In gdscript, how do I reference a file-level variable or function from within a class in that file?

[Luminous Dark]

I'm trying to do something like this:

extends Control

var score : int = 0

class SampleClass:
	func function():
		if score > 0:
			print("Score is more than zero")

and I get an error saying "Identifier 'score' not declared in the current scope."
Something very similar happens if I try to call a function that is not in SampleClass from SampleClass. How am I supposed to handle this?

Do you mean a class-level variable?

extends Control

class SampleClass:
	var score : int = 0

	func function():
		if score > 0:
			print("Score is more than zero")

Or you might be meaning a "global scope" variable... in which case it might look like this in one file:

extends Node
classname SampleClass

var score : int = 0

... and you could then reference it in another script as:

extends Node

func update_score(new_score : int):
	SampleClass.score = new_score

See https://docs.godotengine.org/en/3.1/getting_started/workflow/best_practices/what_are_godot_classes.html

Note that the SampleClass could also be an Autoload, in which case you can omit the classname line because it's handled by the Autoload system in Project Settings.

See https://docs.godotengine.org/en/stable/tutorials/scripting/singletons_autoload.html

No, I meant defining an inner class within the script of another class, and having the inner class reference the global variables and functions of the outer class. I figured out how to do it by passing an initialization variable to the inner class that is the outer class, like this:

extends Control

var score : int = 0

class SampleClass:
	func _init(root, otherArgs):
		self.root = root
		self.otherArgs = otherArgs
		
	func function():
		if root.score > 0:
			print("Score is more than zero")

sample = SampleClass.new(self, 'initialization parameters')
