。cpp要声明的

 

 

#include "cocos2d.h"

#include "cocos-ext.h"



using namespace cocos2d;

using namespace extension;



class HelloWorld : public cocos2d::CCLayer

{

public:

    // Method 'init' in cocos2d-x returns bool, instead of 'id' in cocos2d-iphone (an object pointer)

    virtual bool init();



    // there's no 'id' in cpp, so we recommend to return the class instance pointer

    static cocos2d::CCScene* scene();

    

    // a selector callback

    void menuCloseCallback(CCObject* pSender);



    // preprocessor macro for "static create()" constructor ( node() deprecated )

    CREATE_FUNC(HelloWorld);

    

//    按下按钮事件回调

    void touchDownAction(CCObject * sender , CCControlEvent * controlEvent);

//    按钮在其内部拾起事件回调

    void touchUpInsideAction(CCObject * sender , CCControlEvent * controlEvent);

//    按钮在其外部拾起事件回调

        void touchUpOutsideAction(CCObject * sender , CCControlEvent * controlEvent);
