# 定时器系统 (Timer)
|
||||
|
||||
`@esengine/timer` 提供了一个灵活的定时器和冷却系统,用于游戏中的延迟执行、重复任务、技能冷却等场景。
|
||||
|
||||
## 安装
|
||||
|
||||
```bash
|
||||
npm install @esengine/timer
|
||||
```
|
||||
|
||||
## 快速开始
|
||||
|
||||
```typescript
|
||||
import { createTimerService } from '@esengine/timer';
|
||||
|
||||
// 创建定时器服务
|
||||
const timerService = createTimerService();
|
||||
|
||||
// 一次性定时器(1秒后执行)
|
||||
const handle = timerService.schedule('myTimer', 1000, () => {
|
||||
console.log('Timer fired!');
|
||||
});
|
||||
|
||||
// 重复定时器(每100毫秒执行)
|
||||
timerService.scheduleRepeating('heartbeat', 100, () => {
|
||||
console.log('Tick');
|
||||
});
|
||||
|
||||
// 冷却系统(5秒冷却)
|
||||
timerService.startCooldown('skill_fireball', 5000);
|
||||
|
||||
if (timerService.isCooldownReady('skill_fireball')) {
|
||||
// 可以使用技能
|
||||
useFireball();
|
||||
timerService.startCooldown('skill_fireball', 5000);
|
||||
}
|
||||
|
||||
// 游戏循环中更新
|
||||
function gameLoop(deltaTime: number) {
|
||||
timerService.update(deltaTime);
|
||||
}
|
||||
```
|
||||
|
||||
## 核心概念
|
||||
|
||||
### 定时器 vs 冷却
|
||||
|
||||
| 特性 | 定时器 (Timer) | 冷却 (Cooldown) |
|
||||
|------|---------------|-----------------|
|
||||
| 用途 | 延迟执行代码 | 限制操作频率 |
|
||||
| 回调 | 有回调函数 | 无回调函数 |
|
||||
| 重复 | 支持重复执行 | 一次性 |
|
||||
| 查询 | 查询剩余时间 | 查询进度/是否就绪 |
|
||||
|
||||
### TimerHandle
|
||||
|
||||
调度定时器后返回的句柄对象,用于控制定时器:
|
||||
|
||||
```typescript
|
||||
interface TimerHandle {
|
||||
readonly id: string; // 定时器 ID
|
||||
readonly isValid: boolean; // 是否有效(未被取消)
|
||||
cancel(): void; // 取消定时器
|
||||
}
|
||||
```
|
||||
|
||||
### TimerInfo
|
||||
|
||||
定时器信息对象:
|
||||
|
||||
```typescript
|
||||
interface TimerInfo {
|
||||
readonly id: string; // 定时器 ID
|
||||
readonly remaining: number; // 剩余时间(毫秒)
|
||||
readonly repeating: boolean; // 是否重复执行
|
||||
readonly interval?: number; // 间隔时间(仅重复定时器)
|
||||
}
|
||||
```
|
||||
|
||||
### CooldownInfo
|
||||
|
||||
冷却信息对象:
|
||||
|
||||
```typescript
|
||||
interface CooldownInfo {
|
||||
readonly id: string; // 冷却 ID
|
||||
readonly duration: number; // 总持续时间(毫秒)
|
||||
readonly remaining: number; // 剩余时间(毫秒)
|
||||
readonly progress: number; // 进度(0-1,0=刚开始,1=结束)
|
||||
readonly isReady: boolean; // 是否已就绪
|
||||
}
|
||||
```
|
||||
|
||||
## API 参考
|
||||
|
||||
### createTimerService
|
||||
|
||||
```typescript
|
||||
function createTimerService(config?: TimerServiceConfig): ITimerService
|
||||
```
|
||||
|
||||
**配置选项:**
|
||||
|
||||
| 属性 | 类型 | 默认值 | 描述 |
|
||||
|------|------|--------|------|
|
||||
| `maxTimers` | `number` | `0` | 最大定时器数量(0 表示无限制) |
|
||||
| `maxCooldowns` | `number` | `0` | 最大冷却数量(0 表示无限制) |
|
||||
|
||||
### 定时器 API
|
||||
|
||||
#### schedule
|
||||
|
||||
调度一次性定时器:
|
||||
|
||||
```typescript
|
||||
const handle = timerService.schedule('explosion', 2000, () => {
|
||||
createExplosion();
|
||||
});
|
||||
|
||||
// 提前取消
|
||||
handle.cancel();
