Sample Code

Simple Console Chat Program

IPAddress ip;      // Server IP address
ushort port;       // Server port number
string playerName; // Player name (Replace with SessionToken if required for online mode login)

MinecraftClient client = await ClientBuilder.FromServerListPingAsync(ip, port);
ChatType[] chatTypes = null;

// Listen for received packets
client.PacketReceived += (m, args) =>
{
    if (!m.Joined)
        return;

    // Output chat messages received from the server to the console
    if (CompatibleReader.TryReadServerChatMessage(args.Packet, chatTypes, out var chatMessage))
    {
        Console.WriteLine(chatMessage);
    }
};

// Starting from 1.19, ChatType needs to be read from JoinGamePacket, otherwise some messages may not be displayed correctly.
if (Client.ProtocolVersion >= ProtocolVersions.V1_19)
{
    Client.PacketReceived += (m, args) =>
    {
        _ = JoinGamePacket.TryRead(args.Packet, out JoinGamePacket jgp) && jgp.TryGetChatTypes(out chatTypes);
    };
}

if (!Client.Connect()) // Connect to the server (TCP handshake)
    Console.WriteLine($"Failed to establish a connection with the server");
else if (!await Client.JoinAsync(playerName)) // Join the server (send login packet)
    Console.WriteLine($"Login failed");
else // Start listening for packets (PacketReceived event won't trigger if not listening)
    Client.StartListen(); 

while (Client.Joined)
{
    // Continuously listen for input from the command line and send it as a chat message to the server
    string Input = Console.ReadLine();
    await Client.GetPlayer()?.SendMessageAsync(Input);
}
