cocos2dx C++為Sprite添加觸摸事件監聽器

1.首先頭文件定義事件處理的函數原型

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

2.實現原型

bool ShopItem::onTouchBegan(Touch* tTouch,Event* eEvent){
　if (sprite->getBoundingBox().containsPoint(tTouch->getLocation())){//判斷觸摸點是否在目標的范圍內

　　　　/**這里為事件內容**/
　　　　return true;
　}else
　　　　return false;
　}	
}

void ShopItem::onTouchMoved(Touch* tTouch,Event* eEvent){
	/**這里為事件內容**/
}

void ShopItem::onTouchEnded(Touch* tTouch,Event* eEvent){
	/**這里為事件內容**/
}

3.綁定事件

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);
