Here's the code I used to accomplish that task in PM_heatWeight:
def isATypeOf(node, type):
"""Returns true if node is of the given type, or inherits from it."""
if isinstance(node, basestring) and cmds.objExists(node):
return type in cmds.nodeType(node, inherited=True)
else:
return False
def listForNone( res ):
if res is None:
return []
return res
def getSkinClusters(mesh):
"""
Returns a list of skinClusters attached the given mesh.
"""
return [x for x in listForNone(cmds.listHistory(mesh))
if isATypeOf(x, 'skinCluster')]
Obviously, not all api, but the only call that I don't know of any
easy API conversion for is listHistory. I think in order to get an
equivalent result, you have to trace back through connections to
'inMesh' (or equivalent if you're not using a poly mesh), and check
for nodes that have their 'isHistoricallyInteresting' attribute set...
but I'm not positive.
Be interested to hear what others do for this...
