Instancing a node and call a function

Question

Hello reader!

I'm having a small trouble with a inconsistence (Possibly i don't understand something). I'm instancing a node and calling a function, for some reason the variables are initialized from inside of node, but from outside spritenode is nil, if i use getnode instead the aparently initilized variable it works.

extends KinematicBody2D

export var speed = 0
var new_pos

# Nodes
onready var direction_node = get_node("Direction")
onready var sprite_node = get_node("Sprite")

func _fixed_process(delta):
    #if (direction_node != null):
    new_pos = (direction_node.get_global_pos() - get_global_pos()).normalized()
    move(new_pos * speed * delta)

func _ready():
    set_fixed_process(true)

func set_texture(var tex):
    sprite_node.set_texture(tex)
    # This works..
    # get_node("Sprite").set_texture(tex)

func set_direction(var dir):
    get_node("Direction").set_pos(dir)

func _on_VisibilityNotifier_exit_screen():
    queue_free()

I'm calling set_texture() from Player.gd, instancing this way:

var bullet = preload("res://entities/bullets/Bullet.tscn").instance()
var bullet_texture = preload("res://resources/textures/pickups/special.png")
bullet.set_texture(bullet_texture)
get_node("../..").add_child(bullet)

I would appreciate help, thanks.

PD: I know my english is not perfect.

Answer 1

sprite_node is referenced onready. ready signal is not emitted until the node enters to the tree, this means you have to add it first before calling set texture

var bullet = preload("res://entities/bullets/Bullet.tscn").instance()
var bullet_texture = preload("res://resources/textures/pickups/special.png")
get_node("../..").add_child(bullet)
bullet.set_texture(bullet_texture)

No way! That was the problem, now i know ready is called when the node enters to the tree, the reason is the most important part, thank you!

I'm not certain if this will solve your problem, but try adding the child before calling the function. I have a feeling it's not able to find the Sprite child, because the node is not yet part of the scenetree.
