【问题描述】:
我是一名动画师,是编码初学者...感谢您的帮助!
我正在编写一个 Python 脚本来自动复制 Maya 中的控制器对象。它为角色手中的每个骨骼创建控制器。
它作为单个长函数工作得很好,但我想要一个主函数“handCtrls()”,在其中调用函数以执行各种任务。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“nullGrouper(side, boney, i, ctrl)”的行上出现错误,并且错误说“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”,虽然我会将该变量发送回“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“打印”命令只是为了检查变量是否被传递。谢谢!
