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.

Property Descriptions

Vector2 end = Vector2(0, 0)

The ending point. This is usually the bottom-right corner of the rectangle, and is equivalent to position + size. Setting this point affects the size.

Vector2 position = Vector2(0, 0)

The origin point. This is usually the top-left corner of the rectangle.

Vector2 size = Vector2(0, 0)

The rectangle's width and height, starting from position. Setting this value also affects the end point.

Note: It's recommended setting the width and height to non-negative values, as most methods in Godot assume that the position is the top-left corner, and the end is the bottom-right corner. To get an equivalent rectangle with non-negative size, use abs.

Constructor Descriptions

Rect2 Rect2 ( )

Constructs a Rect2 with its position and size set to Vector2.ZERO.

Rect2 Rect2 ( Rect2 from )

Constructs a Rect2 as a copy of the given Rect2.

Rect2 Rect2 ( Rect2i from )

Constructs a Rect2 from a Rect2i.

Rect2 Rect2 ( Vector2 position, Vector2 size )

Constructs a Rect2 by position and size.

Rect2 Rect2 ( float x, float y, float width, float height )

Constructs a Rect2 by setting its position to (x, y), and its size to (width, height).

Method Descriptions

Rect2 abs ( ) const

Returns a Rect2 equivalent to this rectangle, with its width and height modified to be non-negative values, and with its position being the top-left corner of the rectangle.

var rect = Rect2(25, 25, -100, -50)
var absolute = rect.abs() # absolute is Rect2(-75, -25, 100, 50)
