How to Make a Roblox Obby with AI in 30 Minutes

Obbies (obstacle courses) are the gateway drug of Roblox development. They have a clean game loop: get from start to finish without dying. They're easy to scope. And they're consistently among the most-played genres on the platform.

With AI tooling, you can build a complete obby — multiple stages, working checkpoints, killer lava floors, a leaderboard — in about half an hour. This guide walks through it step by step.

What you need

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 on paper. A good 10-stage obby usually 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 boss room (a complex multi-mechanic stage)

You don't have to follow this exactly — the point is to have an escalation. Same difficulty for all 10 stages = 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 teleport-on-touch checkpoint 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. Use the rest of the difficulty curve from the list I gave earlier.

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

This step takes ~3 minutes. The result is a playable rough draft.

Step 3: Generate the checkpoint system

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 CheckpointStage = N. When a player touches it, the server saves Stage = N in their leaderstats. When they die, the server respawns their character at the position of 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.Checkpoints and a small modification to StarterCharacterScripts to handle respawn positioning.

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.

This handles itself in 30 seconds. If you want a more dramatic effect — knockback, particle burst, sound effect — you can 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:

A FinishPad Part with a Touched server script
A DataStore-backed leaderboard that tracks fastest finish times across all players
A ScreenGui that pops up 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 keeps people engaged.

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

Each of these is a 30-second AI request:

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

Step 7: Test the whole thing

This part is non-negotiable: play your obby start to finish before publishing. AI catches a lot but not everything. Common issues you'll find:

A jump that's just too far (player can't physically clear it)
A checkpoint pad that's slightly above the floor (player walks under it and never saves progress)
A lava floor with a gap big enough to skip (players will find it)

For each issue, send the AI the bug:

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

Iterate until the obby is fun.

Step 8: Publish

File → Publish to Roblox As → New Game. Pick a thumbnail (the AI can generate this with 3D model generation rendered to an image), set a title, and you're live.

For best results, name it something that includes "obby" — search-wise that genre word still drives most discovery on Roblox.

Variants you can build with the same template

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 — 100 stages, each named by difficulty rating
Story obby — each stage has a piece of a narrative on a TextLabel

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