Enum bevy_tweening::TweeningDirection

pub enum TweeningDirection {
    Forward,
    Backward,
}

Direction a tweening animation is playing.

When playing a tweenable forward, the progress values 0 and 1 are respectively mapped to the start and end bounds of the lens(es) being used. Conversely, when playing backward, this mapping is reversed, such that a progress value of 0 corresponds to the state of the target at the end bound of the lens, while a progress value of 1 corresponds to the state of that target at the start bound of the lens, effectively making the animation play backward.

For all but RepeatStrategy::MirroredRepeat this is always TweeningDirection::Forward, unless manually configured with Tween::set_direction() in which case the value is constant equal to the value set. When using RepeatStrategy::MirroredRepeat, this is either forward (from start to end; ping) or backward (from end to start; pong), depending on the current iteration of the loop.

Variants

Forward

Animation playing from start to end.

Backward

Animation playing from end to start, in reverse.

Implementations

impl TweeningDirection

pub fn is_forward(&self) -> bool

Is the direction equal to TweeningDirection::Forward?

pub fn is_backward(&self) -> bool

Is the direction equal to TweeningDirection::Backward?

Trait Implementations

impl Clone for TweeningDirection

fn clone(&self) -> TweeningDirection

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TweeningDirection

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

Formats the value using the given formatter.

impl Default for TweeningDirection

fn default() -> Self

Returns the “default value” for a type.

impl Not for TweeningDirection

type Output = TweeningDirection

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl PartialEq for TweeningDirection

fn eq(&self, other: &TweeningDirection) -> 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.
