Problem with construction script

Development Programming & Scripting
1

Hi everyone!
I have a some little problem here. This is my code:

.h

UCLASS()
class PROJECTONE_API AHexGrid : public AActor
{
	GENERATED_BODY()
	
public:	

	AHexGrid();

	UPROPERTY(VisibleAnywhere, BlueprintReadOnly)
		class USceneComponent* GridSystem;
	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "GridSettinds")
		class UHexSpriteComponent* Hex;

	// Called when the game starts or when spawned
	virtual void BeginPlay() override;
	
	// Called every frame
	virtual void Tick( float DeltaSeconds ) override;

	//Construct script
	virtual void OnConstruction(const FTransform& Transform) override;

	
	
};

.cpp

void AHexGrid::OnConstruction(const FTransform & Transform)
{
	Super::OnConstruction( Transform );

	//Hex = ConstructObject<UHexSpriteComponent>(UHexSpriteComponent::StaticClass(), this, TEXT("Name1"));
	Hex = NewObject<UHexSpriteComponent>(this, UHexSpriteComponent::StaticClass(), TEXT("Comp_1"));
	Hex->RegisterComponent();
	Hex->AttachToComponent(GridSystem, FAttachmentTransformRules::KeepWorldTransform);
}

This component added in actor, but I cant modify his setting:

Whats wrong? Maybe I miss something?

P.S.

If I add this component from here:

AHexGrid::AHexGrid()
{
 	// 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;

	GridSystem = CreateDefaultSubobject<USceneComponent>(TEXT("HexGrid"));
	GridSystem->AttachToComponent(GetRootComponent(), FAttachmentTransformRules::KeepWorldTransform);
	Hex = NewObject<UHexSpriteComponent>(this, UHexSpriteComponent::StaticClass(), TEXT("Comp_1"));
	Hex->RegisterComponent();
	Hex->AttachToComponent(GridSystem, FAttachmentTransformRules::KeepWorldTransform);

}

I can use his settings.

AHexGrid::AHexGrid() is your actual constructor. The editor will only let you modify objects created within the constructor; these are “native”. That’s what the warning in the image you posted means: “Native components are editable when declared as UPROPERTY in C++”.

Anything created outside the constructor is a dynamically created object and cannot be modified in the details panel of the blueprint.

OnConstruction is not your constructor script; it’s an event called when construction is complete.

Create your components in the constructor and you should be fine.

You also might want to consider using CreateDefaultSubobject or CreateOptionalDefaultSubobject rather than NewObject within the constructor.

Hmm, it’s clear now. Thanks for help!
