How to destroy lobby when load other scene?

Hello, I m working on my 1st multiplayer game, so I m really new with it.

I m developing game with only 2 scenes: Menu and Main scene. When user click Play button I load Main scene and start Lobby (if already exist any other lobby, then I m trying to join). But if user go back to Menu, I want to destroy Lobby at all, and player on other side should get OnClientDisconnectCallback.

Now I see - if player go back to Menu there is nothing happen. If any of players turn off gmae at all, then OnClientDisconnectCallback will handle, but not if other scene loaded. How I can do it properly?

For multiplayer I use UGS: Relay and Lobby

This is my code for init my LobbyManager:

Code (CSharp):

1.         private void Awake()
2.         {
3.             if (SceneManager.currentScene == SceneHelper.MENU)
4.             {
5.  
6.                 if (NetworkManager.Singleton != null)
7.                 {
8.                     NetworkManager.Singleton.Shutdown();
9.                     Destroy(NetworkManager.Singleton.gameObject);
10.                 }
11.  
12.                 return;
13.             }
14.          
15.             LobbyManager._instance = this;      
16.         }
17.         private async void Start()
18.         {
19.             if (SceneManager.currentScene != SceneHelper.MAIN)
20.                 return;
21.  
22.             // Initialize unity services
23.             await UnityServices.InitializeAsync();
24.  
25.             // Setup events listeners
26.             this.SetupEvents();
27.  
28.             // Unity Login
29.             await SignInAnonymouslyAsync();
30.  
31.             // Subscribe to NetworkManager events
32.             NetworkManager.Singleton.OnClientConnectedCallback += this.ClientConnected;
33.             NetworkManager.Singleton.OnClientDisconnectCallback += this.ClientDisconnected;
34.  
35.             this.FindMatch();
36.         }

 

Add a
private void OnDestroy()
{
.. call lobby shutdown code...
}

to one of the behaviors in your game scene.

 

Hi, this is my OnDestroy code:

Code (CSharp):

1. private async void OnDestroy()
2.         {
3.             // We need to delete the lobby when we're not using it
4.             Debug.Log("Destroying");
5.            
6.             NetworkManager.Singleton.Shutdown();
7.            
8.             string playerId = AuthenticationService.Instance.PlayerId;
9.             await LobbyService.Instance.RemovePlayerAsync(_lobbyId, playerId);
10.             await Lobbies.Instance.DeleteLobbyAsync(_lobbyId);
11.  
12.             AuthenticationService.Instance.SignOut();
13.         }

Unfortunately, still not working
