10.cocos2dx C++为Sprite添加触摸事件监听器

1.首先头文件定义事件处理的函数原型

 private:
     bool onTouchBegan(Touch* tTouch,Event* eEvent);//手指按下事件
     void onTouchMoved(Touch* tTouch,Event* eEvent);//手指移动事件
     void onTouchEnded(Touch* tTouch,Event* eEvent);//手指离开事件

2.实现原型

 bool ShopItem::onTouchBegan(Touch* tTouch,Event* eEvent){
 　if (sprite->getBoundingBox().containsPoint(tTouch->getLocation())){//判断触摸点是否在目标的范围内

 　　　　/**这里为事件内容**/
 　　　　return true;
 　}else
 　　　　return false;
 　}
 }

 void ShopItem::onTouchMoved(Touch* tTouch,Event* eEvent){
     /**这里为事件内容**/
 }

 void ShopItem::onTouchEnded(Touch* tTouch,Event* eEvent){
     /**这里为事件内容**/
 }

3.绑定事件

     auto listener = EventListenerTouchOneByOne::create();
     listener->onTouchBegan = CC_CALLBACK_2(ShopItem::onTouchBegan, this);
     listener->onTouchMoved = CC_CALLBACK_2(ShopItem::onTouchMoved, this);
     listener->onTouchEnded = CC_CALLBACK_2(ShopItem::onTouchEnded, this);
     this->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener, sprite);
