局部变量与全局变量，'name'EXAMPLE'未定义

Question

我正在创建一个自定义浮动窗口，我可以在其中拥有像架子一样的按钮，为我调用和运行脚本。对于像我这样不经常编写脚本的建模艺术家非常有用！ :P 我希望在不必过多修改 Script_B 的情况下解决这个问题，但我们会看看必须做什么！ :D

就目前而言，我有两个脚本，Script_A 和 Script_B。脚本 B 保存为“my_custom_script_name.py”。我正在尝试使用 Script_A 运行它，但变量从未正确定义。

当我运行 Script_A 并将 Script_B 保存在适当的位置时，UI 甚至无法加载，因为它在定义的第一个变量上出错。

# Error: NameError: file C:/Users/polyshifter/Documents/maya/2019/prefs/scripts\my_custom_script_name.py line 2: global name 'mc' is not defined # 

所以我们甚至还没有得到其他变量，它已经坏了。

脚本 A

import maya.cmds as mc
import maya.mel as mel

# Create a custom floating window with 
if mc.window('ToolsWindow', q=True, exists=True):
    mc.deleteUI('ToolsWindow')
if mc.workspaceControl('ToolsWorkspaceControl', q=True, exists=True):
    mc.deleteUI('ToolsWorkspaceControl')
mc.window('ToolsWindow')
mc.tabLayout('ToolsTabs')

###IMPORT PANEL###

tabMenu = mc.columnLayout("Menu", adj=True)
separator_long = mc.separator(
                         height=10,
                         style='in')


mc.button(label="MyCustomScript", command = "my_custom_script_com()")

mc.setParent('..')
mc.showWindow()

#### My custom script ####
def my_custom_script_com(*args):
    import my_custom_script_name
    my_custom_script_name.run_my_custom_script_ui()

脚本 B

def run_my_custom_script_ui():
    import maya.cmds as mc
    if mc.window('my_script_ui', q=True, exists=True):
        mc.deleteUI('my_script_ui')
    else:
        mc.window('my_script_ui')

    mc.columnLayout("Menu", adj=True)

    mc.button(label="Please_print", command = "please_print()")

    mc.setParent('..')
    mc.showWindow()
    def please_print():
        print "OMG IT'S FINALLY WORKING!! YAY!!"

我尝试将 Script_B 放在 Script_A 中，位于脚本的最后，例如：

def my_custom_script_com(*args):
    import maya.cmds as mc
    if mc.window('my_script_ui', q=True, exists=True):
        mc.deleteUI('my_script_ui')
    else:
        mc.window('my_script_ui')

    mc.columnLayout("Menu", adj=True)

    mc.button(label="Please_print", command = "please_print()")

    mc.setParent('..')
    mc.showWindow()
    def please_print():
        print "OMG IT'S FINALLY WORKING!! YAY!!"

在其中加载第一个 UI，然后是第二个，我看到了我的按钮，但是当我点击它时，我得到：

# Error: NameError: file <maya console> line 1: name 'please_print' is not defined #

如果有太多不需要的代码或任何我试图将其尽可能精简的内容，我深表歉意。这是我的第一个问题！

任何有助于使这些变量正常工作的帮助都会令人惊叹！

非常感谢大家的帮助！ Theodox 能够完美地解决这个问题！

但是....问题仍然存在于我的非简化脚本中！

我有这个艺术家莱昂纳多·莱齐 (Leonardo Lezzi) 的剧本。 "https://www.linkedin.com/pulse/super-bool-tool-python-leonardo-iezzi/" 当我使用他的脚本并尝试将其实施到我的脚本中时，它会导致错误。首先 pma 没有定义，然后他的定义都没有定义。

我尝试过制作他的 UI（教程一和主界面）并将它们定义为命令，但这对我来说也没有奏效。原因是因为（根据我今天学到的知识：D），在调用 Script_B（现在的布尔脚本）之后，maya 不再具有这些功能。

我发现唯一可行的方法是将布尔脚本放在我的主要脚本中，以便它与它一起使用。然后将他的 UI 定义为命令，然后在 ScriptA 中单击我的按钮列出这 2 个命令。然后运行它。但是然后返回并删除脚本中的定义并取消缩进，然后重新运行脚本。所以定义仍然是从以前运行定义的，但现在 ui 是在全局范围内创建的......显然，当你重新启动 Maya 时这会中断，我完全错过了如何定义它们的要点，同时仍然可以调用（是对吗？）当我点击按钮时。

