0 comments by johnmatthais on Oct 4th, 2012


I finally added pathfinding to my Ludum Dare game from April. Hopefully this will end a lot of problems with the game, the biggest being that people would commonly get stuck on buildings.

The pathfinding solution actually uses Game Maker's built-in paths, so I'm not sure how reliable they are just yet, but I'm giving them a shot in IPSA, and if they don't work out, I'll find a new solution for later projects.

If anyone notices any other oddities, leave a comment, and I'll fix it right up. :)

Afro Samurai needs a PC port so I can play it in 1080p.

@Worthless_Bums Ah, yeah, that would do it. I learned long ago never to code tired. I have to clean up too much the next day.

@Worthless_Bums Aren't those usually the solutions that end up working, though? ;)

@Worthless_Bums Maybe sticking a puppy picture in the code will work.
