The test suite should cover:

• DeltaContainer (#14)
• Client
• Room
• Parsing complex MessagePack objects from the server
• Arrays support in patches (#15)

I am trying to run an example app, that just opens the connection to the server and joins a room. I am using the Chat server example, and created a small Unity app that connects.

Creating the Client works fine and I am getting the OnOpen event.

Then I am trying to join the room and I get the following 2 exceptions:
Error: An exception has occurred during an OnMessage event., System.InvalidOperationException: Cannot access child value on Newtonsoft.Json.Linq.JValue. at Newtonsoft.Json.Linq.JToken.get_Item (System.Object key) [0x00000] in <filename unknown>:0 at Colyseus.Patcher.Patch (Newtonsoft.Json.Linq.JToken& document, Newtonsoft.Json.Linq.JArray patches) [0x00000] in <filename unknown>:0 at Colyseus.Room.ApplyPatches (Newtonsoft.Json.Linq.JArray patches) [0x00000] in <filename unknown>:0 at Colyseus.Client.OnMessageHandler (System.Object sender, WebSocketSharp.MessageEventArgs e) [0x00000] in <filename unknown>:0 ...

And:
Error: An exception has occurred while receiving a message., WebSocketSharp.WebSocketException: The header part of a frame cannot be read from the data source. at WebSocketSharp.WebSocketFrame+<>c__DisplayClass7.<ReadAsync>b__6 (System.Byte[] header) [0x00000] in <filename unknown>:0 at WebSocketSharp.Ext+<>c__DisplayClass6.<ReadBytesAsync>b__5 (IAsyncResult ar) [0x00000] in <filename unknown>:0

My join code is pretty straight forward:
room = this.colyseus.Join ("chat_room");

I am using the binaries, and have not checked out from git, so maybe it's a problem that was fixed?

On the client which creates a new room will have this NullReference:

NullReferenceException: Object reference not set to an instance of an object

I can open other clients, join the room and everything works fine for them.

any idea why this could happen?

its pretty much the Start function from the docs:
https://github.com/BroProducts/mem-client/blob/master/MemMapPrototype/Assets/Scripts/Network/ColyseusClient.cs#L55

The Example Project modified so it has the use case which triggers the error in it
i only added 2 lines in the "server/chat_room.js" file.
Line 11 and Line 19
colyseus-unity3d-master-null-reference.zip

After reconnect client, if there is any state changes, the unity client room listener won't pick up any update on room state.
The reconnected client can send signal to server, but whatever server update on roomstate, the client won't receive any feedback. Anyone can help me?

Hello, i the previous version (before 0.10) i met some performances issue due to socker reading in coroutine then i move this in thread with queue system to process events.
Do you think than the v0.10 serialization will resolve this coroutine perfomance issue ?

Hi I tried the #44 but It seems still don't return list of available rooms in the callback. Please advise.

I opened the project using Unity 2017.2.0f3:

Assets/UnityTestTools/IntegrationTestsFramework/TestRunner/Editor/Batch.cs(71,29): error CS0619: UnityEngine.Application.isWebPlayer' is obsolete: This property is deprecated and will be removed in a future version of Unity, Webplayer support has been removed since Unity 5.4'

Good day!
What about authentication with callback answer before connecting to Room?
I haven't finded it in examples

Roadmap for compatibility with server v0.4.x:

• Implement binary delta patching (https://github.com/dchest/fossil-delta-js)
• Use FossilDelta on colyseus-unity3d client
• Compute the diff between previous and new state in the client-side
• Release version colyseus-unity3d v0.4.0

The changes introduced in #2 are a good starting point to support Unity WebGL export.

The main issue now is to have msgpack serialization working in the browser (msgpack/msgpack-cli#196)

I receive a key not found at https://github.com/colyseus/colyseus-unity3d/blob/master/Assets/Plugins/Colyseus/Serializer/Schema/Schema.cs#L335

I added logs to this file :
Each fields created at https://github.com/colyseus/colyseus-unity3d/blob/master/Assets/Plugins/Colyseus/Serializer/Schema/Schema.cs#L295

And log 335 line too.

Schema try to get an index not listed in 275 lines logs.

Try to get index 50 in a schema with 23 fields detected in constructor.

Fields generated by last version of c# generator (original version)

Version :
colyseus : 0.10.2
schema : 0.4.9

Hello, in the unity exemple, specificly in OnPlayerMove method, could i know which field changed ?
If only x changed or both.
In a class with more properties it can be usefull.

Thank you.

As discussed in the gitter channel, it would be nice to have two new event-handlers for onFirstStateReceived (to be able to build the initial game structure more easily) and onConnect.

