Hi, assume that I have created a Steam lobby using Sessions->CreateSession().

How can I get the lobby id (CSteamID)?

Now, others players joins to this session using Sessions->JoinSession().

How can I get a list of members of this lobby?

Something like this with your unique session name. Note that you may have to manually register players, eg in Epic Online Subsystem lobbies auto reigster players and sessions don’t, not sure about steam.


TArray<FUniqueNetIdRepl> UECRGameInstance::GetPartyMembersList(bool bForClient)
{
	TArray<FUniqueNetIdRepl> Result;
	if (OnlineSubsystem)
	{
		if (const IOnlineIdentityPtr Identity = OnlineSubsystem->GetIdentityInterface())
		{
			if (IOnlineSessionPtr SessionInterface = OnlineSubsystem->GetSessionInterface())
			{
				FNamedOnlineSession* NamedOnlineSession = SessionInterface->GetNamedSession(
					bForClient ? PARTY_LOBBY_CLIENT_SESSION_NAME : PARTY_LOBBY_SESSION_NAME);
				if (NamedOnlineSession)
				{
					for (TSharedRef<FUniqueNetId const, ESPMode::ThreadSafe> Member : NamedOnlineSession->
					     RegisteredPlayers)
					{
						Result.Add(Member);
					}
				}
			}
		}
	}
	return Result;
}

This is for list of players, there is also a stuct MemberSettings in SessionSettings which stores custom member attributes (eg you can set for member whether he is ready or not there)
