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"

UBoxComponent in UStaticMeshComponent and could not save map because Graph is linked to private object

Hi,

I have problem. I'm getting erorr when saving map:

Can't save ../../../../../Documents/Unreal Projects/AAAxCaveMaster/Content/Maps/Map101.umap: Graph is linked to private object(s) in an external package.
External Object(s):
@BoxComponent

Problem is with pointer to UBoxComponent in UStaticMeshComponent (UTileStaticMeshComponent).
Basiclly TileStaticMeshComponent is same as UStaticMeshComponent.
TileStaticMeshComponent is used in Actor Object.

Below code TileStaticMeshComponent.h

 UCLASS()
 class AAAXCAVEMASTER_API UTileStaticMeshComponent : public UStaticMeshComponent
 {
     GENERATED_BODY()
 
 protected:
 
     UPROPERTY()
     UBoxComponent* BoxComponent;  // PROBLEM ////////////////////////////////////
 public:
 
     UTileStaticMeshComponent( const FObjectInitializer& ObjectInitializer );
 }

Below code TileStaticMeshComponent.cpp

 UTileStaticMeshComponent::UTileStaticMeshComponent(const FObjectInitializer& ObjectInitializer )
 {
     UBoxComponent* BoxPtr = CreateDefaultSubobject<UBoxComponent>( Name_BoxComponent );
     BoxPtr->SetBoxExtent( FVector(1.f, 1.f, 1.f) );
     BoxPtr->SetupAttachment( this );
     BoxComponent = BoxPtr; // PROBLEM ////////////////////////////////////////////
 }

Try it with NewObject(this)

Yeah, I moved BoxPtr/BoxComponent initialization from constructor to UTileStaticMeshComponent::BeginPlay and used NewObject instade of CreateDefaultSubobject.
This is working now, but maybe You know why? I mean what is wrong with earlier solution. What I don't understand.
