Okay, good news, bad news.
The good news is, what you see above is A* at work.
The bad news is, calculating one path every frame makes things kind of sluggish.
The good news is, I won't realistically need to do that.
The bad news is, it's still a bit too slow for comfort.
The good news is, I might be able to get it to speed up a bit tomorrow.
The bad news is.. Hmm, nope, that's it.
