Implementations

impl Vec2Fix

pub const ZERO: Self

Zero vector (0, 0)

pub const ONE: Self

One vector (1, 1)

pub const UNIT_X: Self

Unit X vector (1, 0)

pub const UNIT_Y: Self

Unit Y vector (0, 1)

pub const fn new(x: Fix128, y: Fix128) -> Self

Create a new 2D vector.

pub const fn from_int(x: i64, y: i64) -> Self

Create from integer components.

pub fn length_squared(self) -> Fix128

Squared length (avoids sqrt).

pub fn length(self) -> Fix128

Length (magnitude).

pub fn normalize(self) -> Self

Normalize to unit length. Returns ZERO for zero-length vectors.

pub fn dot(self, rhs: Self) -> Fix128

Dot product.

pub fn cross_scalar(self, rhs: Self) -> Fix128

2D cross product (returns a scalar: a.x * b.y - a.y * b.x).

This is the z-component of the 3D cross product when both vectors are embedded in the XY plane.

pub fn rotate(self, angle: Fix128) -> Self

Rotate this vector by an angle (radians, counter-clockwise).

pub fn perpendicular(self) -> Self

Return the perpendicular vector (90 degrees counter-clockwise): (-y, x).

pub fn distance_to(self, other: Self) -> Fix128

Distance to another point.

pub fn lerp(self, other: Self, t: Fix128) -> Self

Linear interpolation: self + (other - self) * t.

pub fn scale(self, s: Fix128) -> Self

Scale by a scalar.
