Question
Hey all, I’ve been working on a scene that has a root of a Node2D and has a Sprite2D as a child. I want to be able to change the Sprite2D’s sprite from the editor when the scene is added as a child, so I figured I would do something like this:
@tool
extends Node2D
@onready var sprite : Sprite2D = %Sprite
@export var starter_texture : Texture:
get:
return sprite.texture
set(texture):
sprite.texture = texture
However, whenever I open the editor or run the game, I get this error:
ERROR: res://scripts/character.gd:10 - Invalid assignment of property or key 'texture' with value of type 'CompressedTexture2D' on a base object of type 'Nil'.
I assume this means that it’s running before the child nodes are initialized (base object of type ‘Nil’ is alluding to that). I’ve had a similar issue in the past, in which I used await get_tree().process_frame to wait until everything in the scene was initialized, but I don’t know how to do that here as it is in a getter/setter.
Here’s what my scene tree & whatnot look like:
I doubt that it will be related but here is the rest of the script:
@tool
extends Node2D
@onready var sprite : Sprite2D = %Sprite
@export var starter_texture : Texture:
get:
return sprite.texture
set(texture):
sprite.texture = texture
@onready var anims : AnimationPlayer = %AnimationPlayer
var flipped = false
func change_sprite(sprite: Texture) -> void:
anims.play("squish start")
await anims.animation_finished
sprite.texture = sprite
anims.play("squish end")
await anims.animation_finished
func flip() -> void:
if flipped:
anims.play("flip 360")
else:
anims.play("flip 180")
flipped = not flipped
await anims.animation_finished
