flash - AS3:类型强制失败:无法转换 flash.display::MovieClip

Question

更新:

现在我收到此错误:

TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip

从这个类:

package com.George.MegaAmazingApp.Components
{
    import flash.display.MovieClip;
    import flash.display.Stage;
    import flash.events.MouseEvent;

    public class Wheel extends MovieClip
    {

        public function Wheel(area:MovieClip, diagram:MovieClip)
        {
            area.addEventListener(MouseEvent.CLICK, clickHandler);
        }
        private function clickHandler(event:MouseEvent):void
        {
            trace("wheel clicked");
            trace("this is diagram");
        }

    }

}

和这个脚本:

import com.George.MegaAmazingApp.Components.*;

var wheel:Wheel = new Wheel(this.wheel,this.car);

调试给出:

GeorgesMegaAmazingApp-app.xml 不存在于该目录中，但我不知道它为什么会在那里查找，它不是 fla 所在的位置。

要么this.wheel或 this.car不是 MovieClip .您还可以在"file">“发布设置”中打开调试吗？然后，您将获得更好的错误消息，因为如果没有更多信息，您的错误可能会出现在任何地方。

编辑:

尝试重命名 var wheel到别的东西，因为 Flash 似乎与你的两个轮子对象混淆了。例如，尝试:

var wheelObject:Wheel = new Wheel(this.wheel,this.car);
