Advanced Steam Sessions - Online State is empty

Akacz47 · May 28, 2024, 12:57am

Hi, I have a problem to check my friends online status using Advanced Steam Sessions. I can host and join to my friends but when I try to check their online status, it seems like it was empty (I have tried to print this and when I remove “Switch on EBPOnlinePresenceState” everything works fine).

Steam overlay is active, I’m using test steam app id, I have copied this into DefaultEngine.ini:

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

[OnlineSubsystem]
DefaultPlatformService=Steam

[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=480

; If using Sessions
; bInitServerOnClient=true

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

I have active plugins like: Advanced Steam Sessions, Advanced Sessions, Online Subsystem, Online Subsystem Steam

It happeds only when I build and package my project to .exe file. In editor everything works fine.

This is how I did it in my game, and it worked quite fine. You can try it in your C++.

void UEosHelper::GetFriendInfoFromList(const int32 LocalPlayerId, const FString& UniqueNetId)
{
	if (OnlineSubsystem)
	{
		const IOnlineFriendsPtr FriendsInterface = OnlineSubsystem->GetFriendsInterface();
		const TSharedPtr<const FUniqueNetId> NetId = CreateUniqueIdFromString(UniqueNetId);
		if (FriendsInterface != nullptr && FriendsInterface.IsValid() && NetId.IsValid())
		{
			const TSharedPtr<FOnlineFriend> Friend = FriendsInterface->GetFriend(LocalPlayerId, *NetId, FriendListName);

			const bool IsPlayingTheSameGame = Friend->GetPresence().bIsPlayingThisGame;
			const FOnlineUserPresenceStatus OnlineStatus = Friend->GetPresence().Status;
			switch (OnlineStatus.State)
			{
			case EOnlinePresenceState::Away:
				break;
			case EOnlinePresenceState::Chat:
				break;
			case EOnlinePresenceState::Offline:
				break;
			case EOnlinePresenceState::Online:
				break;
			case EOnlinePresenceState::ExtendedAway:
				break;
			case EOnlinePresenceState::DoNotDisturb:
				break;
				default: {}
			}
		}
	}
}

You can now create your own struct to handle return value, and here is how it is in my game.

.h file

USTRUCT(BlueprintType)
struct FFriendListInfo
{
	GENERATED_USTRUCT_BODY()
	
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	EFriendOnlineStatus PlayerOnlineState;

	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	bool PlayingSameGame;	
};

UENUM(BlueprintType)
enum class EFriendOnlineStatus : uint8
{
	Online,
	Offline,
	Away,
	ExtendedAway,
	DoNotDisturb,
	Chat,
	Unknown
};

UFUNCTION(BlueprintPure)
	FFriendListInfo GetFriendInfoFromList(const int32 LocalPlayerId, const FString& UniqueNetId);

.cpp

FFriendListInfo UEosHelper::GetFriendInfoFromList(const int32 LocalPlayerId, const FString& UniqueNetId)
{
	if (OnlineSubsystem)
	{
		const IOnlineFriendsPtr FriendsInterface = OnlineSubsystem->GetFriendsInterface();
		const TSharedPtr<const FUniqueNetId> NetId = CreateUniqueIdFromString(UniqueNetId);
		if (FriendsInterface != nullptr && FriendsInterface.IsValid() && NetId.IsValid())
		{
			const TSharedPtr<FOnlineFriend> Friend = FriendsInterface->GetFriend(LocalPlayerId, *NetId, FriendListName);

			const bool IsPlayingTheSameGame = Friend->GetPresence().bIsPlayingThisGame;
			const FOnlineUserPresenceStatus OnlineStatus = Friend->GetPresence().Status;
			EFriendOnlineStatus ConvertedStatus;
			switch (OnlineStatus.State)
			{
			case EOnlinePresenceState::Away:
				ConvertedStatus = EFriendOnlineStatus::Away;
				break;
			case EOnlinePresenceState::Chat:
				ConvertedStatus = EFriendOnlineStatus::Chat;
				break;
			case EOnlinePresenceState::Offline:
				ConvertedStatus = EFriendOnlineStatus::Offline;
				break;
			case EOnlinePresenceState::Online:
				ConvertedStatus = EFriendOnlineStatus::Online;
				break;
			case EOnlinePresenceState::ExtendedAway:
				ConvertedStatus = EFriendOnlineStatus::ExtendedAway;
				break;
			case EOnlinePresenceState::DoNotDisturb:
				ConvertedStatus = EFriendOnlineStatus::DoNotDisturb;
				break;
				default:
					ConvertedStatus = EFriendOnlineStatus::Unknown;
			}

			FFriendListInfo FriendListInfo;
			FriendListInfo.PlayerOnlineState = ConvertedStatus;
			FriendListInfo.PlayingSameGame = IsPlayingTheSameGame;
			return FriendListInfo;
		}
	}

	FFriendListInfo FriendListInfo;
	FriendListInfo.PlayerOnlineState = EFriendOnlineStatus::Unknown;
	FriendListInfo.PlayingSameGame = false;
	return FriendListInfo;
}

I don’t get any errors and I use UE version 5.4.1

You need to tell me what is the crash, so that I can help.

Akacz47 · May 28, 2024, 10:13pm

Ok, I tried to make it simple and figure it out what is the problem. I have an idea to just get a friend instance and return true if he’s Online. However I can’t include AdvancedFriendsLibrary.h in .h files, but in .cpp files it is possible.

