我正在创造一个游戏，如果你击中一个僵尸僵尸死了，他的头被击回你击中的方向。这就像用僵尸头打棒球，头是球。我有两个动画片段，僵尸和僵尸头。一旦僵尸被击中，它将播放其垂死的动画并移除自身，同时僵尸头将被添加到垂死的僵尸的x和y坐标，并像玩棒球一样被吹回。我已经完成了针对最热门和僵尸死亡和重生的代码，但是我似乎无法定位并且在被击中时将头部添加到垂死的僵尸。我已经完成了僵尸头的功能，但我怎么能把它添加到僵尸。我以为它会是这样的，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);
}
我甚至尝试过这个。头部确实会生成但只是保持静止并且不会飞回来当僵尸移除自身时它会自动移除，我不会这样做。我已经告诉ZombieHead何时在自己的班级中删除自己
var zh = new ZombieHead();
addChild(zh);
这是我到目前为止所做的 播放器

答案 0 :(得分：0)
你需要跟踪头部跟随身体的x，y值，一个enterFrame函数会做： 例如：
addEventListner(event.ENTER_FRAME,follow head);
function (event.ENTER_FRAME){
myhead.x == mybody.x
myhead.y == mybody.y
}
基本上，每个帧或每个帧周期内，头部将遵循主体x，y值。
答案 1 :(得分：0)
你显然是将头部添加到僵尸，而不是持有者类，然后，当你移除僵尸时，你也移除它的头部，因为那个头是僵尸的孩子。请将其添加到该僵尸的父级：
parent.addChild(zh);
另外，为了移动这些头部，应该让父类知道头部到达。所以，当你添加一个头部，并且你有一个僵尸阵列时，制作一个头部阵列，当头部会产生时会填充它们，当你希望你的头部消失时，它会减少，并且当你显然会迭代它时已经和僵尸做过了。
