添加简单的layer层的触摸事件。。单点触摸

在layer的初始化的init（）函数里面添加

//打开触摸开关
    setTouchEnabled(true);
    
    //2.2.1版本有修改http://www.cnblogs.com/TopWin/archive/2012/09/12/2682042.html
   CCDirector::sharedDirector()->getTouchDispatcher()->addTargetedDelegate(this, 0, true);

然后在layer的。h文件里面添加

    virtual bool ccTouchBegan(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent);
    virtual void ccTouchMoved(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent);
    virtual void ccTouchEnded(cocos2d::CCTouch *pTouch, CCEvent *pEvent);
    virtual void ccTouchCancelled(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent);

如果不想输入cocos2d：：CCTouch这样的形式，就必须在 include之后添加一句   USING_NS_CC;来使用cocos2d命名空间

然后在layer的cpp文件里面重写这四个函数

bool HelloWorld::ccTouchBegan(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent)
{
    bool bRet = true;
    
    CCLog("HelloWorld Touch Began");
    
    return bRet;
}

void HelloWorld::ccTouchMoved(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent)
{
    CCLog("HelloWorld Touch Moved");
}

void HelloWorld::ccTouchEnded(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent)
{
    CCLog("HelloWorld Touch Ended");
}

void HelloWorld::ccTouchCancelled(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent)
{
    CCLog("HelloWorld Touch Cancelled");
}
