Struct bevy_math::primitives::Direction2d

pub struct Direction2d(/* private fields */);

A normalized vector pointing in a direction in 2D space

Implementations

impl Direction2d

pub const X: Self = _

A unit vector pointing along the positive X axis.

pub const Y: Self = _

A unit vector pointing along the positive Y axis.

pub const NEG_X: Self = _

A unit vector pointing along the negative X axis.

pub const NEG_Y: Self = _

A unit vector pointing along the negative Y axis.

pub fn new(value: Vec2) -> Result<Self, InvalidDirectionError>

Create a direction from a finite, nonzero Vec2.

Returns Err(InvalidDirectionError) if the length of the given vector is zero (or very close to zero), infinite, or NaN.

pub fn new_unchecked(value: Vec2) -> Self

Create a Direction2d from a Vec2 that is already normalized.

Warning

value must be normalized, i.e it’s length must be 1.0.

pub fn new_and_length(value: Vec2) -> Result<(Self, f32), InvalidDirectionError>

Create a direction from a finite, nonzero Vec2, also returning its original length.

Returns Err(InvalidDirectionError) if the length of the given vector is zero (or very close to zero), infinite, or NaN.

pub fn from_xy(x: f32, y: f32) -> Result<Self, InvalidDirectionError>

Create a direction from its x and y components.

Returns Err(InvalidDirectionError) if the length of the vector formed by the components is zero (or very close to zero), infinite, or NaN.

Trait Implementations

impl Clone for Direction2d

fn clone(&self) -> Direction2d

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Direction2d

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

Formats the value using the given formatter.

impl Deref for Direction2d

type Target = Vec2

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Neg for Direction2d

type Output = Direction2d

The resulting type after applying the - operator.

fn neg(self) -> Self::Output

Performs the unary - operation.

impl PartialEq for Direction2d

fn eq(&self, other: &Direction2d) -> 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 TryFrom<Vec2> for Direction2d

type Error = InvalidDirectionError

The type returned in the event of a conversion error.

fn try_from(value: Vec2) -> Result<Self, Self::Error>

Performs the conversion.
