Technology Stack

Language: C# (.NET)
Networking: 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

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:

love ../two_player_cleaning_game

Configuration

Server behavior is controlled via environment variables:

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