    @brief
        The CollectiblePickup class encompasses all @ref orxonox::Pickupable "Pickupables" that can be added to a @ref orxonox::PickupCollection "PickupCollection" and thus be part of such.

        All you need to do to make your @ref orxonox::Pickupable "Pickupable" a CollectiblePickup is to, in some way, inherit from it. (The @ref orxonox::Pickup "Pickup" class, for example, is already a CollectiblePickup).
