Alright. Pathfinding work today. This time I think I've got it nailed. I haven't quite finished it, but by tomorrow, the code should be finished, and maybe even commented in full. It's a bit of a mess, but it should work reasonably well. Not much else to say, really. This grunt work doesn't seem to result in much visible change, but it's all there. It must be painful being a programmer who doesn't get to see his work in action until everything comes together at the end of the project. I'm looking forward to making some sort of playable game.
My condolences to the friends and family of the September 11 victims.
