NetworkVariable of Struct or Class leads to infinite hang when on Player Gameobject

[Sebastian-Schuchmann]

Description

Hello, I have this

public class ClientStateLocal : NetworkBehaviour
{
   public NetworkVariable<ClientTest> test;
}

which is just a simple struct (class has the same issue)

    [Serializable]
    public struct ClientTest : IEquatable<ClientTest>
    {
        public bool isModerator;
        public bool calibrationActive;

        public bool Equals(ClientTest other)
        {
            return isModerator == other.isModerator && calibrationActive == other.calibrationActive;
        }

        public override bool Equals(object obj)
        {
            return obj is ClientTest other && Equals(other);
        }

        public override int GetHashCode()
        {
            return HashCode.Combine(isModerator, calibrationActive);
        }
    }

And when this network variable is on the player spawned gameobject it just hangs. In the scene it is fine. When changing it to an int or some built-in type (I have not tried everything) it is fine. The editor is just frozen which makes it hard to debug.

Am I doing something wrong? I have a basic Netcode Setup, the Player Gameobject has just this component with just this Network Variable and of course Network Object and that is it. It just hangs.

This is on the latest version 2.12 but also on 2.10. MacOS Unity 6.3 LTS (6000.3.13f1)

Help would be appreciated!

I fixed it, the error was mostly on my part as I was creating the loop myself. When host starting failed, I started host again. But I still have a question.

[GenerateSerializationForType(typeof(ClientData))]

This did not work for me. But I had to do this.

public class ClientData : IEquatable<ClientData>, INetworkSerializeByMemcpy

Is this how it is intended?

#4007 has some updated docs around custom serialization that should hopefully make some of this area clearer. Glad you were able to figure out what was going on!
