Struggling to add & re-scale scene with Control Node root inside a Node2D scene

Help

Godot Version

Godot v.4.4.1

Overview

I have two scenes; one which is my main game (root) and another which represents cards in my game. The cards in the card scene are very large, and I would like to scaled them down as I bring them into root, but I am struggling to achieve this through GDScript code.

Project info

This is a very small project I whipped up to demonstrate my struggles.

I wish I could upload a ZIP of my project, but I don’t seem to be able to.

Here is all the info:

I have only two scenes:

root.tscn

  Root (Node2D)
  ├── Hand (Control)
  ├── CardToRoot(Button)
  ├── CardToHand(Button)

and card.tscn

  Card (Control)
  ├── CardImage (TextureRect)
  ├──├── CardText (Label)

Root has attached root.gd as a script:

extends Node2D
var card_scene := preload("res://card.tscn")


func add_card(size: Vector2):
	var card := card_scene.instantiate() as Control
	add_child(card)

	card.scale = size


func _on_card_to_root_button_up() -> void:
	add_card(Vector2(0.1, 0.1))

Hand has attached hand.gd as a script:

extends Control
var card_scene := preload("res://card.tscn")


func add_card(size: Vector2):
	var card := card_scene.instantiate() as Control
	add_child(card)

	card.scale = size


func _on_card_to_hand_button_up() -> void:
	add_card(Vector2(0.1, 0.1))

and CardToRoot & CardToHand are attached to their respective functions in the two scripts.

More details about my issue

In the 2D editor, when viewing card.tscn, I can select the Card node and modify its Scale via the Scale Mode tool (shortcut S) which changes the Scale values in the Inspector (Control > Layout > Transform > Scale).

This is perfect for me as it scales the Card and all of its children uniformly (kind of like resizing an image in Paint).

However when I try to achieve the same through code I don’t have much success.

Running the project

When I run the project:

  • the Add to Root button doesn’t display a new card at all.

  • the Add to Hand button successfully adds the image in the place it should, but the scaled down CardText is proportionally different to the scaled down CardImage.

Appreciate any help you can provide!

Change Root from a Node2D to a Control.

P.S. You can upload screenshots.

P.P.S. You can always upload a project for free onto GitHub and share the link with people here.

Thanks for the GitHub idea, didn’t cross my mind:

Your suggestions solved the problem for the Add to Root button - it now generates the card AND the text is scaled properly.

However, the behavior of the Add to Hand button hasn’t changed; card is added in the correct place and the TextureRect seems scaled correctly, but the Label is not scaled proportionally.

I find that quite weird, since Hand is a Control, so it should in theory act identically?

Also what are the implications of creating a game with root node Control vs root node Node2D?

Label scaling is weird because fonts. Hopefully someone with more experience with that can give you some tips there.

None.

You could have also solved your problem by adding a CanvasLayer node to your Node2D and then putting your Control hierarchy under that. I didn’t suggest that because you have no need to be using a Node2D with what you’ve described.
