MUD AI Player

An autonomous AI player for MUD (Multi-User Dungeon) text-based games.

Features

• 🤖 Autonomous Gameplay: Simulates a human player from character creation to endgame
• 🗺️ Auto-Mapping: Builds a complete map of the MUD world with hybrid storage (SQLite + Memvid)
• ⚔️ Combat AI: Intelligent combat decisions, target selection, and survival tactics
• 📜 Quest System: Automatically detects, plans, and completes quests
• 🔍 Semantic Search: Find locations using natural language queries
• 📊 Progression Optimizer: Finds optimal grinding spots and equipment upgrades
• 🧠 LLM Integration: Context-aware responses to players using local LLMs (Ollama)
• 🌐 Web Dashboard: Real-time monitoring dashboard with WebSocket updates
• 👤 Human Behavior: Simulates realistic reaction times and behavior patterns

Architecture

The application is built with a modular architecture:

• Core: Telnet client, ANSI parser, text parser, game state
• Modules:
  • Character Creator: Stats rolling, class/race selection
  • Auto-Mapper: World mapping with hybrid storage (SQLite + Memvid)
  • Decision Engine: AI decision-making, combat AI, goal management
  • Quest System: Quest detection, planning, execution
  • Progression Optimizer: Grinding optimization, equipment analysis
  • LLM Integration: Ollama/OpenAI-compatible LLM client with memory
  • Web Dashboard: FastAPI-based monitoring with WebSocket support

Installation

Using Poetry (Recommended)

# Install Poetry if not already installed
pip install poetry

# Install dependencies
poetry install

# Activate virtual environment
poetry shell

Using pip

# Create virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements.txt

Configuration

1. Copy the example configuration:

   cp examples/config.example.yaml config.yaml
   

2. Edit config.yaml with your MUD server details:

   mud:
     host: "your-mud-server.com"
     port: 4000
     username: "your_username"
     password: "your_password"
   

Usage

# Run the AI player
python -m src.main

# Run with custom config
python -m src.main --config custom_config.yaml

# Run tests
pytest tests/ -v

# Run with coverage
pytest --cov=src --cov-report=html
