@TwistedTwigleg said: Does the error display which line the Resource file not found: res:// is on or being triggered by?

My guess would be the change_scene function call on `` is causing the issue. Maybe add print(scene) after line 12 in the first code snippet and see what it shows? Maybe it is not loading it currently. I might also suggest adding print(scene) between lines 2 and 3 in the second code snippet, just to make sure everything is as expected.

Also, what is stored in scene when you save it to a file? The change_scene function takes a string that is the path to the scene file you want to load. If you pass a non-string to it, that could also be contributing to the issue.

(Small note: I fixed code format. You can just post the code with a single tab indent or surround it with three ~ on either side)

The error is on the continue button at "get_tree().change_scene(scene)", ive been trying to print the scene to see if is all alright but it says null over and over

edit: nvm i got it working, i put "scene = get_tree().current_scene.filename" in the level transition scene and it worked : ) thanks

I have this code

func save_data():
	var file = File.new()
	file.open("user://save", file.WRITE_READ)
	file.store_var(scene)
	file.close()

func load_data():
	var file = File.new()
	if not file.file_exists("user://save"):
		return false
	file.open("user://save", file.READ)
	scene = file.get_var()
	file.close()
	return true

when i hit continue

func _on_Continue_pressed():
	load_data()
	get_tree().change_scene(scene) 

it gives me this... Resource file not found: res://, why is that?

I have a continue button in the menu how do i tell Godot that i want to load the "parent" from the json file or how do i save the level that im on ?

in the player node i have this:

func save():
	var save_dict = {
		"filename" : get_filename(),
		"parent" : get_parent().get_path(),
		"pos_x" : position.x, 
		"pos_y" : position.y,
		"speed" : SPEED,
		"direction_x" : motion.x,
		"direction_y" : motion.y
	}
	return save_dict

and in the global script(save system) i have this:

func load_level():

	var level = "parent"


	var save_game = File.new()
	if not save_game.file_exists("user://" + name + ".save"):
		return 

	var save_nodes = get_tree().get_nodes_in_group("save")
	for i in save_nodes:
		i.queue_free()

	save_game.open("user://" + name + ".save", File.READ)
   
	while not save_game.eof_reached():
		var current_line = parse_json(save_game.get_line())
		
		if current_line == null:
			continue
		
		var new_object = load(current_line["filename"]).instance()
		get_node(current_line["parent"]).add_child(new_object)
		new_object.position = Vector2(current_line["pos_x"], current_line["pos_y"])
		new_object.motion = Vector2(current_line["direction_x"], current_line["direction_y"])
		

		for i in current_line.keys():
			if i == "filename" or i == "parent" or i == "pos_x" or i == "pos_y" or i == "direction_x" or i == "direction_y":
				continue
			new_object.set(i, current_line[i])
	
	save_game.close()

	func save_level():
		var save_game = File.new()
		save_game.open("user://" + name + ".save", File.WRITE)
	
		var save_nodes = get_tree().get_nodes_in_group("save")
	
		for i in save_nodes:
			var node_data = i.call("save");
			save_game.store_line(to_json(node_data))
	
	save_game.close()

	func delete_save_data():

	
		var dir = Directory.new()
	
		dir.open("user://")
	
		dir.list_dir_begin()

		while true:
			var file = dir.get_next()
			if file == "":
				break
			elif not file.begins_with("."):
				dir.remove(file)
	
		dir.list_dir_end()

@SIsilicon28 said: 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. :)

Ok thats nice and all, but how do i solve it?

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
