LLAPI - ConnectionID of clients are the same

Unity Engine
1

Hi

I am putting together a small prototype using the llapi, so the problem is the connectionID for clients are the same. So I run my server, in the update method, connect event I Debug.Log("Client connected " + connectionId); Just for testing so I know who has connected. But in my client Network.Connect always returns connectionID 1. Here is the code for my server and client, Also remember I am running both Server and 2 Clients on the same machine.

public class ServerNetworkManager : MonoBehaviour
{

    #region Fields

    public static ServerNetworkManager instance = null;

    public delegate void MessageHandler(Message msg);
    public static event MessageHandler OnHandleMessage;

    // network
    private const int MAX_CONNECTIONS = 100;
    private int port = 6321;
    private int serverID;
    private int webHostID;
    private int channelID;
    private byte error;
    private bool isStarted = false;
    public List<Player> Players;

    // UI
    public Text lblConnected;

    #endregion

    void Awake()
    {
        if (instance == null) instance = this;
        else if (instance != this) Destroy(gameObject);
    }

    private bool Initialize()
    {
        NetworkTransport.Init();

        var config = new ConnectionConfig();
        channelID = config.AddChannel(QosType.ReliableSequenced);
        var toplogy = new HostTopology(config, MAX_CONNECTIONS);

        serverID = NetworkTransport.AddHost(toplogy, port, null);
        webHostID = NetworkTransport.AddWebsocketHost(toplogy, port, null);

        isStarted = true;
        Debug.Log("Sever started on port " + port);

        DontDestroyOnLoad(gameObject);

        Players = new List<Player>();

        return true;
    }
   
    void Start()
    {
        Initialize();
        lblConnected = GameObject.Find("lblConnectedClients").GetComponent<Text>();
        lblConnected.text = "Connected: 0";
    }

    void Update()
    {
        if (isStarted == false)
            return;

        int recHostId;
        int connectionId;
        int channelId;
        byte[] recBuffer = new byte[1024];
        int bufferSize = 1024;
        int dataSize;
        byte error;

        NetworkEventType recData = NetworkTransport.Receive(out recHostId, out connectionId, out channelId, recBuffer, bufferSize, out dataSize, out error);

        switch (recData)
        {
            case NetworkEventType.ConnectEvent:
                Debug.Log("Client connected " + connectionId);
                AddPlayer(connectionId);
                break;

            case NetworkEventType.DataEvent:
                string msg = Encoding.Unicode.GetString(recBuffer, 0, bufferSize);
                var message = JsonUtility.FromJson<Message>(msg);
                OnHandleMessage(message);
                break;

            case NetworkEventType.DisconnectEvent:
                var player = Players.First(p => p.ConnectionID == connectionId);
                Players.Remove(player);
                UpdateConnected();
                break;
        }
    }
}

Here is the client code :

public class ClientNetworkManager : MonoBehaviour
{
    public static ClientNetworkManager instance = null;

    public delegate void MessageHandler(Message msg);
    public static event MessageHandler OnHandleMessage;

    // network
    private const int MAX_CONNECTIONS = 100;
    private int _port = 6321;
    private int _serverID;
    private int _channelID;
    private byte _error;
    public int ConnectionID { get; set; }

    // UI
    public Text lblStatus;

    void Awake()
    {
        if (instance == null) instance = this;
        else if (instance != this) Destroy(gameObject);

        lblStatus = GameObject.Find("lblStatus").GetComponent<Text>();
        lblStatus.text = "Status: Not Connected";
    }

    void Start()
    {
        NetworkTransport.Init();
    }

    void Update()
    {
        if (ConnectionID == 0)
            return;

        int recHostId;
        int connectionId;
        int channelId;
        byte[] recBuffer = new byte[1024];
        int bufferSize = 1024;
        int dataSize;
        byte error;

        NetworkEventType recData = NetworkTransport.Receive(out recHostId, out connectionId, out channelId, recBuffer, bufferSize, out dataSize, out error);
        switch (recData)
        {
            case NetworkEventType.DataEvent:
                string msg = Encoding.Unicode.GetString(recBuffer, 0, bufferSize);
                var message = JsonUtility.FromJson<Message>(msg);
                OnHandleMessage(message);
                break;
        }
    }

    public void Connect()
    {
        if (ConnectionID > 0)
            return;

      
        var config = new ConnectionConfig();
        _channelID = config.AddChannel(QosType.ReliableSequenced);
        var toplogy = new HostTopology(config, MAX_CONNECTIONS);

        _serverID = NetworkTransport.AddHost(toplogy, _port, null);
        ConnectionID = NetworkTransport.Connect(_serverID, "127.0.0.1", _port, 0, out _error);

        Debug.Log(ConnectionID);

        lblStatus.text = "Status: Connected - " + ConnectionID.ToString();
    }

    public void SendMessageToServer(Message message)
    {
        var json = JsonUtility.ToJson(message);
        byte[] msg = Encoding.Unicode.GetBytes(json);
        NetworkTransport.Send(_serverID, ConnectionID, _channelID, msg, json.Length * sizeof(char), out _error);
    }

}

I think I have been looking at this code for to long and I cant see my mistake.
Thanks for helping.

UNet LLAPI - Every connected client to a server is getting connection ID 1 from Connect method
2

You gotta sync that yourself. From my experiance. The ConnectionId’s are not synced. So just add it to your connection flow.
