Change Defualt Pawn

Hi. I create a blank code project. and try to create new Character for DefaultPawn in game mode;

and attach to MyCharacter a sphere for collision;

and make a Actor. but I cant detect player overlap with this actor :

void AScorePoint::ReceiveActorBeginOverlap(class AActor* other)
{
	Super::ReceiveActorBeginOverlap(other);
	APlayerCharacter* playerCharacter = Cast<APlayerCharacter>(other);
	if (playerCharacter && playerCharacter->isAlive)
	{
		Destroy();
	}
}

and Score Point Actor Has a sphere for collision

I would make sure that your collision presets are setup correctly
