Hello all,
I have been digging into the Maya API dungeons recently to get myself up to
speed and familiar with the Maya API.
I have found myself recently digging through hierarchies to get all nodes
of a prefix or of type. I find myself constantly using:
for i in pm.listRelatives(object):
if i.startswith('prefix'):
do stuff...
So I decided to write myself a small plugin for a learning task that does
this for you.
Plugin: https://gist.github.com/ben-hearn-sb/cc5b0ebc5de41fc1f1c937e5b3f3359d
The only problem is the speed of the plugin, I put the plugin and the
original for i in relatives in 2 functions and used timeit in the maya
script editor.
The normal list relatives function was faster which seriously confused me
because I am sure that the API is supposed to be much faster at processing
information, I have a feeling I have some serious inefficiencies in my
plugin so any tips would go a long way to help me out!
Here is the Maya script editor testing:
import maya.cmds as cmds
getObjPluginPath = "path to get_objects_under_node.py"
cmds.loadPlugin(getObjPluginPath)
sel = cmds.ls(sl=True)
def pluginWay():
for s in sel:
cmds.getObjsUnderNode(s, fn='c_')
def normalWay():
for s in sel:
myList = []
for i in cmds.listRelatives(s, ad=True, fullPath=True):
if i.startswith('c_'):
myList.append(i)
#print myList
import timeit
timeit.Timer(pluginWay).timeit(number=500)
timeit.Timer(normalWay).timeit(number=500)
