BehaviorTree,
Action,
Condition,
Sequence,
Selector,
Status
BehaviorTree, Status, Action, Condition,
Sequence, Selector
} from 'kunpocc-behaviortree';
// 定义AI角色

// 创建行动节点
const flee = new Action(() => {
console.log("逃跑!");
return Status.SUCCESS;
});
const attack = new Action(() => {
console.log("攻击!");
return Status.SUCCESS;
});
// 构建行为树:生命值低时逃跑,否则攻击
const tree = new BehaviorTree(character,
// 创建行为树
const tree = new BehaviorTree(enemy,
new Selector(
new Sequence(isHealthLow, flee),
new Sequence(hasWeapon, attack)
// 生命值低时逃跑
new Sequence(
new Condition((node) => {
const entity = node.getEntity<Enemy>();
return entity.health < 50;
}),
new Action((node) => {
console.log("血量低,逃跑!");
return Status.SUCCESS;
})
),
// 否则攻击
new Action((node) => {
console.log("发起攻击!");
return Status.SUCCESS;
})
)
);
// 执行行为树
tree.tick(); // 输出: "攻击"
// 执行
tree.tick(); // 输出: "血量低,逃跑"
```
#### 基本概念
## 核心概念
1. 节点状态
### 状态类型
```typescript
enum Status {
SUCCESS, // 成功
@@ -78,110 +80,460 @@ enum Status {
}
```
2. 节点类型
- **动作节点 (Action)**:执行具体行为的叶子节点
- **组合节点 (Composite)**:控制子节点执行顺序的节点
- **条件节点 (Condition)**:判断条件的节点
- **装饰节点 (Decorator)**:修饰其他节点行为的节点
### 节点类型
- **组合节点**: 控制子节点执行逻辑Sequence、Selector、Parallel等
- **装饰节点**: 修饰单个子节点Inverter、Repeat、Limit等
- **叶子节点**: 执行具体逻辑Action、Condition、Wait等
#### 常用节点
## 节点详解
1. 组合节点
### 组合节点 (Composite)
#### Sequence - 顺序节点
按顺序执行子节点,全部成功才成功:
```typescript
// 顺序节点:按顺序执行所有子节点,直到遇到失败或运行中的节点
new Sequence(childNode1, childNode2, childNode3);
// 选择节点:选择第一个成功或运行中的子节点
new Selector(childNode1, childNode2, childNode3);
// 并行节点:同时执行所有子节点,全部成功才成功
new Parallel(childNode1, childNode2, childNode3);
// 并行任一成功节点:同时执行所有子节点,任一成功即成功
new ParallelAnySuccess(childNode1, childNode2, childNode3);
// 记忆顺序节点:记住上次执行的位置
new MemSequence(childNode1, childNode2, childNode3);
// 记忆选择节点:记住上次执行的位置
new MemSelector(childNode1, childNode2, childNode3);
// 随机选择节点:随机选择一个子节点执行
new RandomSelector(childNode1, childNode2, childNode3);
new Sequence(
checkAmmo, // 检查弹药
aim, // 瞄准
shoot // 射击
)
// 只有全部成功才返回SUCCESS
```
2. 动作节点
#### Selector - 选择节点
选择第一个成功的子节点:
```typescript
// 行动节点 - 返回指定状态
new Action(() => {
console.log("执行动作");
return Status.SUCCESS; // 或 Status.FAILURE, Status.RUNNING
});
// 条件节点 - 检查条件返回成功或失败
new Condition((subject) => {
return subject.health > 50; // 返回 true 表示成功false 表示失败
});
// 等待节点
new WaitTime(2); // 等待2秒
new WaitTicks(5); // 等待5个tick
new Selector(
tryMeleeAttack, // 尝试近战
tryRangedAttack, // 尝试远程
retreat // 撤退
)
// 任一成功就返回SUCCESS
```
3. 装饰节点
#### Parallel - 并行节点
同时执行所有子节点,全部成功才成功:
```typescript
// 反转节点 - 反转子节点的成功/失败状态
new Inverter(childNode);
// 重复节点 - 重复执行子节点指定次数
new Repeat(childNode, 3);
// 重复直到失败 - 重复执行直到子节点失败
new RepeatUntilFailure(childNode, 5);
// 重复直到成功 - 重复执行直到子节点成功
new RepeatUntilSuccess(childNode, 5);
// 时间限制节点 - 限制子节点执行时间
new LimitTime(childNode, 5); // 5秒
// 次数限制节点 - 限制子节点执行次数
new LimitTimes(childNode, 3);
new Parallel(
moveToTarget, // 移动到目标
playAnimation, // 播放动画
updateUI // 更新UI
)
// 任一失败返回FAILURE有RUNNING返回RUNNING全部SUCCESS才返回SUCCESS
```
4. 使用黑板共享数据
#### ParallelAnySuccess - 并行任一成功
同时执行所有子节点,任一成功就成功:
```typescript
new ParallelAnySuccess(
findCover, // 寻找掩体
callForHelp, // 呼叫支援
counterAttack // 反击
)
// 任一SUCCESS就返回SUCCESS
```
#### Memory节点 - 状态记忆
记忆节点会记住上次执行位置,避免重复执行:
```typescript
// MemSequence - 记忆顺序节点
new MemSequence(