|
||||
```
|
||||
|
||||
#### scheduleRepeating
|
||||
|
||||
调度重复定时器:
|
||||
|
||||
```typescript
|
||||
// 每秒执行
|
||||
timerService.scheduleRepeating('regen', 1000, () => {
|
||||
player.hp += 5;
|
||||
});
|
||||
|
||||
// 立即执行一次,然后每秒重复
|
||||
timerService.scheduleRepeating('tick', 1000, () => {
|
||||
console.log('Tick');
|
||||
}, true); // immediate = true
|
||||
```
|
||||
|
||||
#### cancel / cancelById
|
||||
|
||||
取消定时器:
|
||||
|
||||
```typescript
|
||||
// 通过句柄取消
|
||||
handle.cancel();
|
||||
// 或
|
||||
timerService.cancel(handle);
|
||||
|
||||
// 通过 ID 取消
|
||||
timerService.cancelById('regen');
|
||||
```
|
||||
|
||||
#### hasTimer
|
||||
|
||||
检查定时器是否存在:
|
||||
|
||||
```typescript
|
||||
if (timerService.hasTimer('explosion')) {
|
||||
console.log('Explosion is pending');
|
||||
}
|
||||
```
|
||||
|
||||
#### getTimerInfo
|
||||
|
||||
获取定时器信息:
|
||||
|
||||
```typescript
|
||||
const info = timerService.getTimerInfo('explosion');
|
||||
if (info) {
|
||||
console.log(`剩余时间: ${info.remaining}ms`);
|
||||
console.log(`是否重复: ${info.repeating}`);
|
||||
}
|
||||
```
|
||||
|
||||
### 冷却 API
|
||||
|
||||
#### startCooldown
|
||||
|
||||
开始冷却:
|
||||
|
||||
```typescript
|
||||
// 5秒冷却
|
||||
timerService.startCooldown('skill_fireball', 5000);
|
||||
```
|
||||
|
||||
#### isCooldownReady / isOnCooldown
|
||||
|
||||
检查冷却状态:
|
||||
|
||||
```typescript
|
||||
if (timerService.isCooldownReady('skill_fireball')) {
|
||||
// 可以使用技能
|
||||
castFireball();
|
||||
timerService.startCooldown('skill_fireball', 5000);
|
||||
} else {
|
||||
console.log('技能还在冷却中');
|
||||
}
|
||||
|
||||
// 或使用 isOnCooldown
|
||||
if (timerService.isOnCooldown('skill_fireball')) {
|
||||
console.log('冷却中...');
|
||||
}
|
||||
```
|
||||
|
||||
#### getCooldownProgress / getCooldownRemaining
|
||||
|
||||
获取冷却进度:
|
||||
|
||||
```typescript
|
||||
// 进度 0-1(0=刚开始,1=完成)
|
||||
const progress = timerService.getCooldownProgress('skill_fireball');
|
||||
console.log(`冷却进度: ${(progress * 100).toFixed(0)}%`);
|
||||
|
||||
// 剩余时间(毫秒)
|
||||
const remaining = timerService.getCooldownRemaining('skill_fireball');
|
||||
console.log(`剩余时间: ${(remaining / 1000).toFixed(1)}s`);
|
||||
```
|
||||
|
||||
#### getCooldownInfo
|
||||
|
||||
获取完整冷却信息:
|
||||
|
||||
```typescript
|
||||
const info = timerService.getCooldownInfo('skill_fireball');
|
||||
if (info) {
|
||||
console.log(`总时长: ${info.duration}ms`);
|
||||
console.log(`剩余: ${info.remaining}ms`);
|
||||
console.log(`进度: ${info.progress}`);
|
||||
console.log(`就绪: ${info.isReady}`);
|
||||
}
|
||||
```
|
||||
|
||||
#### resetCooldown / clearAllCooldowns
|
||||
|
||||
重置冷却:
|
||||
|
||||
```typescript
|
||||
// 重置单个冷却
|
||||
timerService.resetCooldown('skill_fireball');
|
||||
|
||||
// 清除所有冷却(例如角色复活时)
|
||||
timerService.clearAllCooldowns();
|
||||
```
|
||||
|
||||
### 生命周期
|
||||
|
||||
#### update
|
||||
|
