Nodes don't know there "level", and as they can have multiple parents the "level" isn't necessarily unique. One does have to ask what exactly you mean by "level" though as it's not normally something scene graph users need, you are the first person I recall ever asking for this. > Or is it something I would have to work out by traversing the tree and > then storing it myself?? > I'm guessing my level you mean how far nested the node is from the root of the scene graph? If so then just use a NodeVisitor that has a TRAVERSE_PARENTS TraversalOrder and just count how long the NodePath that it accumulates gets. Just trying to avoid rewriting something that may already be there > As it's a very unusual thing to ask for then perhaps you are going about things in a way that isn't necessarily appropriate. I think it'd be useful explain what exactly you mean by "level" and what you need it for. Robert.
