此行抛出堆栈错误（FlashDevelop）而不是编译错误。我还有其他错误，但我认为其他错误可能就是这样。
任何人都可以理解为什么它在代码的这个基本部分出现问题？
在外部错误查看器中显示时为1009。
行
if (stage) {init();}
抛出此错误。
它不会在没有错误的情况下附加第二个精灵 - 尽管它似乎确实设置在舞台上 - 即使它们之前也没有给出任何结果（4.4.2）但是我刚刚更新到4.4.3。

除了eventlistener相关函数之外，所有函数都是（）：void 找你自己没有未初始化的变量 - 一切都在使用前定义。 完全无法创建文本字段，这就是stage.focus失败的原因。
