refactor(action): 重构动作系统架构并添加新功能 

重构动作系统核心架构，主要变更包括：
1. 将动作系统拆分为多个模块化头文件
2. 新增动作管理器实现集中管理
3. 添加瞬时动作、间隔动作和特殊动作类
4. 实现完整的缓动动画系统
5. 优化节点动作接口与性能

新增功能：
1. 支持颜色和翻转动画
2. 添加回调动作和节点管理动作
3. 实现跟随和速度控制等特殊动作
4. 提供30+种缓动函数支持

BREAKING CHANGE: 动作系统API不兼容旧版本，需更新相关调用代码

```
---
## 核心概念
### 创建动作
所有动作都使用静态工厂方法 `create()` 创建：
```cpp
// 创建移动动作
auto move = MoveTo::create(2.0f, Vec2(100, 100));
// 创建缩放动作
auto scale = ScaleTo::create(1.0f, 2.0f);
// 创建旋转动作
auto rotate = RotateBy::create(3.0f, 360.0f);
```
### 运行动作
通过节点的 `runAction()` 方法运行动作：
```cpp
sprite->runAction(move);
```
### 动作完成回调
使用 `setCompletionCallback()` 设置动作完成时的回调：
```cpp
auto action = MoveTo::create(2.0f, Vec2(100, 100));
action->setCompletionCallback([]() {
E2D_LOG_INFO("动作完成！");
});
sprite->runAction(action);
```
---
## 基本动作
### 移动动作
```cpp
// MoveTo - 移动到指定位置
auto moveTo = MoveTo::create(2.0f, Vec2(100, 100));
// MoveBy - 相对移动
auto moveBy = MoveBy::create(2.0f, Vec2(50, 0)); // 向右移动 50 像素
```
### 跳跃动作
```cpp
// JumpTo - 跳跃到指定位置
auto jumpTo = JumpTo::create(2.0f, Vec2(100, 100), 50, 3); // 跳到 (100,100)，高度 50，跳 3 次
// JumpBy - 相对跳跃
auto jumpBy = JumpBy::create(2.0f, Vec2(100, 0), 50, 3); // 向右跳跃 100 像素
```
### 贝塞尔曲线动作
```cpp
BezierConfig bezier;
bezier.controlPoint1 = Vec2(100, 200);
bezier.controlPoint2 = Vec2(200, 100);
bezier.endPosition = Vec2(300, 150);
// BezierTo - 贝塞尔曲线移动到指定位置
auto bezierTo = BezierTo::create(3.0f, bezier);
// BezierBy - 相对贝塞尔曲线移动
auto bezierBy = BezierBy::create(3.0f, bezier);
```
### 缩放动作
```cpp
// ScaleTo - 缩放到指定比例
auto scaleTo = ScaleTo::create(1.0f, 2.0f); // 缩放到 2 倍
auto scaleToXY = ScaleTo::create(1.0f, 2.0f, 1.5f); // X 缩放 2 倍，Y 缩放 1.5 倍
// ScaleBy - 相对缩放
auto scaleBy = ScaleBy::create(1.0f, 0.5f); // 缩小一半
```
### 旋转动作
```cpp
// RotateTo - 旋转到指定角度
auto rotateTo = RotateTo::create(2.0f, 90.0f); // 旋转到 90 度
// RotateBy - 相对旋转
auto rotateBy = RotateBy::create(2.0f, 360.0f); // 旋转 360 度
```
### 淡入淡出动作
```cpp
// FadeIn - 淡入（透明度从 0 到 1）
auto fadeIn = FadeIn::create(1.0f);
// FadeOut - 淡出（透明度从 1 到 0）
auto fadeOut = FadeOut::create(1.0f);
// FadeTo - 淡入到指定透明度
auto fadeTo = FadeTo::create(1.0f, 0.5f); // 淡入到 50% 透明度
```
### 闪烁动作
```cpp
// Blink - 闪烁
auto blink = Blink::create(2.0f, 5); // 2 秒内闪烁 5 次
```
### 色调动作
```cpp
// TintTo - 变化到指定颜色
auto tintTo = TintTo::create(1.0f, 255, 0, 0); // 变为红色
// TintBy - 相对颜色变化
auto tintBy = TintBy::create(1.0f, 50, 0, 0); // 红色通道增加 50
```
---
## 组合动作
### Sequence - 序列动作
按顺序依次执行多个动作：
```cpp
auto sequence = Sequence::create(
MoveTo::create(1.0f, Vec2(100, 100)),
DelayTime::create(0.5f),
FadeOut::create(1.0f),
CallFunc::create([]() { E2D_LOG_INFO("完成"); }),
nullptr // 必须以 nullptr 结尾
);
sprite->runAction(sequence);
```
### Spawn - 并行动作
同时执行多个动作：
```cpp
auto spawn = Spawn::create(
