||||
```
|
||||
|
||||
## 完整代码
|
||||
|
||||
```typescript
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
import {
|
||||
BehaviorTreeBuilder,
|
||||
BehaviorTreeStarter,
|
||||
BehaviorTreePlugin,
|
||||
BehaviorTreeRuntimeComponent
|
||||
} from '@esengine/behavior-tree';
|
||||
|
||||
async function main() {
|
||||
// 1. 创建核心并安装插件
|
||||
Core.create();
|
||||
const plugin = new BehaviorTreePlugin();
|
||||
await Core.installPlugin(plugin);
|
||||
|
||||
// 2. 创建场景
|
||||
const scene = new Scene();
|
||||
plugin.setupScene(scene);
|
||||
Core.setScene(scene);
|
||||
|
||||
// 3. 构建行为树数据
|
||||
const guardAITree = BehaviorTreeBuilder.create('GuardAI')
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.defineBlackboardVariable('hasEnemy', false)
|
||||
.defineBlackboardVariable('patrolPoint', 0)
|
||||
.selector('RootSelector')
|
||||
.selector('CombatBranch')
|
||||
.blackboardExists('hasEnemy')
|
||||
.blackboardCompare('health', 30, 'greater')
|
||||
.log('守卫正在攻击敌人')
|
||||
.end()
|
||||
.selector('FleeBranch')
|
||||
.blackboardCompare('health', 30, 'lessOrEqual')
|
||||
.log('守卫生命值过低,正在逃跑')
|
||||
.end()
|
||||
.selector('PatrolBranch')
|
||||
.modifyBlackboardValue('patrolPoint', 'add', 1)
|
||||
.log('守卫正在巡逻')
|
||||
.wait(2.0)
|
||||
.end()
|
||||
.end()
|
||||
.build();
|
||||
|
||||
// 4. 创建守卫实体并启动行为树
|
||||
const guardEntity = scene.createEntity('Guard');
|
||||
BehaviorTreeStarter.start(guardEntity, guardAITree);
|
||||
|
||||
// 5. 运行游戏循环
|
||||
setInterval(() => {
|
||||
Core.update(0.1);
|
||||
}, 100);
|
||||
|
||||
// 6. 模拟游戏事件
|
||||
setTimeout(() => {
|
||||
const runtime = guardEntity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
runtime?.setBlackboardValue('hasEnemy', true);
|
||||
console.log('发现敌人!');
|
||||
}, 5000);
|
||||
|
||||
setTimeout(() => {
|
||||
const runtime = guardEntity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
runtime?.setBlackboardValue('health', 20);
|
||||
console.log('守卫受伤!');
|
||||
}, 10000);
|
||||
}
|
||||
|
||||
main();
|
||||
```
|
||||
|
||||
## 运行结果
|
||||
|
||||
运行程序后,你会看到类似的输出:
|
||||
|
||||
```
|
||||
守卫正在巡逻
|
||||
守卫正在巡逻
|
||||
守卫正在巡逻
|
||||
发现敌人!
|
||||
守卫正在攻击敌人
|
||||
守卫正在攻击敌人
|
||||
守卫受伤!
|
||||
守卫生命值过低,正在逃跑
|
||||
```
|
||||
|
||||
## 理解代码
|
||||
|
||||
### 黑板变量
|
||||
|
||||
```typescript
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.defineBlackboardVariable('hasEnemy', false)
|
||||
.defineBlackboardVariable('patrolPoint', 0)
|
||||
```
|
||||
|
||||
黑板用于在节点之间共享数据。这里定义了三个变量:
|
||||
- `health`: 守卫的生命值
|
||||
- `hasEnemy`: 是否发现敌人
|
||||
- `patrolPoint`: 当前巡逻点编号
|
||||
|
||||
### 选择器节点
|
||||
|
||||
```typescript
|
||||
.selector('RootSelector')
|
||||
// 分支1
|
||||
// 分支2
|
||||
// 分支3
|
||||
.end()
|
||||
```
|
||||
|
||||
选择器按顺序尝试执行子节点,直到某个子节点返回成功。类似于编程中的 `if-else if-else`。
|
||||
|
||||
### 条件节点
|
||||
|
||||
```typescript
|
||||
.blackboardExists('hasEnemy') // 检查变量是否存在
|
||||
.blackboardCompare('health', 30, 'greater') // 比较变量值
|
||||
```
|
||||
|
||||
条件节点用于检查黑板变量的值。
|
||||
|
||||
### 动作节点
|
||||
|
||||
```typescript
|
||||
.log('守卫正在攻击敌人') // 输出日志
|
||||
.wait(2.0) // 等待2秒
|
||||
.modifyBlackboardValue('patrolPoint', 'add', 1) // 修改黑板值
|
||||
```
|
||||
|
||||
动作节点执行具体的操作。
|
||||
|
||||
### Runtime组件
|
||||
|
||||
```typescript
|
||||
const runtime = guardEntity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
runtime?.setBlackboardValue('hasEnemy', true);
|
||||
runtime?.getBlackboardValue('health');
|
||||
```
|
||||
|
||||
通过`BehaviorTreeRuntimeComponent`访问和修改黑板变量。
|
||||
|
||||
## 常见任务状态
|
||||
|
||||
行为树的每个节点返回以下状态之一:
|
||||
|
||||
- **Success**: 任务成功完成
|
||||
- **Failure**: 任务执行失败
|
||||
- **Running**: 任务正在执行,需要在后续帧继续
|
||||
- **Invalid**: 无效状态(未初始化或已重置)
|
||||
|
||||
## 内置节点
|
||||
|
||||
### 复合节点
|
||||
|
||||
- `sequence()` - 序列节点,按顺序执行所有子节点
|
||||
- `selector()` - 选择器节点,按顺序尝试子节点直到成功
|
||||
- `parallel()` - 并行节点,同时执行多个子节点
|
||||
- `parallelSelector()` - 并行选择器
|
||||
- `randomSequence()` - 随机序列
|
||||
- `randomSelector()` - 随机选择器
|
||||
|
||||
### 装饰器节点
|
||||
|
||||
- `inverter()` - 反转子节点结果
|
||||
- `repeater(count)` - 重复执行子节点
|
||||
- `alwaysSucceed()` - 总是返回成功
|
||||
- `alwaysFail()` - 总是返回失败
|
||||
- `untilSuccess()` - 重复直到成功
|
||||
- `untilFail()` - 重复直到失败
|
||||
- `conditional(key, value, operator)` - 条件装饰器
|
||||
- `cooldown(time)` - 冷却装饰器
|
||||
- `timeout(time)` - 超时装饰器
|
||||
|
||||
### 动作节点
|
||||
|
||||
- `wait(duration)` - 等待指定时间
|
||||
- `log(message)` - 输出日志
|
||||
- `setBlackboardValue(key, value)` - 设置黑板值
|
||||
- `modifyBlackboardValue(key, operation, value)` - 修改黑板值
|
||||
- `executeAction(actionName)` - 执行自定义动作
|
||||
|
||||
### 条件节点
|
||||
|
||||
- `blackboardExists(key)` - 检查变量是否存在
|
||||
- `blackboardCompare(key, value, operator)` - 比较黑板值
|
||||
- `randomProbability(probability)` - 随机概率
|
||||
- `executeCondition(conditionName)` - 执行自定义条件
|
||||
|
||||
## 控制行为树
|
||||
|
||||
### 启动
|
||||
|
||||
```typescript
|
||||
BehaviorTreeStarter.start(entity, treeData);
|
||||
```
|
||||
|
||||
### 停止
|
||||
|
||||
```typescript
|
||||
BehaviorTreeStarter.stop(entity);
|
||||
```
|
||||
|
||||
### 暂停和恢复
|
||||
|
||||
```typescript
|
||||
BehaviorTreeStarter.pause(entity);
|
||||
// ... 一段时间后
|
||||
BehaviorTreeStarter.resume(entity);
|
||||
```
|
||||
|
||||
### 重启
|
||||
|
||||
```typescript
|
||||
BehaviorTreeStarter.restart(entity);
|
||||
```
|
||||
|
||||
## 下一步
|
||||
|
||||
现在你已经创建了第一个行为树,接下来可以:
|
||||
|
||||
1. 学习[核心概念](./core-concepts.md)深入理解行为树原理
|
||||
2. 学习[资产管理](./asset-management.md)了解如何加载和复用行为树、使用子树
|
||||
3. 查看[自定义节点执行器](./custom-actions.md)学习如何创建自定义节点
|
||||
4. 根据你的场景查看集成教程:[Cocos Creator](./cocos-integration.md) 或 [Node.js](./nodejs-usage.md)
|
||||
5. 查看[高级用法](./advanced-usage.md)了解更多功能
|
||||
|
||||
## 常见问题
|
||||
|
||||
### 为什么行为树不执行?
|
||||
|
||||
确保:
|
||||
1. 已经安装了 `BehaviorTreePlugin`
|
||||
2. 调用了 `plugin.setupScene(scene)`
|
||||
3. 调用了 `BehaviorTreeStarter.start(entity, treeData)`
|
||||
4. 在游戏循环中调用了 `Core.update(deltaTime)`
|
||||
|
||||
### 如何访问黑板变量?
|
||||
|
||||
```typescript
|
||||
const runtime = entity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
|
||||
// 读取
|
||||
const health = runtime?.getBlackboardValue('health');
|
||||
|
||||
// 写入
|
||||
runtime?.setBlackboardValue('health', 50);
|
||||
|
||||
// 获取所有变量
|
||||
const allVars = runtime?.getAllBlackboardVariables();
|
||||
```
|
||||
|
||||
### 如何调试行为树?
|
||||
|
||||
使用日志节点:
|
||||
|
||||
```typescript
|
||||
.log('到达这个节点', 'DebugLog')
|
||||
```
|
||||
|
||||
或者在代码中监控黑板:
|
||||
|
||||
```typescript
|
||||
const runtime = entity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
console.log('黑板变量:', runtime?.getAllBlackboardVariables());
|
||||
console.log('活动节点:', Array.from(runtime?.activeNodeIds || []));
|
||||
```
|
||||
|
||||
### 如何使用自定义逻辑?
|
||||
|
||||
内置的`executeAction`和`executeCondition`节点只是占位符。要实现真正的自定义逻辑,你需要创建自定义执行器:
|
||||
|
||||
参见[自定义节点执行器](./custom-actions.md)学习如何创建。

# 行为树系统
|
||||
|
||||
行为树(Behavior Tree)是一种用于游戏AI和自动化控制的强大工具。本框架提供了基于Runtime执行器架构的行为树系统,具有高性能、类型安全、易于扩展的特点。
|
||||
|
||||
## 什么是行为树?
|
||||
|
||||
行为树是一种层次化的任务执行结构,由多个节点组成,每个节点负责特定的任务。行为树特别适合于:
|
||||
|
||||
- 游戏AI(敌人、NPC行为)
|
||||
- 状态机的替代方案
|
||||
- 复杂的决策逻辑
|
||||
- 可视化的行为设计
|
||||
|
||||
## 核心特性
|
||||
|
||||
### Runtime执行器架构

## 快速示例
|
||||
|
||||
### 使用Builder创建
|
||||
|
||||
```typescript
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
import {
|
||||
BehaviorTreeBuilder,
|
||||
BehaviorTreeStarter,
|
||||
BehaviorTreePlugin
|
||||
} from '@esengine/behavior-tree';
|
||||
|
||||
// 初始化
|
||||
Core.create();
|
||||
const plugin = new BehaviorTreePlugin();
|
||||
await Core.installPlugin(plugin);
|
||||
|
||||
const scene = new Scene();
|
||||
plugin.setupScene(scene);
|
||||
Core.setScene(scene);
|
||||
|
||||
// 创建行为树
|
||||
const enemyAI = BehaviorTreeBuilder.create('EnemyAI')
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.defineBlackboardVariable('target', null)
|
||||
.selector('MainBehavior')
|
||||
// 如果生命值高,则攻击
|
||||
.sequence('AttackBranch')
|
||||
.blackboardCompare('health', 50, 'greater')
|
||||
.log('攻击玩家', 'Attack')
|
||||
.end()
|
||||
// 否则逃跑
|
||||
.log('逃离战斗', 'Flee')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
// 启动AI
|
||||
const entity = scene.createEntity('Enemy');
|
||||
BehaviorTreeStarter.start(entity, enemyAI);
|
||||
```
|
||||
|
||||
### 使用编辑器创建
|
||||
|
||||
1. 打开行为树编辑器
|
||||
2. 创建新的行为树资产
|
||||
3. 拖拽节点到画布
|
||||
4. 配置节点属性和连接
|
||||
5. 保存并在代码中使用
|
||||
|
||||
## 架构说明
|
||||
|
||||
### Runtime执行器架构
|
||||
|
||||
本框架采用Runtime执行器架构,将节点定义和执行逻辑分离:
|
||||
|
||||
**核心组件:**
|
||||
- `BehaviorTreeData`: 纯数据结构,描述行为树
|
||||
- `BehaviorTreeRuntimeComponent`: 运行时组件,管理状态和黑板
|
||||
- `BehaviorTreeExecutionSystem`: 执行系统,驱动行为树运行
|
||||
- `INodeExecutor`: 节点执行器接口
|
||||
- `NodeExecutionContext`: 执行上下文
|
||||
|
||||
**优势:**
|
||||
- 数据与逻辑分离,易于序列化
|
||||
- 执行器无状态,可复用
|
||||
- 类型安全,编译时检查
|
||||
- 高性能执行
|
||||
|
||||
### 自定义执行器
|
||||
|
||||
创建自定义节点非常简单:
|
||||
|
||||
```typescript
|
||||
import {
|
||||
INodeExecutor,
|
||||
NodeExecutionContext,
|
||||
BindingHelper,
|
||||
NodeExecutorMetadata
|
||||
} from '@esengine/behavior-tree';
|
||||
import { TaskStatus, NodeType } from '@esengine/behavior-tree';
|
||||
|
||||
@NodeExecutorMetadata({
|
||||
implementationType: 'AttackAction',
|
||||
nodeType: NodeType.Action,
|
||||
displayName: '攻击',
|
||||
description: '攻击目标',
|
||||
category: '战斗',
|
||||
configSchema: {
|
||||
damage: {
|
||||
type: 'number',
|
||||
default: 10,
|
||||
supportBinding: true
|
||||
}
|
||||
}
|
||||
})
|
||||
export class AttackAction implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const damage = BindingHelper.getValue<number>(context, 'damage', 10);
|
||||
const target = context.runtime.getBlackboardValue('target');
|
||||
|
||||
if (!target) {
|
||||
return TaskStatus.Failure;
|
||||
}
|
||||
|
||||
console.log(`造成 ${damage} 点伤害`);
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
详细说明请参见[自定义节点执行器](./custom-actions.md)。
|
||||
|
||||

|
||||
```
|
||||
|
||||
|
||||
## 初始化
|
||||
|
||||
### 在Main.ts中初始化
|
||||
|
||||
```typescript
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
import { BehaviorTreePlugin } from '@esengine/behavior-tree';
|
||||
|
||||
export class Main {
|
||||
constructor() {
|
||||
Laya.init(1280, 720).then(() => {
|
||||
this.initECS();
|
||||
this.startGame();
|
||||
});
|
||||
}
|
||||
|
||||
private async initECS() {
|
||||
// 初始化 ECS
|
||||
Core.create();
|
||||
|
||||
// 安装行为树插件
|
||||
const btPlugin = new BehaviorTreePlugin();
|
||||
await Core.installPlugin(btPlugin);
|
||||
|
||||
// 创建并设置场景
|
||||
const scene = new Scene();
|
||||
btPlugin.setupScene(scene);
|
||||
Core.setScene(scene);
|
||||
|
||||
// 启动更新循环
|
||||
Laya.timer.frameLoop(1, this, this.update);
|
||||
}
|
||||
|
||||
private update() {
|
||||
// Core.update会自动更新场景
|
||||
Core.update(Laya.timer.delta / 1000);
|
||||
}
|
||||
|
||||
private startGame() {
|
||||
// 加载场景
|
||||
}
|
||||
}
|
||||
|
||||
new Main();
|
||||
```
|
||||
|
||||
|
||||
## 创建AI组件
|
||||
|
||||
```typescript
|
||||
import { Core, Entity } from '@esengine/ecs-framework';
|
||||
import {
|
||||
BehaviorTreeBuilder,
|
||||
BehaviorTreeStarter,
|
||||
BehaviorTreeRuntimeComponent
|
||||
} from '@esengine/behavior-tree';
|
||||
|
||||
export class EnemyAI extends Laya.Script {
|
||||
private aiEntity: Entity;
|
||||
|
||||
onEnable() {
|
||||
this.createBehaviorTree();
|
||||
}
|
||||
|
||||
private createBehaviorTree() {
|
||||
// 获取Core管理的场景
|
||||
const scene = Core.scene;
|
||||
if (!scene) {
|
||||
console.error('场景未初始化');
|
||||
return;
|
||||
}
|
||||
|
||||
const sprite = this.owner as Laya.Sprite;
|
||||
|
||||
// 使用Builder API创建行为树
|
||||
const tree = BehaviorTreeBuilder.create('EnemyAI')
|
||||
.defineBlackboardVariable('layaSprite', sprite)
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.defineBlackboardVariable('position', { x: sprite.x, y: sprite.y })
|
||||
.selector('MainBehavior')
|
||||
.sequence('Combat')
|
||||
.blackboardCompare('health', 30, 'greater')
|
||||
.log('攻击', 'Attack')
|
||||
.end()
|
||||
.log('巡逻', 'Patrol')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
// 创建AI实体并启动
|
||||
this.aiEntity = scene.createEntity(`AI_${sprite.name}`);
|
||||
BehaviorTreeStarter.start(this.aiEntity, tree);
|
||||
}
|
||||
|
||||
onDisable() {
|
||||
// 停止AI
|
||||
if (this.aiEntity) {
|
||||
BehaviorTreeStarter.stop(this.aiEntity);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 与Laya节点交互
|
||||
|
||||
要实现与Laya节点的交互,需要创建自定义执行器。下面展示一个完整示例。
|
||||
|
||||
## 完整示例
|
||||
|
||||
创建一个使用自定义执行器的敌人AI系统:
|
||||
|
||||
```typescript
|
||||
import {
|
||||
BehaviorTreeBuilder,
|
||||
BehaviorTreeStarter,
|
||||
INodeExecutor,
|
||||
NodeExecutionContext,
|
||||
NodeExecutorMetadata,
|
||||
BehaviorTreeRuntimeComponent
|
||||
} from '@esengine/behavior-tree';
|
||||
import { TaskStatus, NodeType } from '@esengine/behavior-tree';
|
||||
import { Core, Entity } from '@esengine/ecs-framework';
|
||||
|
||||
// 自定义移动执行器
|
||||
@NodeExecutorMetadata({
|
||||
implementationType: 'MoveToTarget',
|
||||
nodeType: NodeType.Action,
|
||||
displayName: '移动到目标',
|
||||
category: 'Laya',
|
||||
configSchema: {
|
||||
speed: {
|
||||
type: 'number',
|
||||
default: 50,
|
||||
supportBinding: true
|
||||
}
|
||||
}
|
||||
})
|
||||
export class MoveToTargetAction implements INodeExecutor {
|
||||
execute(context: NodeExecutionContext): TaskStatus {
|
||||
const sprite = context.runtime.getBlackboardValue('layaSprite');
|
||||
const targetPos = context.runtime.getBlackboardValue('targetPosition');
|
||||
const speed = context.nodeData.config.speed;
|
||||
|
||||
if (!sprite || !targetPos) {
|
||||
return TaskStatus.Failure;
|
||||
}
|
||||
|
||||
const dx = targetPos.x - sprite.x;
|
||||
const dy = targetPos.y - sprite.y;
|
||||
const distance = Math.sqrt(dx * dx + dy * dy);
|
||||
|
||||
if (distance < 10) {
|
||||
return TaskStatus.Success;
|
||||
}
|
||||
|
||||
sprite.x += (dx / distance) * speed * context.deltaTime;
|
||||
sprite.y += (dy / distance) * speed * context.deltaTime;
|
||||
|
||||
return TaskStatus.Running;
|
||||
}
|
||||
}
|
||||
|
||||
export class SimpleEnemyAI extends Laya.Script {
|
||||
public player: Laya.Sprite;
|
||||
|
||||
private aiEntity: Entity;
|
||||
|
||||
onEnable() {
|
||||
this.buildAI();
|
||||
}
|
||||
|
||||
private buildAI() {
|
||||
const scene = Core.scene;
|
||||
if (!scene) {
|
||||
console.error('场景未初始化');
|
||||
return;
|
||||
}
|
||||
|
||||
const sprite = this.owner as Laya.Sprite;
|
||||
|
||||
const tree = BehaviorTreeBuilder.create('EnemyAI')
|
||||
.defineBlackboardVariable('layaSprite', sprite)
|
||||
.defineBlackboardVariable('health', 100)
|
||||
.defineBlackboardVariable('player', this.player)
|
||||
.defineBlackboardVariable('targetPosition', { x: 0, y: 0 })
|
||||
.selector('MainBehavior')
|
||||
.sequence('Attack')
|
||||
.blackboardExists('player')
|
||||
.log('攻击玩家', 'DoAttack')
|
||||
.end()
|
||||
.log('巡逻', 'Patrol')
|
||||
.end()
|
||||
.build();
|
||||
|
||||
this.aiEntity = scene.createEntity(`AI_${sprite.name}`);
|
||||
BehaviorTreeStarter.start(this.aiEntity, tree);
|
||||
|
||||
// 可以在帧更新中修改黑板
|
||||
Laya.timer.frameLoop(1, this, () => {
|
||||
const runtime = this.aiEntity?.getComponent(BehaviorTreeRuntimeComponent);
|
||||
if (runtime && this.player) {
|
||||
runtime.setBlackboardValue('targetPosition', {
|
||||
x: this.player.x,
|
||||
y: this.player.y
|
||||
});
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
onDisable() {
|
||||
if (this.aiEntity) {
|
||||
BehaviorTreeStarter.stop(this.aiEntity);
|
||||
}
|
||||
Laya.timer.clearAll(this);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 性能优化
|
||||
|
||||
### 使用冷却装饰器
|
||||
|
||||
对于不需要每帧更新的AI,使用冷却装饰器:
|
||||
|
||||
```typescript
|
||||
const tree = BehaviorTreeBuilder.create('ThrottledAI')
|
||||
.cooldown(0.2, 'ThrottleRoot') // 每0.2秒执行一次
|
||||
.selector('MainBehavior')
|
||||
// AI逻辑...
|
||||
.end()
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 限制同时运行的AI数量
|
||||
|
||||
```typescript
|
||||
class AIManager {
|
||||
private activeAIs: Entity[] = [];
|
||||
private maxAIs: number = 20;
|
||||
|
||||
addAI(entity: Entity, tree: BehaviorTreeData) {
|
||||
if (this.activeAIs.length >= this.maxAIs) {
|
||||
const furthest = this.activeAIs.shift();
|
||||
if (furthest) {
|
||||
BehaviorTreeStarter.stop(furthest);
|
||||
}
|
||||
}
|
||||
|
||||
BehaviorTreeStarter.start(entity, tree);
|
||||
this.activeAIs.push(entity);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 常见问题
|
||||
|
||||
### 资源加载失败?
|
||||
|
||||
确保:
|
||||
1. 资源路径正确
|
||||
2. 资源已添加到项目中
|
||||
3. 使用 `Laya.loader.load()` 加载
|
||||
|
||||
### AI不执行?
|
||||
|
||||
检查:
|
||||
1. `onUpdate()` 是否被调用
|
||||
2. `Scene.update()` 是否执行
|
||||
3. 行为树是否已启动

TaskStatus,
|
||||
NodeType,
|

NodeExecutorMetadata
|
||||
} from '@esengine/behavior-tree';

||||
// 创建房间管理器

||||
const roomManager = new RoomManager();
|
||||
|
||||
// 模拟房间创建
|
||||
roomManager.createRoom('room_1');
|
||||
roomManager.createRoom('room_2');
|
||||
|
||||
// 服务器主循环(60 TPS)
|
||||
setInterval(() => {
|
||||
roomManager.update(1/60);
|
||||
}, 1000 / 60);
|
||||
|
||||
console.log('游戏服务器已启动');
|
||||
}
|
||||
|
||||
startGameServer();
|
||||
```
|
||||
|
||||
## 性能优化
|
||||
|
||||
### 1. 控制更新频率
|
||||
|
||||
```typescript
|
||||
// 不同类型的AI使用不同的更新频率
|
||||
class AIManager {
|
||||
private importantAIs: Entity[] = []; // Boss等重要AI,60 TPS
|
||||
private normalAIs: Entity[] = []; // 普通敌人,20 TPS
|
||||
private backgroundAIs: Entity[] = []; // 背景NPC,5 TPS
|
||||
|
||||
update() {
|
||||
// 重要AI每帧更新
|
||||
this.updateAIs(this.importantAIs, 1/60);
|
||||
|
||||
// 普通AI每3帧更新一次
|
||||
if (frameCount % 3 === 0) {
|
||||
this.updateAIs(this.normalAIs, 3/60);
|
||||
}
|
||||
|
||||
// 背景AI每12帧更新一次
|
||||
if (frameCount % 12 === 0) {
|
||||
this.updateAIs(this.backgroundAIs, 12/60);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 资源管理
|
||||
|
||||
```typescript
|
||||
// 使用资产管理器避免重复创建
|
||||
const assetManager = Core.services.resolve(BehaviorTreeAssetManager);
|
||||
|
||||
// 预加载所有AI
|
||||
const enemyAI = BehaviorTreeBuilder.create('EnemyAI').build();
|
||||
const bossAI = BehaviorTreeBuilder.create('BossAI').build();
|
||||
|
||||
assetManager.loadAsset(enemyAI);
|
||||
assetManager.loadAsset(bossAI);
|
||||
|
||||
// 创建1000个敌人,但只使用1份BehaviorTreeData
|
||||
for (let i = 0; i < 1000; i++) {
|
||||
const enemy = scene.createEntity(`Enemy${i}`);
|
||||
const ai = assetManager.getAsset('EnemyAI')!;
|
||||
BehaviorTreeStarter.start(enemy, ai);
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 使用对象池
|
||||
|
||||
```typescript
|
||||
class EntityPool {
|
||||
private pool: Entity[] = [];
|
||||
private active: Entity[] = [];
|
||||
|
||||
spawn(scene: Scene, treeId: string): Entity {
|
||||
let entity = this.pool.pop();
|
||||
|
||||
if (!entity) {
|
||||
entity = scene.createEntity();
|
||||
const tree = assetManager.getAsset(treeId)!;
|
||||
BehaviorTreeStarter.start(entity, tree);
|
||||
} else {
|
||||
BehaviorTreeStarter.restart(entity);
|
||||
}
|
||||
|
||||
this.active.push(entity);
|
||||
return entity;
|
||||
}
|
||||
|
||||
recycle(entity: Entity) {
|
||||
BehaviorTreeStarter.pause(entity);
|
||||
const index = this.active.indexOf(entity);
|
||||
if (index >= 0) {
|
||||
this.active.splice(index, 1);
|
||||
this.pool.push(entity);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 使用环境变量控制调试
|
||||
|
||||
```typescript
|
||||
const DEBUG = process.env.NODE_ENV === 'development';
|
||||
|
||||
const aiTree = BehaviorTreeBuilder.create('AI')
|
||||
.selector('Main')
|
||||
.when(DEBUG, builder =>
|
||||
builder.log('调试信息:开始AI逻辑')
|
||||
)
|
||||
// AI 逻辑...
|
||||
.end()
|
||||
.build();
|
||||
```
|
||||
|
||||
### 2. 错误处理
|
||||
|
||||
```typescript
|
||||
try {
|
||||
const tree = BehaviorTreeBuilder.create('AI')
|
||||
// ... 构建逻辑
|
||||
.build();
|
||||
|
||||
assetManager.loadAsset(tree);
|
||||
BehaviorTreeStarter.start(entity, tree);
|
||||
} catch (error) {
|
||||
console.error('启动AI失败:', error);
|
||||
// 使用默认AI或进行降级处理
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 监控和日志
|
||||
|
||||
```typescript
|
||||
// 定期输出AI状态
|
||||
setInterval(() => {
|
||||
const assetManager = Core.services.resolve(BehaviorTreeAssetManager);
|
||||
const count = assetManager.getAssetCount();
|
||||
const entities = scene.getEntitiesFor(Matcher.empty().all(BehaviorTreeRuntimeComponent));
|
||||
|
||||
console.log(`[AI监控] 行为树资产: ${count}, 活跃实体: ${entities.length}`);
|
||||
}, 10000);
|
||||
```
|
||||
|
||||
## 常见问题
|
||||
|
||||
### 如何与 Express/Koa 等框架集成?
|
||||
|
||||
```typescript
|
||||
import express from 'express';
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
|
||||
const app = express();
|
||||
const scene = new Scene();
|
||||
|
||||
// 在单独的循环中更新ECS
|
||||
setInterval(() => {
|
||||
Core.update(0.016);
|
||||
}, 16);
|
||||
|
||||
app.post('/npc/:id/interact', (req, res) => {
|
||||
const npcId = req.params.id;
|
||||
const npc = scene.findEntity(npcId);
|
||||
|
||||
if (npc) {
|
||||
const runtime = npc.getComponent(BehaviorTreeRuntimeComponent);
|
||||
runtime?.setBlackboardValue('playerRequest', req.body);
|
||||
|
||||
res.json({ success: true });
|
||||
} else {
|
||||
res.status(404).json({ error: 'NPC not found' });
|
||||
}
|
||||
});
|
||||
|
||||
app.listen(3000);
|
||||
```
|
||||
|
||||
### 如何持久化行为树状态?
|
||||
|
||||
```typescript
|
||||
// 保存状态
|
||||
function saveAIState(entity: Entity) {
|
||||
const runtime = entity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
if (runtime) {
|
||||
return {
|
||||
treeId: runtime.treeId,
|
||||
blackboard: runtime.getAllBlackboardVariables(),
|
||||
activeNodes: Array.from(runtime.activeNodeIds)
|
||||
};
|
||||
}
|
||||
}
|
||||
|
||||
// 恢复状态
|
||||
function loadAIState(entity: Entity, savedState: any) {
|
||||
const runtime = entity.getComponent(BehaviorTreeRuntimeComponent);
|
||||
if (runtime) {
|
||||
// 恢复黑板变量
|
||||
Object.entries(savedState.blackboard).forEach(([key, value]) => {
|
||||
runtime.setBlackboardValue(key, value);
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||

# 组件系统
|
||||
|
||||
在 ECS 架构中,组件(Component)是数据和行为的载体。组件定义了实体具有的属性和功能,是 ECS 架构的核心构建块。
|
||||
|
||||
## 基本概念
|
||||
|
||||
组件是继承自 `Component` 抽象基类的具体类,用于:
|
||||
- 存储实体的数据(如位置、速度、健康值等)
|
||||
- 定义与数据相关的行为方法
|
||||
- 提供生命周期回调钩子
|
||||
- 支持序列化和调试
|
||||
|
||||
## 创建组件
|
||||
|
||||
### 基础组件定义
|
||||
|
||||
```typescript
|
||||
import { Component, ECSComponent } from '@esengine/ecs-framework';
|
||||
|
||||
@ECSComponent('Position')
|
||||
class Position extends Component {
|
||||
x: number = 0;
|
||||
y: number = 0;
|
||||
|
||||
constructor(x: number = 0, y: number = 0) {
|
||||
super();
|
||||
this.x = x;
|
||||
this.y = y;
|
||||
}
|
||||
}
|
||||
|
||||
@ECSComponent('Health')
|
||||
class Health extends Component {
|
||||
current: number;
|
||||
max: number;
|
||||
|
||||
constructor(max: number = 100) {
|
||||
super();
|
||||
this.max = max;
|
||||
this.current = max;
|
||||
}
|
||||
|
||||
// 组件可以包含行为方法
|
||||
takeDamage(damage: number): void {
|
||||
this.current = Math.max(0, this.current - damage);
|
||||
}
|
||||
|
||||
heal(amount: number): void {
|
||||
this.current = Math.min(this.max, this.current + amount);
|
||||
}
|
||||
|
||||
isDead(): boolean {
|
||||
return this.current <= 0;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### @ECSComponent 装饰器
|
||||
|
||||
`@ECSComponent` 是组件类必须使用的装饰器,它为组件提供了类型标识和元数据管理。
|
||||
|
||||
#### 为什么必须使用
|
||||
|
||||
| 功能 | 说明 |
|
||||
|------|------|
|
||||
| **类型识别** | 提供稳定的类型名称,代码混淆后仍能正确识别 |
|
||||
| **序列化支持** | 序列化/反序列化时使用该名称作为类型标识 |
|
||||
| **组件注册** | 自动注册到 ComponentRegistry,分配唯一的位掩码 |
|
||||
| **调试支持** | 在调试工具和日志中显示可读的组件名称 |
|
||||
|
||||
#### 基本语法
|
||||
|
||||
```typescript
|
||||
@ECSComponent(typeName: string)
|
||||
```
|
||||
|
||||
- `typeName`: 组件的类型名称,建议使用与类名相同或相近的名称
|
||||
|
||||
#### 使用示例
|
||||
|
||||
```typescript
|
||||
// ✅ 正确的用法
|
||||
@ECSComponent('Velocity')
|
||||
class Velocity extends Component {
|
||||
dx: number = 0;
|
||||
dy: number = 0;
|
||||
}
|
||||
|
||||
// ✅ 推荐:类型名与类名保持一致
|
||||
@ECSComponent('PlayerController')
|
||||
class PlayerController extends Component {
|
||||
speed: number = 5;
|
||||
}
|
||||
|
||||
// ❌ 错误的用法 - 没有装饰器
|
||||
class BadComponent extends Component {
|
||||
// 这样定义的组件可能在生产环境出现问题:
|
||||
// 1. 代码压缩后类名变化,无法正确序列化
|
||||
// 2. 组件未注册到框架,查询和匹配可能失效
|
||||
}
|
||||
```
|
||||
|
||||
#### 与 @Serializable 配合使用
|
||||
|
||||
当组件需要支持序列化时,`@ECSComponent` 和 `@Serializable` 需要一起使用:
|
||||
|
||||
```typescript
|
||||
import { Component, ECSComponent, Serializable, Serialize } from '@esengine/ecs-framework';
|
||||
|
||||
@ECSComponent('Player')
|
||||
@Serializable({ version: 1 })
|
||||
class PlayerComponent extends Component {
|
||||
@Serialize()
|
||||
name: string = '';
|
||||
|
||||
@Serialize()
|
||||
level: number = 1;
|
||||
|
||||
// 不使用 @Serialize() 的字段不会被序列化
|
||||
private _cachedData: any = null;
|
||||
}
|
||||
```
|
||||
|
||||
> **注意**:`@ECSComponent` 的 `typeName` 和 `@Serializable` 的 `typeId` 可以不同。如果 `@Serializable` 没有指定 `typeId`,则默认使用 `@ECSComponent` 的 `typeName`。
|
||||
|
||||
#### 组件类型名的唯一性
|
||||
|
||||
每个组件的类型名应该是唯一的:
|
||||
|
||||
```typescript
|
||||
// ❌ 错误:两个组件使用相同的类型名
|
||||
@ECSComponent('Health')
|
||||
class HealthComponent extends Component { }
|
||||
|
||||
@ECSComponent('Health') // 冲突!
|
||||
class EnemyHealthComponent extends Component { }
|
||||
|
||||
// ✅ 正确:使用不同的类型名
|
||||
@ECSComponent('PlayerHealth')
|
||||
class PlayerHealthComponent extends Component { }
|
||||
|
||||
@ECSComponent('EnemyHealth')
|
||||
class EnemyHealthComponent extends Component { }
|
||||
```
|
||||
|
||||
## 组件生命周期
|
||||
|
||||
组件提供了生命周期钩子,可以重写来执行特定的逻辑:
|
||||
|
||||
```typescript
|
||||
@ECSComponent('ExampleComponent')
|
||||
class ExampleComponent extends Component {
|
||||
private resource: SomeResource | null = null;
|
||||
|
||||
/**
|
||||
* 组件被添加到实体时调用
|
||||
* 用于初始化资源、建立引用等
|
||||
*/
|
||||
onAddedToEntity(): void {
|
||||
console.log(`组件 ${this.constructor.name} 已添加,实体ID: ${this.entityId}`);
|
||||
this.resource = new SomeResource();
|
||||
}
|
||||
|
||||
/**
|
||||
* 组件从实体移除时调用
|
||||
* 用于清理资源、断开引用等
|
||||
*/
|
||||
onRemovedFromEntity(): void {
|
||||
console.log(`组件 ${this.constructor.name} 已移除`);
|
||||
if (this.resource) {
|
||||
this.resource.cleanup();
|
||||
this.resource = null;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 组件与实体的关系
|
||||
|
||||
组件存储了所属实体的ID (`entityId`),而不是直接引用实体对象。这是ECS数据导向设计的体现,避免了循环引用。
|
||||
|
||||
在实际使用中,**应该在 System 中处理实体和组件的交互**,而不是在组件内部:
|
||||
|
||||
```typescript
|
||||
@ECSComponent('Health')
|
||||
class Health extends Component {
|
||||
current: number;
|
||||
max: number;
|
||||
|
||||
constructor(max: number = 100) {
|
||||
super();
|
||||
this.max = max;
|
||||
this.current = max;
|
||||
}
|
||||
|
||||
isDead(): boolean {
|
||||
return this.current <= 0;
|
||||
}
|
||||
}
|
||||
|
||||
@ECSComponent('Damage')
|
||||
class Damage extends Component {
|
||||
value: number;
|
||||
|
||||
constructor(value: number) {
|
||||
super();
|
||||
this.value = value;
|
||||
}
|
||||
}
|
||||
|
||||
// 推荐:在 System 中处理逻辑
|
||||
class DamageSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(new Matcher().all(Health, Damage));
|
||||
}
|
||||
|
||||
process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const health = entity.getComponent(Health)!;
|
||||
const damage = entity.getComponent(Damage)!;
|
||||
|
||||
health.current -= damage.value;
|
||||
|
||||
if (health.isDead()) {
|
||||
entity.destroy();
|
||||
}
|
||||
|
||||
// 应用伤害后移除 Damage 组件
|
||||
entity.removeComponent(damage);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 组件属性
|
||||
|
||||
每个组件都有一些内置属性:
|
||||
|
||||
```typescript
|
||||
@ECSComponent('ExampleComponent')
|
||||
class ExampleComponent extends Component {
|
||||
someData: string = "example";
|
||||
|
||||
onAddedToEntity(): void {
|
||||
console.log(`组件ID: ${this.id}`); // 唯一的组件ID
|
||||
console.log(`所属实体ID: ${this.entityId}`); // 所属实体的ID
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
如果需要访问实体对象,应该在 System 中进行:
|
||||
|
||||
```typescript
|
||||
class ExampleSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(new Matcher().all(ExampleComponent));
|
||||
}
|
||||
|
||||
process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const comp = entity.getComponent(ExampleComponent)!;
|
||||
console.log(`实体名称: ${entity.name}`);
|
||||
console.log(`组件数据: ${comp.someData}`);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 复杂组件示例
|
||||
|
||||
### 状态机组件
|
||||
|
||||
```typescript
|
||||
enum EntityState {
|
||||
Idle,
|
||||
Moving,
|
||||
Attacking,
|
||||
Dead
|
||||
}
|
||||
|
||||
@ECSComponent('StateMachine')
|
||||
class StateMachine extends Component {
|
||||
private _currentState: EntityState = EntityState.Idle;
|
||||
private _previousState: EntityState = EntityState.Idle;
|
||||
private _stateTimer: number = 0;
|
||||
|
||||
get currentState(): EntityState {
|
||||
return this._currentState;
|
||||
}
|
||||
|
||||
get previousState(): EntityState {
|
||||
return this._previousState;
|
||||
}
|
||||
|
||||
get stateTimer(): number {
|
||||
return this._stateTimer;
|
||||
}
|
||||
|
||||
changeState(newState: EntityState): void {
|
||||
if (this._currentState !== newState) {
|
||||
this._previousState = this._currentState;
|
||||
this._currentState = newState;
|
||||
this._stateTimer = 0;
|
||||
}
|
||||
}
|
||||
|
||||
updateTimer(deltaTime: number): void {
|
||||
this._stateTimer += deltaTime;
|
||||
}
|
||||
|
||||
isInState(state: EntityState): boolean {
|
||||
return this._currentState === state;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 配置数据组件
|
||||
|
||||
```typescript
|
||||
interface WeaponData {
|
||||
damage: number;
|
||||
range: number;
|
||||
fireRate: number;
|
||||
ammo: number;
|
||||
}
|
||||
|
||||
@ECSComponent('WeaponConfig')
|
||||
class WeaponConfig extends Component {
|
||||
data: WeaponData;
|
||||
|
||||
constructor(weaponData: WeaponData) {
|
||||
super();
|
||||
this.data = { ...weaponData }; // 深拷贝避免共享引用
|
||||
}
|
||||
|
||||
// 提供便捷的访问方法
|
||||
getDamage(): number {
|
||||
return this.data.damage;
|
||||
}
|
||||
|
||||
canFire(): boolean {
|
||||
return this.data.ammo > 0;
|
||||
}
|
||||
|
||||
consumeAmmo(): boolean {
|
||||
if (this.data.ammo > 0) {
|
||||
this.data.ammo--;
|
||||
return true;
|
||||
}
|
||||
return false;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 保持组件简单
|
||||
|
||||
```typescript
|
||||
// 好的组件设计 - 单一职责
|
||||
@ECSComponent('Position')
|
||||
class Position extends Component {
|
||||
x: number = 0;
|
||||
y: number = 0;
|
||||
}
|
||||
|
||||
@ECSComponent('Velocity')
|
||||
class Velocity extends Component {
|
||||
dx: number = 0;
|
||||
dy: number = 0;
|
||||
}
|
||||
|
||||
// 避免的组件设计 - 职责过多
|
||||
@ECSComponent('GameObject')
|
||||
class GameObject extends Component {
|
||||
x: number;
|
||||
y: number;
|
||||
dx: number;
|
||||
dy: number;
|
||||
health: number;
|
||||
damage: number;
|
||||
sprite: string;
|
||||
// 太多不相关的属性
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 使用构造函数初始化
|
||||
|
||||
```typescript
|
||||
@ECSComponent('Transform')
|
||||
class Transform extends Component {
|
||||
x: number;
|
||||
y: number;
|
||||
rotation: number;
|
||||
scale: number;
|
||||
|
||||
constructor(x = 0, y = 0, rotation = 0, scale = 1) {
|
||||
super();
|
||||
this.x = x;
|
||||
this.y = y;
|
||||
this.rotation = rotation;
|
||||
this.scale = scale;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 明确的类型定义
|
||||
|
||||
```typescript
|
||||
interface InventoryItem {
|
||||
id: string;
|
||||
name: string;
|
||||
quantity: number;
|
||||
type: 'weapon' | 'consumable' | 'misc';
|
||||
}
|
||||
|
||||
@ECSComponent('Inventory')
|
||||
class Inventory extends Component {
|
||||
items: InventoryItem[] = [];
|
||||
maxSlots: number;
|
||||
|
||||
constructor(maxSlots: number = 20) {
|
||||
super();
|
||||
this.maxSlots = maxSlots;
|
||||
}
|
||||
|
||||
addItem(item: InventoryItem): boolean {
|
||||
if (this.items.length < this.maxSlots) {
|
||||
this.items.push(item);
|
||||
return true;
|
||||
}
|
||||
return false;
|
||||
}
|
||||
|
||||
removeItem(itemId: string): InventoryItem | null {
|
||||
const index = this.items.findIndex(item => item.id === itemId);
|
||||
if (index !== -1) {
|
||||
return this.items.splice(index, 1)[0];
|
||||
}
|
||||
return null;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 引用其他实体
|
||||
|
||||
当组件需要关联其他实体时(如父子关系、跟随目标等),**推荐方式是存储实体ID**,然后在 System 中查找:
|
||||
|
||||
```typescript
|
||||
@ECSComponent('Follower')
|
||||
class Follower extends Component {
|
||||
targetId: number;
|
||||
followDistance: number = 50;
|
||||
|
||||
constructor(targetId: number) {
|
||||
super();
|
||||
this.targetId = targetId;
|
||||
}
|
||||
}
|
||||
|
||||
// 在 System 中查找目标实体并处理逻辑
|
||||
class FollowerSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(new Matcher().all(Follower, Position));
|
||||
}
|
||||
|
||||
process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const follower = entity.getComponent(Follower)!;
|
||||
const position = entity.getComponent(Position)!;
|
||||
|
||||
// 通过场景查找目标实体
|
||||
const target = entity.scene?.findEntityById(follower.targetId);
|
||||
if (target) {
|
||||
const targetPos = target.getComponent(Position);
|
||||
if (targetPos) {
|
||||
// 跟随逻辑
|
||||
const dx = targetPos.x - position.x;
|
||||
const dy = targetPos.y - position.y;
|
||||
const distance = Math.sqrt(dx * dx + dy * dy);
|
||||
|
||||
if (distance > follower.followDistance) {
|
||||
// 移动靠近目标
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
这种方式的优势:
|
||||
- 组件保持简单,只存储基本数据类型
|
||||
- 符合数据导向设计
|
||||
- 在 System 中统一处理查找和逻辑
|
||||
- 易于理解和维护
|
||||
|
||||
**避免在组件中直接存储实体引用**:
|
||||
|
||||
```typescript
|
||||
// 错误示范:直接存储实体引用
|
||||
@ECSComponent('BadFollower')
|
||||
class BadFollower extends Component {
|
||||
target: Entity; // 实体销毁后仍持有引用,可能导致内存泄漏
|
||||
}
|
||||
```
|
||||
|
||||
## 高级特性
|
||||
|
||||
### EntityRef 装饰器 - 自动引用追踪
|
||||
|
||||
框架提供了 `@EntityRef` 装饰器用于**特殊场景**下安全地存储实体引用。这是一个高级特性,一般情况下推荐使用存储ID的方式。
|
||||
|
||||
#### 什么时候需要 EntityRef?
|
||||
|
||||
在以下场景中,`@EntityRef` 可以简化代码:
|
||||
|
||||
1. **父子关系**: 需要在组件中直接访问父实体或子实体
|
||||
2. **复杂关联**: 实体之间有多个引用关系
|
||||
3. **频繁访问**: 需要在多处访问引用的实体,使用ID查找会有性能开销
|
||||
|
||||
#### 核心特性
|
||||
|
||||
`@EntityRef` 装饰器通过 **ReferenceTracker** 自动追踪引用关系:
|
||||
|
||||
- 当被引用的实体销毁时,所有指向它的 `@EntityRef` 属性自动设为 `null`
|
||||
- 防止跨场景引用(会输出警告并拒绝设置)
|
||||
- 防止引用已销毁的实体(会输出警告并设为 `null`)
|
||||
- 使用 WeakRef 避免内存泄漏(自动GC支持)
|
||||
- 组件移除时自动清理引用注册
|
||||
|
||||
#### 基本用法
|
||||
|
||||
```typescript
|
||||
import { Component, ECSComponent, EntityRef, Entity } from '@esengine/ecs-framework';
|
||||
|
||||
@ECSComponent('Parent')
|
||||
class ParentComponent extends Component {
|
||||
@EntityRef()
|
||||
parent: Entity | null = null;
|
||||
}
|
||||
|
||||
// 使用示例
|
||||
const scene = new Scene();
|
||||
const parent = scene.createEntity('Parent');
|
||||
const child = scene.createEntity('Child');
|
||||
|
||||
const comp = child.addComponent(new ParentComponent());
|
||||
comp.parent = parent;
|
||||
|
||||
console.log(comp.parent); // Entity { name: 'Parent' }
|
||||
|
||||
// 当 parent 被销毁时,comp.parent 自动变为 null
|
||||
parent.destroy();
|
||||
console.log(comp.parent); // null
|
||||
```
|
||||
|
||||
#### 多个引用属性
|
||||
|
||||
一个组件可以有多个 `@EntityRef` 属性:
|
||||
|
||||
```typescript
|
||||
@ECSComponent('Combat')
|
||||
class CombatComponent extends Component {
|
||||
@EntityRef()
|
||||
target: Entity | null = null;
|
||||
|
||||
@EntityRef()
|
||||
ally: Entity | null = null;
|
||||
|
||||
@EntityRef()
|
||||
lastAttacker: Entity | null = null;
|
||||
}
|
||||
|
||||
// 使用示例
|
||||
const player = scene.createEntity('Player');
|
||||
const enemy = scene.createEntity('Enemy');
|
||||
const npc = scene.createEntity('NPC');
|
||||
|
||||
const combat = player.addComponent(new CombatComponent());
|
||||
combat.target = enemy;
|
||||
combat.ally = npc;
|
||||
|
||||
// enemy 销毁后,只有 target 变为 null,ally 仍然有效
|
||||
enemy.destroy();
|
||||
console.log(combat.target); // null
|
||||
console.log(combat.ally); // Entity { name: 'NPC' }
|
||||
```
|
||||
|
||||
#### 安全检查
|
||||
|
||||
`@EntityRef` 提供了多重安全检查:
|
||||
|
||||
```typescript
|
||||
const scene1 = new Scene();
|
||||
const scene2 = new Scene();
|
||||
|
||||
const entity1 = scene1.createEntity('Entity1');
|
||||
const entity2 = scene2.createEntity('Entity2');
|
||||
|
||||
const comp = entity1.addComponent(new ParentComponent());
|
||||
|
||||
// 跨场景引用会失败
|
||||
comp.parent = entity2; // 输出错误日志,comp.parent 为 null
|
||||
console.log(comp.parent); // null
|
||||
|
||||
// 引用已销毁的实体会失败
|
||||
const entity3 = scene1.createEntity('Entity3');
|
||||
entity3.destroy();
|
||||
comp.parent = entity3; // 输出警告日志,comp.parent 为 null
|
||||
console.log(comp.parent); // null
|
||||
```
|
||||
|
||||
#### 实现原理
|
||||
|
||||
`@EntityRef` 使用以下机制实现自动引用追踪:
|
||||
|
||||
1. **ReferenceTracker**: Scene 持有一个引用追踪器,记录所有实体引用关系
|
||||
2. **WeakRef**: 使用弱引用存储组件,避免循环引用导致内存泄漏
|
||||
3. **属性拦截**: 通过 `Object.defineProperty` 拦截 getter/setter
|
||||
4. **自动清理**: 实体销毁时,ReferenceTracker 遍历所有引用并设为 null
|
||||
|
||||
```typescript
|
||||
// 简化的实现原理
|
||||
class ReferenceTracker {
|
||||
// entityId -> 引用该实体的所有组件记录
|
||||
private _references: Map<number, Set<{ component: WeakRef<Component>, propertyKey: string }>>;
|
||||
|
||||
// 实体销毁时调用
|
||||
clearReferencesTo(entityId: number): void {
|
||||
const records = this._references.get(entityId);
|
||||
if (records) {
|
||||
for (const record of records) {
|
||||
const component = record.component.deref();
|
||||
if (component) {
|
||||
// 将组件的引用属性设为 null
|
||||
(component as any)[record.propertyKey] = null;
|
||||
}
|
||||
}
|
||||
this._references.delete(entityId);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 性能考虑
|
||||
|
||||
`@EntityRef` 会带来一些性能开销:
|
||||
|
||||
- **写入开销**: 每次设置引用时需要更新 ReferenceTracker
|
||||
- **内存开销**: ReferenceTracker 需要维护引用映射表
|
||||
- **销毁开销**: 实体销毁时需要遍历所有引用并清理
|
||||
|
||||
对于大多数场景,这些开销是可以接受的。但如果有**大量实体和频繁的引用变更**,存储ID可能更高效。
|
||||
|
||||
#### 最佳实践
|
||||
|
||||
```typescript
|
||||
// 推荐:适合使用 @EntityRef 的场景 - 父子关系
|
||||
@ECSComponent('Transform')
|
||||
class Transform extends Component {
|
||||
@EntityRef()
|
||||
parent: Entity | null = null;
|
||||
|
||||
position: { x: number, y: number } = { x: 0, y: 0 };
|
||||
|
||||
// 可以直接访问父实体的组件
|
||||
getWorldPosition(): { x: number, y: number } {
|
||||
if (!this.parent) {
|
||||
return { ...this.position };
|
||||
}
|
||||
|
||||
const parentTransform = this.parent.getComponent(Transform);
|
||||
if (parentTransform) {
|
||||
const parentPos = parentTransform.getWorldPosition();
|
||||
return {
|
||||
x: parentPos.x + this.position.x,
|
||||
y: parentPos.y + this.position.y
|
||||
};
|
||||
}
|
||||
|
||||
return { ...this.position };
|
||||
}
|
||||
}
|
||||
|
||||
// 不推荐:不适合使用 @EntityRef 的场景 - 大量动态目标
|
||||
@ECSComponent('AITarget')
|
||||
class AITarget extends Component {
|
||||
@EntityRef()
|
||||
target: Entity | null = null; // 如果目标频繁变化,用ID更好
|
||||
|
||||
updateCooldown: number = 0;
|
||||
}
|
||||
|
||||
// 推荐:这种场景用ID更好
|
||||
@ECSComponent('AITarget')
|
||||
class AITargetBetter extends Component {
|
||||
targetId: number | null = null; // 存储ID
|
||||
updateCooldown: number = 0;
|
||||
}
|
||||
```
|
||||
|
||||
#### 调试支持
|
||||
|
||||
ReferenceTracker 提供了调试接口:
|
||||
|
||||
```typescript
|
||||
// 查看某个实体被哪些组件引用
|
||||
const references = scene.referenceTracker.getReferencesTo(entity.id);
|
||||
console.log(`实体 ${entity.name} 被 ${references.length} 个组件引用`);
|
||||
|
||||
// 获取完整的调试信息
|
||||
const debugInfo = scene.referenceTracker.getDebugInfo();
|
||||
console.log(debugInfo);
|
||||
```
|
||||
|
||||
#### 总结
|
||||
|
||||
- **推荐做法**: 大部分情况使用存储ID + System查找的方式
|
||||
- **EntityRef 适用场景**: 父子关系、复杂关联、组件内需要直接访问引用实体的场景
|
||||
- **核心优势**: 自动清理、防止悬空引用、代码更简洁
|
||||
- **注意事项**: 有性能开销,不适合大量动态引用的场景
|
||||
|
||||
组件是 ECS 架构的数据载体,正确设计组件能让你的游戏代码更模块化、可维护和高性能。

# 实体查询系统
|
||||
|
||||
实体查询是 ECS 架构的核心功能之一。本指南将介绍如何使用 Matcher 和 QuerySystem 来查询和筛选实体。
|
||||
|
||||
## 核心概念
|
||||
|
||||
### Matcher - 查询条件描述符
|
||||
|
||||
Matcher 是一个链式 API,用于描述实体查询条件。它本身不执行查询,而是作为条件传递给 EntitySystem 或 QuerySystem。
|
||||
|
||||
### QuerySystem - 查询执行引擎
|
||||
|
||||
QuerySystem 负责实际执行查询,内部使用响应式查询机制自动优化性能。
|
||||
|
||||
## 在 EntitySystem 中使用 Matcher
|
||||
|
||||
这是最常见的使用方式。EntitySystem 通过 Matcher 自动筛选和处理符合条件的实体。
|
||||
|
||||
### 基础用法
|
||||
|
||||
```typescript
|
||||
import { EntitySystem, Matcher, Entity, Component } from '@esengine/ecs-framework';
|
||||
|
||||
class PositionComponent extends Component {
|
||||
public x: number = 0;
|
||||
public y: number = 0;
|
||||
}
|
||||
|
||||
class VelocityComponent extends Component {
|
||||
public vx: number = 0;
|
||||
public vy: number = 0;
|
||||
}
|
||||
|
||||
class MovementSystem extends EntitySystem {
|
||||
constructor() {
|
||||
// 方式1: 使用 Matcher.empty().all()
|
||||
super(Matcher.empty().all(PositionComponent, VelocityComponent));
|
||||
|
||||
// 方式2: 直接使用 Matcher.all() (等价)
|
||||
// super(Matcher.all(PositionComponent, VelocityComponent));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const pos = entity.getComponent(PositionComponent)!;
|
||||
const vel = entity.getComponent(VelocityComponent)!;
|
||||
|
||||
pos.x += vel.vx;
|
||||
pos.y += vel.vy;
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// 添加到场景
|
||||
scene.addEntityProcessor(new MovementSystem());
|
||||
```
|
||||
|
||||
### Matcher 链式 API
|
||||
|
||||
#### all() - 必须包含所有组件
|
||||
|
||||
```typescript
|
||||
class HealthSystem extends EntitySystem {
|
||||
constructor() {
|
||||
// 实体必须同时拥有 Health 和 Position 组件
|
||||
super(Matcher.empty().all(HealthComponent, PositionComponent));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 只处理同时拥有两个组件的实体
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### any() - 至少包含一个组件
|
||||
|
||||
```typescript
|
||||
class DamageableSystem extends EntitySystem {
|
||||
constructor() {
|
||||
// 实体至少拥有 Health 或 Shield 其中之一
|
||||
super(Matcher.any(HealthComponent, ShieldComponent));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 处理拥有生命值或护盾的实体
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### none() - 不能包含指定组件
|
||||
|
||||
```typescript
|
||||
class AliveEntitySystem extends EntitySystem {
|
||||
constructor() {
|
||||
// 实体不能拥有 DeadTag 组件
|
||||
super(Matcher.all(HealthComponent).none(DeadTag));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 只处理活着的实体
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 组合条件
|
||||
|
||||
```typescript
|
||||
class CombatSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(
|
||||
Matcher.empty()
|
||||
.all(PositionComponent, HealthComponent) // 必须有位置和生命
|
||||
.any(WeaponComponent, MagicComponent) // 至少有武器或魔法
|
||||
.none(DeadTag, FrozenTag) // 不能是死亡或冰冻状态
|
||||
);
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 处理可以战斗的活着的实体
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### nothing() - 不匹配任何实体
|
||||
|
||||
用于创建只需要生命周期方法(`onBegin`、`onEnd`)但不需要处理实体的系统。
|
||||
|
||||
```typescript
|
||||
class FrameTimerSystem extends EntitySystem {
|
||||
constructor() {
|
||||
// 不匹配任何实体
|
||||
super(Matcher.nothing());
|
||||
}
|
||||
|
||||
protected onBegin(): void {
|
||||
// 每帧开始时执行
|
||||
Performance.markFrameStart();
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 永远不会被调用,因为没有匹配的实体
|
||||
}
|
||||
|
||||
protected onEnd(): void {
|
||||
// 每帧结束时执行
|
||||
Performance.markFrameEnd();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### empty() vs nothing() 的区别
|
||||
|
||||
| 方法 | 行为 | 使用场景 |
|
||||
|------|------|----------|
|
||||
| `Matcher.empty()` | 匹配**所有**实体 | 需要处理场景中所有实体 |
|
||||
| `Matcher.nothing()` | 不匹配**任何**实体 | 只需要生命周期回调,不处理实体 |
|
||||
|
||||
```typescript
|
||||
// empty() - 返回场景中的所有实体
|
||||
class AllEntitiesSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.empty());
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// entities 包含场景中的所有实体
|
||||
console.log(`场景中共有 ${entities.length} 个实体`);
|
||||
}
|
||||
}
|
||||
|
||||
// nothing() - 不返回任何实体
|
||||
class NoEntitiesSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.nothing());
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// entities 永远是空数组,此方法不会被调用
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 按标签查询
|
||||
|
||||
```typescript
|
||||
class PlayerSystem extends EntitySystem {
|
||||
constructor() {
|
||||
// 查询特定标签的实体
|
||||
super(Matcher.empty().withTag(Tags.PLAYER));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 只处理玩家实体
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 按名称查询
|
||||
|
||||
```typescript
|
||||
class BossSystem extends EntitySystem {
|
||||
constructor() {
|
||||
// 查询特定名称的实体
|
||||
super(Matcher.empty().withName('Boss'));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 只处理名为 'Boss' 的实体
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 直接使用 QuerySystem
|
||||
|
||||
如果不需要创建系统,可以直接使用 Scene 的 querySystem 进行查询。
|
||||
|
||||
### 基础查询方法
|
||||
|
||||
```typescript
|
||||
// 获取场景的查询系统
|
||||
const querySystem = scene.querySystem;
|
||||
|
||||
// 查询拥有所有指定组件的实体
|
||||
const result1 = querySystem.queryAll(PositionComponent, VelocityComponent);
|
||||
console.log(`找到 ${result1.count} 个移动实体`);
|
||||
console.log(`查询耗时: ${result1.executionTime.toFixed(2)}ms`);
|
||||
|
||||
// 查询拥有任意指定组件的实体
|
||||
const result2 = querySystem.queryAny(WeaponComponent, MagicComponent);
|
||||
console.log(`找到 ${result2.count} 个战斗单位`);
|
||||
|
||||
// 查询不包含指定组件的实体
|
||||
const result3 = querySystem.queryNone(DeadTag);
|
||||
console.log(`找到 ${result3.count} 个活着的实体`);
|
||||
```
|
||||
|
||||
### 按标签查询
|
||||
|
||||
```typescript
|
||||
const playerResult = querySystem.queryByTag(Tags.PLAYER);
|
||||
for (const player of playerResult.entities) {
|
||||
console.log('玩家:', player.name);
|
||||
}
|
||||
```
|
||||
|
||||
### 按名称查询
|
||||
|
||||
```typescript
|
||||
const bossResult = querySystem.queryByName('Boss');
|
||||
if (bossResult.count > 0) {
|
||||
const boss = bossResult.entities[0];
|
||||
console.log('找到Boss:', boss);
|
||||
}
|
||||
```
|
||||
|
||||
### 按单个组件查询
|
||||
|
||||
```typescript
|
||||
const healthResult = querySystem.queryByComponent(HealthComponent);
|
||||
console.log(`有 ${healthResult.count} 个实体拥有生命值`);
|
||||
```
|
||||
|
||||
## 性能优化
|
||||
|
||||
### 自动缓存
|
||||
|
||||
QuerySystem 内部使用响应式查询自动缓存结果,相同的查询条件会直接使用缓存:
|
||||
|
||||
```typescript
|
||||
// 第一次查询,执行实际查询
|
||||
const result1 = querySystem.queryAll(PositionComponent);
|
||||
console.log('fromCache:', result1.fromCache); // false
|
||||
|
||||
// 第二次相同查询,使用缓存
|
||||
const result2 = querySystem.queryAll(PositionComponent);
|
||||
console.log('fromCache:', result2.fromCache); // true
|
||||
```
|
||||
|
||||
### 实体变化自动更新
|
||||
|
||||
当实体添加/移除组件时,查询缓存会自动更新:
|
||||
|
||||
```typescript
|
||||
// 查询拥有武器的实体
|
||||
const before = querySystem.queryAll(WeaponComponent);
|
||||
console.log('之前:', before.count); // 假设为 5
|
||||
|
||||
// 给实体添加武器
|
||||
const enemy = scene.createEntity('Enemy');
|
||||
enemy.addComponent(new WeaponComponent());
|
||||
|
||||
// 再次查询,自动包含新实体
|
||||
const after = querySystem.queryAll(WeaponComponent);
|
||||
console.log('之后:', after.count); // 现在是 6
|
||||
```
|
||||
|
||||
### 查询性能统计
|
||||
|
||||
```typescript
|
||||
const stats = querySystem.getStats();
|
||||
console.log('总查询次数:', stats.queryStats.totalQueries);
|
||||
console.log('缓存命中率:', stats.queryStats.cacheHitRate);
|
||||
console.log('缓存大小:', stats.cacheStats.size);
|
||||
```
|
||||
|
||||
## 实际应用场景
|
||||
|
||||
### 场景1: 物理系统
|
||||
|
||||
```typescript
|
||||
class PhysicsSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.empty().all(TransformComponent, RigidbodyComponent));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const transform = entity.getComponent(TransformComponent)!;
|
||||
const rigidbody = entity.getComponent(RigidbodyComponent)!;
|
||||
|
||||
// 应用重力
|
||||
rigidbody.velocity.y -= 9.8 * Time.deltaTime;
|
||||
|
||||
// 更新位置
|
||||
transform.position.x += rigidbody.velocity.x * Time.deltaTime;
|
||||
transform.position.y += rigidbody.velocity.y * Time.deltaTime;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 场景2: 渲染系统
|
||||
|
||||
```typescript
|
||||
class RenderSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(
|
||||
Matcher.empty()
|
||||
.all(TransformComponent, SpriteComponent)
|
||||
.none(InvisibleTag) // 排除不可见实体
|
||||
);
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 按 z-order 排序
|
||||
const sorted = entities.slice().sort((a, b) => {
|
||||
const zA = a.getComponent(TransformComponent)!.z;
|
||||
const zB = b.getComponent(TransformComponent)!.z;
|
||||
return zA - zB;
|
||||
});
|
||||
|
||||
// 渲染实体
|
||||
for (const entity of sorted) {
|
||||
const transform = entity.getComponent(TransformComponent)!;
|
||||
const sprite = entity.getComponent(SpriteComponent)!;
|
||||
|
||||
renderer.drawSprite(sprite.texture, transform.position);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 场景3: 碰撞检测
|
||||
|
||||
```typescript
|
||||
class CollisionSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.empty().all(TransformComponent, ColliderComponent));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 简单的 O(n²) 碰撞检测
|
||||
for (let i = 0; i < entities.length; i++) {
|
||||
for (let j = i + 1; j < entities.length; j++) {
|
||||
this.checkCollision(entities[i], entities[j]);
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
private checkCollision(a: Entity, b: Entity): void {
|
||||
const transA = a.getComponent(TransformComponent)!;
|
||||
const transB = b.getComponent(TransformComponent)!;
|
||||
const colliderA = a.getComponent(ColliderComponent)!;
|
||||
const colliderB = b.getComponent(ColliderComponent)!;
|
||||
|
||||
if (this.isOverlapping(transA, colliderA, transB, colliderB)) {
|
||||
// 触发碰撞事件
|
||||
scene.eventSystem.emit('collision', { entityA: a, entityB: b });
|
||||
}
|
||||
}
|
||||
|
||||
private isOverlapping(...args: any[]): boolean {
|
||||
// 碰撞检测逻辑
|
||||
return false;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 场景4: 一次性查询
|
||||
|
||||
```typescript
|
||||
// 在系统外部执行一次性查询
|
||||
class GameManager {
|
||||
private scene: Scene;
|
||||
|
||||
public countEnemies(): number {
|
||||
const result = this.scene.querySystem.queryByTag(Tags.ENEMY);
|
||||
return result.count;
|
||||
}
|
||||
|
||||
public findNearestEnemy(playerPos: Vector2): Entity | null {
|
||||
const enemies = this.scene.querySystem.queryByTag(Tags.ENEMY);
|
||||
|
||||
let nearest: Entity | null = null;
|
||||
let minDistance = Infinity;
|
||||
|
||||
for (const enemy of enemies.entities) {
|
||||
const transform = enemy.getComponent(TransformComponent);
|
||||
if (!transform) continue;
|
||||
|
||||
const distance = Vector2.distance(playerPos, transform.position);
|
||||
if (distance < minDistance) {
|
||||
minDistance = distance;
|
||||
nearest = enemy;
|
||||
}
|
||||
}
|
||||
|
||||
return nearest;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 优先使用 EntitySystem
|
||||
|
||||
```typescript
|
||||
// 推荐: 使用 EntitySystem
|
||||
class GoodSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.empty().all(HealthComponent));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 自动获得符合条件的实体,每帧自动更新
|
||||
}
|
||||
}
|
||||
|
||||
// 不推荐: 在 update 中手动查询
|
||||
class BadSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.empty());
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 每帧手动查询,浪费性能
|
||||
const result = this.scene!.querySystem.queryAll(HealthComponent);
|
||||
for (const entity of result.entities) {
|
||||
// ...
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 合理使用 none() 排除条件
|
||||
|
||||
```typescript
|
||||
// 排除已死亡的敌人
|
||||
class EnemyAISystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(
|
||||
Matcher.empty()
|
||||
.all(EnemyTag, AIComponent)
|
||||
.none(DeadTag) // 不处理死亡的敌人
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 使用标签优化查询
|
||||
|
||||
```typescript
|
||||
// 不好: 查询所有实体再过滤
|
||||
const allEntities = scene.querySystem.getAllEntities();
|
||||
const players = allEntities.filter(e => e.hasComponent(PlayerTag));
|
||||
|
||||
// 好: 直接按标签查询
|
||||
const players = scene.querySystem.queryByTag(Tags.PLAYER).entities;
|
||||
```
|
||||
|
||||
### 4. 避免过于复杂的查询条件
|
||||
|
||||
```typescript
|
||||
// 不推荐: 过于复杂
|
||||
super(
|
||||
Matcher.empty()
|
||||
.all(A, B, C, D)
|
||||
.any(E, F, G)
|
||||
.none(H, I, J)
|
||||
);
|
||||
|
||||
// 推荐: 拆分成多个简单系统
|
||||
class SystemAB extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.empty().all(A, B));
|
||||
}
|
||||
}
|
||||
|
||||
class SystemCD extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.empty().all(C, D));
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 注意事项
|
||||
|
||||
### 1. 查询结果是只读的
|
||||
|
||||
```typescript
|
||||
const result = querySystem.queryAll(PositionComponent);
|
||||
|
||||
// 不要修改返回的数组
|
||||
result.entities.push(someEntity); // 错误!
|
||||
|
||||
// 如果需要修改,先复制
|
||||
const mutableArray = [...result.entities];
|
||||
mutableArray.push(someEntity); // 正确
|
||||
```
|
||||
|
||||
### 2. 组件添加/移除后的查询时机
|
||||
|
||||
```typescript
|
||||
// 创建实体并添加组件
|
||||
const entity = scene.createEntity('Player');
|
||||
entity.addComponent(new PositionComponent());
|
||||
|
||||
// 立即查询可能获取到新实体
|
||||
const result = scene.querySystem.queryAll(PositionComponent);
|
||||
// result.entities 包含新创建的实体
|
||||
```
|
||||
|
||||
### 3. Matcher 是不可变的
|
||||
|
||||
```typescript
|
||||
const matcher = Matcher.empty().all(PositionComponent);
|
||||
|
||||
// 链式调用返回新的 Matcher 实例
|
||||
const matcher2 = matcher.any(VelocityComponent);
|
||||
|
||||
// matcher 本身不变
|
||||
console.log(matcher === matcher2); // false
|
||||
```
|
||||
|
||||

