Type Definition olc_pixel_game_engine::Vf2d

type Vf2d = V2d<f32>;

Mirror of olc::vf2d. A 2D float vector type. Implements std::ops::Add, std::ops::Sub, std::ops::Mul, and std::ops::Div as well as all their assignment equivalents.

Example usage:

let mut a = Vf2d::new(10.0, 20.0) - Vf2d { x: 5.0, y: 5.0 };
a /= (5f32, 5f32).into();
assert_eq!(a, Vf2d::new(1.0, 3.0));

Implementations

impl Vf2d

pub fn mag(&self) -> f32

Returns magnitude (or length) of a vector.

pub fn mag2(&self) -> f32

Returns magnitude squared.

pub fn norm(&self) -> Self

Returns vector norm.

pub fn perp(&self) -> Self

Returns perpendicular vector.

pub fn dot(&self, rhs: Vf2d) -> f32

Returns dot product of two vectors.

pub fn cross(&self, rhs: Vf2d) -> f32

Returns cross product of two vectors.
