Enum Not Working with @export Annotation

Help

Hi friends.

I added the following GD Script to Global.

extends Node
enum Fish {
	BALOON = 1,
	RED = 2,
	BLUE = 3,
	GREEN = 4,
	PINK = 5,
	GRAY = 6,
	FOSIL = 7
}

Then, I created the following Resource code.

extends Resource
class_name FishSpecs

@export var fish: Fish

This error occurs:

res://Script/fishScripts/FishSpecs.gd:5 - Parse Error: Node export is only supported in Node-derived classes, but the current class inherits "Resource".

However, if I define the enum in the Resource (FishSpecs.gd) file, this error does not occur.

If I’m not mistaken, if I define the enum in the Resource (FishSpecs.gd) file, it will redefine the enum every time a new Resource instance is created. This would lead to unnecessary memory usage.

How can I solve this issue, assuming the enum is defined externally? Or what is the correct approach?

Your enum isn’t defined in FishSpecs.gd, Fish is aglobally recognized node of which your enum is shadowing (you may get a warning for this).

Adding that script as a global creates a instance of the type it extends, so there is now a Node in your game’s scene tree that has no data but defines a enum for itself.

You could preload the script to access it’s defined properties or give it a class_name

extends Resource
class_name FishSpecs

const FishData = preload("res://my_global_fish_script.gd")
# or give the script `class_name FishData`

@export var fish: FishData.Fish
