velocity, and now it's known as such. The actor variables momx/momy/momz are now known as velx/vely/velz, and the ACS functions GetActorMomX/Y/Z are now known as GetActorVelX/Y/Z. For compatibility, momx/momy/momz will continue to work as aliases from DECORATE. The ACS functions, however, require you to use the new name, since they never saw an official release yet.
