Question

我正在尝试选择多个曲线cvs

这些是我函数的代码

这是setArg函数：

import maya.cmds as mc from functools import partial

def setArg(CTS, option, *args):
    option = mc.radioButtonGrp(CTS, q=True, select=True)
    if option == 1:
        cvToSel = 'first'
        print cvToSel
    elif option == 2:
        cvToSel = 'last'
        print cvToSel
    return cvToSel

这是execute函数：

 def execute(cvToSel, *args):
    newSel = []
    curves = mc.listRelatives (type = 'nurbsCurve', shapes = True)
    if not curves:
        print ('no curves selected')

    #mc.select(clear = True)
    #print curves
    for crv in curves:
        len = mc.getAttr(crv+'.cp', s=True, multiIndices=True)
        cvSelect = mc.intFieldGrp('numberOfCvs', q = True, value1 = True)
        numCv = len - cvSelect

        if cvToSel == 'last':
            newSel = mc.select(crv+'.cv[%d'%numCv +':%d]'%len, tgl = True)
        elif cvToSel == 'first':
            newSel = mc.select(crv+'.cv[0' + ':%d]'%cvSelect, tgl = True)

    #mc.select(newSel, replace = True)

这是ui函数：

def ui():
    if mc.window('CV_Select', exists = True):
        mc.deleteUI('CV_Select')
    cvWin = mc.window('CV_Select', mxb = False)
    mc.columnLayout( adjustableColumn = True )
    mc.text( label = 'select curves' )

    mc.intFieldGrp( 'numberOfCvs', label = 'Number Of Cvs', value1 = 10 )

    ButtonOne = mc.radioButtonGrp( label='Type', labelArray2=['First CVs', 'Last CVs'], numberOfRadioButtons = 2)
    mc.button( label = 'Select CVs', command = partial(execute, ButtonOne),  align = 'center', aop = True)

    mc.showWindow('CV_Select')
     ui()

如何使用参数？

首先不要使用'len'来存储变量。这是一个非常有用的python函数... 这是一种方法。您需要将选择功能放在循环之外您可以使用-add标志，但是它可能真的很慢将第一个简历存储到变量中：（我在星期一之前没有玛雅人，但我希望它会有所帮助）

sel_curves = mc.ls(sl=1, dag=1, type='nurbsCurve')
if sel_curves:
    to_sel = []
    cvSelect = mc.intFieldGrp('numberOfCvs', q = True, value1 = True)
    for c in sel_curves:
        cvs = mc.ls(c+'.cv[:]', fl=True)
        nb_cvs = len(cvs)
        if cvSelect > nb_cvs:
            nb_cvs = cvSelect
        if cvToSel == 'last':
            to_sel += cvs[cvSelect:]
        elif cvToSel == 'first':
            to_sel += cvs[:cvSelect]
    cmds.select(to_sel, tgl = True)

只需回答您的评论问题：

def execute(CTS,*args):
    cvToSel = setArg(CTS)
