Widget update on Listen Server UE C++

Question

I'm actually trying to make a lobby system in C++ with Unreal, but actually I'm facing a huge problem.

My widget is updated with replication when a player hits the ready button that toggles if the widget displays ready or not. It works perfectly on clients but the widget still remains unchanged on the listen server.

void ALobbyGamemMode::UpdatePlayerInfo(APlayerController* RequstingPlayerController)
{
 if (!RequstingPlayerController) return;
 ALobbyPlayerController* LPC = Cast<ALobbyPlayerController>(RequstingPlayerController);
 if (!LPC) return;
 // Find the slot for the requesting player
 for (auto PS : PlayerSlots)
 {
 if (PS && PS->GetPC() == RequstingPlayerController)
 {
 // Create the updated player info
 FPLayerInfo NewInfo;
 if (RequstingPlayerController->PlayerState)
 {
 NewInfo = FPLayerInfo(RequstingPlayerController,
 FText::FromString(RequstingPlayerController->PlayerState->GetPlayerName()),
 LPC->GetPlayerInfo().bIsReady,
 RequstingPlayerController->PlayerState);
 }
 
 LPC->PlayerInfo = NewInfo;
 LPC->ForceNetUpdate();
 
 LPC->OnRep_PlayerInfo();
 
 // Update THIS player's character widget
 if (PS->GetSelectedCharacter())
 {
 PS->GetSelectedCharacter()->UpdatePlayerInfo(NewInfo);
 UE_LOG(LogTemp, Warning, TEXT("Updated character info for %s - Ready: %s"), 
 *RequstingPlayerController->GetName(), 
 NewInfo.bIsReady ? TEXT("Ready") : TEXT("Not Ready"));
 }
 // BROADCAST: Send this player's info to ALL OTHER PLAYERS
 for (auto OtherPC : Controllers)
 {
 if (OtherPC)
 {
 ALobbyPlayerController* OtherLPC = Cast<ALobbyPlayerController>(OtherPC);
 if (OtherLPC)
 {
 OtherLPC->Client_UpdateCharacterWidget(NewInfo);
 }
 }
 }
 if (ALobbyPlayerController* ServerLPC = Cast<ALobbyPlayerController>(RequstingPlayerController))
 {
 if (ServerLPC->IsLocalController()) // This is the server’s own controller
 {
 APawn* Pawn = ServerLPC->GetPawn();
 if (Pawn)
 {
 if (AThirdPersonneCharacter* CharPawn = Cast<AThirdPersonneCharacter>(LPC->GetPawn()))
 {
 CharPawn->SetPlayerInfo(NewInfo);
 };
 }
 }
 }
 CheckAllPlayersReady();
 break;
 }
 }
}

void AThirdPersonneCharacter::OnRep_PlayerInfo()
{
 if (!PlayerInfoWidgetComponent)
 {
 UE_LOG(LogTemp, Error, TEXT("PlayerInfoWidgetComponent is NULL on %s"), *GetName());
 return;
 }
 UUserWidget* Widget = PlayerInfoWidgetComponent->GetUserWidgetObject();
 UPlayerInfoWidget* InfoWidget = Cast<UPlayerInfoWidget>(Widget);
 if (InfoWidget)
 {
 InfoWidget->UpdatePlayerInfo(PlayerInfo);
 PlayerInfoWidgetComponent->SetVisibility(true);
 UE_LOG(LogTemp, Log, TEXT("Updated PlayerInfo on %s"), *GetName());
 }
 else
 {
 UE_LOG(LogTemp, Warning, TEXT("OnRep_PlayerInfo: Widget not yet created for %s"), *GetName());
 }
 
}

• zerocukor287: What is the type of PlayerSlots? Are you sure you not making a copy of the elements and modify those? I think you mean auto& in the for(auto PS: PlayerSlot) and for(auto OtherPC: Controllers)
