自动图形用户界面，未在按钮上声明变量

Question

我还在学习如何编写我自己的GUI。柯达帮了我很大的忙，我一直在胡闹，一次学习一些小东西。然而，我遇到了一个错误，我似乎无法绕开。我正在使用的当前GUI是一个简单的工具，用于更改游戏中的bot设置。此gui应该有5个按钮设置困难，并有一个复选框的数目的机器人列表。

但是，当我选择一个困难级别，机器人号，并点击保存时，我得到了以下错误：

'Variable used without being declared'  

此错误发生在这一行(botSAVE按钮在末尾)：

FileWriteLine($file2, "aiSettings.setMaxNBots " & $botnum)    

我认为按钮函数'Func numClick()‘根据按下的按钮设置了这个变量，但显然我忽略了一些东西。希望这是一个简单的解决办法。有人看到是什么导致了这个错误吗？我已经在autoitcsript论坛上发布了这个问题，但是他们似乎回避了游戏自动化脚本，所以我并没有得到太多的帮助。

-If任何人都会看到我做错了什么，OR有一个指向主题的链接，该主题包括用按钮单击声明变量，帮助总是很受欢迎。我发现的唯一的话题是难以置信的模糊，或者与我所寻找的略有不同。

如果还想在函数之外使用变量值，则必须声明其作用域为全局的。因此，只需在多个函数声明之前添加一行Global $botnum (可能带有默认值).

显然，$skillset也是如此。

引发此错误是因为您使用了Opt("MustDeclareVars", 1)。但是，如果不将这些变量声明为全局变量，则无论如何都不能工作，因为该值是在函数中设置的，但在函数结束时再次丢弃。因此，当您在另一个函数中使用未初始化的它们时，始终会收到未初始化变量的默认值。
