Create a simple Roblox game for kids

This is a simple Roblox guide to create a basic floor is lava obstacle course, I created it to go through with my son, so he could learn a bit of coding and build his first video game.

🛠️ Part 1: Setting up the “Brain” (Coding in VS Code)

Open VS Code. In the new project folder, create two files inside the src/server folder.

1. The Lava Script

Copy and paste this into a new file named LavaScript.server.luau. This makes red blocks dangerous!

-- 1. Setup the "Lava" rules
local CollectionService = game:GetService("CollectionService")
local DAMAGE_AMOUNT = 5 -- ⚡ CHANGE THIS: Use a bigger number to kill faster!
local TICK_RATE = 0.5   -- ⏱️ CHANGE THIS: Use a smaller number to damage faster!

local function onTouch(otherPart, lavaPart)
    local character = otherPart.Parent
    local humanoid = character:FindFirstChild("Humanoid")

    if humanoid then
        -- Don't start two loops at once
        if humanoid:GetAttribute("IsOnLava") then return end
        humanoid:SetAttribute("IsOnLava", true)

        repeat
            humanoid.Health -= DAMAGE_AMOUNT
            task.wait(TICK_RATE)

            -- Check if we are still touching this lava block
            local stillTouching = false
            for _, part in ipairs(lavaPart:GetTouchingParts()) do
                if part:IsDescendantOf(character) then stillTouching = true break end
            end
        until not stillTouching or humanoid.Health <= 0
        
        humanoid:SetAttribute("IsOnLava", false)
    end
end

-- Connect the logic to any block with the "Lava" tag
local function setupLava(part)
    part.Touched:Connect(function(otherPart) onTouch(otherPart, part) end)
end

for _, part in ipairs(CollectionService:GetTagged("Lava")) do setupLava(part) end
CollectionService:GetInstanceAddedSignal("Lava"):Connect(setupLava)

2. The Win Script

Copy and paste this into a file named WinnerScript.server.luau. This makes the finish line work.

local WIN_PART_NAME = "WinPart"

local function onWin(otherPart)
    local character = otherPart.Parent
    local player = game.Players:GetPlayerFromCharacter(character)

    if player then
        -- Create a big message at the top of the screen
        local message = Instance.new("Hint")
        message.Text = "🎉 " .. player.Name .. " REACHED THE END! 🎉"
        message.Parent = game.Workspace
        
        -- Make it sparkle!
        local sparkles = Instance.new("ParticleEmitter")
        sparkles.Parent = otherPart
        
        task.wait(5) -- Message stays for 5 seconds
        message:Destroy()
        sparkles:Destroy()
    end
end

game.Workspace:WaitForChild(WIN_PART_NAME).Touched:Connect(onWin)

🎮 Part 2: Mastering the View (How to move)

Navigating a 3D world is like playing a game. Here are the “Pro” controls for moving around the Studio viewer:

Action	Control
Move Around	Use W, A, S, D (Just like a game!)
Look Around	Hold the Right Mouse Button and move the mouse.
Go Up / Down	Press E to go up, Q to go down.
Teleport to Object	Select a part in the Explorer and press F (Focus).
Slow Down	Hold Shift while moving to move the camera slowly for detail work.

🏗️ Part 3: Building the World (Roblox Studio)

Now, switch to Roblox Studio. You need to build the objects the scripts are looking for.

1. The Lava Blocks

1. Click Part at the top to make a block.
2. Change its Color to Red and Material to Neon in the Properties window.
3. Crucial: Open the Tag Editor (View Tab) and check the box for Lava.
4. How to make it harder: In VS Code, change DAMAGE_AMOUNT to 100 to make it a “1-hit-kill” block!

2. The Spinning Whacker

1. Make a small block on the floor and Anchor it (This is the “Base”).
2. Make a long thin beam (The “Spinner”) and put it on top. Do NOT anchor it.
3. In the Model tab, click Create -> Hinge. Click the Base, then click the Spinner.
4. In the Properties for that Hinge:
   • Change ActuatorType to Motor.
   • MotorMaxAcceleration: Set to 1000.
   • AngularVelocity: Set to 5.
   • 🚀 CHANGE THIS: Make AngularVelocity a bigger number (like 20) to make it spin super fast!

3. The Win Pad

1. Make one last block at the end.
2. In the Properties window, change its Name to exactly: WinPart.
3. Change its color to Gold!
