错误 #2025：ActionScript 编程问题

Question

问题是每次我尝试继续下一个场景的背景故事 它不会删除孩子。我想这样做，这样当柜台转到 4 将其取出并放入新场景。有没有办法解决这个问题？不明白怎么切换场景

我正在创建游戏，但出现此错误：

ArgumentError: 错误 #2025: 提供的 DisplayObject 必须是 来电者的孩子。 在 flash.display::DisplayObjectContainer/removeChild() 在 Runner/onEnterFrame()

下面一行是错误的。

startPage.endStartPage == false;

修复：

startPage.endStartPage = false;
