中文 README

A cross-platform Minecraft P2P online multi-player library in C#, developed using high-performance sockets for excellent forwarding performance, with P2P powered by the Zerotier SDK.

Proudly powered by another of our open-source projects: Hive.Framework

Quick Start!

We are using the MSDI(Microsoft.Extensions.DependencyInjection) as our DI container. The best practice is to use .NET Generic Host for you program.

First, add the following method for the Server Config. ConnectXServerIp will be the Backend address for the ConnectX.Server.

private static IClientSettingProvider GetConnectXSettings()
{
    var serverIp = IPAddress.None;

    try
    {
        var ips = Dns.GetHostAddresses(ConnectXServerIp);
        var ipv4Addresses = ips
            .Where(ip => ip.AddressFamily == AddressFamily.InterNetwork)
            .Where(ip => !ip.IsLocalIpAddress())
            .ToArray();

        if (ipv4Addresses.Length > 0)
            serverIp = ipv4Addresses[0];
    }
    catch (Exception ex)
    {
        Log.Logger.Error(ex, "Failed to resolve ConnectX server IP.");
    }

    return new DefaultClientSettingProvider
    {
        ServerAddress = serverIp,
        ServerPort = ConnectXServerPort,
        JoinP2PNetwork = true
    };
}

Then, just add one more line to complete the setup!

private static void ConfigureServices(IServiceCollection services)
{
    // ...
+   services.UseConnectX(GetConnectXSettings);
    // ...
}

How to use?

Inject IServerLinkHolder and Client into the VM where you want to manage the room instances.

Connect to the server

await _serverLinkHolder.ConnectAsync(CancellationToken.None);

Perform room actions

Important

Please make sure that before you perform any room operations, you need to make sure you already connected to the ConnectX server!

await TaskHelper.WaitUntilAsync(() => _serverLinkHolder is { IsConnected: true, IsSignedIn: true });

var message = new CreateGroup
{
    UserId = _serverLinkHolder.UserId,
    RoomName = createRoomRecord.RoomName,
    RoomDescription = createRoomRecord.RoomDescription,
    RoomPassword = createRoomRecord.RoomPassword,
    IsPrivate = createRoomRecord.IsPrivateRoom,
    MaxUserCount = 3
};

var (groupInfo, status, err) = await _multiPlayerClient.CreateGroupAsync(message, CancellationToken.None);

if (groupInfo == null || status != GroupCreationStatus.Succeeded || !string.IsNullOrEmpty(err))
{
    // Error process
    return;
}

_multiPlayerClient.OnGroupStateChanged += MultiPlayerClientOnGroupStateChanged;

// Other actions
