you ask how is that? well it a veiw point of distance of object like treasure chest by 3 space ahead of player really their is 4 spaces ahead tho. so if you look at @MAP1 you will see different numbers in the data of map1 right those are points of reference on the map like a wall or ladder,ect. nmap read distance of let say 2 which is a ladder, if player is 3 spaces away from the number 2=ladder
