Roblox Fe Gui Script -

Here’s a safe, validated PvP button that only kills an enemy if they are within 10 studs.

LocalScript (Client):

local remote = game.ReplicatedStorage:WaitForChild("AttackRemote")
-- Assume target is selected from a list GUI
targetPlayer = "JohnDoe"
remote:FireServer(targetPlayer)

Server Script:

remote.OnServerEvent:Connect(function(attacker, targetName)
    local target = game.Players:FindFirstChild(targetName)
    if target and target.Character and target.Character:FindFirstChild("Humanoid") then
        local dist = (attacker.Character.HumanoidRootPart.Position - target.Character.HumanoidRootPart.Position).Magnitude
        if dist <= 10 then
            target.Character.Humanoid.Health = 0
        end
    end
end)

This respects FE because the server calculates distance and applies damage.

FE (FilteringEnabled) is a mandatory Roblox security setting that prevents a client (player) from directly modifying the game state for other players. A FE GUI script must use RemoteEvents or RemoteFunctions to communicate between the client’s GUI (local script) and the server (normal script). Without FE compliance, any GUI-based changes (e.g., giving tools, damaging players, moving parts) will only be visible to the exploiting client — not to other players. roblox fe gui script

The "Roblox FE GUI Script" is more than a code snippet; it is a mirror reflecting the fundamental tension of online multiplayer games. It exposes the fragile contract between client and server: the client must be trusted to show the game, but never to be the game. For every developer who writes a beautiful, animated menu using a LocalScript, an exploiter writes a false remote call disguised as a button press.

Ultimately, the most powerful FE GUI script is not the one that crashes a server or gives infinite health. It is the one that a developer writes to be unexploitable—where every visual effect is just a decoration, and every game-critical action is guarded by a skeptical, vigilant server. In the world of Roblox, FE never sleeps, and the GUI is always watching. Here’s a safe, validated PvP button that only

Key implication for GUIs:
If a client clicks a GUI button to give themselves a weapon, the server must validate that request. You cannot simply change a player’s tool from a local script.

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")
local event = ReplicatedStorage:WaitForChild("PlayerActionEvent")
local function onAction(player, action)
    if action == "Kill" then
        local char = player.Character
        local humanoid = char and char:FindFirstChildOfClass("Humanoid")
        if humanoid and humanoid.Health > 0 then
            humanoid.Health = 0
        end
    elseif action == "Respawn" then
        -- simple respawn using LoadCharacter
        player:LoadCharacter()
    end
end
event.OnServerEvent:Connect(function(player, action)
    -- Basic validation: only accept expected string values
    if type(action) ~= "string" then return end
    if action ~= "Kill" and action ~= "Respawn" then return end
    onAction(player, action)
end)

local player = game.Players.LocalPlayer
local remote = game.ReplicatedStorage:WaitForChild("GiveCoinEvent")
local button = script.Parent.TextButton
button.MouseButton1Click:Connect(function()
remote:FireServer()  -- Ask the server nicely
button.Text = "Request Sent!"
