y: f32

Y coordinate

Methods

impl Vec2

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

Create a new Vec2

pub fn zero() -> Self

Create a zero Vec2

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

Calculate the dot product of two Vec2s

pub fn mag(self) -> f32

Get the magnitude of a Vec2

pub fn normalize(self) -> Self

Normalize a Vec2

pub fn dist_sq(self, other: Self) -> f32

Calculate the distance squared between two Vec2

pub fn dist(self, other: Self) -> f32

Calculate the distance between two Vec2

pub fn midpoint(self, other: Self) -> Self

Find the midpoint between two Vec2

pub fn left(self) -> Self

Create a left-hand perpendicular Vec2

pub fn right(self) -> Self

Create a right-hand perpendicular Vec2

pub fn widdershins(self, other: Self) -> bool

Calculate winding order for two Vec2.

The Vec2 should be initialized as edges pointing toward the same vertex. Returns true if the winding order is widdershins (counter-clockwise).

pub fn lerp(self, other: Self, t: f32) -> Self

Calculate linear interpolation of two Vec2

pub fn angle(&self, other: Vec2) -> f32

Calculate angle between 2 Vec2's (on a plane they both lie on)
