Hi, I would really appreciate if somebody could send me a script to use to save progress for players in a tycoon. Thanks.
What you are asking for isn't possible with a universal script. Data saving & loading mechanism is very game-specific. If your game is a tycoon, you need to save info such as which things did the player buy, and then when they rejoin, place those things back, so they don't have to rebuy them again. It's up to you on how you do that.
In order to save anything, you need to use roblox DataStores. You can read more about them here.
