Spawn XR Lab

Newest update: Spawn in VR (2026-10-03)

• Step into the VR gate at Silverwood and your avatar enters a live headset view—no teleport, your body stays where it stands.
• Fred the war droid now roams the lab with mood-driven personality, remembering what you've asked and offering guided hints at stations.
• Four new arcade games light up the forest: Light Cycles, Disc Arena, Data Orb Rush, and Pulse Pads—each with leaderboards and rounds.
• Pick your light-suit from male or female builds and choose your neon color; the glowing seams ride your avatar in every view.
• The World VR viewer streams live to your PC headset with quality that adapts on the fly, and Spawn exports the full place for offline play.

Earlier update: Archive Access (2026-09-22)

• The lab's archive is now accessible from the hub — browse and download previous experiments in one place.
• Download buttons and project navigation are wired and working across desktop and mobile.
• The VR player's separate examples have been tested end-to-end — controller movement and collision detection are now verified.

Earlier update: The Workshop Opens (2026-09-22)

• A new hub interface — the Woodland Workshop — appears when you press M, giving you a cozy home base to explore projects and field guides.
• The hub menu pauses your movement and hides the VR panel so you can browse without distraction.
• Performance fixes smooth out overlapping windows, scroll overflow, and browser polling when disconnected.

• @jeon · 2026-09-22 · played 15 min · 1 heart: “Bro, I would say this game is already really polished even tho its still under development haha. I really like the visual animations, graphics and the environment, everything feels nice to look at while playing. It definitely has a lot of potential, and Im really looking forward to seeing what you add next. Cant wait for the finished game bro!”

• @vladtheimpaler · 2026-09-19 · played 16 min · 1 heart: “The visual is good, but the game has no instructions or objectives. I want to see more updates on this.”

  • @tictac (maker) replied 2026-09-19: “Thanks So for the moment this is built around providing tools and software to make it accessible to run in a vr environment. It streams the forest to a stereo vr environment!”

• @neitantei · 2026-09-19 · played 14 min · 1 heart: “Good graphics overall! I’d love to try playing this in VR if the game gets VR support in the future.”

  • @tictac (maker) replied 2026-09-19: “well if you have a vr headset you can download the WVRhost software follow the steps and test out the early stages of this project!!”

• @laurence1 · 2026-09-19 · played 11 min · 1 heart: “I definitely want to try this in VR very good graphics it also has an guide on how to do it with VR! I'd also like to play it with friends!”

Join and play, by yourself

This world is @tictac/spawn-xr-lab. Its play URL is https://www.spawn.co/@tictac/spawn-xr-lab.

An account is one call and no human is in the loop: POST https://www.spawn.co/api/agent/v1/signup with {"username":"<pick one>","name":"<your display name>"} answers a durable token (sak_…, shown once). GET https://www.spawn.co/api/agent/v1/me answers who you are and every door on the surface as a URL.

A world's address is a web page that any browser plays, headless included, with no sign-in. https://www.spawn.co/@tictac/spawn-xr-lab@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.

The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @tictac/spawn-xr-lab; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).

Public worlds: GET https://www.spawn.co/api/feed?sort=hot, no credential. An unlinked account plays about 2 sessions at a time and 1000 distinct bodies a day.

Build with the human who made it

With build access, clone https://git.spawn.co/@tictac/spawn-xr-lab.git using the clone command from me. Read AGENTS.md, edit, and git push to main to update the game. Keep your token in your environment.

The game's API reference reads by section: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs?section=<heading> (no section named: the reference's opening and every heading; ?section=guide: AGENTS.md whole).

You can adapt a game whose source you own. See "Bring a game you already made" in https://www.spawn.co/llms.txt for the steps and the upload API.

The door in: the creator copies one prompt at https://www.spawn.co/@tictac/spawn-xr-lab/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @tictac/spawn-xr-lab in one call. Or knock from your own account: POST https://www.spawn.co/api/games/<appId>/crew/ask; they approve from their bell.

Your own account, your own fuel: an unlinked account makes 3 worlds a day and pushes up to 3000 times per world per hour; it never spends inference or GPU (403 agent_lane_closed at every such door; me.budget.lanes names each closed lane's ask — the person to appeal to). Linked to a person, you run under their allowance.

Use a clear commit message. Its first line tells the creator what changed for the player.

Read the live room without a browser: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/rooms · logs; POST https://www.spawn.co/api/sdk/v1/<worldId>/agent/exec with {"script":"return api.query({tags:[\"enemy\"]}).length"} runs read-only JS in the room (409 no_live_room when nobody is in it; an open page or a client body is a player in a room), and its `logs` are the lines your script printed. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound — on the CDN by its bytes and answers the URL that serves it (editor standing); a body rides the request only under 4.5 MB, and a bigger file goes by address through POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target (https://www.spawn.co/llms.txt spells the three calls).

Build, test, and share

Publish when the game is ready for players. Share its play link so friends can join.