I get an error: Unable to find ‘class’, ‘delegate’, ‘enum’, or ‘struct’ with name ‘FOnlineFriend’

and this warning:

Multiplayer.uproject does not list plugin ‘OnlineSubsystemSteam’ as a dependency, but module ‘Multiplayer’ depends on ‘OnlineSubsystemSteam’.

I have a simple class:
MyBlueprintFunctionLibrary.h

#pragma once

#include "CoreMinimal.h"
#include "Kismet/BlueprintFunctionLibrary.h"

#include "AdvancedFriendsLibrary.h" //<--- this cannot be included for some reason
#include "MyBlueprintFunctionLibrary.generated.h"

UCLASS()
class MULTIPLAYER_API UMyBlueprintFunctionLibrary : public UBlueprintFunctionLibrary
{
	GENERATED_BODY()

public:
    UFUNCTION(BlueprintCallable, Category = "Online|Presence")
    static bool GetFriendPresenceStatus(const FOnlineFriend& Friend);
};

MyBlueprintFunctionLibrary.cpp

#include "MyBlueprintFunctionLibrary.h"

bool UMyBlueprintFunctionLibrary::GetFriendPresenceStatus(const FOnlineFriend& Friend)
{
	const FOnlineUserPresenceStatus OnlineStatus = Friend.GetPresence().Status;
	switch (OnlineStatus.State)
	{
	case EOnlinePresenceState::Online:
		return true;
	}
	return false;
}

My .Build.cs file:

using UnrealBuildTool;

public class Multiplayer : ModuleRules
{
	public Multiplayer(ReadOnlyTargetRules Target) : base(Target)
	{
		PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;

		PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "EnhancedInput" , "AdvancedSessions", "AdvancedSteamSessions" });

		PrivateDependencyModuleNames.AddRange(new string[] { "OnlineSubsystem", "OnlineSubsystemNull", "OnlineSubsystemSteam"});
	}
}

.Target.cs

using UnrealBuildTool;
using System.Collections.Generic;

public class MultiplayerTarget : TargetRules
{
	public MultiplayerTarget(TargetInfo Target) : base(Target)
	{
		Type = TargetType.Game;
		DefaultBuildSettings = BuildSettingsVersion.V5;
		IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_4;
		
		bUsesSteam = true;

		ExtraModuleNames.Add("Multiplayer");
	}
}

I also copied OnlineSubsystemSteam into my plugins folder and rebuild an entire project.

Let me know if you need more information.

EDIT:
I changed code to use # include AdvancedFriendsLibrary.h just in .cpp file, removed warning by adding to my .uproject:

{
		"Name": "OnlineSubsystemSteam",
		"Enabled": true
}

But I get unknown function error:

This is a typical Null pointer exception. Check your MyBlueprintFunctionLibrary and line 71. This is whre it happens.

Bojann · May 30, 2024, 10:34am

Also, can you take a look at this video?

Maybe you are doing it too early. You need to wait for login to complete in order to request friends list. There is much more to cover there.

Akacz47 · May 30, 2024, 3:39pm

I get this error when I try to get online status in switch statement

const FOnlineUserPresenceStatus OnlineStatus = Friend.GetPresence().Status; // OK

switch (OnlineStatus.State) //CRASH
{
    case EOnlinePresenceState::Online:
    return true;
}

I don’t need to login in advanced steam sessions, I have to only create a session (as far I know). I watched this and previous tutorials but I don’t even have these data for login in steam.

It happends only when I try to build project. In standalone everything works.

Bojann · May 30, 2024, 3:43pm

You don’t need to login to Advanced Sessions, but you cannot ask fro friends list if Online Subsystem is not initialized and if you are not yet logged in.

I use this code to check when I’m logged in (my class is UEosHelper)

		const IOnlineIdentityPtr Identity = OnlineSubsystem->GetIdentityInterface();
				
		if (Identity != nullptr)
		{
			Identity->OnLoginCompleteDelegates->AddUObject(this, &UEosHelper::OnLoginComplete);
			Identity->AutoLogin(0);
		}

function

void UEosHelper::OnLoginComplete(int32 LocalPlayerNum, bool Success, const FUniqueNetId& ID, const FString& Message)

Then you can request friends list. In your case OnlineStatus is null and therefore you get NPE.

Bojann · May 30, 2024, 3:51pm

Btw, I am not sure if this could be the issue for you, buuuut, I remember I had to request user info before requesting any info. So after I log in I do this:

void USteamHelper::RequestFriendsInfo(const FString& UniqueNetId)
{
	if (SteamAPI_Init())
	{
		const uint64 Int64Id = FCString::Atoi64(*UniqueNetId);
		SteamFriends()->RequestUserInformation(Int64Id, false);
	}
}

For this you must have Steam_API. But again, I think you should watch the video I gave you, and try to go from scratch.

You need to add Steam SDK for this, but again. If you would just watch some videos online, like the one I sent above, you might resolve this issue without having to use Steam_API. I can’t tell from forums what migth go wrong, and sometimes it just pays off to start from scratch. There are many videos online that can help.

The only solution I see is to simply add block “on invite accept” in blueprints. After that invite someone by steam overlay (shift + tab shortcut). Thank you for your efforts, I really appreciate it

No problem. I hope you resolve it.
