Hello!
I have a Node2D with this script:
@onready var recipe_items : Array = []
@onready var recipe_quantities : Array = []
func add_item(item, quantity):
print("in 'add_item' recipe")
print("recipe_items: ", recipe_items)
recipe_items.append(item)
recipe_quantities.append(quantity)
and the line recipe_items.append(item) returns the error Invalid Call. Nonexistent function 'append' in base 'Nil'.
and yes, the print("recipe_items: ", recipe_items) returns recipe_items: <null>
But I create the Array with the @onready, doesn’t that mean that when the Node2D is instantiated, the array is created “first”?
I do that in another script:
@onready var recipe_scene = preload("res://recipe.tscn")
-- stuff --
var recipe_instance = recipe_scene.instantiate()
for item in added_items:
print("item in for loop: ", item)
print("item[0] in for loop: ", item[0])
recipe_instance.add_item(item[0], item[1])
None of the above print() returns null. But this line jumps to the func add_item(item, quantity) at the top, which then gives the error that the array recipe_items is null.
Shouldn’t var recipe_instance = recipe_scene.instantiate()start the line @onready var recipe_items : Array = [] hence, NOT be null?
I’m confused.
Thank you!
