Unlocking attributes via python

[Craig_Lamorte]

Hi,

How would i go about unlocking translate, rotate, scale if they have been locked (like if you right click them in channel box and click lock.  There will be a gray box surrounding that attribute when locked)

I have been trying to find out how to do it myself without much success.  The closest I have gotten was doing this command

pm.setAttr('poly.translate', lock=False)

So this command did not work unlocking the attributes when I had locked them in the channel box through the UI.  The only way that command will work is if lock it by running the command with lock=True first...  Which is not very useful if it only unlocks it under certain conditions.

I cannot find any command that will unlock them after locking them through the channel box ui.

Thanks

Craig

The problem you are encountering is that you are trying to unlock translate and not translateX, translateY, and translateZ all separately.

I typically build a list of axis

axis = ['X', 'Y', 'Z']

and a list of transform attrs

attrs = ['t', 'r', 's']

and then run a nested for loop to unlock all of them.

for ax in axis:
    for attr in attrs:
        cmds.setAttr(obj+'.'+attr+ax, lock=0)

which basically ends up with

cmds.setAttr(obj+'.tX', lock=0)

etc

awesome that totally worked! thanks!

guess it doesn't like when i use just translate / scale / rotate to grab all 3

**edit - nevermind its working now, not sure why it wasn't working in the first place

One more question...  Trying to query whether the attribute is locked or not.  I tried this -

cmds.getAttr(obj+'.tx', lock=True)

 But all i am getting his False no matter if its locked or not...

This works for me:

import maya.cmds as cmds
objs = cmds.ls(sl=True)
for obj in objs:
    attrs = cmds.listAttr(obj)
    for attr in attrs:
        try:
            if cmds.getAttr("{0}.{1}".format(obj, attr), lock=True) == True:
                print "{0}.{1} is Locked".format(obj, attr)
            else:
                print "{0}.{1} is unlocked".format(obj, attr)
        except ValueError:
            print "Couldn't get locked-state of {0}.{1}".format(obj, attr)

Or to unlock all attributes on selected objects in pymel: 

import pymel.core as pm

for obj in pm.selected():
    for a in pm.listAttr(obj):
        obj.attr(a).unlock()

shorter, faster but less readable:

import pymel.core as pm
[obj.attr(a).unlock() for a in pm.listAttr([obj for obj in pm.selected()])]

your code was not completely correct
I've refined it a little)

objs = cmds.ls(sl=True)
axis = ['x', 'y', 'z']
attrs = ['t', 'r', 's']
for ax in axis:
    for attr in attrs:
    	for obj in objs:
    		cmds.setAttr(obj+'.'+attr+ax, lock=0)
