AABB, or axis-aligned bounding box, is defined by a minimum point and a maximum point. It is used for broad-phase collision detection. It represents a rectangular outline of the shape so we can quickly insert shapes into a SpatialHash.
Properties
public Vector2 Min
The minimum point of the AABB.
public Vector2 Max
The maximum point of the AABB.
public float Width
The width of the AABB.
public float Height
The height of the AABB.
public float Right
The right point of the AABB.
public float Left
The left point of the AABB.
public float Top
The top point of the AABB.
public float Bottom
The bottom point of the AABB.
Methods
public static AABB FromVertices(IEnumerable vertices)
Can be used to generate an AABB from an arbitrary collection of vertices. It is generally better to define a more efficient AABB generation method based on the properties of a particular shape, but this can be used for an arbitrary collection of vertices, like a polygon.
public static AABB Transformed(AABB aabb, Transform2D transform)
Efficiently transforms an AABB. Used internally by SpatialHash to quickly transform a shape's AABB.
public static bool TestOverlap(AABB a, AABB b)
Efficiently checks if two AABBs overlap.
