Pstomp
The pstomp command is intended to make the player stomp on enemies that have been shrunk with the Shrinker weapon. When called, it will make the player nearest the enemy look down and execute the kick animation.
The pstomp command should only be applied to the code of the actor that is being stomped. Should you place the code in the aplayer code, the player will execute the stomp action and then instantly die, having "stomped himself."
