Iterating down a hierachy

[Jeremy YeoKhoo]

Hey guys,

A relatively easy question for you Maya python API peeps. How would you traverse down a hierarchy of a DAG node. Essentially if a hierarchy tree has children of the same appended name, I want to duplicate a single tree of that child for every children

Thanks

Would MItDag possibly w/ MSelectionList be what you are looking for to find and traverse?

MItDag

MSelectionList

Yes, I am thinking the MItDag would be the trick

What I am trying to do is while traversing down a specified hierarchy of a DAG object, finding several objects containing a particular string/name within its children nested at different levels.Returning the name of those objects. However, I am guessing because the search essentially using a naming convention and not of a DAG type, maya.cmds would be a faster approach rather than using the MItDag method

Actually I started coding using the MitDag, and at the moment I want to find the deepest depth of a hierarchy. But realise that it doenst automatically allow me to do that.

dagIterator= OpenMaya.MItDag( OpenMaya.MItDag.kDepthFirst, OpenMaya.MFn.kInvalid )

selectionList = OpenMaya.MSelectionList()

OpenMaya.MGlobal.getActiveSelectionList( selectionList )

dgPath= OpenMaya.MDagPath ()

selectionList.length()

selectionList.getDagPath(0, dgPath) 

dagIterator.reset(dgPath)

dagIterator.depth()
