pub struct Circle {
    pub radius: f32,
}
Expand description

A circle primitive

Fields§

§radius: f32

The radius of the circle

Implementations§

source§

impl Circle

source

pub const fn new(radius: f32) -> Self

Create a new Circle from a radius

source

pub fn diameter(&self) -> f32

Get the diameter of the circle

source

pub fn area(&self) -> f32

Get the area of the circle

source

pub fn perimeter(&self) -> f32

Get the perimeter or circumference of the circle

source

pub fn closest_point(&self, point: Vec2) -> Vec2

Finds the point on the circle that is closest to the given point.

If the point is outside the circle, the returned point will be on the perimeter of the circle. Otherwise, it will be inside the circle and returned as is.

Trait Implementations§

impl Bounded2d for Circle

source§

fn aabb_2d(&self, translation: Vec2, _rotation: f32) -> Aabb2d

Get an axis-aligned bounding box for the shape with the given translation and rotation. The rotation is in radians, counterclockwise, with 0 meaning no rotation.

fn bounding_circle(&self, translation: Vec2, _rotation: f32) -> BoundingCircle

Get a bounding circle for the shape The rotation is in radians, counterclockwise, with 0 meaning no rotation.

impl PartialEq for Circle

source§

fn eq(&self, other: &Circle) -> bool
