Rect2 provides an 2D Axis-Aligned Bounding Box. It consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.

Member Function Description

Construct a Rect2 by position and size.

Construct a Rect2 by x, y, width and height.

Returns the intersection of this Rect2 and b.

Returns true if this Rect2 completely encloses another one.

Return this Rect2 expanded to include a given point.

Get the area of the Rect2.

Return a copy of the Rect2 grown a given amount of units towards all the sides.

  • bool has_no_area ( )

Return true if the Rect2 is flat or empty.

Return true if the Rect2 contains a point.

Return true if the Rect2 overlaps with another.

Combine this Rect2 with another, a larger one is returned that contains both.
