Advanced Sessions Plugin

HI.When using this plugin, I have a problem and can not solve it. I have a dedicated server, and when I try to open a session by CreatedAdvincedSession or simply call OpenLevel with dedicated server IP, I get the following message on the server “No game present to join for session advinced session”, but when the dedicated server is on the local machine, then there is no error and everything works correctly, the problem occurs only when the dedicated server is running on the remote machine. I would be grateful for any help.

I have noticed something very weird. Im using Advanced Sessions to get SteamAvatar, SteamName and SteamID and set those variables inside PlayerState. Then I can save all that and use it for Scoreboard list and NamePlate with Avatar and SteamNames. The thing is that SteamAvatar and SteamID fails. I finally got SteamID using my own C++ Class I found on Youtube and it works really fine but SteamAvatar still fails. I tried to get it using SlateBrush, Texture2D and UniqueNetID.

I keep trying things and have seen that Server can set and print a real NetUniqueID so I get the Avatar.
But when a client join the server, NetUniqueID in server and in new client change to ERROR: BAD UNIQUE NET ID and Avatar is not loaded.

What could be doing that ERROR BAD UNIQUE NET ID?

Awesome plugin thank you!

Its kind of hard to read that paragraph, but you can pull unique net ids out of the player state array that is replicated in, it takes a bit for the replication to complete so you need to check if it is valid yet before loading an avatar from the id in it.

Hey thanks for the response. The reason I think I do need to edit OnlineSessionAsyncServerSteam.cpp. Here’s a source that tells me I have to do that.

(Fyi i am doing a dedicated server)

what do you think about this? I’m pretty sure this is what’s needed to have your game show up when searching servers, and you need to do it to have your game match what you set your dedicated steam server’s name as… right?

You are talking about dedicated servers, my setup is for general servers, its pretty much an entirely different thing, but yes, for dedicated servers you should edit that to match your steam settings.

Unfortunately both muting and unregistering a remote player is not working, I can still hear people talking. Where is the best place to do such a thing? Right now I’m doing it in the GameState when game starts, on every single machine… Do I need to to something with Local User Num?

You shouldn’t no, not if there is only one, you do need to make sure that the UniqueNetID of the remote talker is valid though, if it hasn’t replicated in from the player array yet then it won’t do anything.

Are you not getting any console logs when you call it? You should be seeing one of the following log entries


        UE_LOG_ONLINE_VOICE(Log, TEXT("Muting remote talker (%s)"), *PlayerId.ToDebugString());
        UE_LOG_ONLINE_VOICE(Verbose, TEXT("Unknown remote talker (%s) specified to MuteRemoteTalker()"), *PlayerId.ToDebugString());
        UE_LOG_ONLINE_VOICE(Warning, TEXT("Invalid user specified in MuteRemoteTalker(%d)"), LocalUserNum);

You can add

DefaultEngine.ini


[Core.Log]
LogOnlineVoice=Verbose

To show the full log entries for it (IE: Unknown remote talker).

Even if the node returns True? Anyway I do this when the game starts, after player have slotted, when everything is fully replicated…

Unfortunately I don’t see in the console because for some reason Steam does not run in the editor, no matter what I do, even when I use a Standalone mode (I’m on 4.21 now). When I do a proper build, though, everything works (steam interface, inviting to game, voice chat). I need to enable the logs for shipped builds, try it out and come back to you.

Thank you for your help…

I’ll run some tests over the weekend to verify everything again, there were some changes to allow the Voip talker to work with steam but it shouldn’t have effected that any.

Hey, I’m currently troubling with getting a running connection with steam and some strange behaviour.
Setup:
UE4.19
2 PC
2 Steam Accounts (both in the same LAN)
Steam OSS enabled
The game is late join. The server is already within the game, client shall be able to join into the running game. Server is already in the correct map while client tries to connect from MainMenu.
Presence is set to false as that only seems to create a Lobby.

