Hook up the create, leave, and display session UI

In this tutorial, you will connect the UI to create a match session by using the MatchSessionDSWrapper_Starter class, which already incorporates the AGS Game SDK implementation. The CreateMatchSessionDSHandler_Starter class has been provided as a UI handler for this tutorial.

Open the CreateMatchSessionDSHandler_Starter.cs and add the code below:
```
private MatchSessionDSWrapper_Starter matchSessionDSWrapper;
```

You will use matchSessionDSWrapper.CreateMatchSession to create a match session. Go to the ClickDedicatedServerButton and replace the code with this:

public void ClickDedicatedServerButton()
{
    InGameMode selectedGameMode = InGameMode.None;
    GameSessionServerType selectedSessionServerType =
        TutorialModuleManager.Instance.IsModuleActive(TutorialType.MultiplayerDSEssentials) ?
        GameSessionServerType.DedicatedServerAMS :
        GameSessionServerType.DedicatedServer;

    MenuCanvas menu = MenuManager.Instance.GetCurrentMenu();
    if (menu is MatchSessionServerTypeSelection serverTypeSelection)
    {
        selectedGameMode = serverTypeSelection.SelectedGameMode;
        InitWrapper();
    }
    else
    {
        BytewarsLogger.LogWarning("Current menu is not server type selection menu while try to create match with DS");
        return;
    }

    matchSessionDSWrapper.CreateMatchSession(selectedGameMode, selectedSessionServerType);
    ShowLoading(
        "Creating Match Session (Dedicated Server)...",
        "Creating Match Session (Dedicated Server) is timed out.",
        createMatchSessionTimeoutSec,
        CancelCreateMatch);
}

Go to InitWrapper and implement the following code within the function:

private void InitWrapper()
{
    if (matchSessionDSWrapper == null)
    {
        matchSessionDSWrapper = TutorialModuleManager.Instance.GetModuleClass<MatchSessionDSWrapper_Starter>();
    }

    BindMatchSessionEvent();

    MatchSessionServerTypeSelection.OnBackButtonCalled -= OnBackButtonFromServerSelection;
    MatchSessionServerTypeSelection.OnBackButtonCalled += OnBackButtonFromServerSelection;
}

Now, set up the event binding in the BindMatchSessionEvent function along with the unbinding in UnbindMatchSessionEvent.

private void BindMatchSessionEvent()
{
    matchSessionDSWrapper.BindEvents();
    matchSessionDSWrapper.BindMatchSessionDSEvents();
    matchSessionDSWrapper.OnCreatedMatchSession += OnCreatedMatchSession;
    matchSessionDSWrapper.OnJoinedMatchSession += OnJoinedMatchSession;
    matchSessionDSWrapper.OnLeaveSessionCompleted += UnbindMatchSessionEvent;
}

private void UnbindMatchSessionEvent()
{
    matchSessionDSWrapper.UnbindEvents();
    matchSessionDSWrapper.UnbindMatchSessionDSEvents();
    matchSessionDSWrapper.OnCreatedMatchSession -= OnCreatedMatchSession;
    matchSessionDSWrapper.OnJoinedMatchSession -= OnJoinedMatchSession;
    matchSessionDSWrapper.OnLeaveSessionCompleted -= UnbindMatchSessionEvent;
}

OnCreatedMatchSession is responsible for updating the loading status and showing the cancel button. This button uses CancelCreateMatch as a callback. To be able to cancel matchmaking, update the CancelCreateMatch function with the code below.
```
private void CancelCreateMatch()
{
    Reset();
    ShowInfo("Match session creation cancelled");
    matchSessionDSWrapper.OnCreateMatchCancelled?.Invoke();
    matchSessionDSWrapper.CancelCreateMatchSession();
}
```

Play the game from the Unity editor. If successful, you will see this log:

 [MatchSessionWrapper.cs] [OnCreateSessionCompleted] [Log] [linenumber] - Successfully created the match session

Congratulations! You successfully connected the UI with the wrapper class to create a match session.
