Struct pixel_game_lib::math::Rotation

pub struct Rotation { /* private fields */ }

Rotation split into it’s sine and cosine parts.

This allows something to rotate infinitely.

Implementations

impl Rotation

pub const fn zero() -> Self

With no rotation, points to the right.

pub fn from_radians(rotation: f64) -> Self

Create from radians.

pub fn from_degrees(rotation: f64) -> Self

Create from degrees.

pub fn from_direction(dir: Vec2<f64>) -> Self

Create from a direction vector.

Vector is assumed to be normalized.

pub fn to_radians(self) -> f64

Convert to radians.

pub fn to_degrees(self) -> f64

Convert to degrees.

pub fn rotate(&self, point: Vec2<f64>) -> Vec2<f64>

Rotate a point.

pub fn sin(&self) -> f64

Sine.

pub fn cos(&self) -> f64

Cosine.

Trait Implementations

impl Add<f64> for Rotation

type Output = Rotation

The resulting type after applying the + operator.

fn add(self, rhs: f64) -> Self::Output

Performs the + operation.

impl Add for Rotation

type Output = Rotation

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl AddAssign<f64> for Rotation

fn add_assign(&mut self, rhs: f64)

Performs the += operation.

impl AddAssign for Rotation

fn add_assign(&mut self, rhs: Self)

Performs the += operation.

impl Clone for Rotation

fn clone(&self) -> Rotation

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Rotation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Rotation

fn default() -> Self

Returns the “default value” for a type.

impl From<f64> for Rotation

fn from(value: f64) -> Self

Converts to this type from the input type.

impl Neg for Rotation

type Output = Rotation

The resulting type after applying the - operator.

fn neg(self) -> Self::Output

Performs the unary - operation.

impl PartialEq for Rotation

fn eq(&self, other: &Rotation) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Sub<f64> for Rotation

type Output = Rotation

The resulting type after applying the - operator.

fn sub(self, rhs: f64) -> Self::Output

Performs the - operation.

impl Sub for Rotation

type Output = Rotation

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.

impl SubAssign<f64> for Rotation

fn sub_assign(&mut self, rhs: f64)

Performs the -= operation.

impl SubAssign for Rotation

fn sub_assign(&mut self, rhs: Self)

Performs the -= operation.

impl Copy for Rotation

impl StructuralPartialEq for Rotation
