How Kids Can Build Their First Roblox Game: 6 Beginner Lua Scripts

Every week parents ask us the same question: "My kid plays Roblox all day. Can they actually learn to code with it?" Yes, and it is one of the best first steps into programming. Roblox Studio uses Lua, a small, readable language, and kids see the result of every line instantly in a 3D world.

Below are the 6 scripts we use in the very first lesson at our coding school. With them a child aged 8+ can build a complete mini obby (obstacle course) in about an hour. All scripts are free on GitHub: roblox-scripts-for-kids.

How to add a script in Roblox Studio

1. Open Roblox Studio and create a new Baseplate.
2. Insert a Part (Home → Part).
3. In the Explorer, hover over the Part, click + and choose Script.
4. Delete print("Hello world!"), paste the code, press Play (F5).

1. Kill brick (lava)

The classic obby trap. Anyone who touches the part is reset.

local brick = script.Parent

brick.Touched:Connect(function(otherPart)
    local humanoid = otherPart.Parent:FindFirstChildOfClass("Humanoid")
    if humanoid then
        humanoid.Health = 0 -- reset the player
    end
end)

What kids learn: events (Touched), variables, if statements.

2. Moving platform

local TweenService = game:GetService("TweenService")
local platform = script.Parent -- must be Anchored!

local info = TweenInfo.new(3, Enum.EasingStyle.Sine, Enum.EasingDirection.InOut, -1, true)
local goal = { Position = platform.Position + Vector3.new(20, 0, 0) }

TweenService:Create(platform, info, goal):Play()

What kids learn: services, vectors (X/Y/Z), and how changing one number changes the game's difficulty.

3. Door that opens on click

local door = script.Parent
local click = Instance.new("ClickDetector", door)

click.MouseClick:Connect(function()
    door.Transparency = 0.8
    door.CanCollide = false
    task.wait(3)
    door.Transparency = 0
    door.CanCollide = true
end)

4. Teleport pad

Name one part PadA (put the script inside) and another PadB:

local padB = workspace:WaitForChild("PadB")

script.Parent.Touched:Connect(function(otherPart)
    local root = otherPart.Parent:FindFirstChild("HumanoidRootPart")
    if root then
        root.CFrame = padB.CFrame + Vector3.new(0, 3, 0)
    end
end)

5. Leaderboard with coins

Put this one in ServerScriptService:

game.Players.PlayerAdded:Connect(function(player)
    local stats = Instance.new("Folder")
    stats.Name = "leaderstats" -- must be exactly this name
    stats.Parent = player

    local coins = Instance.new("IntValue")
    coins.Name = "Coins"
    coins.Parent = stats
end)

6. Coin pickup

The full version with respawn is in the GitHub repo. Together with the leaderboard it turns an obby into a real game with a score.

Put it together: a 60-minute first game

1. Build a path of platforms over a "lava" floor (kill brick).
2. Add one moving platform in the middle.
3. Put coins on hard jumps.
4. End with a door and a teleport back to the start.
5. File → Publish to Roblox and send the link to friends.

That moment when a friend plays their game is what keeps kids coding.

Tips for parents

• Age 8–10: start with Roblox and Scratch-style thinking; short 45–60 minute sessions work best.
• Age 11–17: after Roblox, move on to Python or web development (HTML, CSS, JavaScript).
• One-on-one lessons work much better than big groups: the child sets the pace, and every question gets answered.
