How to use publisher and subscriber codes in a same script in unity3d?

Hello ,

I am working with unity and I am trying to use both of the subscriber and publisher in a same unity file so to do that I did following solutions:

  1. I use publisher script and add it to my button and I use subscriber and add it to another Game object but unity crashed Because it wanted to run subscriber and publisher in every frame( that is in update method) with each other so it was impossible for unity.
  2. I made same script for publisher and subscriber like these 2 ways but it didn't work:

(My unity file try to publish the status of button and receive the status of real button from Arduino)

public class PUBSUB : MonoBehaviour

{

  public static string RedStatus;

  [SerializeFeild] private float threshold = 0.1f;

  [SerializeFeild] private float deadzone = 0.025f;

  public bool _isPressedRed;

  public Vector3 _stratPosRed;

  public ConfigurableJoint _jointRed;

  public UnityEvent onPressedRed, onReleasedRed;

  // Start is called before the first frame update

  void Start()

  {

    _stratPosRed = transform.localPosition;

    _jointRed = GetComponent<ConfigurableJoint>();

  }

  // Update is called once per frame

  void Update()

  {

    string host = "localhost";

    string username = "admin";

    string vpnname = "default";

    string password = "admin";

    if (!_isPressedRed && GetValueRed() + threshold >= 1)

      PressedRed();

    if (_isPressedRed && GetValueRed() - threshold <= 0)

      ReleasedRed();

    // Initialize Solace Systems Messaging API with logging to console at Warning level

    ContextFactoryProperties cfp = new ContextFactoryProperties()

    {

      SolClientLogLevel = SolLogLevel.Warning

    };

    cfp.LogToConsoleError();

    ContextFactory.Instance.Init(cfp);

    try

    {

      // Context must be created first

      using (IContext context = ContextFactory.Instance.CreateContext(new ContextProperties(), null))

      {

        // Create the application

        TopicPublisher topicPublisher = new TopicPublisher()         

        {

          VPNName = vpnname,

          UserName = username,

          Password = password

        };

        topicPublisher.Run(context, host);

      }

}

    catch (Exception ex)

    {

      Console.WriteLine("Exception thrown: {0}", ex.Message);

    }

    finally

    {

      // Dispose Solace Systems Messaging API

      ContextFactory.Instance.Cleanup();

    }

    Console.WriteLine("Finished.");

    Console.ReadLine();

    ContextFactoryProperties cfp1 = new ContextFactoryProperties()

    {

      SolClientLogLevel = SolLogLevel.Warning

    };

    cfp1.LogToConsoleError();

    ContextFactory.Instance.Init(cfp1);

    try

    {

     using (IContext context1 = ContextFactory.Instance.CreateContext(new ContextProperties(), null))

      {

       using (TopicSubscriber topicSubscriber = new TopicSubscriber()

        {

          VPNName = vpnname,

          UserName = username,

          Password = password

        })

        {

          // Run the application within the context and against the host

          topicSubscriber.RunSUB(context1, host);

        }

      }

  }

    catch (Exception ex)

    {

      Console.WriteLine("Exception thrown: {0}", ex.Message);

    }

    finally

    {

       ContextFactory.Instance.Cleanup();

    }

    Console.WriteLine("Finished."); 

  }

  IEnumerator Wait()

  {

    yield return new WaitForSeconds(5);

  }

  public float GetValueRed()

  {

    var value = Vector3.Distance(_stratPosRed, transform.localPosition) / _jointRed.linearLimit.limit;

    if (System.Math.Abs(value) < deadzone)

      value = 0;

    return Mathf.Clamp(value, min: -1f, max: 1f);

  }

  public void PressedRed()

  {

    _isPressedRed = true;

    onPressedRed.Invoke();

    // Re = "Pressed Red Buttom";

    RedStatus = "1";

    Debug.Log(message: RedStatus);

  }

  public void ReleasedRed()

  {

    _isPressedRed = false;

    onReleasedRed.Invoke();

    // Debug.Log(message: "Released Red Buttom");

    RedStatus = "0";

    Debug.Log(message: RedStatus);

  }

    Actually in the above script I ContextFactory.Instance.Init(cfp) for publisher and run it with topicPublisher.Run(context, host) and for subscriber I use ContextFactory.Instance.Init(cfp1)

    and topicSubscriber.RunSUB(context1, host) But it didnt work.

