# Hearts of Iron IV ELO Discord Bot

## Project Overview

A sophisticated Discord bot designed specifically for Hearts of Iron IV multiplayer communities, featuring a complete ELO rating system similar to chess rankings. This bot helps organize competitive matches, track player performance, and maintain fair gameplay through advanced statistical analysis.

## 🎮 Key Features

### ELO Rating System
- **Dual Rating Modes**: Separate ELO ratings for Standard and Competitive gameplay
- **Chess-like Algorithm**: Uses proven ELO formula with HOI4-specific modifications
- **T-Level System**: Country tier-based multipliers (T1: 0.8x, T2: 1.0x, T3: 1.2x points)
- **Draw Support**: Intelligent draw handling with ELO adjustments based on team strength differences
- **Starting Rating**: 800 ELO for all new players

### Game Management
- **Match Creation**: `/hoi4create` - Set up Standard or Competitive games
- **Player Setup**: `/hoi4setup` - Add players with team assignments and T-levels
- **Game Completion**: `/hoi4end` - Process results and calculate ELO changes automatically
- **Live Tracking**: Real-time game status and player management

### Statistics & Analytics
- **Player Profiles**: Comprehensive stats with ELO rankings and percentiles
- **Win/Draw/Loss Records**: Complete match history tracking
- **Leaderboards**: Ranked player lists with detailed performance metrics
- **Match History**: Searchable game archive with filtering options

### Advanced Features
- **Hybrid Commands**: All commands work as both slash (/) and text (!) commands
- **Permission System**: Owner-only administrative commands
- **Error Handling**: Robust error management with detailed logging
- **Database Integration**: MySQL support with automatic table creation

## 🛠 Technical Implementation

### Architecture
- **Framework**: Discord.py 2.3.2 with hybrid command system
- **Database**: MySQL with aiomysql for async operations
- **Deployment**: Docker containerization with Coolify support
- **Environment**: Python 3.10+ with comprehensive dependency management

### Database Schema
```sql
-- Players table with dual ELO ratings
players (discord_id, username, standard_elo, competitive_elo, timestamps)

-- Games with JSON player data and match metadata
games (game_name, game_type, status, players, winner_team, timestamps)

-- Detailed match results for statistical analysis
game_results (game_id, discord_id, team_info, elo_changes, result_type)
```

### ELO Calculation Algorithm
```python
# Standard ELO formula with HOI4 modifications
expected_score = 1 / (1 + 10^((opponent_avg - player_elo) / 400))
elo_change = K_FACTOR * (actual_score - expected_score) * t_level_multiplier

# Result scoring: Win=1.0, Draw=0.5, Loss=0.0
# K-Factor: 32 (standard competitive value)
```

## 🚀 Deployment & Infrastructure

### Docker Configuration
- **Base Image**: Python 3.10-slim for optimal performance
- **Dependencies**: Automated installation with requirements.txt
- **Environment Variables**: Secure configuration through Coolify
- **Health Checks**: Built-in monitoring and error reporting

### Coolify Integration
- **One-Click Deployment**: Seamless integration with Coolify platform
