Current questions and answers regarding the map editor.

What if we take a section of the map, say, 100x100, run a loop of 10,000 iterations, checking each tile using IsTilePassable(nX, nY, nFloorID = GROUND), and if the tile is passable, add it to an array? Then, for teleporting a creature, use an element from that array? I don't really know yet how to do this exactly, and whether it would significantly impact the gameplay.
