2017 DevFestMN Martin Omander
summary
A multiplayer web game for family game night gets built with JavaScript, Angular + AngularFire and Firebase hosting and database, syncing game state as a real-time JSON tree over WebSockets and yielding about 86 ms roundtrip. Smooth 60 fps visuals come from local simulation with occasional authoritative updates and requestAnimationFrame decoupling, device variability is handled by separating simulation and rendering, and usability fixes (visible fuel meters) make the prototype playable with mixed ages and devices.
