# ENET Gaming Backend

A multiplayer game server written in C# using ENet for networking. 
Designed to support mutiple of my LÖVE2D game experiments at once.

## Technology Stack

- **Language**: C# (.NET)
- **Networking**: [ENet-CSharp](https://github.com/nxrighthere/ENet-CSharp) - reliable UDP multiplayer protocol
- **Deployment**: Docker + Nomad
- **Port**: `7777` (UDP, configurable)

## Quick Start

### Prerequisites

- .NET 8.0 or later
- ENet-CSharp (vendored or via NuGet)
- Docker (for containerization)

### Local Development

```bash
cd backend
dotnet build
dotnet run
```

The server will start and listen on `127.0.0.1:7777` by default.

### Testing Connection

With a LÖVE2D client configured to connect to `localhost:7777`:

```bash
love ../two_player_cleaning_game
```

## Configuration

Server behavior is controlled via environment variables:

```bash
ENET_HOST=0.0.0.0              # Bind address
ENET_PORT=7777                 # UDP port
```
