Put it all together - Introduction to Session - (Unity module)

Connect the UI to create and leave a session

Open the SessionMenuHandler_Starter.cs file and add the following code:
```
private SessionEssentialsWrapper_Starter sessionEssentialsWrapper;
```

Add the following line to the Awake() function:

private void Awake()
{
    sessionEssentialsWrapper = TutorialModuleManager.Instance.GetModuleClass<SessionEssentialsWrapper_Starter>();
    ...
}

Create new functions to bind and unbind the events from sessionEssentialsWrapper:

 private void SubcsribeSessionEvents()
 {
     sessionEssentialsWrapper.OnCreateSessionCompleteEvent += OnCreateSessionCompleted;
     sessionEssentialsWrapper.OnLeaveSessionCompleteEvent += OnLeaveSessionCompleted;
 }

private void UnSubscribeSessionEvents()
{
    sessionEssentialsWrapper.OnCreateSessionCompleteEvent -= OnCreateSessionCompleted;
    sessionEssentialsWrapper.OnLeaveSessionCompleteEvent -= OnLeaveSessionCompleted;
}

In the Start function, add the following code:

 if (sessionEssentialsWrapper == null)
 {
     sessionEssentialsWrapper = TutorialModuleManager.Instance.GetModuleClass<SessionEssentialsWrapper_Starter>();
     SubscribeSessionEvents();
 }

Go to the OnEnable() function and update the code as follows:

private void OnEnable()
{
    CurrentView = SessionMenuView.Default;
    if (sessionEssentialsWrapper == null)
    {
        return;
    }
    
    SubscribeSessionEvents();
}

Navigate to the OnDisable() function and unsubscribe from the events with the following:

private void OnDisable()
{
    if (sessionEssentialsWrapper == null)
    {
        return;
    }

    UnSubscribeSessionEvents();
}

Update the OnEliminationButtonClicked() function. You need to define a variable to hold the value for SessionV2GameSessionCreateRequest, which will be passed to sessionEssentialsWrapper.CreateSession. The code below uses unity-elimination-none as the match pool which we can get from the GameSessionConfig class. The final code for this function will appear as follows:

private void OnEliminationButtonClicked()
{
    Dictionary<InGameMode, 
        Dictionary<GameSessionServerType, 
            SessionV2GameSessionCreateRequest>> sessionConfig = GameSessionConfig.SessionCreateRequest;
    
    if (!sessionConfig.TryGetValue(InGameMode.None, out var matchTypeDict))
    {
        BytewarsLogger.LogWarning("InGame Mode Not found");
        return;
    }

    if (!matchTypeDict.TryGetValue(GameSessionServerType.None, out var request))
    {
        BytewarsLogger.LogWarning("GameSessionServerType Not found");
        return;
    }

    CurrentView = SessionMenuView.Creating;
    Button button = creatingPanel.gameObject.GetComponentInChildren<Button>();
    button.gameObject.SetActive(true);
    sessionEssentialsWrapper.CreateSession(request);
}

In the OnLeaveSessionButtonClicked() function, you will implement logic to leave a session. Replace the existing implementation with the code below:
```
private void OnLeaveSessionButtonClicked()
{
    sessionEssentialsWrapper.LeaveSession(cachedSessionId);
}
```

Update the functions that are declared as the event listeners. There are two functions: OnCreateSessionCompleted() and OnLeaveSessionCompleted().

private void OnCreateSessionCompleted(Result<SessionV2GameSession> result)
{
    if (!result.IsError)
    {
        CurrentView = SessionMenuView.Joining;
        StartCoroutine(DelayCallback(sessionView => Helper(result, sessionView)));
    }
    else
    {
        CurrentView = SessionMenuView.Failed;
    }
}

private void OnLeaveSessionCompleted(Result<SessionV2GameSession> result)
{
    if (!result.IsError)
    {
        MenuManager.Instance.OnBackPressed();
    } 
    else
    {
        BytewarsLogger.LogWarning($"{result.Error.Message}");
        MenuManager.Instance.OnBackPressed();
    }
}

Creating a session will automatically join the session, so DelayCallback has been added as the delay to show the message from creating a session panel to joining a session, and then join the session.
