/datum/shape

A simple geometric shape for testing collisions and intersections. This one is a single point.

Vars
bounds_x	Distance from the shape's leftmost to rightmost extent.
bounds_y	Distance from the shape's topmost to bottommost extent.
center_x	Horizontal position of the shape's center point.
center_y	Vertical position of the shape's center point.
Procs
contains_atom	Returns TRUE if the atom is in or on the shape, otherwise FALSE.
contains_coords	Returns TRUE if the coord datum is in or on the shape, otherwise FALSE.
contains_xy	Returns TRUE if the coordinates x, y are in or on the shape, otherwise FALSE.
intersects_aabb	Returns TRUE if this shape's bounding box intersects the provided shape's bounding box, otherwise FALSE. Generally faster than a full intersection test.
intersects_rect	Returns TRUE if this shape intersects the provided rectangle shape, otherwise FALSE.
set_shape	Assign shape variables.

Var Details

var

Proc Details

proc
contains_atom
(/atom/atom)

Returns TRUE if the atom is in or on the shape, otherwise FALSE.

proc
contains_coords
(/datum/coords/coords)

Returns TRUE if the coord datum is in or on the shape, otherwise FALSE.

proc
contains_xy
(x, y)

Returns TRUE if the coordinates x, y are in or on the shape, otherwise FALSE.

proc
intersects_aabb
(/datum/shape/aabb)

Returns TRUE if this shape's bounding box intersects the provided shape's bounding box, otherwise FALSE. Generally faster than a full intersection test.

proc
intersects_rect
(/datum/shape/rectangle/rect)

Returns TRUE if this shape intersects the provided rectangle shape, otherwise FALSE.

proc
set_shape
(center_x, center_y)

Assign shape variables.
