We’ve added three toggle properties in the game - which works fine - but the settings aren’t preserved when we quit. We need to save those settings so the next time you run the game, they persist.
First, we’ll define our settings file in
var settings_file = "user://settings.save"
Next, we’ll add saving/loading functions for the three game settings that we want to save.
func save_settings(): var f = File.new() f.open(settings_file, File.WRITE) f.store_var(enable_sound) f.store_var(enable_music) f.store_var(enable_ads) f.close() func load_settings(): var f = File.new() if f.file_exists(settings_file): f.open(settings_file, File.READ) enable_sound = f.get_var() enable_music = f.get_var() self.enable_ads = f.get_var() f.close()
save_settings() at the end of
set_enable_ads(). Also, in
Screens.gd we need to save the state when the sound/music settings change, so add
settings.save_settings() in each of those parts of the
Another problem we’ll have is when the game starts, the icons in the settings menu won’t reflect the state that we just loaded from the save file. We can set that in
register_buttons() which is already looping through all buttons to connect their signals:
for button in buttons: button.connect("pressed", self, "_on_button_pressed", [button]) match button.name: "Ads": if settings.enable_ads: button.text = "Disable Ads" else: button.text = "Enable Ads" "Sound": button.texture_normal = sound_buttons[settings.enable_sound] "Music": button.texture_normal = music_buttons[settings.enable_music]
The other thing we’ll add in this part is an “About” screen. This is where we’ll let the player know what the game’s all about and link to its license and to this page, since it is a tutorial game.
Complying with license terms is very important. You can find out what’s required by Godot here: Complying with Licenses. Note that the art you’re using may also require credit, links, or other acknowledgement.
To reach it, we’ve added a new button on the “Title” screen:
The button is setup just like the others - add it to the “buttons” group so that it will get registered. In the
Screens.gd, add another
match for this button’s name:
Here’s what the “About” screen looks like:
Extending “BaseScreen.tscn”, we’ve added a
TextEdit and another container for a single “Home” button.
TextEdit, set BBCode enabled and put the following in the Text property:
