@lordhershey, each room is divided into a 5x5 grid of sections. There are a possible 40 different locations for inner wall pieces (20 possible horizontally and 20 possible vertically). Also, even a 5 bytes per room, if you could encrypt 4 bytes into one character in a string, then you will still use more than 1 character of a string per room. There are 1536 rooms, and only 250 String characters to work with. I would have to say that you are way off base as to how I did it, however.

1536 rooms, 4 possible entrances and 16 partitions in each room, visited status and location of player all restored. Virtual cake to anyone who can say how I did it.

I know what you mean. I had put several on the back burner -- I think the elements might need replaced they have been on there so long. It is, however, hard to get back into a project after you left it for so long.

Alright, have working code (I believe). Had to re-work the car movement and the intersection pads. Will have documented revision up soon.

I now have an occasional fender-bender at intersections that I need to fix. Just one more check to add. Will work on it in the near future.
