DeltaMUD

DeltaMUD is a text-based multiplayer RPG (MUD) virtual world engine derived from CircleMUD 3.0, featuring a modern Rust reimplementation alongside the original C reference.

Project Structure

• rust-mud/: Modern Rust engine (~75k lines, ~83 modules). High performance, memory-safe, single-owner architecture bootable against original world files with verified behavioral parity.
• src/: Legacy C source codebase (historical reference).
• lib/: World files, zones, rooms, mobiles, objects, and text configurations.
• deltamud_schema.sql: MySQL / MariaDB database schema for persistence.

Quickstart (Rust Engine)

Prerequisites

• Rust 1.75+ (or latest stable)
• MySQL / MariaDB (optional, for persistent player data)
