You can use the

SessionObserver

class to track events related to an

ISession

of a specific

ISession.Type

. Use this class to get events when a session is created, is pending creation, or has failed to be created for a specific session type. It's possible to create an instance of this class independently of the

UnityServices

initialization, allowing independent systems in a project to track session-related events without handling the

Unity Services

and

MultiplayerService

states themselves.

The following code demonstrates this class's usage:


void OnAddingSessionStarted(AddingSessionOptions addingSessionOptions) {    Debug.Log($"A session of type {addingSessionOptions.Type} is being added.");}void OnSessionAdded(ISession session) {    Debug.Log($"A session of type {session.Type} has been added.");}void OnAddingSessionFailed(AddingSessionOptions addingSessionOptions, SessionException exception) {    Debug.Log($"The addition of a session of type {addingSessionOptions.Type} has failed with message {exception.Message}.");}// ...async Task CreateSession() {    async using (var sessionObserver = new SessionObserver("my-session-type")) {        sessionObserver.AddingSessionStarted += OnAddingSessionStarted;        sessionObserver.SessionAdded += OnSessionAdded;        sessionObserver.AddingSessionFailed += OnAddingSessionFailed;        var sessionOptions = new Sessionoptions(){            Type = "my-session-type"        }.WithRelayNetwork();        await Multiplayer.Instance.CreateSessionAsync(sessionOptions);    }}