    Also in another attempt I run this code:

    public class PUBSUB : MonoBehaviour

    {

     public static string RedStatus;

     [SerializeFeild] private float threshold = 0.1f;

     [SerializeFeild] private float deadzone = 0.025f;

     public bool _isPressedRed;

     public Vector3 _stratPosRed;

     public ConfigurableJoint _jointRed;

     public UnityEvent onPressedRed, onReleasedRed;

     void Start()

     {

      _stratPosRed = transform.localPosition;

      _jointRed = GetComponent<ConfigurableJoint>();

     }

    void Update()

     {

      string host = "localhost";

      string username = "admin";

      string vpnname = "default";

      string password = "admin";

      if (!_isPressedRed && GetValueRed() + threshold >= 1)

       PressedRed();

      if (_isPressedRed && GetValueRed() - threshold <= 0)

       ReleasedRed();

      ContextFactoryProperties cfp = new ContextFactoryProperties()

      {

       SolClientLogLevel = SolLogLevel.Warning

      };

      cfp.LogToConsoleError();

      ContextFactory.Instance.Init(cfp);

      try

      {

       using (IContext context = ContextFactory.Instance.CreateContext(new ContextProperties(), null))

       {

         TopicPublisher topicPublisher = new TopicPublisher()     

        {

         VPNName = vpnname,

        UserName = username,

         Password = password

        };

        topicPublisher.Run(context, host);

       }

      using (IContext context = ContextFactory.Instance.CreateContext(new ContextProperties(), null))

       {

        TopicSubscriber topicSubscriber = new TopicSubscriber()

        {

         VPNName = vpnname,

         UserName = username,

         Password = password

        };

        topicSubscriber.Run(context, host);

        }

    }

    catch (Exception ex)

      {

       Console.WriteLine("Exception thrown: {0}", ex.Message);

      }

      finally

      {

        ContextFactory.Instance.Cleanup();

      }

      Console.WriteLine("Finished.");

      Console.ReadLine(); ...

    And then I used other methods like previous script actually I run publisher and subscriber with the same cfp and same context But it didnt work.

    I should mention that I can run subscriber and publisher in two different unity file andeach of them individually works and I can publish to solace Broker and receive from it now I need to run them with each other.

    My publisher code is :

    public class RedButton : MonoBehaviour

    {

      public static string Re;

     [SerializeFeild] private float threshold = 0.1f;

     [SerializeFeild] private float deadzone = 0.025f;

     private bool _isPressedRed;

     private Vector3 _stratPosRed;

     private ConfigurableJoint _jointRed;

     public UnityEvent onPressedRed, onReleasedRed;

     void Start()

     {

      _stratPosRed = transform.localPosition;

      _jointRed = GetComponent<ConfigurableJoint>();

     }

     void Update()

     {

       string host = "localhost";

       string username = "admin";

       string vpnname = "default";

       string password = "admin";

       if (!_isPressedRed && GetValueRed() + threshold >= 1)

        PressedRed();

    (_isPressedRed && GetValueRed() - threshold <= 0)

        ReleasedRed();

       ContextFactoryProperties cfp = new ContextFactoryProperties()

       {

        SolClientLogLevel = SolLogLevel.Warning

       };

       cfp.LogToConsoleError();

       ContextFactory.Instance.Init(cfp);

       try

       {

        using (IContext context = ContextFactory.Instance.CreateContext(new ContextProperties(), null))

        {

         TopicPublisher topicPublisher = new TopicPublisher()

         {

          VPNName = vpnname,

          UserName = username,

          Password = password

         };

         topicPublisher.Run(context, host);

        }

       }

       catch (Exception ex)

       {

        Console.WriteLine("Exception thrown: {0}", ex.Message);

       }

       finally

       {

         ContextFactory.Instance.Cleanup();

       }

       Console.WriteLine("Finished.");

       Console.ReadLine();

     }

     IEnumerator Wait()

     {

       yield return new WaitForSeconds(5);

     }

    My publisher and subscriber scripts are made from Solace Github...


    Now ,I should run both of them is a same script in a same unity file, I would apricated it If someone can help me ?
