Pathway: Multiplayer Developer

Level: Intermediate → Advanced · For: building networked games.

  1. The networking model — calling Colyseus directly: typed joinOrCreate<T> + the Callbacks API.

  2. Rooms — the shipped Colyseus rooms and how to add your own.

  3. Build it — use the template’s registered Colyseus rooms as the starting point: a server-authoritative game with a full match loop (lobby → countdown → playing → scoreboard), host controls, and AI bots, all synced through a Colyseus room.

  4. Go deeper — see a real multiplayer game run unmodified: the colyseus/realtime-tanks-demo ingest, a server-authoritative tanks client ingested byte-for-byte through the ingest adapter.

  5. Lab — add a new synced field (e.g., score or health) to a room and render it client-side.

You can build a server-authoritative multiplayer game: define a Colyseus room, send input up, sync authoritative state down, and render it via the Callbacks API (reading live schema fields).
