        2) 'drop', all the pickups, the PickupCarrier has, are immediately dropped upon pickup of the MetaPickup.
        3) 'destroy', all the pickups, the PickupCarrier has, are immediately destroyed upon pickup of the MetaPickup.
        4) 'destroyCarrier', the PickupCarrier is immediately destroyed upon pickup of the MetaPickup.
