flakesonnix/MeowV — reverse-engineered prompt

Build me a clean Rust prototype for a GTA style multiplayer server, but keep it totally safe and standalone, with no real GTA integration, no hooks, no reverse engineering, and no Rockstar services.

I want a workspace with a shared protocol, an async server, and a dummy client. The server should accept clients, do a protocol version handshake, let a client log in with a name, send a chat message, and receive simple fake entity position updates on a tick loop. Use readable newline JSON packets so it’s easy to inspect.

Add TOML config for both server and client, with sensible defaults and environment variable overrides. The client should also allow command line flags for name, config, and message. Include structured logs so I can see what’s happening.

Please include example config files, basic tests or checks where useful, and clear README instructions for running the server and client with normal Rust commands and with a Nix dev shell. Keep the legal boundary documented clearly before anything game specific is added.
