50    @brief
51        The ShrinkPickup is a Pickupable that causes the pawn to shrink to a certain size for a certain time with a certain speed, all of them specified in the following variables:
52        - The @b shrinkFactor It determines how much the ship is going to shrink (e.g. the factor 2 would make the ship shrinking to half its size).
53        - The @b duration Specifies how long the ship will stay small.
54        - The @b shrinkDuration Defines how fast the ship shrinks and grows in seconds.
55
56        An example of a XML implementation of a ShrinkPickup would be:
57        @code
58        <ShrinkPickup
59            shrinkFactor = "5.0"
60            duration = "5.0"
61            shrinkSpeed = "5.0"
