  8. //    Notes:

  10. //    Common modifications:
  11. //
  12. //        To test a trigger at each waypoint, place a GetNextMoveWaypoint transition specification before
  13. //            including this file.
  14. //        To test a trigger at every movement step, place an Advance transition specification before
  15. //            including this file.  BEWARE:  this trigger will potentially be tested MANY times a second.

  19. //    Usage:
