/proc/generate_adjacent_directions	Encodes connectivity between border objects Returns a list accessable by a border object's dir, the direction between it and a target, and a target Said list will return the direction the two objects connect, if any exists (if the target isn't a border object and the direction is fine, return the inverse of the direction in use)
CAN_DIAGONAL_SMOOTH	Are two atoms border adjacent, takes a border object, something to compare against, and the direction between A and B Returns the way in which the first thing is adjacent to the second
BITMASK_FOUND	Check that non border objects use to smooth against border objects
BITMASK_ON_BORDER_CHECK	Returns true if the smooth is acceptable, FALSE otherwise
/proc/dir_to_all_junctions	Takes a direction, turns it into all the junctions that contain it

Define Details

#define
BITMASK_FOUND
(target, direction, direction_flag)

Check that non border objects use to smooth against border objects

#define
BITMASK_ON_BORDER_CHECK
(target, direction)

Returns true if the smooth is acceptable, FALSE otherwise

#define
CAN_DIAGONAL_SMOOTH
(border_obj, target, direction)

Are two atoms border adjacent, takes a border object, something to compare against, and the direction between A and B Returns the way in which the first thing is adjacent to the second
