The server script is the brain of the operation. This is where real logic happens, completely hidden from exploiters’ direct tampering. Server responsibilities include:
For the ultimate challenge, implement lasers that bounce off mirrors or reflective surfaces. This requires advanced raycasting with reflection calculation—essentially performing a raycast, then calculating a new direction based on the surface normal, and continuing until the beam has “bounced” a set number of times.
local player = game.Players.LocalPlayer local mouse = player:GetMouse() local replicatedStorage = game:GetService("ReplicatedStorage")
Instead of creating raw parts (which might not replicate well), the script creates Attachment instances inside your character's hand and spans a Beam instance from the hand to the target point. FE Laser Arm Script
For combat games, the script should use Raycasting . When the ray hits a Humanoid part, it triggers a health reduction.
-- Get arm position local arm = character:FindFirstChild("Right Arm") if not arm then return end
Tracks player input, mouse positioning, and fire rates. The server script is the brain of the operation
laserRemote.OnServerEvent:Connect(function(player, direction, targetPosition) local character = player.Character if not character then return end
In combat games, it can deal damage to other players (if the script successfully bypasses server checks, though this is harder in modern FE). 3. Customizable Aesthetics
Modify the Beam or Trail objects within the script to match your style. Neon materials are highly recommended to give that classic "sci-fi" glow. Security and Ethical Use When the ray hits a Humanoid part, it
Start your chosen script executor software before or during game loading.
For aspiring game developers, the FE Laser Arm Script is a fantastic entry point into learning and CFrame manipulation . These two concepts are the backbone of almost every modern FPS and action game on the Roblox platform.
