这是我认为已回答的最后一个问题的后续，但由于某种原因，当我将舞台上的孩子（显示对象）视为影片剪辑时，我无法应用我想要的常用功能：

var mc1:MovieClip = this.getChildByName("mc1") as MovieClip;
if(mc1) {
    mc1.useHandCursor = true;
    mc1.buttonMode = true;
    mc1.addEventListener(MouseEvent.CLICK, fillDriveway);
}

任何智慧都将不胜感激......并且很抱歉提出与以前类似的问题......

提前致谢。

您确定影片剪辑是放在舞台上还是实际转换为影片剪辑？试试stage.getChildByName()。你把这段代码放在哪里了？在框架内还是在主文档类内？为了确保您可以检查孩子们是否已添加到舞台上，并查看他们的名字。您可以使用此代码

        for ( var i :int = 0; i < this.numChildren; i++ )
        {
            babe = this.getChildAt( i );
            if ( babe is MovieClip)  {
                trace( babe.name);
            }
        }

这个我也看到了，不知道好不好用。

if (stage.contains(mc1)) {

}

哇！弄清楚了！

通过弹出

var mc1:MovieClip = this.getChildByName("mc1") as MovieClip;

在我的 AS 结尾处，我指的是子“mc1”在它存在之前 - 在用户单击“pic”电影剪辑上的某个位置之前它不会被创建。所以解决方案是将我对“mc1”的操作（包括将其声明为 MovieClip）放入一个单独的函数中：

function createstartEndMC():void {
    var startEnd:MovieClip = (this.getChildByName("mc1")) as MovieClip;
    startEnd.useHandCursor = true;
    startEnd.buttonMode = true;
    startEnd.addEventListener(MouseEvent.CLICK, fillDriveway);
}

然后在创建“mc1”子项后调用此函数：

function addNewPoint(e:MouseEvent):void {
    n++;
    pointNo.text = String(n);
    if(n==1){
        var nextPoint:MovieClip = new mcstart();
        addChild(nextPoint);
        nextPoint.name = "mc"+pointNo.text;
        nextPoint.x = e.target.mouseX;
        nextPoint.y = e.target.mouseY;
        createstartEndMC();
    }

最后它工作了，“mc1”（或者我称之为“startEnd”，一旦它被创建并制作成一个 MC）最终表现得像一个正常的时间线 MC 应该的！

我很高兴-感谢您的所有指导！
