Iterate in subnet python

[tamagochy]

Hey,

I have subnet in obj with few geometry nodes inside. I need iterate all geo nodes and find all nulls inside each geo node.

How can I make this with python? All I have been trying gave me all null nodes in obj context  , but I need only from this subnet.

Thanks!

Hi, 

There are many ways to achieve what you're looking for. Here's one 

subnet = hou.node("/obj/my_subnet")
null_nodes = []
for child in subnet.children():
    if child.type().name() == 'geo':
        for sub_child in child.children():
            if sub_child.type().name() == 'null':
                null_nodes.append(sub_child)

Hope it helps

import toolutils
toolutils.findAllChildNodesOfType(hou.node('/obj/geo1'), "null", dorecurse=True)

Wow toolutils cool.Thanks.

I found solution with generator

null = [y for y in g.children() if y.type().name() == 'null']

but good to know there is function for this
