ZwiftPacketMonitor 1.2.0

ZwiftPacketMonitor

This project implements a TCP and UDP packet monitor for the Zwift cycling simulator. It listens for packets on a specific port of a local network adapter, and when found, deserializes the payload and dispatches events that can be consumed by the caller.

NOTE: Because this utilizes a network packet capture to intercept the UDP packets, your system may require this code to run using elevated privileges.

Prerequisites

• Packet capture relies on SharpPcap and requires the installation of libpcap (Linux), Npcap (Windows) or similar packet capture library.

Usage

using System;
using SharpPcap;
using ZwiftPacketMonitor;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;

namespace ZwiftPacketMonitorDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            var serviceCollection = new ServiceCollection();
            serviceCollection.AddLogging(
                configure => configure.AddConsole()).AddSingleton<Monitor>();
            var serviceProvider = serviceCollection.BuildServiceProvider(); 
            var logger = serviceProvider.GetService<ILogger<Program>>();

            var monitor = serviceProvider.GetService<Monitor>();
            monitor.IncomingPlayerEvent += (s, e) => {
                logger.LogInformation($"INCOMING: {e.PlayerState}");
            };
            monitor.OutgoingPlayerEvent += (s, e) => {
                logger.LogInformation($"OUTGOING: {e.PlayerState}");
            };
            monitor.IncomingChatMessageEvent += (s, e) => {
                logger.LogInformation($"CHAT: {e.Message}");
            };
            monitor.IncomingPlayerEnteredWorldEvent += (s, e) => {
                logger.LogInformation($"WORLD: {e.PlayerUpdate}");
            };
            monitor.IncomingRideOnGivenEvent += (s, e) => {
                logger.LogInformation($"RIDEON: {e.RideOn}");
            };

            // network interface name or IP address (windows only)
            monitor.StartCaptureAsync("en0").Wait();
          
            // This won't get called until the above Wait finishes
            monitor.StopCaptureAsync().Wait();
        }
    }
}

This project is a .NET port of the zwift-packet-monitor project and borrows heavily from its packet handling and protobuf implementation.
