10.cocos2dx C++为Sprite添加触摸事件监听器

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

1 bool ShopItem::onTouchBegan(Touch* tTouch,Event* eEvent){
2 　if (sprite->getBoundingBox().containsPoint(tTouch->getLocation())){//判断触摸点是否在目标的范围内
3
4 　　　　/**这里为事件内容**/
5 　　　　return true;
6 　}else
7 　　　　return false;
8 　}
9 }

11 void ShopItem::onTouchMoved(Touch* tTouch,Event* eEvent){
12     /**这里为事件内容**/
13 }

15 void ShopItem::onTouchEnded(Touch* tTouch,Event* eEvent){
16     /**这里为事件内容**/
17 }

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