Struct KeyframeAnimator 

pub struct KeyframeAnimator {
    pub keyframes: Vec<DeformKeyframe>,
    pub interpolation: KeyframeInterp,
    pub looping: bool,
    pub time: f32,
}

Animates a scalar value over time using keyframes.

Fields

keyframes: Vec<DeformKeyframe>

interpolation: KeyframeInterp

looping: bool

Whether the animation loops.

time: f32

Current time.

Implementations

impl KeyframeAnimator

pub fn new() -> Self

Create a new keyframe animator.

pub fn add_key(&mut self, time: f32, value: f32)

Add a keyframe.

pub fn with_interpolation(self, interp: KeyframeInterp) -> Self

Set interpolation mode.

pub fn with_looping(self, looping: bool) -> Self

Enable looping.

pub fn tick(&mut self, dt: f32)

Advance time by dt.

pub fn evaluate(&self) -> f32

Evaluate the animated value at the current time.

pub fn evaluate_at(&self, time: f32) -> f32

Evaluate the animated value at a specific time.

pub fn duration(&self) -> f32

Get the total duration of the animation.

pub fn is_finished(&self) -> bool

Check if the animation is finished (time past last keyframe).

pub fn reset(&mut self)

Reset animation time to the start.

Trait Implementations

impl Default for KeyframeAnimator

fn default() -> Self

Returns the “default value” for a type.
