Auto reconnection keeps running after exit play mode in Unity editor

[jingfu-wei]

Greetings! I am having so much fun with SocketIOUnity. Thank you very much for this.

I have run into a problem, where I found the child thread keeps running in the background even though the main thread is exited. I tried to manually callSocketIOUnity.Disconnect() in OnApplicationQuit() and OnDestroy() to see if I could destroy the child thread, and it failed to do so. I thereby set SocketIOUnity.Options.Reconnection = false to stop auto-reconnection to the server and it worked (i.e. not attempting to reconnect to the server).

However, I am not sure if this can kill all background threads. Am I doing anything wrong? Is there any proper way to exit the main thread with all background threads killed?

Thanks again :)

I'm really glad you find the SocketIOUnity repository useful.

So for the Editor, I mentioned that i didn't tested, and I noticed that the behavior of the editor varies by unity version number, so don't count on it, check on pc or mobile devices. But these some of my suggestions / recommendation :

• Make sure you have one socket.io instance, do something like this (or be creative about it): May this link be helpful too: https://github.com/doghappy/socket.io-client-csharp/issues/151

  // inside SocketManager class
  public static SocketManager Instance { get; private set; } = null;
  public SocketIOUnity socket;
  private void Start()
  {
  InitInstance();
  }
  public void InitInstance(bool forceInit = false)
  {
  if (forceInit || Instance == null)
  {
      Debug.Log("InitInstance");
      Instance = this;
      socket = new SocketIOUnity("https://www.example.com");
      socket.OnUnityThread("spin", (res) =>
      {
          // TODO
      });
      socket.Connect();
      DontDestroyOnLoad(transform.root.gameObject);
  }
  }

• Pause socket receiving activity

  public handleSocketReceiving = true;
  void OnApplicationFocus(bool paused)
  {
  handleSocketReceiving = !paused;
  }
  void OnApplicationPause(bool paused)
  {
  handleSocketReceiving = !paused;
  }
  void OnApplicationQuit()
  {
  handleSocketReceiving = false;
  }
  // Somewhere
  socket.OnUnityThread("spin", (res) =>
  {
  if(handleSocketReceiving){
      //TODO
  }
  });

I hope these solve the problem.

Thank you very much for the advice. I will import your code snippets into my code.

So background threads can quit properly in a complied executable, right? Is it necessary to manually abort background threads with the code?

Thanks again :)

not necessary, if the app quite/exit, the background threads will also be terminated, unless you created and run the package on android or ios background service.

welcome :)
