I can do a test play, but the players all show up with Displayname "player" which I would like to customize. Is it possible?
I do not belive that you can change the name of the players but generaly the players are displayed as "player" but has different names in the game.Players so if you run a script that prints every player that joined you will most likely see
Player1 Player2
I tested this with a simple script
local Players = game:GetService("Players") Players.PlayerAdded:Connect(function(player) print(player.Name) end)
