在单击的菜单项上显示 window Python Maya

Question

我是 python 使用 Maya 编写脚本的新手我想自动加载我创建的插件以在 Maya 主 Window 中显示自定义菜单。单击菜单项时，它使用我创建的函数显示 window。所以问题是：当我运行我的代码只是在 Maya 界面中时，它运行是正确的但是当我把我的代码放在 python 文件中并自动加载它时，它每次都显示不同的错误：有时在打开 Maya 时第一次加载菜单项时单击它会显示此错误：

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

有时会显示此错误：

// Warning: file: C:/Program Files/Autodesk/MAYA20185/Maya2018/scripts/others/pluginWin.mel line 290: No initializePlugin() or initializePlugin2() function
 // 
// Error: file: C:/Program Files/Autodesk/MAYA20185/Maya2018/scripts/others/pluginWin.mel line 290:  (userInterface) //

这是我的代码：userInterface.py

import maya.cmds as cmds
import functools
import pymel.core as pm

def createUI(pWindowTitle):
    windowID = 'myWindowID'
    if cmds.window(windowID, exists=True):
        cmds.deleteUI(windowID)
    cmds.window(windowID, title=pWindowTitle, sizeable=False, resizeToFitChildren=True)
    cmds.rowColumnLayout(numberOfColumns=3, columnWidth=[(1,75), (2,60), (3,60) ], columnOffset=[(1,'right',3)])
    cmds.text(label='Time Range:')
    startTimeField = cmds.intField(value=cmds.playbackOptions(q=True, minTime=True))
    endTimeField = cmds.intField(value=cmds.playbackOptions(q=True, maxTime=True))
    cmds.text( label='Attribute:' )
    targetAttributeField = cmds.textField( text='rotateY' )
    cmds.separator( h=10, style='none' )
    cmds.separator( h=10, style='none' )
    cmds.separator( h=10, style='none' )
    cmds.separator( h=10, style='none' )
    cmds.separator( h=10, style='none' )
    def cancelCallback(*pArgs):
        if cmds.window(windowID, exists=True ):
            cmds.deleteUI(windowID)
    cmds.button(label='Cancel',command=cancelCallback)
    cmds.showWindow()

def keyFullRotation(pObjectName, pStartTime, pEndTime, pTargetAttribute):
    cmds.cutKey( pObjectName, time=(pStartTime, pEndTime), attribute=pTargetAttribute)
    cmds.setKeyframe( pObjectName, time=pStartTime, attribute=pTargetAttribute, value=0)
    cmds.setKeyframe( pObjectName, time=pEndTime, attribute=pTargetAttribute, value=360)    
    cmds.selectKey( pObjectName, time=(pStartTime, pEndTime), attribute=pTargetAttribute, keyframe=True)    
    cmds.keyTangent( inTangentType='linear', outTangentType='linear' )

MainMayaWindow = pm.language.melGlobals['gMainWindow'] 
customMenu = pm.menu('TestMenu', parent=MainMayaWindow)
pm.menuItem(label="menu item 'hihi'", command="createUI('My Title')", parent=customMenu)

首先千万不要把你的命令写成字符串，我想你有命名空间的问题。如果你真的想解析这样的变量，请尝试使用部分。如果你看我的帖子，我会给你一些建议。

所以试着改变你的台词:

def createUI():
    pWindowTitle = 'somethingFix'
    windowID = 'myWindowID'
    if cmds.window(windowID, exists=True):
        cmds.deleteUI(windowID)
    cmds.window(windowID, title=pWindowTitle, sizeable=False, resizeToFitChildren=True)



pm.menuItem(label="menu item 'hihi'", command=createUI, parent=customMenu)

在单击的菜单项上显示 window Python Maya

show window on menuItem clicked Python Maya

python
