I’m trying to run the code below, but I’m getting the following error:
Invalid access to property or key ‘timeout’ on a base object of type ‘null instance’.
extends Sprite2D
var speed = 400
var angular_speed = PI
func _ready():
var timer = get_node("Timer")
timer.timeout.connect(_on_timer_timeout)
func _process(delta):
rotation += angular_speed * delta
var velocity = Vector2.UP.rotated(rotation) * speed
position += velocity * delta
func _on_button_pressed():
set_process(not is_processing())
func _on_timer_timeout():
visible = not visible
Please, help me!!

Can you share a screenshot of the scene tree where this script is attached to?
It means that your timer variable is null, ie not actually referencing to a timer.
You create the timer variable and assign it here:
`var timer = get_node("Timer")`
This means there is no child node named “Timer”. And this node needs to be a child node of the Sprite2D node that you attach your script.
Thank you very much for your reply, but there is indeed a child node with the Timer. See the screenshot.
When you run the project, do you run node_2d scene or sprite_2d scene?

Try to drag the timer in while holding ctrl to make it an onready variable, then use that instead of get_node().

This is it.sprite_2d.tscn is the main scene, so you’re most likely running this scene when you hit Play, not the node_2d.tscn that you want to run.
I’m pretty sure you are running sprite_2d scene. Can you double check this?