longTask1, // 第一次SUCCESS继续下一个
longTask2, // 第一次RUNNING记住这个位置 第二次从longTask2开始继续执行
longTask3
)
// MemSelector - 记忆选择节点
new MemSelector(
expensiveCheck1, // 第一次FAILURE继续下一个
expensiveCheck2, // 第一次RUNNING记住这个位置 第二次从expensiveCheck2开始执行
fallback // 如果前面都是FAILURE才会执行到这里
)
```
#### RandomSelector - 随机选择
随机选择一个子节点执行:
```typescript
new RandomSelector(
idleBehavior1,
idleBehavior2,
idleBehavior3
)
```
### 装饰节点 (Decorator)
#### Inverter - 反转节点
反转子节点的成功/失败状态:
```typescript
new Inverter(
new Condition((node) => {
const enemy = node.getEntity<Enemy>();
return enemy.isAlive;
})
) // 敌人死亡时返回SUCCESS
```
#### Repeat - 重复节点
重复执行子节点指定次数:
```typescript
new Repeat(
new Action((node) => {
console.log("射击");
return Status.SUCCESS;
}),
3 // 射击3次
)
```
#### RepeatUntilSuccess - 重复直到成功
```typescript
new RepeatUntilSuccess(
new Action((node) => {
console.log("尝试开门");
return Math.random() > 0.5 ? Status.SUCCESS : Status.FAILURE;
}),
5 // 最多尝试5次
)
```
#### RepeatUntilFailure - 重复直到失败
```typescript
new RepeatUntilFailure(
new Action((node) => {
console.log("收集资源");
return Status.SUCCESS; // 持续收集直到失败
}),
10 // 最多收集10次
)
```
#### LimitTime - 时间限制
```typescript
new LimitTime(
new Action((node) => {
console.log("执行复杂计算");
return Status.SUCCESS;
}),
2.0 // 最多执行2秒
)
```
#### LimitTicks - 次数限制
```typescript
new LimitTicks(
new Action((node) => {
console.log("尝试操作");
return Status.SUCCESS;
}),
5 // 最多执行5次
)
```
### 叶子节点 (Leaf)
#### Action - 动作节点
执行自定义逻辑:
```typescript
new Action((node) => {
// 直接获取实体
const target = node.getEntity<Character>();
// 访问黑板数据
const ammo = node.get<number>('ammo');
if (target && ammo > 0) {
console.log("攻击目标");
node.set('ammo', ammo - 1);
return Status.SUCCESS;
}
return Status.FAILURE;
})
```
#### Condition - 条件节点
检查条件:
```typescript
new Condition((node) => {
const player = node.getEntity<Player>();
const health = player.health;
return health > 50; // true->SUCCESS, false->FAILURE
})
```
#### WaitTime - 时间等待
```typescript
new WaitTime(2.5) // 等待2.5秒
```
#### WaitTicks - 帧数等待
```typescript
new WaitTicks(60) // 等待60帧
```
## 黑板系统
黑板系统提供分层数据存储,支持数据隔离和查找链:
```typescript
// 在节点中使用黑板
class CustomAction extends BaseNode {
tick<T>(tree: BehaviorTree<T>): Status {
// 获取数据 - 使用节点实例作为命名空间
const data = tree.blackboard.get<string>("key", this);
new Action((node) => {
// 直接获取实体
const entity = node.getEntity<Character>();
// 设置数据 - 使用节点实例作为命名空间
tree.blackboard.set("key", "value", this);
// 本地数据(仅当前节点可见)
node.set('local_count', 1);
const count = node.get<number>('local_count');
// 树级数据(整棵树可见)
node.setRoot('tree_data', 'shared');
const shared = node.getRoot<string>('tree_data');
// 全局数据(所有树可见)
node.setGlobal('global_config', config);
const config = node.getGlobal<Config>('global_config');
return Status.SUCCESS;
})
```
### 数据查找链
黑板数据按以下顺序查找:
1. 当前节点的本地黑板
2. 父节点的黑板
3. 递归向上查找到根节点
### Memory节点的数据隔离
Memory节点会创建独立的子黑板确保状态隔离
```typescript
const mem1 = new MemSequence(/* ... */);
const mem2 = new MemSequence(/* ... */);
// mem1 和 mem2 的记忆状态完全独立
```
## 完整示例
```typescript
import {
BehaviorTree, Status, Action, Condition,
Sequence, Selector, MemSelector, Parallel,
Inverter, RepeatUntilSuccess, LimitTime
} from 'kunpocc-behaviortree';
interface Character {
health: number;
mana: number;
hasWeapon: boolean;
isInCombat: boolean;
position: { x: number, y: number };
