ok, i just tried it again. Still have no clue how to move or fire. That version is too simplistic (just fire a torpedo at X Y and you destroy the klingon) and the bsdgame original is completely arcane. this is what the man page says about movement and targeting:
"""
The course is determined by the Space Inertial Navigation
System [SINS]. As described in Star Fleet Technical Order
TO:02:06:12, the SINS is calibrated, after which it becomes the
base for navigation. If damaged, navigation becomes inaccurate.
When it is fixed, Spock recalibrates it, however, it cannot be
calibrated extremely accurately until you dock at starbase.
"""
looking at the source it validates course as 0 to 360.. so looks like angle. yet 0 goes up. 90 goes up...
