我应该首先让您知道我正在尝试从 Maya 重新创建目标约束 UI。这是我第一次使用 python，所以我只是做了一个小项目来围绕它。

问题儿童是保持偏移布尔和世界向上向量枚举。我不知道如何调用他们的结果来驱动目标约束的变量。

行。所以我在让我的 if/else 语句正常工作时遇到了一些麻烦。每次我尝试使用它们（维护偏移行，世界向上类型行）时，我都会收到“无效的语法”或“意外的缩进”或其他一些我在使用 Csharp 时从未统一的错误。最重要的是，我无法弄清楚如何通过另一个定义来调用一个定义。

（为了方便查看，我删掉了很多不太重要的项目。）

新错误得到了很好的解释：

# Error: addCallBack() takes exactly 2 arguments (1 given) #

你定义了：

def addCallBack(applyConstraint, worldUpTypeDef):

所以你必须在这里使用 partial 来提供你的 def ：

第 131 行：cmds.button( label='Add', command=addCallBack )

[...etc]

cmds.button( label='Add', command=partial(addCallBack, "First Arg", "Scnd Arg") )

[...etc]

def addCallBack(applyConstraint, worldUpTypeDef, *args):

请注意，maya ui 除了您的命令标志之外还返回 True 值，这就是为什么我们将“*args”添加到 def

- - 编辑 - -

有关部分的更多解释：Maya Python - 使用 UI 中的数据

请注意，我写的是：“First Arg”，但它可以是任何类型的数据：字符串、列表、值、参数、字典、def、类...等