# 实体类
|
||||
|
||||
在 ECS 架构中,实体(Entity)是游戏世界中的基本对象。实体本身不包含游戏逻辑或数据,它只是一个容器,用来组合不同的组件来实现各种功能。
|
||||
|
||||
## 基本概念
|
||||
|
||||
实体是一个轻量级的对象,主要用于:
|
||||
- 作为组件的容器
|
||||
- 提供唯一标识(ID)
|
||||
- 管理组件的生命周期
|
||||
|
||||
::: tip 关于父子层级关系
|
||||
实体间的父子层级关系通过 `HierarchyComponent` 和 `HierarchySystem` 管理,而非 Entity 内置属性。这种设计遵循 ECS 组合原则 —— 只有需要层级关系的实体才添加此组件。
|
||||
|
||||
详见 [层级系统](./hierarchy.md) 文档。
|
||||
:::
|
||||
|
||||
## 创建实体
|
||||
|
||||
**重要提示:实体必须通过场景创建,不支持手动创建!**
|
||||
|
||||
实体必须通过场景的 `createEntity()` 方法来创建,这样才能确保:
|
||||
- 实体被正确添加到场景的实体管理系统中
|
||||
- 实体被添加到查询系统中,供系统使用
|
||||
- 实体获得正确的场景引用
|
||||
- 触发相关的生命周期事件
|
||||
|
||||
```typescript
|
||||
// 正确的方式:通过场景创建实体
|
||||
const player = scene.createEntity("Player");
|
||||
|
||||
// ❌ 错误的方式:手动创建实体
|
||||
// const entity = new Entity("MyEntity", 1); // 这样创建的实体系统无法管理
|
||||
```
|
||||
|
||||
## 添加组件
|
||||
|
||||
实体通过添加组件来获得功能:
|
||||
|
||||
```typescript
|
||||
import { Component, ECSComponent } from '@esengine/ecs-framework';
|
||||
|
||||
// 定义位置组件
|
||||
@ECSComponent('Position')
|
||||
class Position extends Component {
|
||||
x: number = 0;
|
||||
y: number = 0;
|
||||
|
||||
constructor(x: number = 0, y: number = 0) {
|
||||
super();
|
||||
this.x = x;
|
||||
this.y = y;
|
||||
}
|
||||
}
|
||||
|
||||
// 定义健康组件
|
||||
@ECSComponent('Health')
|
||||
class Health extends Component {
|
||||
current: number = 100;
|
||||
max: number = 100;
|
||||
|
||||
constructor(max: number = 100) {
|
||||
super();
|
||||
this.max = max;
|
||||
this.current = max;
|
||||
}
|
||||
}
|
||||
|
||||
// 给实体添加组件
|
||||
const player = scene.createEntity("Player");
|
||||
player.addComponent(new Position(100, 200));
|
||||
player.addComponent(new Health(150));
|
||||
```
|
||||
|
||||
## 获取组件
|
||||
|
||||
```typescript
|
||||
// 获取组件(传入组件类,不是实例)
|
||||
const position = player.getComponent(Position); // 返回 Position | null
|
||||
const health = player.getComponent(Health); // 返回 Health | null
|
||||
|
||||
// 检查组件是否存在
|
||||
if (position) {
|
||||
console.log(`玩家位置: x=${position.x}, y=${position.y}`);
|
||||
}
|
||||
|
||||
// 检查是否有某个组件
|
||||
if (player.hasComponent(Position)) {
|
||||
console.log("玩家有位置组件");
|
||||
}
|
||||
|
||||
// 获取所有组件实例(只读属性)
|
||||
const allComponents = player.components; // readonly Component[]
|
||||
|
||||
// 获取指定类型的所有组件(支持同类型多组件)
|
||||
const allHealthComponents = player.getComponents(Health); // Health[]
|
||||
|
||||
// 获取或创建组件(如果不存在则自动创建)
|
||||
const position = player.getOrCreateComponent(Position, 0, 0); // 传入构造参数
|
||||
const health = player.getOrCreateComponent(Health, 100); // 如果存在则返回现有的,不存在则创建新的
|
||||
```
|
||||
|
||||
## 移除组件
|
||||
|
||||
```typescript
|
||||
// 方式1:通过组件类型移除
|
||||
const removedHealth = player.removeComponentByType(Health);
|
||||
if (removedHealth) {
|
||||
console.log("健康组件已被移除");
|
||||
}
|
||||
|
||||
// 方式2:通过组件实例移除
|
||||
const healthComponent = player.getComponent(Health);
|
||||
if (healthComponent) {
|
||||
player.removeComponent(healthComponent);
|
||||
}
|
||||
|
||||
// 批量移除多种组件类型
|
||||
const removedComponents = player.removeComponentsByTypes([Position, Health]);
|
||||
|
||||
// 检查组件是否被移除
|
||||
if (!player.hasComponent(Health)) {
|
||||
console.log("健康组件已被移除");
|
||||
}
|
||||
```
|
||||
|
||||
## 实体查找
|
||||
|
||||
场景提供了多种方式来查找实体:
|
||||
|
||||
### 通过名称查找
|
||||
|
||||
```typescript
|
||||
// 查找单个实体
|
||||
const player = scene.findEntity("Player");
|
||||
// 或使用别名方法
|
||||
const player2 = scene.getEntityByName("Player");
|
||||
|
||||
if (player) {
|
||||
console.log("找到玩家实体");
|
||||
}
|
||||
```
|
||||
|
||||
### 通过 ID 查找
|
||||
|
||||
```typescript
|
||||
// 通过实体 ID 查找
|
||||
const entity = scene.findEntityById(123);
|
||||
```
|
||||
|
||||
### 通过标签查找
|
||||
|
||||
实体支持标签系统,用于快速分类和查找:
|
||||
|
||||
```typescript
|
||||
// 设置标签
|
||||
player.tag = 1; // 玩家标签
|
||||
enemy.tag = 2; // 敌人标签
|
||||
|
||||
// 通过标签查找所有相关实体
|
||||
const players = scene.findEntitiesByTag(1);
|
||||
const enemies = scene.findEntitiesByTag(2);
|
||||
// 或使用别名方法
|
||||
const allPlayers = scene.getEntitiesByTag(1);
|
||||
```
|
||||
|
||||
|
||||
## 实体生命周期
|
||||
|
||||
```typescript
|
||||
// 销毁实体
|
||||
player.destroy();
|
||||
|
||||
// 检查实体是否已销毁
|
||||
if (player.isDestroyed) {
|
||||
console.log("实体已被销毁");
|
||||
}
|
||||
```
|
||||
|
||||
## 实体事件
|
||||
|
||||
实体的组件变化会触发事件:
|
||||
|
||||
```typescript
|
||||
// 监听组件添加事件
|
||||
scene.eventSystem.on('component:added', (data) => {
|
||||
console.log('组件已添加:', data);
|
||||
});
|
||||
|
||||
// 监听实体创建事件
|
||||
scene.eventSystem.on('entity:created', (data) => {
|
||||
console.log('实体已创建:', data.entityName);
|
||||
});
|
||||
```
|
||||
|
||||
## 性能优化
|
||||
|
||||
|
||||
### 批量创建实体
|
||||
|
||||
框架提供了高性能的批量创建方法:
|
||||
|
||||
```typescript
|
||||
// 批量创建 100 个子弹实体(高性能版本)
|
||||
const bullets = scene.createEntities(100, "Bullet");
|
||||
|
||||
// 为每个子弹添加组件
|
||||
bullets.forEach((bullet, index) => {
|
||||
bullet.addComponent(new Position(Math.random() * 800, Math.random() * 600));
|
||||
bullet.addComponent(new Velocity(Math.random() * 100 - 50, Math.random() * 100 - 50));
|
||||
});
|
||||
```
|
||||
|
||||
`createEntities()` 方法会:
|
||||
- 批量分配实体 ID
|
||||
- 批量添加到实体列表
|
||||
- 优化查询系统更新
|
||||
- 减少系统缓存清理次数
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 合理的组件粒度
|
||||
|
||||
```typescript
|
||||
// 好的做法:功能单一的组件
|
||||
@ECSComponent('Position')
|
||||
class Position extends Component {
|
||||
x: number = 0;
|
||||
y: number = 0;
|
||||
}
|
||||
|
||||
@ECSComponent('Velocity')
|
||||
class Velocity extends Component {
|
||||
dx: number = 0;
|
||||
dy: number = 0;
|
||||
}
|
||||
|
||||
// 避免:功能过于复杂的组件
|
||||
@ECSComponent('Player')
|
||||
class Player extends Component {
|
||||
// 避免在一个组件中包含太多不相关的属性
|
||||
x: number;
|
||||
y: number;
|
||||
health: number;
|
||||
inventory: Item[];
|
||||
skills: Skill[];
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 使用装饰器
|
||||
|
||||
始终使用 `@ECSComponent` 装饰器:
|
||||
|
||||
```typescript
|
||||
@ECSComponent('Transform')
|
||||
class Transform extends Component {
|
||||
// 组件实现
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 合理命名
|
||||
|
||||
```typescript
|
||||
// 清晰的实体命名
|
||||
const mainCharacter = scene.createEntity("MainCharacter");
|
||||
const enemy1 = scene.createEntity("Goblin_001");
|
||||
const collectible = scene.createEntity("HealthPotion");
|
||||
```
|
||||
|
||||
### 4. 及时清理
|
||||
|
||||
```typescript
|
||||
// 不再需要的实体应该及时销毁
|
||||
if (enemy.getComponent(Health).current <= 0) {
|
||||
enemy.destroy();
|
||||
}
|
||||
```
|
||||
|
||||
## 调试实体
|
||||
|
||||
框架提供了调试功能来帮助开发:
|
||||
|
||||
```typescript
|
||||
// 获取实体调试信息
|
||||
const debugInfo = entity.getDebugInfo();
|
||||
console.log('实体信息:', debugInfo);
|
||||
|
||||
// 列出实体的所有组件
|
||||
entity.components.forEach(component => {
|
||||
console.log('组件:', component.constructor.name);
|
||||
});
|
||||
```
|
||||
|
||||
实体是 ECS 架构的核心概念之一,理解如何正确使用实体将帮助你构建高效、可维护的游戏代码。
|
||||
|
||||
## 下一步
|
||||
|
||||
- 了解 [层级系统](./hierarchy.md) 建立实体间的父子关系
|
||||
- 了解 [组件系统](./component.md) 为实体添加功能
|
||||
- 了解 [场景管理](./scene.md) 组织和管理实体

