Problem with saving player position

CryAlone

i have this code :-1:

extends Node

export(Script) var game_save_class

var save_vars = ["player_pos"]
func _input(event):
	
	if event is InputEventKey and event.scancode == KEY_J:
		save_world()
	if event is InputEventKey and event.scancode == KEY_I:
		load_world()



func verify_save(world_save):
	for v in save_vars:
		if world_save.get(v) == null:
			return false
	


func save_world():
	var new_save = game_save_class.new()
	new_save.player_pos = $Player.position
	
	var dir = Directory.new()
	if not dir.dir_exists("res://saves/"):
		dir.make_dir_recursive("res://saves/")
	
	
	ResourceSaver.save("res://saves/save_1.tres", new_save)
	
	



func load_world():
	var dir = Directory.new()
	if not dir.file_exists("res://saves/save_1.tres"):
		return false
		
	var world_save = load("res://saves/save_1.tres")
	if not verify_save(world_save):
		return false
		
	$Player.position = world_save.player_pos
	return true

it gives me this error : Invalid call. Nonexistent function 'new' in base 'Nil'. PLS HELP IM LOSING MY MIND

Ok, I have three things to say.

Firstly, your code can be more readable if you surround them with "```". You should use "`" when surround a single code line or fragment. I'll format it for you this time. :)

Secondly, if you look at the line that's calling new, you'll see that it's calling it from game_save_class which is an exported property. So the most likely reason why you're getting the error is because that property is null.

Thirdly, it looks like your post got stuck in the moderation queue. Make sure that you have confirmed your email address. :)

You might want to look over the forum rules, I've edit the post this time.

Like I said. game_save_class doesn't have any value, so you need to give it a value. Are you sure that you assigned a script to the property in the editor?

Also worth a mention that the exported variables can have a default(/fallback) assigned in the same line that is defining the variable.

export(type) var var_name = default_value
