Thank you for that information. With it attached to a node in the scene, the functions are not getting called, automatically.
I have it attached to a Spatial node, which is attached to the players game piece. Would the players game piece have to be new? Because it already is part of the scene. It makes me think it's not getting processed!
I prefer making manual calls for this one specific node anyways. So it's working out really well. But I think I could be doing something incorrect with the nodes.
