Network Transport

The NetworkTransport is a base class used to define how communication between network endpoints will be handled. You can implement your own transport to support any kind of connection protocol you desire, such as Bluetooth, etc...

public abstract class NetworkTransport : MonoBehaviour
{
    #region ManagementMethods
    public abstract void StartHost(int magicNumber);
    public abstract void StartServer();
    public abstract void StartClient(int magicNumber);
    public abstract void Close();
    #endregion

    #region Client Methods
    public abstract IClientConnectionInfo GetClientInfo(int id);
    public abstract int GetClientCount();
    public abstract IEnumerable<IClientConnectionInfo> GetClients();
    #endregion

    #region Lifecycle
    public abstract void ClientDisconnect(string reason);
    public abstract void ServerDisconnect(int id, string reason);
    public abstract void SendClientPacket(IPacket packet, bool reliable = false);
    public abstract void SendServerPacket(IPacket packet, int target = -1, bool reliable = false);

    public void BroadcastServerPacket(IPacket packet, bool reliable = false)
    {
        SendServerPacket(packet, -1, reliable);
    }
    #endregion
}

Local

The LocalNetworkTransport is the most basic network transport method. With local network transport, you can add support for split-screen mode without any additional coding required (just manage player input separately): each action will be seamlessly handled, even locally.

UDP

UDP (User Datagram Protocol) is the primary gaming network protocol, thus it's the basic internet-based protocol supported. Currently, UDP connection is established using the LiteNetLib library, which provides custom reliability systems that fit our gaming needs perfectly.

In the UDPNetworkTransport component, you can set the host/remote address, host/remote port, connection password, and maximum server client limit.
