Trait ark_api::CoordinateSystem

pub trait CoordinateSystem {
    fn up() -> Self;
    fn down() -> Self;
    fn right() -> Self;
    fn left() -> Self;
    fn forward() -> Self;
    fn back() -> Self;
}

Coordinate system extension to Vec3

This crate is opinionated with what coordinate system it uses and this adds additional functions to acccess the coordinate system axis

The exact coordinate system we use is right-handed with +X = right, +Y = up, -Z = forward, +Z = back

Required Methods

fn up() -> Self

A unit length vector pointing in the canonical up direction.

fn down() -> Self

A unit length vector pointing in the canonical down direction.

fn right() -> Self

A unit length vector pointing in the canonical right direction.

This is the right hand side of a first person character.

fn left() -> Self

A unit length vector pointing in the canonical left direction.

fn forward() -> Self

A unit length vector pointing in the canonical forward direction.

This is the direction a character faces, or a car drives towards.

fn back() -> Self

A unit length vector pointing in the canonical back direction.
