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

Resources

• Learn X In Y C#

Next Steps

• Set up C# project structure
• Integrate ENet-CSharp dependency
• Implement basic server startup
• Define message protocol
• Create player session management
• Build Docker image
• Test Nomad deployment
• Implement game state synchronization