# 事件系统
|
||||
|
||||
ECS 框架内置了强大的类型安全事件系统,支持同步/异步事件、优先级、批处理等高级功能。事件系统是实现组件间通信、系统间协作的核心机制。
|
||||
|
||||
## 基本概念
|
||||
|
||||
事件系统提供了发布-订阅模式的实现,包含以下核心概念:
|
||||
- **事件发布者**:发射事件的对象
|
||||
- **事件监听者**:监听并处理特定事件的对象
|
||||
- **事件类型**:字符串标识,用于区分不同类型的事件
|
||||
- **事件数据**:事件携带的相关信息
|
||||
|
||||
## 事件系统架构
|
||||
|
||||
框架提供了两层事件系统:
|
||||
|
||||
1. **TypeSafeEventSystem** - 底层高性能事件系统
|
||||
2. **EventBus** - 上层增强事件总线,提供更多便利功能
|
||||
|
||||
## 基本使用
|
||||
|
||||
### 在场景中使用事件系统
|
||||
|
||||
每个场景都有内置的事件系统:
|
||||
|
||||
```typescript
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 监听事件
|
||||
this.eventSystem.on('player_died', this.onPlayerDied.bind(this));
|
||||
this.eventSystem.on('enemy_spawned', this.onEnemySpawned.bind(this));
|
||||
this.eventSystem.on('score_changed', this.onScoreChanged.bind(this));
|
||||
}
|
||||
|
||||
private onPlayerDied(data: { player: Entity, cause: string }): void {
|
||||
console.log(`玩家死亡,原因: ${data.cause}`);
|
||||
// 处理玩家死亡逻辑
|
||||
}
|
||||
|
||||
private onEnemySpawned(data: { enemy: Entity, position: { x: number, y: number } }): void {
|
||||
console.log('敌人生成于:', data.position);
|
||||
// 处理敌人生成逻辑
|
||||
}
|
||||
|
||||
private onScoreChanged(data: { newScore: number, oldScore: number }): void {
|
||||
console.log(`分数变化: ${data.oldScore} -> ${data.newScore}`);
|
||||
// 更新UI显示
|
||||
}
|
||||
|
||||
// 在系统中发射事件
|
||||
someGameLogic(): void {
|
||||
// 发射同步事件
|
||||
this.eventSystem.emitSync('score_changed', {
|
||||
newScore: 1000,
|
||||
oldScore: 800
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 在系统中使用事件
|
||||
|
||||
系统可以方便地监听和发送事件:
|
||||
|
||||
```typescript
|
||||
@ECSSystem('Combat')
|
||||
class CombatSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(Health, Combat));
|
||||
}
|
||||
|
||||
protected onInitialize(): void {
|
||||
// 使用系统提供的事件监听方法(自动清理)
|
||||
this.addEventListener('player_attack', this.onPlayerAttack.bind(this));
|
||||
this.addEventListener('enemy_death', this.onEnemyDeath.bind(this));
|
||||
}
|
||||
|
||||
private onPlayerAttack(data: { damage: number, target: Entity }): void {
|
||||
// 处理玩家攻击事件
|
||||
const health = data.target.getComponent(Health);
|
||||
if (health) {
|
||||
health.current -= data.damage;
|
||||
|
||||
if (health.current <= 0) {
|
||||
// 发送敌人死亡事件
|
||||
this.scene?.eventSystem.emitSync('enemy_death', {
|
||||
enemy: data.target,
|
||||
killer: 'player'
|
||||
});
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
private onEnemyDeath(data: { enemy: Entity, killer: string }): void {
|
||||
// 处理敌人死亡
|
||||
data.enemy.destroy();
|
||||
|
||||
// 发送经验奖励事件
|
||||
this.scene?.eventSystem.emitSync('experience_gained', {
|
||||
amount: 100,
|
||||
source: 'enemy_kill'
|
||||
});
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const combat = entity.getComponent(Combat);
|
||||
if (combat && combat.shouldAttack()) {
|
||||
// 发射攻击事件
|
||||
this.scene?.eventSystem.emitSync('player_attack', {
|
||||
damage: combat.damage,
|
||||
target: combat.target
|
||||
});
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 高级功能
|
||||
|
||||
### 一次性监听器
|
||||
|
||||
```typescript
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 只监听一次的事件
|
||||
this.eventSystem.once('game_start', this.onGameStart.bind(this));
|
||||
|
||||
// 或者使用配置对象
|
||||
this.eventSystem.on('level_complete', this.onLevelComplete.bind(this), {
|
||||
once: true // 只执行一次
|
||||
});
|
||||
}
|
||||
|
||||
private onGameStart(): void {
|
||||
console.log('游戏开始!');
|
||||
// 这个方法只会被调用一次
|
||||
}
|
||||
|
||||
private onLevelComplete(): void {
|
||||
console.log('关卡完成!');
|
||||
// 这个方法也只会被调用一次
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 优先级控制
|
||||
|
||||
```typescript
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 高优先级监听器先执行
|
||||
this.eventSystem.on('damage_dealt', this.onDamageDealt.bind(this), {
|
||||
priority: 100 // 高优先级
|
||||
});
|
||||
|
||||
// 普通优先级
|
||||
this.eventSystem.on('damage_dealt', this.updateUI.bind(this), {
|
||||
priority: 0 // 默认优先级
|
||||
});
|
||||
|
||||
// 低优先级最后执行
|
||||
this.eventSystem.on('damage_dealt', this.logDamage.bind(this), {
|
||||
priority: -100 // 低优先级
|
||||
});
|
||||
}
|
||||
|
||||
private onDamageDealt(data: any): void {
|
||||
// 最先执行 - 处理核心游戏逻辑
|
||||
}
|
||||
|
||||
private updateUI(data: any): void {
|
||||
// 中等优先级 - 更新界面
|
||||
}
|
||||
|
||||
private logDamage(data: any): void {
|
||||
// 最后执行 - 记录日志
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 异步事件处理
|
||||
|
||||
```typescript
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 监听异步事件
|
||||
this.eventSystem.onAsync('save_game', this.onSaveGame.bind(this));
|
||||
this.eventSystem.onAsync('load_data', this.onLoadData.bind(this));
|
||||
}
|
||||
|
||||
private async onSaveGame(data: { saveSlot: number }): Promise<void> {
|
||||
console.log(`开始保存游戏到槽位 ${data.saveSlot}`);
|
||||
|
||||
// 模拟异步保存操作
|
||||
await this.saveGameData(data.saveSlot);
|
||||
|
||||
console.log('游戏保存完成');
|
||||
}
|
||||
|
||||
private async onLoadData(data: { url: string }): Promise<void> {
|
||||
try {
|
||||
const response = await fetch(data.url);
|
||||
const gameData = await response.json();
|
||||
// 处理加载的数据
|
||||
} catch (error) {
|
||||
console.error('数据加载失败:', error);
|
||||
}
|
||||
}
|
||||
|
||||
private async saveGameData(slot: number): Promise<void> {
|
||||
// 模拟保存操作
|
||||
return new Promise(resolve => setTimeout(resolve, 1000));
|
||||
}
|
||||
|
||||
// 发射异步事件
|
||||
public async triggerSave(): Promise<void> {
|
||||
// 使用 emit 而不是 emitSync 来触发异步监听器
|
||||
await this.eventSystem.emit('save_game', { saveSlot: 1 });
|
||||
console.log('所有异步保存操作完成');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 事件统计和调试
|
||||
|
||||
```typescript
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
this.eventSystem.on('debug_event', this.onDebugEvent.bind(this));
|
||||
}
|
||||
|
||||
private onDebugEvent(): void {
|
||||
// 处理调试事件
|
||||
}
|
||||
|
||||
public showEventStats(): void {
|
||||
// 获取特定事件的统计信息
|
||||
const stats = this.eventSystem.getStats('debug_event') as any;
|
||||
if (stats) {
|
||||
console.log('事件统计:');
|
||||
console.log(`- 事件类型: ${stats.eventType}`);
|
||||
console.log(`- 监听器数量: ${stats.listenerCount}`);
|
||||
console.log(`- 触发次数: ${stats.triggerCount}`);
|
||||
console.log(`- 平均执行时间: ${stats.averageExecutionTime.toFixed(2)}ms`);
|
||||
}
|
||||
|
||||
// 获取所有事件统计
|
||||
const allStats = this.eventSystem.getStats() as Map<string, any>;
|
||||
console.log(`总共有 ${allStats.size} 种事件类型`);
|
||||
}
|
||||
|
||||
public resetEventStats(): void {
|
||||
// 重置特定事件的统计
|
||||
this.eventSystem.resetStats('debug_event');
|
||||
|
||||
// 或重置所有统计
|
||||
this.eventSystem.resetStats();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 全局事件总线
|
||||
|
||||
对于跨场景的事件通信,可以使用全局事件总线:
|
||||
|
||||
```typescript
|
||||
import { GlobalEventBus } from '@esengine/ecs-framework';
|
||||
|
||||
class GameManager {
|
||||
private eventBus = GlobalEventBus.getInstance();
|
||||
|
||||
constructor() {
|
||||
this.setupGlobalEvents();
|
||||
}
|
||||
|
||||
private setupGlobalEvents(): void {
|
||||
// 监听全局事件
|
||||
this.eventBus.on('player_level_up', this.onPlayerLevelUp.bind(this));
|
||||
this.eventBus.on('achievement_unlocked', this.onAchievementUnlocked.bind(this));
|
||||
this.eventBus.onAsync('upload_score', this.onUploadScore.bind(this));
|
||||
}
|
||||
|
||||
private onPlayerLevelUp(data: { level: number, experience: number }): void {
|
||||
console.log(`玩家升级到 ${data.level} 级!`);
|
||||
// 处理全局升级逻辑
|
||||
}
|
||||
|
||||
private onAchievementUnlocked(data: { achievementId: string, name: string }): void {
|
||||
console.log(`解锁成就: ${data.name}`);
|
||||
// 显示成就通知
|
||||
}
|
||||
|
||||
private async onUploadScore(data: { score: number, playerName: string }): Promise<void> {
|
||||
// 异步上传分数到服务器
|
||||
try {
|
||||
await this.uploadToServer(data);
|
||||
console.log('分数上传成功');
|
||||
} catch (error) {
|
||||
console.error('分数上传失败:', error);
|
||||
}
|
||||
}
|
||||
|
||||
public triggerGlobalEvent(): void {
|
||||
// 发射全局事件
|
||||
this.eventBus.emit('player_level_up', {
|
||||
level: 10,
|
||||
experience: 2500
|
||||
});
|
||||
}
|
||||
|
||||
private async uploadToServer(data: any): Promise<void> {
|
||||
// 模拟服务器上传
|
||||
return new Promise(resolve => setTimeout(resolve, 2000));
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 批处理事件
|
||||
|
||||
对于高频事件,可以使用批处理来提升性能:
|
||||
|
||||
```typescript
|
||||
class MovementSystem extends EntitySystem {
|
||||
protected onInitialize(): void {
|
||||
// 设置位置更新事件的批处理
|
||||
this.scene?.eventSystem.setBatchConfig('position_updated', {
|
||||
batchSize: 50, // 批处理大小
|
||||
delay: 16, // 延迟时间(毫秒)
|
||||
enabled: true
|
||||
});
|
||||
|
||||
// 监听批处理事件
|
||||
this.addEventListener('position_updated:batch', this.onPositionBatch.bind(this));
|
||||
}
|
||||
|
||||
private onPositionBatch(batchData: any): void {
|
||||
console.log(`批处理位置更新,共 ${batchData.count} 个事件`);
|
||||
|
||||
// 批量处理所有位置更新
|
||||
for (const event of batchData.events) {
|
||||
this.updateMinimap(event.entityId, event.position);
|
||||
}
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const position = entity.getComponent(Position);
|
||||
if (position && position.hasChanged) {
|
||||
// 发射高频位置更新事件(会被批处理)
|
||||
this.scene?.eventSystem.emitSync('position_updated', {
|
||||
entityId: entity.id,
|
||||
position: { x: position.x, y: position.y }
|
||||
});
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
private updateMinimap(entityId: number, position: { x: number, y: number }): void {
|
||||
// 更新小地图显示
|
||||
}
|
||||
|
||||
public flushPositionUpdates(): void {
|
||||
// 立即处理所有待处理的位置更新
|
||||
this.scene?.eventSystem.flushBatch('position_updated');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 预定义的 ECS 事件
|
||||
|
||||
框架提供了一些预定义的 ECS 生命周期事件:
|
||||
|
||||
```typescript
|
||||
import { ECSEventType } from '@esengine/ecs-framework';
|
||||
|
||||
class ECSMonitor {
|
||||
private eventBus = GlobalEventBus.getInstance();
|
||||
|
||||
constructor() {
|
||||
this.setupECSEvents();
|
||||
}
|
||||
|
||||
private setupECSEvents(): void {
|
||||
// 监听实体生命周期事件
|
||||
this.eventBus.onEntityCreated(this.onEntityCreated.bind(this));
|
||||
this.eventBus.on(ECSEventType.ENTITY_DESTROYED, this.onEntityDestroyed.bind(this));
|
||||
|
||||
// 监听组件生命周期事件
|
||||
this.eventBus.onComponentAdded(this.onComponentAdded.bind(this));
|
||||
this.eventBus.on(ECSEventType.COMPONENT_REMOVED, this.onComponentRemoved.bind(this));
|
||||
|
||||
// 监听系统事件
|
||||
this.eventBus.on(ECSEventType.SYSTEM_ADDED, this.onSystemAdded.bind(this));
|
||||
this.eventBus.onSystemError(this.onSystemError.bind(this));
|
||||
|
||||
// 监听性能警告
|
||||
this.eventBus.onPerformanceWarning(this.onPerformanceWarning.bind(this));
|
||||
}
|
||||
|
||||
private onEntityCreated(data: any): void {
|
||||
console.log(`实体创建: ${data.entityName} (ID: ${data.entity.id})`);
|
||||
}
|
||||
|
||||
private onEntityDestroyed(data: any): void {
|
||||
console.log(`实体销毁: ${data.entity.name} (ID: ${data.entity.id})`);
|
||||
}
|
||||
|
||||
private onComponentAdded(data: any): void {
|
||||
console.log(`组件添加: ${data.componentType} 到实体 ${data.entity.name}`);
|
||||
}
|
||||
|
||||
private onComponentRemoved(data: any): void {
|
||||
console.log(`组件移除: ${data.componentType} 从实体 ${data.entity.name}`);
|
||||
}
|
||||
|
||||
private onSystemAdded(data: any): void {
|
||||
console.log(`系统添加: ${data.systemName}`);
|
||||
}
|
||||
|
||||
private onSystemError(data: any): void {
|
||||
console.error(`系统错误: ${data.systemName}`, data.error);
|
||||
}
|
||||
|
||||
private onPerformanceWarning(data: any): void {
|
||||
console.warn(`性能警告: ${data.systemName} 执行时间过长 (${data.executionTime}ms)`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 事件命名规范
|
||||
|
||||
```typescript
|
||||
// ✅ 好的事件命名
|
||||
this.eventSystem.emitSync('player:health_changed', data);
|
||||
this.eventSystem.emitSync('enemy:spawned', data);
|
||||
this.eventSystem.emitSync('ui:score_updated', data);
|
||||
this.eventSystem.emitSync('game:paused', data);
|
||||
|
||||
// ❌ 避免的事件命名
|
||||
this.eventSystem.emitSync('event1', data);
|
||||
this.eventSystem.emitSync('update', data);
|
||||
this.eventSystem.emitSync('change', data);
|
||||
```
|
||||
|
||||
### 2. 类型安全的事件数据
|
||||
|
||||
```typescript
|
||||
// 定义事件数据接口
|
||||
interface PlayerHealthChangedEvent {
|
||||
entityId: number;
|
||||
oldHealth: number;
|
||||
newHealth: number;
|
||||
cause: 'damage' | 'healing';
|
||||
}
|
||||
|
||||
interface EnemySpawnedEvent {
|
||||
enemyType: string;
|
||||
position: { x: number, y: number };
|
||||
level: number;
|
||||
}
|
||||
|
||||
// 使用类型安全的事件
|
||||
class HealthSystem extends EntitySystem {
|
||||
private onHealthChanged(data: PlayerHealthChangedEvent): void {
|
||||
// TypeScript 会提供完整的类型检查
|
||||
console.log(`生命值变化: ${data.oldHealth} -> ${data.newHealth}`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 避免事件循环
|
||||
|
||||
```typescript
|
||||
// ❌ 避免:可能导致无限循环
|
||||
class BadEventHandler {
|
||||
private onScoreChanged(data: any): void {
|
||||
// 在处理分数变化时又触发分数变化事件
|
||||
this.scene?.eventSystem.emitSync('score_changed', newData); // 危险!
|
||||
}
|
||||
}
|
||||
|
||||
// ✅ 正确:使用不同的事件类型或条件判断
|
||||
class GoodEventHandler {
|
||||
private isProcessingScore = false;
|
||||
|
||||
private onScoreChanged(data: any): void {
|
||||
if (this.isProcessingScore) return; // 防止循环
|
||||
|
||||
this.isProcessingScore = true;
|
||||
// 处理分数变化
|
||||
this.updateUI(data);
|
||||
this.isProcessingScore = false;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 及时清理事件监听器
|
||||
|
||||
```typescript
|
||||
class TemporaryUI {
|
||||
private listenerId: string;
|
||||
|
||||
constructor(scene: Scene) {
|
||||
// 保存监听器ID用于后续清理
|
||||
this.listenerId = scene.eventSystem.on('ui_update', this.onUpdate.bind(this));
|
||||
}
|
||||
|
||||
private onUpdate(data: any): void {
|
||||
// 处理UI更新
|
||||
}
|
||||
|
||||
public destroy(): void {
|
||||
// 清理事件监听器
|
||||
if (this.listenerId) {
|
||||
scene.eventSystem.off('ui_update', this.listenerId);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 5. 性能考虑
|
||||
|
||||
```typescript
|
||||
class OptimizedEventHandler {
|
||||
protected onInitialize(): void {
|
||||
// 对于高频事件,使用批处理
|
||||
this.scene?.eventSystem.setBatchConfig('movement_update', {
|
||||
batchSize: 100,
|
||||
delay: 16,
|
||||
enabled: true
|
||||
});
|
||||
|
||||
// 对于低频但重要的事件,使用高优先级
|
||||
this.addEventListener('game_over', this.onGameOver.bind(this), {
|
||||
priority: 1000
|
||||
});
|
||||
|
||||
// 对于一次性事件,使用 once
|
||||
this.addEventListener('level_start', this.onLevelStart.bind(this), {
|
||||
once: true
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
事件系统是 ECS 框架中实现松耦合架构的重要工具,正确使用事件系统能让你的游戏代码更加模块化、可维护和可扩展。

# 快速开始
|
||||
|
||||
本指南将帮助你快速上手 ECS Framework,从安装到创建第一个 ECS 应用。
|
||||
|
||||
## 安装
|
||||
|
||||
### NPM 安装
|
||||
|
||||
```bash
|
||||
# 使用 npm
|
||||
npm install @esengine/ecs-framework
|
||||
```
|
||||
|
||||
## 初始化 Core
|
||||
|
||||
### 基础初始化
|
||||
|
||||
ECS Framework 的核心是 `Core` 类,它是一个单例模式,负责管理整个框架的生命周期。
|
||||
|
||||
```typescript
|
||||
import { Core } from '@esengine/ecs-framework'
|
||||
|
||||
// 方式1:使用配置对象(推荐)
|
||||
const core = Core.create({
|
||||
debug: true, // 启用调试模式,提供详细的日志和性能监控
|
||||
debugConfig: { // 可选:高级调试配置
|
||||
enabled: false, // 是否启用WebSocket调试服务器
|
||||
websocketUrl: 'ws://localhost:8080',
|
||||
debugFrameRate: 30, // 调试数据发送帧率
|
||||
channels: {
|
||||
entities: true,
|
||||
systems: true,
|
||||
performance: true,
|
||||
components: true,
|
||||
scenes: true
|
||||
}
|
||||
}
|
||||
});
|
||||
|
||||
// 方式2:简化创建(向后兼容)
|
||||
const core = Core.create(true); // 等同于 { debug: true }
|
||||
|
||||
// 方式3:生产环境配置
|
||||
const core = Core.create({
|
||||
debug: false // 生产环境关闭调试
|
||||
});
|
||||
```
|
||||
|
||||
### Core 配置详解
|
||||
|
||||
```typescript
|
||||
interface ICoreConfig {
|
||||
/** 是否启用调试模式 - 影响日志级别和性能监控 */
|
||||
debug?: boolean;
|
||||
|
||||
/** 高级调试配置 - 用于开发工具集成 */
|
||||
debugConfig?: {
|
||||
enabled: boolean; // 是否启用调试服务器
|
||||
websocketUrl: string; // WebSocket服务器地址
|
||||
autoReconnect?: boolean; // 是否自动重连
|
||||
debugFrameRate?: 60 | 30 | 15; // 调试数据发送帧率
|
||||
channels: { // 数据通道配置
|
||||
entities: boolean; // 实体数据
|
||||
systems: boolean; // 系统数据
|
||||
performance: boolean; // 性能数据
|
||||
components: boolean; // 组件数据
|
||||
scenes: boolean; // 场景数据
|
||||
};
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### Core 实例管理
|
||||
|
||||
Core 采用单例模式,创建后可以通过静态属性获取:
|
||||
|
||||
```typescript
|
||||
// 创建实例
|
||||
const core = Core.create(true);
|
||||
|
||||
// 获取已创建的实例
|
||||
const instance = Core.Instance; // 获取当前实例,如果未创建则为 null
|
||||
```
|
||||
|
||||
### 游戏循环集成
|
||||
|
||||
**重要**: 在创建实体和系统之前,你需要先了解如何将 ECS Framework 集成到你的游戏引擎中。
|
||||
|
||||
`Core.update(deltaTime)` 是整个框架的心跳,必须在游戏引擎的每一帧中调用。它负责:
|
||||
- 更新框架内置的 Time 类
|
||||
- 更新所有全局管理器(定时器、对象池等)
|
||||
- 更新所有场景中的实体系统
|
||||
- 处理实体的创建和销毁
|
||||
- 收集性能数据(调试模式下)
|
||||
|
||||
各引擎集成示例请参考:[与游戏引擎集成](#与游戏引擎集成)
|
||||
|
||||
## 创建第一个 ECS 应用
|
||||
|
||||
### 1. 定义组件
|
||||
|
||||
组件是纯数据容器,用于存储实体的状态:
|
||||
|
||||
```typescript
|
||||
import { Component, ECSComponent } from '@esengine/ecs-framework'
|
||||
|
||||
// 位置组件
|
||||
@ECSComponent('Position')
|
||||
class Position extends Component {
|
||||
x: number = 0
|
||||
y: number = 0
|
||||
|
||||
constructor(x: number = 0, y: number = 0) {
|
||||
super()
|
||||
this.x = x
|
||||
this.y = y
|
||||
}
|
||||
}
|
||||
|
||||
// 速度组件
|
||||
@ECSComponent('Velocity')
|
||||
class Velocity extends Component {
|
||||
dx: number = 0
|
||||
dy: number = 0
|
||||
|
||||
constructor(dx: number = 0, dy: number = 0) {
|
||||
super()
|
||||
this.dx = dx
|
||||
this.dy = dy
|
||||
}
|
||||
}
|
||||
|
||||
// 渲染组件
|
||||
@ECSComponent('Sprite')
|
||||
class Sprite extends Component {
|
||||
texture: string = ''
|
||||
width: number = 32
|
||||
height: number = 32
|
||||
|
||||
constructor(texture: string, width: number = 32, height: number = 32) {
|
||||
super()
|
||||
this.texture = texture
|
||||
this.width = width
|
||||
this.height = height
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 创建实体系统
|
||||
|
||||
系统包含游戏逻辑,处理具有特定组件的实体。ECS Framework 提供了基于 Matcher 的实体过滤机制:
|
||||
|
||||
```typescript
|
||||
import { EntitySystem, Matcher, Time, ECSSystem } from '@esengine/ecs-framework'
|
||||
|
||||
// 移动系统 - 处理位置和速度
|
||||
@ECSSystem('MovementSystem')
|
||||
class MovementSystem extends EntitySystem {
|
||||
|
||||
constructor() {
|
||||
// 使用 Matcher 定义要处理的实体:必须同时拥有 Position 和 Velocity 组件
|
||||
super(Matcher.empty().all(Position, Velocity))
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// process 方法接收所有匹配的实体
|
||||
for (const entity of entities) {
|
||||
const position = entity.getComponent(Position)!
|
||||
const velocity = entity.getComponent(Velocity)!
|
||||
|
||||
// 更新位置(使用框架的Time类)
|
||||
position.x += velocity.dx * Time.deltaTime
|
||||
position.y += velocity.dy * Time.deltaTime
|
||||
|
||||
// 边界检查示例
|
||||
if (position.x < 0) position.x = 0
|
||||
if (position.y < 0) position.y = 0
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// 渲染系统 - 处理可见对象
|
||||
@ECSSystem('RenderSystem')
|
||||
class RenderSystem extends EntitySystem {
|
||||
|
||||
constructor() {
|
||||
// 必须有 Position 和 Sprite,可选 Velocity(用于方向判断)
|
||||
super(Matcher.empty().all(Position, Sprite).any(Velocity))
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const position = entity.getComponent(Position)!
|
||||
const sprite = entity.getComponent(Sprite)!
|
||||
const velocity = entity.getComponent(Velocity) // 可能为 null
|
||||
|
||||
// 根据速度方向翻转精灵(可选逻辑)
|
||||
let flipX = false
|
||||
if (velocity && velocity.dx < 0) {
|
||||
flipX = true
|
||||
}
|
||||
|
||||
// 渲染逻辑(这里是伪代码)
|
||||
this.drawSprite(sprite.texture, position.x, position.y, sprite.width, sprite.height, flipX)
|
||||
}
|
||||
}
|
||||
|
||||
private drawSprite(texture: string, x: number, y: number, width: number, height: number, flipX: boolean = false) {
|
||||
// 实际的渲染实现将取决于你使用的游戏引擎
|
||||
const direction = flipX ? '←' : '→'
|
||||
console.log(`渲染 ${texture} 在位置 (${x.toFixed(1)}, ${y.toFixed(1)}) 方向: ${direction}`)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
### 3. 创建场景
|
||||
|
||||
推荐继承 Scene 类来创建自定义场景:
|
||||
|
||||
```typescript
|
||||
import { Scene } from '@esengine/ecs-framework'
|
||||
|
||||
// 推荐:继承Scene创建自定义场景
|
||||
class GameScene extends Scene {
|
||||
|
||||
initialize(): void {
|
||||
// 场景初始化逻辑
|
||||
this.name = "MainScene";
|
||||
|
||||
// 添加系统到场景
|
||||
this.addSystem(new MovementSystem());
|
||||
this.addSystem(new RenderSystem());
|
||||
}
|
||||
|
||||
onStart(): void {
|
||||
// 场景开始运行时的逻辑
|
||||
console.log("游戏场景已启动");
|
||||
}
|
||||
|
||||
unload(): void {
|
||||
// 场景卸载时的清理逻辑
|
||||
console.log("游戏场景已卸载");
|
||||
}
|
||||
}
|
||||
|
||||
// 创建并设置场景
|
||||
const gameScene = new GameScene();
|
||||
Core.setScene(gameScene);
|
||||
```
|
||||
|
||||
### 4. 创建实体
|
||||
|
||||
```typescript
|
||||
// 创建玩家实体
|
||||
const player = gameScene.createEntity("Player");
|
||||
player.addComponent(new Position(100, 100));
|
||||
player.addComponent(new Velocity(50, 30)); // 每秒移动 50 像素(x方向),30 像素(y方向)
|
||||
player.addComponent(new Sprite("player.png", 64, 64));
|
||||
```
|
||||
|
||||
## 场景管理
|
||||
|
||||
Core 内置了场景管理功能,使用非常简单:
|
||||
|
||||
```typescript
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
|
||||
// 初始化Core
|
||||
Core.create({ debug: true });
|
||||
|
||||
// 创建并设置场景
|
||||
class GameScene extends Scene {
|
||||
initialize(): void {
|
||||
this.name = "GamePlay";
|
||||
this.addSystem(new MovementSystem());
|
||||
this.addSystem(new RenderSystem());
|
||||
}
|
||||
}
|
||||
|
||||
const gameScene = new GameScene();
|
||||
Core.setScene(gameScene);
|
||||
|
||||
// 游戏循环(自动更新场景)
|
||||
function gameLoop(deltaTime: number) {
|
||||
Core.update(deltaTime); // 自动更新全局服务和场景
|
||||
}
|
||||
|
||||
// 切换场景
|
||||
Core.loadScene(new MenuScene()); // 延迟切换(下一帧)
|
||||
Core.setScene(new GameScene()); // 立即切换
|
||||
|
||||
// 访问当前场景
|
||||
const currentScene = Core.scene;
|
||||
|
||||
// 使用流式API
|
||||
const player = Core.ecsAPI?.createEntity('Player')
|
||||
.addComponent(Position, 100, 100)
|
||||
.addComponent(Velocity, 50, 0);
|
||||
```
|
||||
|
||||
### 高级:使用 WorldManager 管理多世界
|
||||
|
||||
仅适用于复杂的服务器端应用(MMO游戏服务器、游戏房间系统等):
|
||||
|
||||
```typescript
|
||||
import { Core, WorldManager } from '@esengine/ecs-framework';
|
||||
|
||||
// 初始化Core
|
||||
Core.create({ debug: true });
|
||||
|
||||
// 从服务容器获取 WorldManager(Core 已自动创建并注册)
|
||||
const worldManager = Core.services.resolve(WorldManager);
|
||||
|
||||
// 创建多个独立的游戏世界
|
||||
const room1 = worldManager.createWorld('room_001');
|
||||
const room2 = worldManager.createWorld('room_002');
|
||||
|
||||
// 在每个世界中创建场景
|
||||
const gameScene1 = room1.createScene('game', new GameScene());
|
||||
const gameScene2 = room2.createScene('game', new GameScene());
|
||||
|
||||
// 激活场景
|
||||
room1.setSceneActive('game', true);
|
||||
room2.setSceneActive('game', true);
|
||||
|
||||
// 游戏循环(需要手动更新世界)
|
||||
function gameLoop(deltaTime: number) {
|
||||
Core.update(deltaTime); // 更新全局服务
|
||||
worldManager.updateAll(); // 手动更新所有世界
|
||||
}
|
||||
```
|
||||
|
||||
## 与游戏引擎集成
|
||||
|
||||
### Laya 引擎集成
|
||||
|
||||
```typescript
|
||||
import { Stage } from "laya/display/Stage";
|
||||
import { Laya } from "Laya";
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
|
||||
// 初始化 Laya
|
||||
Laya.init(800, 600).then(() => {
|
||||
// 初始化 ECS
|
||||
Core.create(true);
|
||||
Core.setScene(new GameScene());
|
||||
|
||||
// 启动游戏循环
|
||||
Laya.timer.frameLoop(1, this, () => {
|
||||
const deltaTime = Laya.timer.delta / 1000;
|
||||
Core.update(deltaTime); // 自动更新全局服务和场景
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### Cocos Creator 集成
|
||||
|
||||
```typescript
|
||||
import { Component, _decorator } from 'cc';
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
|
||||
const { ccclass } = _decorator;
|
||||
|
||||
@ccclass('ECSGameManager')
|
||||
export class ECSGameManager extends Component {
|
||||
onLoad() {
|
||||
// 初始化 ECS
|
||||
Core.create(true);
|
||||
Core.setScene(new GameScene());
|
||||
}
|
||||
|
||||
update(deltaTime: number) {
|
||||
// 自动更新全局服务和场景
|
||||
Core.update(deltaTime);
|
||||
}
|
||||
|
||||
onDestroy() {
|
||||
// 清理资源
|
||||
Core.destroy();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 下一步
|
||||
|
||||
现在你已经成功创建了第一个 ECS 应用!接下来可以:
|
||||
|
||||

|
||||
- 探索更多[实际应用示例](/examples/)
|
||||
|
||||
## 常见问题
|
||||
|
||||
### 为什么我的系统没有执行?
|
||||
|
||||
确保:
|
||||
1. 系统已添加到场景:`this.addSystem(system)` (在 Scene 的 initialize 方法中)
|
||||
2. 场景已设置:`Core.setScene(scene)`
|
||||
3. 游戏循环在调用:`Core.update(deltaTime)`
|
||||
|
||||
### 如何调试 ECS 应用?
|
||||
|
||||
启用调试模式:
|
||||
|
||||
```typescript
|
||||
Core.create({ debug: true })
|
||||
|
||||
// 获取调试数据
|
||||
const debugData = Core.getDebugData()
|
||||
console.log(debugData)
|
||||
```

# 层级系统
|
||||
|
||||
在游戏开发中,实体间的父子层级关系是常见需求。ECS Framework 采用组件化方式管理层级关系,通过 `HierarchyComponent` 和 `HierarchySystem` 实现,完全遵循 ECS 组合原则。
|
||||
|
||||
## 设计理念
|
||||
|
||||
### 为什么不在 Entity 中内置层级?
|
||||
|
||||
传统的游戏对象模型(如 Unity 的 GameObject)将层级关系内置于实体中。ECS Framework 选择组件化方案的原因:
|
||||
|
||||
1. **ECS 组合原则**:层级是一种"功能",应该通过组件添加,而非所有实体都具备
|
||||
2. **按需使用**:只有需要层级关系的实体才添加 `HierarchyComponent`
|
||||
3. **数据与逻辑分离**:`HierarchyComponent` 存储数据,`HierarchySystem` 处理逻辑
|
||||
4. **序列化友好**:层级关系作为组件数据可以轻松序列化和反序列化
|
||||
|
||||
## 基本概念
|
||||
|
||||
### HierarchyComponent
|
||||
|
||||
存储层级关系数据的组件:
|
||||
|
||||
```typescript
|
||||
import { HierarchyComponent } from '@esengine/ecs-framework';
|
||||
|
||||
// HierarchyComponent 的核心属性
|
||||
interface HierarchyComponent {
|
||||
parentId: number | null; // 父实体 ID,null 表示根实体
|
||||
childIds: number[]; // 子实体 ID 列表
|
||||
depth: number; // 在层级中的深度(由系统维护)
|
||||
bActiveInHierarchy: boolean; // 在层级中是否激活(由系统维护)
|
||||
}
|
||||
```
|
||||
|
||||
### HierarchySystem
|
||||
|
||||
处理层级逻辑的系统,提供所有层级操作的 API:
|
||||
|
||||
```typescript
|
||||
import { HierarchySystem } from '@esengine/ecs-framework';
|
||||
|
||||
// 获取系统
|
||||
const hierarchySystem = scene.getEntityProcessor(HierarchySystem);
|
||||
```
|
||||
|
||||
## 快速开始
|
||||
|
||||
### 添加系统到场景
|
||||
|
||||
```typescript
|
||||
import { Scene, HierarchySystem } from '@esengine/ecs-framework';
|
||||
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 添加层级系统
|
||||
this.addSystem(new HierarchySystem());
|
||||
|
||||
// 添加其他系统...
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 建立父子关系
|
||||
|
||||
```typescript
|
||||
// 创建实体
|
||||
const parent = scene.createEntity("Parent");
|
||||
const child1 = scene.createEntity("Child1");
|
||||
const child2 = scene.createEntity("Child2");
|
||||
|
||||
// 获取层级系统
|
||||
const hierarchySystem = scene.getEntityProcessor(HierarchySystem);
|
||||
|
||||
// 设置父子关系(自动添加 HierarchyComponent)
|
||||
hierarchySystem.setParent(child1, parent);
|
||||
hierarchySystem.setParent(child2, parent);
|
||||
|
||||
// 现在 parent 有两个子实体
|
||||
```
|
||||
|
||||
### 查询层级
|
||||
|
||||
```typescript
|
||||
// 获取父实体
|
||||
const parentEntity = hierarchySystem.getParent(child1);
|
||||
|
||||
// 获取所有子实体
|
||||
const children = hierarchySystem.getChildren(parent);
|
||||
|
||||
// 获取子实体数量
|
||||
const count = hierarchySystem.getChildCount(parent);
|
||||
|
||||
// 检查是否有子实体
|
||||
const hasKids = hierarchySystem.hasChildren(parent);
|
||||
|
||||
// 获取在层级中的深度
|
||||
const depth = hierarchySystem.getDepth(child1); // 返回 1
|
||||
```
|
||||
|
||||
## API 参考
|
||||
|
||||
### 父子关系操作
|
||||
|
||||
#### setParent
|
||||
|
||||
设置实体的父级:
|
||||
|
||||
```typescript
|
||||
// 设置父级
|
||||
hierarchySystem.setParent(child, parent);
|
||||
|
||||
// 移动到根级(无父级)
|
||||
hierarchySystem.setParent(child, null);
|
||||
```
|
||||
|
||||
#### insertChildAt
|
||||
|
||||
在指定位置插入子实体:
|
||||
|
||||
```typescript
|
||||
// 在第一个位置插入
|
||||
hierarchySystem.insertChildAt(parent, child, 0);
|
||||
|
||||
// 追加到末尾
|
||||
hierarchySystem.insertChildAt(parent, child, -1);
|
||||
```
|
||||
|
||||
#### removeChild
|
||||
|
||||
从父级移除子实体(子实体变为根级):
|
||||
|
||||
```typescript
|
||||
const success = hierarchySystem.removeChild(parent, child);
|
||||
```
|
||||
|
||||
#### removeAllChildren
|
||||
|
||||
移除所有子实体:
|
||||
|
||||
```typescript
|
||||
hierarchySystem.removeAllChildren(parent);
|
||||
```
|
||||
|
||||
### 层级查询
|
||||
|
||||
#### getParent / getChildren
|
||||
|
||||
```typescript
|
||||
const parent = hierarchySystem.getParent(entity);
|
||||
const children = hierarchySystem.getChildren(entity);
|
||||
```
|
||||
|
||||
#### getRoot
|
||||
|
||||
获取实体的根节点:
|
||||
|
||||
```typescript
|
||||
const root = hierarchySystem.getRoot(deepChild);
|
||||
```
|
||||
|
||||
#### getRootEntities
|
||||
|
||||
获取所有根实体(没有父级的实体):
|
||||
|
||||
```typescript
|
||||
const roots = hierarchySystem.getRootEntities();
|
||||
```
|
||||
|
||||
#### isAncestorOf / isDescendantOf
|
||||
|
||||
检查祖先/后代关系:
|
||||
|
||||
```typescript
|
||||
// grandparent -> parent -> child
|
||||
const isAncestor = hierarchySystem.isAncestorOf(grandparent, child); // true
|
||||
const isDescendant = hierarchySystem.isDescendantOf(child, grandparent); // true
|
||||
```
|
||||
|
||||
### 层级遍历
|
||||
|
||||
#### findChild
|
||||
|
||||
根据名称查找子实体:
|
||||
|
||||
```typescript
|
||||
// 直接子级中查找
|
||||
const child = hierarchySystem.findChild(parent, "ChildName");
|
||||
|
||||
// 递归查找所有后代
|
||||
const deepChild = hierarchySystem.findChild(parent, "DeepChild", true);
|
||||
```
|
||||
|
||||
#### findChildrenByTag
|
||||
|
||||
根据标签查找子实体:
|
||||
|
||||
```typescript
|
||||
// 查找直接子级
|
||||
const tagged = hierarchySystem.findChildrenByTag(parent, TAG_ENEMY);
|
||||
|
||||
// 递归查找
|
||||
const allTagged = hierarchySystem.findChildrenByTag(parent, TAG_ENEMY, true);
|
||||
```
|
||||
|
||||
#### forEachChild
|
||||
|
||||
遍历子实体:
|
||||
|
||||
```typescript
|
||||
// 遍历直接子级
|
||||
hierarchySystem.forEachChild(parent, (child) => {
|
||||
console.log(child.name);
|
||||
});
|
||||
|
||||
// 递归遍历所有后代
|
||||
hierarchySystem.forEachChild(parent, (child) => {
|
||||
console.log(child.name);
|
||||
}, true);
|
||||
```
|
||||
|
||||
### 层级状态
|
||||
|
||||
#### isActiveInHierarchy
|
||||
|
||||
检查实体在层级中是否激活(考虑所有祖先的激活状态):
|
||||
|
||||
```typescript
|
||||
// 如果 parent.active = false,即使 child.active = true
|
||||
// isActiveInHierarchy(child) 也会返回 false
|
||||
const activeInHierarchy = hierarchySystem.isActiveInHierarchy(child);
|
||||
```
|
||||
|
||||
#### getDepth
|
||||
|
||||
获取实体在层级中的深度(根实体深度为 0):
|
||||
|
||||
```typescript
|
||||
const depth = hierarchySystem.getDepth(entity);
|
||||
```
|
||||
|
||||
### 扁平化层级(用于 UI 渲染)
|
||||
|
||||
```typescript
|
||||
// 用于实现可展开/折叠的层级树视图
|
||||
const expandedIds = new Set([parent.id]);
|
||||
|
||||
const flatNodes = hierarchySystem.flattenHierarchy(expandedIds);
|
||||
// 返回 [{ entity, depth, bHasChildren, bIsExpanded }, ...]
|
||||
```
|
||||
|
||||
## 完整示例
|
||||
|
||||
### 创建游戏角色层级
|
||||
|
||||
```typescript
|
||||
import {
|
||||
Scene,
|
||||
HierarchySystem,
|
||||
HierarchyComponent
|
||||
} from '@esengine/ecs-framework';
|
||||
|
||||
class GameScene extends Scene {
|
||||
private hierarchySystem!: HierarchySystem;
|
||||
|
||||
protected initialize(): void {
|
||||
// 添加层级系统
|
||||
this.hierarchySystem = new HierarchySystem();
|
||||
this.addSystem(this.hierarchySystem);
|
||||
|
||||
// 创建角色层级
|
||||
this.createPlayerHierarchy();
|
||||
}
|
||||
|
||||
private createPlayerHierarchy(): void {
|
||||
// 根实体
|
||||
const player = this.createEntity("Player");
|
||||
player.addComponent(new Transform(0, 0));
|
||||
|
||||
// 身体部件
|
||||
const body = this.createEntity("Body");
|
||||
body.addComponent(new Sprite("body.png"));
|
||||
this.hierarchySystem.setParent(body, player);
|
||||
|
||||
// 武器(挂载在身体上)
|
||||
const weapon = this.createEntity("Weapon");
|
||||
weapon.addComponent(new Sprite("sword.png"));
|
||||
this.hierarchySystem.setParent(weapon, body);
|
||||
|
||||
// 特效(挂载在武器上)
|
||||
const effect = this.createEntity("WeaponEffect");
|
||||
effect.addComponent(new ParticleEmitter());
|
||||
this.hierarchySystem.setParent(effect, weapon);
|
||||
|
||||
// 查询层级信息
|
||||
console.log(`Player 层级深度: ${this.hierarchySystem.getDepth(player)}`); // 0
|
||||
console.log(`Weapon 层级深度: ${this.hierarchySystem.getDepth(weapon)}`); // 2
|
||||
console.log(`Effect 层级深度: ${this.hierarchySystem.getDepth(effect)}`); // 3
|
||||
}
|
||||
|
||||
public equipNewWeapon(weaponName: string): void {
|
||||
const body = this.findEntity("Body");
|
||||
const oldWeapon = this.hierarchySystem.findChild(body!, "Weapon");
|
||||
|
||||
if (oldWeapon) {
|
||||
// 移除旧武器的所有子实体
|
||||
this.hierarchySystem.removeAllChildren(oldWeapon);
|
||||
oldWeapon.destroy();
|
||||
}
|
||||
|
||||
// 创建新武器
|
||||
const newWeapon = this.createEntity("Weapon");
|
||||
newWeapon.addComponent(new Sprite(`${weaponName}.png`));
|
||||
this.hierarchySystem.setParent(newWeapon, body!);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 层级变换系统
|
||||
|
||||
结合 Transform 组件实现层级变换:
|
||||
|
||||
```typescript
|
||||
import { EntitySystem, Matcher, HierarchySystem, HierarchyComponent } from '@esengine/ecs-framework';
|
||||
|
||||
class HierarchyTransformSystem extends EntitySystem {
|
||||
private hierarchySystem!: HierarchySystem;
|
||||
|
||||
constructor() {
|
||||
super(Matcher.empty().all(Transform, HierarchyComponent));
|
||||
}
|
||||
|
||||
public onAddedToScene(): void {
|
||||
// 获取层级系统引用
|
||||
this.hierarchySystem = this.scene!.getEntityProcessor(HierarchySystem)!;
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 按深度排序,确保父级先更新
|
||||
const sorted = [...entities].sort((a, b) => {
|
||||
return this.hierarchySystem.getDepth(a) - this.hierarchySystem.getDepth(b);
|
||||
});
|
||||
|
||||
for (const entity of sorted) {
|
||||
const transform = entity.getComponent(Transform)!;
|
||||
const parent = this.hierarchySystem.getParent(entity);
|
||||
|
||||
if (parent) {
|
||||
const parentTransform = parent.getComponent(Transform);
|
||||
if (parentTransform) {
|
||||
// 计算世界坐标
|
||||
transform.worldX = parentTransform.worldX + transform.localX;
|
||||
transform.worldY = parentTransform.worldY + transform.localY;
|
||||
}
|
||||
} else {
|
||||
// 根实体,本地坐标即世界坐标
|
||||
transform.worldX = transform.localX;
|
||||
transform.worldY = transform.localY;
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 性能优化
|
||||
|
||||
### 缓存机制
|
||||
|
||||
`HierarchySystem` 内置了缓存机制:
|
||||
|
||||
- `depth` 和 `bActiveInHierarchy` 由系统自动维护
|
||||
- 使用 `bCacheDirty` 标记优化更新
|
||||
- 层级变化时自动标记所有子级缓存为脏
|
||||
|
||||
### 最佳实践
|
||||
|
||||
1. **避免深层嵌套**:系统限制最大深度为 32 层
|
||||
2. **批量操作**:构建复杂层级时,尽量一次性设置好所有父子关系
|
||||
3. **按需添加**:只有真正需要层级关系的实体才添加 `HierarchyComponent`
|
||||
4. **缓存系统引用**:避免每次调用都获取 `HierarchySystem`
|
||||
|
||||
```typescript
|
||||
// 好的做法
|
||||
class MySystem extends EntitySystem {
|
||||
private hierarchySystem!: HierarchySystem;
|
||||
|
||||
onAddedToScene() {
|
||||
this.hierarchySystem = this.scene!.getEntityProcessor(HierarchySystem)!;
|
||||
}
|
||||
|
||||
process() {
|
||||
// 使用缓存的引用
|
||||
const parent = this.hierarchySystem.getParent(entity);
|
||||
}
|
||||
}
|
||||
|
||||
// 避免的做法
|
||||
process() {
|
||||
// 每次都获取,性能较差
|
||||
const system = this.scene!.getEntityProcessor(HierarchySystem);
|
||||
}
|
||||
```
|
||||
|
||||
## 迁移指南
|
||||
|
||||
如果你之前使用的是旧版 Entity 内置的层级 API,请参考以下迁移指南:
|
||||
|
||||
| 旧 API (已移除) | 新 API |
|
||||
|----------------|--------|
|
||||
| `entity.parent` | `hierarchySystem.getParent(entity)` |
|
||||
| `entity.children` | `hierarchySystem.getChildren(entity)` |
|
||||
| `entity.addChild(child)` | `hierarchySystem.setParent(child, entity)` |
|
||||
| `entity.removeChild(child)` | `hierarchySystem.removeChild(entity, child)` |
|
||||
| `entity.findChild(name)` | `hierarchySystem.findChild(entity, name)` |
|
||||
| `entity.activeInHierarchy` | `hierarchySystem.isActiveInHierarchy(entity)` |
|
||||
|
||||
### 迁移示例
|
||||
|
||||
```typescript
|
||||
// 旧代码
|
||||
const parent = scene.createEntity("Parent");
|
||||
const child = scene.createEntity("Child");
|
||||
parent.addChild(child);
|
||||
const found = parent.findChild("Child");
|
||||
|
||||
// 新代码
|
||||
const hierarchySystem = scene.getEntityProcessor(HierarchySystem);
|
||||
|
||||
const parent = scene.createEntity("Parent");
|
||||
const child = scene.createEntity("Child");
|
||||
hierarchySystem.setParent(child, parent);
|
||||
const found = hierarchySystem.findChild(parent, "Child");
|
||||
```
|
||||
|
||||

# 日志系统
|
||||
|
||||
ECS 框架提供了功能强大的分级日志系统,支持多种日志级别、颜色输出、自定义前缀和灵活的配置选项。日志系统可以帮助开发者调试代码和监控应用运行状态。
|
||||
|
||||
## 基本概念
|
||||
|
||||
日志系统包含以下核心概念:
|
||||
- **日志级别**:Debug < Info < Warn < Error < Fatal < None
|
||||
- **日志器**:具名的日志输出器,每个模块可以有自己的日志器
|
||||
- **日志管理器**:全局管理所有日志器的单例
|
||||
- **颜色配置**:支持控制台颜色输出
|
||||
|
||||
## 日志级别
|
||||
|
||||
```typescript
|
||||
import { LogLevel } from '@esengine/ecs-framework';
|
||||
|
||||
// 日志级别从低到高
|
||||
LogLevel.Debug // 0 - 调试信息
|
||||
LogLevel.Info // 1 - 一般信息
|
||||
LogLevel.Warn // 2 - 警告信息
|
||||
LogLevel.Error // 3 - 错误信息
|
||||
LogLevel.Fatal // 4 - 致命错误
|
||||
LogLevel.None // 5 - 不输出任何日志
|
||||
```
|
||||
|
||||
## 基本使用
|
||||
|
||||
### 使用默认日志器
|
||||
|
||||
```typescript
|
||||
import { Logger } from '@esengine/ecs-framework';
|
||||
|
||||
class GameSystem extends EntitySystem {
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 输出不同级别的日志
|
||||
Logger.debug('处理实体数量:', entities.length);
|
||||
Logger.info('系统正常运行');
|
||||
Logger.warn('检测到性能问题');
|
||||
Logger.error('处理过程中发生错误', new Error('示例错误'));
|
||||
Logger.fatal('致命错误,系统即将停止');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 创建命名日志器
|
||||
|
||||
```typescript
|
||||
import { createLogger } from '@esengine/ecs-framework';
|
||||
|
||||
class MovementSystem extends EntitySystem {
|
||||
private logger = createLogger('MovementSystem');
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
this.logger.info(`处理 ${entities.length} 个移动实体`);
|
||||
|
||||
for (const entity of entities) {
|
||||
const position = entity.getComponent(Position);
|
||||
const velocity = entity.getComponent(Velocity);
|
||||
|
||||
if (position && velocity) {
|
||||
position.x += velocity.dx * Time.deltaTime;
|
||||
position.y += velocity.dy * Time.deltaTime;
|
||||
|
||||
this.logger.debug(`实体 ${entity.id} 移动到位置 (${position.x}, ${position.y})`);
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
protected onAdded(entity: Entity): void {
|
||||
this.logger.info(`实体 ${entity.name} 加入移动系统`);
|
||||
}
|
||||
|
||||
protected onRemoved(entity: Entity): void {
|
||||
this.logger.warn(`实体 ${entity.name} 离开移动系统`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 系统内置日志器
|
||||
|
||||
框架的各个系统都有自己的日志器:
|
||||
|
||||
```typescript
|
||||
// 框架内部使用示例
|
||||
class Scene {
|
||||
private static readonly _logger = createLogger('Scene');
|
||||
|
||||
public addSystem(system: EntitySystem): void {
|
||||
Scene._logger.info(`添加系统: ${system.systemName}`);
|
||||
// 系统添加逻辑
|
||||
}
|
||||
|
||||
public removeSystem(system: EntitySystem): void {
|
||||
Scene._logger.warn(`移除系统: ${system.systemName}`);
|
||||
// 系统移除逻辑
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 日志配置
|
||||
|
||||
### 设置全局日志级别
|
||||
|
||||
```typescript
|
||||
import { setGlobalLogLevel, LogLevel } from '@esengine/ecs-framework';
|
||||
|
||||
// 在开发环境显示所有日志
|
||||
setGlobalLogLevel(LogLevel.Debug);
|
||||
|
||||
// 在生产环境只显示警告及以上级别
|
||||
setGlobalLogLevel(LogLevel.Warn);
|
||||
|
||||
// 完全禁用日志输出
|
||||
setGlobalLogLevel(LogLevel.None);
|
||||
```
|
||||
|
||||
### 创建自定义配置的日志器
|
||||
|
||||
```typescript
|
||||
import { ConsoleLogger, LogLevel } from '@esengine/ecs-framework';
|
||||
|
||||
class CustomLoggerExample {
|
||||
private debugLogger: ConsoleLogger;
|
||||
private productionLogger: ConsoleLogger;
|
||||
|
||||
constructor() {
|
||||
// 开发环境日志器
|
||||
this.debugLogger = new ConsoleLogger({
|
||||
level: LogLevel.Debug,
|
||||
enableTimestamp: true,
|
||||
enableColors: true,
|
||||
prefix: 'DEV'
|
||||
});
|
||||
|
||||
// 生产环境日志器
|
||||
this.productionLogger = new ConsoleLogger({
|
||||
level: LogLevel.Error,
|
||||
enableTimestamp: true,
|
||||
enableColors: false,
|
||||
prefix: 'PROD'
|
||||
});
|
||||
}
|
||||
|
||||
public logDevelopmentInfo(): void {
|
||||
this.debugLogger.debug('这是调试信息');
|
||||
this.debugLogger.info('开发环境信息');
|
||||
}
|
||||
|
||||
public logProductionError(): void {
|
||||
this.productionLogger.error('生产环境错误');
|
||||
this.productionLogger.fatal('致命错误');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 颜色配置
|
||||
|
||||
### 使用预定义颜色
|
||||
|
||||
```typescript
|
||||
import { Colors, setLoggerColors } from '@esengine/ecs-framework';
|
||||
|
||||
// 自定义颜色方案
|
||||
setLoggerColors({
|
||||
debug: Colors.BRIGHT_BLACK,
|
||||
info: Colors.BLUE,
|
||||
warn: Colors.YELLOW,
|
||||
error: Colors.RED,
|
||||
fatal: Colors.BRIGHT_RED
|
||||
});
|
||||
```
|
||||
|
||||
### 完整颜色示例
|
||||
|
||||
```typescript
|
||||
import { LoggerManager, Colors, LogLevel } from '@esengine/ecs-framework';
|
||||
|
||||
class ColorLoggerDemo {
|
||||
private logger = createLogger('ColorDemo');
|
||||
|
||||
constructor() {
|
||||
// 设置自定义颜色
|
||||
const manager = LoggerManager.getInstance();
|
||||
manager.setGlobalColors({
|
||||
debug: Colors.CYAN,
|
||||
info: Colors.GREEN,
|
||||
warn: Colors.YELLOW,
|
||||
error: Colors.RED,
|
||||
fatal: `${Colors.BOLD}${Colors.BRIGHT_RED}`
|
||||
});
|
||||
}
|
||||
|
||||
public demonstrateColors(): void {
|
||||
this.logger.debug('这是蓝绿色的调试信息');
|
||||
this.logger.info('这是绿色的信息');
|
||||
this.logger.warn('这是黄色的警告');
|
||||
this.logger.error('这是红色的错误');
|
||||
this.logger.fatal('这是加粗的亮红色致命错误');
|
||||
}
|
||||
|
||||
public resetToDefaults(): void {
|
||||
// 重置为默认颜色
|
||||
LoggerManager.getInstance().resetColors();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 高级功能
|
||||
|
||||
### 分层日志器
|
||||
|
||||
```typescript
|
||||
import { LoggerManager } from '@esengine/ecs-framework';
|
||||
|
||||
class HierarchicalLoggingExample {
|
||||
private systemLogger = createLogger('GameSystems');
|
||||
private movementLogger: ILogger;
|
||||
private renderLogger: ILogger;
|
||||
|
||||
constructor() {
|
||||
const manager = LoggerManager.getInstance();
|
||||
|
||||
// 创建子日志器
|
||||
this.movementLogger = manager.createChildLogger('GameSystems', 'Movement');
|
||||
this.renderLogger = manager.createChildLogger('GameSystems', 'Render');
|
||||
}
|
||||
|
||||
public demonstrateHierarchy(): void {
|
||||
this.systemLogger.info('游戏系统启动');
|
||||
|
||||
// 子日志器会显示完整路径:[GameSystems.Movement]
|
||||
this.movementLogger.debug('移动系统初始化');
|
||||
|
||||
// 子日志器会显示完整路径:[GameSystems.Render]
|
||||
this.renderLogger.info('渲染系统启动');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 集成第三方日志库
|
||||
|
||||
通过 `setLoggerFactory` 可以将业务代码中的日志器替换为第三方日志库(如 winston、pino、nestjs Logger 等)。
|
||||
|
||||
**说明**: 目前框架内部日志仍使用 ConsoleLogger,自定义日志器仅影响业务代码(如 EntitySystem)。
|
||||
|
||||
#### 基本用法
|
||||
|
||||
```typescript
|
||||
import { setLoggerFactory } from '@esengine/ecs-framework';
|
||||
|
||||
setLoggerFactory((name?: string) => {
|
||||
// 返回实现 ILogger 接口的日志器实例
|
||||
return yourLogger;
|
||||
});
|
||||
```
|
||||
|
||||
#### 使用示例
|
||||
|
||||
```typescript
|
||||
// 集成 Winston
|
||||
setLoggerFactory((name?: string) => winston.createLogger({ /* ... */ }));
|
||||
|
||||
// 集成 Pino
|
||||
setLoggerFactory((name?: string) => pino({ name }));
|
||||
|
||||
// 集成 NestJS Logger
|
||||
setLoggerFactory((name?: string) => new Logger(name));
|
||||
```
|
||||
|
||||
#### EntitySystem 中的使用
|
||||
|
||||
EntitySystem 会自动使用类名创建日志器:
|
||||
|
||||
```typescript
|
||||
class PlayerMovementSystem extends EntitySystem {
|
||||
// this.logger 自动使用 'PlayerMovementSystem' 作为名称
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
this.logger.info(`处理 ${entities.length} 个玩家实体`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 自定义输出
|
||||
|
||||
```typescript
|
||||
import { ConsoleLogger, LogLevel } from '@esengine/ecs-framework';
|
||||
|
||||
class CustomOutputLogger {
|
||||
private fileLogger: ConsoleLogger;
|
||||
private networkLogger: ConsoleLogger;
|
||||
|
||||
constructor() {
|
||||
// 输出到文件的日志器(模拟)
|
||||
this.fileLogger = new ConsoleLogger({
|
||||
level: LogLevel.Info,
|
||||
output: (level: LogLevel, message: string) => {
|
||||
this.writeToFile(LogLevel[level], message);
|
||||
}
|
||||
});
|
||||
|
||||
// 发送到网络的日志器(模拟)
|
||||
this.networkLogger = new ConsoleLogger({
|
||||
level: LogLevel.Error,
|
||||
output: (level: LogLevel, message: string) => {
|
||||
this.sendToServer(LogLevel[level], message);
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
private writeToFile(level: string, message: string): void {
|
||||
// 模拟文件写入
|
||||
console.log(`[FILE] ${level}: ${message}`);
|
||||
}
|
||||
|
||||
private sendToServer(level: string, message: string): void {
|
||||
// 模拟网络发送
|
||||
console.log(`[NETWORK] ${level}: ${message}`);
|
||||
}
|
||||
|
||||
public logToFile(message: string): void {
|
||||
this.fileLogger.info(message);
|
||||
}
|
||||
|
||||
public logCriticalError(error: Error): void {
|
||||
this.networkLogger.error('Critical error occurred', error);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 实际应用示例
|
||||
|
||||
### 游戏系统日志
|
||||
|
||||
```typescript
|
||||
class GameWithLogging {
|
||||
private gameLogger = createLogger('Game');
|
||||
private performanceLogger = createLogger('Performance');
|
||||
private networkLogger = createLogger('Network');
|
||||
|
||||
constructor() {
|
||||
// 在开发环境启用详细日志
|
||||
if (process.env.NODE_ENV === 'development') {
|
||||
setGlobalLogLevel(LogLevel.Debug);
|
||||
} else {
|
||||
setGlobalLogLevel(LogLevel.Warn);
|
||||
}
|
||||
}
|
||||
|
||||
public startGame(): void {
|
||||
this.gameLogger.info('游戏开始启动');
|
||||
|
||||
try {
|
||||
this.initializeSystems();
|
||||
this.loadResources();
|
||||
this.startGameLoop();
|
||||
|
||||
this.gameLogger.info('游戏启动成功');
|
||||
} catch (error) {
|
||||
this.gameLogger.fatal('游戏启动失败', error);
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
private initializeSystems(): void {
|
||||

this.networkLogger.error('数据同步错误', data);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 错误追踪和调试
|
||||
|
||||
```typescript
|
||||
class ErrorTrackingSystem extends EntitySystem {
|
||||
private logger = createLogger('ErrorTracker');
|
||||
private errorCounts = new Map<string, number>();
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
try {
|
||||
this.processEntity(entity);
|
||||
} catch (error) {
|
||||
this.handleError(entity, error as Error);
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
private processEntity(entity: Entity): void {
|
||||
// 模拟可能出错的实体处理
|
||||
if (Math.random() < 0.01) { // 1% 概率出错
|
||||
throw new Error(`Processing error for entity ${entity.id}`);
|
||||
}
|
||||
|
||||
this.logger.debug(`成功处理实体 ${entity.id}`);
|
||||
}
|
||||
|
||||
private handleError(entity: Entity, error: Error): void {
|
||||
const errorKey = error.message;
|
||||
const count = this.errorCounts.get(errorKey) || 0;
|
||||
this.errorCounts.set(errorKey, count + 1);
|
||||
|
||||
this.logger.error(
|
||||
`实体 ${entity.id} 处理失败 (第${count + 1}次): ${error.message}`,
|
||||
{
|
||||
entityId: entity.id,
|
||||
entityName: entity.name,
|
||||
componentCount: entity.components.length,
|
||||
errorStack: error.stack
|
||||
}
|
||||
);
|
||||
|
||||
// 如果同一类型错误发生太多次,升级为警告
|
||||
if (count >= 5) {
|
||||
this.logger.warn(`错误 "${errorKey}" 已发生 ${count + 1} 次,可能需要关注`);
|
||||
}
|
||||
|
||||
// 如果错误次数过多,升级为致命错误
|
||||
if (count >= 20) {
|
||||
this.logger.fatal(`错误 "${errorKey}" 发生次数过多,系统可能存在严重问题`);
|
||||
}
|
||||
}
|
||||
|
||||
public getErrorSummary(): void {
|
||||
this.logger.info('=== 错误统计 ===');
|
||||
for (const [error, count] of this.errorCounts) {
|
||||
this.logger.info(`${error}: ${count} 次`);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 合理的日志级别选择
|
||||
|
||||
```typescript
|
||||
class LoggingBestPractices {
|
||||
private logger = createLogger('BestPractices');
|
||||
|
||||
public demonstrateLogLevels(): void {
|
||||
// ✅ Debug - 详细的调试信息
|
||||
this.logger.debug('变量值', { x: 10, y: 20 });
|
||||
|
||||
// ✅ Info - 重要的状态变化
|
||||
this.logger.info('系统启动完成');
|
||||
|
||||
// ✅ Warn - 异常但不致命的情况
|
||||
this.logger.warn('资源未找到,使用默认值');
|
||||
|
||||
// ✅ Error - 错误但程序可以继续
|
||||
this.logger.error('保存失败,将重试', new Error('Network timeout'));
|
||||
|
||||
// ✅ Fatal - 致命错误,程序无法继续
|
||||
this.logger.fatal('内存不足,程序即将退出');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 结构化日志数据
|
||||
|
||||
```typescript
|
||||
class StructuredLogging {
|
||||
private logger = createLogger('Structured');
|
||||
|
||||
public logWithStructuredData(): void {
|
||||
// ✅ 提供结构化的上下文信息
|
||||
this.logger.info('用户操作', {
|
||||
userId: 12345,
|
||||
action: 'move',
|
||||
position: { x: 100, y: 200 },
|
||||
timestamp: Date.now()
|
||||
});
|
||||
|
||||
// ✅ 包含相关的错误上下文
|
||||
this.logger.error('数据库查询失败', {
|
||||
query: 'SELECT * FROM users',
|
||||
parameters: { id: 123 },
|
||||
connectionId: 'conn_456',
|
||||
retryCount: 3
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 避免日志性能问题
|
||||
|
||||
```typescript
|
||||
class PerformanceConsciousLogging {
|
||||
private logger = createLogger('Performance');
|
||||
|
||||
public efficientLogging(): void {
|
||||
// ✅ 检查日志级别避免不必要的计算
|
||||
if (this.logger.debug) {
|
||||
const expensiveData = this.calculateExpensiveDebugInfo();
|
||||
this.logger.debug('详细调试信息', expensiveData);
|
||||
}
|
||||
|
||||
// ❌ 避免:总是计算昂贵的日志数据
|
||||
// this.logger.debug('调试信息', this.calculateExpensiveDebugInfo());
|
||||
}
|
||||
|
||||
private calculateExpensiveDebugInfo(): any {
|
||||
// 模拟昂贵的计算
|
||||
return { /* 复杂的调试数据 */ };
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 日志配置管理
|
||||
|
||||
```typescript
|
||||
class LoggingConfiguration {
|
||||
public static setupLogging(): void {
|
||||
// 根据环境配置日志级别
|
||||
const isDevelopment = process.env.NODE_ENV === 'development';
|
||||
const isProduction = process.env.NODE_ENV === 'production';
|
||||
|
||||
if (isDevelopment) {
|
||||
setGlobalLogLevel(LogLevel.Debug);
|
||||
setLoggerColors({
|
||||
debug: Colors.CYAN,
|
||||
info: Colors.GREEN,
|
||||
warn: Colors.YELLOW,
|
||||
error: Colors.RED,
|
||||
fatal: Colors.BRIGHT_RED
|
||||
});
|
||||
} else if (isProduction) {
|
||||
setGlobalLogLevel(LogLevel.Warn);
|
||||
// 生产环境禁用颜色
|
||||
LoggerManager.getInstance().resetColors();
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// 在应用启动时配置日志
|
||||
LoggingConfiguration.setupLogging();
|
||||
```
|
||||
|
||||
日志系统是调试和监控应用的重要工具,正确使用日志系统能大大提高开发效率和问题排查能力。