The client does not react in any way when the connection with the server is lost.

Hi, I just trying your framework, and I found out if I minimize my game in android(press home button), onUpdateHandler will paused too. And then after I unpaused it(get back into the game), onUpdate will give me so many patches. And also my client will go into laggy condition(input became delayed until all previous patches applied). I think all the patches should become fast forward, so the player will catch up quite fast with the current time. Any suggestion about how to handle this issue?

Version 1.1.1 of the JavaScript package introduced this fix: colyseus/state-listener@63968cf

Need to replicate in the C# client, here: https://github.com/gamestdio/colyseus-unity3d/blob/012a063a821bb6432f65a5db1c90f0a48a29914e/Assets/Colyseus/DeltaListener/DeltaContainer.cs#L115

The patch Operation "add" does not work for Arrays in the gamestate. Instead, every time a new item gets pushed into it, the Operation for the patch is "replace" and the value is the full Array itself.

I could investigate this a bit further and found the origin of the Problem:
https://github.com/gamestdio/colyseus-unity3d/blob/master/Assets/Colyseus/DeltaListener/Compare.cs#L46
the type of oldVal and newVal in such cases is NOT Dictionary, but Array. So for Arrays the condition is always false and the else-case gets done.

In the JS-Client, this Problem does not exist because typeof [] = 'object'.

the Unity Client debug is showing state changes with op: "add" and path: "players", but the OnChangeFallback instead of OnAddPlayer is getting invoked. why?

regarding this piece:

chatRoom.state.Listen("players", "add", this.OnAddPlayer);
...
chatRoom.state.Listen(this.OnChangeFallback);

I believe that the OnAddPlayer function is set up to be the action listener for op: "add" and segment: "players", so why instead of it the function OnChangeFallback is getting invoked?

The C# client still doesn't dispatch deep "add" operations, as the JavaScript one does:
https://github.com/endel/delta-listener/blob/e3e50c6fe48057570b9fa45122343b957f1b9094/src/compare.ts#L80-L83

The Compare implementation in C# should generate deeper "add" operations too: https://github.com/gamestdio/colyseus-unity3d/blob/5223e7a5a84bf6f24164dd1961990c633b00a604/Assets/Plugins/Colyseus/DeltaListener/Compare.cs#L131-L143

Reported by @quanglam68 in the Gitter channel:

hi, I still learning the unity client. testing the code given for exchanging information with 2 clients and the server works fine. ex: trace in one client : OnUpdateHandler: { "players" : { "SkkPLJeag" : { "x" : 520, "y" : 0 }, "HJrDLkxpx" : { "x" : 255, "y" : 0 } } }
but when i make the data bigger in the server, this.state.players[client.id] = { a:0, b: 0, d:0, x: 0, y: 0 }; I have an error in the client when it tries to apply the patch

Exception: copy extends past end of input
Fossil.Delta.Apply (System.Byte[] origin, System.Byte[] delta) (at Assets/Colyseus/FossilDelta/Delta.cs:187)
Colyseus.Room.ApplyPatch (System.Byte[] delta) (at Assets/Colyseus/Room.cs:129)

Colyseus.Client.Recv () (at Assets/Colyseus/Client.cs:90)
ColyseusClient.FixedUpdate () (at Assets/Source/colyseus/ColyseusClient.cs:39)

My analysis is the pb appear at the call : this._previousState = Fossil.Delta.Apply (this._previousState, delta, out error);
seems that _previousState array size is too small. How can we set its size to it is bigger to match with the data set in the server

I Lost a day to understand and to change various things but I cannot find a solution / or even an quickfix

Any help is appreciated . Tks

Currently, the only way to cast the state to a specific data type is by de-serializing it again in the OnUpdate action:

room.OnUpdate += OnRoomUpdate;

   private void OnRoomUpdate(object sender, RoomUpdateEventArgs update)
    {
            var outputStream = new System.IO.MemoryStream();
            MsgPack.Serialize(update.state, outputStream);
            outputStream.Position = 0;
            this.gameRoom = MsgPack.Deserialize<GameRoom>(outputStream);

It would be great if the client allows to provide a data-type when joining the room - and use it for de-serializing automatically - for example:

client.Join<GameRoom>("game_room");

(Thanks for proposing @derwish-pro)

Same issue as the JavaScript client, see colyseus/colyseus.js#14

So with the newest Unity Version it will not work anymore since 'DynamicMethod' isnt anymore in the namespace 'System.Reflection.Emit'

So the problem is in the GameDevWare.Serialization dependency

Assets\Plugins\GameDevWare.Serialization\Metadata\ReflectionUtils.cs(86,34): error CS0246: The type or namespace name 'DynamicMethod' could not be found (are you missing a using directive or an assembly reference?)

