Why does bVisible cause an error for me?

Hey all,

I am doing an Unreal project for school, but I am having trouble getting it to work properly. I have tried looking it up online to solve the problem myself, which for the most part I did, but I am still getting an inaccessible error for bVisible and I cannot figure out why.

.cpp code

#include "J_Ercolano_GAM312.h"
#include "LightSwitchCodeOnly.h"
#include "Components/PointLightComponent.h"

#include "DrawDebugHelpers.h"

// Sets default values
ALightSwitchCodeOnly::ALightSwitchCodeOnly()
{
 	// 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;

	DesiredIntensity = 3000.0f;
	
	PointLight1 = CreateDefaultSubobject<UPointLightComponent>(TEXT("PointLight1"));
	PointLight1->Intensity = DesiredIntensity;
	PointLight1->bVisible = true;
	RootComponent = PointLight1;

	Sphere1 = CreateDefaultSubobject<USphereComponent>(TEXT("Sphere1"));
	Sphere1->InitSphereRadius(250.0f);
	Sphere1->SetCollisionProfileName(TEXT("Trigger"));
	Sphere1->SetupAttachment(RootComponent);

	Sphere1->OnComponentBeginOverlap.AddDynamic(this, &ALightSwitchCodeOnly::OnOverlapBegin);       // set up a notification for when this component overlaps something
	Sphere1->OnComponentEndOverlap.AddDynamic(this, &ALightSwitchCodeOnly::OnOverlapEnd);       // set up a notification for when this component overlaps something
}

// Called when the game starts or when spawned
void ALightSwitchCodeOnly::BeginPlay()
{
	Super::BeginPlay();
	
}

// Called every frame
void ALightSwitchCodeOnly::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);

}

void ALightSwitchCodeOnly::OnOverlapBegin(class UPrimitiveComponent* OverlappedComp, class AActor* OtherActor, class UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)
{
	if (OtherActor && (OtherActor != this) && OtherComp)
	{
		ToggleLight();
	}
}

void ALightSwitchCodeOnly::OnOverlapEnd(class UPrimitiveComponent* OverlappedComp, class AActor* OtherActor, class UPrimitiveComponent* OtherComp, int32 OtherBodyIndex)
{
	if (OtherActor && (OtherActor != this) && OtherComp)

I cannot for the life of me figure this out. The error reads “member ‘USceneComponent::bVisible’ (declared at line 199 of [bunch of locations]SceneComponent.h’) is inaccessible”. I went to the Scene Component and it doesn’t want me to edit anything without prompting me about what I am doing. I have been trying to fix the problem for a while now and I am getting nowhere. It would be nice to hear exactly what this is because I don’t know that. Thanks a million for the help!

That is the error you get when something is in a scope you don’t have access to. In this case bVisible is a private member of USceneComponent, so you’re not allowed to just set it directly from your Actor.

You can modify it by calling SetVisibleFlag instead.

I did something similar. SetVisibility or something to that affect.

How would you DO that I have the same problem!