## 核心接口
|
||||
|
||||
### IPlatformAdapter
|
||||
|
||||
```typescript
|
||||
export interface IPlatformAdapter {
|
||||
readonly name: string;
|
||||
readonly version?: string;
|
||||
|
||||
isWorkerSupported(): boolean;
|
||||
isSharedArrayBufferSupported(): boolean;
|
||||
getHardwareConcurrency(): number;
|
||||
createWorker(script: string, options?: WorkerCreationOptions): PlatformWorker;
|
||||
createSharedArrayBuffer(length: number): SharedArrayBuffer | null;
|
||||
getHighResTimestamp(): number;
|
||||
getPlatformConfig(): PlatformConfig;
|
||||
getPlatformConfigAsync?(): Promise<PlatformConfig>;
|
||||
}
|
||||
```
|
||||
|
||||
### PlatformWorker 接口
|
||||
|
||||
```typescript
|
||||
export interface PlatformWorker {
|
||||
postMessage(message: any, transfer?: Transferable[]): void;
|
||||
onMessage(handler: (event: { data: any }) => void): void;
|
||||
onError(handler: (error: ErrorEvent) => void): void;
|
||||
terminate(): void;
|
||||
readonly state: 'running' | 'terminated';
|
||||
}
|
||||
```
|
||||
|
||||
## 使用方法
|
||||
|
||||
### 1. 选择合适的平台适配器
|
||||
|
||||
根据你的运行环境选择对应的适配器:
|
||||
|
||||
```typescript
|
||||
import { PlatformManager } from '@esengine/ecs-framework';
|
||||
|
||||
// 浏览器环境
|
||||
if (typeof window !== 'undefined') {
|
||||
const { BrowserAdapter } = await import('./platform/BrowserAdapter');
|
||||
PlatformManager.getInstance().registerAdapter(new BrowserAdapter());
|
||||
}
|
||||
|
||||
// 微信小游戏环境
|
||||
else if (typeof wx !== 'undefined') {
|
||||
const { WeChatMiniGameAdapter } = await import('./platform/WeChatMiniGameAdapter');
|
||||
PlatformManager.getInstance().registerAdapter(new WeChatMiniGameAdapter());
|
||||
}
|
||||
|
||||
// Node.js环境
|
||||
else if (typeof process !== 'undefined' && process.versions?.node) {
|
||||
const { NodeAdapter } = await import('./platform/NodeAdapter');
|
||||
PlatformManager.getInstance().registerAdapter(new NodeAdapter());
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 检查适配器状态
|
||||
|
||||
```typescript
|
||||
const manager = PlatformManager.getInstance();
|
||||
|
||||
// 检查是否已注册适配器
|
||||
if (manager.hasAdapter()) {
|
||||
const adapter = manager.getAdapter();
|
||||
console.log('当前平台:', adapter.name);
|
||||
console.log('平台版本:', adapter.version);
|
||||
|
||||
// 检查功能支持
|
||||
console.log('Worker支持:', manager.supportsFeature('worker'));
|
||||
console.log('SharedArrayBuffer支持:', manager.supportsFeature('shared-array-buffer'));
|
||||
}
|
||||
```
|
||||
|
||||
## 创建自定义适配器
|
||||
|
||||
如果现有的平台适配器不能满足你的需求,你可以创建自定义适配器:
|
||||
|
||||
### 1. 实现接口
|
||||
|
||||
```typescript
|
||||
import type { IPlatformAdapter, PlatformWorker, WorkerCreationOptions, PlatformConfig } from '@esengine/ecs-framework';
|
||||
|
||||
export class CustomAdapter implements IPlatformAdapter {
|
||||
public readonly name = 'custom';
|
||||
public readonly version = '1.0.0';
|
||||
|
||||
public isWorkerSupported(): boolean {
|
||||
// 实现你的 Worker 支持检查逻辑
|
||||
return false;
|
||||
}
|
||||
|
||||
public isSharedArrayBufferSupported(): boolean {
|
||||
// 实现你的 SharedArrayBuffer 支持检查逻辑
|
||||
return false;
|
||||
}
|
||||
|
||||
public getHardwareConcurrency(): number {
|
||||
// 返回你的平台的并发数
|
||||
return 1;
|
||||
}
|
||||
|
||||
public createWorker(script: string, options?: WorkerCreationOptions): PlatformWorker {
|
||||
throw new Error('Worker not supported on this platform');
|
||||
}
|
||||
|
||||
public createSharedArrayBuffer(length: number): SharedArrayBuffer | null {
|
||||
return null;
|
||||
}
|
||||
|
||||
public getHighResTimestamp(): number {
|
||||
return Date.now();
|
||||
}
|
||||
|
||||
public getPlatformConfig(): PlatformConfig {
|
||||
return {
|
||||
maxWorkerCount: 1,
|
||||
supportsModuleWorker: false,
|
||||
supportsTransferableObjects: false,
|
||||
limitations: {
|
||||
workerNotSupported: true
|
||||
}
|
||||
};
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 注册自定义适配器
|
||||
|
||||
```typescript
|
||||
import { PlatformManager } from '@esengine/ecs-framework';
|
||||
import { CustomAdapter } from './CustomAdapter';
|
||||
|
||||
const customAdapter = new CustomAdapter();
|
||||
PlatformManager.getInstance().registerAdapter(customAdapter);
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 平台检测顺序
|
||||
|
||||
建议按照以下顺序检测和注册平台适配器:
|
||||
|
||||
```typescript
|
||||
async function initializePlatform() {
|
||||
const manager = PlatformManager.getInstance();
|
||||
|
||||
try {
|
||||
// 1. 微信小游戏 (优先级最高,环境特征最明显)
|
||||
if (typeof wx !== 'undefined' && wx.getSystemInfoSync) {
|
||||
const { WeChatMiniGameAdapter } = await import('./platform/WeChatMiniGameAdapter');
|
||||
manager.registerAdapter(new WeChatMiniGameAdapter());
|
||||
return;
|
||||
}
|
||||
|
||||
// 2. Node.js 环境
|
||||
if (typeof process !== 'undefined' && process.versions?.node) {
|
||||
const { NodeAdapter } = await import('./platform/NodeAdapter');
|
||||
manager.registerAdapter(new NodeAdapter());
|
||||
return;
|
||||
}
|
||||
|
||||
// 3. 浏览器环境 (最后检测,覆盖面最广)
|
||||
if (typeof window !== 'undefined' && typeof document !== 'undefined') {
|
||||
const { BrowserAdapter } = await import('./platform/BrowserAdapter');
|
||||
manager.registerAdapter(new BrowserAdapter());
|
||||
return;
|
||||
}
|
||||
|
||||
// 4. 未知环境,使用默认适配器
|
||||
console.warn('未识别的平台环境,使用默认适配器');
|
||||
manager.registerAdapter(new CustomAdapter());
|
||||
|
||||
} catch (error) {
|
||||
console.error('平台适配器初始化失败:', error);
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 功能降级处理
|
||||
|
||||
```typescript
|
||||
function createWorkerSystem() {
|
||||
const manager = PlatformManager.getInstance();
|
||||
|
||||
if (!manager.hasAdapter()) {
|
||||
throw new Error('未注册平台适配器');
|
||||
}
|
||||
|
||||
const config: WorkerSystemConfig = {
|
||||
enableWorker: manager.supportsFeature('worker'),
|
||||
workerCount: manager.supportsFeature('worker') ?
|
||||
manager.getAdapter().getHardwareConcurrency() : 1,
|
||||
useSharedArrayBuffer: manager.supportsFeature('shared-array-buffer')
|
||||
};
|
||||
|
||||
// 如果不支持Worker,自动降级到同步处理
|
||||
if (!config.enableWorker) {
|
||||
console.info('当前平台不支持Worker,使用同步处理模式');
|
||||
}
|
||||
|
||||
return new PhysicsSystem(config);
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 错误处理
|
||||
|
||||
```typescript
|
||||
try {
|
||||
await initializePlatform();
|
||||
|
||||
// 验证适配器功能
|
||||
const manager = PlatformManager.getInstance();
|
||||
const adapter = manager.getAdapter();
|
||||
|
||||
console.log(`平台适配器初始化成功: ${adapter.name} v${adapter.version}`);
|
||||
|
||||
} catch (error) {
|
||||
console.error('平台初始化失败:', error);
|
||||
|
||||
// 提供降级方案
|
||||
const fallbackAdapter = new CustomAdapter();
|
||||
PlatformManager.getInstance().registerAdapter(fallbackAdapter);
|
||||
|
||||
console.warn('使用降级适配器继续运行');
|
||||
}
|
||||
```

|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 使用方法
|
||||
|
||||
### 1. 复制代码
|
||||
|
||||
将上述代码复制到你的项目中,例如 `src/platform/BrowserAdapter.ts`。
|
||||
|
||||
### 2. 注册适配器
|
||||
|
||||
```typescript
|
||||
import { PlatformManager } from '@esengine/ecs-framework';
|
||||
import { BrowserAdapter } from './platform/BrowserAdapter';
|
||||
|
||||
// 创建并注册浏览器适配器
|
||||
const browserAdapter = new BrowserAdapter();
|
||||
PlatformManager.registerAdapter(browserAdapter);
|
||||
|
||||
// 框架会自动检测和使用合适的适配器
|
||||
```
|
||||
|
||||
### 3. 使用 WorkerEntitySystem
|
||||
|
||||
浏览器适配器与 WorkerEntitySystem 配合使用,框架会自动处理 Worker 脚本的创建:
|
||||
|
||||
```typescript
|
||||
import { WorkerEntitySystem, Matcher } from '@esengine/ecs-framework';
|
||||
|
||||
class PhysicsSystem extends WorkerEntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(Transform, Velocity), {
|
||||
enableWorker: true,
|
||||
workerCount: navigator.hardwareConcurrency || 4,
|
||||
useSharedArrayBuffer: true,
|
||||
systemConfig: { gravity: 9.8 }
|
||||
});
|
||||
}
|
||||
|
||||
protected getDefaultEntityDataSize(): number {
|
||||
return 6; // x, y, vx, vy, mass, radius
|
||||
}
|
||||
|
||||
protected extractEntityData(entity: Entity): PhysicsData {
|
||||
const transform = entity.getComponent(Transform);
|
||||
const velocity = entity.getComponent(Velocity);
|
||||
return {
|
||||
x: transform.x,
|
||||
y: transform.y,
|
||||
vx: velocity.x,
|
||||
vy: velocity.y,
|
||||
mass: 1,
|
||||
radius: 10
|
||||
};
|
||||
}
|
||||
|
||||
// 这个函数会被自动序列化并在Worker中执行
|
||||
protected workerProcess(entities, deltaTime, config) {
|
||||
return entities.map(entity => {
|
||||
// 应用重力
|
||||
entity.vy += config.gravity * deltaTime;
|
||||
|
||||
// 更新位置
|
||||
entity.x += entity.vx * deltaTime;
|
||||
entity.y += entity.vy * deltaTime;
|
||||
|
||||
return entity;
|
||||
});
|
||||
}
|
||||
|
||||
protected applyResult(entity: Entity, result: PhysicsData): void {
|
||||
const transform = entity.getComponent(Transform);
|
||||
const velocity = entity.getComponent(Velocity);
|
||||
|
||||
transform.x = result.x;
|
||||
transform.y = result.y;
|
||||
velocity.x = result.vx;
|
||||
velocity.y = result.vy;
|
||||
}
|
||||
}
|
||||
|
||||
interface PhysicsData {
|
||||
x: number;
|
||||
y: number;
|
||||
vx: number;
|
||||
vy: number;
|
||||
mass: number;
|
||||
radius: number;
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 验证适配器工作状态
|
||||
|
||||
```typescript
|
||||
// 验证适配器是否正常工作
|
||||
const adapter = new BrowserAdapter();
|
||||
console.log('适配器名称:', adapter.name);
|
||||
console.log('浏览器版本:', adapter.version);
|
||||
console.log('Worker支持:', adapter.isWorkerSupported());
|
||||
console.log('SharedArrayBuffer支持:', adapter.isSharedArrayBufferSupported());
|
||||
console.log('CPU核心数:', adapter.getHardwareConcurrency());
|
||||
```
|
||||
|
||||
## 重要注意事项
|
||||
|
||||
### SharedArrayBuffer 支持
|
||||
|
||||
SharedArrayBuffer 需要特殊的安全配置:
|
||||
|
||||
1. **HTTPS**: 必须在安全上下文中使用
|
||||
2. **COOP/COEP 头部**: 需要设置正确的跨域隔离头部
|
||||
|
||||
```html
|
||||
<!-- 在 HTML 中设置 -->
|
||||
<meta http-equiv="Cross-Origin-Opener-Policy" content="same-origin">
|
||||
<meta http-equiv="Cross-Origin-Embedder-Policy" content="require-corp">
|
||||
```
|
||||
|
||||
或在服务器配置中设置:
|
||||
|
||||
```
|
||||
Cross-Origin-Opener-Policy: same-origin
|
||||
Cross-Origin-Embedder-Policy: require-corp
|
||||
```
|
||||
|
||||
### 浏览器兼容性
|
||||
|
||||
- **Worker**: 所有现代浏览器支持
|
||||
- **Module Worker**: Chrome 80+, Firefox 114+
|
||||
- **SharedArrayBuffer**: Chrome 68+, Firefox 79+(需要COOP/COEP)
|
||||
- **Transferable Objects**: 所有现代浏览器支持
|
||||
|
||||
## 性能优化建议
|
||||
|
||||
1. **Worker 池**: 复用 Worker 实例,避免频繁创建和销毁
|
||||
2. **数据传输**: 使用 Transferable Objects 减少数据拷贝
|
||||
3. **SharedArrayBuffer**: 对于大量数据共享,使用 SharedArrayBuffer
|
||||
4. **模块 Worker**: 在支持的浏览器中使用模块 Worker 来更好地组织代码
|
||||
|
||||
## 调试技巧
|
||||
|
||||
```typescript
|
||||
// 检查浏览器支持情况
|
||||
const adapter = new BrowserAdapter();
|
||||
console.log('Worker支持:', adapter.isWorkerSupported());
|
||||
console.log('SharedArrayBuffer支持:', adapter.isSharedArrayBufferSupported());
|
||||
console.log('硬件并发数:', adapter.getHardwareConcurrency());
|
||||
console.log('平台配置:', adapter.getPlatformConfig());
|
||||
```

# Node.js 适配器
|
||||
|
||||
## 概述
|
||||
|
||||
Node.js 平台适配器为 Node.js 服务器环境提供支持,适用于游戏服务器、计算服务器或其他需要 ECS 架构的服务器应用。
|
||||
|
||||
## 特性支持
|
||||
|
||||
- ✅ **Worker**: 支持(通过 `worker_threads` 模块)
|
||||
- ❌ **SharedArrayBuffer**: 支持(Node.js 16.17.0+)
|
||||
- ✅ **Transferable Objects**: 完全支持
|
||||
- ✅ **高精度时间**: 使用 `process.hrtime.bigint()`
|
||||
- ✅ **设备信息**: 完整的系统和进程信息
|
||||
|
||||
## 完整实现
|
||||
|
||||
```typescript
|
||||
import { worker_threads, Worker, isMainThread, parentPort } from 'worker_threads';
|
||||
import * as os from 'os';
|
||||

}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 使用方法
|
||||
|
||||
### 1. 复制代码
|
||||
|
||||
将上述代码复制到你的项目中,例如 `src/platform/NodeAdapter.ts`。
|
||||
|
||||
### 2. 注册适配器
|
||||
|
||||
```typescript
|
||||
import { PlatformManager } from '@esengine/ecs-framework';
|
||||
import { NodeAdapter } from './platform/NodeAdapter';
|
||||
|
||||
// 检查是否在Node.js环境
|
||||
if (typeof process !== 'undefined' && process.versions && process.versions.node) {
|
||||
const nodeAdapter = new NodeAdapter();
|
||||
PlatformManager.getInstance().registerAdapter(nodeAdapter);
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 使用 WorkerEntitySystem
|
||||
|
||||
Node.js 适配器与 WorkerEntitySystem 配合使用,框架会自动处理 Worker 脚本的创建:
|
||||
|
||||
```typescript
|
||||
import { WorkerEntitySystem, Matcher } from '@esengine/ecs-framework';
|
||||
import * as os from 'os';
|
||||
|
||||
class PhysicsSystem extends WorkerEntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(Transform, Velocity), {
|
||||
enableWorker: true,
|
||||
workerCount: os.cpus().length, // 使用所有CPU核心
|
||||
useSharedArrayBuffer: true,
|
||||
systemConfig: { gravity: 9.8 }
|
||||
});
|
||||
}
|
||||
|
||||
protected getDefaultEntityDataSize(): number {
|
||||
return 6; // x, y, vx, vy, mass, radius
|
||||
}
|
||||
|
||||
protected extractEntityData(entity: Entity): PhysicsData {
|
||||
const transform = entity.getComponent(Transform);
|
||||
const velocity = entity.getComponent(Velocity);
|
||||
return {
|
||||
x: transform.x,
|
||||
y: transform.y,
|
||||
vx: velocity.x,
|
||||
vy: velocity.y,
|
||||
mass: 1,
|
||||
radius: 10
|
||||
};
|
||||
}
|
||||
|
||||
// 这个函数会被自动序列化并在Worker中执行
|
||||
protected workerProcess(entities, deltaTime, config) {
|
||||
return entities.map(entity => {
|
||||
// 应用重力
|
||||
entity.vy += config.gravity * deltaTime;
|
||||
|
||||
// 更新位置
|
||||
entity.x += entity.vx * deltaTime;
|
||||
entity.y += entity.vy * deltaTime;
|
||||
|
||||
return entity;
|
||||
});
|
||||
}
|
||||
|
||||
protected applyResult(entity: Entity, result: PhysicsData): void {
|
||||
const transform = entity.getComponent(Transform);
|
||||
const velocity = entity.getComponent(Velocity);
|
||||
|
||||
transform.x = result.x;
|
||||
transform.y = result.y;
|
||||
velocity.x = result.vx;
|
||||
velocity.y = result.vy;
|
||||
}
|
||||
}
|
||||
|
||||
interface PhysicsData {
|
||||
x: number;
|
||||
y: number;
|
||||
vx: number;
|
||||
vy: number;
|
||||
mass: number;
|
||||
radius: number;
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 获取系统信息
|
||||
|
||||
```typescript
|
||||
const manager = PlatformManager.getInstance();
|
||||
if (manager.hasAdapter()) {
|
||||
const adapter = manager.getAdapter();
|
||||
const deviceInfo = adapter.getDeviceInfo();
|
||||
|
||||
console.log('Node.js版本:', deviceInfo.process?.version);
|
||||
console.log('CPU核心数:', deviceInfo.cpus?.length);
|
||||
console.log('总内存:', Math.round(deviceInfo.totalMemory! / 1024 / 1024), 'MB');
|
||||
console.log('可用内存:', Math.round(deviceInfo.freeMemory! / 1024 / 1024), 'MB');
|
||||
}
|
||||
```
|
||||
|
||||
## 官方文档参考
|
||||
|
||||
Node.js Worker Threads 相关官方文档:
|
||||
|
||||
- [Worker Threads 官方文档](https://nodejs.org/api/worker_threads.html)
|
||||
- [SharedArrayBuffer 支持](https://nodejs.org/api/globals.html#class-sharedarraybuffer)
|
||||
- [OS 模块文档](https://nodejs.org/api/os.html)
|
||||
- [Process 模块文档](https://nodejs.org/api/process.html)
|
||||
|
||||
## 重要注意事项
|
||||
|
||||
### Worker Threads 要求
|
||||
|
||||
- **Node.js版本**: 需要 Node.js 10.5.0+ (建议 12+)
|
||||
- **模块类型**: 支持 CommonJS 和 ES 模块
|
||||
- **线程限制**: 理论上无限制,但建议不超过 CPU 核心数的 2 倍
|
||||
|
||||
### 性能优化建议
|
||||
|
||||
#### 1. Worker 池管理
|
||||
|
||||
```typescript
|
||||
class ServerPhysicsSystem extends WorkerEntitySystem {
|
||||
constructor() {
|
||||
const cpuCount = os.cpus().length;
|
||||
super(Matcher.all(Transform, Velocity), {
|
||||
enableWorker: true,
|
||||
workerCount: Math.min(cpuCount * 2, 16), // 最多16个Worker
|
||||
entitiesPerWorker: 1000, // 每个Worker处理1000个实体
|
||||
useSharedArrayBuffer: true,
|
||||
systemConfig: {
|
||||
gravity: 9.8,
|
||||
timeStep: 1/60
|
||||
}
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 2. 内存管理
|
||||
|
||||
```typescript
|
||||
class MemoryMonitor {
|
||||
public static checkMemoryUsage(): void {
|
||||
const used = process.memoryUsage();
|
||||
|
||||
console.log('内存使用情况:');
|
||||
console.log(` RSS: ${Math.round(used.rss / 1024 / 1024)} MB`);
|
||||
console.log(` Heap Used: ${Math.round(used.heapUsed / 1024 / 1024)} MB`);
|
||||
console.log(` Heap Total: ${Math.round(used.heapTotal / 1024 / 1024)} MB`);
|
||||
console.log(` External: ${Math.round(used.external / 1024 / 1024)} MB`);
|
||||
|
||||
// 内存使用率过高时触发警告
|
||||
if (used.heapUsed > used.heapTotal * 0.9) {
|
||||
console.warn('内存使用率过高,建议优化或重启');
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// 定期检查内存使用
|
||||
setInterval(() => {
|
||||
MemoryMonitor.checkMemoryUsage();
|
||||
}, 30000); // 每30秒检查一次
|
||||
```
|
||||
|
||||
#### 3. 服务器环境优化
|
||||
|
||||
```typescript
|
||||
// 设置进程标题
|
||||
process.title = 'ecs-game-server';
|
||||
|
||||
// 处理未捕获异常
|
||||
process.on('uncaughtException', (error) => {
|
||||
console.error('未捕获异常:', error);
|
||||
process.exit(1);
|
||||
});
|
||||
|
||||
process.on('unhandledRejection', (reason, promise) => {
|
||||
console.error('未处理的Promise拒绝:', reason);
|
||||
});
|
||||
|
||||
// 优雅关闭
|
||||
process.on('SIGTERM', () => {
|
||||
console.log('收到SIGTERM信号,正在关闭服务器...');
|
||||
// 清理资源
|
||||
process.exit(0);
|
||||
});
|
||||
```
|
||||
|
||||
## 调试技巧
|
||||
|
||||
```typescript
|
||||
// 检查Node.js环境支持情况
|
||||
const adapter = new NodeAdapter();
|
||||
console.log('Node.js版本:', adapter.version);
|
||||
console.log('Worker支持:', adapter.isWorkerSupported());
|
||||
console.log('SharedArrayBuffer支持:', adapter.isSharedArrayBufferSupported());
|
||||
console.log('CPU核心数:', adapter.getHardwareConcurrency());
|
||||
|
||||
// 获取详细配置
|
||||
const config = adapter.getPlatformConfig();
|
||||
console.log('平台配置:', JSON.stringify(config, null, 2));
|
||||
|
||||
// 系统资源监控
|
||||
const deviceInfo = adapter.getDeviceInfo();
|
||||
console.log('系统负载:', deviceInfo.loadAverage);
|
||||
console.log('网络接口:', Object.keys(deviceInfo.networkInterfaces!));
|
||||
```

# 微信小游戏适配器
|
||||
|
||||
## 概述
|
||||
|
||||
微信小游戏平台适配器专为微信小游戏环境设计,处理微信小游戏的特殊限制和API。
|
||||
|
||||
## 特性支持
|
||||
|
||||
- ✅ **Worker**: 支持(通过 `wx.createWorker` 创建,需要配置 game.json)
|
||||
- ❌ **SharedArrayBuffer**: 不支持
|
||||
- ❌ **Transferable Objects**: 不支持(只支持可序列化对象)
|
||||
- ✅ **高精度时间**: 使用 `Date.now()` 或 `wx.getPerformance()`
|
||||
- ✅ **设备信息**: 完整的微信小游戏设备信息
|
||||
|
||||

|
||||

|
||||
console.warn('清理Worker脚本文件失败:', error);
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 使用方法
|
||||
|
||||
### 1. 复制代码
|
||||
|
||||
将上述代码复制到你的项目中,例如 `src/platform/WeChatMiniGameAdapter.ts`。
|
||||
|
||||
### 2. 注册适配器
|
||||
|
||||
```typescript
|
||||
import { PlatformManager } from '@esengine/ecs-framework';
|
||||
import { WeChatMiniGameAdapter } from './platform/WeChatMiniGameAdapter';
|
||||
|
||||
// 检查是否在微信小游戏环境
|
||||
if (typeof wx !== 'undefined') {
|
||||
const wechatAdapter = new WeChatMiniGameAdapter();
|
||||
PlatformManager.getInstance().registerAdapter(wechatAdapter);
|
||||
}
|
||||
```
|
||||
|
||||
### 3. WorkerEntitySystem 使用方式
|
||||
|
||||
微信小游戏适配器与 WorkerEntitySystem 配合使用,自动处理 Worker 脚本创建:
|
||||
|
||||
#### 基本使用方式(推荐)
|
||||
|
||||
```typescript
|
||||
import { WorkerEntitySystem, Matcher, Entity } from '@esengine/ecs-framework';
|
||||
|
||||
interface PhysicsData {
|
||||
id: number;
|
||||
x: number;
|
||||
y: number;
|
||||
vx: number;
|
||||
vy: number;
|
||||
mass: number;
|
||||
}
|
||||
|
||||
class PhysicsSystem extends WorkerEntitySystem<PhysicsData> {
|
||||
constructor() {
|
||||
super(Matcher.all(Transform, Velocity), {
|
||||
enableWorker: true,
|
||||
workerCount: 1, // 微信小游戏限制只能创建1个Worker
|
||||
systemConfig: { gravity: 100, friction: 0.95 }
|
||||
});
|
||||
}
|
||||
|
||||
protected getDefaultEntityDataSize(): number {
|
||||
return 6; // id, x, y, vx, vy, mass
|
||||
}
|
||||
|
||||
protected extractEntityData(entity: Entity): PhysicsData {
|
||||
const transform = entity.getComponent(Transform);
|
||||
const velocity = entity.getComponent(Velocity);
|
||||
const physics = entity.getComponent(Physics);
|
||||
|
||||
return {
|
||||
id: entity.id,
|
||||
x: transform.x,
|
||||
y: transform.y,
|
||||
vx: velocity.x,
|
||||
vy: velocity.y,
|
||||
mass: physics.mass
|
||||
};
|
||||
}
|
||||
|
||||
// WorkerEntitySystem 会自动将此函数序列化并写入临时文件
|
||||
protected workerProcess(entities: PhysicsData[], deltaTime: number, config: any): PhysicsData[] {
|
||||
return entities.map(entity => {
|
||||
// 应用重力
|
||||
entity.vy += config.gravity * deltaTime;
|
||||
|
||||
// 更新位置
|
||||
entity.x += entity.vx * deltaTime;
|
||||
entity.y += entity.vy * deltaTime;
|
||||
|
||||
// 应用摩擦力
|
||||
entity.vx *= config.friction;
|
||||
entity.vy *= config.friction;
|
||||
|
||||
return entity;
|
||||
});
|
||||
}
|
||||
|
||||
protected applyResult(entity: Entity, result: PhysicsData): void {
|
||||
const transform = entity.getComponent(Transform);
|
||||
const velocity = entity.getComponent(Velocity);
|
||||
|
||||
transform.x = result.x;
|
||||
transform.y = result.y;
|
||||
velocity.x = result.vx;
|
||||
velocity.y = result.vy;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 使用预先创建的 Worker 文件(可选)
|
||||
|
||||
如果你希望使用预先创建的 Worker 文件:
|
||||
|
||||
```typescript
|
||||
// 1. 在 game.json 中配置 Worker 路径
|
||||
/*
|
||||
{
|
||||
"workers": "workers"
|
||||
}
|
||||
*/
|
||||
|
||||
// 2. 创建 workers/physics.js 文件
|
||||
// workers/physics.js 内容:
|
||||
/*
|
||||
// 微信小游戏 Worker 使用标准的 self.onmessage
|
||||
self.onmessage = function(e) {
|
||||
const { type, id, entities, deltaTime, systemConfig } = e.data;
|
||||
|
||||
if (entities) {
|
||||
// 处理物理计算
|
||||
const results = entities.map(entity => {
|
||||
entity.vy += systemConfig.gravity * deltaTime;
|
||||
entity.x += entity.vx * deltaTime;
|
||||
entity.y += entity.vy * deltaTime;
|
||||
return entity;
|
||||
});
|
||||
|
||||
self.postMessage({ id, result: results });
|
||||
}
|
||||
};
|
||||
*/
|
||||
|
||||
// 3. 通过平台适配器直接创建(不推荐,WorkerEntitySystem会自动处理)
|
||||
const adapter = PlatformManager.getInstance().getAdapter();
|
||||
const worker = adapter.createWorker('workers/physics.js');
|
||||
```
|
||||
|
||||
### 4. 获取设备信息
|
||||
|
||||
```typescript
|
||||
const manager = PlatformManager.getInstance();
|
||||
if (manager.hasAdapter()) {
|
||||
const adapter = manager.getAdapter();
|
||||
console.log('微信设备信息:', adapter.getDeviceInfo());
|
||||
}
|
||||
```
|
||||
|
||||
## 官方文档参考
|
||||
|
||||
在使用微信小游戏 Worker 之前,建议先阅读官方文档:
|
||||
|
||||
- [wx.createWorker API](https://developers.weixin.qq.com/minigame/dev/api/worker/wx.createWorker.html)
|
||||
- [Worker.postMessage API](https://developers.weixin.qq.com/minigame/dev/api/worker/Worker.postMessage.html)
|
||||
- [Worker.onMessage API](https://developers.weixin.qq.com/minigame/dev/api/worker/Worker.onMessage.html)
|
||||
- [Worker.terminate API](https://developers.weixin.qq.com/minigame/dev/api/worker/Worker.terminate.html)
|
||||
|
||||
## 重要注意事项
|
||||
|
||||
### Worker 限制和配置
|
||||
|
||||
微信小游戏的 Worker 有以下限制:
|
||||
|
||||
- **数量限制**: 最多只能创建 1 个 Worker
|
||||
- **版本要求**: 需要基础库 1.9.90 及以上版本
|
||||
- **脚本支持**: 不支持 blob URL,只能使用文件路径或写入文件系统
|
||||
- **文件路径**: Worker 脚本路径必须为绝对路径,但不能以 "/" 开头
|
||||
- **生命周期**: 创建新 Worker 前必须先调用 `Worker.terminate()` 终止当前 Worker
|
||||
- **消息处理**: Worker 内使用标准的 `self.onmessage`,主线程使用 `worker.onMessage()`
|
||||
- **实验性功能**: 支持 `useExperimentalWorker` 选项获得更好的 iOS 性能
|
||||
|
||||
#### Worker 配置(可选)
|
||||
|
||||
如果使用预先创建的 Worker 文件,需要在 `game.json` 中添加 workers 配置:
|
||||
|
||||
```json
|
||||
{
|
||||
"deviceOrientation": "portrait",
|
||||
"showStatusBar": false,
|
||||
"workers": "workers",
|
||||
"subpackages": []
|
||||
}
|
||||
```
|
||||
|
||||
**注意**: 使用 WorkerEntitySystem 时无需此配置,框架会自动将脚本写入临时文件。
|
||||
|
||||
### 内存限制
|
||||
|
||||
微信小游戏有严格的内存限制:
|
||||
|
||||
- 通常限制在 256MB - 512MB
|
||||
- 需要及时释放不用的资源
|
||||
- 避免内存泄漏
|
||||
|
||||
### API 限制
|
||||
|
||||
- 不支持 `eval()` 函数
|
||||
- 不支持 `Function` 构造器
|
||||
- DOM API 受限
|
||||
- 文件系统 API 受限
|
||||
|
||||
## 性能优化建议
|
||||
|
||||
### 1. 分帧处理
|
||||
|
||||
```typescript
|
||||
class FramedProcessor {
|
||||
private tasks: (() => void)[] = [];
|
||||
private isProcessing = false;
|
||||
|
||||
public addTask(task: () => void): void {
|
||||
this.tasks.push(task);
|
||||
if (!this.isProcessing) {
|
||||
this.processNextFrame();
|
||||
}
|
||||
}
|
||||
|
||||
private processNextFrame(): void {
|
||||
this.isProcessing = true;
|
||||
const startTime = Date.now();
|
||||
const frameTime = 16; // 16ms per frame
|
||||
|
||||
while (this.tasks.length > 0 && Date.now() - startTime < frameTime) {
|
||||
const task = this.tasks.shift();
|
||||
if (task) task();
|
||||
}
|
||||
|
||||
if (this.tasks.length > 0) {
|
||||
setTimeout(() => this.processNextFrame(), 0);
|
||||
} else {
|
||||
this.isProcessing = false;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 内存管理
|
||||
|
||||
```typescript
|
||||
class MemoryManager {
|
||||
private static readonly MAX_MEMORY = 256 * 1024 * 1024; // 256MB
|
||||
|
||||
public static checkMemoryUsage(): void {
|
||||
if (typeof wx !== 'undefined' && wx.getPerformance) {
|
||||
const performance = wx.getPerformance();
|
||||
const memoryInfo = performance.getEntries().find(
|
||||
(entry: any) => entry.entryType === 'memory'
|
||||
);
|
||||
|
||||
if (memoryInfo && memoryInfo.usedJSHeapSize > this.MAX_MEMORY * 0.8) {
|
||||
console.warn('内存使用率过高,建议清理资源');
|
||||
// 触发垃圾回收或资源清理
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 调试技巧
|
||||
|
||||
```typescript
|
||||
// 检查微信小游戏环境
|
||||
if (typeof wx !== 'undefined') {
|
||||
const adapter = new WeChatMiniGameAdapter();
|
||||
|
||||
console.log('微信版本:', adapter.version);
|
||||
console.log('设备信息:', adapter.getDeviceInfo());
|
||||
console.log('平台配置:', adapter.getPlatformConfig());
|
||||
|
||||
// 检查功能支持
|
||||
console.log('Worker支持:', adapter.isWorkerSupported());
|
||||
console.log('SharedArrayBuffer支持:', adapter.isSharedArrayBufferSupported());
|
||||
}
|
||||
```
|
||||
|
||||
## 微信小游戏特殊API
|
||||
|
||||
```typescript
|
||||
// 获取设备性能等级
|
||||
if (typeof wx !== 'undefined' && wx.getDeviceInfo) {
|
||||
wx.getDeviceInfo({
|
||||
success: (res) => {
|
||||
console.log('设备性能等级:', res.benchmarkLevel);
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
// 监听内存警告
|
||||
if (typeof wx !== 'undefined' && wx.onMemoryWarning) {
|
||||
wx.onMemoryWarning(() => {
|
||||
console.warn('收到内存警告,开始清理资源');
|
||||
// 清理不必要的资源
|
||||
});
|
||||
}
|
||||

