I have an egg file I’ve exported from Blender 2.4 with chicken.
Here is the scene in Blender:
A cube with the tag “main”. The cube has a child cube itself.
I want in Panda to find the Cube by its tag, then access its children.
from panda3d.core import *
import direct.directbase.DirectStart
model = loader.loadModel('a.egg')
model.reparentTo(render)
node = model.find('**/=main')
for i in node.getChildren():
print i
i.setX(4)
run()node.getChildren() seems to also contain “node” itself! Why?
