您能否请您阅读收到的错误中的行号，然后更新您的问题以仅包含相关代码（即包含麻烦代码的函数）。 – Marty

'Shot'类是否扩展MovieClip/Sprite？ –

Shot扩展Sprite，并且错误位于第90行 – user3390593

只是一个猜测：你开始你的ENTER_FRAME循环，（这将删除 'B'）你说addChild(b)之前。尝试将“b”放在显示列表之前您尝试删除它！ 90

线是stage.removeChild(e.currentTarget);

有了这个，你需要转换e.currentTarget到DisplayObject：

stage.removeChild(e.currentTarget as DisplayObject);

我试过，但它只给了我另一个错误，第90行\t 1120：访问未定义的属性DisplayObject。 – user3390593

@ user3390593您需要'导入flash.display.DisplayObject'。 – Marty

编译！它只是不会拍摄Shot对象。它应该“射击”Shot对象，但它仍然不会 – user3390593

啊哈！我想我可能已经发现你的问题，但我不确定它是如何与错误代码相关的...

看看你的Shot班（我在这里找到了https://stackoverflow.com/questions/22244959/why-does-this-not-shoot）。每一帧，你都会告诉Shot类来测试它是否仍处于舞台的边界，如果是，则从舞台上移开。在第90行中，您还告诉舞台确定子弹是否仍在边界，如果是，则再次删除它。

您试图从舞台上删除两颗子弹！

同样，我强调，这似乎与错误代码无关，但希望它指向正确的方向。