# 插件系统
|
||||
|
||||
插件系统允许你以模块化的方式扩展 ECS Framework 的功能。通过插件,你可以封装特定功能(如网络同步、物理引擎、调试工具等),并在多个项目中复用。
|
||||
|
||||
## 概述
|
||||
|
||||
### 什么是插件
|
||||
|
||||
插件是实现了 `IPlugin` 接口的类,可以在运行时动态安装到框架中。插件可以:
|
||||
|
||||
- 注册自定义服务到服务容器
|
||||
- 添加系统到场景
|
||||
- 注册自定义组件
|
||||
- 扩展框架功能
|
||||
|
||||
### 插件的优势
|
||||
|
||||
- **模块化**: 将功能封装为独立模块,提高代码可维护性
|
||||
- **可复用**: 同一个插件可以在多个项目中使用
|
||||
- **解耦**: 核心框架与扩展功能分离
|
||||
- **热插拔**: 运行时动态安装和卸载插件
|
||||
|
||||
## 快速开始
|
||||
|
||||
### 创建第一个插件
|
||||
|
||||
创建一个简单的调试插件:
|
||||
|
||||
```typescript
|
||||
import { IPlugin, Core, ServiceContainer } from '@esengine/ecs-framework';
|
||||
|
||||
class DebugPlugin implements IPlugin {
|
||||
readonly name = 'debug-plugin';
|
||||
readonly version = '1.0.0';
|
||||
|
||||
install(core: Core, services: ServiceContainer): void {
|
||||
console.log('Debug plugin installed');
|
||||
|
||||
// 可以在这里注册服务、添加系统等
|
||||
}
|
||||
|
||||
uninstall(): void {
|
||||
console.log('Debug plugin uninstalled');
|
||||
// 清理资源
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 安装插件
|
||||
|
||||
使用 `Core.installPlugin()` 安装插件:
|
||||
|
||||
```typescript
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
|
||||
// 初始化Core
|
||||
Core.create({ debug: true });
|
||||
|
||||
// 安装插件
|
||||
await Core.installPlugin(new DebugPlugin());
|
||||
|
||||
// 检查插件是否已安装
|
||||
if (Core.isPluginInstalled('debug-plugin')) {
|
||||
console.log('Debug plugin is running');
|
||||
}
|
||||
```
|
||||
|
||||
### 卸载插件
|
||||
|
||||
```typescript
|
||||
// 卸载插件
|
||||
await Core.uninstallPlugin('debug-plugin');
|
||||
```
|
||||
|
||||
### 获取插件实例
|
||||
|
||||
```typescript
|
||||
// 获取已安装的插件
|
||||
const plugin = Core.getPlugin('debug-plugin');
|
||||
if (plugin) {
|
||||
console.log(`Plugin version: ${plugin.version}`);
|
||||
}
|
||||
```
|
||||
|
||||
## 插件开发
|
||||
|
||||
### IPlugin 接口
|
||||
|
||||
所有插件必须实现 `IPlugin` 接口:
|
||||
|
||||
```typescript
|
||||
export interface IPlugin {
|
||||
// 插件唯一名称
|
||||
readonly name: string;
|
||||
|
||||
// 插件版本(建议遵循semver规范)
|
||||
readonly version: string;
|
||||
|
||||
// 依赖的其他插件(可选)
|
||||
readonly dependencies?: readonly string[];
|
||||
|
||||
// 安装插件时调用
|
||||
install(core: Core, services: ServiceContainer): void | Promise<void>;
|
||||
|
||||
// 卸载插件时调用
|
||||
uninstall(): void | Promise<void>;
|
||||
}
|
||||
```
|
||||
|
||||
### 插件生命周期
|
||||
|
||||
#### install 方法
|
||||
|
||||
在插件安装时调用,用于初始化插件:
|
||||
|
||||
```typescript
|
||||
class MyPlugin implements IPlugin {
|
||||
readonly name = 'my-plugin';
|
||||
readonly version = '1.0.0';
|
||||
|
||||
install(core: Core, services: ServiceContainer): void {
|
||||
// 1. 注册服务
|
||||
services.registerSingleton(MyService);
|
||||
|
||||
// 2. 访问当前场景
|
||||
const scene = core.scene;
|
||||
if (scene) {
|
||||
// 3. 添加系统
|
||||
scene.addSystem(new MySystem());
|
||||
}
|
||||
|
||||
// 4. 其他初始化逻辑
|
||||
console.log('Plugin initialized');
|
||||
}
|
||||
|
||||
uninstall(): void {
|
||||
// 清理逻辑
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### uninstall 方法
|
||||
|
||||
在插件卸载时调用,用于清理资源:
|
||||
|
||||
```typescript
|
||||
class MyPlugin implements IPlugin {
|
||||
readonly name = 'my-plugin';
|
||||
readonly version = '1.0.0';
|
||||
private myService?: MyService;
|
||||
|
||||
install(core: Core, services: ServiceContainer): void {
|
||||
this.myService = new MyService();
|
||||
services.registerInstance(MyService, this.myService);
|
||||
}
|
||||
|
||||
uninstall(): void {
|
||||
// 清理服务
|
||||
if (this.myService) {
|
||||
this.myService.dispose();
|
||||
this.myService = undefined;
|
||||
}
|
||||
|
||||
// 移除事件监听器
|
||||
// 释放其他资源
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 异步插件
|
||||
|
||||
插件的 `install` 和 `uninstall` 方法都支持异步:
|
||||
|
||||
```typescript
|
||||
class AsyncPlugin implements IPlugin {
|
||||
readonly name = 'async-plugin';
|
||||
readonly version = '1.0.0';
|
||||
|
||||
async install(core: Core, services: ServiceContainer): Promise<void> {
|
||||
// 异步加载资源
|
||||
const config = await fetch('/plugin-config.json').then(r => r.json());
|
||||
|
||||
// 使用加载的配置初始化服务
|
||||
const service = new MyService(config);
|
||||
services.registerInstance(MyService, service);
|
||||
}
|
||||
|
||||
async uninstall(): Promise<void> {
|
||||
// 异步清理
|
||||
await this.saveState();
|
||||
}
|
||||
|
||||
private async saveState() {
|
||||
// 保存插件状态
|
||||
}
|
||||
}
|
||||
|
||||
// 使用
|
||||
await Core.installPlugin(new AsyncPlugin());
|
||||
```
|
||||
|
||||
### 注册服务
|
||||
|
||||
插件可以向服务容器注册自己的服务:
|
||||
|
||||
```typescript
|
||||
import { IService } from '@esengine/ecs-framework';
|
||||
|
||||
class NetworkService implements IService {
|
||||
connect(url: string) {
|
||||
console.log(`Connecting to ${url}`);
|
||||
}
|
||||
|
||||
dispose(): void {
|
||||
console.log('Network service disposed');
|
||||
}
|
||||
}
|
||||
|
||||
class NetworkPlugin implements IPlugin {
|
||||
readonly name = 'network-plugin';
|
||||
readonly version = '1.0.0';
|
||||
|
||||
install(core: Core, services: ServiceContainer): void {
|
||||
// 注册网络服务
|
||||
services.registerSingleton(NetworkService);
|
||||
|
||||
// 解析并使用服务
|
||||
const network = services.resolve(NetworkService);
|
||||
network.connect('ws://localhost:8080');
|
||||
}
|
||||
|
||||
uninstall(): void {
|
||||
// 服务容器会自动调用服务的dispose方法
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 添加系统
|
||||
|
||||
插件可以向场景添加自定义系统:
|
||||
|
||||
```typescript
|
||||
import { EntitySystem, Matcher } from '@esengine/ecs-framework';
|
||||
|
||||
class PhysicsSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.empty().all(PhysicsBody));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 物理模拟逻辑
|
||||
}
|
||||
}
|
||||
|
||||
class PhysicsPlugin implements IPlugin {
|
||||
readonly name = 'physics-plugin';
|
||||
readonly version = '1.0.0';
|
||||
private physicsSystem?: PhysicsSystem;
|
||||
|
||||
install(core: Core, services: ServiceContainer): void {
|
||||
const scene = core.scene;
|
||||
if (scene) {
|
||||
this.physicsSystem = new PhysicsSystem();
|
||||
scene.addSystem(this.physicsSystem);
|
||||
}
|
||||
}
|
||||
|
||||
uninstall(): void {
|
||||
// 移除系统
|
||||
if (this.physicsSystem) {
|
||||
const scene = Core.scene;
|
||||
if (scene) {
|
||||
scene.removeSystem(this.physicsSystem);
|
||||
}
|
||||
this.physicsSystem = undefined;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 依赖管理
|
||||
|
||||
### 声明依赖
|
||||
|
||||
插件可以声明对其他插件的依赖:
|
||||
|
||||
```typescript
|
||||
class AdvancedPhysicsPlugin implements IPlugin {
|
||||
readonly name = 'advanced-physics';
|
||||
readonly version = '2.0.0';
|
||||
|
||||
// 声明依赖基础物理插件
|
||||
readonly dependencies = ['physics-plugin'] as const;
|
||||
|
||||
install(core: Core, services: ServiceContainer): void {
|
||||
// 可以安全地使用physics-plugin提供的服务
|
||||
const physicsService = services.resolve(PhysicsService);
|
||||
// ...
|
||||
}
|
||||
|
||||
uninstall(): void {
|
||||
// 清理
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 依赖检查
|
||||
|
||||
框架会自动检查依赖关系,如果依赖未满足会抛出错误:
|
||||
|
||||
```typescript
|
||||
// 错误:physics-plugin 未安装
|
||||
try {
|
||||
await Core.installPlugin(new AdvancedPhysicsPlugin());
|
||||
} catch (error) {
|
||||
console.error(error); // Plugin advanced-physics has unmet dependencies: physics-plugin
|
||||
}
|
||||
|
||||
// 正确:先安装依赖
|
||||
await Core.installPlugin(new PhysicsPlugin());
|
||||
await Core.installPlugin(new AdvancedPhysicsPlugin());
|
||||
```
|
||||
|
||||
### 卸载顺序
|
||||
|
||||
框架会检查依赖关系,防止卸载被其他插件依赖的插件:
|
||||
|
||||
```typescript
|
||||
await Core.installPlugin(new PhysicsPlugin());
|
||||
await Core.installPlugin(new AdvancedPhysicsPlugin());
|
||||
|
||||
// 错误:physics-plugin 被 advanced-physics 依赖
|
||||
try {
|
||||
await Core.uninstallPlugin('physics-plugin');
|
||||
} catch (error) {
|
||||
console.error(error); // Cannot uninstall plugin physics-plugin: it is required by advanced-physics
|
||||
}
|
||||
|
||||
// 正确:先卸载依赖它的插件
|
||||
await Core.uninstallPlugin('advanced-physics');
|
||||
await Core.uninstallPlugin('physics-plugin');
|
||||
```
|
||||
|
||||
## 插件管理
|
||||
|
||||
### 通过 Core 管理
|
||||
|
||||
Core 类提供了便捷的插件管理方法:
|
||||
|
||||
```typescript
|
||||
// 安装插件
|
||||
await Core.installPlugin(myPlugin);
|
||||
|
||||
// 卸载插件
|
||||
await Core.uninstallPlugin('plugin-name');
|
||||
|
||||
// 检查插件是否已安装
|
||||
if (Core.isPluginInstalled('plugin-name')) {
|
||||
// ...
|
||||
}
|
||||
|
||||
// 获取插件实例
|
||||
const plugin = Core.getPlugin('plugin-name');
|
||||
```
|
||||
|
||||
### 通过 PluginManager 管理
|
||||
|
||||
也可以直接使用 PluginManager 服务:
|
||||
|
||||
```typescript
|
||||
const pluginManager = Core.services.resolve(PluginManager);
|
||||
|
||||
// 获取所有插件
|
||||
const allPlugins = pluginManager.getAllPlugins();
|
||||
console.log(`Total plugins: ${allPlugins.length}`);
|
||||
|
||||
// 获取插件元数据
|
||||
const metadata = pluginManager.getMetadata('my-plugin');
|
||||
if (metadata) {
|
||||
console.log(`State: ${metadata.state}`);
|
||||
console.log(`Installed at: ${new Date(metadata.installedAt!)}`);
|
||||
}
|
||||
|
||||
// 获取所有插件元数据
|
||||
const allMetadata = pluginManager.getAllMetadata();
|
||||
for (const meta of allMetadata) {
|
||||
console.log(`${meta.name} v${meta.version} - ${meta.state}`);
|
||||
}
|
||||
```
|
||||
|
||||
## 实用插件示例
|
||||
|
||||
### 网络同步插件
|
||||
|
||||
```typescript
|
||||
import { IPlugin, IService, Core, ServiceContainer } from '@esengine/ecs-framework';
|
||||
|
||||
class NetworkSyncService implements IService {
|
||||
private ws?: WebSocket;
|
||||
|
||||
connect(url: string) {
|
||||
this.ws = new WebSocket(url);
|
||||
this.ws.onmessage = (event) => {
|
||||
const data = JSON.parse(event.data);
|
||||
this.handleMessage(data);
|
||||
};
|
||||
}
|
||||
|
||||
private handleMessage(data: any) {
|
||||
// 处理网络消息
|
||||
}
|
||||
|
||||
dispose(): void {
|
||||
if (this.ws) {
|
||||
this.ws.close();
|
||||
this.ws = undefined;
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
class NetworkSyncPlugin implements IPlugin {
|
||||
readonly name = 'network-sync';
|
||||
readonly version = '1.0.0';
|
||||
|
||||
install(core: Core, services: ServiceContainer): void {
|
||||
// 注册网络服务
|
||||
services.registerSingleton(NetworkSyncService);
|
||||
|
||||
// 自动连接
|
||||
const network = services.resolve(NetworkSyncService);
|
||||
network.connect('ws://localhost:8080');
|
||||
}
|
||||
|
||||
uninstall(): void {
|
||||
// 服务会自动dispose
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 性能分析插件
|
||||
|
||||
```typescript
|
||||
class PerformanceAnalysisPlugin implements IPlugin {
|
||||
readonly name = 'performance-analysis';
|
||||
readonly version = '1.0.0';
|
||||
private frameCount = 0;
|
||||
private totalTime = 0;
|
||||
|
||||
install(core: Core, services: ServiceContainer): void {
|
||||
const monitor = services.resolve(PerformanceMonitor);
|
||||
monitor.enable();
|
||||
|
||||
// 定期输出性能报告
|
||||
const timer = services.resolve(TimerManager);
|
||||
timer.schedule(5.0, true, null, () => {
|
||||
this.printReport(monitor);
|
||||
});
|
||||
}
|
||||
|
||||
uninstall(): void {
|
||||
// 清理
|
||||
}
|
||||
|
||||
private printReport(monitor: PerformanceMonitor) {
|
||||
console.log('=== Performance Report ===');
|
||||
console.log(`FPS: ${monitor.getFPS()}`);
|
||||
console.log(`Memory: ${monitor.getMemoryUsage()} MB`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 命名规范
|
||||
|
||||
- 插件名称使用小写字母和连字符:`my-awesome-plugin`
|
||||
- 版本号遵循语义化版本规范:`1.0.0`
|
||||
|
||||
```typescript
|
||||
class MyPlugin implements IPlugin {
|
||||
readonly name = 'my-awesome-plugin'; // 好
|
||||
readonly version = '1.0.0'; // 好
|
||||
}
|
||||
```
|
||||
|
||||
### 清理资源
|
||||
|
||||
始终在 `uninstall` 中清理插件创建的所有资源:
|
||||
|
||||
```typescript
|
||||
class MyPlugin implements IPlugin {
|
||||
readonly name = 'my-plugin';
|
||||
readonly version = '1.0.0';
|
||||
private timerId?: number;
|
||||
private listener?: () => void;
|
||||
|
||||
install(core: Core, services: ServiceContainer): void {
|
||||
// 添加定时器
|
||||
this.timerId = setInterval(() => {
|
||||
// ...
|
||||
}, 1000);
|
||||
|
||||
// 添加事件监听
|
||||
this.listener = () => {};
|
||||
window.addEventListener('resize', this.listener);
|
||||
}
|
||||
|
||||
uninstall(): void {
|
||||
// 清理定时器
|
||||
if (this.timerId) {
|
||||
clearInterval(this.timerId);
|
||||
this.timerId = undefined;
|
||||
}
|
||||
|
||||
// 移除事件监听
|
||||
if (this.listener) {
|
||||
window.removeEventListener('resize', this.listener);
|
||||
this.listener = undefined;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 错误处理
|
||||
|
||||
在插件中妥善处理错误,避免影响整个应用:
|
||||
|
||||
```typescript
|
||||
class MyPlugin implements IPlugin {
|
||||
readonly name = 'my-plugin';
|
||||
readonly version = '1.0.0';
|
||||
|
||||
async install(core: Core, services: ServiceContainer): Promise<void> {
|
||||
try {
|
||||
// 可能失败的操作
|
||||
await this.loadConfig();
|
||||
} catch (error) {
|
||||
console.error('Failed to load plugin config:', error);
|
||||
throw error; // 重新抛出,让框架知道安装失败
|
||||
}
|
||||
}
|
||||
|
||||
async uninstall(): Promise<void> {
|
||||
try {
|
||||
await this.cleanup();
|
||||
} catch (error) {
|
||||
console.error('Failed to cleanup plugin:', error);
|
||||
// 即使清理失败也不应该阻止卸载
|
||||
}
|
||||
}
|
||||
|
||||
private async loadConfig() {
|
||||
// 加载配置
|
||||
}
|
||||
|
||||
private async cleanup() {
|
||||
// 清理
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 配置化
|
||||
|
||||
允许用户配置插件行为:
|
||||
|
||||
```typescript
|
||||
interface NetworkPluginConfig {
|
||||
serverUrl: string;
|
||||
autoReconnect: boolean;
|
||||
timeout: number;
|
||||
}
|
||||
|
||||
class NetworkPlugin implements IPlugin {
|
||||
readonly name = 'network-plugin';
|
||||
readonly version = '1.0.0';
|
||||
|
||||
constructor(private config: NetworkPluginConfig) {}
|
||||
|
||||
install(core: Core, services: ServiceContainer): void {
|
||||
const network = new NetworkService(this.config);
|
||||
services.registerInstance(NetworkService, network);
|
||||
}
|
||||
|
||||
uninstall(): void {
|
||||
// 清理
|
||||
}
|
||||
}
|
||||
|
||||
// 使用
|
||||
const plugin = new NetworkPlugin({
|
||||
serverUrl: 'ws://localhost:8080',
|
||||
autoReconnect: true,
|
||||
timeout: 5000
|
||||
});
|
||||
|
||||
await Core.installPlugin(plugin);
|
||||
```
|
||||
|
||||
## 常见问题

||||
- 自动处理场景生命周期
|
||||
- 集成在 Core 中,自动更新
|
||||
|
||||
## 基本使用
|
||||
|
||||
### 推荐方式:使用 Core 的静态方法
|
||||
|
||||
这是最简单和推荐的方式,适合大多数应用:
|
||||
|
||||
```typescript
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
|
||||
// 1. 初始化 Core
|
||||
Core.create({ debug: true });
|
||||
|
||||
// 2. 创建并设置场景
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
this.name = "GameScene";
|
||||
|
||||
// 添加系统
|
||||
this.addSystem(new MovementSystem());
|
||||
this.addSystem(new RenderSystem());
|
||||
|
||||
// 创建初始实体
|
||||
const player = this.createEntity("Player");
|
||||
player.addComponent(new Transform(400, 300));
|
||||
player.addComponent(new Health(100));
|
||||
}
|
||||
|
||||
public onStart(): void {
|
||||
console.log("游戏场景已启动");
|
||||
}
|
||||
}
|
||||
|
||||
// 3. 设置场景
|
||||
Core.setScene(new GameScene());
|
||||
|
||||
// 4. 游戏循环(Core.update 会自动更新场景)
|
||||
function gameLoop(deltaTime: number) {
|
||||
Core.update(deltaTime); // 自动更新所有服务和场景
|
||||
}
|
||||
|
||||
// Laya 引擎集成
|
||||
Laya.timer.frameLoop(1, this, () => {
|
||||
const deltaTime = Laya.timer.delta / 1000;
|
||||
Core.update(deltaTime);
|
||||
});
|
||||
|
||||
// Cocos Creator 集成
|
||||
update(deltaTime: number) {
|
||||
Core.update(deltaTime);
|
||||
}
|
||||
```
|
||||
|
||||
### 高级方式:直接使用 SceneManager
|
||||
|
||||
如果需要更多控制,可以直接使用 SceneManager:
|
||||
|
||||
```typescript
|
||||
import { Core, SceneManager, Scene } from '@esengine/ecs-framework';
|
||||
|
||||
// 初始化 Core
|
||||
Core.create({ debug: true });
|
||||
|
||||
// 获取 SceneManager(Core 已自动创建并注册)
|
||||
const sceneManager = Core.services.resolve(SceneManager);
|
||||
|
||||
// 设置场景
|
||||
const gameScene = new GameScene();
|
||||
sceneManager.setScene(gameScene);
|
||||
|
||||
// 游戏循环(仍然使用 Core.update)
|
||||
function gameLoop(deltaTime: number) {
|
||||
Core.update(deltaTime); // Core会自动调用sceneManager.update()
|
||||
}
|
||||
```
|
||||
|
||||
**重要**:无论使用哪种方式,游戏循环中都应该只调用 `Core.update()`,它会自动更新 SceneManager 和场景。不需要手动调用 `sceneManager.update()`。
|
||||
|
||||
## 场景切换
|
||||
|
||||
### 立即切换
|
||||
|
||||
使用 `Core.setScene()` 或 `sceneManager.setScene()` 立即切换场景:
|
||||
|
||||
```typescript
|
||||
// 方式1:使用 Core(推荐)
|
||||
Core.setScene(new MenuScene());
|
||||
|
||||
// 方式2:使用 SceneManager
|
||||
const sceneManager = Core.services.resolve(SceneManager);
|
||||
sceneManager.setScene(new MenuScene());
|
||||
```
|
||||
|
||||
### 延迟切换
|
||||
|
||||
使用 `Core.loadScene()` 或 `sceneManager.loadScene()` 延迟切换场景,场景会在下一帧切换:
|
||||
|
||||
```typescript
|
||||
// 方式1:使用 Core(推荐)
|
||||
Core.loadScene(new GameOverScene());
|
||||
|
||||
// 方式2:使用 SceneManager
|
||||
const sceneManager = Core.services.resolve(SceneManager);
|
||||
sceneManager.loadScene(new GameOverScene());
|
||||
```
|
||||
|
||||
在 System 中切换场景时,应该使用延迟切换:
|
||||
|
||||
```typescript
|
||||
class GameOverSystem extends EntitySystem {
|
||||
process(entities: readonly Entity[]): void {
|
||||
const player = entities.find(e => e.name === 'Player');
|
||||
const health = player?.getComponent(Health);
|
||||
|
||||
if (health && health.value <= 0) {
|
||||
// 延迟切换到游戏结束场景(下一帧生效)
|
||||
Core.loadScene(new GameOverScene());
|
||||
// 当前帧继续执行,不会中断当前系统的处理
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 完整的场景切换示例
|
||||
|
||||
```typescript
|
||||
import { Core, Scene } from '@esengine/ecs-framework';
|
||||
|
||||
// 初始化
|
||||
Core.create({ debug: true });
|
||||
|
||||
// 菜单场景
|
||||
class MenuScene extends Scene {
|
||||
protected initialize(): void {
|
||||
this.name = "MenuScene";
|
||||
|
||||
// 监听开始游戏事件
|
||||
this.eventSystem.on('start_game', () => {
|
||||
Core.loadScene(new GameScene());
|
||||
});
|
||||
}
|
||||
|
||||
public onStart(): void {
|
||||
console.log("显示菜单界面");
|
||||
}
|
||||
|
||||
public unload(): void {
|
||||
console.log("菜单场景卸载");
|
||||
}
|
||||
}
|
||||
|
||||
// 游戏场景
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
this.name = "GameScene";
|
||||
|
||||
// 创建游戏实体
|
||||
const player = this.createEntity("Player");
|
||||
player.addComponent(new Transform(400, 300));
|
||||
player.addComponent(new Health(100));
|
||||
|
||||
// 监听游戏结束事件
|
||||
this.eventSystem.on('game_over', () => {
|
||||
Core.loadScene(new GameOverScene());
|
||||
});
|
||||
}
|
||||
|
||||
public onStart(): void {
|
||||
console.log("游戏开始");
|
||||
}
|
||||
|
||||
public unload(): void {
|
||||
console.log("游戏场景卸载");
|
||||
}
|
||||
}
|
||||
|
||||
// 游戏结束场景
|
||||
class GameOverScene extends Scene {
|
||||
protected initialize(): void {
|
||||
this.name = "GameOverScene";
|
||||
|
||||
// 监听返回菜单事件
|
||||
this.eventSystem.on('back_to_menu', () => {
|
||||
Core.loadScene(new MenuScene());
|
||||
});
|
||||
}
|
||||
|
||||
public onStart(): void {
|
||||
console.log("显示游戏结束界面");
|
||||
}
|
||||
}
|
||||
|
||||
// 开始游戏
|
||||
Core.setScene(new MenuScene());
|
||||
|
||||
// 游戏循环
|
||||
function gameLoop(deltaTime: number) {
|
||||
Core.update(deltaTime); // 自动更新场景
|
||||
}
|
||||
```
|
||||

||||
## API 参考
|
||||
|
||||
### Core 静态方法(推荐)
|
||||
|
||||
#### Core.setScene()
|
||||
|
||||
立即切换场景。
|
||||
|
||||
```typescript
|
||||
public static setScene<T extends IScene>(scene: T): T
|
||||
```
|
||||
|
||||
**参数**:
|
||||
- `scene` - 要设置的场景实例
|
||||
|
||||
**返回**:
|
||||
- 返回设置的场景实例
|
||||
|
||||
**示例**:
|
||||
```typescript
|
||||
const gameScene = Core.setScene(new GameScene());
|
||||
console.log(gameScene.name);
|
||||
```
|
||||
|
||||
#### Core.loadScene()
|
||||
|
||||
延迟加载场景(下一帧切换)。
|
||||
|
||||
```typescript
|
||||
public static loadScene<T extends IScene>(scene: T): void
|
||||
```
|
||||
|
||||
**参数**:
|
||||
- `scene` - 要加载的场景实例
|
||||
|
||||
**示例**:
|
||||
```typescript
|
||||
Core.loadScene(new GameOverScene());
|
||||
```
|
||||
|
||||
#### Core.scene
|
||||
|
||||
获取当前活跃的场景。
|
||||
|
||||
```typescript
|
||||
public static get scene(): IScene | null
|
||||
```
|
||||
|
||||
**返回**:
|
||||
- 当前场景实例,如果没有场景则返回 null
|
||||
|
||||
**示例**:
|
||||
```typescript
|
||||
const currentScene = Core.scene;
|
||||
if (currentScene) {
|
||||
console.log(`当前场景: ${currentScene.name}`);
|
||||
}
|
||||
```
|
||||
|
||||
#### Core.ecsAPI
|
||||
|
||||
获取 ECS 流式 API。
|
||||
|
||||
```typescript
|
||||
public static get ecsAPI(): ECSFluentAPI | null
|
||||
```
|
||||
|
||||
**返回**:
|
||||
- ECS API 实例,如果当前没有场景则返回 null
|
||||
|
||||
**示例**:
|
||||
```typescript
|
||||
const api = Core.ecsAPI;
|
||||
if (api) {
|
||||
// 查询实体
|
||||
const enemies = api.find(Enemy, Transform);
|
||||
|
||||
// 发射事件
|
||||
api.emit('game:start', { level: 1 });
|
||||
}
|
||||
```
|
||||
|
||||
### SceneManager 方法(高级)
|
||||
|
||||
如果需要直接使用 SceneManager,可以通过服务容器获取:
|
||||
|
||||
```typescript
|
||||
const sceneManager = Core.services.resolve(SceneManager);
|
||||
```
|
||||
|
||||
#### setScene()
|
||||
|
||||
立即切换场景。
|
||||
|
||||
```typescript
|
||||
public setScene<T extends IScene>(scene: T): T
|
||||
```
|
||||
|
||||
#### loadScene()
|
||||
|
||||
延迟加载场景。
|
||||
|
||||
```typescript
|
||||
public loadScene<T extends IScene>(scene: T): void
|
||||
```
|
||||
|
||||
#### currentScene
|
||||
|
||||
获取当前场景。
|
||||
|
||||
```typescript
|
||||
public get currentScene(): IScene | null
|
||||
```
|
||||
|
||||
#### api
|
||||
|
||||
获取 ECS 流式 API。
|
||||
|
||||
```typescript
|
||||
public get api(): ECSFluentAPI | null
|
||||
```
|
||||
|
||||
#### hasScene
|
||||
|
||||
检查是否有活跃场景。
|
||||
|
||||
```typescript
|
||||
public get hasScene(): boolean
|
||||
```
|
||||
|
||||
#### hasPendingScene
|
||||
|
||||
检查是否有待切换的场景。
|
||||
|
||||
```typescript
|
||||
public get hasPendingScene(): boolean
|
||||
```
|
||||
|
||||
## 使用 ECS 流式 API
|
||||
|
||||
通过 `Core.ecsAPI` 可以方便地访问场景的 ECS 功能:
|
||||
|
||||
```typescript
|
||||
const api = Core.ecsAPI;
|
||||
if (!api) {
|
||||
console.error('没有活跃场景');
|
||||
return;
|
||||
}
|
||||
|
||||
// 查询实体
|
||||
const players = api.find(Player, Transform);
|
||||
const enemies = api.find(Enemy, Health, Transform);
|
||||
|
||||
// 发射事件
|
||||
api.emit('player:scored', { points: 100 });
|
||||
|
||||
// 监听事件
|
||||
api.on('enemy:died', (data) => {
|
||||
console.log('敌人死亡:', data);
|
||||
});
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 使用 Core 的静态方法
|
||||
|
||||
```typescript
|
||||
// 推荐:使用 Core 的静态方法
|
||||
Core.setScene(new GameScene());
|
||||
Core.loadScene(new MenuScene());
|
||||
const currentScene = Core.scene;
|
||||
|
||||
// 不推荐:除非有特殊需求,否则不需要直接使用 SceneManager
|
||||
const sceneManager = Core.services.resolve(SceneManager);
|
||||
sceneManager.setScene(new GameScene());
|
||||
```
|
||||
|
||||
### 2. 只调用 Core.update()
|
||||
|
||||
```typescript
|
||||
// 正确:只调用 Core.update()
|
||||
function gameLoop(deltaTime: number) {
|
||||
Core.update(deltaTime); // 自动更新所有服务和场景
|
||||
}
|
||||
|
||||
// 错误:不要手动调用 sceneManager.update()
|
||||
function gameLoop(deltaTime: number) {
|
||||
Core.update(deltaTime);
|
||||
sceneManager.update(); // 重复更新,会导致问题!
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 使用延迟切换避免问题
|
||||
|
||||
在 System 中切换场景时,应该使用 `loadScene()` 而不是 `setScene()`:
|
||||
|
||||
```typescript
|
||||
// 推荐:延迟切换
|
||||
class HealthSystem extends EntitySystem {
|
||||
process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const health = entity.getComponent(Health);
|
||||
if (health.value <= 0) {
|
||||
Core.loadScene(new GameOverScene());
|
||||
// 当前帧继续处理其他实体
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// 不推荐:立即切换可能导致问题
|
||||
class HealthSystem extends EntitySystem {
|
||||
process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const health = entity.getComponent(Health);
|
||||
if (health.value <= 0) {
|
||||
Core.setScene(new GameOverScene());
|
||||
// 场景立即切换,当前帧的其他实体可能无法正常处理
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 场景职责分离
|
||||
|
||||
每个场景应该只负责一个特定的游戏状态:
|
||||
|
||||
```typescript
|
||||
// 好的设计 - 职责清晰
|
||||
class MenuScene extends Scene {
|
||||
// 只处理菜单相关逻辑
|
||||
}
|
||||
|
||||
class GameScene extends Scene {
|
||||
// 只处理游戏玩法逻辑
|
||||
}
|
||||
|
||||
class PauseScene extends Scene {
|
||||
// 只处理暂停界面逻辑
|
||||
}
|
||||
|
||||
// 避免的设计 - 职责混乱
|
||||
class MegaScene extends Scene {
|
||||
// 包含菜单、游戏、暂停等所有逻辑
|
||||
}
|
||||
```
|
||||
|
||||
### 5. 资源管理
|
||||
|
||||
在场景的 `unload()` 方法中清理资源:
|
||||
|
||||
```typescript
|
||||
class GameScene extends Scene {
|
||||
private textures: Map<string, any> = new Map();
|
||||
private sounds: Map<string, any> = new Map();
|
||||
|
||||
protected initialize(): void {
|
||||
this.loadResources();
|
||||
}
|
||||
|
||||
private loadResources(): void {
|
||||
this.textures.set('player', loadTexture('player.png'));
|
||||
this.sounds.set('bgm', loadSound('bgm.mp3'));
|
||||
}
|
||||
|
||||
public unload(): void {
|
||||
// 清理资源
|
||||
this.textures.clear();
|
||||
this.sounds.clear();
|
||||
console.log('场景资源已清理');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 6. 事件驱动的场景切换
|
||||
|
||||
使用事件系统来触发场景切换,保持代码解耦:
|
||||
|
||||
```typescript
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 监听场景切换事件
|
||||
this.eventSystem.on('goto:menu', () => {
|
||||
Core.loadScene(new MenuScene());
|
||||
});
|
||||
|
||||
this.eventSystem.on('goto:gameover', (data) => {
|
||||
Core.loadScene(new GameOverScene());
|
||||
});
|
||||
}
|
||||
}
|
||||
|
||||
// 在 System 中触发事件
|
||||
class GameLogicSystem extends EntitySystem {
|
||||
process(entities: readonly Entity[]): void {
|
||||
if (levelComplete) {
|
||||
this.scene.eventSystem.emitSync('goto:gameover', {
|
||||
score: 1000,
|
||||
level: 5
|
||||
});
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 架构层次
|
||||
|
||||
SceneManager 在 ECS Framework 中的位置:
|
||||
|
||||
```
|
||||
Core (全局服务)
|
||||
└── SceneManager (场景管理,自动更新)
|
||||
└── Scene (当前场景)
|
||||
├── EntitySystem (系统)
|
||||
├── Entity (实体)
|
||||
└── Component (组件)
|
||||
```
|
||||
|
||||
## 与 WorldManager 的对比
|
||||
|
||||
| 特性 | SceneManager | WorldManager |
|
||||
|------|--------------|--------------|
|
||||
| 适用场景 | 95% 的游戏应用 | 高级多世界隔离场景 |
|
||||
| 复杂度 | 简单 | 复杂 |
|
||||
| 场景数量 | 单场景(可切换) | 多 World,每个 World 多场景 |
|
||||
| 性能开销 | 最小 | 较高 |
|
||||
| 使用方式 | `Core.setScene()` | `worldManager.createWorld()` |
|
||||
|
||||
**何时使用 SceneManager**:
|
||||
- 单人游戏
|
||||
- 简单的多人游戏
|
||||
- 移动游戏
|
||||
- 场景之间需要切换但不需要同时运行
|
||||
|
||||
**何时使用 WorldManager**:
|
||||
- MMO 游戏服务器(每个房间一个 World)
|
||||
- 游戏大厅系统(每个游戏房间完全隔离)
|
||||
- 需要运行多个完全独立的游戏实例
|
||||
|
||||
## 完整示例
|
||||
|
||||
```typescript
|
||||
import { Core, Scene, EntitySystem, Entity, Matcher } from '@esengine/ecs-framework';
|
||||
|
||||
// 定义组件
|

player.addComponent(new Transform(400, 300));
|

player.addComponent(new Velocity(0, 0));
|
||||
player.addComponent(new Health(100));
|
||||
|
||||
// 创建敌人
|
||||
for (let i = 0; i < 5; i++) {
|
||||
const enemy = this.createEntity(`Enemy_${i}`);
|
||||
enemy.addComponent(new Transform(
|
||||
Math.random() * 800,
|
||||
Math.random() * 600
|
||||
));
|
||||
enemy.addComponent(new Velocity(
|
||||
Math.random() * 100 - 50,
|
||||
Math.random() * 100 - 50
|
||||
));
|
||||
enemy.addComponent(new Health(50));
|
||||
}
|
||||
}
|
||||
|
||||
public onStart(): void {
|
||||
console.log('游戏场景启动');
|
||||
}
|
||||
|
||||
public unload(): void {
|
||||
console.log('游戏场景卸载');
|
||||
}
|
||||
}
|
||||
|
||||
// 初始化
|
||||
Core.create({ debug: true });
|
||||
|
||||
// 设置初始场景
|
||||
Core.setScene(new MenuScene());
|
||||
|
||||
// 游戏循环
|
||||
let lastTime = 0;
|
||||
function gameLoop(currentTime: number) {
|
||||
const deltaTime = (currentTime - lastTime) / 1000;
|
||||
lastTime = currentTime;
|
||||
|
||||
// 只需要调用 Core.update,它会自动更新场景
|
||||
Core.update(deltaTime);
|
||||
|
||||
requestAnimationFrame(gameLoop);
|
||||
}
|
||||
|
||||
requestAnimationFrame(gameLoop);
|
||||
|
||||
// 切换到游戏场景
|
||||
setTimeout(() => {
|
||||
Core.loadScene(new GameScene());
|
||||
}, 3000);
|
||||
```
|
||||
|
||||
SceneManager 为大多数游戏提供了简单而强大的场景管理能力。通过 Core 的静态方法,你可以轻松地管理场景切换。如果你需要更高级的多世界隔离功能,请参考 [WorldManager](./world-manager.md) 文档。

# 场景管理
|
||||
|
||||
在 ECS 架构中,场景(Scene)是游戏世界的容器,负责管理实体、系统和组件的生命周期。场景提供了完整的 ECS 运行环境。
|
||||
|
||||
## 基本概念
|
||||
|
||||
场景是 ECS 框架的核心容器,提供:
|
||||
- 实体的创建、管理和销毁
|
||||
- 系统的注册和执行调度
|
||||
- 组件的存储和查询
|
||||
- 事件系统支持
|
||||
- 性能监控和调试信息
|
||||
|
||||
## 场景管理方式
|
||||
|
||||
ECS Framework 提供了两种场景管理方式:
|
||||
|
||||
1. **[SceneManager](./scene-manager.md)** - 适用于 95% 的游戏应用
|
||||
- 单人游戏、简单多人游戏、移动游戏
|
||||
- 轻量级,简单直观的 API
|
||||
- 支持场景切换
|
||||
|
||||
2. **[WorldManager](./world-manager.md)** - 适用于高级多世界隔离场景
|
||||
- MMO 游戏服务器、游戏房间系统
|
||||
- 多 World 管理,每个 World 可包含多个场景
|
||||
- 完全隔离的独立环境
|
||||
|
||||
本文档重点介绍 Scene 类本身的使用方法。关于场景管理器的详细信息,请查看对应的文档。
|
||||
|
||||
## 创建场景
|
||||
|
||||
### 继承 Scene 类
|
||||
|
||||
**推荐做法:继承 Scene 类来创建自定义场景**
|
||||
|
||||
```typescript
|
||||
import { Scene, EntitySystem } from '@esengine/ecs-framework';
|
||||
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 设置场景名称
|
||||
this.name = "GameScene";
|
||||
|
||||
// 添加系统
|
||||
this.addSystem(new MovementSystem());
|
||||
this.addSystem(new RenderSystem());
|
||||
this.addSystem(new PhysicsSystem());
|
||||
|
||||
// 创建初始实体
|
||||
this.createInitialEntities();
|
||||
}
|
||||
|
||||
private createInitialEntities(): void {
|
||||
// 创建玩家
|
||||
const player = this.createEntity("Player");
|
||||
player.addComponent(new Position(400, 300));
|
||||
player.addComponent(new Health(100));
|
||||
player.addComponent(new PlayerController());
|
||||
|
||||
// 创建敌人
|
||||
for (let i = 0; i < 5; i++) {
|
||||
const enemy = this.createEntity(`Enemy_${i}`);
|
||||
enemy.addComponent(new Position(Math.random() * 800, Math.random() * 600));
|
||||
enemy.addComponent(new Health(50));
|
||||
enemy.addComponent(new EnemyAI());
|
||||
}
|
||||
}
|
||||
|
||||
public onStart(): void {
|
||||
console.log("游戏场景已启动");
|
||||
// 场景启动时的逻辑
|
||||
}
|
||||
|
||||
public unload(): void {
|
||||
console.log("游戏场景已卸载");
|
||||
// 场景卸载时的清理逻辑
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 使用场景配置
|
||||
|
||||
```typescript
|
||||
import { ISceneConfig } from '@esengine/ecs-framework';
|
||||
|
||||
const config: ISceneConfig = {
|
||||
name: "MainGame",
|
||||
enableEntityDirectUpdate: false
|
||||
};
|
||||
|
||||
class ConfiguredScene extends Scene {
|
||||
constructor() {
|
||||
super(config);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 场景生命周期
|
||||
|
||||
场景提供了完整的生命周期管理:
|
||||
|
||||
```typescript
|
||||
class ExampleScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 场景初始化:设置系统和初始实体
|
||||
console.log("场景初始化");
|
||||
}
|
||||
|
||||
public onStart(): void {
|
||||
// 场景开始运行:游戏逻辑开始执行
|
||||
console.log("场景开始运行");
|
||||
}
|
||||
|
||||
public unload(): void {
|
||||
// 场景卸载:清理资源
|
||||
console.log("场景卸载");
|
||||
}
|
||||
}
|
||||
|
||||
// 使用场景(由框架自动管理生命周期)
|
||||
const scene = new ExampleScene();
|
||||
// 场景的 initialize(), begin(), update(), end() 由框架自动调用
|
||||
```
|
||||
|
||||
**生命周期方法**:
|
||||
|
||||
1. `initialize()` - 场景初始化,设置系统和初始实体
|
||||
2. `begin()` / `onStart()` - 场景开始运行
|
||||
3. `update()` - 每帧更新(由场景管理器调用)
|
||||
4. `end()` / `unload()` - 场景卸载,清理资源
|
||||
|
||||
## 实体管理
|
||||
|
||||
### 创建实体
|
||||
|
||||
```typescript
|
||||
class EntityScene extends Scene {
|
||||
createGameEntities(): void {
|
||||
// 创建单个实体
|
||||
const player = this.createEntity("Player");
|
||||
|
||||
// 批量创建实体(高性能)
|
||||
const bullets = this.createEntities(100, "Bullet");
|
||||
|
||||
// 为批量创建的实体添加组件
|
||||
bullets.forEach((bullet, index) => {
|
||||
bullet.addComponent(new Position(index * 10, 100));
|
||||
bullet.addComponent(new Velocity(Math.random() * 200 - 100, -300));
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 查找实体
|
||||
|
||||
```typescript
|
||||
class SearchScene extends Scene {
|
||||
findEntities(): void {
|
||||
// 按名称查找
|
||||
const player = this.findEntity("Player");
|
||||
const player2 = this.getEntityByName("Player"); // 别名方法
|
||||
|
||||
// 按 ID 查找
|
||||
const entity = this.findEntityById(123);
|
||||
|
||||
// 按标签查找
|
||||
const enemies = this.findEntitiesByTag(2);
|
||||
const enemies2 = this.getEntitiesByTag(2); // 别名方法
|
||||
|
||||
if (player) {
|
||||
console.log(`找到玩家: ${player.name}`);
|
||||
}
|
||||
|
||||
console.log(`找到 ${enemies.length} 个敌人`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 销毁实体
|
||||
|
||||
```typescript
|
||||
class DestroyScene extends Scene {
|
||||
cleanupEntities(): void {
|
||||
// 销毁所有实体
|
||||
this.destroyAllEntities();
|
||||
|
||||
// 单个实体的销毁通过实体本身
|
||||
const enemy = this.findEntity("Enemy_1");
|
||||
if (enemy) {
|
||||
enemy.destroy(); // 实体会自动从场景中移除
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 系统管理
|
||||
|
||||
### 添加和移除系统
|
||||
|
||||
```typescript
|
||||
class SystemScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 添加系统
|
||||
const movementSystem = new MovementSystem();
|
||||
this.addSystem(movementSystem);
|
||||
|
||||
// 设置系统更新顺序
|
||||
movementSystem.updateOrder = 1;
|
||||
|
||||
// 添加更多系统
|
||||
this.addSystem(new PhysicsSystem());
|
||||
this.addSystem(new RenderSystem());
|
||||
}
|
||||
|
||||
public removeUnnecessarySystems(): void {
|
||||
// 获取系统
|
||||
const physicsSystem = this.getEntityProcessor(PhysicsSystem);
|
||||
|
||||
// 移除系统
|
||||
if (physicsSystem) {
|
||||
this.removeSystem(physicsSystem);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 系统访问
|
||||
|
||||
```typescript
|
||||
class SystemAccessScene extends Scene {
|
||||
public pausePhysics(): void {
|
||||
const physicsSystem = this.getEntityProcessor(PhysicsSystem);
|
||||
if (physicsSystem) {
|
||||
physicsSystem.enabled = false;
|
||||
}
|
||||
}
|
||||
|
||||
public getAllSystems(): EntitySystem[] {
|
||||
return this.systems; // 获取所有系统
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 事件系统
|
||||
|
||||
场景内置了类型安全的事件系统:
|
||||
|
||||
```typescript
|
||||
class EventScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 监听事件
|
||||
this.eventSystem.on('player_died', this.onPlayerDied.bind(this));
|
||||
this.eventSystem.on('enemy_spawned', this.onEnemySpawned.bind(this));
|
||||
this.eventSystem.on('level_complete', this.onLevelComplete.bind(this));
|
||||
}
|
||||
|
||||
private onPlayerDied(data: any): void {
|
||||
console.log('玩家死亡事件');
|
||||
// 处理玩家死亡
|
||||
}
|
||||
|
||||
private onEnemySpawned(data: any): void {
|
||||
console.log('敌人生成事件');
|
||||
// 处理敌人生成
|
||||
}
|
||||
|
||||
private onLevelComplete(data: any): void {
|
||||
console.log('关卡完成事件');
|
||||
// 处理关卡完成
|
||||
}
|
||||
|
||||
public triggerGameEvent(): void {
|
||||
// 发送事件(同步)
|
||||
this.eventSystem.emitSync('custom_event', {
|
||||
message: "这是自定义事件",
|
||||
timestamp: Date.now()
|
||||
});
|
||||
|
||||
// 发送事件(异步)
|
||||
this.eventSystem.emit('async_event', {
|
||||
data: "异步事件数据"
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 事件系统 API
|
||||
|
||||
```typescript
|
||||
// 监听事件
|
||||
this.eventSystem.on('event_name', callback);
|
||||
|
||||
// 监听一次(自动取消订阅)
|
||||
this.eventSystem.once('event_name', callback);
|
||||
|
||||
// 取消监听
|
||||
this.eventSystem.off('event_name', callback);
|
||||
|
||||
// 同步发送事件
|
||||
this.eventSystem.emitSync('event_name', data);
|
||||
|
||||
// 异步发送事件
|
||||
this.eventSystem.emit('event_name', data);
|
||||
|
||||
// 清除所有事件监听
|
||||
this.eventSystem.clear();
|
||||
```
|
||||
|
||||
## 场景统计和调试
|
||||
|
||||
### 获取场景统计
|
||||
|
||||
```typescript
|
||||
class StatsScene extends Scene {
|
||||
public showStats(): void {
|
||||
const stats = this.getStats();
|
||||
console.log(`实体数量: ${stats.entityCount}`);
|
||||
console.log(`系统数量: ${stats.processorCount}`);
|
||||
console.log('组件存储统计:', stats.componentStorageStats);
|
||||
}
|
||||
|
||||
public showDebugInfo(): void {
|
||||
const debugInfo = this.getDebugInfo();
|
||||
console.log('场景调试信息:', debugInfo);
|
||||
|
||||
// 显示所有实体信息
|
||||
debugInfo.entities.forEach(entity => {
|
||||
console.log(`实体 ${entity.name}(${entity.id}): ${entity.componentCount} 个组件`);
|
||||
console.log('组件类型:', entity.componentTypes);
|
||||
});
|
||||
|
||||
// 显示所有系统信息
|
||||
debugInfo.processors.forEach(processor => {
|
||||
console.log(`系统 ${processor.name}: 处理 ${processor.entityCount} 个实体`);
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 组件查询
|
||||
|
||||
Scene 提供了强大的组件查询系统:
|
||||
|
||||
```typescript
|
||||
class QueryScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 创建一些实体
|
||||
for (let i = 0; i < 10; i++) {
|
||||
const entity = this.createEntity(`Entity_${i}`);
|
||||
entity.addComponent(new Transform(i * 10, 0));
|
||||
entity.addComponent(new Velocity(1, 0));
|
||||
if (i % 2 === 0) {
|
||||
entity.addComponent(new Renderer());
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
public queryEntities(): void {
|
||||
// 通过 QuerySystem 查询
|
||||
const entities = this.querySystem.query([Transform, Velocity]);
|
||||
console.log(`找到 ${entities.length} 个有 Transform 和 Velocity 的实体`);
|
||||
|
||||
// 使用 ECS 流式 API(如果通过 SceneManager)
|
||||
// const api = sceneManager.api;
|
||||
// const entities = api?.find(Transform, Velocity);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 性能监控
|
||||
|
||||
Scene 内置了性能监控功能:
|
||||
|
||||
```typescript
|
||||
class PerformanceScene extends Scene {
|
||||
public showPerformance(): void {
|
||||
// 获取性能数据
|
||||
const perfData = this.performanceMonitor?.getPerformanceData();
|
||||
if (perfData) {
|
||||
console.log('FPS:', perfData.fps);
|
||||
console.log('帧时间:', perfData.frameTime);
|
||||
console.log('实体更新时间:', perfData.entityUpdateTime);
|
||||
console.log('系统更新时间:', perfData.systemUpdateTime);
|
||||
}
|
||||
|
||||
// 获取性能报告
|
||||
const report = this.performanceMonitor?.generateReport();
|
||||
if (report) {
|
||||
console.log('性能报告:', report);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 场景职责分离
|
||||
|
||||
```typescript
|
||||
// 好的场景设计 - 职责清晰
|
||||
class MenuScene extends Scene {
|
||||
// 只处理菜单相关逻辑
|
||||
}
|
||||
|
||||
class GameScene extends Scene {
|
||||
// 只处理游戏玩法逻辑
|
||||
}
|
||||
|
||||
class InventoryScene extends Scene {
|
||||
// 只处理物品栏逻辑
|
||||
}
|
||||
|
||||
// 避免的场景设计 - 职责混乱
|
||||
class MegaScene extends Scene {
|
||||
// 包含菜单、游戏、物品栏等所有逻辑
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 合理的系统组织
|
||||
|
||||
```typescript
|
||||
class OrganizedScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 按功能和依赖关系添加系统
|
||||
this.addInputSystems();
|
||||
this.addLogicSystems();
|
||||
this.addRenderSystems();
|
||||
}
|
||||
|
||||
private addInputSystems(): void {
|
||||
this.addSystem(new InputSystem());
|
||||
}
|
||||
|
||||
private addLogicSystems(): void {
|
||||
this.addSystem(new MovementSystem());
|
||||
this.addSystem(new PhysicsSystem());
|
||||
this.addSystem(new CollisionSystem());
|
||||
}
|
||||
|
||||
private addRenderSystems(): void {
|
||||
this.addSystem(new RenderSystem());
|
||||
this.addSystem(new UISystem());
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 资源管理
|
||||
|
||||
```typescript
|
||||
class ResourceScene extends Scene {
|
||||
private textures: Map<string, any> = new Map();
|
||||
private sounds: Map<string, any> = new Map();
|
||||
|
||||
protected initialize(): void {
|
||||
this.loadResources();
|
||||
}
|
||||
|
||||
private loadResources(): void {
|
||||
// 加载场景所需资源
|
||||
this.textures.set('player', this.loadTexture('player.png'));
|
||||
this.sounds.set('bgm', this.loadSound('bgm.mp3'));
|
||||
}
|
||||
|
||||
public unload(): void {
|
||||
// 清理资源
|
||||
this.textures.clear();
|
||||
this.sounds.clear();
|
||||
console.log('场景资源已清理');
|
||||
}
|
||||
|
||||
private loadTexture(path: string): any {
|
||||
// 加载纹理
|
||||
return null;
|
||||
}
|
||||
|
||||
private loadSound(path: string): any {
|
||||
// 加载音效
|
||||
return null;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 事件处理规范
|
||||
|
||||
```typescript
|
||||
class EventHandlingScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 集中管理事件监听
|
||||
this.setupEventListeners();
|
||||
}
|
||||
|
||||
private setupEventListeners(): void {
|
||||
this.eventSystem.on('game_pause', this.onGamePause.bind(this));
|
||||
this.eventSystem.on('game_resume', this.onGameResume.bind(this));
|
||||
this.eventSystem.on('player_input', this.onPlayerInput.bind(this));
|
||||
}
|
||||
|
||||
private onGamePause(): void {
|
||||
// 暂停游戏逻辑
|
||||
this.systems.forEach(system => {
|
||||
if (system instanceof GameLogicSystem) {
|
||||
system.enabled = false;
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
private onGameResume(): void {
|
||||
// 恢复游戏逻辑
|
||||
this.systems.forEach(system => {
|
||||
if (system instanceof GameLogicSystem) {
|
||||
system.enabled = true;
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
private onPlayerInput(data: any): void {
|
||||
// 处理玩家输入
|
||||
}
|
||||
|
||||
public unload(): void {
|
||||
// 清理事件监听
|
||||
this.eventSystem.clear();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 5. 初始化顺序
|
||||
|
||||
```typescript
|
||||
class ProperInitScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 1. 首先设置场景配置
|
||||
this.name = "GameScene";
|
||||
|
||||
// 2. 然后添加系统(按依赖顺序)
|
||||
this.addSystem(new InputSystem());
|
||||
this.addSystem(new MovementSystem());
|
||||
this.addSystem(new PhysicsSystem());
|
||||
this.addSystem(new RenderSystem());
|
||||
|
||||
// 3. 最后创建实体
|
||||
this.createEntities();
|
||||
|
||||
// 4. 设置事件监听
|
||||
this.setupEvents();
|
||||
}
|
||||
|
||||
private createEntities(): void {
|
||||
// 创建实体
|
||||
}
|
||||
|
||||
private setupEvents(): void {
|
||||
// 设置事件监听
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 完整示例
|
||||
|
||||
```typescript
|
||||
import { Scene, EntitySystem, Entity, Matcher } from '@esengine/ecs-framework';
|
||||
|
||||
// 定义组件
|
||||
class Transform {
|
||||
constructor(public x: number, public y: number) {}
|
||||
}
|
||||
|
||||
class Velocity {
|
||||
constructor(public vx: number, public vy: number) {}
|
||||
}
|
||||
|
||||
class Health {
|
||||
constructor(public value: number) {}
|
||||
}
|
||||
|
||||
// 定义系统
|
||||
class MovementSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(Transform, Velocity));
|
||||
}
|
||||
|
||||
process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const transform = entity.getComponent(Transform);
|
||||
const velocity = entity.getComponent(Velocity);
|
||||
|
||||
if (transform && velocity) {
|
||||
transform.x += velocity.vx;
|
||||
transform.y += velocity.vy;
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// 定义场景
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
this.name = "GameScene";
|
||||
|
||||
// 添加系统
|
||||
this.addSystem(new MovementSystem());
|
||||
|
||||
// 创建玩家
|
||||
const player = this.createEntity("Player");
|
||||
player.addComponent(new Transform(400, 300));
|
||||
player.addComponent(new Velocity(0, 0));
|
||||
player.addComponent(new Health(100));
|
||||
|
||||
// 创建敌人
|
||||
for (let i = 0; i < 5; i++) {
|
||||
const enemy = this.createEntity(`Enemy_${i}`);
|
||||
enemy.addComponent(new Transform(
|
||||
Math.random() * 800,
|
||||
Math.random() * 600
|
||||
));
|
||||
enemy.addComponent(new Velocity(
|
||||
Math.random() * 100 - 50,
|
||||
Math.random() * 100 - 50
|
||||
));
|
||||
enemy.addComponent(new Health(50));
|
||||
}
|
||||
|
||||
// 设置事件监听
|
||||
this.eventSystem.on('player_died', () => {
|
||||
console.log('玩家死亡!');
|
||||
});
|
||||
}
|
||||
|
||||
public onStart(): void {
|
||||
console.log('游戏场景启动');
|
||||
}
|
||||
|
||||
public unload(): void {
|
||||
console.log('游戏场景卸载');
|
||||
this.eventSystem.clear();
|
||||
}
|
||||
}
|
||||
|
||||
// 使用场景
|
||||
// 方式1:通过 SceneManager(推荐)
|
||||
import { Core, SceneManager } from '@esengine/ecs-framework';
|
||||
|
||||
Core.create({ debug: true });
|
||||
const sceneManager = Core.services.resolve(SceneManager);
|
||||
sceneManager.setScene(new GameScene());
|
||||
|
||||
// 方式2:通过 WorldManager(高级用例)
|
||||
import { WorldManager } from '@esengine/ecs-framework';
|
||||
|
||||
const worldManager = Core.services.resolve(WorldManager);
|
||||
const world = worldManager.createWorld('game');
|
||||
world.createScene('main', new GameScene());
|
||||
world.setSceneActive('main', true);
|
||||
```
|
||||
|
||||
## 下一步
|
||||
|
||||
- 了解 [SceneManager](./scene-manager.md) - 适用于大多数游戏的简单场景管理
|
||||
- 了解 [WorldManager](./world-manager.md) - 适用于需要多世界隔离的高级场景
|
||||
|
||||
场景是 ECS 框架的核心容器,正确使用场景管理能让你的游戏架构更加清晰、模块化和易于维护。

