Question

我在自定义属性中遇到FileIn（）问题。每次我第一次执行我的脚本时，我都会得到一个未定义的类或函数。另外，当我关闭3ds max并使用我的自定义属性重新打开场景时，我总是会收到错误。

我希望有人可以帮助我理解我在代码中做错了什么。我真的希望有一个解决方案，因为FileIn（）对我来说非常有用，可以重用和组织我的代码。在此先感谢您的帮助：）

这是我的代码：

Global newAttrib = attributes posAttribs
(
fn addFunction FolderName vArray=
(
/*
1)  Get the root position of the installed position of 3ds max
2)  Get in the script file and then in the FolderName of the function
3)  Add all the function inside the vArray in a FileIn Loop
*/
for i = 1 to vArray.count do
(
FolderPosition =  ((GetDir #maxroot)+"\scripts\\" +FolderName + "\\")
FileIn(FolderPosition + vArray[i])
)
)

函数UICaptionChange未在您的MaxScript文件中定义，所以我会在您引用的文件中猜测它？

我不是百分之百确定这一点，但我的猜测是因为maxscript在执行之前已经解析了“open”函数，它将在运行定义新函数的FileIn命令之前解析functino。换句话说，你找到的功能太晚了，无法找到它们。

我建议将addFunction调用仅移动到一般主体上的全局范围。找到在执行过程中自行编写的代码非常令人困惑。此外，每次创建/打开属性时，您将重新解析这些包含的文件，因此您每次都需要支付重新编译的费用。

只需移动代码以将文件包含到文件头部（在全局范围内），它将仅在评估脚本时执行，并且您应该没问题

对不起我迟到的回复我几天没回家。我想我做了你说的话。

我创建了一个startup.ms文件，它位于3ds max脚本文件夹中。在该文件中，我添加了我的addFunction，然后通过添加ally我的其他函数（分离的maxscript文件）来调用它。这就像添加一个功能库。现在从我所看到的，它似乎是诀窍。再次感谢你的帮助。我真的很认可它:)
