grid based pathfinding help

I never knew you could use bitmasks to do something neat like this, I wish I knew that sooner.

they're pretty useful, I've been using them for pretty much everything map generating related

they work well with road/maze generators because you can do a switch statement to put the correct road tile down
and it's easy to generate the bitmasks in the first place (linking two nodes is just %westNode |= $paths[east]; %eastNode |= $paths[west];)

May I see a bigger example? Would really love to try this out.

source code is near the bottom
to run it, you're going to need to find and replace 6887 with your ID
run DCG_update(); to update the file (and do it after you spawn in)
run DCG_buildCity(); to generate and build the city
(DCG = DuckCityGenerator)
