我正在创建一个游戏，如果你击中一个僵尸，僵尸就会死亡，他的头会被送回你击中的方向。我有两个电影剪辑僵尸和僵尸头。一旦僵尸被击中，它会播放它的垂死动画并移除自己，同时僵尸头部将被添加到垂死的僵尸身上并被吹回来。我已经完成了 hittest 和僵尸死亡和重生的代码，但是当它被击中时，我似乎无法定位并将头部添加到垂死的僵尸。我怎样才能做到这一点。我以为会是这样，我在僵尸类的PlayDeathAnimation函数中添加了这个但是没有用：
for (var i=0; i < MovieClip(parent).zombies.length; ++i)
{
var zh = new ZombieHead();
zh.x = MovieClip(parent).zombies[i].x;
zh.y = MovieClip(parent).zombies[i].y;
zh.rotation = MovieClip(parent).zombies[i].rotation;
addChild(zh);
}
