extension-networking's Issues

client.send in Android doesn't seem to be working

Hi, after establishing a Server in Windows, opening a Client in Android and connecting to server from the client, trying:

server.send({ x: "something"});

doesn't seem to register on the android client. Maybe I am missing something here though.
I can provide the HaxeDevelop project, with both the server and the client, if needed.
It's a simple in house project so no NDA.

Migrate to CircleCI 2.0

CircleCI needs to be updated to version 2.0 according to this.

Flash sockets error

The following error is being generated on the client side while targeting flash:

Error #2044: Unhandled IOErrorEvent:. text=Error #2031: Socket Error.

 ...

Things to try:

Use latest Haxe, Lime and OpenFL versions. Fixes nothing.
Isolate the error in a small project. Fixes nothing.

Required fixes:

Refactor library sockets (openfl.net.Socket) to use events instead of synchronous behaviour.
Add a XmlPolicyFileServer to handle flash policy files.
Create a wiki page about How to allow flash clients. Please, check #4.

Second client that joined the server cannot receive the message

Hello, I'm creating a multiplayer game using HaxeFlixel and this library. Currently, I have a server program that sends a certain message when player joins the game and gives the player a certain ID. The first client gets the message and gets the ID 0, but the second client that joined does not get the message and gets the ID null. I want to get assistance with this issue.

The code in the server that runs when player joins (I know that variable names are bad):

// ...
server.addEventListener(NetworkEvent.MESSAGE_RECEIVED, function(event:NetworkEvent)
{
	switch (event.data.case1)
	{
		case "player_joined":
			var previousPlayers = players.members.slice(0, players.members.length - 1);
			trace("Previous players: " + previousPlayers);
			server.send({case1: "new_player", players1: previousPlayers, playerID: newestID});
			trace("Sended");
			newestID++;
	}
});
// ...

The code in the client that runs when the client receives the message:

// ...
client.addEventListener(NetworkEvent.MESSAGE_RECEIVED, function(event:NetworkEvent)
{
	trace("Client received a message");
	// If case is new player, add a player
	switch (event.data.case1)
	{
		case "new_player":
			trace("Message: new player");
			var playersArr:Array<FlxSprite> = event.data.players1;
			for (i in playersArr)
			{
				i.loadGraphic(AssetPaths.PlayerCharacter__png, true, 32, 32);
				otherPlayers.add(i);
			}
			playerID = event.data.playerID;
			trace("Player ID: " + playerID);
	}
});
// ...

How can I upload the server part on my VPS to run forever ?

Hope you don't mind as I have got many questions ( not issues ).
I know how to compile the haxe files. But I am not sure about how to use it as server on my VPS
How can I upload the server part on my VPS to run it forever?
Would it be feasible to use it for production? For Android?
Is it possible to make the client files kept on a web-hosting to communicate with the VPS having the server file?

Websockets connecting to native server

This is more of a question, rather than an issue.

I can get a client and server both running in neko to connect perfectly, but when I try to run a server in neko and the client in html5 I get the following errors:

Client side

Are connections from web sockets -> native sockets not supported?

Wrong disconnection events order for clients

When a client closes his session, the following events are being fired:

- NETWORK_EVENT_CLOSED
- NETWORK_EVENT_DISCONNECTED

They should be fired in the following order:

- NETWORK_EVENT_DISCONNECTED
- NETWORK_EVENT_CLOSED

Uncaught exception - Invalid call from networking.sessions.Session::disconnectClient line 124

I get the following exception when calling the disconnectClient() method on a Server-Session.

Called from networking.sessions.Session::disconnectClient line 127
Uncaught exception - Invalid call

To repoduce, you can instanciate the attayched class and try to connect two clients.
After connecting the second client, the first one should be disconnected but instead the Application crashes.

CommandServer.zip

How ever I was able to fix this issue by Modifieing the disconnectClient() method in Session.hx to this:
(Castes the network_item from Dynamic to Server Class )


public function disconnectClient(cl: ClientObject = null) {
  switch(mode) {
    case SERVER:
      if (network_item == null || cl == null) return;
      var server:Server = network_item;
      server.disconnectClient(cl);

    case CLIENT:
      if (network_item == null) return;
      stop();
  }
}

Would love html5 support

currently building a creation, idea, problem database app in openfl, however a simple html5 version would be very helpful for marketing and in order to reach a wider audience.

README.md is getting too big

Let's move the documentation to the wiki!

Demo 'basic-example' crashes on neko when starting server

I am attempting to compile under Neko (lime run neko). When pressing the 'Server' button in the 'basic-example' demo, the application crashes with this error message:

I am running on Mac OSX, using Haxe 3.4.

"Critical Error: Allocating from a GC-free thread" when using VSCode debugger

I am not certain that the issue I am experiencing is directly related to this library. However, after producing this minimal example, I believe that some connection may exist.

Versions:

Haxe: 4.0.0-preview.4+1e3e5e016
Lime: 7.0.0
OpenFL: 8.4.1
extension-networking: 1.4.2
hxcpp: 4.0.4
hxcpp-debug-server (i.e. hxcpp debugger): 1.0.0
Visual Studio Code: 1.26.1

Steps to reproduce:

Open the folder examples/basic-example in Visual Studio Code.
Set Build Target to Windows, Build Configuration to Debug.
Ctrl-Shift-B to build (lime build windows -debug --connect 6000)
In the Debug sidebar, select a Windows/HXCPP configuration.

I used the following:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Hxcpp",
            "type": "hxcpp",
            "request": "launch",
            "program": "${workspaceRoot}/bin/windows/bin/basic-example.exe"
        }
    ]
}

Start debugging.

The program begins fine, but as soon as I click "Server," I get the message Critical Error: Allocating from a GC-free thread and the program terminates.

If I try to simply run the same program (no recompilation) without debugging (lime run windows -debug --connect 6000), everything seems to work as expected.

Ios Support

Hey sorry to ask again for support but I'm just curious if ios does works as a client. I'm testing my project in an ios simulator and looking at the network support it shows that it does indeed have a connection to the server and how it is sending packets however the server is not receiving them in the slightest. Also the server is getting connected and disconnected calls from the simulation. Any help would be very much apperciated 😄
