Question

更新：

现在我收到了这个错误：

TypeError：错误＃1034：类型强制失败：无法转换flash.display :: MovieClip

从这堂课开始：

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在该目录中不存在，但我不知道为什么它正在寻找那里，它不是fla所在的位置。

Answer 1

this.wheel或this.car不是MovieClip。你也可以在File＆gt;中打开调试吗？发布设置？然后，您将获得更好的错误消息，因为如果没有更多信息，您的错误可能就在任何地方。

修改

尝试将var wheel重命名为其他内容，因为Flash似乎与您的两个轮对象混淆。例如，尝试：

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

Answer 2

Wheel.as是否在目录com / George / MegaAmazingApp / Components中？（区分大小写）这是源路径目录中的'com'目录吗？
