cocos2dx为Sprite添加触摸事件监听器

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

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**/
}

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);
