Export node path to a singleton for access by other nodes?

Question

Is it possible to esport a node path to a singleton script so that it can be accessed by other nodes even if it changes its position in the tree?
Let's say I have a node which is is being accessed by other nodes via getnode. In getnode I'm prviding full paths from root. But, if that node needs to move for any reason (eg, I want to reparent it) the path will change and I will have to update the path in all scripts currently accessing the node. I'm looking for a way to make godot find the node wherever it happens to be in the tree. I was thinking, if I could somehow export its path to a global singleton and access it from there?

Answer 1

right, here's how i got it to work (let me know of there is an easier way):

Singleton script

onready var path_to_node

------

Sought Node script

func _ready()
Singleton.path_to_node = self.get_path()

-----

Other nodes (which need to access sought node)' script

var sought_node = get_node(Singleton.path_to_node)

Answer 2

Storing the path in a singleton will still loose reference once the node is moved unless it is updated. An easier way to do this is to store the node itself in the singleton and use get_path() if necessary. It is also possible to use find_node() like this

get_node("/root/scene node").find_node("name of node")

wow, didnt know you could find nodes that easily in a hierarchy. I need to try this. Thanks!
