Struct rustbatch::math::circle::Circ

pub struct Circ {
    pub c: Vect,
    pub r: f32,
}

Circ is what we in geometry call circle. Circle is mainly for collision detection and supports collisions with Ray, Rect and it self. There are also projection methods available.

Fields

c: Vect

r: f32

Implementations

impl Circ

pub fn new(x: f32, y: f32, r: f32) -> Self

pub fn contains(&self, pos: Vect) -> bool

returns whether point ic in circle

pub fn prj_x(&self, x: f32) -> f32

projects x coordinate to y coordinate that belongs to circle or nan if there is no such y. mind that even if there are 2 possible solution for one x. If you need both solutions use precise_prf_x witch is slower but takes second solution to account.

pub fn prj_y(&self, y: f32) -> f32

opposite of prj_x

pub fn formula_x(&self, x: f32) -> (f32, f32)

used for other calculations

pub fn formula_y(&self, y: f32) -> (f32, f32)

used for other calculations

pub fn precise_prj(
    &self,
    arg: f32,
    formula: fn(_: &Self, _: f32) -> (f32, f32)
) -> [Option<f32>; 2]

used for other calculations

pub fn precise_prj_x(&self, x: f32) -> [Option<f32>; 2]

projects x coordinate to zero one or two solutions. This method is considerably slower then prj_x

pub fn precise_prj_y(&self, y: f32) -> [Option<f32>; 2]

opposite of precise_prj_x
