It's been awhile since I worked with Unity--been too distracted with Legend of Grimrock. I decided to try to get something done today, breaking apart the project into bite size chunks. I figured I might as well start tackling the heart of the game first, and spent the morning getting a basic system worked out for orbiting the planets around the sun. I'm not quite satisfied with this--for one thing, I can't seem to work out a way to make the planets rotate in sync with their orbit. I'm guessing there's some heavy math involved in something like that, so I might just fudge it. No reason (I can think of) why I can't just pick some textures that won't make much difference how they're angled. In other words, making a ringed planet like Saturn look right would probably drive me nuts, so I might just stick to rocky worlds and gas giants. At any rate, I'm fairly pleased with this part. Now I just need to make some ships that will rotate around their respective planets.