}
const character: Character = {
health: 80,
mana: 50,
hasWeapon: true,
isInCombat: false,
position: { x: 0, y: 0 }
};
// 构建复杂行为树
const behaviorTree = new BehaviorTree(character,
new Selector(
// 战斗行为
new Sequence(
new Condition((node) => {
const char = node.getEntity<Character>();
return char.isInCombat;
}),
new Selector(
// 生命值低时治疗
new Sequence(
new Condition((node) => {
const char = node.getEntity<Character>();
return char.health < 30;
}),
new RepeatUntilSuccess(
new Action((node) => {
const char = node.getEntity<Character>();
if (char.mana >= 10) {
char.health += 20;
char.mana -= 10;
console.log("治疗完成");
return Status.SUCCESS;
}
return Status.FAILURE;
}),
3 // 最多尝试3次
)
),
// 正常攻击
new Sequence(
new Condition((node) => {
const char = node.getEntity<Character>();
return char.hasWeapon;
}),
new LimitTime(
new Action((node) => {
console.log("发起攻击");
return Status.SUCCESS;
}),
1.0 // 攻击最多1秒
)
)
)
),
// 非战斗行为 - 巡逻
new MemSelector(
new Action((node) => {
console.log("巡逻点A");
return Status.SUCCESS;
}),
new Action((node) => {
console.log("巡逻点B");
return Status.SUCCESS;
}),
new Action((node) => {
console.log("巡逻点C");
return Status.SUCCESS;
})
)
)
);
// 执行行为树
console.log("=== 执行行为树 ===");
behaviorTree.tick(); // 输出: "巡逻点A"
// 进入战斗状态
character.isInCombat = true;
character.health = 20; // 低血量
behaviorTree.tick(); // 输出: "治疗完成"
```
## 最佳实践
### 1. 节点设计原则
- **单一职责**: 每个节点只做一件事
- **状态明确**: 明确定义SUCCESS/FAILURE/RUNNING的含义
- **避免副作用**: 尽量避免节点间的隐式依赖
### 2. 性能优化
```typescript
// ✅ 好的做法 - 使用记忆节点避免重复计算
new MemSelector(
expensivePathfinding, // 复杂寻路只计算一次
fallbackBehavior
)
// ❌ 避免 - 每次都重新计算
new Selector(
expensivePathfinding, // 每次tick都会重新计算
fallbackBehavior
)
```
### 3. 黑板使用
```typescript
// ✅ 好的做法 - 合理使用数据层级
new Action((node) => {
// 获取实体
const player = node.getEntity<Player>();
// 临时数据用本地黑板
node.set('temp_result', calculation());
// 共享数据用树级黑板
node.setRoot('current_target', target);
// 配置数据用全局黑板
node.setGlobal('game_config', config);
})
```
### 4. 错误处理
```typescript
// ✅ 明确的错误处理
new Action((node) => {
try {
const result = riskyOperation();
return result ? Status.SUCCESS : Status.FAILURE;
} catch (error) {
console.error('Operation failed:', error);
return Status.FAILURE;
}
})
```
## 测试覆盖
本库包含全面的测试用例,覆盖:
- ✅ 17种节点类型 (100%覆盖)
- ✅ Memory节点状态管理
- ✅ 黑板数据隔离
- ✅ 边界条件处理
- ✅ 复杂嵌套场景
运行测试:
```bash
npm test
```
## API 参考
### 核心类
#### `BehaviorTree<T>`
```typescript
constructor(entity: T, root: IBTNode)
tick(): Status // 执行一次行为树
reset(): void // 重置所有状态
```
#### `Status`
```typescript
enum Status {
SUCCESS = 0,
FAILURE = 1,
RUNNING = 2
}
```
### 节点接口
```typescript
interface IBTNode {
readonly children: IBTNode[];
// 节点黑板
local: IBlackboard;
tick(): Status;
#### 注意事项
// 优先写入自己的黑板数据, 如果没有则写入父节点的黑板数据
set<T>(key: string, value: T): void;
get<T>(key: string): T;
// 写入树根节点的黑板数据
setRoot<T>(key: string, value: T): void;
getRoot<T>(key: string): T;
// 写入全局黑板数据
setGlobal<T>(key: string, value: T): void;
getGlobal<T>(key: string): T;
1. 节点状态说明:
- `SUCCESS`:节点执行成功
- `FAILURE`:节点执行失败
- `RUNNING`:节点正在执行中
2. 组合节点特性:
- `Sequence`:所有子节点返回 SUCCESS 才返回 SUCCESS
- `Selector`:任一子节点返回 SUCCESS 就返回 SUCCESS
- `Parallel`:并行执行所有子节点
- `MemSequence/MemSelector`:会记住上次执行位置
3. 性能优化:
- 使用黑板共享数据,避免重复计算
- 合理使用记忆节点,减少重复执行
- 控制行为树的深度,避免过于复杂
// 实体访问
getEntity<T>(): T;
}
```