这显然是一种黑客和愚蠢的做法，但我不明白如何让“超级布尔工具”从我的脚本中运行，只能通过采购 super_bool_tool.py

以下是我到目前为止的内容，但这里的想法再次是 不 在我的书架 ui 脚本中运行它。我想调用 python 脚本，这样它就可以独立运行了。

Answer 1

我已经更正了您脚本中的很多内容，请尝试查看。 您的脚本中发生了很多事情，我将在下面放置几个链接： How to use a slider value in calculations?

我可能没有在其他主题上说过的一件事是，如果您只是将其用作 maya.cmds，请不要使用 pymel Pymel 真的很酷，但它真的很慢。

此外，如果您将脚本分离为“superbool.py”，它应该可以通过以下方式工作：

import superbool
superbool.super_bool_ui()

最后尽量避免使用字符串来为命令或 ui 元素创建链接。尝试使用变量、字典、类！

Answer 2

如果我理解正确，那么您可以通过移动函数来获得第二种方法。比如：

def my_custom_script_com(*args):
    import maya.cmds as mc
    if mc.window('my_script_ui', q=True, exists=True):
        mc.deleteUI('my_script_ui')
    else:
        mc.window('my_script_ui')

    mc.columnLayout("Menu", adj=True)

    def please_print(): # define your function here
        print "OMG IT'S FINALLY WORKING!! YAY!!"

    mc.button(label="Please_print", command = "please_print()") # use the function

    mc.setParent('..')
    mc.showWindow()

这是因为必须先定义函数，然后才能调用它们。希望这有助于解决您的问题！我也从未使用过maya，但我知道在tkinter 中，命令将是tkinter.Button(label="Please_print", command=please_print)，而please_print 上没有引号。不确定这是否适用于这里！

如果您希望将please_print() 移动到全局空间，您可以将该部分嵌入到它自己的函数中（而不是非常非典型的函数的子函数）。它看起来像：

# make a global function
def please_print():
    print "OMG IT'S FINALLY WORKING!! YAY!!"

def my_custom_script_com(*args):
    import maya.cmds as mc
    if mc.window('my_script_ui', q=True, exists=True):
        mc.deleteUI('my_script_ui')
    else:
        mc.window('my_script_ui')

    mc.columnLayout("Menu", adj=True)

    mc.button(label="Please_print", command = "please_print()") # use the function

    mc.setParent('..')
    mc.showWindow()

或者也许最好的（使用 tkinter 表示法）是：

# make a global function
def please_print():
    print "OMG IT'S FINALLY WORKING!! YAY!!"

def my_custom_script_com(*args):
    import maya.cmds as mc
    if mc.window('my_script_ui', q=True, exists=True):
        mc.deleteUI('my_script_ui')
    else:
        mc.window('my_script_ui')

    mc.columnLayout("Menu", adj=True)

    mc.button(label="Please_print", command = please_print) # assign function without quotes or parenthesis

    mc.setParent('..')
    mc.showWindow()

Answer 3

这是玛雅人长期存在的问题。问题是您使用的是命令的字符串名称：

command = "please_print()"

但 'please_print' 在 run_my_custom_script_ui 内，并且在函数运行时超出范围。当您单击按钮时，没有可供 Maya 调用的“please_print”函数。

如果你颠倒顺序并传递函数对象本身，不带引号，你应该没问题（通过添加 按钮的功能，您确保它不会 超出范围并离开：

# this import does not need to be inside the function
import maya.cmds as mc

def run_my_custom_script_ui():

    # define this up here so it's in scope
    # when you want to call it below.  The *_
    # argument lets you ignore the default
    # argument which buttons always fire in Python

    def please_print(*_):
        print "OMG IT'S FINALLY WORKING!! YAY!!"

    if mc.window('my_script_ui', q=True, exists=True):
        mc.deleteUI('my_script_ui')
    else:
        mc.window('my_script_ui')

    mc.columnLayout("Menu", adj=True)

    mc.button(label="Please_print", command = please_print)

    mc.setParent('..')
    mc.showWindow()
