错误#2025:ActionScript编程问题

Question

问题是每次我试图进入下一个场景backStory它不会带走孩子。我想这样做，当柜台转到4它会把它拿出来，放在一个新的场景中。有办法解决这个问题吗？我不明白如何切换场景

我正在创建一个游戏，我得到这个错误：

ArgumentError:错误#2025:提供的DisplayObject必须是调用者的子级。at flash。display:：DisplayObjectContainer/removeChild（）在Runner/onEnterFrame（）

Answer 1

下面的行是错误的。

startPage.endStartPage == false;

修复：

startPage.endStartPage = false;
