如何给sprite添加单击事件

Answer 1

1.首先头文件定义事件处理的函数原型private:boolonTouchBegan(Touch*tTouch,Event*eEvent);//手指按下事件voidonTouchMoved(Touch*tTouch,Event*eEvent);//手指移动事件voidonTouchEnded(Touch*tTouch,Event*eEvent);//手指离开事件2.实现原型boolShopItem::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**/　　　　returntrue;　}else　　　　returnfalse;　}}voidShopItem::onTouchMoved(Touch*tTouch,Event*eEvent){/**这里为事件内容**/}voidShopItem::onTouchEnded(Touch*tTouch,Event*eEvent){/**这里为事件内容**/}3.绑定事件autolistener=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);
