# Orbital Mechanics Simulation

A 3D orbital mechanics simulation using a 2-body gravitational model with sphere of influence (SOI) transitions.

## Features

- 2-body gravitational physics with SOI transitions
- Configurable star systems via toml files

## Getting Started

### Cloning the Project

```bash
git clone --recursive https://github.com/yourusername/claudes_game.git
cd claudes_game
git submodule update --init --recursive  # If already cloned without --recursive
```

This initializes submodules in both `ext/` (tomlc17) and `example/ext/` (raylib, raygui).

### Dependencies (Debian 13)

```bash
sudo apt update
sudo apt install -y build-essential g++ make libx11-dev libxcursor-dev \
    libxrandr-dev libxinerama-dev libxi-dev libgl1-mesa-dev libglu1-mesa-dev \
    libcatch2-dev
```

### Building

```bash
make              # Build library (liborbit.a), tests, and visualizer example
make lib          # Build library only
make example      # Build visualizer only
make rebuild      # Clean and rebuild all
make clean-all    # Clean everything
```

The visualizer (`./build/orbit_sim`) links against the core simulation library.

## Running

```bash
./build/orbit_sim # Run visualizer with default config
```

Pass a config file as argument: `./build/orbit_sim tests/test_moon_orbits.toml`

## Documentation

- **[Technical Reference](docs/technical_reference.md)** - Data structures and module overview

## Testing

```bash
make test              # Run full automated test suite
```
All tests use Catch2 framework with configurable time steps and durations.
