Hi,

Anyone that have an idea whats wrong with this code? the TriggerEnter is never called when my player is trying to pickup the object.

Thanks

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

	PickUpRoot = CreateDefaultSubobject<USceneComponent>(TEXT("Pickup root"));
	RootComponent = PickUpRoot;

	PickUpMesh = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("Pickup mesh"));
	PickUpMesh->AttachToComponent(PickUpRoot,FAttachmentTransformRules::SnapToTargetNotIncludingScale);

	PickUpBox = CreateDefaultSubobject<UBoxComponent>(TEXT("PickupBox"));
	PickUpBox->SetWorldScale3D(FVector(1.0f, 1.0f, 1.0f));
	PickUpBox->bGenerateOverlapEvents = true;
	PickUpBox->OnComponentBeginOverlap.AddDynamic(this, &APickup::TriggerEnter);
	PickUpBox->AttachToComponent(PickUpRoot, FAttachmentTransformRules::SnapToTargetNotIncludingScale);

	UE_LOG(LogTemp, Warning, TEXT("constructor"));
}






void APickup::TriggerEnter(class UPrimitiveComponent* HitComp, class AActor* OtherActor, class UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult & SweepResult)
{
	UE_LOG(LogTemp, Warning, TEXT("DESTROY"));
	Destroy();
}

Instead of:



PickUpBox->AttachToComponent(PickUpRoot, FAttachmentTransformRules::SnapToTargetNotIncludingScale);

Try:



PickupBox->SetupAttachment(RootComponent);
3

Try:
PickUpBox->bGenerateOverlapEvents = true;
PickupBox->SetCollisionProfileName(“OverlapAll”);

bGenerateOverlapEvents has to be true for the owning actor as well. And the actor has to tick. Otherwise, nothing will run.

Actors don’t have to tick to generate collision events.
