Question

我正在制作游戏，基本上是一个拖动游戏但是当我拖动我的对象时，此错误显示“TypeError：错误＃1034：类型强制失败：无法将flash.display :: Loader @ 25aa6d41转换为flash.display。影片剪辑“。我不知道如何调试它因为我是as3..please help

的新手

这是代码

它说你的代码中的某个地方，你想要使用一个MovieClip对象所在的Loader对象。浏览代码，我看到两个地方你已经将一个对象用作Movieclip（Loader无法工作）。尝试在这些位置搜索event.target以查看它是MovieClip对象还是您在其中的Loader对象。

如果显示加载器对象，则可能是导致错误的原因。尝试将event.target更改为event.currentTarget。

我理解差异的方式是event.target通常是您单击的对象（MovieClip对象中的Loader对象），而event.currentTarget是处理具有该事件的事件的对象listener，这是你在这种情况下追求的MovieClip。（任何人，如果我错了，请随时纠正我）

作为旁注，如果你正在使用Flash IDE，你也可以按'control + shift + enter'（而不仅仅是控制+输入）来使用调试器进行测试，这通常可以显示你的确切也给出错误的那一行。
