I am making an onready variable, and I need it to check for a node, however I also need it to check for the nodes duplicates. And since duplicates in Godot have a number after them I can’t just do:

onready var x = get_parent().get_node("x")

So how can I also check for duplicates?

HI,
an easy way would be to use groups. Put your x-node in a group like “x_nodes”. then get them with

var all_the_x_nodes = get_tree().get_nodes_in_group("x_nodes")

read about it here:

Hi!
Thanks very much, you seem to be answering all my questions :slight_smile:

I was wondering if there is a way to do this without using groups, since calling a group requires a change in some other code which I dont want to change.

well … in theory you can scan the tree for any instance.

do cou know the call get_node_or_null() with that you can try to get a node

for i to range(0,10):
    var node = get_node_or_null("x"+str(i))
    if node:
        do something( node )
