Brag, naw... it's just an easy algo. Esp. if you have a handy book right in front of you with the psudeo code. :lol:

For this little tile-based game, it only took me a few hours to add. Maybe an hour or two to fix any mistakes that I made myself and it was done and worked quite well.

Continious enviroments would take a bit mor coding to get a node system down, but other than that a basic one shouldn't take a really long time, I don't think.

How does your implimentation determine which node the enemy/player was on/at?
