Python Script for Querying Joints in a Scene

[johngrivas582]

I’m trying to create a loop that will cycle through a scene query for joints and create a locator on each joint, using python, any Ideas ?

Hello @johngrivas582 ,

Hope you're doing fine.

This is a very old script I had written.

It does what you've requested, give it a try on your scene file. Let me know if it works for you and yes tweak it for your convenience.

import maya.cmds as mc
import codecs

#jnt_selection
sel = mc.ls(sl = True)
jnt_hie_lst = []
#print(sel)

#for_loop_for_appending_jnt_hie_in_lst_and_creating_controllers
for s in sel:   
    jnt_hie = mc.select(s, hi = True)
    jnt_hie_sel = mc.ls(sl = True)
    print (jnt_hie_sel)
    jnt_hie_lst.append(jnt_hie_sel)
    for j in jnt_hie_sel:
        new_name = codecs.encode(j)
        new_crc = mc.spaceLocator(name = '%s_ctrl' %new_name)
        new_grp = mc.group(name = '%s_ctrl_grp' %new_name)
        new_par = mc.parentConstraint(j, new_grp)
        mc.delete(cn = True)
        app = mc.parentConstraint(new_crc, j)
#print(jnt_hie_lst)

#preserve_ctrls_lst
ctrls_lst = []
#for_loop_for_querying_the_jnt_and_and_appending_the_query_in_the_ctrls_lst
for j in jnt_hie_lst:
    jnt_qry = mc.select(j)
    jnt_qry_sel = mc.ls(sl = True)
    for j_qry in jnt_qry_sel:
        mc.select(j_qry)
        mc.ls(sl = True)
        jnt_par_qry = mc.parentConstraint(tl = True, query = True)
        print(jnt_par_qry)
        jnt_par_qry_pop = jnt_par_qry.pop()
        ctrls_lst.append(jnt_par_qry_pop)
#print(ctrls_lst)

Hi!

So the code posted way quite flawed.

1) it needs selection to be actve

2) It does preserve some controls you never talked about...

The script you need is very simple:

import maya.cmds as mc

joints = mc.ls(type= "joint")

for j in joints:
    
    loc = mc.spaceLocator(n= "{0}_LOC".format(j))
       
    mat = mc.xform(j, m= True, ws= True, q= True)
    mc.xform(loc, m = mat, ws = True)

It's a python script so you'll need to run it from a python tab.

I hope it helps!
