Actionscript 3 在as3中添加向自身添加更多movieclip的movieclip时出错

好吧，当舞台（这个职业）是一个将玩家和敌人的电影嘴唇拉进去的职业时，它就起作用了。然后我在舞台上加了这个，在playscreen上做了另一个。。。

我不知道它为什么不起作用，但有谁能告诉我为什么不起作用，不会出现错误…

您必须将可变playscreen设置为新的avoiderclass对象，如下所示：

package  
{
    import flash.display.*;

    public class documentclass extends MovieClip
    {
        public var playscreen:avoiderclass;

        public function documentclass() 
        {
            playscreen.addEventListener(playerEvent.DEAD, onplayerdeath);
            playscreen.x = 0;
            playscreen.y = 0;
            playscreen = new avoiderclass();
            addChild(playscreen);
        }
        public function onplayerdeath(PlayerEvent:playerEvent):void
        {
            var Gameover:gameover = new gameover();
            Gameover.x = 0;
            Gameover.y = 0;
            addChild(Gameover);

            playscreen = null;
        }
    }

}

在做之前

        playscreen = new avoiderclass();

请这边试试

        playscreen.addEventListener(playerEvent.DEAD, onplayerdeath);
        playscreen.x = 0;
        playscreen.y = 0;

在这个函数中，不要忘记从displaylist中删除playscreen

public class documentclass extends MovieClip {
    public var playscreen:avoiderclass;

    public function documentclass(){
        // construct the object first
        playscreen = new avoiderclass();
        // then manipulate it.
        playscreen.addEventListener(playerEvent.DEAD, onplayerdeath);
        playscreen.x = 0;
        playscreen.y = 0;
        addChild(playscreen);
    }

怎么了？你没有真正解释什么是错的。如果没有对不起作用的内容和avoiderclass代码的描述，我们真的帮不了你多少忙。我花了一分钟来理解你的帖子，但当我意识到你基本上是在说“在你放playscreen=new avoiderclass（）；line…ThanksOk之前不要设置x和y”。谢谢你，试着用一种更容易理解的语言。你很好。

    public function onplayerdeath(PlayerEvent:playerEvent):void {
        var Gameover:gameover = new gameover();
        Gameover.x = 0;
        Gameover.y = 0;
        addChild(Gameover);
        // first remove the playscreen from display list
        removeChild(playscreen);
        // then set it to null, now really unreachable and eligible for gc
        playscreen = null;
    }
  }
}