Assets\Plugins\GameDevWare.Serialization\Metadata\ReflectionUtils.cs(142,34): error CS0246: The type or namespace name 'DynamicMethod' could not be found (are you missing a using directive or an assembly reference?)

@derwish-pro reported a problem in the DeltaContainer recently, with a patch: https://gist.github.com/derwish-pro/ecfd2c143b31816a408ef380e74ac21d

More info:

I have such a state of the game room on the server-side:

this.state.game.turn++;

I want to set a listener on the unity-side to catch this path. How can I do it?
I tried:

 room.Listen("game/turn", OnGameTurn);

and

  room.Listen("game/turn/:number", OnGameTurn);

None of the ways work.

I had to do a fix in DeltaContainer (unity side) to make it work.

When 5th client joins the server, then this error coming on client side.

Exception: bad checksum

After this error, 5th client not getting any messages from server.

(Reported by @aloani20 on gitter)

hi guys . I have this situation . on my client I was listening to property called "turn" using room.Listen ("turn", this.OnTurnChange); and the state on the server look like this

this.setState({
dice : 0 ,
turn : "none"
});

but when i mutate the value of dice i could see the change on the client but changing turn did not trigger this.OnTurnChange.

I have come up with a result that mutating javascript string variable on the server did not effect the room client listener.

Hi , i have a new bug , its full random , i cant reproduce by my self

Hi, i have a class A who contains a MapSchema of classes B.

class A extends Schema {
    @type({ map: B}) children= new MapSchema<B>();
}

When i add an element in MapSchema OnAdd is triggered (normal behaviour)

If i extend B with a C class :

class C extends B {

}

OnAdd is triggered with B type instead of C.

Debug :

A.children.OnAdd += OnAddBClass;

public void OnAddBClass(object sender, KeyValueEventArgs<B, string> item)
	{
		// Always B type here, cannot access to C fields, invalid casting when try to cast B to C
	}

Notes : all classes are generated and heritance too, C is see as B by c# compilator

When I launch the project, I get an error: a connection in my room is null.

Hi, i using 3 level nested structure :
Player --> Camp --> Position
Where camp is just a name/position
and Position is a vector of 3 floats

At the first player connection, all works fine.
But if i leave the room (it disposed : normal behaviour), and join a new one roomthen camp position is wrong (0,0,0).

If a restart the server, the first connection give me the good one camp position, and others connections send me a camp with 0,0,0 vector.

Note : i do not use any cache system.
All room state recreated from scratch

As reported by Chris Dillman:

Could you try running your unity test code under Unity 5.40f3 or around there the non beta version of unity.

Im getting an exception in

Where ["op"] does not seem to exist in the JArray.


public void Patch (ref JToken document, JArray patches) 

    string operation = patches [i]["op"].ToString(); 

and this is leading the client closing the connection.
This is immediately after successfully joining a room.

Thanks

The unity client can create and join the lobby if i don't use the sample part below.
Is this code piece really necessary to use the client?
`int i = 0;

	while (true)
	{
		client.Recv();

		i++;

		if (i % 50 == 0) {
			room.Send("some_command");
		}

		yield return 0;
	}`

Research the possibility to integrate this client on MonoGame.

Hello it works fine on the Editor. But when the Game is Running on a IOS Device (iPhone 5) it is not working. I get the following Debug log form xCode.

If i set a position of a Player in the server state to this:

currentPosition: {
  x: -30,
  y: 2.02,
  z: 0
}

on the client its this:

currentPosition: {
  x: 2,
  y: 2.02,
  z: 0
}

Client Side Code which prints out x wrong.
in debug u see its in DataChange already false

void OnPlayerChange (DataChange change)
{
	Debug.Log ("OnPlayerChange");
	Debug.Log (change.operation);
	Debug.Log (change.path["id"]);
	Debug.Log (change.value);

	var data = (IndexedDictionary<string, object>) change.value;

	var currentPosition = (IndexedDictionary<string, object>) data["currentPosition"];

	var x = Convert.ToSingle (currentPosition ["x"]); //prints out 2 but should be -30
	var y = Convert.ToSingle (currentPosition ["y"]);
	var z = Convert.ToSingle (currentPosition ["z"]);
}

Modified Version of the Unity client example which set the spawn of the cube to this

modified client so he sets also the Z:

actual spawn: (ignore X because its already moved by script)

Unity will bring ECS this year and some stuff is already out.
I think Colyseus would work really great with the unity ECS.
I opened this issue to bring it up.

