Co-op multiplayer sandbox with authoritative server
A small survival sandbox where four players share one world, the server decides what is true, and the client only predicts.
What it is
Built in Godot 4 with a dedicated headless server. Player input is predicted locally and reconciled against the server's authoritative state, so movement feels immediate and cheating is not a client-side decision. Nakama provides accounts, matchmaking and persistence. A frame-time budget is enforced in CI.
What the build consists of
- 01Headless authoritative server with client-side prediction and reconciliation
- 02Interest management so each client only receives what it can see
- 03Nakama for authentication, matchmaking, parties and saved worlds
- 04Deterministic world generation from a seed
- 05Automated performance test that fails the build past 16.6 ms per frame
- 06Exports for Windows, macOS, Linux and web
What you see in a demo
Four clients on a simulated 120 ms connection, one of them attempting to teleport, and the server quietly putting them back.
