63    @brief
64        The MetaPickup is a Pickupable that can, depending on the parameter <em>metaTye</em>, do different things. If the <em>metaTye</em> is set to
65        - @b use All the @ref orxonox::Pickupable "Pickupables", the PickupCarrier has, are immediately set to used upon using the MetaPickup.
66        - @b drop All the @ref orxonox::Pickupable "Pickupables", the PickupCarrier has, are immediately dropped upon using the MetaPickup.
67        - @b destroy All the @ref orxonox::Pickupable "Pickupables", the PickupCarrier has, are immediately destroyed upon using the MetaPickup.
68        - @b destroyCarrier The PickupCarrier is immediately destroyed upon using the MetaPickup.
69
70        The default value is <em>none</em>, which basically does nothing.
71       
72        The parameter <b>activation type</b> can be used to specify, whether the MetaPickup is used upon pickup (<em>immediate</em>) or not (<em>onUse</em>). With <em>immediate</em> being the default.
73
74        An example of a XML implementation of a MetaPickup would be:
75        @code
76        <MetaPickup
77            activationType = "immediate"
78            metaType = "use"
79        />
