Simple WebSocket Game Server

A pure‑Python WebSocket server for a top‑down multiplayer game prototype (think MooMoo.io–style).
It handles the entire handshake and framing layer itself (no websockets or aiohttp), packs packets with MessagePack, maintains a tiny game world, and streams real‑time player / object updates to connected clients.

Status: experimental / proof‑of‑concept
The code is intentionally minimal and not production‑ready. Use it to learn how WebSocket framing works, how to structure a lightweight game loop, or as a starting point for your own hobby project.

✨ Features

Area	Details
WebSocket handshake	Custom implementation — no third‑party WebSocket library required.
Binary framing	Supports OPCODE_TEXT, OPCODE_BINARY, PING, PONG, and CLOSE.
Message format	Uses msgpack for compact packets.
Game objects	Players (PlayerObject) and scenery (GameObject) with IDs, position, scale, etc.
Minimal game loop	Position updates, simple 8‑direction movement, basic attack flag.
Broadcast helpers	Framework in place (GameWorldManager) for global messages / resource grants.
Threaded I/O	Separate threads per client for receive & game‑loop ticks.

📦 Requirements

• Python 3.8 +
• msgpack   pip install msgpack

Note
The script imports a local module Net.PacketCodes that maps packet IDs ↔ codes.
Provide your own or stub it out if you only want to test the transport layer.

🚀 Quick start

git clone https://github.com/<your‑user>/<your‑repo>.git
cd <your‑repo>

# (optional) create a venv
python -m venv venv
source venv/bin/activate   # Windows: venv\Scripts\activate

pip install msgpack

python server.py           # or whatever filename you choose
By default the server binds to 0.0.0.0:3000:
