Overlaps Not Firing Correctly

Development Programming & Scripting

Hey I am trying to detect the items in a cube. However, the overlap begin and overlap end function calls are not making sense.

Here is my cpp:

ALocationBox::ALocationBox()
{
 	// 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;
	Cube = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("mesh"));
	RootComponent = Cube;

	static ConstructorHelpers::FObjectFinder<UStaticMesh> BoxAsset(TEXT("/Game/StarterContent/Shapes/Shape_Cube"));

	if(BoxAsset.Succeeded()){
		Cube->SetStaticMesh(BoxAsset.Object);
		Cube->SetRelativeLocation(FVector(0.0f, 0.0f, 0.0f));
		Cube->SetWorldScale3D(FVector(1.f));
	}
	
	Cube->SetCollisionProfileName(TEXT("OverlapAll"));

	Cube->OnComponentBeginOverlap.AddDynamic(this, &ALocationBox::OnOverlapBegin); 
	Cube->OnComponentEndOverlap.AddDynamic(this, &ALocationBox::OnOverlapEnd);
}

//Overlap does not seem to be working judging from testing
void ALocationBox::OnOverlapBegin(class UPrimitiveComponent* OverlappedComp, class AActor* OtherActor, class UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)
{	
	if (OtherActor && (OtherActor != this) && OtherComp) 
	{
		UE_LOG(LogTemp, Error, TEXT("Began overlap with: %s"), *OtherActor->GetName());
	}
} 

void ALocationBox::OnOverlapEnd(class UPrimitiveComponent* OverlappedComp, class AActor* OtherActor, class UPrimitiveComponent* OtherComp, int32 OtherBodyIndex)
{
	if (OtherActor && (OtherActor != this) && OtherComp) 
	{
		UE_LOG(LogTemp, Error, TEXT("Ended overlap with: %s"), *OtherActor->GetName());
	}
}

I placed a peeler, cutting board, knife and coffer maker in the box. Here is the output:

[2020.03.27-05.17.26:600][426]LogTemp: Error: Ended overlap with: Board
[2020.03.27-05.17.26:600][426]LogTemp: Error: Ended overlap with: Board
[2020.03.27-05.17.26:600][426]LogTemp: Error: Ended overlap with: Knife
[2020.03.27-05.17.26:600][426]LogTemp: Error: Ended overlap with: Knife
[2020.03.27-05.17.26:600][426]LogTemp: Error: Ended overlap with: Knife
[2020.03.27-05.17.26:621][426]LogTemp: Error: Ended overlap with: Knife
[2020.03.27-05.17.26:622][426]LogTemp: Error: Ended overlap with: Peeler
[2020.03.27-05.17.26:622][426]LogTemp: Error: Ended overlap with: Peeler
[2020.03.27-05.17.26:622][426]LogTemp: Error: Ended overlap with: Peeler

No overlap began detection occurred. The items were never removed from the box.

Thanks in advance.

Overlap Begin only gets called if the item enters the collision area.

If you have already placed the items within the collision box in the level, Overlap Begin won’t get called.
