x结构学习（十五）CCJumpBy、CCRotateBy、CCSpawn、CCSpeed

1、CCJumpBy：跳跃，继承自CCActionInterval

class CC_DLL CCJumpBy : public CCActionInterval{public:bool initWithDuration(float duration, const CCPoint& position, float height, unsigned int jumps);virtual CCObject* copyWithZone(CCZone* pZone);virtual void startWithTarget(CCNode *pTarget);virtual void update(float time);virtual CCActionInterval* reverse(void);public:static CCJumpBy* create(float duration, const CCPoint& position, float height, unsigned int jumps);protected:CCPointm_startPosition;CCPointm_delta;floatm_height;unsigned int m_nJumps;CCPointm_previousPos;};2、CCRotateBy：旋转，继承自CCActionIntervalclass CC_DLL CCRotateBy : public CCActionInterval{public:static CCRotateBy* create(float fDuration, float fDeltaAngle);bool initWithDuration(float fDuration, float fDeltaAngle);static CCRotateBy* create(float fDuration, float fDeltaAngleX, float fDeltaAngleY);bool initWithDuration(float fDuration, float fDeltaAngleX, float fDeltaAngleY);virtual CCObject* copyWithZone(CCZone* pZone);virtual void startWithTarget(CCNode *pTarget);virtual void update(float time);virtual CCActionInterval* reverse(void);protected:float m_fAngleX;float m_fStartAngleX;float m_fAngleY;float m_fStartAngleY;};3、CCSpawn：继承自CCActionIntervalclass CC_DLL CCSpawn : public CCActionInterval{public:~CCSpawn(void);bool initWithTwoActions(CCFiniteTimeAction *pAction1, CCFiniteTimeAction *pAction2);virtual CCObject* copyWithZone(CCZone* pZone);virtual void startWithTarget(CCNode *pTarget);virtual void stop(void);virtual void update(float time);virtual CCActionInterval* reverse(void);public:static CCSpawn* create(CCFiniteTimeAction *pAction1, …);static CCSpawn* createWithVariableList(CCFiniteTimeAction *pAction1, va_list args);static CCSpawn* create(CCArray *arrayOfActions);static CCSpawn* createWithTwoActions(CCFiniteTimeAction *pAction1, CCFiniteTimeAction *pAction2);protected:CCFiniteTimeAction *m_pOne;CCFiniteTimeAction *m_pTwo;};4、CCSpeed：速度，，继承自CCAction

class CC_DLL CCSpeed : public CCAction{public:CCSpeed(): m_fSpeed(0.0), m_pInnerAction(NULL){}virtual ~CCSpeed(void);inline float getSpeed(void) { return m_fSpeed; }//设置和获得速度inline void setSpeed(float fSpeed) { m_fSpeed = fSpeed; }bool initWithAction(CCActionInterval *pAction, float fSpeed);virtual CCObject* copyWithZone(CCZone *pZone);virtual void startWithTarget(CCNode* pTarget);virtual void stop();virtual void step(float dt);virtual bool isDone(void);virtual CCActionInterval* reverse(void);void setInnerAction(CCActionInterval *pAction);inline CCActionInterval* getInnerAction(){return m_pInnerAction;}public:static CCSpeed* create(CCActionInterval* pAction, float fSpeed);protected:float m_fSpeed;CCActionInterval *m_pInnerAction;};
