I want to make a kind of GUI that congratulates you if you have achieved an objective and unlocked a new area except that (after testing) everyone has the GUI which gives me a problem. If anyone ever knows the answer please put an example of code and not just text
have a gui that has a local script with something like:
local id = --your id
local plr = game.Players.LocalPlayer
if plr.UserId ~= id then --detect if player user id is not your user id
script.Parent.Visible = false --don't show gui
end
