Making variables change across scenes

It does run, but the variable it needs to continue down the chain never changes to true.
All the relevant code:

class_name squareBlock
extends Sprite2D

@onready var square_block: squareBlock = get_node("/root/Node2D/Blocks/squareBlock")
@onready var square_block_hitbox: Area2D = $squareBlock
@onready var in_play_piece: Sprite2D = get_node("/root/Node2D/inPlayPiece")
@onready var next_piece: Sprite2D = get_node("/root/Node2D/nextPiece")
var main = mainGame.new()
var pieceName = "squareBlock"

func _process(delta: float):
	if varStor.sq_ready == true:
		print("block ready")
		if varStor.activePieces.front() == pieceName:
			attachBlock(square_block, in_play_piece)
		elif varStor.activePieces.back() == pieceName:
			attachBlock(square_block, next_piece)

func attachBlock(whatToAttach, attachTo):
	whatToAttach.position = Vector2(attachTo.position.x, attachTo.position.y)

and the global variables:

extends Node2D

var sq_ready := false

var activePieces: Array[String] = ["squareBlock", "lBlock"]


func _on_start_timer_timeout():
	sq_ready = true
22

What does this print when placed in the global script? Does it print more than once?

func _ready() -> void:
    print(get_path())
23

It prints this block:

/root/varStor
/root/Node2D/Blocks/squareBlock/variableStorage
/root/Node2D/Blocks/variableStorage
/root/Node2D/variableStorage
/root/Node2D/squareBlock/variableStorage
24

That’s a lot of variable storages! The only one that is really a global is /root/varStor, and it’s created automatically by the Global/Autoload/Singleton system. However, you added the script .gd as a Global which does not create any of the children (the timer) or connections to signals (it’s timeout) that you expect, instead you can add the scene .tscn as a Global and it will.

25

So add the global script as a scene or add the scenes as globals?

26

You should have one scene with the specified script on the root node. Add that scene as a global varStor, delete all other variableStorage nodes.

Add the scene varStor.tscn as a global?