||||
更新定时器服务(需要每帧调用):
|
||||
|
||||
```typescript
|
||||
function gameLoop(deltaTime: number) {
|
||||
// deltaTime 单位是毫秒
|
||||
timerService.update(deltaTime);
|
||||
}
|
||||
```
|
||||
|
||||
#### clear
|
||||
|
||||
清除所有定时器和冷却:
|
||||
|
||||
```typescript
|
||||
timerService.clear();
|
||||
```
|
||||
|
||||
### 调试属性
|
||||
|
||||
```typescript
|
||||
// 获取活跃定时器数量
|
||||
console.log(timerService.activeTimerCount);
|
||||
|
||||
// 获取活跃冷却数量
|
||||
console.log(timerService.activeCooldownCount);
|
||||
|
||||
// 获取所有活跃定时器 ID
|
||||
const timerIds = timerService.getActiveTimerIds();
|
||||
|
||||
// 获取所有活跃冷却 ID
|
||||
const cooldownIds = timerService.getActiveCooldownIds();
|
||||
```
|
||||
|
||||
## 实际示例
|
||||
|
||||
### 技能冷却系统
|
||||
|
||||
```typescript
|
||||
import { createTimerService, type ITimerService } from '@esengine/timer';
|
||||
|
||||
class SkillSystem {
|
||||
private timerService: ITimerService;
|
||||
private skills: Map<string, SkillData> = new Map();
|
||||
|
||||
constructor() {
|
||||
this.timerService = createTimerService();
|
||||
}
|
||||
|
||||
registerSkill(id: string, data: SkillData): void {
|
||||
this.skills.set(id, data);
|
||||
}
|
||||
|
||||
useSkill(skillId: string): boolean {
|
||||
const skill = this.skills.get(skillId);
|
||||
if (!skill) return false;
|
||||
|
||||
// 检查冷却
|
||||
if (!this.timerService.isCooldownReady(skillId)) {
|
||||
const remaining = this.timerService.getCooldownRemaining(skillId);
|
||||
console.log(`技能 ${skillId} 冷却中,剩余 ${remaining}ms`);
|
||||
return false;
|
||||
}
|
||||
|
||||
// 使用技能
|
||||
this.executeSkill(skill);
|
||||
|
||||
// 开始冷却
|
||||
this.timerService.startCooldown(skillId, skill.cooldown);
|
||||
return true;
|
||||
}
|
||||
|
||||
getSkillCooldownProgress(skillId: string): number {
|
||||
return this.timerService.getCooldownProgress(skillId);
|
||||
}
|
||||
|
||||
update(dt: number): void {
|
||||
this.timerService.update(dt);
|
||||
}
|
||||
}
|
||||
|
||||
interface SkillData {
|
||||
cooldown: number;
|
||||
// ... other properties
|
||||
}
|
||||
```
|
||||
|
||||
### 延迟和定时效果
|
||||
|
||||
```typescript
|
||||
class EffectSystem {
|
||||
private timerService: ITimerService;
|
||||
|
||||
constructor(timerService: ITimerService) {
|
||||
this.timerService = timerService;
|
||||
}
|
||||
|
||||
// 延迟爆炸
|
||||
scheduleExplosion(position: { x: number; y: number }, delay: number): void {
|
||||
this.timerService.schedule(`explosion_${Date.now()}`, delay, () => {
|
||||
this.createExplosion(position);
|
||||
});
|
||||
}
|
||||
|
||||
// DOT 伤害(每秒造成伤害)
|
||||
applyDOT(target: Entity, damage: number, duration: number): void {
|
||||
const dotId = `dot_${target.id}_${Date.now()}`;
|
||||
let elapsed = 0;
|
||||
|
||||
this.timerService.scheduleRepeating(dotId, 1000, () => {
|
||||
elapsed += 1000;
|
||||
target.takeDamage(damage);
|
||||
|
||||
if (elapsed >= duration) {
|
