To make a Roblox obby with AI, you generate four things in order: the stage geometry, a checkpoint system, the kill mechanics (lava), and a finish line with a leaderboard. With an in-Studio AI plugin each of those is one prompt, and the whole thing fits in about half an hour.

Obbies are the best first Roblox project there is. The loop is clean — get from start to finish without dying — it's almost impossible to over-scope, and the genre is consistently among the most-played on the platform. Here's the whole build.

What do you need to make an obby?

Roblox Studio (free download)
An AI Roblox plugin like Revix
A baseplate (start with the "Baseplate" template in Studio)

That's it. No models, no asset library, no Animation Editor.

Step 1: Plan the stages

Before generating anything, sketch out your stages. A good 10-stage obby has a difficulty curve like:

Tutorial — basic jumps
Slightly wider gaps
Moving platforms
Killer lava floors
Jumping over spinning logs
Disappearing platforms (timing-based)
Tightrope walk
Speed-jump puzzle
Wall jumps
Final room (a multi-mechanic stage)

You don't have to follow this exactly — the point is escalation. Same difficulty for all 10 stages is boring.

Step 2: Generate the stage layout

Open Studio. Open your AI plugin. Send something like:

Build a 10-stage obby starting at position (0, 5, 0). Each stage is roughly 50 studs long with a checkpoint pad at the start. Stages should escalate in difficulty. Stage 1 is wide flat platforms with small gaps. Stage 4 has lava floors that kill on touch. Stage 6 has platforms that disappear 0.5 seconds after a player steps on them.

The AI generates the geometry — Parts for platforms, lava floors as red Parts with a Touched script that kills players, and checkpoint pads at the start of each stage.

The result is a playable rough draft in a couple of minutes. It will not be balanced yet. That's fine — that's step 7.

How do obby checkpoints work?

Checkpoints are the magic that makes obbies feel fair. Without them, dying on stage 9 sends you back to stage 1 and players quit forever.

The pattern: each checkpoint is a Part tagged with a stage number. When a player touches it, the server saves that number to their leaderstats. When they die, the server respawns their character at the pad matching their saved stage.

Ask the AI:

Add a checkpoint system. Each stage's checkpoint pad sets the player's Stage leaderstat value. On respawn, teleport the player's character to the position of the pad matching their saved Stage.

The result is a server script in ServerScriptService plus respawn handling. Test it properly: touch checkpoint 3, jump off the map, confirm you respawn at 3 and not at spawn.

Step 4: Make the lava work

Killer floors are the most-loved-and-hated obby mechanic. The pattern is:

The floor is a Part with Material = Neon, red color
A server script connects to the Part's Touched event
When a player's character part touches it, set Humanoid.Health = 0

Ask the AI:

All Parts named "Lava" should kill any player whose character touches them.

Naming the Parts consistently is what makes this a one-liner — the script keys off the name, so every future lava Part works automatically. Want drama? Iterate: "When a player touches Lava, play a sizzle sound and emit fire particles for 1 second before they die."

Step 5: Add a finish line + leaderboard

The finish is where players land when they clear stage 10. Make it visually distinct (gold platform with a flag is the obby standard) and trigger the win condition.

Ask:

When a player touches the FinishPad, save their finish time to a DataStore-backed global leaderboard, then teleport them back to the start. Show a "You Finished!" UI for 3 seconds.

The AI generates the FinishPad Part and its Touched script, the DataStore-backed leaderboard, and the ScreenGui that pops on finish.

The leaderboard is the lifeblood of an obby — players come back to beat their own time. Even a simple "Top 10 Fastest Times" list gives people a reason to replay. For a nicer-looking board, see How to Create Roblox GUIs With AI.

Step 6: Visual polish

The default Studio Parts look bare. Spend the last 10 minutes making it look like a real game:

Generate decorative props with AI 3D model generation — torches, trees, ruins
Add background music with a Sound in SoundService
Set Lighting ambient + skybox to match a theme (volcano, ice world, neon city)
Give the UI a consistent font and color scheme

Each of these is a short AI request:

Add 10 torches along the obby path. Set lighting to a dusk theme with orange ambient.

Step 7: Test the whole thing

Non-negotiable: play your obby start to finish before publishing. AI catches a lot but not everything. What you'll typically find:

A jump that's just too far to physically clear
A checkpoint pad slightly above the floor, so players walk under it and never save progress
A lava floor with a gap big enough to skip — players will find it

For each issue, send the AI the specific fix:

The jump from stage 3 to stage 4 is too far. Move stage 4 closer by 5 studs.

Iterate until it's fun. This step is most of what separates an obby people finish from one they quit.

Step 8: Publish

File → Publish to Roblox As → New Game. Set a thumbnail, a title, and you're live.

Including the word "obby" in the title genuinely helps in-platform discovery — it's how players search the genre. Don't keyword-stuff it, though; a title that reads like spam converts worse than a clear one.

What else can you build from an obby?

The same skeleton supports a lot of related games:

Speed run obby — fewer obstacles, focus on time
Tower of Hell — single tall obby, no checkpoints
Difficulty chart obby — many stages, each named by difficulty rating
Story obby — each stage carries a piece of a narrative on a TextLabel

The AI can convert your base obby into any of these: "Convert this obby into a Tower of Hell — remove checkpoints, stack all stages vertically into one tower."

Frequently asked questions

Can a beginner make a Roblox obby with no coding experience?

Yes — an obby is the standard first project precisely because the mechanics are simple enough that AI-generated scripts work with little intervention. You'll still want to read what's generated. When a checkpoint misbehaves, understanding the script is what gets you unstuck. Luau for Beginners covers enough to follow along.

Why do my players respawn at the start instead of the checkpoint?

Three usual suspects: the checkpoint's Touched event isn't firing (the pad is buried in the floor or has CanTouch off), the stage value isn't saving to leaderstats, or your respawn code runs before the character finishes loading. Test each link separately.

How many stages should an obby have?

Ten is a good first target — long enough to have a difficulty curve, short enough that you'll actually finish and publish it. Add more once you know players are completing it. An unfinished 50-stage obby helps nobody.

Do I need DataStores for an obby?

Not for checkpoints within a single session — leaderstats in memory handle those. You need DataStores for anything that survives a rejoin: saved stage progress across sessions, and a global fastest-time leaderboard.
