Hi. Looks like there's no .cap here, but nevertheless you can think about tiles stored in array or rex_board plugin.

You can make your figures move tile by tile of totally free (as in CoC), but in any way you should provide collisions and non-passable tiles (tiles where your walls and buildings are).
