This was just an old task I wanted to finish and that was to finally learn pathfinding correctly (A* that is). Dumped my old code and read an article on A* and after 5 months it all made since... not like I learned anything new about programming, just that I finally understood it. Its all done in javascript and I used mootools to help with html generation
. Overall I am very happy I finally got around to this, I just wish I understood this before when I was working on the web client for a mmorpg.