MoveTo::create(2.0f, Vec2(200, 200)),
RotateBy::create(2.0f, 360),
FadeIn::create(2.0f),
nullptr
);
sprite->runAction(spawn);
```
### Repeat - 重复动作
```cpp
// Repeat - 重复指定次数
auto repeat = Repeat::create(
Sequence::create(
MoveBy::create(0.5f, Vec2(50, 0)),
MoveBy::create(0.5f, Vec2(-50, 0)),
nullptr
),
5 // 重复 5 次
);
// RepeatForever - 永久重复
auto repeatForever = RepeatForever::create(
RotateBy::create(1.0f, 360)
);
sprite->runAction(repeatForever);
```
### DelayTime - 延时动作
```cpp
auto sequence = Sequence::create(
MoveTo::create(1.0f, Vec2(100, 0)),
DelayTime::create(1.0f), // 延时 1 秒
MoveTo::create(1.0f, Vec2(200, 0)),
nullptr
);
```
### ReverseTime - 反向动作
```cpp
auto move = MoveBy::create(1.0f, Vec2(100, 0));
auto reverse = ReverseTime::create(move->clone());
// 反向执行，相当于 MoveBy(1.0f, Vec2(-100, 0))
```
---
## 缓动动作
缓动动作使用装饰器模式包装其他动作，实现各种缓动效果。
### 使用缓动
```cpp
// 创建基础动作
auto move = MoveTo::create(3.0f, Vec2(500, 300));
// 用缓动包装
auto easeMove = EaseElasticOut::create(move);
sprite->runAction(easeMove);
```
### 可用缓动类型
| 缓动类 | 效果 |
|--------|------|
| `EaseQuadIn/Out/InOut` | 二次缓动 |
| `EaseCubicIn/Out/InOut` | 三次缓动 |
| `EaseQuartIn/Out/InOut` | 四次缓动 |
| `EaseQuintIn/Out/InOut` | 五次缓动 |
| `EaseSineIn/Out/InOut` | 正弦缓动 |
| `EaseExponentialIn/Out/InOut` | 指数缓动 |
| `EaseCircleIn/Out/InOut` | 圆形缓动 |
| `EaseBackIn/Out/InOut` | 回震缓动 |
| `EaseElasticIn/Out/InOut` | 弹性缓动 |
| `EaseBounceIn/Out/InOut` | 弹跳缓动 |
### 缓动效果说明
- **In**: 开始时慢，逐渐加速
- **Out**: 开始时快，逐渐减速
- **InOut**: 开始和结束时慢，中间快
### 示例
```cpp
// 弹性缓动
auto jump = JumpBy::create(2.0f, Vec2(200, 0), 100, 1);
auto elasticJump = EaseElasticOut::create(jump, 0.5f);
sprite->runAction(elasticJump);
// 弹跳缓动
auto scale = ScaleTo::create(1.0f, 2.0f);
auto bounceScale = EaseBounceOut::create(scale);
sprite->runAction(bounceScale);
// 指数缓动
auto move = MoveTo::create(2.0f, Vec2(300, 200));
auto expoMove = EaseExponentialInOut::create(move);
sprite->runAction(expoMove);
```
### 自定义缓动
```cpp
// 使用自定义缓动函数
auto customEase = EaseCustom::create(move, [](float t) {
// 自定义缓动函数
return t * t * (3.0f - 2.0f * t); // smoothstep
});
```
---
## 特殊动作
### Speed - 速度控制
动态控制动作的播放速度：
```cpp
auto move = MoveTo::create(5.0f, Vec2(500, 300));
auto speed = Speed::create(move, 0.5f); // 半速播放
sprite->runAction(speed);
// 运行时调整速度
speed->setSpeed(2.0f); // 2 倍速
```
### Follow - 跟随动作
使节点跟随另一个节点移动（常用于相机）：
```cpp
// 无边界跟随
auto follow = Follow::create(player);
// 带边界跟随
Rect boundary(0, 0, 2000, 2000); // 世界边界
auto followWithBoundary = Follow::create(player, boundary);
camera->runAction(follow);
```
### TargetedAction - 目标动作
在一个节点上运行动作，但作用于另一个节点：
```cpp
// 在 spriteA 上运行，但影响 spriteB
auto targeted = TargetedAction::create(spriteB, MoveTo::create(2.0f, Vec2(100, 100)));
spriteA->runAction(targeted);
