So I am not exactly sure what I am doing wrong. I am trying to start up a dedicated server and connect multiple clients to it using .bat files but my clients aren’t connecting properly. I’m sure I’ve done something wrong, but again, the lack of documentation has left me clueless. The shooter example is less than helpful. Here is what I have. Hopefully someone can point out what I am missing.
Startup-Server.bat
“M:/UnrealEngine/Unreal Engine/4.6/Engine/Binaries/Win64/UE4Editor.exe” “M:/UnrealEngine/Projects/Alpha/Alpha.uproject” Startup -server -log -debug
Startup-Client.bat
“M:/UnrealEngine/Unreal Engine/4.6/Engine/Binaries/Win64/UE4Editor.exe” “M:/UnrealEngine/Projects/Alpha/Alpha.uproject” MainMenu -game -log -debug
My Startup is only ever loaded by the server and is used for server specific initialization then jumps to the Lobby map.
void AAlphaGameMode_Startup::InitGame(
const FString & MapName,
const FString & Options,
FString & ErrorMessage)
{
Super::InitGame(MapName, Options, ErrorMessage);
UAlphaGameInstance* agi = Cast<UAlphaGameInstance>(this->GetGameInstance());
if (agi && this->Role == ROLE_Authority)
{
agi->InitHost();
}
}
void AAlphaGameMode_Startup::BeginPlay()
{
UWorld* world = this->GetWorld();
if (world)
{
world->ServerTravel(FString("/Game/Maps/Lobby?listen"));
}
}
The client starts up in the MainMenu map where, currently, the user enters and ipaddress(127.0.0.1) to join the host. When the join button is pressed, this function is called.
void UAlphaGameInstance::ConnectToHostLobby(FString ipAddress)
{
UWorld* world = this->GetWorld();
if (world)
{
//This should work in theory...?
APlayerController* pc = UGameplayStatics::GetPlayerController(this, 0);
//UGameplayStatics::OpenLevel(world, FName(TEXT("Lobby")));
UE_LOG(AlphaGameInstance, Log, TEXT("ConnectToHostLobby >> Connecting to host."));
pc->ClientTravel(ipAddress, TRAVEL_Absolute);
}
}
My Lobby level blueprint is as follows:
And the Player count rep notify:
When I start the lobby from editor with 2 players, it works as expected but my Startup map is never loaded and the initialization is never done:
But if I start both server and then clients, the server does the startup map and initialization but the clients are never notified of the player count change:
Here is what the server logged when connecting with client:

I think what would be be most helpful is a tutorial or example strictly dedicated multiplayer networking. The shooter example is great but I can’t follow exactly what is going on because it’s so cluttered with everything else that I don’t understand.
