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: Connect socket in multiple pages doghappy/socket.io-client-csharp#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 :)
