Get node name and parent

RajDarge

I am struggling with this bit of code for what seems like foreever. 
i am trying to print a scence object next to its parent 

But whenever I have an non-root object the recursive function just returns undefined. 

function getParentRecurse(nodein){	//print(nodein.name);	if (nodein.isRootNode())	{		return nodein.name;	}	var newparent = nodein.getNodeParent();	getParentRecurse(newparent);}function getSceneGeom(){	var oNodes = Scene.getNodeList();	for (a_idx = 0 ; a_idx < oNodes.length ; a_idx++)	{		var oObject = oNodes[a_idx].getObject();		if (oObject)			{				var curNode = oNodes[a_idx];				var localObjName = getParentRecurse(curNode);				var curPrint = localObjName + "|" + curNode.name;				print(curPrint);			}	}}getSceneGeom();

this is the output:

if if you uncomment line 3 you get

Result:

I am not sure why I keep getting undefined as the result from the recursive function?

I think you just need to change the last line of your recursive function to include a return statement, so it reads:

return getParentRecurse(newparent);

Otherwise, you are only returning nodein.name up one level in the stack and it doesn't emerge to be assigned to localObjName.

Recursion is never pretty, and in Javascript it's really ugly.  Pity there isn't a 'getRootNode' convenience function somewhere.

You could short-circuit a certain amount by checking to see if the parent inherits DzBone and if it does using .getSkeleton() to skip to the figure.

Fixed it with one word! Seems i still don't understand how to write recursive functions. 

@richard - I think I will take that on board to simplify the code. I always feel uncomfortable with recursion - it's like staring into the abyss.  Clambering iteratively up and down Heirarchies is not always efficient though. 

Just need to figure out the details of all the inrinsic classes and what they mean. Instances, groups etc. didn't know DS even had these things.

Does anyone know what the pane "UI widget map" is meant to do? I can see it bullds a UI class structure, but documentation and even functionality on this is sparse ? Is it so you can eventually customise the UI with the SDK?

Just for completeness before I modify the script so much it will be unusable to others here is the working version: the recursive function is still there for reference, but is not called anywhere, I used the .getSkeleton() method to get the figure that the prop is attached to (not sure why its not displaying the code snippet as one ?)
