Struct Rect2i

#[repr(C)]
pub struct Rect2i {
    pub position: Vector2i,
    pub size: Vector2i,
}

2D axis-aligned integer bounding box.

Rect2i consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.

All bounding-box types

Dimension	Floating-point	Integer
2D	Rect2	Rect2i
3D	Aabb

You can convert to Rect2 using cast_float().

Rect2i (stable)

Fields

position: Vector2i

The position of the rectangle.

size: Vector2i

The size of the rectangle.

Implementations

impl Rect2i

pub const fn new(position: Vector2i, size: Vector2i) -> Rect2i

Create a new Rect2i from a position and a size.

Godot equivalent: Rect2i(Vector2i position, Vector2i size)

pub const fn from_components(x: i32, y: i32, width: i32, height: i32) -> Rect2i

Create a new Rect2i from four i32s representing position (x,y) and size (width,height).

Godot equivalent: Rect2i(float x, float y, float width, float height)

pub fn from_corners(position: Vector2i, end: Vector2i) -> Rect2i

Create a new Rect2i with the first corner at position and the opposite corner at end.

pub const fn from_rect2(rect: Rect2) -> Rect2i

👎Deprecated: Moved to Rect2::cast_int()

pub const fn cast_float(self) -> Rect2

Create a new Rect2 from a Rect2i, using as for i32 to real conversions.

Godot equivalent: Rect2(Rect2i from)

pub const fn end(self) -> Vector2i

The end of the Rect2i calculated as position + size.

Godot equivalent: Rect2i.size property

pub fn set_end(&mut self, end: Vector2i)

Set size based on desired end-point.

Godot equivalent: Rect2i.size property

pub fn abs(self) -> Rect2i

Returns a Rect2i with equivalent position and area, modified so that the top-left corner is the origin and width and height are positive.

pub const fn encloses(self, other: Rect2i) -> bool

Returns true if this Rect2i completely encloses another one.

Any Rect2i encloses itself, i.e. an enclosed Rect2i does is not required to be a proper sub-rect.

pub fn expand(self, to: Vector2i) -> Rect2i

Returns a copy of this Rect2i expanded so that the borders align with the given point.

pub const fn area(self) -> i32

Returns the area of the Rect2i.

Godot equivalent: Rect2i.get_area function

pub fn center(self) -> Vector2i

Returns the center of the Rect2i, which is equal to position + (size / 2).

If size is an odd number, the returned center value will be rounded towards position.

Godot equivalent: Rect2i.get_center function

pub fn grow(self, amount: i32) -> Rect2i

Returns a copy of the Rect2i grown by the specified amount on all sides.

amount may be negative, but care must be taken: If the resulting size has negative components the computation may be incorrect.

pub fn grow_individual( self, left: i32, top: i32, right: i32, bottom: i32, ) -> Rect2i

Returns a copy of the Rect2i grown by the specified amount on each side individually.

The individual amounts may be negative, but care must be taken: If the resulting size has negative components the computation may be incorrect.

pub fn grow_side(self, side: Side, amount: i32) -> Rect2i

Returns a copy of the Rect2i grown by the specified amount on the specified RectSide.

amount may be negative, but care must be taken: If the resulting size has negative components the computation may be incorrect.

pub const fn has_area(self) -> bool

Returns true if the Rect2i has area, and false if the Rect2i is linear, empty, or has a negative size.

pub const fn contains_point(self, point: Vector2i) -> bool

Returns true if the Rect2i contains a point. By convention, the right and bottom edges of the Rect2i are considered exclusive, so points on these edges are not included.

Godot equivalent: Rect2i.has_point function

pub fn intersection(self, b: Rect2i) -> Option<Rect2i>

Returns the intersection of this Rect2i and b.

If the rectangles do not intersect, None is returned.

Note that rectangles that only share a border do not intersect.

pub fn intersects(self, b: Rect2i) -> bool

Returns true if the Rect2i overlaps with b (i.e. they have at least one point in common)

pub fn merge(self, b: Rect2i) -> Rect2i

Returns a larger Rect2i that contains this Rect2i and b.

pub const fn is_negative(self) -> bool

Returns true if either of the coordinates of this Rect2is size vector is negative.

pub const fn assert_nonnegative(self)

Assert that the size of the Rect2i is not negative.

Certain functions will fail to give a correct result if the size is negative.

Trait Implementations
