Struct Vec2 

#[repr(C)]
pub struct Vec2 {
    pub x: f32,
    pub y: f32,
}

A 2-dimensional vector with f32 components.

Fields

x: f32

The x component of the vector.

y: f32

The y component of the vector.

Implementations

impl Vec2

pub const ZERO: Self

A vector with all components set to 0.0.

pub const ONE: Self

A vector with all components set to 1.0.

pub const X: Self

The unit vector pointing along the positive X-axis.

pub const Y: Self

The unit vector pointing along the positive Y-axis.

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

Creates a new Vec2 with the specified components.

pub const fn abs(self) -> Self

Returns a new vector with the absolute value of each component.

pub fn length_squared(&self) -> f32

Calculates the squared length (magnitude) of the vector. This is faster than length() as it avoids a square root.

pub fn length(&self) -> f32

Calculates the length (magnitude) of the vector.

pub fn normalize(&self) -> Self

Returns a normalized version of the vector with a length of 1. If the vector’s length is near zero, it returns Vec2::ZERO.

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

Calculates the dot product of this vector and another.

pub fn lerp(start: Self, end: Self, t: f32) -> Self

Performs a linear interpolation between two vectors. The interpolation factor t is clamped to the [0.0, 1.0] range.
