How do I reference an enum from an autoloaded script?

I have a file called that contains the following:

extends Node

enum Skill {

This file is autoloaded via the AutoLoad tab in Project Settings, with the name Skillmove and the Global Variable checkbox enabled.

In a scene that’s loaded later in the execution of the game, I have this line of code:

func _process(_delta):
	var backflip_enum = Skillmove.Skill.Backflip

which throws this error:

Invalid get index 'Skill' (on base: 'Node').

I have followed all the instructions for using player singletons here and code executed elsewhere that utilizes this enum appears to work fine; why is this happening?

That all seems correct to me. So, you’re only having an issue with this enum in a single scene? Is there something unique about that scene that could point to the problem?

Nothing, except that it’s part of a scene that’s instanced later instead of loaded at launch.

I can make it work if I do the following:

const SkillMoveType = preload("res://").Skill

func _process(_delta):
    var backflip_enum = SkillMoveType.Backflip

… however this defeats the purpose of preloading the script in the first place.

Test run it by adding a dummy scene to the tree and

func _ready(): 
    var test = Skillmove.Backflip     

Also double check SkillMove vs Skillmove in the name of the autoload symbol.

It is pointless to use autoload for this. You can use any form of static typing.
Option nr 1:
Keep all individual enums inside corresponding classes
Option nr 2:
Create enums class, that will only contain all constant data for other nodes to use or for autocomplecion purposes.

Either way, all You have to do is :

extends Node
class_name skillmove
enum Skill {}

Static node doesn’t even need to be loaded as singleton, it simply has to exist anywhere in your filesystem. You refer to it by its class, like var test = skillmove.Skill.Jump
