Progress on scanners, engines, and weapons

A progress report. Besides bugs and the usual other things, scanner sectors and complex engine functions are now working properly. We can now fire at a moving target with lead, accounting for both our own speed and the target's. Projectile behavior now depends on quality, so muzzle velocity varies. The barrel has dispersion, too; you can see it in the rather uneven trail of shots. For a break, and to get a better sense of scale, I temporarily put a model from Star Trek into the scene. Our little ship is docked right next to it.
