This took a very long time to figure out, since I didn't know much about vector math at first. Now I have a basic, basic understanding as pertains to game dev at least. Previously, if you tried to dock a craft at a port on the other side of the station, it would just phase right through the station. Now it'll find a path around, hooray. This is accomplished through using A* navigation and a bezier spline. I made a ton of mistakes on the way here, but I'm really happy with it now.
Next, I'm working on behavior for the 'nauts. I'm going to keep a "duty roster" on the station and 'nauts will randomly pick tasks to work on throughout their day. Sounds simple enough but we'll see.
