I need it for my game, so that the Developers can get Extra Features, This would be used in order so a Hacker can not access The Devs features Easily, But The Problem Is I dont know how, Any help in a script or something would be helpful.
Hello. Your request is simple and easy. First way is, if you are using a PlayerAdded function you can do:
game.Players.PlayerAdded:connect(function(player) local playerid = player.userId end)
or, another way is with a LocalScript... You can do: local playerid = game.Players.LocalPlayer.userId
I hope this answered your question!
For your "Dev Features", you can change their names in the script to their IDs and then where your script says something of the sort as player.Name
you can change to player.userId
