How would you add more usernames? [closed]

Okay, your best bet is to use an array storing all the usernames. That way you don't have to keep using 'or' since it's an operator.

I am not entirely sure why you are using a LocalScript for your checks since this can be abused by exploiters, but it's your personal preference I guess.

Players = game:GetService('Players')
Player = Players.LocalPlayer

local usernameList = {'bob123', 'username', 'robloxadminguy123'} -- Store all the usernames here.

function checkUsername(Player)
    local nameString = Player.Name
    for _,v in pairs(usernameList) do -- loop through the table
        if string.lower(v) == string.lower(nameString) then -- use string.lower for cap sensitivity
            return true -- if username found, return true
        end
    end
    return false -- otherwise no username found, false
end

if checkUsername(Player) then
    -- rest of code here
end -- end the if statement

A breakdown of the code would be, the array stores the data and the function loops through that data to check if a string matches the data, if it does then it'll pass the if statement.

Use the **or **statement

ex:

if game.Players.LocalPlayer.Name == "username 1" or "username 2" or "username 3" then
