如何创建Maya滑块以在界面中移动对象

Question

我正在尝试使用滑块沿x，y和z轴移动对象。这是到目前为止我的代码：

import maya.cmds as cmds 

cmds.columnLayout(adjustableColumn=True)             

cmds.intSlider(min=-100, max=100, value=0, step=1, dc = cmds.move(x=True)) 

cmds.showWindow() 

我不断收到此错误

# Error: line 1: TypeError: file <maya console> line 10: Invalid arguments for flag 'dc'. Expected string or function, got NoneType # 

我很新的Python的，所以我不知道这意味着什么。非常感谢，马丁

你必须创建一个包含函数cmds.move（）

import maya.cmds as cmds 
from functools import partial 

# Create the function to move 
def moveXYZ(slider, *args, **kwargs): 
    # slider is the name of the controller 
    # *args is to avoid a maya default argument passed trhought functions 
    # **kwargs is used to pass maya flags to the function in order to chose X, Y or Z axis 

    # the slider value is queried each time in order to refresh the value 
    value = getSliderValue(slider) 
    cmds.move(value, **kwargs) 

# slider get value, can fit any slider if you provide the name 
def getSliderValue(ctrlName): 
    value = cmds.intSlider(ctrlName, q=True, value=True) 
    return value 

#basic window 
cmds.window()  
cmds.columnLayout(adjustableColumn=True)             
# create the slider with a placeholder function 
mySlider = cmds.intSlider(min=-100, max=100, value=0, step=1, dc = 'empty') 
# now that the var mySlider is created, we can pass it as argument for our function 
# let's edit the function with functools.partial that allow us to pass some arguments to a function 
# Here we pass moveXYZ function then mySlider, the name of the X slider then x=1 to pass the flag to cmds.move(x=1) 
cmds.intSlider(mySlider, e=True, dc = partial(moveXYZ, mySlider, x=1)) 

#redo it for all sliders 
# mySlider should be a dictionnary or at least a global, i.e : 
# uiDic = {} 
# uiDic['xslider'] = cmds.intSlider(min=-100, max=100, value=0, step=1, dc = 'empty') 
# cmds.intSlider(uiDic['xslider'], e=True, dc = partial(moveXYZ, uiDic['xslider'], x=1)) 

cmds.showWindow() 

我可以解释任何一部分，你不会明白的