```
---
## 瞬时动作
瞬时动作立即完成，没有动画过程。
### CallFunc - 回调动作
```cpp
// 无参数回调
auto callFunc = CallFunc::create([]() {
E2D_LOG_INFO("回调执行");
});
// 带节点参数的回调
auto callFuncN = CallFuncN::create([](Node* node) {
E2D_LOG_INFO("节点: %p", node);
});
```
### Place - 放置动作
```cpp
// 立即放置到指定位置
auto place = Place::create(Vec2(100, 100));
```
### FlipX/FlipY - 翻转动作
```cpp
auto flipX = FlipX::create(true); // 水平翻转
auto flipY = FlipY::create(true); // 垂直翻转
```
### Show/Hide - 显示/隐藏动作
```cpp
auto show = Show::create(); // 显示
auto hide = Hide::create(); // 隐藏
auto toggle = ToggleVisibility::create(); // 切换可见性
```
### RemoveSelf - 移除自身
```cpp
// 从父节点移除
auto removeSelf = RemoveSelf::create();
```
---
## 动作管理
### 停止动作
```cpp
// 停止所有动作
sprite->stopAllActions();
// 停止指定动作
sprite->stopAction(action);
// 根据标签停止动作
sprite->stopActionByTag(1);
// 根据标志位停止动作
sprite->stopActionsByFlags(0x01);
```
### 查询动作
```cpp
// 获取动作数量
size_t count = sprite->getActionCount();
// 检查是否有动作在运行
bool running = sprite->isRunningActions();
// 根据标签获取动作
Action* action = sprite->getActionByTag(1);
```
### 动作标签和标志位
```cpp
auto action = MoveTo::create(2.0f, Vec2(100, 100));
action->setTag(1); // 设置标签
action->setFlags(0x01); // 设置标志位
sprite->runAction(action);
```
---
## 完整示例
### 示例 1：角色移动动画
```cpp
void Player::moveTo(const Vec2& target) {
// 停止当前移动
stopActionByTag(TAG_MOVE);
// 创建移动动作
auto move = MoveTo::create(1.0f, target);
move->setTag(TAG_MOVE);
// 添加缓动效果
auto easeMove = EaseQuadInOut::create(move);
runAction(easeMove);
}
```
### 示例 2：UI 弹出动画
```cpp
void UIPanel::show() {
// 初始状态
setScale(0.0f);
setOpacity(0.0f);
setVisible(true);
// 并行动画：缩放 + 淡入
auto spawn = Spawn::create(
EaseBackOut::create(ScaleTo::create(0.3f, 1.0f)),
FadeIn::create(0.3f),
nullptr
);
runAction(spawn);
}
```
### 示例 3：游戏结束动画
```cpp
void GameOverLayer::playAnimation() {
// 从屏幕底部滑入
setPosition(Vec2(screenWidth / 2, screenHeight));
auto moveUp = MoveBy::create(1.0f, Vec2(0, -screenHeight));
moveUp->setCompletionCallback([this]() {
// 动画完成后启用按钮
restartBtn_->setEnabled(true);
});
// 添加缓动效果
auto easeMove = EaseQuadOut::create(moveUp);
runAction(easeMove);
}
```
### 示例 4：复杂序列动画
```cpp
void Enemy::playDeathAnimation() {
auto sequence = Sequence::create(
// 闪烁
Blink::create(0.5f, 3),
// 放大
ScaleTo::create(0.2f, 1.5f),
// 淡出
FadeOut::create(0.3f),
// 移除自身
RemoveSelf::create(),
nullptr
);
runAction(sequence);
}
```
### 示例 5：循环动画
```cpp
void Coin::startFloating() {
// 上下浮动
auto floatUp = MoveBy::create(0.5f, Vec2(0, 10));
auto floatDown = floatUp->reverse();
auto floatSequence = Sequence::create(
EaseSineInOut::create(floatUp),
EaseSineInOut::create(floatDown),
nullptr
);
// 永久循环
auto floatForever = RepeatForever::create(floatSequence);
floatForever->setTag(TAG_FLOAT);
