Hand Out the Gauntlet

A Tool every player holds, with a glowing Handle

Active

🎯

Goal for this step

A tool called the Glitch Gauntlet, given to every player when a round begins.

1A Tool is a held item in Roblox. It needs a child part called exactly Handle.
2When the player clicks or taps the tool, the Activated event fires. That is our shove.
3We build the tool in code on the server and put it in the player's Backpack.

ObbyServer (Script)

local function giveGauntlet(player)
    local backpack = player:FindFirstChildOfClass("Backpack")
    if not backpack then return end

    local tool = Instance.new("Tool")
    tool.Name = "Glitch Gauntlet"

    local handle = Instance.new("Part")
    handle.Name = "Handle"
    handle.Size = Vector3.new(1.2, 1.2, 1.6)
    handle.Color = Color3.fromRGB(255, 60, 90)
    handle.Material = Enum.Material.Neon
    handle.Parent = tool

    tool.Parent = backpack
    tool.Activated:Connect(function()
        shove(player)          -- step 2 fills this in
    end)
end

💡

Run giveGauntlet(player) for every player at the start of a round. On a phone the player taps the tool icon in their hotbar, on a computer they click, and on a controller they press the button. One tool, every device.

The Shove

Push everyone in front of you away, hard enough to send them off the edge

Locked

🎯

Goal for this step

Find nearby players in a cone in front of you and launch them away.

1Loop over every other player and measure the distance to them.
2Check they are in front of you using the dot product of your facing direction.
3Add a burst of speed to their character, away from you and slightly upward.

ObbyServer (Script)

local Players = game:GetService("Players")
local RANGE, POWER, UP = 14, 65, 16

local function shove(player)
    local root = player.Character.HumanoidRootPart
    local origin = root.Position
    local look = root.CFrame.LookVector

    for _, other in ipairs(Players:GetPlayers()) do
        if other ~= player then
            local otherRoot = other.Character and other.Character:FindFirstChild("HumanoidRootPart")
            if otherRoot then
                local away = otherRoot.Position - origin
                if away.Magnitude <= RANGE and look:Dot(away.Unit) >= 0.35 then
                    otherRoot.AssemblyLinearVelocity =
                        away.Unit * POWER + Vector3.new(0, UP, 0)
                end
            end
        end
    end
end

💡

The dot product is a maths trick that tells you the angle between two directions. A value near 1 means "right in front of me", near 0 means "to the side", negative means "behind me". We accept anything above 0.35, so a wide cone in front.

Check the other player is close and in front, then push them away:

if away.Magnitude <= RANGE and look:(away.Unit) >= 0.35 then
    otherRoot.AssemblyLinearVelocity = away.Unit * POWER + .new(0, UP, 0)
end

Hint: the method that compares two directions, and the type for an X Y Z value.

Rank and Eliminate

Keep the fastest players, remove the rest, send them to spectate

Locked

🎯

Goal for this step

At the end of a round, put the players in order and cut the bottom of the list.

1Collect every player with how far along the course they got.
2Sort them, best first, with table.sort.
3Keep the top slice and mark everyone else as eliminated.

ObbyServer (Script)

local function rankAndCut(field, keep)
    table.sort(field, function(a, b)
        return a.progress > b.progress      -- further along = better
    end)

    local survivors = {}
    for i, entry in ipairs(field) do
        if i <= keep then
            survivors[#survivors + 1] = entry.player
        else
            eliminate(entry.player)       -- out of the match
        end
    end
    return survivors
end

💡

How big is keep? Make it a percentage that scales with the crowd. With 8 players keep about 5, with 40 keep about 20. Never let it drop below the number you need for the final. Our Config says FINAL_SIZE = 5.

Build the Final Arena

A grid of tiles with a ring number, ready to be eaten away

Locked

🎯

Goal for this step

A circular-looking platform built from square tiles, each tagged with a ring number.

1Make a grid from -6 to 6 in both directions. That is a 13 by 13 floor.
2For each tile work out its ring, how far it is from the centre.
3Store the ring on the tile with SetAttribute, so we can find and remove the outer ring later.

MapGen (ModuleScript)

function mapgen.buildArena(parent)
    local rings = 6
    for gx = -rings, rings do
        for gz = -rings, rings do
            local ring = math.max(math.abs(gx), math.abs(gz))
            local tile = newPart(parent, Vector3.new(12, 2, 12),
                Vector3.new(gx * 12, 0, gz * 12), palette[ring + 1])
            tile:SetAttribute("Ring", ring)
        end
    end
end

💡

The centre tile is ring 0. Everything around it is ring 1, then ring 2, and so on out to ring 6 at the edge. Deleting a whole ring at once gives you that shrinking battle-royale feel.

The Arena Shrinks

Every few seconds the outer ring falls away, until one player is left

Locked

🎯

Goal for this step

Delete the outermost ring on a timer and crown the last player standing.

1Count down, and when the timer hits zero remove the highest ring left.
2Anyone standing on the fallen ring drops into the void and is out.
3Stop when one player remains. They are the champion.

ObbyServer (Script)

local ring = 6
while #alive > 1 do
    task.wait(11)                       -- SHRINK_EVERY seconds
    shrinkRing(ring)
    ring = ring - 1
end

local function shrinkRing(n)
    for _, tile in ipairs(arenaFolder:GetChildren()) do
        if tile:GetAttribute("Ring") == n then
            tile:Destroy()                 -- the edge falls away
        end
    end
end

🔧

Players who fall below the arena should be knocked out. Check root.Position.Y each frame; if it drops below the arena, that player is out. Do not respawn them, this is the final.

👨‍👧

Tip for a fair final: give the gauntlet a small damage value in the final too, so a well-timed shove can knock someone out. Around 34 damage, so three hits finishes them. That keeps it a real deathmatch, not just a pushing contest.

Keep shrinking while more than one player is alive:

while #alive  1 do
    task.wait(11)
    shrinkRing(ring)
    ring = ring - 1
end

Hint: one character. "more than one player alive" means the count is greater than 1.

Champion and Publish

Show the winner, then publish your game for friends to play

Locked

🎯

Goal for this step

Celebrate the winner and put your game online.

1Set a Won attribute on the champion and fire a RemoteEvent so their screen shows a big banner.
2Click File then Publish to Roblox, give the game a name and a description.
3Set it to Public in Game Settings so anyone can join, then test it from the Roblox website.

ObbyServer (Script)

local function crown(champion)
    champion:SetAttribute("Won", true)
    event:FireAllClients("Champion", champion.Name)
end

💡

You now have a complete party game: a lobby, a match loop, three procedural map themes that never repeat, a shove gauntlet to push people off, elimination, and a shrinking last-one-standing final. Push people off the map is the whole point, and now you can.

👨‍👧

Where next: try adding a sound when the ring drops, or a speed boost pad, or a second gauntlet that pulls players instead of pushes. The Config file is yours to play with.

Why does the server decide who is eliminated and who wins?

ABecause the client cannot draw platforms

BSo players cannot cheat; the server is the referee

CBecause the server has better graphics
