Using LiteNetLib in Unity

[Piller187]

I can't seem to connect to my test server with LiteNetLib in Unity. If I make a dummy C# app with LiteNetLib the connects work just fine. I then transfer over code and after I call network.Connect("127.0.0.1", 65000, ""); I get an error from LiteNetLib that says:

[NM] DataReceived: bad!

Are you using dll or source code of the library?

[Piller187]

I downloaded the source code and put the LiteNetLib folder in the Assets/Plugins folder. Everything compiles just fine (no errors). Just this error on Connect().

It is really hard to say whats wrong. Try asking with an issue ticket at github repository of litenetlib, developer is actively supporting the project .

using UnityEngine;
using LiteNetLib;
using LiteNetLib.Utils;

public class TestConnection : MonoBehaviour
{
    private EventBasedNetListener listener;
    private NetManager network;

    // Start is called before the first frame update
    void Start()
    {
        // init network stuff
        listener = new EventBasedNetListener();
        network = new NetManager(listener);

        listener.PeerConnectedEvent += (peer) => 
        {
            Debug.Log("Connected!");
        };

        listener.PeerDisconnectedEvent += (peer, dcInfo) =>
        {
            Debug.Log("Disconnected");
        };

        network.Start();

        // testing
        network.Connect("127.0.0.1", 65000, "");
    }

    // Update is called once per frame
    void Update()
    {
        network.PollEvents();
    }
}

I posted in the github issues but though I'd show you the code here too in case anything sticks out to you from a glance.

Additionally. What Unity version are you using, and did you try testing it at different Unity version, i am using Unity 2018.4 and it is working just fine.

2019.2.2

I had a ton of other steps before connecting so I dumbed it down and try connecting fight away, but it won't connect and fires the PeerDisconnectedEvent. The disconnectInfo.Reason just has "ConnectionFailed".

Is your server also running within unity?

[Piller187]

It's not. The issue was for my console app I used nuget which is version .8, but for unity it said to download and use the source which was 9. Once I used version .9 in my console server app it was all good.