# 序列化系统
|
||||
|
||||
序列化系统提供了完整的场景、实体和组件数据持久化方案,支持全量序列化和增量序列化两种模式,适用于游戏存档、网络同步、场景编辑器、时间回溯等场景。
|
||||
|
||||
## 基本概念
|
||||
|
||||
序列化系统分为两个层次:
|
||||
|
||||
- **全量序列化**:序列化完整的场景状态,包括所有实体、组件和场景数据
|
||||
- **增量序列化**:只序列化相对于基础快照的变更部分,大幅减少数据量
|
||||
|
||||
### 支持的数据格式
|
||||
|
||||
- **JSON格式**:人类可读,便于调试和编辑
|
||||
- **Binary格式**:使用MessagePack,体积更小,性能更高
|
||||
|
||||
> **📢 v2.2.2 重要变更**
|
||||
>
|
||||
> 从 v2.2.2 开始,二进制序列化格式返回 `Uint8Array` 而非 Node.js 的 `Buffer`,以确保浏览器兼容性:
|
||||
> - `serialize({ format: 'binary' })` 返回 `string | Uint8Array`(原为 `string | Buffer`)
|
||||
> - `deserialize(data)` 接收 `string | Uint8Array`(原为 `string | Buffer`)
|
||||
> - `applyIncremental(data)` 接收 `IncrementalSnapshot | string | Uint8Array`(原为包含 `Buffer`)
|
||||
>
|
||||
> **迁移影响**:
|
||||
> - ✅ **运行时兼容**:Node.js 的 `Buffer` 继承自 `Uint8Array`,现有代码可直接运行
|
||||
> - ⚠️ **类型检查**:如果你的 TypeScript 代码中显式使用了 `Buffer` 类型,需要改为 `Uint8Array`
|
||||
> - ✅ **浏览器支持**:`Uint8Array` 是标准 JavaScript 类型,所有现代浏览器都支持
|
||||
|
||||
## 全量序列化
|
||||
|
||||
### 基础用法
|
||||
|
||||
#### 1. 标记可序列化组件
|
||||
|
||||
使用 `@Serializable` 和 `@Serialize` 装饰器标记需要序列化的组件和字段:
|
||||
|
||||
```typescript
|
||||
import { Component, ECSComponent, Serializable, Serialize } from '@esengine/ecs-framework';
|
||||
|
||||
@ECSComponent('Player')
|
||||
@Serializable({ version: 1 })
|
||||
class PlayerComponent extends Component {
|
||||
@Serialize()
|
||||
public name: string = '';
|
||||
|
||||
@Serialize()
|
||||
public level: number = 1;
|
||||
|
||||
@Serialize()
|
||||
public experience: number = 0;
|
||||
|
||||
@Serialize()
|
||||
public position: { x: number; y: number } = { x: 0, y: 0 };
|
||||
|
||||
// 不使用 @Serialize() 的字段不会被序列化
|
||||
private tempData: any = null;
|
||||
}
|
||||
```
|
||||
|
||||
#### 2. 序列化场景
|
||||
|
||||
```typescript
|
||||
// JSON格式序列化
|
||||
const jsonData = scene.serialize({
|
||||
format: 'json',
|
||||
pretty: true // 美化输出
|
||||
});
|
||||
|
||||
// 保存到本地存储
|
||||
localStorage.setItem('gameSave', jsonData);
|
||||
|
||||
// Binary格式序列化(更小的体积)
|
||||
const binaryData = scene.serialize({
|
||||
format: 'binary'
|
||||
});
|
||||
|
||||
// 保存为文件(Node.js环境)
|
||||
// 注意:binaryData 是 Uint8Array 类型,Node.js 的 fs 可以直接写入
|
||||
fs.writeFileSync('save.bin', binaryData);
|
||||
```
|
||||
|
||||
#### 3. 反序列化场景
|
||||
|
||||
```typescript
|
||||
// 从JSON恢复
|
||||
const saveData = localStorage.getItem('gameSave');
|
||||
if (saveData) {
|
||||
scene.deserialize(saveData, {
|
||||
strategy: 'replace' // 替换当前场景内容
|
||||
});
|
||||
}
|
||||
|
||||
// 从Binary恢复
|
||||
const binaryData = fs.readFileSync('save.bin');
|
||||
scene.deserialize(binaryData, {
|
||||
strategy: 'merge' // 合并到现有场景
|
||||
});
|
||||
```
|
||||
|
||||
### 序列化选项
|
||||
|
||||
#### SerializationOptions
|
||||
|
||||
```typescript
|
||||
interface SceneSerializationOptions {
|
||||
// 指定要序列化的组件类型(可选)
|
||||
components?: ComponentType[];
|
||||
|
||||
// 序列化格式:'json' 或 'binary'
|
||||
format?: 'json' | 'binary';
|
||||
|
||||
// JSON美化输出
|
||||
pretty?: boolean;
|
||||
|
||||
// 包含元数据
|
||||
includeMetadata?: boolean;
|
||||
}
|
||||
```
|
||||
|
||||
示例:
|
||||
|
||||
```typescript
|
||||
// 只序列化特定组件类型
|
||||
const saveData = scene.serialize({
|
||||
format: 'json',
|
||||
components: [PlayerComponent, InventoryComponent],
|
||||
pretty: true,
|
||||
includeMetadata: true
|
||||
});
|
||||
```
|
||||
|
||||
#### DeserializationOptions
|
||||
|
||||
```typescript
|
||||
interface SceneDeserializationOptions {
|
||||
// 反序列化策略
|
||||
strategy?: 'merge' | 'replace';
|
||||
|
||||
// 组件类型注册表(可选,默认使用全局注册表)
|
||||
componentRegistry?: Map<string, ComponentType>;
|
||||
}
|
||||
```
|
||||
|
||||
### 高级装饰器
|
||||
|
||||
#### 字段序列化选项
|
||||
|
||||
```typescript
|
||||
@ECSComponent('Advanced')
|
||||
@Serializable({ version: 1 })
|
||||
class AdvancedComponent extends Component {
|
||||
// 使用别名
|
||||
@Serialize({ alias: 'playerName' })
|
||||
public name: string = '';
|
||||
|
||||
// 自定义序列化器
|
||||
@Serialize({
|
||||
serializer: (value: Date) => value.toISOString(),
|
||||
deserializer: (value: string) => new Date(value)
|
||||
})
|
||||
public createdAt: Date = new Date();
|
||||
|
||||
// 忽略序列化
|
||||
@IgnoreSerialization()
|
||||
public cachedData: any = null;
|
||||
}
|
||||
```
|
||||
|
||||
#### 集合类型序列化
|
||||
|
||||
```typescript
|
||||
@ECSComponent('Collections')
|
||||
@Serializable({ version: 1 })
|
||||
class CollectionsComponent extends Component {
|
||||
// Map序列化
|
||||
@SerializeAsMap()
|
||||
public inventory: Map<string, number> = new Map();
|
||||
|
||||
// Set序列化
|
||||
@SerializeAsSet()
|
||||
public acquiredSkills: Set<string> = new Set();
|
||||
|
||||
constructor() {
|
||||
super();
|
||||
this.inventory.set('gold', 100);
|
||||
this.inventory.set('silver', 50);
|
||||
this.acquiredSkills.add('attack');
|
||||
this.acquiredSkills.add('defense');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 组件继承与序列化
|
||||
|
||||
框架完整支持组件类的继承,子类会自动继承父类的序列化字段,同时可以添加自己的字段。
|
||||
|
||||
#### 基础继承
|
||||
|
||||
```typescript
|
||||
// 基类组件
|
||||
@ECSComponent('Collider2DBase')
|
||||
@Serializable({ version: 1, typeId: 'Collider2DBase' })
|
||||
abstract class Collider2DBase extends Component {
|
||||
@Serialize()
|
||||
public friction: number = 0.5;
|
||||
|
||||
@Serialize()
|
||||
public restitution: number = 0.0;
|
||||
|
||||
@Serialize()
|
||||
public isTrigger: boolean = false;
|
||||
}
|
||||
|
||||
// 子类组件 - 自动继承父类的序列化字段
|
||||
@ECSComponent('BoxCollider2D')
|
||||
@Serializable({ version: 1, typeId: 'BoxCollider2D' })
|
||||
class BoxCollider2DComponent extends Collider2DBase {
|
||||
@Serialize()
|
||||
public width: number = 1.0;
|
||||
|
||||
@Serialize()
|
||||
public height: number = 1.0;
|
||||
}
|
||||
|
||||
// 另一个子类组件
|
||||
@ECSComponent('CircleCollider2D')
|
||||
@Serializable({ version: 1, typeId: 'CircleCollider2D' })
|
||||
class CircleCollider2DComponent extends Collider2DBase {
|
||||
@Serialize()
|
||||
public radius: number = 0.5;
|
||||
}
|
||||
```
|
||||
|
||||
#### 继承规则
|
||||
|
||||
1. **字段继承**:子类自动继承父类所有被 `@Serialize()` 标记的字段
|
||||
2. **独立元数据**:每个子类维护独立的序列化元数据,修改子类不会影响父类或其他子类
|
||||
3. **typeId 区分**:使用 `typeId` 选项为每个类指定唯一标识,确保反序列化时能正确识别组件类型
|
||||
|
||||
#### 使用 typeId 的重要性
|
||||
|
||||
当使用组件继承时,**强烈建议**为每个类设置唯一的 `typeId`:
|
||||
|
||||
```typescript
|
||||
// ✅ 推荐:明确指定 typeId
|
||||
@Serializable({ version: 1, typeId: 'BoxCollider2D' })
|
||||
class BoxCollider2DComponent extends Collider2DBase { }
|
||||
|
||||
@Serializable({ version: 1, typeId: 'CircleCollider2D' })
|
||||
class CircleCollider2DComponent extends Collider2DBase { }
|
||||
|
||||
// ⚠️ 不推荐:依赖类名作为 typeId
|
||||
// 在代码压缩后类名可能变化,导致反序列化失败
|
||||
@Serializable({ version: 1 })
|
||||
class BoxCollider2DComponent extends Collider2DBase { }
|
||||
```
|
||||
|
||||
#### 子类覆盖父类字段
|
||||
|
||||
子类可以重新声明父类的字段以修改其序列化选项:
|
||||
|
||||
```typescript
|
||||
@ECSComponent('SpecialCollider')
|
||||
@Serializable({ version: 1, typeId: 'SpecialCollider' })
|
||||
class SpecialColliderComponent extends Collider2DBase {
|
||||
// 覆盖父类字段,使用不同的别名
|
||||
@Serialize({ alias: 'fric' })
|
||||
public override friction: number = 0.8;
|
||||
|
||||
@Serialize()
|
||||
public specialProperty: string = '';
|
||||
}
|
||||
```
|
||||
|
||||
#### 忽略继承的字段
|
||||
|
||||
使用 `@IgnoreSerialization()` 可以在子类中忽略从父类继承的字段:
|
||||
|
||||
```typescript
|
||||
@ECSComponent('TriggerOnly')
|
||||
@Serializable({ version: 1, typeId: 'TriggerOnly' })
|
||||
class TriggerOnlyCollider extends Collider2DBase {
|
||||
// 忽略父类的 friction 和 restitution 字段
|
||||
// 因为 Trigger 不需要物理材质属性
|
||||
@IgnoreSerialization()
|
||||
public override friction: number = 0;
|
||||
|
||||
@IgnoreSerialization()
|
||||
public override restitution: number = 0;
|
||||
}
|
||||
```
|
||||
|
||||
### 场景自定义数据
|
||||
|
||||
除了实体和组件,还可以序列化场景级别的配置数据:
|
||||
|
||||
```typescript
|
||||
// 设置场景数据
|
||||
scene.sceneData.set('weather', 'rainy');
|
||||
scene.sceneData.set('difficulty', 'hard');
|
||||
scene.sceneData.set('checkpoint', { x: 100, y: 200 });
|
||||
|
||||
// 序列化时会自动包含场景数据
|
||||
const saveData = scene.serialize({ format: 'json' });
|
||||
|
||||
// 反序列化后场景数据会恢复
|
||||
scene.deserialize(saveData);
|
||||
console.log(scene.sceneData.get('weather')); // 'rainy'
|
||||
```
|
||||
|
||||
## 增量序列化
|
||||
|
||||
增量序列化只保存场景的变更部分,适用于网络同步、撤销/重做、时间回溯等需要频繁保存状态的场景。
|
||||
|
||||
### 基础用法
|
||||
|
||||
#### 1. 创建基础快照
|
||||
|
||||
```typescript
|
||||
// 在需要开始记录变更前创建基础快照
|
||||
scene.createIncrementalSnapshot();
|
||||
```
|
||||
|
||||
#### 2. 修改场景
|
||||
|
||||
```typescript
|
||||
// 添加实体
|
||||
const enemy = scene.createEntity('Enemy');
|
||||
enemy.addComponent(new PositionComponent(100, 200));
|
||||
enemy.addComponent(new HealthComponent(50));
|
||||
|
||||
// 修改组件
|
||||
const player = scene.findEntity('Player');
|
||||
const pos = player.getComponent(PositionComponent);
|
||||
pos.x = 300;
|
||||
pos.y = 400;
|
||||
|
||||
// 删除组件
|
||||
player.removeComponentByType(BuffComponent);
|
||||
|
||||
// 删除实体
|
||||
const oldEntity = scene.findEntity('ToDelete');
|
||||
oldEntity.destroy();
|
||||
|
||||
// 修改场景数据
|
||||
scene.sceneData.set('score', 1000);
|
||||
```
|
||||
|
||||
#### 3. 获取增量变更
|
||||
|
||||
```typescript
|
||||
// 获取相对于基础快照的所有变更
|
||||
const incremental = scene.serializeIncremental();
|
||||
|
||||
// 查看变更统计
|
||||
const stats = IncrementalSerializer.getIncrementalStats(incremental);
|
||||
console.log('总变更数:', stats.totalChanges);
|
||||
console.log('新增实体:', stats.addedEntities);
|
||||
console.log('删除实体:', stats.removedEntities);
|
||||
console.log('新增组件:', stats.addedComponents);
|
||||
console.log('更新组件:', stats.updatedComponents);
|
||||
```
|
||||
|
||||
#### 4. 序列化增量数据
|
||||
|
||||
```typescript
|
||||
// JSON格式(默认)
|
||||
const jsonData = IncrementalSerializer.serializeIncremental(incremental, {
|
||||
format: 'json'
|
||||
});
|
||||
|
||||
// 二进制格式(更小的体积,更高性能)
|
||||
const binaryData = IncrementalSerializer.serializeIncremental(incremental, {
|
||||
format: 'binary'
|
||||
});
|
||||
|
||||
// 美化JSON输出(便于调试)
|
||||
const prettyJson = IncrementalSerializer.serializeIncremental(incremental, {
|
||||
format: 'json',
|
||||
pretty: true
|
||||
});
|
||||
|
||||
// 发送或保存
|
||||
socket.send(binaryData); // 网络传输使用二进制
|
||||
localStorage.setItem('changes', jsonData); // 本地存储可用JSON
|
||||
```
|
||||
|
||||
#### 5. 应用增量变更
|
||||
|
||||
```typescript
|
||||
// 在另一个场景应用变更
|
||||
const otherScene = new Scene();
|
||||
|
||||
// 直接应用增量对象
|
||||
otherScene.applyIncremental(incremental);
|
||||
|
||||
// 从JSON字符串应用
|
||||
const jsonData = IncrementalSerializer.serializeIncremental(incremental, { format: 'json' });
|
||||
otherScene.applyIncremental(jsonData);
|
||||
|
||||
// 从二进制Uint8Array应用
|
||||
const binaryData = IncrementalSerializer.serializeIncremental(incremental, { format: 'binary' });
|
||||
otherScene.applyIncremental(binaryData);
|
||||
```
|
||||
|
||||
### 增量快照管理
|
||||
|
||||
#### 更新快照基准
|
||||
|
||||
在应用增量变更后,可以更新快照基准:
|
||||
|
||||
```typescript
|
||||
// 创建初始快照
|
||||
scene.createIncrementalSnapshot();
|
||||
|
||||
// 第一次修改
|
||||
entity.addComponent(new VelocityComponent(5, 0));
|
||||
const incremental1 = scene.serializeIncremental();
|
||||
|
||||
// 更新基准(将当前状态设为新的基准)
|
||||
scene.updateIncrementalSnapshot();
|
||||
|
||||
// 第二次修改(增量将基于更新后的基准)
|
||||
entity.getComponent(VelocityComponent).dx = 10;
|
||||
const incremental2 = scene.serializeIncremental();
|
||||
```
|
||||
|
||||
#### 清除快照
|
||||
|
||||
```typescript
|
||||
// 释放快照占用的内存
|
||||
scene.clearIncrementalSnapshot();
|
||||
|
||||
// 检查是否有快照
|
||||
if (scene.hasIncrementalSnapshot()) {
|
||||
console.log('存在增量快照');
|
||||
}
|
||||
```
|
||||
|
||||
### 增量序列化选项
|
||||
|
||||
```typescript
|
||||
interface IncrementalSerializationOptions {
|
||||
// 是否进行组件数据的深度对比
|
||||
// 默认true,设为false可提升性能但可能漏掉组件内部字段变更
|
||||
deepComponentComparison?: boolean;
|
||||
|
||||
// 是否跟踪场景数据变更
|
||||
// 默认true
|
||||
trackSceneData?: boolean;
|
||||
|
||||
// 是否压缩快照(使用JSON序列化)
|
||||
// 默认false
|
||||
compressSnapshot?: boolean;
|
||||
|
||||
// 序列化格式
|
||||
// 'json': JSON格式(可读性好,方便调试)
|
||||
// 'binary': MessagePack二进制格式(体积小,性能高)
|
||||
// 默认 'json'
|
||||
format?: 'json' | 'binary';
|
||||
|
||||
// 是否美化JSON输出(仅在format='json'时有效)
|
||||
// 默认false
|
||||
pretty?: boolean;
|
||||
}
|
||||
|
||||
// 使用选项
|
||||
scene.createIncrementalSnapshot({
|
||||
deepComponentComparison: true,
|
||||
trackSceneData: true
|
||||
});
|
||||
```
|
||||
|
||||
### 增量数据结构
|
||||
|
||||
增量快照包含以下变更类型:
|
||||
|
||||
```typescript
|
||||
interface IncrementalSnapshot {
|
||||
version: number; // 快照版本号
|
||||
timestamp: number; // 时间戳
|
||||
sceneName: string; // 场景名称
|
||||
baseVersion: number; // 基础版本号
|
||||
entityChanges: EntityChange[]; // 实体变更
|
||||
componentChanges: ComponentChange[]; // 组件变更
|
||||
sceneDataChanges: SceneDataChange[]; // 场景数据变更
|
||||
}
|
||||
|
||||
// 变更操作类型
|
||||
enum ChangeOperation {
|
||||
EntityAdded = 'entity_added',
|
||||
EntityRemoved = 'entity_removed',
|
||||
EntityUpdated = 'entity_updated',
|
||||
ComponentAdded = 'component_added',
|
||||
ComponentRemoved = 'component_removed',
|
||||
ComponentUpdated = 'component_updated',
|
||||
SceneDataUpdated = 'scene_data_updated'
|
||||
}
|
||||
```
|
||||
|
||||
## 版本迁移
|
||||
|
||||
当组件结构发生变化时,版本迁移系统可以自动升级旧版本的存档数据。
|
||||
|
||||
### 注册迁移函数
|
||||
|
||||
```typescript
|
||||
import { VersionMigrationManager } from '@esengine/ecs-framework';
|
||||
|
||||
// 假设 PlayerComponent v1 有 hp 字段
|
||||
// v2 改为 health 和 maxHealth 字段
|
||||
|
||||
// 注册从版本1到版本2的迁移
|
||||
VersionMigrationManager.registerComponentMigration(
|
||||
'Player',
|
||||
1, // 从版本
|
||||
2, // 到版本
|
||||
(data) => {
|
||||
// 迁移逻辑
|
||||
const newData = {
|
||||
...data,
|
||||
health: data.hp,
|
||||
maxHealth: data.hp,
|
||||
};
|
||||
delete newData.hp;
|
||||
return newData;
|
||||
}
|
||||
);
|
||||
```
|
||||
|
||||
### 使用迁移构建器
|
||||
|
||||
```typescript
|
||||
import { MigrationBuilder } from '@esengine/ecs-framework';
|
||||
|
||||
new MigrationBuilder()
|
||||
.forComponent('Player')
|
||||
.fromVersionToVersion(2, 3)
|
||||
.migrate((data) => {
|
||||
// 从版本2迁移到版本3
|
||||
data.experience = data.exp || 0;
|
||||
delete data.exp;
|
||||
return data;
|
||||
});
|
||||
```
|
||||
|
||||
### 场景级迁移
|
||||
|
||||
```typescript
|
||||
// 注册场景级迁移
|
||||
VersionMigrationManager.registerSceneMigration(
|
||||
1, // 从版本
|
||||
2, // 到版本
|
||||
(scene) => {
|
||||
// 迁移场景结构
|
||||
scene.metadata = {
|
||||
...scene.metadata,
|
||||
migratedFrom: 1
|
||||
};
|
||||
return scene;
|
||||
}
|
||||
);
|
||||
```
|
||||
|
||||
### 检查迁移路径
|
||||
|
||||
```typescript
|
||||
// 检查是否可以迁移
|
||||
const canMigrate = VersionMigrationManager.canMigrateComponent(
|
||||
'Player',
|
||||
1, // 从版本
|
||||
3 // 到版本
|
||||
);
|
||||
|
||||
if (canMigrate) {
|
||||
// 可以安全迁移
|
||||
scene.deserialize(oldSaveData);
|
||||
}
|
||||
|
||||
// 获取迁移路径
|
||||
const path = VersionMigrationManager.getComponentMigrationPath('Player');
|
||||
console.log('可用迁移版本:', path); // [1, 2, 3]
|
||||
```
|
||||
|
||||
## 使用场景
|
||||
|
||||
### 游戏存档系统
|
||||
|
||||
```typescript
|
||||
class SaveSystem {
|
||||
private static SAVE_KEY = 'game_save';
|
||||
|
||||
// 保存游戏
|
||||
public static saveGame(scene: Scene): void {
|
||||
const saveData = scene.serialize({
|
||||
format: 'json',
|
||||
pretty: false
|
||||
});
|
||||
|
||||
localStorage.setItem(this.SAVE_KEY, saveData);
|
||||
console.log('游戏已保存');
|
||||
}
|
||||
|
||||
// 加载游戏
|
||||
public static loadGame(scene: Scene): boolean {
|
||||
const saveData = localStorage.getItem(this.SAVE_KEY);
|
||||
if (saveData) {
|
||||
scene.deserialize(saveData, {
|
||||
strategy: 'replace'
|
||||
});
|
||||
console.log('游戏已加载');
|
||||
return true;
|
||||
}
|
||||
return false;
|
||||
}
|
||||
|
||||
// 检查是否有存档
|
||||
public static hasSave(): boolean {
|
||||
return localStorage.getItem(this.SAVE_KEY) !== null;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 网络同步
|
||||
|
||||
```typescript
|
||||
class NetworkSync {
|
||||
private baseSnapshot?: any;
|
||||
private syncInterval: number = 100; // 100ms同步一次
|
||||
|
||||
constructor(private scene: Scene, private socket: WebSocket) {
|
||||
this.setupSync();
|
||||
}
|
||||
|
||||
private setupSync(): void {
|
||||
// 创建基础快照
|
||||
this.scene.createIncrementalSnapshot();
|
||||
|
||||
// 定期发送增量
|
||||
setInterval(() => {
|
||||
this.sendIncremental();
|
||||
}, this.syncInterval);
|
||||
|
||||
// 接收远程增量
|
||||
this.socket.onmessage = (event) => {
|
||||
this.receiveIncremental(event.data);
|
||||
};
|
||||
}
|
||||
|
||||
private sendIncremental(): void {
|
||||
const incremental = this.scene.serializeIncremental();
|
||||
const stats = IncrementalSerializer.getIncrementalStats(incremental);
|
||||
|
||||
// 只在有变更时发送
|
||||
if (stats.totalChanges > 0) {
|
||||
// 使用二进制格式减少网络传输量
|
||||
const binaryData = IncrementalSerializer.serializeIncremental(incremental, {
|
||||
format: 'binary'
|
||||
});
|
||||
this.socket.send(binaryData);
|
||||
|
||||
// 更新基准
|
||||
this.scene.updateIncrementalSnapshot();
|
||||
}
|
||||
}
|
||||
|
||||
private receiveIncremental(data: ArrayBuffer): void {
|
||||
// 直接应用二进制数据(ArrayBuffer 转 Uint8Array)
|
||||
const uint8Array = new Uint8Array(data);
|
||||
this.scene.applyIncremental(uint8Array);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 撤销/重做系统
|
||||
|
||||
```typescript
|
||||
class UndoRedoSystem {
|
||||
private history: IncrementalSnapshot[] = [];
|
||||
private currentIndex: number = -1;
|
||||
private maxHistory: number = 50;
|
||||
|
||||
constructor(private scene: Scene) {
|
||||
// 创建初始快照
|
||||
this.scene.createIncrementalSnapshot();
|
||||
this.saveState('Initial');
|
||||
}
|
||||
|
||||
// 保存当前状态
|
||||
public saveState(label: string): void {
|
||||
const incremental = this.scene.serializeIncremental();
|
||||
|
||||
// 删除当前位置之后的历史
|
||||
this.history = this.history.slice(0, this.currentIndex + 1);
|
||||
|
||||
// 添加新状态
|
||||
this.history.push(incremental);
|
||||
this.currentIndex++;
|
||||
|
||||
// 限制历史记录数量
|
||||
if (this.history.length > this.maxHistory) {
|
||||
this.history.shift();
|
||||
this.currentIndex--;
|
||||
}
|
||||
|
||||
// 更新快照基准
|
||||
this.scene.updateIncrementalSnapshot();
|
||||
}
|
||||
|
||||
// 撤销
|
||||
public undo(): boolean {
|
||||
if (this.currentIndex > 0) {
|
||||
this.currentIndex--;
|
||||
const incremental = this.history[this.currentIndex];
|
||||
this.scene.applyIncremental(incremental);
|
||||
return true;
|
||||
}
|
||||
return false;
|
||||
}
|
||||
|
||||
// 重做
|
||||
public redo(): boolean {
|
||||
if (this.currentIndex < this.history.length - 1) {
|
||||
this.currentIndex++;
|
||||
const incremental = this.history[this.currentIndex];
|
||||
this.scene.applyIncremental(incremental);
|
||||
return true;
|
||||
}
|
||||
return false;
|
||||
}
|
||||
|
||||
public canUndo(): boolean {
|
||||
return this.currentIndex > 0;
|
||||
}
|
||||
|
||||
public canRedo(): boolean {
|
||||
return this.currentIndex < this.history.length - 1;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 关卡编辑器
|
||||
|
||||
```typescript
|
||||
class LevelEditor {
|
||||
// 导出关卡
|
||||
public exportLevel(scene: Scene, filename: string): void {
|
||||
const levelData = scene.serialize({
|
||||
format: 'json',
|
||||
pretty: true,
|
||||
includeMetadata: true
|
||||
});
|
||||
|
||||
// 浏览器环境
|
||||
const blob = new Blob([levelData], { type: 'application/json' });
|
||||
const url = URL.createObjectURL(blob);
|
||||
const a = document.createElement('a');
|
||||
a.href = url;
|
||||
a.download = filename;
|
||||
a.click();
|
||||
URL.revokeObjectURL(url);
|
||||
}
|
||||
|
||||
// 导入关卡
|
||||
public importLevel(scene: Scene, fileContent: string): void {
|
||||
scene.deserialize(fileContent, {
|
||||
strategy: 'replace'
|
||||
});
|
||||
}
|
||||
|
||||
// 验证关卡数据
|
||||
public validateLevel(saveData: string): boolean {
|
||||
const validation = SceneSerializer.validate(saveData);
|
||||
if (!validation.valid) {
|
||||
console.error('关卡数据无效:', validation.errors);
|
||||
return false;
|
||||
}
|
||||
return true;
|
||||
}
|
||||
|
||||
// 获取关卡信息(不完全反序列化)
|
||||
public getLevelInfo(saveData: string): any {
|
||||
const info = SceneSerializer.getInfo(saveData);
|
||||
return info;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 性能优化建议
|
||||
|
||||
### 1. 选择合适的格式
|
||||
|
||||
- **开发阶段**:使用JSON格式,便于调试和查看
|
||||
- **生产环境**:使用Binary格式,减少30-50%的数据大小
|
||||
|
||||
### 2. 按需序列化
|
||||
|
||||
```typescript
|
||||
// 只序列化需要持久化的组件
|
||||
const saveData = scene.serialize({
|
||||
format: 'binary',
|
||||
components: [PlayerComponent, InventoryComponent, QuestComponent]
|
||||
});
|
||||
```
|
||||
|
||||
### 3. 增量序列化优化
|
||||
|
||||
```typescript
|
||||
// 对于高频同步,关闭深度对比以提升性能
|
||||
scene.createIncrementalSnapshot({
|
||||
deepComponentComparison: false // 只检测组件的添加/删除
|
||||
});
|
||||
```
|
||||
|
||||
### 4. 批量操作
|
||||
|
||||
```typescript
|
||||
// 批量修改后再序列化
|
||||
scene.entities.buffer.forEach(entity => {
|
||||
// 批量修改
|
||||
});
|
||||
|
||||
// 一次性序列化所有变更
|
||||
const incremental = scene.serializeIncremental();
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 明确序列化字段
|
||||
|
||||
```typescript
|
||||
// 明确标记需要序列化的字段
|
||||
@ECSComponent('Player')
|
||||
@Serializable({ version: 1 })
|
||||
class PlayerComponent extends Component {
|
||||
@Serialize()
|
||||
public name: string = '';
|
||||
|
||||
@Serialize()
|
||||
public level: number = 1;
|
||||
|
||||
// 运行时数据不序列化
|
||||
private _cachedSprite: any = null;
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 使用版本控制
|
||||
|
||||
```typescript
|
||||
// 为组件指定版本
|
||||
@Serializable({ version: 2 })
|
||||
class PlayerComponent extends Component {
|
||||
// 版本2的字段
|
||||
}
|
||||
|
||||
// 注册迁移函数确保兼容性
|
||||
VersionMigrationManager.registerComponentMigration('Player', 1, 2, migrateV1ToV2);
|
||||
```
|
||||
|
||||
### 3. 避免循环引用
|
||||
|
||||
```typescript
|
||||
// 不要在组件中直接引用其他实体
|
||||
@ECSComponent('Follower')
|
||||
@Serializable({ version: 1 })
|
||||
class FollowerComponent extends Component {
|
||||
// 存储实体ID而不是实体引用
|
||||
@Serialize()
|
||||
public targetId: number = 0;
|
||||
|
||||
// 通过场景查找目标实体
|
||||
public getTarget(scene: Scene): Entity | null {
|
||||
return scene.entities.findEntityById(this.targetId);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 压缩大数据
|
||||
|
||||
```typescript
|
||||
// 对于大型数据结构,使用自定义序列化
|
||||
@ECSComponent('LargeData')
|
||||
@Serializable({ version: 1 })
|
||||
class LargeDataComponent extends Component {
|
||||
@Serialize({
|
||||
serializer: (data: LargeObject) => compressData(data),
|
||||
deserializer: (data: CompressedData) => decompressData(data)
|
||||
})
|
||||
public data: LargeObject;
|
||||
}
|
||||
```
|
||||
|
||||

