hello, i wanted to create a system to save levels progress. i found a script posted by someone that does the thing, but whenever i save the game and get to load it it shows me this error message:
Invalid get index ‘level’ (on base: ‘Nil’)
Here is the script:
extends Node
var currentLevel
func _ready():
var dir = Directory.new()
if !dir.dir_exists("user://Saves"):
dir.open("user://")
dir.make_dir("user://Saves")
func get_level():
return get_tree().get_current_scene().get_filename()
func set_level(var levelName):
currentLevel = levelName
get_tree().change_scene(levelName)
var GameData = {
level=""
}
func save_game_state(var saveName):
var saveGame = File.new()
saveGame.open("user://Saves/"+saveName+".sve", File.WRITE)
var data = GameData
data.level = get_level()
saveGame.store_line(to_json(data))
saveGame.close()
func load_game_state(var saveName):
var loadGame = File.new()
if !loadGame.file_exists("user://Saves/"+saveName+".sve"):
print ("File not found! Aborting...")
return
var currentLine = {}
loadGame.open("user://Saves/"+saveName+".sve", File.READ)
while(!loadGame.eof_reached()):
currentLine = parse_json(loadGame.get_line())
currentLevel = currentLine["level"]
loadGame.close()
func new_game():
currentLevel = "res://level1.tscn"
set_level(currentLevel)

You didn’t say what line the error was on…

From what I see, it means GameData became null, but can’t say why. Something else in your project might be modifying it.
