1、CCMoveBy：移动动作，继承自CCActionInterval
class CC_DLL CCMoveBy : public CCActionInterval{public:bool initWithDuration(float duration, const CCPoint& deltaPosition); //初始化序列virtual CCObject* copyWithZone(CCZone* pZone);virtual void startWithTarget(CCNode *pTarget);//开始目标virtual CCActionInterval* reverse(void);virtual void update(float time);//更新public:static CCMoveBy* create(float duration, const CCPoint& deltaPosition);protected:CCPoint m_positionDelta;CCPoint m_startPosition;CCPoint m_previousPosition;};2、CCActionInterval：动作间隔类，，继承自CCFiniteTimeActionclass CC_DLL CCActionInterval : public CCFiniteTimeAction{public:inline float getElapsed(void) { return m_elapsed; }//获取从动作开始到目前已逝去的秒bool initWithDuration(float d);//初始化动作virtual bool isDone(void);//判断动作是否运行完成virtual CCObject* copyWithZone(CCZone* pZone);virtual void step(float dt);virtual void startWithTarget(CCNode *pTarget);/** returns a reversed action */virtual CCActionInterval* reverse(void);public:static CCActionInterval* create(float d);public:void setAmplitudeRate(float amp); //设置和获得扩展float getAmplitudeRate(void);protected:float m_elapsed;bool m_bFirstTick;};3、CCFiniteTimeAction：有限时间动作，继承自CCActionclass CC_DLL CCFiniteTimeAction : public CCAction{public:CCFiniteTimeAction(): m_fDuration(0){}virtual ~CCFiniteTimeAction(){}inline float getDuration(void) { return m_fDuration; }//设置和获得持续时间inline void setDuration(float duration) { m_fDuration = duration; }virtual CCFiniteTimeAction* reverse(void);//返回一个倒退序列protected:float m_fDuration;};4、CCCallFunc：动作回调函数处理类，继承自CCActionInstantclass CC_DLL CCCallFunc : public CCActionInstant{public:CCCallFunc(): m_pSelectorTarget(NULL), m_nScriptHandler(0), m_pCallFunc(NULL){}virtual ~CCCallFunc();static CCCallFunc * create(CCObject* pSelectorTarget, SEL_CallFunc selector);//创建和初始化相关函数static CCCallFunc * create(int nHandler);virtual bool initWithTarget(CCObject* pSelectorTarget); virtual void execute();//执行virtual void update(float time);//更新CCObject * copyWithZone(CCZone *pZone); inline CCObject* getTargetCallback()//设置和获得回调对象{return m_pSelectorTarget;}inline void setTargetCallback(CCObject* pSel){if (pSel != m_pSelectorTarget){CC_SAFE_RETAIN(pSel);CC_SAFE_RELEASE(m_pSelectorTarget);m_pSelectorTarget = pSel;}}inline int getScriptHandler() { return m_nScriptHandler; };//得到脚本句柄protected:CCObject* m_pSelectorTarget;int m_nScriptHandler;union{SEL_CallFunc m_pCallFunc;SEL_CallFuncN m_pCallFuncN;SEL_CallFuncND m_pCallFuncND;SEL_CallFuncO m_pCallFuncO;};};5、CC_SAFE_RETAIN：这个宏有意思，搞个一次循环#define CC_SAFE_RETAIN(p)do { if(p) { (p)->retain(); } } while(0)6、CCActionInstant：立即动作类，继承自CCFiniteTimeAction，比较简陋class CC_DLL CCActionInstant : public CCFiniteTimeAction{public:CCActionInstant();virtual ~CCActionInstant(){}virtual CCObject* copyWithZone(CCZone *pZone);virtual bool isDone(void);virtual void step(float dt);virtual void update(float time);virtual CCFiniteTimeAction * reverse(void);};
人生最好的旅行，就是你在一个陌生的地方，
