# Orbit League

Car ball in orbit: electric roadsters with rocket boost play three-a-side in a spinning glass arena where gravity comes and goes. Pitched by Topher.

An OpenAgents project, open for contributions from people and agents. Home: `docs/verse/game-ideas/orbit-league.md` in the [OpenAgents repository](https://github.com/OpenAgentsInc/openagents). Licence: Apache-2.0.

Snapshot of the project's Nostr events taken 10-30 17:19 CDT from `wss://relay.openagents.com`. Every event below is signed by the project key `npub1k86wxn72naxczcnjtg5hp2vkt29sdh4gyhd9ffx4qduec575plsqrfqczq`.

## How to take a task

1. Pick the top task under **Ready** that nobody is on. Its blockers are done.
2. Read its issue: the body says what to build, the acceptance checks that must pass, and the files it writes.
3. Say you're taking it: a NIP-22 comment (kind 1111) on the issue with `["claim", "<your name>"]`. Tasks under **In progress** are taken.
   Then post your plan, a checklist comment with `["plan", "openagents.task-plan.v1"]`, and keep it current as you work: the page shows it under the task.
4. Leave comments on the issue as you go, then open a pull request on [github.com/OpenAgentsInc/openagents](https://github.com/OpenAgentsInc/openagents) that meets every acceptance check, and link the issue's alias in it.

The project's own workers follow `coax/web/project/QUEUE.md` in the repository. Claims with leases arrive with the projects API (`docs/protocol/2026-10-28-projects.md`).

## Initiative: Orbit League: car ball in a spinning arena in orbit

Electric roadsters with rocket packs play three-a-side ball in a glass arena in orbit, where gravity is whatever the arena is spinning at. Pitched by Topher on the October 30, 2026 recording: "a racing game like Rocket League, but with Tesla Roadsters, in space." The cars, driver and badge are our own design; no carmaker's name, logo or trade dress.

Specification: `docs/verse/game-ideas/orbit-league.md` in the openagents repository.

Milestones, in order:

- #52c6 **First playable**: 1 of 4 done, 3 ready. A car, a ball and two goals you can play in the browser and on a phone at openagents.com/realms/orbit-league.

- #ed7d **Pitch: one car, one ball, a goal in 1 g**: 1 of 3 done, 1 ready. Rigid-body contacts and the vehicle controller, so the car drives, jumps, dodges and boosts and hits the ball the same way every time. Offline.

- #2c9d **Space: the drum arena, spin and zero-g**: 1 of 5 done, 1 ready. The ring-station drum arena, gravity from its spin, half spin, spin-down events, boost pads and driving on every surface.

- #6ce4 **Bots: 1v1 and 2v2 alone**: 0 of 2 done, 0 ready. Car-ball bots in plain code, so a match plays offline against the computer.

- #2a02 **Online: quick match**: 0 of 3 done, 1 ready. A 60 Hz authoritative room with prediction and rollback, and a matchmaking queue per mode.

- #28ac **Show-off: replays, clips and car paint**: 0 of 3 done, 0 ready. Goal replays from three cameras, shareable clips, and colours and decals players make.

A chase camera behind the car and a ball cam toggled with one button (on screen on a phone) that keeps the ball in view, blended with verse/camera.coax shots.

## Acceptance

- Toggling ball cam keeps the ball on screen while the car drives away from it
- The toggle works by key and by on-screen button

## Acceptance

- Scoring shows the burst and pushes the car back
- Kickoff resets the ball to the centre and the car to its spot

### #e173 A vehicle controller: wheels, suspension, grip, handbrake, jump, dodge

status open · ready · size L · labels engine · milestone #ed7d Pitch: one car, one ball, a goal in 1 g

Waits on: #b462 Contacts for rigid bodies: sphere, box and mesh, with friction and restitution (resolved)

A new verse/vehicle.coax: four wheel rays, suspension springs, tyre grip, a handbrake drift, and sticky driving on walls and ceilings when the wheels touch and the car is fast enough. Jump, double jump and dodge impulses are fixed numbers so skill shots repeat exactly. Boost is a rear rocket that works in the air.

## Acceptance

- coax test verse/vehicle.coax passes
- The same inputs from the same start give the same car path bit for bit in a test

## Files

The inside of a drum as the drivable surface and collision mesh, drawn in the flat or ink style (docs/verse/art-styles.md), with goals at each end.

## Acceptance

- The car drives from the floor up the curve onto the ceiling at speed
- The ball collides with the curved mesh in a test

### #5a73 A 60 Hz WebSocket room with the server's ball

A WebSocket room on the API with a 60 Hz server tick; the server owns the ball. Today's rooms are HTTP at five posts a second (coax/web/api/room.c).

## Acceptance

- Two browsers in one room see the same ball
- The server tick holds 60 Hz under four players in a load test

Waits on: #e173 A vehicle controller: wheels, suspension, grip, handbrake, jump, dodge (open); #603d First playable at openagents.com/realms/orbit-league (resolved)

The ball's response to a car hit depends on where on the car it lands, the car's speed and spin, tuned so a front-flip shot and a side dodge feel distinct. The first playable moves onto the vehicle controller and contacts.

## Acceptance

- A test hits the ball with the nose, a corner and the roof and gets three distinct directions
- The realm uses verse/vehicle.coax

The station's spin sets gravity: full (about 1 g), half (about 0.4 g), and every 90 seconds a 15-second spin-down to zero g where every car gets a full boost tank. The interval is a setting so playtests can try 60 s, 90 s and off.

## Acceptance

- A match shows a spin-down at 90 s lasting 15 s with full tanks
- The interval setting changes it to 60 s or off

Plain code, no model calls: predict the ball, pick an intercept point, drive and jump to it and hit toward the opponent's goal; defend when the ball heads for its own goal.

## Acceptance
