1、CCMenuItemImage：图像菜单项类，继承自CCMenuItemSprite

class CC_DLL CCMenuItemImage : public CCMenuItemSprite{public:    CCMenuItemImage(){}    virtual ~CCMenuItemImage(){}    static CCMenuItemImage* create(const char *normalImage, const char *selectedImage);               //下面是四个创建方面的重载函数    static CCMenuItemImage* create(const char *normalImage, const char *selectedImage, const char *disabledImage);    static CCMenuItemImage* create(const char *normalImage, const char *selectedImage, CCObject* target, SEL_MenuHandler selector);    static CCMenuItemImage* create(const char *normalImage, const char *selectedImage, const char *disabledImage, CCObject* target, SEL_MenuHandler selector);        bool init();            //两个初始化函数    bool initWithNormalImage(const char *normalImage, const char *selectedImage, const char *disabledImage, CCObject* target, SEL_MenuHandler selector);    void setNormalSpriteFrame(CCSpriteFrame* frame);     //精灵帧相关函数    void setSelectedSpriteFrame(CCSpriteFrame* frame);    void setDisabledSpriteFrame(CCSpriteFrame* frame);    static CCMenuItemImage* create();};

2、CCMenuItemSprite：精灵菜单项类，继承自CCMenuItem

class CC_DLL CCMenuItemSprite : public CCMenuItem{    CC_PROPERTY(CCNode*, m_pNormalImage, NormalImage);          //建立3个属性，并设置获取和设置属性函数    CC_PROPERTY(CCNode*, m_pSelectedImage, SelectedImage);    CC_PROPERTY(CCNode*, m_pDisabledImage, DisabledImage);public:    CCMenuItemSprite()    :m_pNormalImage(NULL)    ,m_pSelectedImage(NULL)    ,m_pDisabledImage(NULL)    {}    static CCMenuItemSprite * create(CCNode* normalSprite, CCNode* selectedSprite, CCNode* disabledSprite = NULL); //3个创建函数    static CCMenuItemSprite * create(CCNode* normalSprite, CCNode* selectedSprite, CCObject* target, SEL_MenuHandler selector);    static CCMenuItemSprite * create(CCNode* normalSprite, CCNode* selectedSprite, CCNode* disabledSprite, CCObject* target, SEL_MenuHandler selector);    bool initWithNormalSprite(CCNode* normalSprite, CCNode* selectedSprite, CCNode* disabledSprite, CCObject* target, SEL_MenuHandler selector);//初始化函数        virtual void selected();                  //选中或取消    virtual void unselected();    virtual void setEnabled(bool bEnabled);              //设置是否可用protected:    virtual void updateImagesVisibility();               //更新图像可见性};

3、CCAction：动作执行类，继承自CCObject

class CC_DLL CCAction : public CCObject {public:    CCAction(void);    virtual ~CCAction(void);       const char* description();            //返回一个描述字符串        virtual CCObject* copyWithZone(CCZone *pZone);  //复制区域    virtual bool isDone(void);             //返回动作是否完成    virtual void startWithTarget(CCNode *pTarget);    //开始    virtual void stop(void);                        //停止    virtual void step(float dt);                    //根据事件间隔执行    virtual void update(float time);             //更新        inline CCNode* getTarget(void) { return m_pTarget; }                     //获得和设置目标    inline void setTarget(CCNode *pTarget) { m_pTarget = pTarget; }        inline CCNode* getOriginalTarget(void) { return m_pOriginalTarget; }        //设置和获得之前的目标    inline void setOriginalTarget(CCNode *pOriginalTarget) { m_pOriginalTarget = pOriginalTarget; }    inline int getTag(void) { return m_nTag; }                   //设置和获得标签    inline void setTag(int nTag) { m_nTag = nTag; }public:    static CCAction* create();protected:    CCNode    *m_pOriginalTarget;    CCNode    *m_pTarget;    int     m_nTag;};

4、两个宏：ccp和CCPointMake

#define ccp(__X__,__Y__) cocos2d::CCPointMake((float)(__X__), (float)(__Y__))

#define CCPointMake(x, y) CCPoint((float)(x), (float)(y))