# 服务容器
|
||||
|
||||
服务容器(ServiceContainer)是 ECS Framework 的依赖注入容器,负责管理框架中所有服务的注册、解析和生命周期。通过服务容器,你可以实现松耦合的架构设计,提高代码的可测试性和可维护性。
|
||||
|
||||
## 概述
|
||||
|
||||
### 什么是服务容器
|
||||
|
||||
服务容器是一个轻量级的依赖注入(DI)容器,它提供了:
|
||||
|
||||
- **服务注册**: 将服务类型注册到容器中
|
||||
- **服务解析**: 从容器中获取服务实例
|
||||
- **生命周期管理**: 自动管理服务实例的创建和销毁
|
||||
- **依赖注入**: 自动解析服务之间的依赖关系
|
||||
|
||||
### 核心概念
|
||||
|
||||
#### 服务(Service)
|
||||
|
||||
服务是实现了 `IService` 接口的类,必须提供 `dispose()` 方法用于资源清理:
|
||||
|
||||
```typescript
|
||||
import { IService } from '@esengine/ecs-framework';
|
||||
|
||||
class MyService implements IService {
|
||||
constructor() {
|
||||
// 初始化逻辑
|
||||
}
|
||||
|
||||
dispose(): void {
|
||||
// 清理资源
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 服务标识符(ServiceIdentifier)
|
||||
|
||||
服务标识符用于在容器中唯一标识一个服务,支持两种类型:
|
||||
|
||||
- **类构造函数**: 直接使用服务类作为标识符,适用于具体实现类
|
||||
- **Symbol**: 使用 Symbol 作为标识符,适用于接口抽象(推荐用于插件和跨包场景)
|
||||
|
||||
```typescript
|
||||
// 方式1: 使用类作为标识符
|
||||
Core.services.registerSingleton(DataService);
|
||||
const data = Core.services.resolve(DataService);
|
||||
|
||||
// 方式2: 使用 Symbol 作为标识符(推荐用于接口)
|
||||
const IFileSystem = Symbol.for('IFileSystem');
|
||||
Core.services.registerInstance(IFileSystem, new TauriFileSystem());
|
||||
const fs = Core.services.resolve<IFileSystem>(IFileSystem);
|
||||
```
|
||||
|
||||
> **提示**: 使用 `Symbol.for()` 而非 `Symbol()` 可确保跨包/跨模块共享同一个标识符。详见[高级用法 - 接口与 Symbol 标识符模式](#接口与-symbol-标识符模式)。
|
||||
|
||||
#### 生命周期
|
||||
|
||||
服务容器支持两种生命周期:
|
||||
|
||||
- **Singleton(单例)**: 整个应用程序生命周期内只有一个实例,所有解析请求返回同一个实例
|
||||
- **Transient(瞬时)**: 每次解析都创建新的实例
|
||||
|
||||
## 基础使用
|
||||
|
||||
### 访问服务容器
|
||||
|
||||
ECS Framework 提供了三级服务容器:
|
||||
|
||||
> **版本说明**:World 服务容器功能在 v2.2.13+ 版本中可用
|
||||
|
||||
#### Core 级别服务容器
|
||||
|
||||
应用程序全局服务容器,可以通过 `Core.services` 访问:
|
||||
|
||||
```typescript
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
|
||||
// 初始化Core
|
||||
Core.create({ debug: true });
|
||||
|
||||
// 访问全局服务容器
|
||||
const container = Core.services;
|
||||
```
|
||||
|
||||
#### World 级别服务容器
|
||||
|
||||
每个 World 拥有独立的服务容器,用于管理 World 范围内的服务:
|
||||
|
||||
```typescript
|
||||
import { World } from '@esengine/ecs-framework';
|
||||
|
||||
// 创建 World
|
||||
const world = new World({ name: 'GameWorld' });
|
||||
|
||||
// 访问 World 级别的服务容器
|
||||
const worldContainer = world.services;
|
||||
|
||||
// 注册 World 级别的服务
|
||||
world.services.registerSingleton(RoomManager);
|
||||
```
|
||||
|
||||
#### Scene 级别服务容器
|
||||
|
||||
每个 Scene 拥有独立的服务容器,用于管理 Scene 范围内的服务:
|
||||
|
||||
```typescript
|
||||
// 访问 Scene 级别的服务容器
|
||||
const sceneContainer = scene.services;
|
||||
|
||||
// 注册 Scene 级别的服务
|
||||
scene.services.registerSingleton(PhysicsSystem);
|
||||
```
|
||||
|
||||
#### 服务容器层级
|
||||
|
||||
```
|
||||
Core.services (应用程序全局)
|
||||
└─ World.services (World 级别)
|
||||
└─ Scene.services (Scene 级别)
|
||||
```
|
||||
|
||||
不同级别的服务容器是独立的,服务不会自动向上或向下查找。选择合适的容器级别:
|
||||
|
||||
- **Core.services**: 应用程序级别的全局服务(配置、插件管理器等)
|
||||
- **World.services**: World 级别的服务(房间管理器、多人游戏状态等)
|
||||
- **Scene.services**: Scene 级别的服务(ECS 系统、场景特定逻辑等)
|
||||
|
||||
### 注册服务
|
||||
|
||||
#### 注册单例服务
|
||||
|
||||
单例服务在首次解析时创建,之后所有解析请求都返回同一个实例:
|
||||
|
||||
```typescript
|
||||
class DataService implements IService {
|
||||
private data: Map<string, any> = new Map();
|
||||
|
||||
getData(key: string) {
|
||||
return this.data.get(key);
|
||||
}
|
||||
|
||||
setData(key: string, value: any) {
|
||||
this.data.set(key, value);
|
||||
}
|
||||
|
||||
dispose(): void {
|
||||
this.data.clear();
|
||||
}
|
||||
}
|
||||
|
||||
// 注册单例服务
|
||||
Core.services.registerSingleton(DataService);
|
||||
```
|
||||
|
||||
#### 注册瞬时服务
|
||||
|
||||
瞬时服务每次解析都创建新实例,适用于无状态或短生命周期的服务:
|
||||
|
||||
```typescript
|
||||
class CommandService implements IService {
|
||||
execute(command: string) {
|
||||
console.log(`Executing: ${command}`);
|
||||
}
|
||||
|
||||
dispose(): void {
|
||||
// 清理资源
|
||||
}
|
||||
}
|
||||
|
||||
// 注册瞬时服务
|
||||
Core.services.registerTransient(CommandService);
|
||||
```
|
||||
|
||||
#### 注册服务实例
|
||||
|
||||
直接注册已创建的实例,自动视为单例:
|
||||
|
||||
```typescript
|
||||
const config = new ConfigService();
|
||||
config.load('./config.json');
|
||||
|
||||
// 注册实例
|
||||
Core.services.registerInstance(ConfigService, config);
|
||||
```
|
||||
|
||||
#### 使用工厂函数注册
|
||||
|
||||
工厂函数允许你在创建服务时执行自定义逻辑:
|
||||
|
||||
```typescript
|
||||
Core.services.registerSingleton(LoggerService, (container) => {
|
||||
const logger = new LoggerService();
|
||||
logger.setLevel('debug');
|
||||
return logger;
|
||||
});
|
||||
```
|
||||
|
||||
### 解析服务
|
||||
|
||||
#### resolve 方法
|
||||
|
||||
解析服务实例,如果服务未注册会抛出异常:
|
||||
|
||||
```typescript
|
||||
// 解析服务
|
||||
const dataService = Core.services.resolve(DataService);
|
||||
dataService.setData('player', { name: 'Alice', score: 100 });
|
||||
|
||||
// 单例服务,多次解析返回同一个实例
|
||||
const same = Core.services.resolve(DataService);
|
||||
console.log(same === dataService); // true
|
||||
```
|
||||
|
||||
#### tryResolve 方法
|
||||
|
||||
尝试解析服务,如果未注册返回 null 而不抛出异常:
|
||||
|
||||
```typescript
|
||||
const optional = Core.services.tryResolve(OptionalService);
|
||||
if (optional) {
|
||||
optional.doSomething();
|
||||
}
|
||||
```
|
||||
|
||||
#### isRegistered 方法
|
||||
|
||||
检查服务是否已注册:
|
||||
|
||||
```typescript
|
||||
if (Core.services.isRegistered(DataService)) {
|
||||
const service = Core.services.resolve(DataService);
|
||||
}
|
||||
```
|
||||
|
||||
## 内置服务
|
||||
|
||||
Core 在初始化时自动注册了以下内置服务:
|
||||
|
||||
### TimerManager
|
||||
|
||||
定时器管理器,负责管理所有游戏定时器:
|
||||
|
||||
```typescript
|
||||
const timerManager = Core.services.resolve(TimerManager);
|
||||
|
||||
// 创建定时器
|
||||
timerManager.schedule(1.0, false, null, (timer) => {
|
||||
console.log('1秒后执行');
|
||||
});
|
||||
```
|
||||
|
||||
### PerformanceMonitor
|
||||
|
||||
性能监控器,监控游戏性能并提供优化建议:
|
||||
|
||||
```typescript
|
||||
const monitor = Core.services.resolve(PerformanceMonitor);
|
||||
|
||||
// 启用性能监控
|
||||
monitor.enable();
|
||||
|
||||
// 获取性能数据
|
||||
const fps = monitor.getFPS();
|
||||
```
|
||||
|
||||
### SceneManager
|
||||
|
||||
场景管理器,管理单场景应用的场景生命周期:
|
||||
|
||||
```typescript
|
||||
const sceneManager = Core.services.resolve(SceneManager);
|
||||
|
||||
// 设置当前场景
|
||||
sceneManager.setScene(new GameScene());
|
||||
|
||||
// 获取当前场景
|
||||
const currentScene = sceneManager.currentScene;
|
||||
|
||||
// 延迟切换场景
|
||||
sceneManager.loadScene(new MenuScene());
|
||||
|
||||
// 更新场景
|
||||
sceneManager.update();
|
||||
```
|
||||
|
||||
### WorldManager
|
||||
|
||||
世界管理器,管理多个独立的 World 实例(高级用例):
|
||||
|
||||
```typescript
|
||||
const worldManager = Core.services.resolve(WorldManager);
|
||||
|
||||
// 创建独立的游戏世界
|
||||
const gameWorld = worldManager.createWorld('game_room_001', {
|
||||
name: 'GameRoom',
|
||||
maxScenes: 5
|
||||
});
|
||||
|
||||
// 在World中创建场景
|
||||
const scene = gameWorld.createScene('battle', new BattleScene());
|
||||
gameWorld.setSceneActive('battle', true);
|
||||
|
||||
// 更新所有World
|
||||
worldManager.updateAll();
|
||||
```
|
||||
|
||||
**适用场景**:
|
||||
- SceneManager: 适用于 95% 的游戏(单人游戏、简单多人游戏)
|
||||
- WorldManager: 适用于 MMO 服务器、游戏房间系统等需要完全隔离的多世界应用
|
||||
|
||||
### PoolManager
|
||||
|
||||
对象池管理器,管理所有对象池:
|
||||
|
||||
```typescript
|
||||
const poolManager = Core.services.resolve(PoolManager);
|
||||
|
||||
// 创建对象池
|
||||
const bulletPool = poolManager.createPool('bullets', () => new Bullet(), 100);
|
||||
```
|
||||
|
||||
### PluginManager
|
||||
|
||||
插件管理器,管理插件的安装和卸载:
|
||||
|
||||
```typescript
|
||||
const pluginManager = Core.services.resolve(PluginManager);
|
||||
|
||||
// 获取所有已安装的插件
|
||||
const plugins = pluginManager.getAllPlugins();
|
||||
```
|
||||
|
||||
## 依赖注入
|
||||
|
||||
ECS Framework 提供了装饰器来简化依赖注入。
|
||||
|
||||
### @Injectable 装饰器
|
||||
|
||||
标记类为可注入的服务:
|
||||
|
||||
```typescript
|
||||
import { Injectable, IService } from '@esengine/ecs-framework';
|
||||
|
||||
@Injectable()
|
||||
class GameService implements IService {
|
||||
constructor() {
|
||||
console.log('GameService created');
|
||||
}
|
||||
|
||||
dispose(): void {
|
||||
console.log('GameService disposed');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### @InjectProperty 装饰器
|
||||
|
||||
通过属性装饰器注入依赖。注入时机是在构造函数执行后、`onInitialize()` 调用前完成:
|
||||
|
||||
```typescript
|
||||
import { Injectable, InjectProperty, IService } from '@esengine/ecs-framework';
|
||||
|
||||
@Injectable()
|
||||
class PlayerService implements IService {
|
||||
@InjectProperty(DataService)
|
||||
private data!: DataService;
|
||||
|
||||
@InjectProperty(GameService)
|
||||
private game!: GameService;
|
||||
|
||||
dispose(): void {
|
||||
// 清理资源
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
在 EntitySystem 中使用属性注入:
|
||||
|
||||
```typescript
|
||||
@Injectable()
|
||||
class CombatSystem extends EntitySystem {
|
||||
@InjectProperty(TimeService)
|
||||
private timeService!: TimeService;
|
||||
|
||||
@InjectProperty(AudioService)
|
||||
private audio!: AudioService;
|
||||
|
||||
constructor() {
|
||||
super(Matcher.all(Health, Attack));
|
||||
}
|
||||
|
||||
onInitialize(): void {
|
||||
// 此时属性已注入完成,可以安全使用
|
||||
console.log('Delta time:', this.timeService.getDeltaTime());
|
||||
}
|
||||
|
||||
processEntity(entity: Entity): void {
|
||||
// 使用注入的服务
|
||||
this.audio.playSound('attack');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
> **注意**: 属性声明时使用 `!` 断言(如 `private data!: DataService`),表示该属性会在使用前被注入。
|
||||
|
||||
### 注册可注入服务
|
||||
|
||||
使用 `registerInjectable` 自动处理依赖注入:
|
||||
|
||||
```typescript
|
||||
import { registerInjectable } from '@esengine/ecs-framework';
|
||||
|
||||
// 注册服务(会自动解析 @InjectProperty 依赖)
|
||||
registerInjectable(Core.services, PlayerService);
|
||||
|
||||
// 解析时会自动注入属性依赖
|
||||
const player = Core.services.resolve(PlayerService);
|
||||
```
|
||||
|
||||
### @Updatable 装饰器
|
||||
|
||||
标记服务为可更新的,使其在每帧自动被调用:
|
||||
|
||||
```typescript
|
||||
import { Injectable, Updatable, IService, IUpdatable } from '@esengine/ecs-framework';
|
||||
|
||||
@Injectable()
|
||||
@Updatable() // 默认优先级为0
|
||||
class PhysicsService implements IService, IUpdatable {
|
||||
update(deltaTime?: number): void {
|
||||
// 每帧更新物理模拟
|
||||
}
|
||||
|
||||
dispose(): void {
|
||||
// 清理资源
|
||||
}
|
||||
}
|
||||
|
||||
// 指定更新优先级(数值越小越先执行)
|
||||
@Injectable()
|
||||
@Updatable(10)
|
||||
class RenderService implements IService, IUpdatable {
|
||||
update(deltaTime?: number): void {
|
||||
// 每帧渲染
|
||||
}
|
||||
|
||||
dispose(): void {
|
||||
// 清理资源
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
使用 `@Updatable` 装饰器的服务会被 Core 自动调用,无需手动管理:
|
||||
|
||||
```typescript
|
||||
// Core.update() 会自动调用所有@Updatable服务的update方法
|
||||
function gameLoop(deltaTime: number) {
|
||||
Core.update(deltaTime); // 自动更新所有可更新服务
|
||||
}
|
||||
```
|
||||
|
||||
## 自定义服务
|
||||
|
||||
### 创建自定义服务
|
||||
|
||||
实现 `IService` 接口并注册到容器:
|
||||
|
||||
```typescript
|
||||
import { IService } from '@esengine/ecs-framework';
|
||||
|
||||
class AudioService implements IService {
|
||||
private sounds: Map<string, HTMLAudioElement> = new Map();
|
||||
|
||||
play(soundId: string) {
|
||||
const sound = this.sounds.get(soundId);
|
||||
if (sound) {
|
||||
sound.play();
|
||||
}
|
||||
}
|
||||
|
||||
load(soundId: string, url: string) {
|
||||
const audio = new Audio(url);
|
||||
this.sounds.set(soundId, audio);
|
||||
}
|
||||
|
||||
dispose(): void {
|
||||
// 停止所有音效并清理
|
||||
for (const sound of this.sounds.values()) {
|
||||
sound.pause();
|
||||
sound.src = '';
|
||||
}
|
||||
this.sounds.clear();
|
||||
}
|
||||
}
|
||||
|
||||
// 注册自定义服务
|
||||
Core.services.registerSingleton(AudioService);
|
||||
|
||||
// 使用服务
|
||||
const audio = Core.services.resolve(AudioService);
|
||||
audio.load('jump', '/sounds/jump.mp3');
|
||||
audio.play('jump');
|
||||
```
|
||||
|
||||
### 服务间依赖
|
||||
|
||||
服务可以依赖其他服务:
|
||||
|
||||
```typescript
|
||||
@Injectable()
|
||||
class ConfigService implements IService {
|
||||
private config: any = {};
|
||||
|
||||
get(key: string) {
|
||||
return this.config[key];
|
||||
}
|
||||
|
||||
dispose(): void {
|
||||
this.config = {};
|
||||
}
|
||||
}
|
||||
|
||||
@Injectable()
|
||||
class NetworkService implements IService {
|
||||
constructor(
|
||||
@Inject(ConfigService) private config: ConfigService
|
||||
) {
|
||||
// 使用配置服务
|
||||
const apiUrl = this.config.get('apiUrl');
|
||||
}
|
||||
|
||||
dispose(): void {
|
||||
// 清理网络连接
|
||||
}
|
||||
}
|
||||
|
||||
// 注册服务(按依赖顺序)
|
||||
registerInjectable(Core.services, ConfigService);
|
||||
registerInjectable(Core.services, NetworkService);
|
||||
```
|
||||
|
||||
## 高级用法
|
||||
|
||||
### 接口与 Symbol 标识符模式
|
||||
|
||||
在大型项目或需要跨平台适配的游戏中,推荐使用"接口 + Symbol.for 标识符"模式。这种模式实现了真正的依赖倒置,让代码依赖于抽象而非具体实现。
|
||||
|
||||
#### 为什么使用 Symbol.for
|
||||
|
||||
- **跨包共享**: `Symbol.for('key')` 在全局 Symbol 注册表中创建/获取 Symbol,确保不同包中使用相同的标识符
|
||||
- **接口解耦**: 消费者只依赖接口定义,不依赖具体实现类
|
||||
- **可替换实现**: 可以在运行时注入不同的实现(如测试 Mock、不同平台适配)
|
||||
|
||||
#### 定义接口和标识符
|
||||
|
||||
以音频服务为例,游戏需要在不同平台(Web、微信小游戏、原生App)使用不同的音频实现:
|
||||
|
||||
```typescript
|
||||
// IAudioService.ts - 定义接口和标识符
|
||||
export interface IAudioService {
|
||||
dispose(): void;
|
||||
playSound(id: string): void;
|
||||
playMusic(id: string, loop?: boolean): void;
|
||||
stopMusic(): void;
|
||||
setVolume(volume: number): void;
|
||||
preload(id: string, url: string): Promise<void>;
|
||||
}
|
||||
|
||||
// 使用 Symbol.for 确保跨包共享同一个 Symbol
|
||||
export const IAudioService = Symbol.for('IAudioService');
|
||||
```
|
||||
|
||||
#### 实现接口
|
||||
|
||||
```typescript
|
||||
// WebAudioService.ts - Web 平台实现
|
||||
import { IAudioService } from './IAudioService';
|
||||
|
||||
export class WebAudioService implements IAudioService {
|
||||
private audioContext: AudioContext;
|
||||
private sounds: Map<string, AudioBuffer> = new Map();
|
||||
|
||||
constructor() {
|
||||
this.audioContext = new AudioContext();
|
||||
}
|
||||
|
||||
playSound(id: string): void {
|
||||
const buffer = this.sounds.get(id);
|
||||
if (buffer) {
|
||||
const source = this.audioContext.createBufferSource();
|
||||
source.buffer = buffer;
|
||||
source.connect(this.audioContext.destination);
|
||||
source.start();
|
||||
}
|
||||
}
|
||||
|
||||
async preload(id: string, url: string): Promise<void> {
|
||||
const response = await fetch(url);
|
||||
const arrayBuffer = await response.arrayBuffer();
|
||||
const audioBuffer = await this.audioContext.decodeAudioData(arrayBuffer);
|
||||
this.sounds.set(id, audioBuffer);
|
||||
}
|
||||
|
||||
// ... 其他方法实现
|
||||
|
||||
dispose(): void {
|
||||
this.audioContext.close();
|
||||
this.sounds.clear();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```typescript
|
||||
// WechatAudioService.ts - 微信小游戏平台实现
|
||||
export class WechatAudioService implements IAudioService {
|
||||
private innerAudioContexts: Map<string, WechatMinigame.InnerAudioContext> = new Map();
|
||||
|
||||
playSound(id: string): void {
|
||||
const ctx = this.innerAudioContexts.get(id);
|
||||
if (ctx) {
|
||||
ctx.play();
|
||||
}
|
||||
}
|
||||
|
||||
async preload(id: string, url: string): Promise<void> {
|
||||
const ctx = wx.createInnerAudioContext();
|
||||
ctx.src = url;
|
||||
this.innerAudioContexts.set(id, ctx);
|
||||
}
|
||||
|
||||
// ... 其他方法实现
|
||||
|
||||
dispose(): void {
|
||||
for (const ctx of this.innerAudioContexts.values()) {
|
||||
ctx.destroy();
|
||||
}
|
||||
this.innerAudioContexts.clear();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 注册和使用
|
||||
|
||||
```typescript
|
||||
import { IAudioService } from './IAudioService';
|
||||
import { WebAudioService } from './WebAudioService';
|
||||
import { WechatAudioService } from './WechatAudioService';
|
||||
|
||||
// 根据平台注册不同实现
|
||||
if (typeof wx !== 'undefined') {
|
||||
Core.services.registerInstance(IAudioService, new WechatAudioService());
|
||||
} else {
|
||||
Core.services.registerInstance(IAudioService, new WebAudioService());
|
||||
}
|
||||
|
||||
// 业务代码中使用 - 不关心具体实现
|
||||
const audio = Core.services.resolve<IAudioService>(IAudioService);
|
||||
await audio.preload('explosion', '/sounds/explosion.mp3');
|
||||
audio.playSound('explosion');
|
||||
```
|
||||
|
||||
#### 跨模块使用
|
||||
|
||||
```typescript
|
||||
// 在游戏系统中使用
|
||||
import { IAudioService } from '@mygame/core';
|
||||
|
||||
class CombatSystem extends EntitySystem {
|
||||
private audio: IAudioService;
|
||||
|
||||
initialize(): void {
|
||||
// 获取音频服务,不需要知道具体实现
|
||||
this.audio = this.scene.services.resolve<IAudioService>(IAudioService);
|
||||
}
|
||||
|
||||
onEntityDeath(entity: Entity): void {
|
||||
this.audio.playSound('death');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Symbol vs Symbol.for
|
||||
|
||||
```typescript
|
||||
// Symbol() - 每次创建唯一的 Symbol
|
||||
const sym1 = Symbol('test');
|
||||
const sym2 = Symbol('test');
|
||||
console.log(sym1 === sym2); // false - 不同的 Symbol
|
||||
|
||||
// Symbol.for() - 在全局注册表中共享
|
||||
const sym3 = Symbol.for('test');
|
||||
const sym4 = Symbol.for('test');
|
||||
console.log(sym3 === sym4); // true - 同一个 Symbol
|
||||
|
||||
// 跨包场景
|
||||
// package-a/index.ts
|
||||
export const IMyService = Symbol.for('IMyService');
|
||||
|
||||
// package-b/index.ts (不同的包)
|
||||
const IMyService = Symbol.for('IMyService');
|
||||
// 与 package-a 中的是同一个 Symbol!
|
||||
```
|
||||
|
||||
### 循环依赖检测
|
||||
|
||||
服务容器会自动检测循环依赖:
|
||||
|
||||
```typescript
|
||||
// A 依赖 B,B 依赖 A
|
||||
@Injectable()
|
||||
class ServiceA implements IService {
|
||||
constructor(@Inject(ServiceB) b: ServiceB) {}
|
||||
dispose(): void {}
|
||||
}
|
||||
|
||||
@Injectable()
|
||||
class ServiceB implements IService {
|
||||
constructor(@Inject(ServiceA) a: ServiceA) {}
|
||||
dispose(): void {}
|
||||
}
|
||||
|
||||
// 解析时会抛出错误: Circular dependency detected: ServiceA -> ServiceB -> ServiceA
|
||||
```
|
||||
|
||||
### 获取所有服务
|
||||
|
||||
```typescript
|
||||
// 获取所有已注册的服务类型
|
||||
const types = Core.services.getRegisteredServices();
|
||||
|
||||
// 获取所有已实例化的服务实例
|
||||
const instances = Core.services.getAll();
|
||||
```
|
||||
|
||||
### 服务清理
|
||||
|
||||
```typescript
|
||||
// 注销单个服务
|
||||
Core.services.unregister(MyService);
|
||||
|
||||
// 清空所有服务(会调用每个服务的dispose方法)
|
||||
Core.services.clear();
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 服务命名
|
||||
|
||||
服务类名应该以 `Service` 或 `Manager` 结尾,清晰表达其职责:
|
||||
|
||||
```typescript
|
||||
class PlayerService implements IService {}
|
||||
class AudioManager implements IService {}
|
||||
class NetworkService implements IService {}
|
||||
```
|
||||
|
||||
### 资源清理
|
||||
|
||||
始终在 `dispose()` 方法中清理资源:
|
||||
|
||||
```typescript
|
||||
class ResourceService implements IService {
|
||||
private resources: Map<string, Resource> = new Map();
|
||||
|
||||
dispose(): void {
|
||||
// 释放所有资源
|
||||
for (const resource of this.resources.values()) {
|
||||
resource.release();
|
||||
}
|
||||
this.resources.clear();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 避免过度使用
|
||||
|
||||
不要把所有类都注册为服务,服务应该是:
|
||||
|
||||
- 全局单例或需要共享状态
|
||||
- 需要在多处使用
|
||||
- 生命周期需要管理
|
||||
- 需要依赖注入
|
||||
|
||||
对于简单的工具类或数据类,直接创建实例即可。
|
||||
|
||||
### 依赖方向
|
||||
|
||||
保持清晰的依赖方向,避免循环依赖:
|
||||
|
||||
```
|
||||
高层服务 -> 中层服务 -> 底层服务
|
||||
GameLogic -> DataService -> ConfigService
|
||||
```
|
||||
|
||||
## 常见问题
|
||||
|
||||
### 服务未注册错误
|
||||
|
||||
**问题**: `Error: Service MyService is not registered`
|
||||
|
||||
**解决**:
|
||||
```typescript
|
||||
// 确保服务已注册
|
||||
Core.services.registerSingleton(MyService);
|
||||
|
||||
// 或者使用tryResolve
|
||||
const service = Core.services.tryResolve(MyService);
|
||||
if (!service) {
|
||||
console.log('Service not found');
|
||||
}
|
||||
```
|
||||
|
||||
### 循环依赖错误
|
||||
|
||||
**问题**: `Circular dependency detected`
|
||||
|
||||
**解决**: 重新设计服务依赖关系,引入中间服务或使用事件系统解耦。
|
||||
|
||||
### 何时使用单例 vs 瞬时
|
||||
|
||||
- **单例**: 管理器类、配置、缓存、状态管理
|
||||
- **瞬时**: 命令对象、请求处理器、临时任务

# 系统架构
|
||||
|
||||
在 ECS 架构中,系统(System)是处理业务逻辑的地方。系统负责对拥有特定组件组合的实体执行操作,是 ECS 架构的逻辑处理单元。
|
||||
|
||||
## 基本概念
|
||||
|
||||
系统是继承自 `EntitySystem` 抽象基类的具体类,用于:
|
||||
- 定义实体的处理逻辑(如移动、碰撞检测、渲染等)
|
||||
- 根据组件组合筛选需要处理的实体
|
||||
- 提供生命周期管理和性能监控
|
||||
- 管理实体的添加、移除事件
|
||||
|
||||
## 系统类型
|
||||
|
||||
框架提供了几种不同类型的系统基类:
|
||||
|
||||
### EntitySystem - 基础系统
|
||||
|
||||
最基础的系统类,所有其他系统都继承自它:
|
||||
|
||||
```typescript
|
||||
import { EntitySystem, ECSSystem, Matcher } from '@esengine/ecs-framework';
|
||||
|
||||
@ECSSystem('Movement')
|
||||
class MovementSystem extends EntitySystem {
|
||||
constructor() {
|
||||
// 使用 Matcher 定义需要处理的实体条件
|
||||
super(Matcher.all(Position, Velocity));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const position = entity.getComponent(Position);
|
||||
const velocity = entity.getComponent(Velocity);
|
||||
|
||||
if (position && velocity) {
|
||||
position.x += velocity.dx * Time.deltaTime;
|
||||
position.y += velocity.dy * Time.deltaTime;
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### ProcessingSystem - 处理系统
|
||||
|
||||
适用于不需要逐个处理实体的系统:
|
||||
|
||||
```typescript
|
||||
@ECSSystem('Physics')
|
||||
class PhysicsSystem extends ProcessingSystem {
|
||||
constructor() {
|
||||
super(); // 不需要指定 Matcher
|
||||
}
|
||||
|
||||
public processSystem(): void {
|
||||
// 执行物理世界步进
|
||||
this.physicsWorld.step(Time.deltaTime);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### PassiveSystem - 被动系统
|
||||
|
||||
被动系统不进行主动处理,主要用于监听实体的添加和移除事件:
|
||||
|
||||
```typescript
|
||||
@ECSSystem('EntityTracker')
|
||||
class EntityTrackerSystem extends PassiveSystem {
|
||||
constructor() {
|
||||
super(Matcher.all(Health));
|
||||
}
|
||||
|
||||
protected onAdded(entity: Entity): void {
|
||||
console.log(`生命值实体被添加: ${entity.name}`);
|
||||
}
|
||||
|
||||
protected onRemoved(entity: Entity): void {
|
||||
console.log(`生命值实体被移除: ${entity.name}`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### IntervalSystem - 间隔系统
|
||||
|
||||
按固定时间间隔执行的系统:
|
||||
|
||||
```typescript
|
||||
@ECSSystem('AutoSave')
|
||||
class AutoSaveSystem extends IntervalSystem {
|
||||
constructor() {
|
||||
// 每 5 秒执行一次
|
||||
super(5.0, Matcher.all(SaveData));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
console.log('执行自动保存...');
|
||||
// 保存游戏数据
|
||||
this.saveGameData(entities);
|
||||
}
|
||||
|
||||
private saveGameData(entities: readonly Entity[]): void {
|
||||
// 保存逻辑
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### WorkerEntitySystem - 多线程系统
|
||||
|
||||
基于Web Worker的多线程处理系统,适用于计算密集型任务,能够充分利用多核CPU性能。
|
||||
|
||||
Worker系统提供了真正的并行计算能力,支持SharedArrayBuffer优化,并具有自动降级支持。特别适合物理模拟、粒子系统、AI计算等场景。
|
||||
|
||||
**详细内容请参考:[Worker系统](/guide/worker-system)**
|
||||
|
||||
## 实体匹配器 (Matcher)
|
||||
|
||||
Matcher 用于定义系统需要处理哪些实体。它提供了灵活的条件组合:
|
||||
|
||||
### 基本匹配条件
|
||||
|
||||
```typescript
|
||||
// 必须同时拥有 Position 和 Velocity 组件
|
||||
const matcher1 = Matcher.all(Position, Velocity);
|
||||
|
||||
// 至少拥有 Health 或 Shield 组件之一
|
||||
const matcher2 = Matcher.any(Health, Shield);
|
||||
|
||||
// 不能拥有 Dead 组件
|
||||
const matcher3 = Matcher.none(Dead);
|
||||
```
|
||||
|
||||
### 复合匹配条件
|
||||
|
||||
```typescript
|
||||
// 复杂的组合条件
|
||||
const complexMatcher = Matcher.all(Position, Velocity)
|
||||
.any(Player, Enemy)
|
||||
.none(Dead, Disabled);
|
||||
|
||||
@ECSSystem('Combat')
|
||||
class CombatSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(complexMatcher);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 特殊匹配条件
|
||||
|
||||
```typescript
|
||||
// 按标签匹配
|
||||
const tagMatcher = Matcher.byTag(1); // 匹配标签为 1 的实体
|
||||
|
||||
// 按名称匹配
|
||||
const nameMatcher = Matcher.byName("Player"); // 匹配名称为 "Player" 的实体
|
||||
|
||||
// 单组件匹配
|
||||
const componentMatcher = Matcher.byComponent(Health); // 匹配拥有 Health 组件的实体
|
||||
|
||||
// 不匹配任何实体
|
||||
const nothingMatcher = Matcher.nothing(); // 用于只需要生命周期回调的系统
|
||||
```
|
||||
|
||||
### 空匹配器 vs Nothing 匹配器
|
||||
|
||||
```typescript
|
||||
// empty() - 空条件,匹配所有实体
|
||||
const emptyMatcher = Matcher.empty();
|
||||
|
||||
// nothing() - 不匹配任何实体,用于只需要生命周期方法的系统
|
||||
const nothingMatcher = Matcher.nothing();
|
||||
|
||||
// 使用场景:只需要 onBegin/onEnd 生命周期的系统
|
||||
@ECSSystem('FrameTimer')
|
||||
class FrameTimerSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.nothing()); // 不处理任何实体
|
||||
}
|
||||
|
||||
protected onBegin(): void {
|
||||
// 每帧开始时执行,例如:记录帧开始时间
|
||||
console.log('帧开始');
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 永远不会被调用,因为没有匹配的实体
|
||||
}
|
||||
|
||||
protected onEnd(): void {
|
||||
// 每帧结束时执行
|
||||
console.log('帧结束');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
> 💡 **提示**:更多关于 Matcher 和实体查询的详细用法,请参考 [实体查询系统](/guide/entity-query) 文档。
|
||||
|
||||
## 系统生命周期
|
||||
|
||||
系统提供了完整的生命周期回调:
|
||||
|
||||
```typescript
|
||||
@ECSSystem('Example')
|
||||
class ExampleSystem extends EntitySystem {
|
||||
protected onInitialize(): void {
|
||||
console.log('系统初始化');
|
||||
// 系统被添加到场景时调用,用于初始化资源
|
||||
}
|
||||
|
||||
protected onBegin(): void {
|
||||
// 每帧处理开始前调用
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 主要的处理逻辑
|
||||
for (const entity of entities) {
|
||||
// 处理每个实体
|
||||
}
|
||||
}
|
||||
|
||||
protected lateProcess(entities: readonly Entity[]): void {
|
||||
// 主处理之后的后期处理
|
||||
}
|
||||
|
||||
protected onEnd(): void {
|
||||
// 每帧处理结束后调用
|
||||
}
|
||||
|
||||
protected onDestroy(): void {
|
||||
console.log('系统销毁');
|
||||
// 系统从场景移除时调用,用于清理资源
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 实体事件监听
|
||||
|
||||
系统可以监听实体的添加和移除事件:
|
||||
|
||||
```typescript
|
||||
@ECSSystem('EnemyManager')
|
||||
class EnemyManagerSystem extends EntitySystem {
|
||||
private enemyCount = 0;
|
||||
|
||||
constructor() {
|
||||
super(Matcher.all(Enemy, Health));
|
||||
}
|
||||
|
||||
protected onAdded(entity: Entity): void {
|
||||
this.enemyCount++;
|
||||
console.log(`敌人加入战斗,当前敌人数量: ${this.enemyCount}`);
|
||||
|
||||
// 可以在这里为新敌人设置初始状态
|
||||
const health = entity.getComponent(Health);
|
||||
if (health) {
|
||||
health.current = health.max;
|
||||
}
|
||||
}
|
||||
|
||||
protected onRemoved(entity: Entity): void {
|
||||
this.enemyCount--;
|
||||
console.log(`敌人被移除,剩余敌人数量: ${this.enemyCount}`);
|
||||
|
||||
// 检查是否所有敌人都被消灭
|
||||
if (this.enemyCount === 0) {
|
||||
this.scene?.eventSystem.emitSync('all_enemies_defeated');
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 系统属性和方法
|
||||
|
||||
### 重要属性
|
||||
|
||||
```typescript
|
||||
@ECSSystem('Example')
|
||||
class ExampleSystem extends EntitySystem {
|
||||
showSystemInfo(): void {
|
||||
console.log(`系统名称: ${this.systemName}`); // 系统名称
|
||||
console.log(`更新顺序: ${this.updateOrder}`); // 更新时序
|
||||
console.log(`是否启用: ${this.enabled}`); // 启用状态
|
||||
console.log(`实体数量: ${this.entities.length}`); // 匹配的实体数量
|
||||
console.log(`所属场景: ${this.scene?.name}`); // 所属场景
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 实体访问
|
||||
|
||||
```typescript
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 方式1:使用参数中的实体列表
|
||||
for (const entity of entities) {
|
||||
// 处理实体
|
||||
}
|
||||
|
||||
// 方式2:使用 this.entities 属性(与参数相同)
|
||||
for (const entity of this.entities) {
|
||||
// 处理实体
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 控制系统执行
|
||||
|
||||
```typescript
|
||||
@ECSSystem('Conditional')
|
||||
class ConditionalSystem extends EntitySystem {
|
||||
private shouldProcess = true;
|
||||
|
||||
protected onCheckProcessing(): boolean {
|
||||
// 返回 false 时跳过本次处理
|
||||
return this.shouldProcess && this.entities.length > 0;
|
||||
}
|
||||
|
||||
public pause(): void {
|
||||
this.shouldProcess = false;
|
||||
}
|
||||
|
||||
public resume(): void {
|
||||
this.shouldProcess = true;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 事件系统集成
|
||||
|
||||
系统可以方便地监听和发送事件:
|
||||
|
||||
```typescript
|
||||
@ECSSystem('GameLogic')
|
||||
class GameLogicSystem extends EntitySystem {
|
||||
protected onInitialize(): void {
|
||||
// 添加事件监听器(系统销毁时自动清理)
|
||||
this.addEventListener('player_died', this.onPlayerDied.bind(this));
|
||||
this.addEventListener('level_complete', this.onLevelComplete.bind(this));
|
||||
}
|
||||
|
||||
private onPlayerDied(data: any): void {
|
||||
console.log('玩家死亡,重新开始游戏');
|
||||
// 处理玩家死亡逻辑
|
||||
}
|
||||
|
||||
private onLevelComplete(data: any): void {
|
||||
console.log('关卡完成,加载下一关');
|
||||
// 处理关卡完成逻辑
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 在处理过程中发送事件
|
||||
for (const entity of entities) {
|
||||
const health = entity.getComponent(Health);
|
||||
if (health && health.current <= 0) {
|
||||
this.scene?.eventSystem.emitSync('entity_died', { entity });
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 性能监控
|
||||
|
||||
系统内置了性能监控功能:
|
||||
|
||||
```typescript
|
||||
@ECSSystem('Performance')
|
||||
class PerformanceSystem extends EntitySystem {
|
||||
protected onEnd(): void {
|
||||
// 获取性能数据
|
||||
const perfData = this.getPerformanceData();
|
||||
if (perfData) {
|
||||
console.log(`执行时间: ${perfData.executionTime.toFixed(2)}ms`);
|
||||
}
|
||||
|
||||
// 获取性能统计
|
||||
const stats = this.getPerformanceStats();
|
||||
if (stats) {
|
||||
console.log(`平均执行时间: ${stats.averageTime.toFixed(2)}ms`);
|
||||
}
|
||||
}
|
||||
|
||||
public resetPerformance(): void {
|
||||
this.resetPerformanceData();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 系统管理
|
||||
|
||||
### 添加系统到场景
|
||||
|
||||
框架提供了两种方式添加系统:传入实例或传入类型(自动依赖注入)。
|
||||
|
||||
```typescript
|
||||
// 在场景子类中添加系统
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 方式1:传入实例
|
||||
this.addSystem(new MovementSystem());
|
||||
this.addSystem(new RenderSystem());
|
||||
|
||||
// 方式2:传入类型(自动依赖注入)
|
||||
this.addEntityProcessor(PhysicsSystem);
|
||||
|
||||
// 设置系统更新顺序
|
||||
const movementSystem = this.getSystem(MovementSystem);
|
||||
if (movementSystem) {
|
||||
movementSystem.updateOrder = 1;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 系统依赖注入
|
||||
|
||||
系统实现了 `IService` 接口,支持通过依赖注入获取其他服务或系统:
|
||||
|
||||
```typescript
|
||||
import { ECSSystem, Injectable, Inject } from '@esengine/ecs-framework';
|
||||
|
||||
@Injectable()
|
||||
@ECSSystem('Physics')
|
||||
class PhysicsSystem extends EntitySystem {
|
||||
constructor(
|
||||
@Inject(CollisionService) private collision: CollisionService
|
||||
) {
|
||||
super(Matcher.all(Transform, RigidBody));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 使用注入的服务
|
||||
this.collision.detectCollisions(entities);
|
||||
}
|
||||
|
||||
// 实现 IService 接口的 dispose 方法
|
||||
public dispose(): void {
|
||||
// 清理资源
|
||||
}
|
||||
}
|
||||
|
||||
// 使用时传入类型即可,框架会自动注入依赖
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 自动依赖注入
|
||||
this.addEntityProcessor(PhysicsSystem);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
注意事项:
|
||||
- 使用 `@Injectable()` 装饰器标记需要依赖注入的系统
|
||||
- 在构造函数参数中使用 `@Inject()` 装饰器声明依赖
|
||||
- 系统必须实现 `dispose()` 方法(IService 接口要求)
|
||||
- 使用 `addEntityProcessor(类型)` 而不是 `addSystem(new 类型())` 来启用依赖注入
|
||||
|
||||
### 系统更新顺序
|
||||
|
||||
```typescript
|
||||
@ECSSystem('Input')
|
||||
class InputSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(InputComponent));
|
||||
this.updateOrder = -100; // 输入系统优先执行
|
||||
}
|
||||
}
|
||||
|
||||
@ECSSystem('Physics')
|
||||
class PhysicsSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(RigidBody));
|
||||
this.updateOrder = 0; // 默认顺序
|
||||
}
|
||||
}
|
||||
|
||||
@ECSSystem('Render')
|
||||
class RenderSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(Sprite, Transform));
|
||||
this.updateOrder = 100; // 渲染系统最后执行
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 复杂系统示例
|
||||
|
||||
### 碰撞检测系统
|
||||
|
||||
```typescript
|
||||
@ECSSystem('Collision')
|
||||
class CollisionSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(Transform, Collider));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 简单的 n² 碰撞检测
|
||||
for (let i = 0; i < entities.length; i++) {
|
||||
for (let j = i + 1; j < entities.length; j++) {
|
||||
this.checkCollision(entities[i], entities[j]);
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
private checkCollision(entityA: Entity, entityB: Entity): void {
|
||||
const transformA = entityA.getComponent(Transform);
|
||||
const transformB = entityB.getComponent(Transform);
|
||||
const colliderA = entityA.getComponent(Collider);
|
||||
const colliderB = entityB.getComponent(Collider);
|
||||
|
||||
if (this.isColliding(transformA, colliderA, transformB, colliderB)) {
|
||||
// 发送碰撞事件
|
||||
this.scene?.eventSystem.emitSync('collision', {
|
||||
entityA,
|
||||
entityB
|
||||
});
|
||||
}
|
||||
}
|
||||
|
||||
private isColliding(transformA: Transform, colliderA: Collider,
|
||||
transformB: Transform, colliderB: Collider): boolean {
|
||||
// 碰撞检测逻辑
|
||||
return false; // 简化示例
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 状态机系统
|
||||
|
||||
```typescript
|
||||
@ECSSystem('StateMachine')
|
||||
class StateMachineSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(StateMachine));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const stateMachine = entity.getComponent(StateMachine);
|
||||
if (stateMachine) {
|
||||
stateMachine.updateTimer(Time.deltaTime);
|
||||
this.updateState(entity, stateMachine);
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
private updateState(entity: Entity, stateMachine: StateMachine): void {
|
||||
switch (stateMachine.currentState) {
|
||||
case EntityState.Idle:
|
||||
this.handleIdleState(entity, stateMachine);
|
||||
break;
|
||||
case EntityState.Moving:
|
||||
this.handleMovingState(entity, stateMachine);
|
||||
break;
|
||||
case EntityState.Attacking:
|
||||
this.handleAttackingState(entity, stateMachine);
|
||||
break;
|
||||
}
|
||||
}
|
||||
|
||||
private handleIdleState(entity: Entity, stateMachine: StateMachine): void {
|
||||
// 空闲状态逻辑
|
||||
}
|
||||
|
||||
private handleMovingState(entity: Entity, stateMachine: StateMachine): void {
|
||||
// 移动状态逻辑
|
||||
}
|
||||
|
||||
private handleAttackingState(entity: Entity, stateMachine: StateMachine): void {
|
||||
// 攻击状态逻辑
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 系统单一职责
|
||||
|
||||
```typescript
|
||||
// ✅ 好的系统设计 - 职责单一
|
||||
@ECSSystem('Movement')
|
||||
class MovementSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(Position, Velocity));
|
||||
}
|
||||
}
|
||||
|
||||
@ECSSystem('Rendering')
|
||||
class RenderingSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(Sprite, Transform));
|
||||
}
|
||||
}
|
||||
|
||||
// ❌ 避免的系统设计 - 职责过多
|
||||
@ECSSystem('GameSystem')
|
||||
class GameSystem extends EntitySystem {
|
||||
// 一个系统处理移动、渲染、音效等多种逻辑
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 使用 @ECSSystem 装饰器
|
||||
|
||||
`@ECSSystem` 是系统类必须使用的装饰器,它为系统提供类型标识和元数据管理。
|
||||
|
||||
#### 为什么必须使用
|
||||
|
||||
| 功能 | 说明 |
|
||||
|------|------|
|
||||
| **类型识别** | 提供稳定的系统名称,代码混淆后仍能正确识别 |
|
||||
| **调试支持** | 在性能监控、日志和调试工具中显示可读的系统名称 |
|
||||
| **系统管理** | 通过名称查找和管理系统 |
|
||||
| **序列化支持** | 场景序列化时可以记录系统配置 |
|
||||
|
||||
#### 基本语法
|
||||
|
||||
```typescript
|
||||
@ECSSystem(systemName: string)
|
||||
```
|
||||
|
||||
- `systemName`: 系统的名称,建议使用描述性的名称
|
||||
|
||||
#### 使用示例
|
||||
|
||||
```typescript
|
||||
// ✅ 正确的用法
|
||||
@ECSSystem('Physics')
|
||||
class PhysicsSystem extends EntitySystem {
|
||||
// 系统实现
|
||||
}
|
||||
|
||||
// ✅ 推荐:使用描述性的名称
|
||||
@ECSSystem('PlayerMovement')
|
||||
class PlayerMovementSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(Player, Position, Velocity));
|
||||
}
|
||||
}
|
||||
|
||||
// ❌ 错误的用法 - 没有装饰器
|
||||
class BadSystem extends EntitySystem {
|
||||
// 这样定义的系统可能在生产环境出现问题:
|
||||
// 1. 代码压缩后类名变化,无法正确识别
|
||||
// 2. 性能监控和调试工具显示不正确的名称
|
||||
}
|
||||
```
|
||||
|
||||
#### 系统名称的作用
|
||||
|
||||
```typescript
|
||||
@ECSSystem('Combat')
|
||||
class CombatSystem extends EntitySystem {
|
||||
protected onInitialize(): void {
|
||||
// 使用 systemName 属性访问系统名称
|
||||
console.log(`系统 ${this.systemName} 已初始化`); // 输出: 系统 Combat 已初始化
|
||||
}
|
||||
}
|
||||
|
||||
// 通过名称查找系统
|
||||
const combat = scene.getSystemByName('Combat');
|
||||
|
||||
// 性能监控中会显示系统名称
|
||||
const perfData = combatSystem.getPerformanceData();
|
||||
console.log(`${combatSystem.systemName} 执行时间: ${perfData?.executionTime}ms`);
|
||||
```
|
||||
|
||||
### 3. 合理的更新顺序
|
||||
|
||||
```typescript
|
||||
// 按逻辑顺序设置系统的更新时序
|
||||
@ECSSystem('Input')
|
||||
class InputSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super();
|
||||
this.updateOrder = -100; // 最先处理输入
|
||||
}
|
||||
}
|
||||
|
||||
@ECSSystem('Logic')
|
||||
class GameLogicSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super();
|
||||
this.updateOrder = 0; // 处理游戏逻辑
|
||||
}
|
||||
}
|
||||
|
||||
@ECSSystem('Render')
|
||||
class RenderSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super();
|
||||
this.updateOrder = 100; // 最后进行渲染
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 避免在系统间直接引用
|
||||
|
||||
```typescript
|
||||
// ❌ 避免:系统间直接引用
|
||||
@ECSSystem('Bad')
|
||||
class BadSystem extends EntitySystem {
|
||||
private otherSystem: SomeOtherSystem; // 避免直接引用其他系统
|
||||
}
|
||||
|
||||
// ✅ 推荐:通过事件系统通信
|
||||
@ECSSystem('Good')
|
||||
class GoodSystem extends EntitySystem {
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 通过事件系统与其他系统通信
|
||||
this.scene?.eventSystem.emitSync('data_updated', { entities });
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 5. 及时清理资源
|
||||
|
||||
```typescript
|
||||
@ECSSystem('Resource')
|
||||
class ResourceSystem extends EntitySystem {
|
||||
private resources: Map<string, any> = new Map();
|
||||
|
||||
protected onDestroy(): void {
|
||||
// 清理资源
|
||||
for (const [key, resource] of this.resources) {
|
||||
if (resource.dispose) {
|
||||
resource.dispose();
|
||||
}
|
||||
}
|
||||
this.resources.clear();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
系统是 ECS 架构的逻辑处理核心,正确设计和使用系统能让你的游戏代码更加模块化、高效和易于维护。

# 时间和定时器系统
|
||||
|
||||
ECS 框架提供了完整的时间管理和定时器系统,包括时间缩放、帧时间计算和灵活的定时器调度功能。
|
||||
|
||||
## Time 类
|
||||
|
||||
Time 类是框架的时间管理核心,提供了游戏时间相关的所有功能。
|
||||
|
||||
### 基本时间属性
|
||||
|
||||
```typescript
|
||||
import { Time } from '@esengine/ecs-framework';
|
||||
|
||||
class GameSystem extends EntitySystem {
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 获取帧时间(秒)
|
||||
const deltaTime = Time.deltaTime;
|
||||
|
||||
// 获取未缩放的帧时间
|
||||
const unscaledDelta = Time.unscaledDeltaTime;
|
||||
|
||||
// 获取游戏总时间
|
||||
const totalTime = Time.totalTime;
|
||||
|
||||
// 获取当前帧数
|
||||
const frameCount = Time.frameCount;
|
||||
|
||||
console.log(`第 ${frameCount} 帧,帧时间: ${deltaTime}s,总时间: ${totalTime}s`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 时间缩放
|
||||
|
||||
Time 类支持时间缩放功能,可以实现慢动作、快进等效果:
|
||||
|
||||
```typescript
|
||||
class TimeControlSystem extends EntitySystem {
|
||||
public enableSlowMotion(): void {
|
||||
// 设置为慢动作(50%速度)
|
||||
Time.timeScale = 0.5;
|
||||
console.log('慢动作模式启用');
|
||||
}
|
||||
|
||||
public enableFastForward(): void {
|
||||
// 设置为快进(200%速度)
|
||||
Time.timeScale = 2.0;
|
||||
console.log('快进模式启用');
|
||||
}
|
||||
|
||||
public pauseGame(): void {
|
||||
// 暂停游戏(时间静止)
|
||||
Time.timeScale = 0;
|
||||
console.log('游戏暂停');
|
||||
}
|
||||
|
||||
public resumeNormalSpeed(): void {
|
||||
// 恢复正常速度
|
||||
Time.timeScale = 1.0;
|
||||
console.log('恢复正常速度');
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// deltaTime 会受到 timeScale 影响
|
||||
const scaledDelta = Time.deltaTime; // 受时间缩放影响
|
||||
const realDelta = Time.unscaledDeltaTime; // 不受时间缩放影响
|
||||
|
||||
for (const entity of entities) {
|
||||
const movement = entity.getComponent(Movement);
|
||||
if (movement) {
|
||||
// 使用缩放时间进行游戏逻辑更新
|
||||
movement.update(scaledDelta);
|
||||
}
|
||||
|
||||
const ui = entity.getComponent(UIComponent);
|
||||
if (ui) {
|
||||
// UI 动画使用真实时间,不受游戏时间缩放影响
|
||||
ui.update(realDelta);
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 时间检查工具
|
||||
|
||||
```typescript
|
||||
class CooldownSystem extends EntitySystem {
|
||||
private lastAttackTime = 0;
|
||||
private lastSpawnTime = 0;
|
||||
|
||||
constructor() {
|
||||
super(Matcher.all(Weapon));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 检查攻击冷却
|
||||
if (Time.checkEvery(1.5, this.lastAttackTime)) {
|
||||
this.performAttack();
|
||||
this.lastAttackTime = Time.totalTime;
|
||||
}
|
||||
|
||||
// 检查生成间隔
|
||||
if (Time.checkEvery(3.0, this.lastSpawnTime)) {
|
||||
this.spawnEnemy();
|
||||
this.lastSpawnTime = Time.totalTime;
|
||||
}
|
||||
}
|
||||
|
||||
private performAttack(): void {
|
||||
console.log('执行攻击!');
|
||||
}
|
||||
|
||||
private spawnEnemy(): void {
|
||||
console.log('生成敌人!');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Core.schedule 定时器系统
|
||||
|
||||
Core 提供了强大的定时器调度功能,可以创建一次性或重复执行的定时器。
|
||||
|
||||
### 基本定时器使用
|
||||
|
||||
```typescript
|
||||
import { Core } from '@esengine/ecs-framework';
|
||||
|
||||
class GameScene extends Scene {
|
||||
protected initialize(): void {
|
||||
// 创建一次性定时器
|
||||
this.createOneTimeTimers();
|
||||
|
||||
// 创建重复定时器
|
||||
this.createRepeatingTimers();
|
||||
|
||||
// 创建带上下文的定时器
|
||||
this.createContextTimers();
|
||||
}
|
||||
|
||||
private createOneTimeTimers(): void {
|
||||
// 2秒后执行一次
|
||||
Core.schedule(2.0, false, null, (timer) => {
|
||||
console.log('2秒延迟执行');
|
||||
});
|
||||
|
||||
// 5秒后显示提示
|
||||
Core.schedule(5.0, false, this, (timer) => {
|
||||
const scene = timer.getContext<GameScene>();
|
||||
scene.showTip('游戏提示:5秒已过!');
|
||||
});
|
||||
}
|
||||
|
||||
private createRepeatingTimers(): void {
|
||||
// 每秒重复执行
|
||||
const heartbeatTimer = Core.schedule(1.0, true, null, (timer) => {
|
||||
console.log(`游戏心跳 - 总时间: ${Time.totalTime.toFixed(1)}s`);
|
||||
});
|
||||
|
||||
// 可以保存定时器引用用于后续控制
|
||||
this.saveTimerReference(heartbeatTimer);
|
||||
}
|
||||
|
||||
private createContextTimers(): void {
|
||||
const gameData = { score: 0, level: 1 };
|
||||
|
||||
// 每2秒增加分数
|
||||
Core.schedule(2.0, true, gameData, (timer) => {
|
||||
const data = timer.getContext<typeof gameData>();
|
||||
data.score += 10;
|
||||
console.log(`分数增加!当前分数: ${data.score}`);
|
||||
});
|
||||
}
|
||||
|
||||
private saveTimerReference(timer: any): void {
|
||||
// 可以稍后停止定时器
|
||||
setTimeout(() => {
|
||||
timer.stop();
|
||||
console.log('定时器已停止');
|
||||
}, 10000); // 10秒后停止
|
||||
}
|
||||
|
||||
private showTip(message: string): void {
|
||||
console.log('提示:', message);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 定时器控制
|
||||
|
||||
```typescript
|
||||
class TimerControlExample {
|
||||
private attackTimer: any;
|
||||
private spawnerTimer: any;
|
||||
|
||||
public startCombat(): void {
|
||||
// 启动攻击定时器
|
||||
this.attackTimer = Core.schedule(0.5, true, this, (timer) => {
|
||||
const self = timer.getContext<TimerControlExample>();
|
||||
self.performAttack();
|
||||
});
|
||||
|
||||
// 启动敌人生成定时器
|
||||
this.spawnerTimer = Core.schedule(3.0, true, null, (timer) => {
|
||||
this.spawnEnemy();
|
||||
});
|
||||
}
|
||||
|
||||
public stopCombat(): void {
|
||||
// 停止所有战斗相关定时器
|
||||
if (this.attackTimer) {
|
||||
this.attackTimer.stop();
|
||||
console.log('攻击定时器已停止');
|
||||
}
|
||||
|
||||
if (this.spawnerTimer) {
|
||||
this.spawnerTimer.stop();
|
||||
console.log('生成定时器已停止');
|
||||
}
|
||||
}
|
||||
|
||||
public resetAttackTimer(): void {
|
||||
// 重置攻击定时器
|
||||
if (this.attackTimer) {
|
||||
this.attackTimer.reset();
|
||||
console.log('攻击定时器已重置');
|
||||
}
|
||||
}
|
||||
|
||||
private performAttack(): void {
|
||||
console.log('执行攻击');
|
||||
}
|
||||
|
||||
private spawnEnemy(): void {
|
||||
console.log('生成敌人');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 复杂定时器场景
|
||||
|
||||
```typescript
|
||||
class AdvancedTimerUsage {
|
||||
private powerUpDuration = 0;
|
||||
private powerUpActive = false;
|
||||
|
||||
public activatePowerUp(): void {
|
||||
if (this.powerUpActive) {
|
||||
console.log('能力提升已激活');
|
||||
return;
|
||||
}
|
||||
|
||||
this.powerUpActive = true;
|
||||
this.powerUpDuration = 10; // 10秒持续时间
|
||||
|
||||
console.log('能力提升激活!');
|
||||
|
||||
// 每秒更新剩余时间
|
||||
const countdownTimer = Core.schedule(1.0, true, this, (timer) => {
|
||||
const self = timer.getContext<AdvancedTimerUsage>();
|
||||
self.powerUpDuration--;
|
||||
|
||||
console.log(`能力提升剩余时间: ${self.powerUpDuration}秒`);
|
||||
|
||||
if (self.powerUpDuration <= 0) {
|
||||
self.deactivatePowerUp();
|
||||
timer.stop(); // 停止倒计时
|
||||
}
|
||||
});
|
||||
|
||||
// 能力提升结束定时器(备用)
|
||||
Core.schedule(10.0, false, this, (timer) => {
|
||||
const self = timer.getContext<AdvancedTimerUsage>();
|
||||
if (self.powerUpActive) {
|
||||
self.deactivatePowerUp();
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
private deactivatePowerUp(): void {
|
||||
this.powerUpActive = false;
|
||||
this.powerUpDuration = 0;
|
||||
console.log('能力提升结束');
|
||||
}
|
||||
|
||||
// 创建波次攻击定时器
|
||||
public startWaveAttack(): void {
|
||||
let waveCount = 0;
|
||||
const maxWaves = 5;
|
||||
|
||||
const waveTimer = Core.schedule(2.0, true, { waveCount, maxWaves }, (timer) => {
|
||||
const context = timer.getContext<{ waveCount: number, maxWaves: number }>();
|
||||
context.waveCount++;
|
||||
|
||||
console.log(`第 ${context.waveCount} 波攻击!`);
|
||||
|
||||
if (context.waveCount >= context.maxWaves) {
|
||||
console.log('所有波次攻击完成');
|
||||
timer.stop();
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
// 创建条件定时器
|
||||
public startConditionalTimer(): void {
|
||||
Core.schedule(0.1, true, this, (timer) => {
|
||||
const self = timer.getContext<AdvancedTimerUsage>();
|
||||
|
||||
// 检查某个条件
|
||||
if (self.shouldStopTimer()) {
|
||||
console.log('条件满足,停止定时器');
|
||||
timer.stop();
|
||||
return;
|
||||
}
|
||||
|
||||
// 继续执行定时器逻辑
|
||||
self.performTimerAction();
|
||||
});
|
||||
}
|
||||
|
||||
private shouldStopTimer(): boolean {
|
||||
// 检查停止条件
|
||||
return Time.totalTime > 30; // 30秒后停止
|
||||
}
|
||||
|
||||
private performTimerAction(): void {
|
||||
console.log('执行定时器动作');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 实际应用示例
|
||||
|
||||
### 技能冷却系统
|
||||
|
||||
```typescript
|
||||
class SkillCooldownSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(SkillComponent));
|
||||
}
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const skill = entity.getComponent(SkillComponent);
|
||||
|
||||
// 更新技能冷却
|
||||
if (skill.isOnCooldown) {
|
||||
skill.cooldownRemaining -= Time.deltaTime;
|
||||
|
||||
if (skill.cooldownRemaining <= 0) {
|
||||
skill.cooldownRemaining = 0;
|
||||
skill.isOnCooldown = false;
|
||||
console.log(`技能 ${skill.name} 冷却完成`);
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
public useSkill(entity: Entity, skillName: string): boolean {
|
||||
const skill = entity.getComponent(SkillComponent);
|
||||
|
||||
if (skill.isOnCooldown) {
|
||||
console.log(`技能 ${skillName} 还在冷却中,剩余 ${skill.cooldownRemaining.toFixed(1)}秒`);
|
||||
return false;
|
||||
}
|
||||
|
||||
// 执行技能
|
||||
this.executeSkill(entity, skill);
|
||||
|
||||
// 开始冷却
|
||||
skill.isOnCooldown = true;
|
||||
skill.cooldownRemaining = skill.cooldownDuration;
|
||||
|
||||
return true;
|
||||
}
|
||||
|
||||
private executeSkill(entity: Entity, skill: SkillComponent): void {
|
||||
console.log(`执行技能: ${skill.name}`);
|
||||
// 技能效果逻辑
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 游戏状态定时器
|
||||
|
||||
```typescript
|
||||
class GameStateManager {
|
||||
private gamePhase = 'preparation';
|
||||
private phaseTimer: any;
|
||||
|
||||
public startGame(): void {
|
||||
this.startPreparationPhase();
|
||||
}
|
||||
|
||||
private startPreparationPhase(): void {
|
||||
this.gamePhase = 'preparation';
|
||||
console.log('准备阶段开始 - 10秒准备时间');
|
||||
|
||||
this.phaseTimer = Core.schedule(10.0, false, this, (timer) => {
|
||||
const self = timer.getContext<GameStateManager>();
|
||||
self.startCombatPhase();
|
||||
});
|
||||
}
|
||||
|
||||
private startCombatPhase(): void {
|
||||
this.gamePhase = 'combat';
|
||||
console.log('战斗阶段开始 - 60秒战斗时间');
|
||||
|
||||
this.phaseTimer = Core.schedule(60.0, false, this, (timer) => {
|
||||
const self = timer.getContext<GameStateManager>();
|
||||
self.startResultPhase();
|
||||
});
|
||||
|
||||
// 每10秒刷新一波敌人
|
||||
Core.schedule(10.0, true, null, (timer) => {
|
||||
if (this.gamePhase === 'combat') {
|
||||
this.spawnEnemyWave();
|
||||
} else {
|
||||
timer.stop(); // 战斗阶段结束时停止刷新
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
private startResultPhase(): void {
|
||||
this.gamePhase = 'result';
|
||||
console.log('结算阶段开始 - 5秒结算时间');
|
||||
|
||||
this.phaseTimer = Core.schedule(5.0, false, this, (timer) => {
|
||||
const self = timer.getContext<GameStateManager>();
|
||||
self.endGame();
|
||||
});
|
||||
}
|
||||
|
||||
private endGame(): void {
|
||||
console.log('游戏结束');
|
||||
this.gamePhase = 'ended';
|
||||
}
|
||||
|
||||
private spawnEnemyWave(): void {
|
||||
console.log('刷新敌人波次');
|
||||
}
|
||||
|
||||
public getCurrentPhase(): string {
|
||||
return this.gamePhase;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 合理使用时间类型
|
||||
|
||||
```typescript
|
||||
class MovementSystem extends EntitySystem {
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
for (const entity of entities) {
|
||||
const movement = entity.getComponent(Movement);
|
||||
|
||||
// ✅ 游戏逻辑使用缩放时间
|
||||
movement.position.x += movement.velocity.x * Time.deltaTime;
|
||||
|
||||
// ✅ UI动画使用真实时间(不受游戏暂停影响)
|
||||
const ui = entity.getComponent(UIAnimation);
|
||||
if (ui) {
|
||||
ui.update(Time.unscaledDeltaTime);
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 定时器管理
|
||||
|
||||
```typescript
|
||||
class TimerManager {
|
||||
private timers: any[] = [];
|
||||
|
||||
public createManagedTimer(duration: number, repeats: boolean, callback: () => void): any {
|
||||
const timer = Core.schedule(duration, repeats, null, callback);
|
||||
this.timers.push(timer);
|
||||
return timer;
|
||||
}
|
||||
|
||||
public stopAllTimers(): void {
|
||||
for (const timer of this.timers) {
|
||||
timer.stop();
|
||||
}
|
||||
this.timers = [];
|
||||
}
|
||||
|
||||
public cleanupCompletedTimers(): void {
|
||||
this.timers = this.timers.filter(timer => !timer.isDone);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 避免过多的定时器
|
||||
|
||||
```typescript
|
||||
// ❌ 避免:为每个实体创建定时器
|
||||
class BadExample extends EntitySystem {
|
||||
protected onAdded(entity: Entity): void {
|
||||
Core.schedule(1.0, true, entity, (timer) => {
|
||||
// 每个实体一个定时器,性能差
|
||||
});
|
||||
}
|
||||
}
|
||||
|
||||
// ✅ 推荐:在系统中统一管理时间
|
||||
class GoodExample extends EntitySystem {
|
||||
private lastUpdateTime = 0;
|
||||
|
||||
protected process(entities: readonly Entity[]): void {
|
||||
// 每秒执行一次逻辑
|
||||
if (Time.checkEvery(1.0, this.lastUpdateTime)) {
|
||||
this.processAllEntities(entities);
|
||||
this.lastUpdateTime = Time.totalTime;
|
||||
}
|
||||
}
|
||||
|
||||
private processAllEntities(entities: readonly Entity[]): void {
|
||||
// 批量处理所有实体
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 定时器上下文使用
|
||||
|
||||
```typescript
|
||||
interface TimerContext {
|
||||
entityId: number;
|
||||
duration: number;
|
||||
onComplete: () => void;
|
||||
}
|
||||
|
||||
class ContextualTimerExample {
|
||||
public createEntityTimer(entityId: number, duration: number, onComplete: () => void): void {
|
||||
const context: TimerContext = {
|
||||
entityId,
|
||||
duration,
|
||||
onComplete
|
||||
};
|
||||
|
||||
Core.schedule(duration, false, context, (timer) => {
|
||||
const ctx = timer.getContext<TimerContext>();
|
||||
console.log(`实体 ${ctx.entityId} 的定时器完成`);
|
||||
ctx.onComplete();
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
时间和定时器系统是游戏开发中的重要工具,正确使用这些功能能让你的游戏逻辑更加精确和可控。

# Worker系统
|
||||
|
||||
Worker系统(WorkerEntitySystem)是ECS框架中基于Web Worker的多线程处理系统,专为计算密集型任务设计,能够充分利用多核CPU性能,实现真正的并行计算。
|
||||
|
||||
## 核心特性
|
||||
|
||||
- **真正的并行计算**:利用Web Worker在后台线程执行计算密集型任务
|
||||
- **自动负载均衡**:根据CPU核心数自动分配工作负载
|
||||
- **SharedArrayBuffer优化**:零拷贝数据共享,提升大规模计算性能
|
||||
- **降级支持**:不支持Worker时自动回退到主线程处理
|
||||
- **类型安全**:完整的TypeScript支持和类型检查
|
||||
|
||||
## 基本用法
|
||||
|
||||
### 简单的物理系统示例
|
||||
|
||||
```typescript
|
||||
interface PhysicsData {
|
||||
id: number;
|
||||
x: number;
|
||||
y: number;
|
||||
vx: number;
|
||||
vy: number;
|
||||
mass: number;
|
||||
radius: number;
|
||||
}
|
||||
|
||||
@ECSSystem('Physics')
|
||||
class PhysicsWorkerSystem extends WorkerEntitySystem<PhysicsData> {
|
||||
constructor() {
|
||||
super(Matcher.all(Position, Velocity, Physics), {
|
||||
enableWorker: true, // 启用Worker并行处理
|
||||
workerCount: 8, // Worker数量,系统会自动限制在硬件支持范围内
|
||||
entitiesPerWorker: 100, // 每个Worker处理的实体数量
|
||||
useSharedArrayBuffer: true, // 启用SharedArrayBuffer优化
|
||||
entityDataSize: 7, // 每个实体数据大小
|
||||
maxEntities: 10000, // 最大实体数量
|
||||
systemConfig: { // 传递给Worker的配置
|
||||
gravity: 100,
|
||||
friction: 0.95
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
// 数据提取:将Entity转换为可序列化的数据
|
||||
protected extractEntityData(entity: Entity): PhysicsData {
|
||||
const position = entity.getComponent(Position);
|
||||
const velocity = entity.getComponent(Velocity);
|
||||
const physics = entity.getComponent(Physics);
|
||||
|
||||
return {
|
||||
id: entity.id,
|
||||
x: position.x,
|
||||
y: position.y,
|
||||
vx: velocity.x,
|
||||
vy: velocity.y,
|
||||
mass: physics.mass,
|
||||
radius: physics.radius
|
||||
};
|
||||
}
|
||||
|
||||
// Worker处理函数:纯函数,在Worker中执行
|
||||
protected workerProcess(
|
||||
entities: PhysicsData[],
|
||||
deltaTime: number,
|
||||
config: any
|
||||
): PhysicsData[] {
|
||||
return entities.map(entity => {
|
||||
// 应用重力
|
||||
entity.vy += config.gravity * deltaTime;
|
||||
|
||||
// 更新位置
|
||||
entity.x += entity.vx * deltaTime;
|
||||
entity.y += entity.vy * deltaTime;
|
||||
|
||||
// 应用摩擦力
|
||||
entity.vx *= config.friction;
|
||||
entity.vy *= config.friction;
|
||||
|
||||
return entity;
|
||||
});
|
||||
}
|
||||
|
||||
// 结果应用:将Worker处理结果应用回Entity
|
||||
protected applyResult(entity: Entity, result: PhysicsData): void {
|
||||
const position = entity.getComponent(Position);
|
||||
const velocity = entity.getComponent(Velocity);
|
||||
|
||||
position.x = result.x;
|
||||
position.y = result.y;
|
||||
velocity.x = result.vx;
|
||||
velocity.y = result.vy;
|
||||
}
|
||||
|
||||
// SharedArrayBuffer优化支持
|
||||
protected getDefaultEntityDataSize(): number {
|
||||
return 7; // id, x, y, vx, vy, mass, radius
|
||||
}
|
||||
|
||||
protected writeEntityToBuffer(entityData: PhysicsData, offset: number): void {
|
||||
if (!this.sharedFloatArray) return;
|
||||
|
||||
this.sharedFloatArray[offset + 0] = entityData.id;
|
||||
this.sharedFloatArray[offset + 1] = entityData.x;
|
||||
this.sharedFloatArray[offset + 2] = entityData.y;
|
||||
this.sharedFloatArray[offset + 3] = entityData.vx;
|
||||
this.sharedFloatArray[offset + 4] = entityData.vy;
|
||||
this.sharedFloatArray[offset + 5] = entityData.mass;
|
||||
this.sharedFloatArray[offset + 6] = entityData.radius;
|
||||
}
|
||||
|
||||
protected readEntityFromBuffer(offset: number): PhysicsData | null {
|
||||
if (!this.sharedFloatArray) return null;
|
||||
|
||||
return {
|
||||
id: this.sharedFloatArray[offset + 0],
|
||||
x: this.sharedFloatArray[offset + 1],
|
||||
y: this.sharedFloatArray[offset + 2],
|
||||
vx: this.sharedFloatArray[offset + 3],
|
||||
vy: this.sharedFloatArray[offset + 4],
|
||||
mass: this.sharedFloatArray[offset + 5],
|
||||
radius: this.sharedFloatArray[offset + 6]
|
||||
};
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 配置选项
|
||||
|
||||
Worker系统支持丰富的配置选项:
|
||||
|
||||
```typescript
|
||||
interface WorkerSystemConfig {
|
||||
/** 是否启用Worker并行处理 */
|
||||
enableWorker?: boolean;
|
||||
/** Worker数量,默认为CPU核心数,自动限制在系统最大值内 */
|
||||
workerCount?: number;
|
||||
/** 每个Worker处理的实体数量,用于控制负载分布 */
|
||||
entitiesPerWorker?: number;
|
||||
/** 系统配置数据,会传递给Worker */
|
||||
systemConfig?: any;
|
||||
/** 是否使用SharedArrayBuffer优化 */
|
||||
useSharedArrayBuffer?: boolean;
|
||||
/** 每个实体在SharedArrayBuffer中占用的Float32数量 */
|
||||
entityDataSize?: number;
|
||||
/** 最大实体数量(用于预分配SharedArrayBuffer) */
|
||||
maxEntities?: number;
|
||||
}
|
||||
```
|
||||
|
||||
### 配置建议
|
||||
|
||||
```typescript
|
||||
constructor() {
|
||||
super(matcher, {
|
||||
// 根据任务复杂度决定是否启用
|
||||
enableWorker: this.shouldUseWorker(),
|
||||
|
||||
// Worker数量:系统会自动限制在硬件支持范围内
|
||||
workerCount: 8, // 请求8个Worker,实际数量受CPU核心数限制
|
||||
|
||||
// 每个Worker处理的实体数量(可选)
|
||||
entitiesPerWorker: 200, // 精确控制负载分布
|
||||
|
||||
// 大量简单计算时启用SharedArrayBuffer
|
||||
useSharedArrayBuffer: this.entityCount > 1000,
|
||||
|
||||
// 根据实际数据结构设置
|
||||
entityDataSize: 8, // 确保与数据结构匹配
|
||||
|
||||
// 预估最大实体数量
|
||||
maxEntities: 10000,
|
||||
|
||||
// 传递给Worker的全局配置
|
||||
systemConfig: {
|
||||
gravity: 9.8,
|
||||
friction: 0.95,
|
||||
worldBounds: { width: 1920, height: 1080 }
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
private shouldUseWorker(): boolean {
|
||||
// 根据实体数量和计算复杂度决定
|
||||
return this.expectedEntityCount > 100;
|
||||
}
|
||||
|
||||
// 获取系统信息
|
||||
getSystemInfo() {
|
||||
const info = this.getWorkerInfo();
|
||||
console.log(`Worker数量: ${info.workerCount}/${info.maxSystemWorkerCount}`);
|
||||
console.log(`每Worker实体数: ${info.entitiesPerWorker || '自动分配'}`);
|
||||
console.log(`当前模式: ${info.currentMode}`);
|
||||
}
|
||||
```
|
||||
|
||||
## 处理模式
|
||||
|
||||
Worker系统支持两种处理模式:
|
||||
|
||||
### 1. 传统Worker模式
|
||||
|
||||
数据通过序列化在主线程和Worker间传递:
|
||||
|
||||
```typescript
|
||||
// 适用于:复杂计算逻辑,实体数量适中
|
||||
constructor() {
|
||||
super(matcher, {
|
||||
enableWorker: true,
|
||||
useSharedArrayBuffer: false, // 使用传统模式
|
||||
workerCount: 2
|
||||
});
|
||||
}
|
||||
|
||||
protected workerProcess(entities: EntityData[], deltaTime: number): EntityData[] {
|
||||
// 复杂的算法逻辑
|
||||
return entities.map(entity => {
|
||||
// AI决策、路径规划等复杂计算
|
||||
return this.complexAILogic(entity, deltaTime);
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
### 2. SharedArrayBuffer模式
|
||||
|
||||
零拷贝数据共享,适合大量简单计算:
|
||||
|
||||
```typescript
|
||||
// 适用于:大量实体的简单计算
|
||||
constructor() {
|
||||
super(matcher, {
|
||||
enableWorker: true,
|
||||
useSharedArrayBuffer: true, // 启用共享内存
|
||||
entityDataSize: 6,
|
||||
maxEntities: 10000
|
||||
});
|
||||
}
|
||||
|
||||
protected getSharedArrayBufferProcessFunction(): SharedArrayBufferProcessFunction {
|
||||
return function(sharedFloatArray: Float32Array, startIndex: number, endIndex: number, deltaTime: number, config: any) {
|
||||
const entitySize = 6;
|
||||
for (let i = startIndex; i < endIndex; i++) {
|
||||
const offset = i * entitySize;
|
||||
|
||||
// 读取数据
|
||||
let x = sharedFloatArray[offset];
|
||||
let y = sharedFloatArray[offset + 1];
|
||||
let vx = sharedFloatArray[offset + 2];
|
||||
let vy = sharedFloatArray[offset + 3];
|
||||
|
||||
// 物理计算
|
||||
vy += config.gravity * deltaTime;
|
||||
x += vx * deltaTime;
|
||||
y += vy * deltaTime;
|
||||
|
||||
// 写回数据
|
||||
sharedFloatArray[offset] = x;
|
||||
sharedFloatArray[offset + 1] = y;
|
||||
sharedFloatArray[offset + 2] = vx;
|
||||
sharedFloatArray[offset + 3] = vy;
|
||||
}
|
||||
};
|
||||
}
|
||||
```

||||

||||

}
|
||||
}
|
||||
```
|
||||
|
||||
## 适用场景
|
||||
|
||||
Worker系统特别适合以下场景:
|
||||
|
||||
### 1. 物理模拟
|
||||
- **重力系统**:大量实体的重力计算
|
||||
- **碰撞检测**:复杂的碰撞算法
|
||||
- **流体模拟**:粒子流体系统
|
||||
- **布料模拟**:顶点物理计算
|
||||
|
||||
### 2. AI计算
|
||||
- **路径寻找**:A*、Dijkstra等算法
|
||||
- **行为树**:复杂的AI决策逻辑
|
||||
- **群体智能**:鸟群、鱼群算法
|
||||
- **神经网络**:简单的AI推理
|
||||
|
||||
### 3. 数据处理
|
||||
- **大量实体更新**:状态机、生命周期管理
|
||||
- **统计计算**:游戏数据分析
|
||||
- **图像处理**:纹理生成、效果计算
|
||||
- **音频处理**:音效合成、频谱分析
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. Worker函数要求
|
||||
|
||||
```typescript
|
||||
// ✅ 推荐:Worker处理函数是纯函数
|
||||
protected workerProcess(entities: PhysicsData[], deltaTime: number, config: any): PhysicsData[] {
|
||||
// 只使用参数和标准JavaScript API
|
||||
return entities.map(entity => {
|
||||
// 纯计算逻辑,不依赖外部状态
|
||||
entity.y += entity.velocity * deltaTime;
|
||||
return entity;
|
||||
});
|
||||
}
|
||||
|
||||
// ❌ 避免:在Worker函数中使用外部引用
|
||||
protected workerProcess(entities: PhysicsData[], deltaTime: number): PhysicsData[] {
|
||||
// this 和外部变量在Worker中不可用
|
||||
return entities.map(entity => {
|
||||
entity.y += this.someProperty; // ❌ 错误
|
||||
return entity;
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 数据设计
|
||||
|
||||
```typescript
|
||||
// ✅ 推荐:合理的数据设计
|
||||
interface SimplePhysicsData {
|
||||
x: number;
|
||||
y: number;
|
||||
vx: number;
|
||||
vy: number;
|
||||
// 保持数据结构简单,便于序列化
|
||||
}
|
||||
|
||||
// ❌ 避免:复杂的嵌套对象
|
||||
interface ComplexData {
|
||||
transform: {
|
||||
position: { x: number; y: number };
|
||||
rotation: { angle: number };
|
||||
};
|
||||
// 复杂嵌套结构增加序列化开销
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Worker数量控制
|
||||
|
||||
```typescript
|
||||
// ✅ 推荐:灵活的Worker配置
|
||||
constructor() {
|
||||
super(matcher, {
|
||||
// 直接指定需要的Worker数量,系统会自动限制在硬件支持范围内
|
||||
workerCount: 8, // 请求8个Worker
|
||||
entitiesPerWorker: 100, // 每个Worker处理100个实体
|
||||
enableWorker: this.shouldUseWorker(), // 条件启用
|
||||
});
|
||||
}
|
||||
|
||||
private shouldUseWorker(): boolean {
|
||||
// 根据实体数量和复杂度决定是否使用Worker
|
||||
return this.expectedEntityCount > 100;
|
||||
}
|
||||
|
||||
// 获取实际使用的Worker信息
|
||||
checkWorkerConfiguration() {
|
||||
const info = this.getWorkerInfo();
|
||||
console.log(`请求Worker数量: 8`);
|
||||
console.log(`实际Worker数量: ${info.workerCount}`);
|
||||
console.log(`系统最大支持: ${info.maxSystemWorkerCount}`);
|
||||
console.log(`每Worker实体数: ${info.entitiesPerWorker || '自动分配'}`);
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 性能监控
|
||||
|
||||
```typescript
|
||||
// ✅ 推荐:性能监控
|
||||
public getPerformanceMetrics(): WorkerPerformanceMetrics {
|
||||
return {
|
||||
...this.getWorkerInfo(),
|
||||
entityCount: this.entities.length,
|
||||
averageProcessTime: this.getAverageProcessTime(),
|
||||
workerUtilization: this.getWorkerUtilization()
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
## 性能优化建议
|
||||
|
||||
### 1. 计算密集度评估
|
||||
只对计算密集型任务使用Worker,避免在简单计算上增加线程开销。
|
||||
|
||||
### 2. 数据传输优化
|
||||
- 使用SharedArrayBuffer减少序列化开销
|
||||
- 保持数据结构简单和扁平
|
||||
- 避免频繁的大数据传输
|
||||
|
||||
### 3. 降级策略
|
||||
始终提供主线程回退方案,确保在不支持Worker的环境中正常运行。
|
||||
|
||||
### 4. 内存管理
|
||||
及时清理Worker池和共享缓冲区,避免内存泄漏。
|
||||
|
||||
### 5. 负载均衡
|
||||
使用 `entitiesPerWorker` 参数精确控制负载分布,避免某些Worker空闲而其他Worker过载。