Maybe i would already be enough to just change the ColyseusClient example.

When I set my room metadata, even at Client.cs:220 you can see that metadata is null in the received object.

  onInit(options: any): void {
    this.setState(this.initialPlayerState());
    this.maxClients = options.maxClients || MAX_PLAYERS_IN_ROOM;
    this.setMetadata({
      mode: options.mode || '',
      name: options.name || `Room ${this.roomId}`,
    });
  }

I tried JSON.stringifying the metadata object, still don't get a string on the client side.

onClose event dose not work !

Hi!!!
Why in Client.cs commented code part with function GetAvailableRooms?
When that will be fixed and i can work with that?

//		public void GetAvailableRooms (string roomName, Action<RoomAvailable[]> callback)
//		{
//			int requestId = ++this.requestId;
//			this.connection.Send (new object[]{Protocol.ROOM_LIST, requestId, roomName});
//
//			this.roomsAvailableRequests.Add (requestId, callback);
//
//			// // USAGE
//			// this.client.GetAvailableRooms ("chat", (RoomAvailable[] obj) => {
//			// 	for (int i = 0; i < obj.Length; i++) {
//			// 		Debug.Log (obj [i].roomId);
//			// 		Debug.Log (obj [i].clients);
//			// 		Debug.Log (obj [i].maxClients);
//			// 		Debug.Log (obj [i].metadata);
//			// 	}
//			});
//		}

The problem is that the room does not dispose even after all of the clients leave. Then if another player searches for room to join he gets connected to this room with the "ghost" client.

The room gets finally disposed only after the game is re-launched by the client who initially created the room. Weird.

This happens only if the clients leave by instantly closing the application.

void OnApplicationQuit()
{
    // Ensure the connection with server is closed immediatelly
    LeaveRoom();
    if (Colyseus != null) Colyseus.Close();
}

public void LeaveRoom()
{
    if (Room != null)
    {
        Room.Leave(true);
    }
}

void OnRoomLeft(object sender, EventArgs e)
{
    Room = null;
}

Need to apply the same patch as the JavaScript version: colyseus/state-listener@37897b4

Hi, i have a class A extending schema and another class B extending the A at generation fields with @type decorator in A are not present in class B, and c# class B extends schema and not class A.
Any solution for this ?

Thank you.

Event handlers like OnJoin in Room class are not null checked before trying to invoke.

I will fix this and send a pull request

Hi there! I have just discovered Colyseus and I'm trying to use it in a simple Unity game just to see how it feels. I am having trouble understanding how to trigger OnPlayerMove. I tried something like this in Unity:

string[] coordsX = {"x", transform.position.x.ToString() };
chatRoom.Send(coordsX);

but it doesn't seem to do anything. Can you give me a small example on how to do this? Thank you!

If u add a listner to onData u dont get the data

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

The data is private and so u cant accessible

Hi, I want to use colyseus in a project where I have to write a Unity Windows UWP App. When I wanted to build the project, I got an error message because the WebSocket implementation doesn't work on UWP.
Now I thought I could add another preprocessor-directive in WebSocket.cs and write the needed functions with a WebSocket implementation for UWP (https://docs.microsoft.com/en-us/windows/uwp/networking/websockets).

I just wanted to make sure, which functions I have to write for this. I'm thinking, it's

Send()
Recv()
Connect()
Close()

am I right?

Hi, i tried to externalize X and Y in unity exemple, in a Position schema and look for changes in this new Schema and X increment in JS onMessage method.
I regenerated the c# classes, change the code accordly and register an handler on the position in OnPlayerAdd method like this :

item.Value.position.OnChange += OnPositionChange;

I do not receive any event from position change. Server debug changes on Position.

Here the source code.

Thank you for your help.

Hi,

I might not be using the right terms to describe what I want to achieve but please bear with me on the following description:

This is from he example code ColyseusClient.cs

room.Listen ("players/:id/:axis", this.OnPlayerMove);
room.Listen ("players/:id", this.OnPlayerChange);
room.Listen ("messages/:number", this.OnMessageAdded);
room.Listen("test_messages/:odd_numbers", this.OnMessageAdded);

Where do I check to find the key axis this set in players object?
Where do I check to find the key number for messages?

How do I add new keys?
For example,
constructor () {
super();

this.setState({
  players: {},
  messages: [],
  test_messages: []
});

}

In test_messages I would like a key to be name "odd_numbers" instead of numbers, how to change it? Or documentation explaining this would help.