runAction(floatForever);
}
```
---
## 性能优化建议
1. **复用动作**：对于频繁使用的动作，可以 `clone()` 复用
2. **合理使用标签**：便于管理和停止特定动作
3. **避免过多并发动作**：大量节点同时运行动作会影响性能
4. **及时停止不需要的动作**：节点销毁前调用 `stopAllActions()`

# Extra2D 动作系统重构规格文档
## 一、概述
本文档描述了 Extra2D 动作系统的重构方案，参考 Cocos2d-x 的动作系统设计模式，实现一个更加完善、易用、功能丰富的动作系统。
## 二、现有系统分析
### 2.1 当前类层次结构
```
Action (基类)
├── IntervalAction (有限时间动作基类)
│ ├── MoveBy/MoveTo
│ ├── ScaleBy/ScaleTo
│ ├── RotateBy/RotateTo
│ ├── FadeIn/FadeOut/FadeTo
│ ├── Sequence
│ ├── Spawn
│ ├── Delay
│ └── Loop
└── InstantAction (瞬时动作基类)
└── CallFunc
```
### 2.2 与 Cocos2d-x 的差异
| 特性 | Extra2D 当前 | Cocos2d-x | 差异说明 |
|------|-------------|-----------|---------|
| 类层次 | Action -> IntervalAction/InstantAction | Action -> FiniteTimeAction -> ActionInterval/ActionInstant | 缺少 FiniteTimeAction 中间层 |
| 动作管理 | Node 内部管理 | ActionManager 单例集中管理 | 缺少集中式管理 |
| 缓动动作 | EaseAction 静态方法 | ActionEase 类系（装饰器模式） | 不够灵活，无法组合 |
| 速度控制 | Action::speed_ 成员 | Speed 动作包装器 | 缺少动态速度控制 |
| 跟随动作 | 无 | Follow 类 | 缺失 |
| 跳跃动作 | 无 | JumpBy/JumpTo | 缺失 |
| 贝塞尔动作 | 无 | BezierBy/BezierTo | 缺失 |
| 闪烁动作 | 无 | Blink | 缺失 |
| 色调动作 | 无 | TintBy/TintTo | 缺失 |
| 重复动作 | Loop | Repeat/RepeatForever | 命名和功能差异 |
| 反向动作 | reverse() 方法 | reverse() 方法 | 相同 |
| 克隆动作 | clone() 方法 | clone() 方法 | 相同 |
## 三、重构目标
### 3.1 核心目标
1. **完善类层次结构** - 添加 FiniteTimeAction 中间层
2. **集中式动作管理** - 实现 ActionManager 单例
3. **装饰器模式缓动** - 实现 ActionEase 类系
4. **丰富动作类型** - 添加跳跃、贝塞尔、闪烁、色调等动作
5. **统一API风格** - 与 Cocos2d-x API 保持一致
### 3.2 设计原则
1. **组合优于继承** - 使用装饰器模式实现缓动和速度控制
2. **单一职责** - ActionManager 只负责动作调度
3. **开放封闭** - 易于扩展新动作类型
4. **接口隔离** - 不同类型动作提供不同接口
## 四、新类层次结构

public:
virtual ~Action() = default;
// 核心接口
virtual bool isDone() const;
virtual void startWithTarget(Node* target);
virtual void stop();
virtual void step(float dt);

float getAmplitudeRate() const { return amplitudeRate_; }
protected:
float elapsed_ = 0.0f;

public:
bool isDone() const override { return true; }
void step(float dt) override;
protected:
bool done_ = false;
};
```
### 5.5 ActionManager 动作管理器
```cpp
class ActionManager {
public:
static ActionManager* getInstance();
// 动作管理
void addAction(Action* action, Node* target, bool paused = false);
void removeAction(Action* action);

void removeAllActionsFromTarget(Node* target);
void removeAllActions();
// 查询
Action* getActionByTag(int tag, Node* target);
size_t getActionCount(Node* target) const;
// 暂停/恢复
void pauseTarget(Node* target);
void resumeTarget(Node* target);
bool isPaused(Node* target) const;

void update(float dt);
private:
struct ActionElement {
std::vector<Action*> actions;

ActionInterval* getInnerAction() const { return innerAction_; }
void startWithTarget(Node* target) override;
void stop() override;
void update(float time) override;
