	fire()
	var Bullet_instance = Bullet.instantiate()
	Bullet_instance.position = get_global_position()
	Bullet_instance.rotation = rotation_degrees
	Bullet_instance.apply_impulse(Vector2(),Vector2(bullet_speed, 0).rotated(rotation))
	get_tree().get_root.call_deferred("add child", Bullet_instance)
	await get_tree().create_timer(0.4).timeout

Just this. Not “:” this. Only this :

if input.is_action_just_pressed():
fire()
