Hi Steve,
Yes, I remember that project start (don't remember the name) but arrowing around opened up tunnels and rooms. Your link is only downloading a screen shot.
Sorry. Copied the wrong link apparently. Try this one:
https://www.qb64.org/forum/index.php?topic=1696.msg109537#msg109537CreateMap is the sub which draws our rooms and then meanders our paths for us. My concept is really simple: Start at point A, and move towards point B, with a chance for the random variance which generates the “meandering”.
For example, say B is 10 steps due East from A...
Start at A:
East
East
North (random change)
North (again, the random change kicked in)
East
East
South (automatic course correction as we move towards B)
West (random kicked in again.)
And so on...
As long as your random variance is less than the chance for direct approach, you’ll eventually reach the goal.
