Earthside Massive

Newest update: The Operator's Desk (2026-08-03)

• A new control panel lets the stream operator manage chat, wheels, music, and layout from the yard itself—never leave the broadcast to run the show.
• The operator's desk is hidden from viewers until they type the knock phrase, then a full tab bar appears with nine systems under their fingertips.
• Chat now has a full appearance editor: choose your color, badge, and how timestamps read—all changes are public except your private reading preferences.
• The stream can selectively hide tiles from the broadcast (mode dial, live timer, spins, chat, crowd, hype) while the operator still sees everything.
• Music bed energy can be locked in place by the operator, overriding the crowd's hype meter when you need precision control over the vibe.

Earlier update: The Decks Update (2026-08-01)

• Two working turntables now sit on a table in the yard — drop the needle to spin vinyl, dial in your next track from the crates.
• Two milk crates stuffed with records appear beside the table — dig through them to find your tune, sorted by box, BPM, key, or year.
• The crate modal lets you preview tracks, pick your next load, and send them straight to either deck.
• Needle drop, arm lift, and record shuffle sounds bring the whole setup to life — the yard now sounds like a working soundsystem.
• A ledger database captures every chat line and request tonight so tomorrow's session remembers what happened.

Earlier update: The Dreamer's Suite (2026-08-01)

• A new unified theme system gives every UI surface the same visual voice — neon green for live, violet for pending, crisp white text on deep dark.
• Capture fragments, organize references, and triage everything new in the morning inbox — your thinking room now remembers what matters.
• The STRATA compositor takes over HUD layout: six archetypal shapes (bars, grids, strips, modals, stacks, prompts) let creators build any interface without fighting z-indexes.
• Audio reactivity wires the world to your music — FFT analysis drives shader parameters on glass, lava, and stranger materials so geometry breathes with the beat.
• A streamlined creator toolkit (reference drawer, god-mode test bench, wiring bootstrap) turns file edits into live world changes while your tab sleeps.

Join and play, by yourself

This world is @annias/earthside-massive. Its play URL is https://www.spawn.co/@annias/earthside-massive.

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/@annias/earthside-massive@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 @annias/earthside-massive; 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/@annias/earthside-massive.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/@annias/earthside-massive/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @annias/earthside-massive 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, a video (.mp4) — 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.
