Struct godot::builtin::Rect2

#[repr(C)]
pub struct Rect2 { pub position: Vector2, pub size: Vector2, }
Expand description

2D axis-aligned bounding box.

Rect2 consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.

Currently most methods are only available through InnerRect2.

The 3D counterpart to Rect2 is Aabb.

Implementations§

§

impl Rect2

pub const fn new(position: Vector2, size: Vector2) -> Rect2

Create a new Rect2 from a position and a size.

Godot equivalent: Rect2(Vector2 position, Vector2 size)

pub fn from_corners(position: Vector2, end: Vector2) -> Rect2

Create a new Rect2 with the first corner at position and the opposite corner at end.

pub const fn from_components(x: f32, y: f32, width: f32, height: f32) -> Rect2

Create a new Rect2 from four reals representing position (x,y) and size (width,height).

Godot equivalent: Rect2(float x, float y, float width, float height)

pub const fn from_rect2i(rect: Rect2i) -> Rect2

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

Godot equivalent: Rect2(Rect2i from)

pub fn abs(self) -> Rect2

Returns a rectangle with the same geometry, with top-left corner as position and non-negative size.

pub fn encloses(self, b: Rect2) -> bool

Whether self covers at least the entire area of b (and possibly more).

pub fn expand(self, to: Vector2) -> Rect2

Returns a copy of this rectangle expanded to include a given point.

Note: This method is not reliable for Rect2 with a negative size. Use abs to get a positive sized equivalent rectangle for expanding.

pub fn merge(self, b: Rect2) -> Rect2

Returns a larger rectangle that contains this Rect2 and b.

Note: This method is not reliable for Rect2 with a negative size. Use abs to get a positive sized equivalent rectangle for merging.

pub fn area(self) -> f32

Returns the area of the rectangle.

pub fn center(self) -> Vector2

Returns the center of the Rect2, which is equal to position + (size / 2).

pub fn grow(self, amount: f32) -> Rect2

Returns a copy of the Rect2 grown by the specified amount on all sides.

pub fn grow_individual( self, left: f32, top: f32, right: f32, bottom: f32, ) -> Rect2

Returns a copy of the Rect2 grown by the specified amount on each side individually.

pub fn grow_side(self, side: Side, amount: f32) -> Rect2

Returns a copy of the Rect2 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 fn has_area(self) -> bool

Returns true if the Rect2 has area, and false if the Rect2 is linear, empty, or has a negative size. See also get_area.

pub fn has_point(self, point: Vector2) -> bool

Returns true if the Rect2 contains a point. By convention, the right and bottom edges of the Rect2 are considered exclusive, so points on these edges are not included.

Note: This method is not reliable for Rect2 with a negative size. Use abs to get a positive sized equivalent rectangle to check for contained points.

pub fn intersection(self, b: Rect2) -> Option<Rect2>

Returns the intersection of this Rect2 and b. If the rectangles do not intersect, an empty Rect2 is returned.

pub fn intersects(self, b: Rect2) -> bool

Checks whether two rectangles have at least one point in common.

Also returns true if the rects only touch each other (share a point/edge). See intersects_exclude_borders if you want to return false in that case.

Godot equivalent: Rect2.intersects(Rect2 b, bool include_borders = true)

pub fn intersects_exclude_borders(self, b: Rect2) -> bool

Checks whether two rectangles have at least one inner point in common (not on the borders).

Returns false if the rects only touch each other (share a point/edge). See intersects if you want to return true in that case.

Godot equivalent: Rect2.intersects(AABB b, bool include_borders = false)

pub fn is_finite(self) -> bool

Returns true if this Rect2 is finite, by calling @GlobalScope.is_finite on each component.

pub fn end(self) -> Vector2

The end of the Rect2 calculated as position + size.

pub fn set_end(&mut self, end: Vector2)

Set size based on desired end-point.

pub fn assert_nonnegative(self)

Assert that the size of the Rect2 is not negative.

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