Added miniguns. Really quite satisfying to see spin up and fire, and setPitch() came in really handy for the background whine that needs to adjust pitch for spin speed.
I am slightly concerned about performance though since they're about 900 triangles (and about 480 verts) each. Do you think I should decrease that a bit, or will it be fine? I really haven't seen any performance impact but I'm on a GTX 760.
The billboards now have a scrolling screen-like effect that I've seen all other space games have, and it looks uncomparably more lifelike. All done using shaders of course, but nothing fancy, just a scrolling image that starts at a random point that's passed to the material when created.
All of this is hard to show in images so I'll make a short video in the weekend.
P.S. I know the station texture looks weird, I don't have any proper ones done yet so it's just one painted all over it.
