A fluent networking library build on top of lidgren network. Ginet extends lidgren network with a fluent and functional API.
Ginet is available as a NuGet package. You can install it using the NuGet Package Console window:
PM> Install-Package Ginet
Ginet favors message exchange. All classes that are handled via the INetworkManager must be marked with the GinetPackageAttribute. Ginet inferres messages by adding a unique byte id.
The classes must be marked as public with public getters / setters and contain only primitive types. The client and server registered packages should be the same. For complex serialization you can provide your custom serializer via attribute.
[GinetPackage]
public class MyPackage
{
public string Message { get; set; }
}
[GinetPackage]
public class ConnectionApprovalMessage
{
public string Sender { get; set; }
public string Password { get; set; }
}
A simple client-server chat example here.
Create, configure and register the classes that are marked with the GinetPackage attribute
var server = new NetworkServer("MyServer",
builder =>
{
//via reflection
builder.RegisterPackages(Assembly.Load("Packages.Assembly.Name"));
//or manually
builder.Register<MyPackage>();
},
cfg =>
{
cfg.Port = 1234;
cfg.ConnectionTimeout = 5.0f;
//Additional configuration
});
server.IncomingMessageHandler.LogTraffic();
Start the server
server.Start(NetDeliveryMethod.ReliableOrdered, channel: 0);
Process Incoming Messages in a separate thread
server.ProcessMessagesInBackground();
If you have an update loop you can await the message processing in an async method
await server.ProcessMessages()
Configure how to respond to incoming packages
server.Broadcast<ChatMessage>((msg, im, om) =>
{
server.Out.Info($"Received {msg.Message}");
server.SendToAllExcept(om, im.SenderConnection, NetDeliveryMethod.ReliableOrdered, channel: 0);
},
packageTransformer: msg =>
msg.Message += "this is broadcasted");
server.BroadcastExceptSender<ChatMessage>((sender, msg) =>
{
server.Out.Info($"Broadcasting {msg.Message}. Received from: {sender}");
});
Configure context specific behavior with the NetIncomingMessageType and NetConnectionStatus enums
server.IncomingMessageHandler.OnMessage(NetIncomingMessageType.ConnectionApproval, incomingMsg =>
{
//Configure connection approval
var parsedMsg = server.ReadAs<ConnectionApprovalMessage>(incomingMsg);
if(parsedMsg.Password == "my secret and encrypted password")
{
incomingMsg.SenderConnection.Approve();
incomingMsg.SenderConnection.Tag = parsedMsg.Sender;
}
else
{
incomingMsg.SenderConnection.Deny();
}
});
server.IncomingMessageHandler.OnConnectionChange(NetConnectionStatus.Disconnected, incomingMsg =>
{
server.SendToAllExcept(
server.ConvertToOutgoingMessage(new MyPackage
{ Message = $"Disconnected {incomingMsg.SenderConnection}" }),
im.SenderConnection,
NetDeliveryMethod.ReliableOrdered,
channel: 0);
});
server.IncomingMessageHandler.OnConnection(server.Host.Connections.First(), (msgType, incomingMsg) =>
{
//...
});
Upon adding a handler, an IDisposable object is returned. Disposing it causes the handler deregistration.
var handlerDisposable = server.IncomingMessageHandler.OnMessage(NetIncomingMessageType.Data, im => { });
handlerDisposable.Dispose();
Create, configure and register the classes that are marked with the GinetPackage attribute
var client = new NetworkClient("Chat",
builder=>
builder.RegisterPackages(Assembly.Load("Packages.Assembly.Name")),
cfg =>
{
//client configuration
});
Start / Connect
client.Start(NetDeliveryMethod.ReliableOrdered, channel: 0);
client.Connect("localhost", 1234, new ConnectionApprovalMessage
{
Sender = "Me",
Password = "1234"
});
Process Incoming messages
client.ProcessMessagesInBackground();
Handle incoming messages
client.IncomingMessageHandler
.OnPackage<MyPackage>((msg, sender) =>
Console.WriteLine($"Received {msg.Message} from {sender.SenderConnection}"));
Send a message
client.Send(new MyPackage { Message = "Hello" },
(om,peer) => peer.SendMessage(om,NetDeliveryMethod.ReliableOrdered));
Create a message sender lifter
IPackageSender packageSender = client.LiftSender((msg, peer) =>
peer.SendMessage(msg, NetDeliveryMethod.ReliableOrdered));
packageSender.Send(new MyPackage { Message = "Hello" });
For custom logging targets implement the IAppender interface and pass it in the client , server creation
var server = new NetworkServer(
"MyServer",
cfg => {},
output: new MyAppenderImplementation());
The default IAppender uses the Console.WriteLine in the ActionAppender constructor.
var server = new NetworkServer(
"MyServer",
cfg => {},
output: new ActionAppender(Console.WriteLine));
For custom encoding / decoding for a type, simply implement the IPackageSerializer interface add the PackageSerializerAttribute to the class
[GinetPackage]
[PackageSerializer(typeof(MyCustomSerializer))]
public class MyPackage
{
public string Message { get; set; }
}
