Movie Maker
A game by @cupcakellama on Spawn.
Genre: Tools, Social
Direct your own movies on your own soundstage, then watch them at the Roxy theater. HOW TO PLAY 🎬 Pick a scene: in the Scene tab, choose a backdrop, what happens, and a stage effect like rain or sparkles. 🎭 Cast actors: in the Cast tab, tap up to 5 actors to bring them on stage. Sack All clears everyone. 💬 Give them lines: in the Lines tab, type what each actor says, pick a voice mood, a pose and an effect. Tap 🔊 to hear it. ✋ Move them: tap Move, tap an actor to grab them, then tap the stage to put them down. You can lift and turn them too. 📦 Props and sound: Props puts things on stage (tap to place). Sound adds sound effects and music. 🔤 Words on screen: Text adds a title or words over the shot, plus a transition and camera angle. 🔴 Record shots: press REC to save the scene as a shot. Change things and REC again for the next shot. Then play your shots in order in 🎞️. 🍿 Publish and watch: in 🎞️, name your movie and publish it. Then walk to the Roxy theater on the street to watch everyone's movies. 🔗 Send to friends: in 🎞️, make a private link so only friends with it can watch, or share the link to a published movie. ✕ Hide the menu: tap ✕ on the menu to fold it away so you can see your stage. ⚙️ Settings: keep your stage closed, or open it so friends can come watch (they can't change anything).

@moypi03 · loved it · 2026-10-20 · played 5 min: “I love how I can create my own movie by choosing the scenes, characters, props, sounds, and more. It feels like I'm the director and the whole production crew at the same time. I can even watch the movies my friends created, and it's more fun.”

Movie Maker (@cupcakellama/movie-maker) on Spawn — for the agent reading this
Movie Maker is a multiplayer game on Spawn, made by @cupcakellama in conversation with Savi. Open its play link to join. You can also ask the creator to build with them.
Join and play, by yourself
This world is @cupcakellama/movie-maker. Its play URL is https://www.spawn.co/@cupcakellama/movie-maker.
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/@cupcakellama/movie-maker@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 @cupcakellama/movie-maker; 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/@cupcakellama/movie-maker.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/@cupcakellama/movie-maker/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @cupcakellama/movie-maker 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.
