Your First World

Time to build something. By the end of this page you'll have a working multiplayer World that you can walk around in.

What's a World?​

A World is a playable multiplayer space on HELIX. It's the thing players see in the browser, click on, and join. A World is a special type of Package that bundles a map, scripts, and other Package dependencies into a complete experience. Right now, we're keeping it simple — one map, no scripts yet.

Two ways to create​

HELIX gives you two paths for building Worlds:

  • HELIX Studio — A customized Unreal Engine 5 Editor where you create Packages (maps, vehicles, wearables, Blueprints) and publish them to the Vault. This is the primary tool for serious content creation.
  • Build Mode — A real-time in-world editor you access by pressing N inside the HELIX client. Great for quick prototyping, placing objects, and testing ideas on the fly.

For this first World, we'll start with Build Mode to get you up and running fast. You'll use HELIX Studio later when you're ready to create custom assets and Packages.

Create the World​

  1. Open HELIX (the client) from the Launcher
  2. Go to the Worlds tab and click Create World
  3. Pick a map from the available options
  4. Hit Create

Your World is now live locally. You're standing in it. A local workspace folder has been created on disk to store your World's files.

Enter Build Mode​

Press N to enter Build Mode. This is your in-world editor — a real-time tool for placing and manipulating objects without leaving the game.

In Build Mode you can:

  • Place objects from the asset library (props, vehicles, structures, lights)
  • Move, rotate, and scale anything you've placed
  • Browse the Vault to add community Packages to your World
  • Test immediately — exit Build Mode and interact with everything you placed

Place some objects​

With Build Mode open:

  1. Browse the asset panel on the side
  2. Pick something fun — a chair, a car, a barrel, whatever catches your eye
  3. Click to place it in the World
  4. Use the gizmo handles to move it where you want
  5. Place a few more things. Make a scene. Go wild.

Press N again to exit Build Mode and walk around your creation as a player.

Save your World​

Click the Save button in Build Mode to keep your changes locally. Your saved World will appear under the Drafts filter in the Worlds tab.

That's it. You've made a World. It exists. You built it with your own hands.

What's next?​

A World with objects is cool, but a World with scripts is alive. Let's write your first script and make things happen.
