How to create a session

1. Get UScriptSessionSubsystem subsystem, and bind events

SessionSubsystem = UScriptSessionSubsystem::Get();

if (SessionSubsystem != nullptr)
{
    SessionSubsystem.OnCreateSessionCompleteEvent.AddUFunction(this, n"OnCreateSession");
    SessionSubsystem.OnFindSessionsCompleteEvent.AddUFunction(this, n"OnFindSession");
}

2. Having two buttons for hosting and joining
3. On Host button click, call CreateSession function.

if (System::IsValid(SessionSubsystem))
{
    SessionSubsystem.CreateSession(NumPublicConnections, false);
}

4. In the OnCreateSession function, call ServerTravel to load the map and listen for the other client to join.

UFUNCTION()
private void OnCreateSession(bool bSuccessful)
{
    FString MapName = "ThirdPersonMap?listen";

    if (bSuccessful)
    {
        GetWorld().ServerTravel(MapName, true, false);
    }
    else
    {
        Log("Failed to create session!");
    }
}

How to find a session and join

1. On the Join button click, call FindSessions

if (System::IsValid(SessionSubsystem))
{
    SessionSubsystem.FindSessions(100, false);
}

2. In the OnFindSession function, iterate through SessionResults sessions, then join the active session.
   • p.s. You can implement a listbox that includes all the sessions for the user to choose from.

UFUNCTION()
private void OnFindSession(const TArray<FScriptSessionResult>&in SessionResults, bool bWasSuccessful)
{
    if (System::IsValid(SessionSubsystem))
    {
        for (auto Result : SessionResults)
        {
            SessionSubsystem.JoinGameSession(Result);
            return;
        }
    }

    if (!bWasSuccessful || SessionResults.Num() == 0)
    {
        Log("Failed to find session!");
    }
}
