- Enough with this "momentum" garbage. What Doom calls "momentum" is really

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.
