How to make a Roblox game with AI

The options, side by side

They aren't rivals so much as different tools. A generator gives you a big head start; an assistant helps you change things after. Many creators will end up using two of them.

1. Roblox Assistant, inside Studio

Assistant is Roblox's own AI helper, built into Studio. You open it from Studio's top bar and type what you want. According to Roblox's Assistant guide, it can:

• write and edit scripts, and explain code you select;
• create, change and delete objects in your place, and insert assets from the Creator Store;
• generate 3D models from a text prompt or a reference picture;
• plan bigger changes first (a Planning Mode) so you can read the steps before anything happens.

Good for: small, specific jobs in a place you already have. "Make this door open when a player has 100 coins." "Why does this script error?" "Add a row of street lamps along this road."

Not so good for: designing a whole game for you. It works step by step on what you ask, so you still decide what the game is, in what order to build it, and how the pieces fit.

How to start: open Studio, open a place, click Assistant and describe one small change. Read what it plans, then test with Play. Roblox sets its own limits on some features (for example a daily number of generated models), so check the guide for the current details.

2. Roblox Build, in the Roblox app

In July 2026 Roblox announced Build, a creation tab in the Roblox app made for phones: you describe a game, get a first version, then edit, playtest, share it with friends or publish it. Roblox says it shares its back end with Studio, so a project started in Build can be continued in Studio.

Good for: making something on a phone, with no computer at all, and the official route inside Roblox.

Not so good for (yet): most people can't use it today. It started as an alpha in New Zealand and Roblox is adding countries over time, with an age check. We haven't been able to test it, so check Roblox's own announcements for what it can make and where it's available.

3. Claude with the Roblox Studio MCP server

MCP (Model Context Protocol) is an open standard that lets an AI app use other programs. Roblox Studio has an MCP server built in, so an AI app such as Claude can work inside your open Studio session: look through your game's objects, write scripts, run Luau code and test in play mode. Roblox's page Connect to the Roblox Studio MCP server has the setup: in Studio you open Assistant, go to Manage MCP Servers and enable Studio as an MCP server, then connect your AI app.

Good for: longer tasks where the AI needs to see your actual game: "Find every script that changes Coins and move that logic to the server", "Build a round system using the maps in ServerStorage and test it." It can check its own work by running the game, which a chatbot can't.

Not so good for: people who can't yet read what it's doing. It can change many things quickly, so save a copy first, review the changes, and test. It also needs an AI app and plan of its own, with its own costs.

How to start: follow Roblox's setup page, then begin with a read-only question ("Explain how this game's shop works") before asking for changes.

4. ChatGPT and other chatbots

The simplest way to use AI: ask a chatbot (ChatGPT, Claude, Gemini or another) for a script, then paste it into Studio. It's also great for learning: "Explain what Players.PlayerAdded does like I'm new to coding."

Good for: learning Luau, small scripts, fixing an error message you paste in, and brainstorming game ideas, names and update plans.

Not so good for: anything that depends on how your place is set up. The chatbot can't see your Explorer, so it guesses names and locations. Expect to fix paths like workspace.Map.Door by hand, and to paste errors back a few times.

Tips that make it work much better:

• Tell it where the script goes ("a Script in ServerScriptService") and paste the names of the objects it needs.
• Ask for "server-side checks" for anything to do with money, items or damage.
• Ask it to use current APIs (task.wait, not wait) and to wrap DataStore calls in pcall.

5. A whole game from one prompt (BloxMaps)

The BloxMaps Game Maker works the other way round: instead of helping you build piece by piece, it builds a complete first version. You describe a game in a sentence, like "a pet simulator with eggs in a candy world", and it builds:

• the map, with spawns and the places the game needs (shops, plots, a lobby);
• the UI: HUD, shop, menus;
• the gameplay systems and scripts for that kind of game, and saving;
• a shop with game passes and developer products already connected to Roblox's purchase prompts;

all in one Roblox Studio file (.rbxl). You watch each step build in your browser and see the result before paying anything. It knows 18 genres, from tycoons and obbies to horror and racing (browse them in the idea list). The pet simulator, grow and steal, anime tower defense formats are the most finished; the others are marked Beta on the page and may need a few extra setup steps.

Good for: getting from zero to a playable game fast, beginners who'd like to learn by changing a working game, and creators who want to test several ideas quickly.

Not so good for: a kind of game it doesn't know (it builds its closest format), or editing a place you already have (Assistant or MCP are better there). And it's a starting point: to make the game stand out you'll still change things, add your own ideas and keep updating it.

Cost: building and previewing is free: 3 previews a day on the Free plan (games, maps and UIs together), and the plans build more. Exporting the finished .rbxl costs $14.99 once per game, or is included with the Studio plan. See pricing.

Which one should you use?

• You have no game yet and want something playable today: start with a generator, then learn by changing it. On a phone with access to Roblox Build, that's the official way to try it.
• You have a game and want to change or fix one thing: Roblox Assistant.
• You have a game and a bigger job that touches many scripts: Claude (or another AI app) through the Studio MCP server, with a backup first.
• You want to learn to code: a chatbot as a patient tutor, while you type the code yourself.

A combination works well: generate the first version, open it in Studio, then use Assistant or an MCP-connected AI to change the parts you want different.

Mistakes AI makes in Roblox games (and how to spot them)

• Trusting the player's device. If money, items or damage are changed in a LocalScript, exploiters can change them too. Those changes belong in server Scripts.
• Unsafe RemoteEvents. A RemoteEvent like "GiveCoins(amount)" lets anyone give themselves anything. The server should decide amounts and check that the request makes sense.
• DataStores without error handling. Saves can fail. Calls should be wrapped in pcall, and the game should save when the server closes (game:BindToClose).
• Old APIs. Code written for older Roblox versions may still run but uses deprecated functions.
• UI that only fits one screen. Ask for sizes in Scale, and test on a phone.
• Inserted free models with hidden scripts. Check every script inside anything inserted from the Toolbox.

Whatever tool you use, the habit is the same: save a copy, make one change, press Play, check the Output.

A worked example

The BloxMaps team typed this into the Game Maker:

It built a game it named Candy Paradise: candy islands with a castle, an egg stand and a play area, plus the HUD, shop, pets, rebirth and saving of a pet simulator.

From there, the next steps are the human ones: open it in Studio, play it, change what you'd do differently, then publish and set up the passes (How to publish). For the hand-built route, read how to make a Roblox game and making a game without coding.
