How to make a Roblox game with AI
Start with an idea, build and refine it in chat, then playtest and publish in Roblox Studio. You can begin without writing code.
Your first Roblox game needs a place to begin, something for the player to do and a reason to try again. With AI, you can start by describing those things in plain words. PromptBlox builds a starting scene and gameplay scripts from your description in the browser, and you shape both through chat as the project develops.
This tutorial takes a small game from its first prompt through refinement, export and a Studio playtest. Each step helps you turn an idea into something you can check with an avatar and eventually share with players.
If you are new to game making, write the idea in one sentence first: “Players do an activity in a place to reach a goal.” For example, “Players collect firewood around a mountain campsite and bring it to the campfire.” That gives you a setting, an activity and a finish, which is enough for a first build. Saved projects stay in your Library, and History shows their earlier saved versions.
Make your first game, step by step
Describe a small game you can test
Open Create and explain the setting, what players do, and what happens when they succeed or fail. Choose an available build level, check your account usage and send the prompt to start.
Begin with one activity and a clear goal. For example, a collecting game needs somewhere to find objects, somewhere to bring them and a reason to take another trip. Here is an example prompt you can adapt in Create:
Make a small mountain campsite where players collect firewood from marked spots and bring it to the campfire. Show how much wood they carry and count each delivery. After three deliveries, celebrate with a brighter campfire and offer a restart. Use warm lanterns, pine trees and broad paths. Keep the campsite compact and make the next destination easy to find.
This is a starting idea for a build. Check the resulting scene and gameplay as you work through the steps below. The first steps work in a computer, tablet or phone browser; if you are starting on a phone, see how to make a Roblox game on mobile.
Follow the concept and build activity
PromptBlox generates one concept image as a visual reference, then continues building. The chat opens into a workspace where you can follow activity and review the scene as updates arrive.
Look for the main places in your prompt: the starting area, the activity and the destination. In the campsite example, a new player should be able to spot both the firewood and the campfire.
You can send notes in chat while the build runs. When chat is available for a change request, keep it specific and check the progress updates to see when that change reaches the build.
Refine the existing game in chat
Open the saved game and ask for a focused improvement. Name the area or behavior you want to change and explain what should stay the same.
For the campsite, a visual refinement might be:
Make the route from the starting tent to the campfire clearer. Widen that path and add small lanterns along it. Keep the trees, collection spots and mountain setting.
Once you have played the game, bring observations back to the same chat. For example: “Delivering wood leaves the carry counter full. Clear the carried wood after a delivery and increase the delivery count once.”
Download the place and open it in Studio
When the version you want to test is ready, open Export and download the .rbxlx place file. Open the file in Roblox Studio to access the saved scene and its scripts.
If you need Studio, follow Roblox’s setup instructions for Windows or Mac. A .rbxlx is Roblox’s XML place format; its place-file guide explains local copies. Keep track of which version you download so your playtest feedback refers to the right build.
Play the complete game loop
In Studio, choose Test and press Play to enter with an avatar. Start at spawn, complete the activity, check the result and try again. Test failures, restarts and the devices you intend to support.
The browser preview helps you review the world’s appearance and layout. Studio is where you check movement, collisions and scripts. For a multiplayer game, also test with multiple players. Roblox’s testing-mode documentation explains these options. Use the checklist below to turn what you observe into the next set of edits.
Publish and choose your audience
Stop the playtest and use File → Publish to Roblox in Studio. Add a name, description and supported devices. Choose the intended audience in Creator Dashboard when the game is ready.
New experiences begin private. Before inviting a wider audience, follow Roblox’s current publishing instructions and requirements for your account. When you improve the game later, save and publish the updated version.
What to check before you add more
- A clear start. Spawn into a safe space with a visible goal. Ask a new player to find the first activity without your help.
- A complete loop. Perform the main activity, receive its result and repeat it. Check that counters, rewards and carried objects change as intended.
- A way to recover. Try falling, resetting your character or failing a challenge. Check where you return and which progress is kept.
- Controls that fit the players. Check movement, camera clearance and readable instructions on your intended devices. Test individual progress with more than one player when the game supports multiplayer.
- A useful ending. Make success visible and give the player a next step, such as restarting or taking another delivery.
You can also start directly in Studio
If you prefer to build by hand, open Studio and choose a starting template. Baseplate gives you a small foundation to build on. Add the world’s objects, use scripts for the interactions you want, and playtest the same small loop as you go. Roblox’s guide to creating games and places explains the starting templates. If you want help while you build by hand, see this overview of AI tools inside Roblox Studio.
You can also use Studio to customize a PromptBlox export. The AI game generator guide has more example prompts, and the obby walkthrough goes deeper on obstacle courses.
Questions about your first Roblox game
For current PromptBlox allowances and plan options, see plans and usage.
Can I make a Roblox game without knowing how to code?
You can start with a plain-language prompt and use chat to request scene and gameplay changes in PromptBlox. It can author Luau scripts for your game. Playtesting and refining the result remain part of making a game; learning Studio and Luau gives you more control over later edits.
What is a good first Roblox game?
Choose a small idea with a complete loop: a short obstacle course, a collection-and-return activity or a simple delivery route. Define where the player starts, what they do, how they succeed and how they try again. Expand after that first loop plays well.
Do I need to install Roblox Studio before I start?
You can describe, generate, review and refine the game in PromptBlox’s browser interface before installing Studio. This guide uses Studio for avatar playtesting, detailed editing and publishing the exported place to Roblox.
How long does making a game take?
The time depends on the build level, the size of the game and the changes it needs. Allow time for your own playtests and improvements as well as generation. A compact first version is easier to test completely before you add more areas or systems.
What does it cost to get started?
You can start free with Light builds and a small weekly allowance, and Roblox Studio is free. Paid plans add more weekly usage, and Pro and higher plans unlock Medium, High or Ultra builds, depending on the plan. Builds and later edits both draw on your allowance, and larger work uses more of it.
Can I keep editing after I export?
Yes. You can continue refining the saved project in PromptBlox or edit the downloaded place in Studio. Keep track of which version contains your latest changes, and playtest that version before publishing.
