Struct Vec2 

pub struct Vec2 {
    pub x: f32,
    pub y: f32,
}

A point or a direction in a plane.

Fields

x: f32

y: f32

Implementations

impl Vec2

pub const ZERO: Vec2

pub const fn new(x: f32, y: f32) -> Vec2

pub fn dot(self, o: Vec2) -> f32

pub fn length(self) -> f32

pub fn distance(self, o: Vec2) -> f32

pub fn normalize(self) -> Vec2

This one scaled to length 1 (zero stays zero).

pub fn lerp(self, to: Vec2, t: f32) -> Vec2

pub fn perp(self) -> Vec2

Turned a quarter left (y up) — a line’s normal.
