I’m getting this error and I’m not sure why.
For simplicity’s sake, let’s assume I have two scripts: animal.gd and farm.gd.

Animal.gd looks as following:

class_name Animal
var name

class Cow extends Animal:
   func _init():
     name = "Cow"

class Sheep extends Animal:
   func _init():
     name = "Sheep"

and Farm.gd looks as following:

const Animal = preload(".../animal.gd")
var animals : Array
func populate_farm():
  animals.append(Cow.new())
  animals.append(Sheep.new())

I’m getting the following errors: Identifier "Cow" not declared in the current scope., Identifier "Sheep" not declared in the current scope.

I’m not sure if I’m doing something wrong, but I have no idea how else to do this. I also can’t find anything online that explains how to do this. Any help?

Here the inner classes only exist inside the scope of the Animal class.
If you want to access them (outside of the Animal class), use Animal.Cow etc.
