动态删除影片剪辑

Question

第一次海报，长时间阅读。 我一直在解决这个问题。我一直被困在我的游戏中4个小时，搜索并试图找出如何去做。 我有一个游戏，我添加一些卡通蚂蚁，当他们被点击时，他们需要从舞台上删除。有4种不同类型的蚂蚁，所以即时通过Math.random选择要添加哪一种。 （蚂蚁1 + 2 + 3具有50％的机会产卵和第四50％）

rnd_nbr = (Math.random() * 5)+1; 

我有一个计时器做10蜱，以及i重置计时器，使无休止。 然后，我有一个随机数学，如果句子添加麦克'从Tweener移动舞台，和点击事件监听器。 但我无法弄清楚如何删除他们点击。 我在click_candy_anty函数中做了很多失败的尝试。 我已将他们留下评论。

我对abit凌乱的编码表示歉意，但是它会在（希望）它能够正常工作时被清除。

帮助受到高度赞赏。

Answer 1

您还可以使用：

removeChild(evt.currentTarget as DisplayObject); 

或者

var clicked_ant:DisplayObject = evt.currentTarget as DisplayObject; 
removeChild(clicked_ant); 

Answer 2

假设你已经创建了一个蚂蚁类，你可以有这样的事情

private function init():void 
{ 
     this.addEventListener(MouseEvent.CLICK , clickHandler); 
} 

private function clickHandler(event:MouseEvent):void 
{ 
     this.removeEventListener(MouseEvent.CLICK , clickHandler); 

     if(this.parent != null) 
      this.parent.removeChild(this); 
}
