Features

  • Lightweight
    • Small CPU and RAM usage
    • Small packet size overhead ( 1 byte for unreliable, 4 bytes for reliable packets )
  • Simple connection handling
  • Peer to peer connections
  • Helper classes for sending and reading messages
  • Multiple data channels
  • Different send mechanics
    • Reliable with order
    • Reliable without order
    • Reliable sequenced (realiable only last packet)
    • Ordered but unreliable with duplication prevention
    • Simple UDP packets without order and reliability
  • Fast packet serializer (Usage manual)
  • Automatic small packets merging
  • Automatic fragmentation of reliable packets
  • Automatic MTU detection
  • Optional CRC32C checksums
  • UDP NAT hole punching
  • NTP time requests
  • Packet loss and latency simulation
  • IPv6 support (using separate socket for performance)
  • Connection statisitcs
  • Multicasting (for discovering hosts in local network)
  • Unity support
  • Support for .NET8 optimized socket calls (much less gc)
  • Supported platforms:
    • Windows/Mac/Linux (.NET Framework, Mono, .NET Core, .NET Standard)
    • Lumin OS (Magic Leap)
    • Monogame
    • Godot
    • Unity 2018.3 (Desktop platforms, Android, iOS, Switch)

Support developer

"Buy Me A Coffee"

Unity notes!!!

  • Minimal supported Unity is 2018.3. For older Unity versions use 0.9.x library versions
  • Always use library sources instead of precompiled DLL files ( because there are platform specific #ifdefs and workarounds for unity bugs )

Usage samples

Client

EventBasedNetListener listener = new EventBasedNetListener();
NetManager client = new NetManager(listener);
client.Start();
client.Connect("localhost" /* host ip or name */, 9050 /* port */, "SomeConnectionKey" /* text key or NetDataWriter */);
listener.NetworkReceiveEvent += (fromPeer, dataReader, deliveryMethod, channel) =>
{
    Console.WriteLine("We got: {0}", dataReader.GetString(100 /* max length of string */));
    dataReader.Recycle();
};

while (!Console.KeyAvailable)
{
    client.PollEvents();
    Thread.Sleep(15);
}

client.Stop();

Server

EventBasedNetListener listener = new EventBasedNetListener();
NetManager server = new NetManager(listener);
server.Start(9050 /* port */);

listener.ConnectionRequestEvent += request =>
{
    if(server.ConnectedPeersCount < 10 /* max connections */)
        request.AcceptIfKey("SomeConnectionKey");
    else
        request.Reject();
};

listener.PeerConnectedEvent += peer =>
{
    Console.WriteLine("We got connection: {0}", peer);  // Show peer ip
    NetDataWriter writer = new NetDataWriter();         // Create writer class
    writer.Put("Hello client!");                        // Put some string
    peer.Send(writer, DeliveryMethod.ReliableOrdered);  // Send with reliability
};

while (!Console.KeyAvailable)
{
    server.PollEvents();
    Thread.Sleep(15);
}
server.Stop();
