What you need to start building in Roblox

You can start creating in Roblox with nothing but a free account and a computer that runs Windows, Mac, or Linux. Roblox Studio — the tool where you actually build games — is free to read from the official Roblox website. You do not need to buy anything upfront, and you do not need special hardware beyond what most people already have.

The barrier is not cost or equipment. It is learning the workflow: how to place objects in a 3D space, connect them with code, test what you built, and publish it so other people can play. Roblox Studio handles all of that in one process, which is why most people start there instead of learning a separate engine like Unity or Unreal.

Key Takeaways

  • Roblox Studio is free and runs on Windows, Mac, and Linux — read it from the official Roblox website after creating a free account.
  • You build games by placing parts (blocks, shapes, terrain) in a 3D world, then connect them with Lua code to make them do things.
  • Testing happens inside Studio before you publish — you can play your own game to find problems before other people see it.
  • Publishing is free, but earning money from your game requires you to convert in-game currency to Robux, which Roblox takes a cut from.
  • Most beginner games start with a straightforward idea like a platformer, obby (obstacle course), or simulator rather than trying to build a full MMO.

Installing Roblox Studio and setting up your first project

Go to create.roblox.com and sign in with your Roblox account. If you do not have one, create it at roblox.com — it takes two minutes. On the create page, click the blue "Create" button, then read Roblox Studio for your operating system. The installer is about 500 MB and takes a few minutes.

Once Studio opens, you will see a blank baseplate — a flat gray square where your game world sits. This is your starting point. You can delete it, keep it, or build on top of it. Most people keep it because it gives players something solid to stand on. The left panel shows your game's structure (called the Explorer), the center is your 3D view, and the right panel holds properties you can change for any object you select.

Before you start building, go to File > Save As and give your game a name. Studio saves your work locally on your computer, not to the cloud, so you are responsible for not losing it. Save often.

Building your first objects and understanding parts

Everything in Roblox is made of parts — blocks, spheres, cylinders, and wedges that you stack and arrange to create the world. To add a part, go to the Insert menu at the top, click Part, and choose a shape. A new part appears in the center of your view. You can move it by dragging the arrows that appear, rotate it, or resize it by dragging the corners.

Parts have properties you change on the right side of the screen. You can change the color, material (plastic, wood, metal, neon), whether it is solid or can be walked through, and whether it moves or stays still. A part that does not move is called anchored — most scenery is anchored so the wind or gravity does not knock it over. Parts that move are unanchored and fall down unless something holds them up.

Start by building something straightforward: a platform, a ramp, or a small room. Place a few parts, change their colors, and get used to moving things around. This teaches you how the 3D space works before you add code.

Adding code with Lua to make things happen

Roblox uses Lua, a programming language that is simpler than Python or JavaScript. You do not need to know Lua before you start — you learn it by writing small pieces and testing them. Every part can have a script attached to it, and that script tells the part what to do.

To add a script, right-click a part in the Explorer panel on the left, click Insert Object, then Script. A code editor opens with a blank script. Type this straightforward example:

local part = script.Parent part.BrickColor = BrickColor.new("Bright red") wait(2) part.BrickColor = BrickColor.new("Bright blue")

This script makes the part turn red, wait two seconds, then turn blue. Click the green play button at the top to test it. Your part changes color. That is code working. From there, you can make parts move, detect when a player touches them, award points, or trigger events.

Most beginners copy scripts from the Roblox Developer Hub (developer.roblox.com) rather than writing from scratch. The Hub has hundreds of examples: how to make a door open when clicked, how to award currency, how to detect if a player jumped. Copy the code, paste it into your script, change the numbers to fit your game, and test.

Testing your game before publishing

Click the green play button in Studio to test your game as a player would experience it. You spawn in the world, can move around with WASD, jump with space, and interact with anything you coded. If something does not work the way you expected, stop the test, fix the code or the parts, and test again.

Testing is the fastest way to learn. You will find bugs (things that do not work right), confusing controls, or parts that are in the wrong place. Fix them before you publish. A game that works badly will lose players quickly, and you cannot easily change it once it is live.

Use the Output window at the bottom of Studio to see error messages. If your code breaks, the Output window tells you what went wrong and which line caused it. This is your main tool for debugging.

Publishing your game so others can play it

When your game is ready, go to File > Publish to Roblox. You will be asked to give your game a name, description, and choose whether it is public (anyone can find it) or private (only people with the link can play). Roblox reviews your game for content violations — no hate speech, no stolen assets, no real-world money trades outside the Roblox system. Most games are approved within a few hours.

Once published, your game gets a page on Roblox where people can see screenshots, the description, and a play button. You can update your game anytime by publishing again — the changes go live when ready.

If you want to earn Robux (Roblox's currency) from your game, you need to be at least 13 years old and have a Premium membership. You can add in-game purchases — cosmetics, game passes, or developer products — that players buy with Robux. Roblox takes 30 percent of what players spend, and you keep 70 percent. You can convert that to real money once you have earned at least 100,000 Robux.

Common beginner mistakes and how to avoid them

The biggest mistake is trying to build too much at once. New creators often start with ideas like "a massive open world with 50 different games inside it." That takes months. Start with one small idea: a single obby (obstacle course), a tycoon game where players build something, or a straightforward simulator. Finish it, publish it, and learn from how people play it.

The second mistake is not testing enough. You think your game works because it worked when you tested it once. But players will find ways to break it that you did not think of. Test repeatedly, ask friends to play it, and watch what they do wrong.

The third mistake is copying code without understanding it. If you paste a script and it does not work, you cannot fix it because you do not know what it does. Read the code, change one small thing, test it, and see what changed. That teaches you faster than copying blindly.

Frequently Asked Questions

Do I need to pay for Roblox Studio?

No. Roblox Studio is completely free. You do not pay to read it, use it, or publish games. You only pay if you want to buy Robux (the in-game currency) to spend on cosmetics or game passes in other people's games.

Can I use assets or code from other Roblox games?

No. Copying code, models, or scripts from published games violates Roblox's terms. You can learn from them and write your own version, but you cannot copy and paste. The Roblox Developer Hub has free, legal examples you can use and modify.

How long does it take to make a straightforward game?

A very straightforward game — a single obby or a basic simulator — can take a few hours to a few days if you follow tutorials. A more polished game with multiple features takes weeks or months. Start small and add features as you learn.

What computer do I need to run Roblox Studio?

Studio runs on Windows, Mac, and Linux. You do not need a gaming PC. A laptop with 4 GB of RAM and a basic processor can run Studio and build small to medium games. Larger, more complex games benefit from more RAM and a better GPU, but you can start on almost any computer.

Can I make money from my game?

Yes, but only if you are at least 13 years old and have a Premium membership. You add game passes or in-game purchases that players buy with Robux. Roblox takes 30 percent, and you keep 70 percent. You can convert Robux to real money once you have earned at least 100,000 Robux.