When opening a server from one PC, with LAN=false
CreateServerData.PNG
The client is able to find the server, but only when looking for LAN sessions (FindSessions LAN=true). The log also shows the LAN IP of the other computer for the found session. Trying to join that session, I only get a log spam of SetActiveLevelCollection attempted to use an out of date NetDriver: GameNetDriver until it finally times out and crashes.
The log originates from

UWorld::SetActiveLevelCollection


  
    ...
    GameState = ActiveLevelCollection->GetGameState();
    NetDriver = ActiveLevelCollection->GetNetDriver();
    DemoNetDriver = ActiveLevelCollection->GetDemoNetDriver();

    // TODO: START TEMP FIX FOR UE-42508
    if (NetDriver && NetDriver->NetDriverName != NAME_None)
    {
        UNetDriver* TempNetDriver = GEngine->FindNamedNetDriver(this, NetDriver->NetDriverName);
        if (TempNetDriver != NetDriver)
        {
            UE_LOG(LogWorld, Warning, TEXT("SetActiveLevelCollection attempted to use an out of date NetDriver: %s"), *(NetDriver->NetDriverName.ToString()));
            NetDriver = TempNetDriver;
        }
    }
    ...


The piece of code exchanges the NetDriver of the world, which seems to be an obvious issue when trying to use the SteamNetDriver to connect …

The config setup ( https://docs.unrealengine.com/en-us/…g/Online/Steam )



[/Script/Engine.GameEngine]
+NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemSteam.SteamNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")

[OnlineSubsystem]
DefaultPlatformService=Steam

[OnlineSubsystemSteam]
bEnableSteam=true
bEnabled=true
SteamAppID=924770
SteamDevAppId=924770
GameServerQueryPort=27015
bRelaunchInSteam=true
GameVersion=1.0.0.0
bVACEnabled=1
bAllowP2PPacketRelay=true
P2PConnectionTimeout=90

[/Script/OnlineSubsystemSteam.SteamNetDriver]
NetConnectionClassName="OnlineSubsystemSteam.SteamNetConnection"


Other scenario:
When disabling stuff in the config:



;    [/Script/Engine.GameEngine]
;    +NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemSteam.SteamNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")

[OnlineSubsystem]
DefaultPlatformService=Steam

[OnlineSubsystemSteam]
bEnableSteam=true
bEnabled=true
SteamAppID=924770
SteamDevAppId=924770
GameServerQueryPort=27015
bRelaunchInSteam=true
GameVersion=1.0.0.0
bVACEnabled=1
bAllowP2PPacketRelay=true
P2PConnectionTimeout=90

;   [/Script/OnlineSubsystemSteam.SteamNetDriver]
;   NetConnectionClassName="OnlineSubsystemSteam.SteamNetConnection"


The Internet server still displays as LAN. The client tries to connect, but fails and loads the MainMenu map again. Here is the client log of this scenario:

  • I found that steam requires seamless travel to be enabled in the GameMode, which is set to true. The game mode is set in the maps.
  • Trying to host a LAN game, the session does not even show up. Is it even possible to host a LAN game with steam as OSS?
  • Also tried to connect one PC to a different network with a devices that establishes a mobile network connection. Not able to find the session in this scenario.

You need to specify lan match in the level loading, not just listen

Thank you very much. I am not using VOIPTalker yet, I want to solve this before I start using it (the point being that I want to add walkie-talkie EQ on sound). Let me know if I can help.

thanks will try that.

The main question though would be why the online session does not work and why it shows up as LAN. It might show up as LAN as both computers are in the same network, but not sure about that.

No, I test most of my remote servers on steam across two local computers. From your post I had assumed that LAN was your goal, not the side effect?

LAN was just a side question. Having trouble with Online session that shows as LAN.

Well I have the perfect article to sort this out for you and it will explain far better (and with better formatting) than I can in here.

I really should have linked to it a long time ago as questions related to it keep popping up.

TL;DR though, turn on Presence on the session.

Ok fair enough I guess!

Is there anyone who knows how to check the mic of mine?
I can check which talker is speaking except me by is remote player talking.
However is local player talking with index 0 is not working.

Please help me nice guys!

Hello. I have one question. Does the UE4 network system allow creating sessions on in dedicated server on custom remote server(not Steam,Player host, etc.). I want connect to dedicated server which run on my remote PC(server) and create various sessions.That is, I want to run dedicated server on my remote computer and open sessions on it. Can I do this in one running instance of the dedicated server or will I have to launch a new dedicated server instance for each session. I looked at a lot of information but did not find an example of this , everywhere either creating a session as a player host, or an example of on Steam subsystem. I will be grateful for any lesson or tutorial related to this. As far as I understand, the Advanced Sessin plugin cannot help with this either, it creates sessions either as steam or as host.Thanks!!!
