c++ - 如何删除 Sprite 并再次使用相同的 Sprite

Question

我是初学者，目前我正在使用 cocos2d-x2.2.3 在 x 代码中开发类似 2048 的游戏。在我的游戏中我必须碰撞两个 Sprite 。碰撞时，我必须删除两个 spites 并添加一个新的 Sprite 在同一位置。我正在使用以下代码:

if(_player1->boundingBox().intersectsRect(_player2->boundingBox()))
{
this->removeChild(_player1, true);//it is not removing properly
this->removeChild(_player2, true);
_player1 = new CCSprite();
_player1->initWithFile("2.png");
_player1->setPosition(ccp(position.x,position.y));
this->addChild(_player1);//I have to add same player again
}

提前致谢

Answer 1

if(_player1->boundingBox().intersectsRect(_player2->boundingBox()))
{

this->removeChild(_player2, true);

if(_player1)
{
this->removeChild(_player1, true);


_player1 = new CCSprite();
_player1->initWithFile("2.png");
_player1->setPosition(ccp(position.x,position.y));
this->addChild(_player1);
}

}
