Question about Remote Events

[forest tapir]

Let's say I want the server to show a GUI for all players, I could use a remote event with .OnClientEvent:Connect(function()) to make a GUI visible for all players. But what if, I want to make so the GUI will be visible for the player only if they meet a requirement (ex: having "a" in their name). How do I check each player's name inside the .OnClientEvent function?

understand something

localscripts run on a player's computer

so each player has their own localscripts

if the code is inside a local script you can use Players.LocalPlayer to get the player that is running the script

[forest tapir]

Yes, but how do I know what player it is "looping" through?

[forest tapir]

Yes I know that

[deft compass]

do you want to do the validation on the server or the client

[forest tapir]

client

[deft compass]

it might be vulnerable to exploiters if you do it on the client

Using :FireAllClients

:FireAllClients() sends a remote for all players right?

Ok gimme a sec

[deft compass]

you could just do

for player in Players:GetPlayers() do
  remote:FireClient(player)
end

and do the validation in the loop

[forest tapir]

Exemple:

There is a :FireAllClients() that sends a remote to all players (let's say se have "Player1", "Player2" and "Player3"). When I handle that remote, so using .OnClientEvent, I would like to check if the player has "3" in their name, if so, then do something (a function) else do nothing

[forest tapir]

oh yeah

forgot about that 😅

thx!

[forest tapir]

they exploit using client-side scripts?

if you wanna do it with guis

id reccomend

-- (serversided)
local players = game.Players

local function displayUI(letter)
  for i, player in pairs(players:GetChildren()) do
    --loop thru name
    local playerString = player.Name:split("") --
    for i, v in pairs(playerString) do
      if v == letter then
          local UI = player.PlayerGUI.ScreenGUI.Frame.Visible = true -- (example)
        print("player : " .. player.Name .. " had their UI turned on")
      end
    end
  end
end

local remote = ...
local letter = "a"
remote.OnServerEvent:Connect(function()
  displayUI(letter)
end

i dont really remember how :split works

string.split

youll have to look that up but this should be the basic premise of it