Action* reverse() const override;
Action* clone() const override;
protected:
ActionInterval* innerAction_ = nullptr;
};
```
### 5.7 Speed 速度控制动作

};
```
## 六、新增动作类型
### 6.1 JumpBy/JumpTo 跳跃动作
```cpp
class JumpBy : public ActionInterval {
public:
static JumpBy* create(float duration, const Vec2& position,
float height, int jumps);
protected:
Vec2 startPosition_;
Vec2 delta_;
float height_;
int jumps_;
};
class JumpTo : public JumpBy {
// 继承实现，目标位置版本
};
```
### 6.2 BezierBy/BezierTo 贝塞尔动作
```cpp
struct BezierConfig {
Vec2 controlPoint1;
Vec2 controlPoint2;
Vec2 endPosition;
};
class BezierBy : public ActionInterval {
public:
static BezierBy* create(float duration, const BezierConfig& config);
protected:
BezierConfig config_;
Vec2 startPosition_;
};
```
### 6.3 Blink 闪烁动作

public:
static Blink* create(float duration, int times);
protected:
int times_;
int currentTimes_;
bool originalVisible_;
};
```

};
```
### 6.6 瞬时动作扩展

// 放置到指定位置
class Place : public ActionInstant {
public:
static Place* create(const Vec2& position);
};
// X/Y轴翻转
class FlipX : public ActionInstant {
public:
static FlipX* create(bool flipX);
};

};
```
## 七、缓动动作完整实现
### 7.1 通用缓动包装器
```cpp
// 通用缓动包装器
class EaseCustom : public ActionEase {
public:
static EaseCustom* create(ActionInterval* action,
EaseFunction easeFunc);
};
// 指数缓动
class EaseExponentialIn : public ActionEase { /* ... */ };
class EaseExponentialOut : public ActionEase { /* ... */ };
class EaseExponentialInOut : public ActionEase { /* ... */ };
// 正弦缓动
class EaseSineIn : public ActionEase { /* ... */ };
class EaseSineOut : public ActionEase { /* ... */ };
class EaseSineInOut : public ActionEase { /* ... */ };
// 弹性缓动
class EaseElasticIn : public ActionEase {
public:
static EaseElasticIn* create(ActionInterval* action, float period = 0.3f);
};
class EaseElasticOut : public ActionEase { /* ... */ };
class EaseElasticInOut : public ActionEase { /* ... */ };
// 弹跳缓动
class EaseBounceIn : public ActionEase { /* ... */ };
class EaseBounceOut : public ActionEase { /* ... */ };
class EaseBounceInOut : public ActionEase { /* ... */ };
// 回震缓动
class EaseBackIn : public ActionEase { /* ... */ };
class EaseBackOut : public ActionEase { /* ... */ };
class EaseBackInOut : public ActionEase { /* ... */ };
// 贝塞尔缓动（自定义曲线）

public:
static EaseBezier* create(ActionInterval* action);
void setBezierParamer(float p0, float p1, float p2, float p3);
};
```
## 八、Node 类接口更新
### 8.1 动作相关接口
```cpp
class Node {
public:
// 运行动作
Action* runAction(Action* action);
// 停止动作
void stopAllActions();
void stopAction(Action* action);
void stopActionByTag(int tag);
void stopActionsByFlags(unsigned int flags);
// 获取动作
Action* getActionByTag(int tag);
size_t getNumberOfRunningActions() const;