|
||||
|
||||
WorldManager 适合以下高级场景:
|
||||
- MMO 游戏服务器的多房间管理
|
||||
- 游戏大厅系统(每个游戏房间完全隔离)
|
||||
- 服务器端的多游戏实例
|
||||
- 需要完全隔离的多个游戏环境
|
||||
- 需要同时运行多个独立世界的应用
|
||||
|
||||
## 特点
|
||||
|
||||
- 多 World 管理,每个 World 完全独立
|
||||
- 每个 World 可以包含多个 Scene
|
||||
- 支持 World 的激活/停用
|
||||
- 自动清理空 World
|
||||
- World 级别的全局系统
|
||||
- 批量操作和查询
|
||||
|
||||
## 基本使用
|
||||
|
||||
### 初始化
|
||||
|
||||
WorldManager 是 Core 的内置服务,通过服务容器获取:
|
||||
|
||||
```typescript
|
||||
import { Core, WorldManager } from '@esengine/ecs-framework';
|
||||
|
||||
// 初始化 Core
|
||||
Core.create({ debug: true });
|
||||
|
||||
// 从服务容器获取 WorldManager(Core 已自动创建并注册)
|
||||
const worldManager = Core.services.resolve(WorldManager);
|
||||
```
|
||||
|
||||
### 创建 World
|
||||
|
||||
```typescript
|
||||
// 创建游戏房间 World
|
||||
const room1 = worldManager.createWorld('room_001', {
|
||||
name: 'GameRoom_001',
|
||||
maxScenes: 5,
|
||||
debug: true
|
||||
});
|
||||
|
||||
// 激活 World
|
||||
worldManager.setWorldActive('room_001', true);
|
||||
|
||||
// 创建更多房间
|
||||
const room2 = worldManager.createWorld('room_002', {
|
||||
name: 'GameRoom_002',
|
||||
maxScenes: 5
|
||||
});
|
||||
|
||||
worldManager.setWorldActive('room_002', true);
|
||||
```
|
||||
|
||||
### 游戏循环
|
||||
|
||||
在游戏循环中更新所有活跃的 World:
|
||||
|
||||
```typescript
|
||||
function gameLoop(deltaTime: number) {
|
||||
Core.update(deltaTime); // 更新全局服务
|
||||
worldManager.updateAll(); // 更新所有活跃的 World
|
||||
}
|
||||
|
||||
// 启动游戏循环
|
||||
let lastTime = 0;
|
||||
setInterval(() => {
|
||||
const currentTime = Date.now();
|
||||
const deltaTime = (currentTime - lastTime) / 1000;
|
||||
lastTime = currentTime;
|
||||
|
||||
gameLoop(deltaTime);
|
||||
}, 16); // 60 FPS
|
||||
```
|
||||
|
||||
## World 管理
|
||||
|
||||
### 创建 World
|
||||
|
||||
```typescript
|
||||
// 基本创建
|
||||
const world = worldManager.createWorld('worldId');
|
||||
|
||||
// 带配置创建
|
||||
const world = worldManager.createWorld('worldId', {
|
||||
name: 'MyWorld',
|
||||
maxScenes: 10,
|
||||
autoCleanup: true,
|
||||
debug: true
|
||||
});
|
||||
```
|
||||
|
||||
**配置选项(IWorldConfig)**:
|
||||
- `name?: string` - World 名称
|
||||
- `maxScenes?: number` - 最大场景数量限制(默认 10)
|
||||
- `autoCleanup?: boolean` - 是否自动清理空场景(默认 true)
|
||||
- `debug?: boolean` - 是否启用调试模式(默认 false)
|
||||
|
||||
### 获取 World
|
||||
|
||||
```typescript
|
||||
// 通过 ID 获取
|
||||
const world = worldManager.getWorld('room_001');
|
||||
if (world) {
|
||||
console.log(`World: ${world.name}`);
|
||||
}
|
||||
|
||||
// 获取所有 World
|
||||
const allWorlds = worldManager.getAllWorlds();
|
||||
console.log(`共有 ${allWorlds.length} 个 World`);
|
||||
|
||||
// 获取所有 World ID
|
||||
const worldIds = worldManager.getWorldIds();
|
||||
console.log('World 列表:', worldIds);
|
||||
|
||||
// 通过名称查找
|
||||
const world = worldManager.findWorldByName('GameRoom_001');
|
||||
```
|
||||
|
||||
### 激活和停用 World
|
||||
|
||||
```typescript
|
||||
// 激活 World(开始运行和更新)
|
||||
worldManager.setWorldActive('room_001', true);
|
||||
|
||||
// 停用 World(停止更新但保留数据)
|
||||
worldManager.setWorldActive('room_001', false);
|
||||
|
||||
// 检查 World 是否激活
|
||||
if (worldManager.isWorldActive('room_001')) {
|
||||
console.log('房间正在运行');
|
||||
}
|
||||
|
||||
// 获取所有活跃的 World
|
||||
const activeWorlds = worldManager.getActiveWorlds();
|
||||
console.log(`当前有 ${activeWorlds.length} 个活跃 World`);
|
||||
```
|
||||
|
||||
### 移除 World
|
||||
|
||||
```typescript
|
||||
// 移除 World(会自动停用并销毁)
|
||||
const removed = worldManager.removeWorld('room_001');
|
||||
if (removed) {
|
||||
console.log('World 已移除');
|
||||
}
|
||||
```
|
||||
|
||||
## World 中的场景管理
|
||||
|
||||
每个 World 可以包含多个 Scene 并独立管理它们的生命周期。
|
||||
|
||||
### 创建场景
|
||||
|
||||
```typescript
|
||||
const world = worldManager.getWorld('room_001');
|
||||
if (!world) return;
|
||||
|
||||
// 创建场景
|
||||
const mainScene = world.createScene('main', new MainScene());
|
||||
const uiScene = world.createScene('ui', new UIScene());
|
||||
const hudScene = world.createScene('hud', new HUDScene());
|
||||
|
||||
// 激活场景
|
||||
world.setSceneActive('main', true);
|
||||
world.setSceneActive('ui', true);
|
||||
world.setSceneActive('hud', false);
|
||||
```
|
||||
|
||||
### 查询场景
|
||||
|
||||
```typescript
|
||||
// 获取特定场景
|
||||
const mainScene = world.getScene<MainScene>('main');
|
||||
if (mainScene) {
|
||||
console.log(`场景名称: ${mainScene.name}`);
|
||||
}
|
||||
|
||||
// 获取所有场景
|
||||
const allScenes = world.getAllScenes();
|
||||
console.log(`World 中共有 ${allScenes.length} 个场景`);
|
||||
|
||||
// 获取所有场景 ID
|
||||
const sceneIds = world.getSceneIds();
|
||||
console.log('场景列表:', sceneIds);
|
||||
|
||||
// 获取活跃场景数量
|
||||
const activeCount = world.getActiveSceneCount();
|
||||
console.log(`当前有 ${activeCount} 个活跃场景`);
|
||||
|
||||
// 检查场景是否激活
|
||||
if (world.isSceneActive('main')) {
|
||||
console.log('主场景正在运行');
|
||||
}
|
||||
```
|
||||
|
||||
### 场景切换
|
||||
|
||||
World 支持多场景同时运行,也支持场景切换:
|
||||
|
||||
```typescript
|
||||
class GameWorld {
|
||||
private world: World;
|
||||
|
||||
constructor(worldManager: WorldManager) {
|
||||
this.world = worldManager.createWorld('game', {
|
||||
name: 'GameWorld',
|
||||
maxScenes: 5
|
||||
});
|
||||
|
||||
// 创建所有场景
|
||||
this.world.createScene('menu', new MenuScene());
|
||||
this.world.createScene('game', new GameScene());
|
||||
this.world.createScene('pause', new PauseScene());
|
||||
this.world.createScene('gameover', new GameOverScene());
|
||||
|
||||
// 激活 World
|
||||
worldManager.setWorldActive('game', true);
|
||||
}
|
||||
|
||||
public showMenu(): void {
|
||||
this.deactivateAllScenes();
|
||||
this.world.setSceneActive('menu', true);
|
||||
}
|
||||
|
||||
public startGame(): void {
|
||||
this.deactivateAllScenes();
|
||||
this.world.setSceneActive('game', true);
|
||||
}
|
||||
|
||||
public pauseGame(): void {
|
||||
// 游戏场景继续存在但停止更新
|
||||
this.world.setSceneActive('game', false);
|
||||
// 显示暂停界面
|
||||
this.world.setSceneActive('pause', true);
|
||||
}
|
||||
|
||||
public resumeGame(): void {
|
||||
this.world.setSceneActive('pause', false);
|
||||
this.world.setSceneActive('game', true);
|
||||
}
|
||||
|
||||
public showGameOver(): void {
|
||||
this.deactivateAllScenes();
|
||||
this.world.setSceneActive('gameover', true);
|
||||
}
|
||||
|
||||
private deactivateAllScenes(): void {
|
||||
const sceneIds = this.world.getSceneIds();
|
||||
sceneIds.forEach(id => this.world.setSceneActive(id, false));
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 移除场景
|
||||
|
||||
```typescript
|
||||
// 移除不再需要的场景
|
||||
const removed = world.removeScene('oldScene');
|
||||
if (removed) {
|
||||
console.log('场景已移除');
|
||||
}
|
||||
|
||||
// 场景会自动调用 end() 方法进行清理
|
||||
```
|
||||
|
||||
## 全局系统
|
||||
|
||||
World 支持全局系统,这些系统在 World 级别运行,不依赖特定 Scene。
|
||||
|
||||
### 定义全局系统
|
||||
|
||||
```typescript
|
||||
import { IGlobalSystem } from '@esengine/ecs-framework';
|
||||
|
||||
// 网络系统(World 级别)
|
||||
class NetworkSystem implements IGlobalSystem {
|
||||
readonly name = 'NetworkSystem';
|
||||
|
||||
private connectionId: string;
|
||||
|
||||
constructor(connectionId: string) {
|
||||
this.connectionId = connectionId;
|
||||
}
|
||||
|
||||
initialize(): void {
|
||||
console.log(`网络系统初始化: ${this.connectionId}`);
|
||||
// 建立网络连接
|
||||
}
|
||||
|
||||
update(deltaTime?: number): void {
|
||||
// 处理网络消息,不依赖任何 Scene
|
||||
// 接收和发送网络包
|
||||
}
|
||||
|
||||
destroy(): void {
|
||||
console.log(`网络系统销毁: ${this.connectionId}`);
|
||||
// 关闭网络连接
|
||||
}
|
||||
}
|
||||
|
||||
// 物理系统(World 级别)
|
||||
class PhysicsSystem implements IGlobalSystem {
|
||||
readonly name = 'PhysicsSystem';
|
||||
|
||||
initialize(): void {
|
||||
console.log('物理系统初始化');
|
||||
}
|
||||
|
||||
update(deltaTime?: number): void {
|
||||
// 物理模拟,作用于 World 中所有场景
|
||||
}
|
||||
|
||||
destroy(): void {
|
||||
console.log('物理系统销毁');
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 使用全局系统
|
||||
|
||||
```typescript
|
||||
const world = worldManager.getWorld('room_001');
|
||||
if (!world) return;
|
||||
|
||||
// 添加全局系统
|
||||
const networkSystem = world.addGlobalSystem(new NetworkSystem('conn_001'));
|
||||
const physicsSystem = world.addGlobalSystem(new PhysicsSystem());
|
||||
|
||||
// 获取全局系统
|
||||
const network = world.getGlobalSystem(NetworkSystem);
|
||||
if (network) {
|
||||
console.log('找到网络系统');
|
||||
}
|
||||
|
||||
// 移除全局系统
|
||||
world.removeGlobalSystem(networkSystem);
|
||||
```
|
||||
|
||||
## 批量操作
|
||||
|
||||
### 更新所有 World
|
||||
|
||||
```typescript
|
||||
// 更新所有活跃的 World(应该在游戏循环中调用)
|
||||
worldManager.updateAll();
|
||||
|
||||
// 这会自动更新每个 World 的:
|
||||
// 1. 全局系统
|
||||
// 2. 所有活跃场景
|
||||
```
|
||||
|
||||
### 启动和停止
|
||||
|
||||
```typescript
|
||||
// 启动所有 World
|
||||
worldManager.startAll();
|
||||
|
||||
// 停止所有 World
|
||||
worldManager.stopAll();
|
||||
|
||||
// 检查是否正在运行
|
||||
if (worldManager.isRunning) {
|
||||
console.log('WorldManager 正在运行');
|
||||
}
|
||||
```
|
||||
|
||||
### 查找 World
|
||||
|
||||
```typescript
|
||||
// 使用条件查找
|
||||
const emptyWorlds = worldManager.findWorlds(world => {
|
||||
return world.sceneCount === 0;
|
||||
});
|
||||
|
||||
// 查找活跃的 World
|
||||
const activeWorlds = worldManager.findWorlds(world => {
|
||||
return world.isActive;
|
||||
});
|
||||
|
||||
// 查找特定名称的 World
|
||||
const world = worldManager.findWorldByName('GameRoom_001');
|
||||
```
|
||||
|
||||
## 统计和监控
|
||||
|
||||
### 获取统计信息
|
||||
|
||||
```typescript
|
||||
const stats = worldManager.getStats();
|
||||
|
||||
console.log(`总 World 数: ${stats.totalWorlds}`);
|
||||
console.log(`活跃 World 数: ${stats.activeWorlds}`);
|
||||
console.log(`总场景数: ${stats.totalScenes}`);
|
||||
console.log(`总实体数: ${stats.totalEntities}`);
|
||||
console.log(`总系统数: ${stats.totalSystems}`);
|
||||
|
||||
// 查看每个 World 的详细信息
|
||||
stats.worlds.forEach(worldInfo => {
|
||||
console.log(`World: ${worldInfo.name}`);
|
||||
console.log(` 场景数: ${worldInfo.sceneCount}`);
|
||||
console.log(` 是否活跃: ${worldInfo.isActive}`);
|
||||
});
|
||||
```
|
||||
|
||||
### 获取详细状态
|
||||
|
||||
```typescript
|
||||
const status = worldManager.getDetailedStatus();
|
||||
|
||||
// 包含所有 World 的详细状态
|
||||
status.worlds.forEach(worldStatus => {
|
||||
console.log(`World ID: ${worldStatus.id}`);
|
||||
console.log(`状态:`, worldStatus.status);
|
||||
});
|
||||
```
|
||||
|
||||
## 自动清理
|
||||
|
||||
WorldManager 支持自动清理空的 World。
|
||||
|
||||
### 配置清理
|
||||
|
||||
```typescript
|
||||
// 创建带清理配置的 WorldManager
|
||||
const worldManager = Core.services.resolve(WorldManager);
|
||||
|
||||
// WorldManager 的配置在 Core 中设置:
|
||||
// {
|
||||
// maxWorlds: 50,
|
||||
// autoCleanup: true,
|
||||
// cleanupFrameInterval: 1800 // 间隔多少帧清理闲置 World
|
||||
// }
|
||||
```
|
||||
|
||||
### 手动清理
|
||||
|
||||
```typescript
|
||||
// 手动触发清理
|
||||
const cleanedCount = worldManager.cleanup();
|
||||
console.log(`清理了 ${cleanedCount} 个 World`);
|
||||
```
|
||||
|
||||
**清理条件**:
|
||||
- World 未激活
|
||||
- 没有 Scene 或所有 Scene 都是空的
|
||||
- 创建时间超过 10 分钟
|
||||
|
||||

### MMO 游戏房间系统
|
||||
|
||||
```typescript
|
||||
import { Core, WorldManager, Scene, World } from '@esengine/ecs-framework';
|
||||
|
||||
// 初始化

|
||||
this.rooms.delete(roomId);
|

}
|

// 获取房间列表
|

const world = this.rooms.get(roomId);
|

return world?.getStats();
|

}
|
||||
}
|
||||
|
||||
// 使用房间管理器
|
||||
const roomManager = new RoomManager(worldManager);
|
||||
|
||||
// 创建多个游戏房间
|
||||
roomManager.createRoom('room_001', 4);
|
||||
roomManager.createRoom('room_002', 4);
|
||||
roomManager.createRoom('room_003', 2);
|
||||
|
||||
// 玩家加入
|
||||
roomManager.joinRoom('room_001', 'player_1');
|
||||
roomManager.joinRoom('room_001', 'player_2');
|
||||
|
||||
// 开始游戏
|
||||
roomManager.startGame('room_001');
|
||||
|
||||
// 游戏循环
|
||||
function gameLoop(deltaTime: number) {
|
||||
Core.update(deltaTime);
|
||||
worldManager.updateAll(); // 更新所有房间
|
||||
}
|
||||
|
||||
// 定期清理空房间
|
||||
setInterval(() => {
|
||||
const stats = worldManager.getStats();
|
||||
console.log(`当前房间数: ${stats.totalWorlds}`);
|
||||
console.log(`活跃房间数: ${stats.activeWorlds}`);
|
||||
|
||||
worldManager.cleanup();
|
||||
}, 60000); // 每分钟清理一次
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 合理的 World 粒度
|
||||
|
||||
```typescript
|
||||
// 推荐:每个独立环境一个 World
|
||||
const room1 = worldManager.createWorld('room_1'); // 游戏房间1
|
||||
const room2 = worldManager.createWorld('room_2'); // 游戏房间2
|
||||
|
||||
// 不推荐:过度使用 World
|
||||
const world1 = worldManager.createWorld('ui'); // UI 不需要独立 World
|
||||
const world2 = worldManager.createWorld('menu'); // 菜单不需要独立 World
|
||||
```
|
||||
|
||||
### 2. 使用全局系统处理跨场景逻辑
|
||||
|
||||
```typescript
|
||||
// 推荐:World 级别的系统
|
||||
class NetworkSystem implements IGlobalSystem {
|
||||
update() {
|
||||
// 网络处理不依赖场景
|
||||
}
|
||||
}
|
||||
|
||||
// 不推荐:在每个场景中重复创建
|
||||
class GameScene extends Scene {
|
||||
initialize() {
|
||||
this.addSystem(new NetworkSystem()); // 不应该在场景级别
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 及时清理不用的 World
|
||||
|
||||
```typescript
|
||||
// 推荐:玩家离开时清理房间
|
||||
function onPlayerLeave(roomId: string) {
|
||||
const world = worldManager.getWorld(roomId);
|
||||
if (world && world.sceneCount === 0) {
|
||||
worldManager.removeWorld(roomId);
|
||||
}
|
||||
}
|
||||
|
||||
// 或使用自动清理
|
||||
worldManager.cleanup();
|
||||
```
|
||||
|
||||
### 4. 监控资源使用
|
||||
|
||||
```typescript
|
||||
// 定期检查资源使用情况
|
||||
setInterval(() => {
|
||||
const stats = worldManager.getStats();
|
||||
|
||||
if (stats.totalWorlds > 100) {
|
||||
console.warn('World 数量过多,考虑清理');
|
||||
worldManager.cleanup();
|
||||
}
|
||||
|
||||
if (stats.totalEntities > 10000) {
|
||||
console.warn('实体数量过多,检查是否有泄漏');
|
||||
}
|
||||
}, 30000);
|
||||
```
|
||||
|
||||
## 与 SceneManager 的对比
|
||||
|
||||
| 特性 | SceneManager | WorldManager |
|
||||
|------|--------------|--------------|
|
||||
| 适用场景 | 95% 的游戏应用 | 高级多世界隔离场景 |
|
||||
| 复杂度 | 简单 | 复杂 |
|
||||
| 场景数量 | 单场景(可切换) | 多 World,每个 World 多场景 |
|
||||
| 场景隔离 | 无(场景切换) | 完全隔离(每个 World 独立) |
|
||||
| 性能开销 | 最小 | 较高 |
|
||||
| 全局系统 | 无 | 支持(World 级别) |
|
||||
| 使用示例 | 单人游戏、移动游戏 | MMO 服务器、游戏房间系统 |
|
||||
|
||||
**何时使用 WorldManager**:
|
||||
- MMO 游戏服务器(每个房间一个 World)
|
||||
- 游戏大厅系统(每个游戏房间完全隔离)
|
||||
- 需要运行多个完全独立的游戏实例
|
||||
- 服务器端模拟多个游戏世界
|
||||
|
||||
**何时使用 SceneManager**:
|
||||
- 单人游戏
|
||||
- 简单的多人游戏
|
||||
- 移动游戏
|
||||
- 场景之间需要切换但不需要同时运行
|
||||
|
||||
## 架构层次
|
||||
|
||||
WorldManager 在 ECS Framework 中的位置:
|
||||
|
||||
```
|
||||
Core (全局服务)
|
||||
└── WorldManager (世界管理)
|
||||
├── World 1 (游戏房间1)
|
||||
│ ├── GlobalSystem (全局系统)
|
||||
│ ├── Scene 1 (场景1)
|
||||
│ │ ├── EntitySystem
|
||||
│ │ ├── Entity
|
||||
│ │ └── Component
|
||||
│ └── Scene 2 (场景2)
|
||||
├── World 2 (游戏房间2)
|
||||
│ ├── GlobalSystem
|
||||
│ └── Scene 1
|
||||
└── World 3 (游戏房间3)
|
||||
```
|
||||
|
||||
WorldManager 为需要多世界隔离的高级应用提供了强大的管理能力。如果你的应用不需要多世界隔离,建议使用更简单的 [SceneManager](./scene-manager.md)。
