Core Systems
Gun Tool Script
-- StarterPack/Gun (Tool script)
local tool = script.Parent
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local shootEvent = ReplicatedStorage:WaitForChild("ShootEvent")
local fireRate = 0.15 -- seconds between shots
local damage = 25
local canShoot = true
tool.Activated:Connect(function()
if canShoot then
canShoot = false
-- Raycast from camera
local ray = Ray.new(
tool.Handle.Position,
(mouse.Hit.Position - tool.Handle.Position).Unit * 300
)
-- Fire to server
shootEvent:FireServer(mouse.Hit.Position)
-- Muzzle flash effect
local flash = tool.Handle:FindFirstChild("MuzzleFlash")
if flash then
flash.Enabled = true
wait(0.05)
flash.Enabled = false
end
wait(fireRate)
canShoot = true
end
end)
Server Hit Detection
-- ServerScriptService/ShootHandler.lua
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local shootEvent = ReplicatedStorage:WaitForChild("ShootEvent")
shootEvent.OnServerEvent:Connect(function(player, targetPosition)
local character = player.Character
if not character then return end
local gun = character:FindFirstChildOfClass("Tool")
if not gun then return end
local origin = gun.Handle.Position
local direction = (targetPosition - origin).Unit * 300
local raycastParams = RaycastParams.new()
raycastParams.FilterDescendantsInstances = {character}
local result = workspace:Raycast(origin, direction, raycastParams)
if result then
local hitPart = result.Instance
local hitCharacter = hitPart.Parent
local humanoid = hitCharacter:FindFirstChild("Humanoid")
if humanoid and humanoid.Health > 0 then
humanoid:TakeDamage(25)
if humanoid.Health <= 0 then
-- Award kill
local ls = player:FindFirstChild("leaderstats")
if ls then
ls.Kills.Value = ls.Kills.Value + 1
end
end
end
end
end)
Respawn System
-- ServerScriptService/RespawnSystem.lua
local Players = game:GetService("Players")
Players.PlayerAdded:Connect(function(player)
player.CharacterAdded:Connect(function(character)
local humanoid = character:WaitForChild("Humanoid")
humanoid.Died:Connect(function()
-- Death counter
player.leaderstats.Deaths.Value = player.leaderstats.Deaths.Value + 1
-- Respawn after 5 seconds
wait(5)
player:LoadCharacter()
end)
end)
end)
Team Deathmatch
-- ServerScriptService/TeamDeathmatch.lua
local Teams = game:GetService("Teams")
local redTeam = Teams:FindFirstChild("Red")
local blueTeam = Teams:FindFirstChild("Blue")
local SCORE_TO_WIN = 50
local scores = { Red = 0, Blue = 0 }
local function checkWin()
for team, score in pairs(scores) do
if score >= SCORE_TO_WIN then
-- Announce winner
-- Reset match
scores.Red = 0
scores.Blue = 0
end
end
end
Map Design Tips
- Symmetrical layouts for fair team games
- Multiple sight lines at different ranges
- Cover objects (walls, crates, vehicles)
- Spawn protection zones
- 3-lane design (standard FPS map structure)
