Pragmatic patterns for building multiplayer games: matchmaking, tick loops, realtime state, interest management, and validation. Includes starter code and architecture patterns for 10 game types (battle royale, arena, IO style, open world, party, physics 2D/3D, ranked, turn-based, idle) with actor topology, lifecycle diagrams, and netcode strategies. Covers server simulation fundamentals: fixed realtime loops vs. action-driven updates, physics engine selection (Rapier 2D/3D), and spatial...

Long-lived, stateful compute for AI agents, multiplayer apps, and workflow automation. Actors are persistent in-memory processes that maintain state across requests without database round trips, with automatic scaling from zero to millions of concurrent instances. Built-in realtime communication via WebSockets and events, durable queues for ordered message processing, and SQLite for structured data queries. State persists across restarts and crashes through Rivet Cloud or self-hosted...
