I do not understand what it is trying to tell me.

Error: Invalid call. Nonexistent function ‘instance’ in base ‘Nil’.
0 - res://Main.gd:13 - at function: _on_MobTimer_timeout

extends Node

export (PackedScene) var mob_scene


func _ready():
	randomize()

func _on_MobTimer_timeout():
	var mob_spawn_location = $MobPath/MobSpawnLocation
	mob_spawn_location.unit_offset = randf()

	var mob = mob_scene.instance()
	add_child(mob)

	mob.position = mob_spawn_location.position

	var direction = mob_spawn_location.rotation + PI / 2
	direction += rand_range(-PI / 4, PI / 4)
	mob.rotation = direction

	var velocity = Vector2(rand_range(mob.min_speed, mob.max_speed), 0)
	mob.linear_velocity = velocity.rotated(direction)

From my understanding Nil mean something is null, or doesn’t exist.

The error is under your Timeout function

So when you call the function instance() you made an invalid call. This means you cannot instance that scene. There may be a mistake with your file path. I’m not super familiar with packed scenes as I don’t ever use them. So instead I would suggest preloading the scene like this .

var scene = preload(“res://scene.tscn”).instance()

I hope that helps
