cocos2d-x 精灵监听点击事件

http://labs.easymobi.cn/?p=5167

实现过程，实现CCTouchDelegate接口，在enter 的时候添加监听，exit 和析构时移除监听，点击时将touch 的坐标转化为相对精灵的坐标，如果是否在精灵的范围内，则响应点击。主要是参考前面两篇文章中的例子，不同的地方在判断区域，个人觉得太复杂。所以稍微修改了下，看起来更容易理解。

PianoTile.h

classPianoTile:publiccocos2d::CCSprite,publiccocos2d::CCTouchDelegate{public:PianoTile();~PianoTile();//lifecyclevirtualvoidonEnter();virtualvoidonExit();//touchvirtualboolccTouchBegan(CCTouch*pTouch,CCEvent*pEvent);virtualvoidccTouchEnded(CCTouch*pTouch,CCEvent*pEvent);};
