How to make a battlegrounds game in Roblox Studio

Battlegrounds games are arenas where players fight with combos and abilities. Everything depends on combat feeling responsive while staying fair, which means the client plays the animation instantly and the server decides who actually got hit.

The core loop

Every battlegrounds game comes down to one loop that players repeat. Build this first, in grey blocks:

1. Spawn into the arena
2. Fight with M1 combos and abilities
3. Get kills, die, respawn
4. Unlock new characters or moves

Systems you need

Build order

1. 1

   Arena

   A flat map with cover and edges. Combat is easier to tune on a simple map.

2. 2

   M1 punch

   The scripts below: one LocalScript, one server Script, one RemoteEvent.

3. 3

   Animations and effects

   Animate the punch on the client right away so it feels instant; add a hit sound and a small particle on the server's confirmed hit.

4. 4

   Combos and abilities

   A 4-hit combo (reset if the player stops clicking), then one ability with a long cooldown.

5. 5

   Kills and leaderboard

   Tag the attacker on the victim's Humanoid and give the kill to the last player who hit them.

The key script: M1 punch with a server hitbox

Where it goes: ReplicatedStorage > Punch (RemoteEvent) + two scripts.

• Insert a RemoteEvent named Punch into ReplicatedStorage.
• The first script is a LocalScript in StarterPlayer > StarterPlayerScripts; the second is a Script in ServerScriptService.

-- StarterPlayerScripts > Combat (LocalScript)
local ContextActionService = game:GetService("ContextActionService")
local punch = game:GetService("ReplicatedStorage"):WaitForChild("Punch")

local function onPunch(_, state)
	if state == Enum.UserInputState.Begin then
		punch:FireServer()
		-- Play your punch animation here so it feels instant.
	end
	return Enum.ContextActionResult.Pass
end

-- "true" also creates an on-screen button for phones and tablets.
ContextActionService:BindAction("Punch", onPunch, true, Enum.UserInputType.MouseButton1)

--------------------------------------------------------------------
-- ServerScriptService > CombatServer (Script)
local Players = game:GetService("Players")
local punch = game:GetService("ReplicatedStorage"):WaitForChild("Punch")

local COOLDOWN = 0.45
local DAMAGE = 10
local lastPunch = {}

punch.OnServerEvent:Connect(function(player)
	local now = os.clock()
	if now - (lastPunch[player] or 0) < COOLDOWN then return end
	lastPunch[player] = now

	local character = player.Character
	local root = character and character:FindFirstChild("HumanoidRootPart")
	if not root then return end

	local params = OverlapParams.new()
	params.FilterType = Enum.RaycastFilterType.Exclude
	params.FilterDescendantsInstances = { character }

	-- A 5x5x5 box just in front of the attacker.
	local box = root.CFrame * CFrame.new(0, 0, -3)
	local alreadyHit = {}
	for _, part in workspace:GetPartBoundsInBox(box, Vector3.new(5, 5, 5), params) do
		local humanoid = part.Parent:FindFirstChildOfClass("Humanoid")
		if humanoid and humanoid.Health > 0 and not alreadyHit[humanoid] then
			alreadyHit[humanoid] = true
			humanoid:TakeDamage(DAMAGE)
		end
	end
end)

Players.PlayerRemoving:Connect(function(player)
	lastPunch[player] = nil
end)

How it works

• Split the code at the dashed line: the top half is the LocalScript, the bottom half the server Script.
• The client only asks to punch. Damage, range and cooldown live on the server, so changing values on the client does nothing.
• alreadyHit stops one punch from damaging the same player several times through different body parts.

How battlegrounds games make Robux

• Characters or move sets as game passes — the genre's main income.
• Emotes and cosmetic auras.
• Private servers so friends can practice and duel.

You receive 70% of what players spend on game passes and developer products; Roblox keeps 30%.
