get_node -> null

Question

Hello,
Before trying a HTTPRequest, I want to simply print the object to change it later (TextureRect).

Scene is simple:

And HTTPRequest script even simplier:

extends HTTPRequest
onready var changery = get_node("TextureRect")
func _ready():
     print (changery)

get_parent works though, but I don't get why get-node is not in this case.
On Ubuntu 21.04

Did you ever have this behavior?

Answer 1

get_node() starts looking from node that called it. So, if you calling it from script of HTTPRequest, you are looking for childs of HTTPRequest. And since there is no node named TextureRect as child of your HTTPRequest, it returns null. If you want to make this code work, you need to reparent TextureRect to HTTPRequest, so tree would look like

Spatial
  - HTTPRequest
     - TextureRect

Thanks @AlexTheREgent!
I wouldn't like to change the tree. Only the path.
You're right though that without slash it's a child.

According to https://docs.godotengine.org/fr/stable/classes/class_node.html#class-node-method-get-node
onready var changery = get_node("/root/TextureRect") should work, but it's not.

I accept your reply since I can't honorably accept mine :)

You can also use relative path in get_node like get_node("..") to get parent.

Oh, my, I see my mistake
onready var changery = get_node("/root/Spatial/TextureRect")
