 # Unreal3Arena
 
+A Quake 3 Arena clone built in Unreal Engine 5 with procedurally generated assets and CI/CD pipeline.
+
+## Overview
+
+This project recreates the classic Quake 3 Arena experience in Unreal Engine 5, featuring:
+- **Procedural Level Generation**: Levels generated from Python code for testability
+- **Bot AI**: Crash bot implementation with combat and navigation logic
+- **Deathmatch Game Mode**: Classic Q3A deathmatch rules
+- **CI/CD Pipeline**: Automated testing and validation
+
+## Features
+
+### Game Systems
+- **Quake 3 Arena Game Mode** (`Plugins/GameFeatures/Quake3Arena`)
+  - Deathmatch with frag limit and time limit
+  - Bot spawning and management
+  - Respawn system
+  
+- **Crash Bot AI**
+  - State-based behavior (Combat, Roaming, Seeking Items)
+  - Navigation using UE5's Navigation System
+  - Configurable skill levels
+
+### Procedural Generation
+- **Arena Level Generator** (`Tools/ProceduralGeneration`)
+  - Code-based geometry generation
+  - Exports to JSON format
+  - Unit tested with pytest
+  - Inspired by Q3DM17 "The Longest Yard"
+
+### CI/CD
+- **Automated Testing**: Python unit tests for procedural generators
+- **Project Validation**: JSON validation, structure checks
+- **Artifact Generation**: Automated arena geometry generation
+
+## Getting Started
+
+### Prerequisites
+- Unreal Engine 5.7
+- Python 3.11+ (for procedural generation)
+- Git
+
+### Installation
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/johndoe6345789/Unreal3Arena.git
+   cd Unreal3Arena
+   ```
+
+2. Install Python dependencies:
+   ```bash
+   cd Tools/ProceduralGeneration
+   pip install -r requirements.txt
+   ```
+
+3. Generate arena geometry:
+   ```bash
+   python arena_generator.py

+# Procedural Arena Generator
+
+This directory contains Python scripts for procedurally generating Quake 3 Arena style levels and assets.
+
+## Features
+
+- **Code-based generation**: All assets are generated from code, making them testable
+- **Parametric design**: Easy to adjust arena size, platform placement, etc.
+- **Unit tested**: Full test coverage for geometry generation
+- **JSON export**: Geometry exported to JSON for import into Unreal Engine
+
+## Installation
+
+```bash
+pip install -r requirements.txt
+```
+
+## Usage
+
+### Generate an arena:
+
+```bash
+python arena_generator.py
+```
+
+This will create `arena_geometry.json` with the complete arena geometry.
+
+### Run tests:
+
+```bash
+python -m pytest test_arena_generator.py -v
+```
+
+Or using unittest:
+
+```bash
+python test_arena_generator.py
+```
+
+## Generated Geometry
+
+The generator creates:
+
+1. **Main Floor**: The base arena floor
+2. **Walls**: Perimeter walls around the arena
+3. **Platforms**: Floating platforms (similar to Q3DM17 "The Longest Yard")
+4. **Jump Pads**: Launch pad positions (geometry for placement)
+
+## Integration with Unreal Engine
+
+The JSON output can be imported into Unreal Engine using:
+1. Blueprint scripts that read the JSON
+2. Python scripts in UE5 Editor
+3. Custom C++ importers using GeometryScripting API
+
+## Future Enhancements
+
+- CADQuery integration for more complex geometry
+- Weapon pickup generation
+- Health/Armor pack generation
+- Texture coordinate optimization
+- LOD generation
+- Collision mesh generation