||||
this.timerService.cancelById(dotId);
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
// BUFF 效果(持续一段时间)
|
||||
applyBuff(target: Entity, buffId: string, duration: number): void {
|
||||
target.addBuff(buffId);
|
||||
|
||||
this.timerService.schedule(`buff_expire_${buffId}`, duration, () => {
|
||||
target.removeBuff(buffId);
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 与 ECS 集成
|
||||
|
||||
```typescript
|
||||
import { Component, EntitySystem, Matcher } from '@esengine/ecs-framework';
|
||||
import { createTimerService, type ITimerService } from '@esengine/timer';
|
||||
|
||||
// 定时器组件
|
||||
class TimerComponent extends Component {
|
||||
timerService: ITimerService;
|
||||
|
||||
constructor() {
|
||||
super();
|
||||
this.timerService = createTimerService();
|
||||
}
|
||||
}
|
||||
|
||||
// 定时器系统
|
||||
class TimerSystem extends EntitySystem {
|
||||
constructor() {
|
||||
super(Matcher.all(TimerComponent));
|
||||
}
|
||||
|
||||
protected processEntity(entity: Entity, dt: number): void {
|
||||
const timer = entity.getComponent(TimerComponent);
|
||||
timer.timerService.update(dt);
|
||||
}
|
||||
}
|
||||
|
||||
// 冷却组件(用于共享冷却)
|
||||
class CooldownComponent extends Component {
|
||||
constructor(public timerService: ITimerService) {
|
||||
super();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 蓝图节点
|
||||
|
||||
Timer 模块提供了可视化脚本支持的蓝图节点:
|
||||
|
||||
### 冷却节点
|
||||
|
||||
- `StartCooldown` - 开始冷却
|
||||
- `IsCooldownReady` - 检查冷却是否就绪
|
||||
- `GetCooldownProgress` - 获取冷却进度
|
||||
- `GetCooldownInfo` - 获取详细冷却信息
|
||||
- `ResetCooldown` - 重置冷却
|
||||
|
||||
### 定时器节点
|
||||
|
||||
- `HasTimer` - 检查定时器是否存在
|
||||
- `CancelTimer` - 取消定时器
|
||||
- `GetTimerRemaining` - 获取定时器剩余时间
|
||||
|
||||
## 服务令牌
|
||||
|
||||
在依赖注入场景中使用:
|
||||
|
||||
```typescript
|
||||
import { TimerServiceToken, createTimerService } from '@esengine/timer';
|
||||
|
||||
// 注册服务
|
||||
services.register(TimerServiceToken, createTimerService());
|
||||
|
||||
// 获取服务
|
||||
const timerService = services.get(TimerServiceToken);
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
1. **使用有意义的 ID**:使用描述性的 ID 便于调试和管理
|
||||
```typescript
|
||||
// 好
|
||||
timerService.startCooldown('skill_fireball', 5000);
|
||||
|
||||
// 不好
|
||||
timerService.startCooldown('cd1', 5000);
|
||||
```
|
||||
|
||||
2. **避免重复 ID**:相同 ID 的定时器会覆盖之前的
|
||||
```typescript
|
||||
// 使用唯一 ID
|
||||
const uniqueId = `explosion_${entity.id}_${Date.now()}`;
|
||||
timerService.schedule(uniqueId, 1000, callback);
|
||||
```
|
||||
|
||||
3. **及时清理**:在适当时机清理不需要的定时器和冷却
|
||||
```typescript
|
||||
// 实体销毁时
|
||||
onDestroy() {
|
||||
this.timerService.cancelById(this.timerId);
|
||||
}
|
||||
```
|
||||
|
||||
4. **配置限制**:在生产环境考虑设置最大数量限制
|
||||
```typescript
|
||||
const timerService = createTimerService({
|
||||
maxTimers: 1000,
|
||||
maxCooldowns: 500
|
||||
});
|
||||
```
