Foo is a base class and assigns its own sprite with its _init. Its extension, bar, has additional data necessary for its extensions, which need to assign variables with their _init. However, this means that two _init calls must be made, which seems like it's impossible. Is there a way to refactor this to be possible without just duplicating the sprite-assignment code across every extension with a custom _init call?

@abstract
class_name Foo
extends Node

var sprite: Sprite2D;
var spriteImage: String;

func _init():
  add_child(sprite);
  sprite.texture = ImageTexture.create_from_image(Image.load_from_file(spriteImage));

@abstract 
class_name Bar
extends Foo

enum placeholder {
  A,
  B,
  C
};

var whichFromPlaceholder: int;

@abstract
class_name Child_of_Bar
extends Bar

func _init():
  whichFromPlaceholder = A
