Practical Gamemode Script Examples

Below are short, copyable Lua examples commonly used when building Roblox gamemodes. They are simplified for learning—adapt and expand them in Roblox Studio.

1) Leaderstats (Scoreboard)

-- Leaderstats: adds a Score IntValue for each player
local Players = game:GetService("Players")

Players.PlayerAdded:Connect(function(player)
  local leaderstats = Instance.new("Folder")
  leaderstats.Name = "leaderstats"
  leaderstats.Parent = player

  local score = Instance.new("IntValue")
  score.Name = "Score"
  score.Value = 0
  score.Parent = leaderstats
end)

2) Team Auto-Assign

-- Simple balanced team assigner
local Teams = game:GetService("Teams")
local Players = game:GetService("Players")

local function getSmallestTeam()
  local best, bestCount
  for _,t in pairs(Teams:GetChildren()) do
    if t:IsA("Team") then
      local count = #t:GetPlayers()
      if not bestCount or count < bestCount then
        best = t
        bestCount = count
      end
    end
  end
  return best
end

Players.PlayerAdded:Connect(function(player)
  local team = getSmallestTeam()
  if team then
    player.Team = team
  end
end)

3) Round Manager (basic)

-- Very simple round manager: pregame -> play -> postgame
local state = "pregame"

local function startRound()
  state = "play"
  print("Round started")
  -- spawn players, enable gameplay, start timers
  wait(60) -- round duration
  state = "postgame"
  print("Round ended")
  -- award points, cleanup
  wait(10)
  state = "pregame"
end

-- Example trigger
startRound()

4) Spawn Handler (use spawn locations)

-- Teleport player to a random SpawnLocation when they join
local Players = game:GetService("Players")
local spawns = workspace:WaitForChild("Spawns"):GetChildren()

Players.PlayerAdded:Connect(function(player)
  player.CharacterAdded:Connect(function(character)
    local humanoidRoot = character:WaitForChild("HumanoidRootPart")
    local spawn = spawns[math.random(1, #spawns)]
    humanoidRoot.CFrame = spawn.CFrame + Vector3.new(0, 3, 0)
  end)
end)

5) Tool / Weapon Pickup (server-side equip)

-- Give a starter sword when player touches a pickup part
local Players = game:GetService("Players")
local pickup = workspace:WaitForChild("SwordPickup")
local swordTemplate = game.ServerStorage:WaitForChild("StarterSword")

pickup.Touched:Connect(function(hit)
  local player = Players:GetPlayerFromCharacter(hit.Parent)
  if player then
    if not player.Backpack:FindFirstChild(swordTemplate.Name) and not player.Character:FindFirstChild(swordTemplate.Name) then
      local sword = swordTemplate:Clone()
      sword.Parent = player.Backpack
    end
  end
end)

6) Temporary Powerup (speed boost)

-- Speed powerup that lasts for 8 seconds
local POWERUP_DURATION = 8

local function applySpeedBoost(player, amount)
  local humanoid = player.Character and player.Character:FindFirstChildOfClass("Humanoid")
  if humanoid then
    local original = humanoid.WalkSpeed
    humanoid.WalkSpeed = original + amount
    delay(POWERUP_DURATION, function()
      if humanoid then
        humanoid.WalkSpeed = original
      end
    end)
  end
end

-- Example usage: call applySpeedBoost(player, 20) when picked up
