Network events not working

[xelamak]

Hello developers,

Currently on UrhoSharp 1.2.21 Network Events are not working as expected. I have tested the Chat Sample on both UrhoSharp and latest Urho3D from master branch, and here are the results:

Server	Client	Connect	Send Message
Urho3D	2xUrhoSharp & 1xUrho3D	Successful	Urho3D Working normally, UrhoSharp can send but won't receive any messages
UrhoSharp	1xUrhoSharp & 2xUrho3D	Successful	Both UrhoSharp&Urho3D not working, pressing send can clear the text but nothing appears in chat history

The result leads me to a guess that Network events subscription on UrhoSharp are not working, I have created a simple application and subscribed to several network events. And here are the results:

Event	Result (Client)	Result (Server)
NetworkMessage	The event handler was not called when client sent message to server	The event handler was not called when server sent message to client
ClientConnected	Not applicable	Console displays client connected message correctly, but the user event handler was not called
ClientDisconnected	Not applicable	Console displays client disconnected message correctly, but the user event handler was not called
ConnectFailed	Not tested	Not tested
NetworkSceneLoadFailed	Not tested	Not tested
NetworkUpdate	Called frequently (Every frame? Not sure, but the function was called continuously)	Same as Client
NetworkUpdateSent	Handler called after every NetworkUpdate	Same as client
ServerConnected	Event Handler called on connected to server	Not applicable
ServerDisconnected	Event Handler called on disconnected from server	Not applicable

Example code of subscribing to NetworkMessage:

public class Server : Application {
    ...
    protected override void Setup(){
        base.Setup();
        Network.NetworkMessage += (arg) => {
            Urho.IO.Log.Write(LogLevel.Debug, "Network Message");
        };

        ... (subscribe to other events)
    }
    ...
}

@xelamak thanks for the detailed bug report, I am investigating...

[xelamak]

Thanks, I have also tried building UrhoSharp with latest Urho3D source myself but the problem still exists.

Is there any update ?

Hi Egorbo,

Is there any scheduled plan to fix the network events issue ? Is there any work around to solve the problem.

+1 to this. I'm sending messages but not receiving any via the NetworkMessage event. I'm using an alternative networking library for the moment, please let us know if there are any updates!

+1 - Confirmed on 1.9.67. I cannot get NetworkMessage, ClientSceneLoaded, ClientDisconnected to fire using SubscribeToEvent or event handler syntax (Network.NetworkMessage += (arg) => {};).

+1 - ClientConnected is nor called, so it is not possible to assign der scene on the server-side

Has anyone found a workaround for this?

[barefists]

For anyone this is troubling, I'm using an alternative networking library called LiteNetLib at the moment, works well with Urhosharp.

[CobraCalle]

Can you give me a hit, how to tell Urho to use LiteNetLib? Becouse I want to do Scene Replication, so I need the ClientConnected-Event to set the scene that soulf be replicated....

[barefists]

I don't think there's an automated way of doing it, you'll need serialize the scene into json or xml, send it over the network, then parse it on the other end.

Do you have any LiteNetLib UrhoSharp project published as open source?

@barefists also does it work on mobile?

[barefists]

Yes it works on mobile - I don't have any open source project I can share right now with working code, unfortunately.
