10.cocos2dx C++為Sprite添加觸摸事件監聽器

標籤：body   one   php   事件監聽器   pos   2dx   處理   post   hone   

1.首先標頭檔定義事件處理的函數原型

1 private:2     bool onTouchBegan(Touch* tTouch,Event* eEvent);//手指按下事件3     void onTouchMoved(Touch* tTouch,Event* eEvent);//手指移動事件4     void onTouchEnded(Touch* tTouch,Event* eEvent);//手指離開事件

2.實現原型

 1 bool ShopItem::onTouchBegan(Touch* tTouch,Event* eEvent){ 2 　if (sprite->getBoundingBox().containsPoint(tTouch->getLocation())){//判斷觸摸點是否在目標的範圍內 3   4 　　　　/**這裡為事件內容**/ 5 　　　　return true; 6 　}else 7 　　　　return false; 8 　}  9 }10  11 void ShopItem::onTouchMoved(Touch* tTouch,Event* eEvent){12     /**這裡為事件內容**/13 }14  15 void ShopItem::onTouchEnded(Touch* tTouch,Event* eEvent){16     /**這裡為事件內容**/17 }

3.綁定事件

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);
