Maya中的Python:main函数在传递变量时调用其他函数?

我是一个动画师谁是一个初学者在编码…我感谢你的帮助

我正在编写一个Python脚本来自动复制Maya中的控制器对象。它为角色手部的每个骨骼创建控制器

它作为一个长函数运行良好,但我希望有一个主函数“handCtrls()”,在其中为各种任务调用函数。我还需要将变量传递给子函数,因为我正在迭代变量“I”

我在调用函数“nullgropper(side,boney,I,ctrl)”的行上得到一个错误,该错误表示“全局变量‘ctrl’未定义”。但它是在“ctrlDup”函数中定义的,我使用了“return-ctrl”,我认为它会将该变量发送回“handCtrls()”

代码如下:

import maya.cmds as c

def ctrlDup(side, boney, i, ctrlOrig):
    #Select and duplicate the original Control, and place it at the appropiate boney
    c.select(ctrlOrig)
    ctrl = c.duplicate(ctrlOrig, n=side + boney + str(i) + '_CTRL')
    print(ctrl)
    print('ctrlDup passed')
    return ctrl

def nullGrouper(side, boney, i, ctrl):
    #Create null group at same position as Control
    print(ctrl)
    print(ctrl[0])
    nullGrp = c.group(n=side + boney + str(i) + '_GRP', empty=1, world=1)
    print(nullGrp)
    c.parentConstraint(ctrl, nullGrp, n='nullGrp_parentConstr_temp')
    c.delete('nullGrp_parentConstr_temp')
    print('nullGrouper passed')
    return ctrl, nullGrp
def handCtrls():
    #First select the Controller to be duplicated
    sel = c.ls(sl=1)
    ctrlOrig = sel[0]
    #List sides
    sideList = ['L_', 'R_']
    #List bones of part
    boneyList = ['thumb', 'index', 'middle', 'ring', 'pinky']
    #Now, iterate across finger joints, up to 3, group controls, and parent them
    for side in sideList:
        for boney in boneyList:
            for i in range(1, 4, 1):
                #Check if boney is thumb, and joint number is 3
                if (boney!='thumb') or (i!=3):
                    ctrlDup(side, boney, i, ctrlOrig)
                    nullGrouper(side, boney, i, ctrl)
                else:
                    pass

    print("It's done.")

handCtrls()

有几个“print”命令只是用来检查变量是否被传递。谢谢大家!
