I want to show a Loading Screen in all cases except to a dedicated server.

I was using this, but it return true if i’m a dedicated or listen server

GameInstance->IsDedicatedServerInstance();

Then i tried using this:


const APlayerController* PC = GameInstance-> GetFirstLocalPlayerController(GetWorld());
	if(IsValid(PC))
	{
		const ENetMode NetMode = PC->GetNetMode();	
		if( NetMode == ENetMode::NM_ListenServer) return true;
		if( NetMode == ENetMode::NM_DedicatedServer) return false;
	}
	return true;

But it does not works because the PlayerController has not been created yet… so it is null.

Is there any other way to know if am i a listen server?
Thank you so much!!

Your only option before the PlayerController is created could be to use the Engine TravelUrl and test it if it has the option “listen”.

Hi, thanks for your reply!!

Do you know how to get the right URL?
I tried these things but none of them is the right URL (they have not options, it is the map path only)

FURL URL = (GEngine && GetWorld()) ?  GEngine->LastURLFromWorld(GetWorld()) : FURL();
FURL URL = GetWorld() ?  GetWorld()->URL : FURL();
FURL URL = GetWorld() ?  GetWorld()->NextURL : FURL();
FURL URL = GetWorld() ?  GetWorld()->GetLocalURL() : FURL();

Thank you so much!!

It probably won’t work with this method while using Play In Editor mode unless if you start as Standalone and then create the Listen Server.