// 暂停/恢复所有动作
void pauseAllActions();
void resumeAllActions();
// 检查是否有动作在运行
bool isRunningActions() const;
};
```
## 九、使用示例
### 9.1 基本动作
```cpp
// 移动
auto moveTo = MoveTo::create(2.0f, Vec2(100, 100));
sprite->runAction(moveTo);
// 跳跃
auto jump = JumpBy::create(2.0f, Vec2(200, 0), 100, 3);
sprite->runAction(jump);
// 贝塞尔曲线
BezierConfig bezier;
bezier.controlPoint1 = Vec2(100, 200);
bezier.controlPoint2 = Vec2(200, 100);
bezier.endPosition = Vec2(300, 150);
auto bezierAction = BezierTo::create(3.0f, bezier);
sprite->runAction(bezierAction);
```
### 9.2 组合动作
```cpp
// 序列动作
auto seq = Sequence::create(
MoveTo::create(1.0f, Vec2(100, 100)),
DelayTime::create(0.5f),
FadeOut::create(1.0f),
CallFunc::create([](){ log("Done!"); }),
nullptr
);
sprite->runAction(seq);
// 并行动作
auto spawn = Spawn::create(
MoveTo::create(2.0f, Vec2(200, 200)),
RotateBy::create(2.0f, 360),
FadeIn::create(2.0f),
nullptr
);
sprite->runAction(spawn);
// 重复动作
auto repeat = Repeat::create(MoveBy::create(1.0f, Vec2(50, 0)), 5);
sprite->runAction(repeat);
// 永久重复
auto repeatForever = RepeatForever::create(
Sequence::create(
MoveBy::create(1.0f, Vec2(100, 0)),
MoveBy::create(1.0f, Vec2(-100, 0)),
nullptr
)
);
sprite->runAction(repeatForever);
```
### 9.3 缓动动作
```cpp
// 使用缓动包装器
auto move = MoveTo::create(3.0f, Vec2(500, 300));
auto easeMove = EaseElasticOut::create(move, 0.5f);
sprite->runAction(easeMove);
// 指数缓动
auto jump = JumpBy::create(2.0f, Vec2(200, 0), 100, 1);
auto easeJump = EaseExponentialOut::create(jump);
sprite->runAction(easeJump);
// 弹跳缓动
auto scale = ScaleTo::create(1.0f, 2.0f);
auto bounceScale = EaseBounceOut::create(scale);
sprite->runAction(bounceScale);
```
### 9.4 速度控制
```cpp
// 慢动作回放
auto action = MoveTo::create(5.0f, Vec2(500, 300));
auto speed = Speed::create(action, 0.5f); // 半速
sprite->runAction(speed);
// 动态调整速度
speed->setSpeed(2.0f); // 2倍速
```
### 9.5 跟随动作
```cpp
// 相机跟随玩家
auto follow = Follow::create(player, Rect(0, 0, 2000, 2000));
camera->runAction(follow);
```

## 十二、兼容性考虑
### 12.1 API 变更
- 动作创建方式改为 `create()` 静态工厂方法
- `Loop` 重命名为 `Repeat`
- `Delay` 重命名为 `DelayTime`
- 动作管理由 `ActionManager` 集中处理
### 12.2 迁移指南
```cpp
// 旧写法
auto action = std::make_shared<MoveTo>(2.0f, Vec2(100, 100));
sprite->runAction(action);
// 新写法（推荐）
auto action = MoveTo::create(2.0f, Vec2(100, 100));
sprite->runAction(action);
// 旧写法（缓动）
auto action = EaseAction::create(MoveTo::create(2.0f, Vec2(100, 100)), easeInQuad);
// 新写法（缓动）
auto action = EaseQuadIn::create(MoveTo::create(2.0f, Vec2(100, 100)));
```
## 十三、性能优化
1. **对象池集成** - 动作对象使用对象池管理
2. **批量更新** - ActionManager 统一调度减少调用开销
3. **延迟删除** - 动作完成时标记删除，统一清理
4. **缓存友好** - 连续存储同一类型动作
## 十四、测试计划
1. 单元测试：每个动作类型的独立测试
2. 集成测试：组合动作测试
3. 性能测试：大量动作并发测试
4. 内存测试：动作对象生命周期测试
