I vaguely remember submitting this as a bug and getting a 'Yes, we know'
from Autodesk.
Anyway, giving the name right away only messes with the spaceLocator
command.
I remember spotting it in one other command, but I can't remember which one
it was.
Since Maya selects the newly created item you can actually query the
selection as a workaround! :)
import maya.cmds
def safeSpaceLocator(*args, **kwargs):
""" Wrapper around spaceLocator command since it doesn't return unique
names correctly if name argument is provided """
maya.cmds.spaceLocator(*args, **kwargs)
return maya.cmds.ls(sl=1)
The same fix works for PyMel of course.
If you'd rather stay away from querying selections because you might feel
it's the root of all evil.
Then here's another workaround, create the node with the createNode command.
print maya.cmds.createNode('locator', name='test')
If you want to have a fixed command without querying selection that still
allows you to manipulate it with argument like the default spaceLocator
command, then here's a draft:
import maya.cmds
def safeSpaceLocator(*args, **kwargs):
createKwargs = {}
name = kwargs.pop('name', kwargs.pop('n', None))
if name is not None:
createKwargs['name'] = name
locator = maya.cmds.createNode('locator', **createKwargs)
if args or kwargs:
maya.cmds.spaceLocator(locator, e=1, *args, **kwargs)
return [locator]
Note that it doesn't allow to use the last safeSpaceLocator() command in
edit mode.
It's trivial to implement if someone wants to monkey patch Maya's command
plus has the urge to work around querying the selection.
