Question

这是从我最后一个问题得出的结论，我认为这个问题得到了回答，但由于某些原因，当我将舞台的一个孩子（显示对象）视为一个动画片段时，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);
}

任何智慧都会非常感激...并且对于提出与之前类似的问题感到遗憾......

提前致谢。

Answer 1

您确定将动画片段放置在舞台上还是实际转换为动画片段？试试stage.getChildByName()。你把这个代码放在哪里了？在框架内或主文档类内？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);
            }
        }

我也看过这个，不确定它是否有效。

if (stage.contains(mc1)) {

}

Answer 2

嗬！想出来了！

弹出

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

在我的AS结束时我指的是孩子“mc1”才存在 - 直到用户点击“pic”动画片段的某个地方才会创建它。因此，解决方案是将我对“mc1”（包括将其声明为MovieClip）的操作添加到单独的函数中：

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();
    }

最后它的工作原理和“mc1”（或称为“startEnd”，因为我称它为创建并制成MC后）最终表现为MC应该正常的时间线！

我很高兴 - 感谢您的所有指导！
