(Maya Python) 如何通過 GUI 功能運行單選選項按鈕？

Question

通常，當我運行帶有單選按鈕選項的腳本時，您會選擇一個單選按鈕選項，然后使用該按鈕激活它。 我曾經把我的菜單 gui 放在一個函數之外：但是自從我學會了導入 Maya 腳本后，我開始將我的菜單界面包裝在一個 GUI 函數中，這意味着我的單選按鈕技術現在不再有效。 我也不知道如何讓它工作。 腳本本身很簡單：只需在導入腳本后選擇一個單選按鈕選項，然后使用按鈕創建一個形狀：至少它應該如何工作。 相反，我沒有得到任何錯誤，也沒有創建任何形狀，我不知道是什么壞了。

myWindow = cmds.window("cubeWin",t='DS shapeDemo V1',w=200, h=500, toolbox=True)
column = cmds.columnLayout(adj=True)
#Creates variable to indicate the check box status. 1=Checked 0=Not Checked. 

cubeNum1 = 0
cubeNum2 = 0


#Creates Button funtion. 
def defaultButtonPush(*args):
       #The Print checks if button is pushed and what is the check box status. 
       print "Button is pushed."
       print cubeNum1
       #Check box argument finds the status of the variable and determines what to do. 
       #Eather create a cube or display a error dialog box.
       if cubeNum1 == 1:
        print "Cube Creation sucessful"
        cmds.polyCube()

       print "Button is pushed."
       print cubeNum2
       if cubeNum2 == 1:
        print "Sphere Creation sucessful"
        cmds.polySphere()


def gui(*args):
    #Creates check box. 
    #In the onCommand Script (onc) and offCommand Script (ofc) flags all commands must be made in between double quotes.
    cmds.radioCollection()
    cmds.radioButton(label='Cube',align='left',onCommand="cubeNum1 = 1", offCommand="cubeNum1 = 0")
    cmds.radioButton(label='Sphere',align='left',onCommand="cubeNum2 = 1", offCommand="cubeNum2 = 0")
    #Creates Button.
    cmds.button( label='Execute', command=defaultButtonPush ,align='left' )

cmds.showWindow()

這是修改后的腳本。 問題是腳本的范圍。 “onCommand”在其自己的范圍內執行，該范圍具有自己的“cubeNum”變量。

def action_button(*args):

    print "Button is pushed", repr(args)
    if shape_selector == 1:

另一種方法是僅在需要時讀取單選按鈕狀態
