@sqiddster The idea was to have a space ship that could move around freely. The player ship's turrets would shoot the enemy weapons if it got within a certain range. I was thinking of basing it on vector rather than speed, as the turrets didn't have movement (so to speak) even though they do move.
I've tried it with @Ashley / @Yanns code, but they all seemed to aim *dumb*.
If the ships were just moving I could base the speed, etc off of the ship... but as you said, it's the rotation that seems to mess things up.
This one got us beat?
