Struct ggez::graphics::Rect

pub struct Rect {
    pub x: f32,
    pub y: f32,
    pub w: f32,
    pub h: f32,
}

A simple 2D rectangle.

The origin of the rectangle is at the top-left, with x increasing to the right and y increasing down.

Fields

x: f32

X coordinate of the left edge of the rect.

y: f32

Y coordinate of the top edge of the rect.

w: f32

Total width of the rect

h: f32

Total height of the rect.

Implementations

impl Rect

pub const fn new(x: f32, y: f32, w: f32, h: f32) -> Self

Create a new Rect.

pub fn fraction(x: f32, y: f32, w: f32, h: f32, reference: &Rect) -> Rect

Creates a new Rect a la Love2D’s love.graphics.newQuad, as a fraction of the reference rect’s size.

pub fn new_i32(x: i32, y: i32, w: i32, h: i32) -> Self

Create a new rect from i32 coordinates. Loses precision if the integers are too big to fit in f32’s.

pub const fn zero() -> Self

Create a new Rect with all values zero.

pub const fn one() -> Self

Creates a new Rect at 0,0 with width and height 1.

pub const fn point(&self) -> Point2<f32>

Gets the Rect’s x and y coordinates as a Point2.

pub fn center(&self) -> Point2<f32>

Gets the Rect’s center x and y coordinates as a Point2.

pub const fn left(&self) -> f32

Returns the left edge of the Rect

pub fn right(&self) -> f32

Returns the right edge of the Rect

pub const fn top(&self) -> f32

Returns the top edge of the Rect

pub fn bottom(&self) -> f32

Returns the bottom edge of the Rect

pub fn contains<P>(&self, point: P) -> bool where
    P: Into<Point2<f32>>, 

Checks whether the Rect contains a Point

pub fn overlaps(&self, other: &Rect) -> bool

Checks whether the Rect overlaps another Rect

pub fn translate<V>(&mut self, offset: V) where
    V: Into<Vector2<f32>>, 

Translates the Rect by an offset of (x, y)

pub fn move_to<P>(&mut self, destination: P) where
    P: Into<Point2<f32>>, 

Moves the Rect’s origin to (x, y)

pub fn scale(&mut self, sx: f32, sy: f32)

Scales the Rect by a factor of (sx, sy), growing towards the bottom-left

pub fn rotate(&mut self, rotation: f32)

Calculated the new Rect around the rotated one.

pub fn combine_with(self, other: Rect) -> Rect

Returns a new Rect that includes all points of these two Rects.

Trait Implementations
