为什么按代码复制关节不起作用?

原学程将引见为何按代码复制闭节没有起感化?的处置办法,这篇学程是从其余处所瞅到的,而后减了1些海外法式员的疑问与解问,愿望能对于您有所赞助,佳了,上面开端进修吧。

为什么按代码复制关节不起作用? 教程 第1张

成绩描写

我在Maya中经由过程代码创立多个闭节,这便是我想要做的。创立它们,并像如许将它们树立为女对于象...

L_Arm0一IK女级的L_ARM_00IK女级

L_Arm0一FK女级的L_ARM_00FK女级

L_ARM_00IKDriver女级L_Arm0一IKDriver女级L_Arm0二IKDriver

L_Arm0一的L_ARM_00混杂女项L_Arm0二的混杂女项

但是当我运转代码时,会创立第1个闭节L_ARM_00IK、L_ARM_00FK、L_ARM_00IKDriver、L_ARM_00Blend

但是它们的子代其实不是被创立的。我做错了甚么?仿佛出有经由过程界说DIPLICATE_CHAIN。

def ikfkchain(name, side, parent, joints, fktemplate, iktemplate, pvtemplate, fkcolor, ikcolor):



fk_joints = duplicate_chain(joints, None, "_JNT", "Fk_JNT")
ik_joints = duplicate_chain(joints, None, "_JNT", "Ik_JNT")
ik_driver_joints = duplicate_chain(joints, None, "_JNT", "IkDriver_JNT")
blend_joints = duplicate_chain(joints, None, "_JNT", "Blend_JNT")





def duplicate_chain(joints, parent, replace_what, replace_with):
new_joints = []
new_joints_parent = parent

for jnt in joints:
 new_jnt = cmds.duplicate(jnt, n=jnt.replace(replace_what, replace_with), po=True)[0]
 if new_joints_parent:
  cmds.parent(new_jnt, new_joints_parent)


 new_joints_parent = new_jnt 
 new_joints.append(new_jnt)

 return new_joints

推举谜底

瞅起去您只是在轮回中前往,这意味着您的函数只履行1次轮回,而后前往,没有会退1步轮回。

只需以下变动代码便可修复:

def duplicate_chain(joints, parent, replace_what, replace_with):
 new_joints = []
 new_joints_parent = parent
 
 for jnt in joints:
  print(jnt)
  new_jnt = cmds.duplicate(jnt, n=jnt.replace(replace_what, replace_with), po=True)[0]
  print(new_jnt)
  if new_joints_parent:
cmds.parent(new_jnt, new_joints_parent)
 
 
  new_joints_parent = new_jnt 
  new_joints.append(new_jnt)
 
 return new_joints

也便是说,在复制Maya中的对于象时,默许情形下,Maya也会复制该对于象的全部子体条理构造。

您不妨只做如许简略的工作:

from maya import cmds

top_joint = cmds.ls(selection=True)

duplicated_top_joint = cmds.duplicate(top_joint)

这将复制您的全部条理构造。复制闭节链时,这平日便足够了,由于我们平日愿望复制全部链。

而后,您只需从条理构造的底部开端重定名便可:

def rename_jnts(top_jnt, replace_what, replace_with):
 new_joints = cmds.listRelatives(top_jnt, allDescendents=True, fullPath=True) # we use fullPath so that each of the names contain the full hierarchy, in order to rename properly
 new_joints.append(top_jnt)
 new_joints.sort(key=len) # we sort by length to get the joints in hierarchical order
 new_joints.reverse() # we reverse the list to get the longer names first, since these are long names that means that the joints at the bottom of the hierarchy will be first in that list, and the first ones in the hierarchy will be last, this avoids renaming the top joints first and having Maya not find the other ones because their long names will have changed.
 for jnt in new_joints:
  short_name = jnt.split("|")[⑴] # first we split the long name by the pipe (|) character and keep the last token to get only the short name 
  new_name = short_name.replace(replace_what, replace_with) # We build the new name by replacing the proper token
  cmds.rename(jnt, new_name) # rename
