extends Node func _ready(): print(load_config()) # Should do something meaningful, but let's print for test purposes func load_config(): var path = "user://config.ini" # The path to load the file var config = ConfigFile.new() # Create a new ConfigFile object var default_options = { # Create a dictionary of default options "difficulty": "easy", "music_volume": 80 } var err = config.load(path) # Load the file from the disk if err != OK: # If there's an error return the default options return default_options var options = {} # Create a dictionary to store the loaded options # Get the values from the file or the predefined defaults if missing options.difficulty = config.get_value("options", "difficulty", default_options. difficulty) options.music_volume = config.get_value("audio", "music_volume", default _options.music_volume) return options # Return the loaded options
