@endel I was looking at this in a tired state, but im pretty sure i had fully updated client and server. Ill double check what i was seeing and if i still have an error I'll open an issue on the github. Thanks for the response.

@endel hey sir im still struggling with initial sync, here is my setup.

Error i'm receiving:

Colyseus.Room.ParseMessage (System.Byte[] recv) (at Assets/Plugins/Colyseus/Room.cs:140)
Colyseus.Room.Recv () (at Assets/Plugins/Colyseus/Room.cs:73)
Colyseus.Client.Recv () (at Assets/Plugins/Colyseus/Client.cs:90)
RoomHandler+<Start>c__Iterator0.MoveNext () (at Assets/RoomHandler.cs:37)
UnityEngine.SetupCoroutine.InvokeMoveNext (IEnumerator enumerator, IntPtr returnValueAddress) (at /Users/builduser/buildslave/unity/build/Runtime/Export/Coroutines.cs:17)

Here is my data from server:

Code section its dying on (Room.cs) in plugins:

} else if (code == Protocol.ROOM_STATE) {
				byte[] encodedState = (byte[]) message [2];

				// TODO:
				// https://github.com/deniszykov/msgpack-unity3d/issues/8

				// var remoteCurrentTime = (double) message [3];
				// var remoteElapsedTime = (int) message [4];

				// this.SetState (state, remoteCurrentTime, remoteElapsedTime);

				this.SetState (encodedState, 0, 0);

			}

And finally, my start function

IEnumerator Start () 
    {
        client = new Colyseus.Client ("ws://localhost:2657");
        client.OnOpen += OnOpenHandler;
        client.OnClose += (object sender, EventArgs e) => room.Leave();

        yield return StartCoroutine(client.Connect());

        room = client.Join("game");
        room.OnReadyToConnect += (sender, e) => StartCoroutine ( room.Connect() );
        room.Listen ("messages/:number", this.OnMessageAdded);
        room.Listen ("players/:id", this.OnPlayerAdded);
        room.Listen ("shared/:map/:bases/:id", this.OnBaseAdded);
        room.OnJoin += OnRoomJoined;
        room.OnUpdate += OnUpdateHandler;

        room.OnData += (object sender, MessageEventArgs e) => Debug.Log(e.data);

        while (true)
        {
            client.Recv();

            // string reply = client.RecvString();
            if (client.error != null)
            {
                Debug.LogError ("Error: " + client.error);
                break;
            }

            yield return 0;
        }

        OnApplicationQuit();
    }

Have any initial thoughts?

@endel what a quick turnaround! thank you!

I will try out my project and see if this fixes what i was struggling with.

@endel Thoughts on how you would implement this in Unity?

Also do you have a good example of a first state sync of a complex state structure in Unity?

Nevermind.......

As soon as i hit submit i see i dont have break in my JS switch code on the server...

/facepalm.

Loving the library so far, great work!

Hey there,

This might just be a lack of me understanding so I apologize in advance if so, but i seem to be having some trouble understanding the state sync.

Also know the code is just thrown together for learning purposes and to see if i can get something working.

My Server Code:

export class Player {
    id: string;

    position: {
        x: number,
        y: number,
        z: number
    } = {
        x: 0,
        y: 0,
        z: 0
    };

    updatePosition(key) {
        switch(key) {
            case 'A':
              this.position.x -= 0.1;
            case 'S':
              this.position.z -= 0.1;
            case 'D':
              this.position.x += 0.1;
            case 'W':
              this.position.z += 0.1;
            default:
              break;
        }
    }
}

Then in the main Room code after a player has joined, i listen for a input message and call the above code with this:

onMessage (client, data) {
    console.log(client.id, "sent", data)

    if (data.action) {
      if (data.action === 'Input') {
        this.handleMovement(client.sessionId, data.key)
      }
    }
  }

handleMovement (id, key) {
    this.state.players[id].updatePosition(key);
  }

In my unity client side i have this code.

IEnumerator Start () {
        ...
        room.Listen ("players/:id/:position/:attribute", this.OnPlayerChange);
        ...
}

void HandlePlayerInput() 
{
        if (Input.GetKeyDown("a"))
        {
            room.Send(new { action = "Input", key = "A"});
        }
        if (Input.GetKeyDown("s"))
        {
            room.Send(new { action = "Input", key = "S"});
        }
        if (Input.GetKeyDown("d"))
        {
            room.Send(new { action = "Input", key = "D"});
        }
        if (Input.GetKeyDown("w"))
        {
            room.Send(new { action = "Input", key = "W"});
        }
}

void OnPlayerChange(DataChange change) 
{
        GameObject curPlayer;
        players.TryGetValue(change.path["id"], out curPlayer);

        if (curPlayer)
        {
            switch (change.path["attribute"])
            {
                case "x":
                    curPlayer.transform.position = new Vector3(float.Parse(change.value.ToString()), curPlayer.transform.position.y, curPlayer.transform.position.z);
                    break;
                case "y":
                    curPlayer.transform.position = new Vector3(curPlayer.transform.position.x, float.Parse(change.value.ToString()), curPlayer.transform.position.z);
                    break;
                case "z":
                    curPlayer.transform.position = new Vector3(curPlayer.transform.position.x, curPlayer.transform.position.y, float.Parse(change.value.ToString()));
                    break;
                default:
                    break;
            }

        }
}

All of this works Kinda great. I see the box spawn, i can kinda move it around, but the movement isn't perfect.

When i hit the "a" key nothing happens. I logged once on the server and it is setting my players x position to -0.1, but the message never seems to come to unity.

When i hit "w" all works as expected. (box moves up the z plane, camera is directly above box so x,z planes are the movements.)

When i hit "d" the box moves both up the x plane and the z plane in a diagonal direction?

And finally when i hit the "s" button nothing happens.

Any ideas as to what i might be doing wrong?

Thanks,
Cody
