If you want to indicate the folder where it'll be saved, the tutorials give the example of using ("user://")
, which will vary according to the OS.
Personally, I prefer using (./)
, as this defines the folder where the executable is. So, ./saves
would refer to the saves folder wherever the executable is, whether it is /home/bla/game
(for Linux) or C:/Games/Game/game
If you plan to have the game as HTML5, do use (user://)
, which will save to their browser's cache. Similar question here - https://godotengine.org/qa/30304/how-can-create-save-game-system-that-works-game-exported-html5
