Rect2¶
A 2D axis-aligned bounding box using floating-point coordinates.
Description¶
The Rect2 built-in Variant type represents an axis-aligned rectangle in a 2D space. It is defined by its position and size, which are Vector2. It is frequently used for fast overlap tests (see intersects). Although Rect2 itself is axis-aligned, it can be combined with Transform2D to represent a rotated or skewed rectangle.
For integer coordinates, use Rect2i. The 3D equivalent to Rect2 is AABB.
Note: Negative values for size are not supported. With negative size, most Rect2 methods do not work correctly. Use abs to get an equivalent Rect2 with a non-negative size.
Note: In a boolean context, a Rect2 evaluates to false if both position and size are zero (equal to Vector2.ZERO). Otherwise, it always evaluates to true.
