Roblox daily reward script

A reason to come back tomorrow: a player gets coins the first time they join each day, and the time is saved so rejoining doesn't pay out again.

Where it goes

1You need a Coins stat that saves: the saving script makes one.
2Publish your game, then in Studio open File, Game Settings, Security and turn on Enable Studio Access to API Services.
3In the Explorer, hover over ServerScriptService, press +, choose Script and paste this in.

How it works

UpdateAsync reads the time of their last reward and writes the new one in a single step, so two servers can't both pay out.
Returning nil from it leaves the saved time as it was, which is what happens when it isn't time yet.
The coins are added only after the save worked, so a failed save never gives a reward that isn't recorded.

Make it yours

Change the reward or the wait: REWARD is the coins, and DAY_SECONDS is how long until the next one.
Tell the player: Fire a RemoteEvent where the coins are added, and show a message from a LocalScript. The script generator can write that part.

Want something more? The script generator can write it: “A daily reward with a streak: more coins for each day in a row, with a screen that shows the streak”
