Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Child actor cannot set to hidden when run in standalone mode

I create a child actor component and spawn an actor. Everything seems perfect when I run in Editor mode. However, when I run in Standalone mode, the child actor is not hidden.

Below is part of my code:

.h

     UPROPERTY(VisibleAnywhere, BlueprintReadWrite, Category = "Drone")
     UChildActorComponent* DirectionChildActorComponent;
 
     UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "Drone")
     ADirectionActor* DirectionActor;

.cpp

 ADroneBase::ADroneBase()
 {
      // Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
     PrimaryActorTick.bCanEverTick = true;
 
     // Some other unrelated code here
 
     DirectionChildActorComponent = CreateDefaultSubobject<UChildActorComponent>(TEXT("DirectionActor"));
     DirectionChildActorComponent->SetupAttachment(RootComponent);
     DirectionChildActorComponent->SetRelativeLocation(FVector(0.0f, 0.0f, 0.0f));
     DirectionChildActorComponent->SetChildActorClass(ADirectionActor::StaticClass());
     DirectionChildActorComponent->CreateChildActor();
 }
 
 void ADroneBase::BeginPlay()
 {
     
     Super::BeginPlay();
 
     UDroneFunctionLibrary::ExecuteMiniSv();
 
     DirectionChildActorComponent->CreateChildActor();
     DirectionActor = (ADirectionActor*) DirectionChildActorComponent->GetChildActor();
     DirectionActor->SceneComponent->SetVisibility(false);
     DirectionActor->SetActorHiddenInGame(true);
 
     //Just for test, and result in "DirectionActor: DirectionActor_DirectionActor_CAT_0"
     GEngine->AddOnScreenDebugMessage(-1, 15.0f, FColor::Red, FString::Printf(TEXT("ADroneBase::BeginPlay(), DirectionActor: %s"), *DirectionActor->GetName()));

 }

What am I doing wrong in my code? Or is it a bug for UE4?

Thank you
