Struct yoyo_physics::decay::Decay

pub struct Decay<T> where
    T: Float,  {
    pub from_value: T,
    pub to_value: T,
    pub time_constant: f32,
}

Decay curve that starts at a given value and decelerates to a given target value.

Fields

from_value: T

Start value of the animation.

to_value: T

Target value of the animation.

time_constant: f32

Adjusting the time constant will change the duration of the deceleration, thereby affecting its feel.

Implementations

impl<T> Decay<T> where
    T: Float, 

pub fn ideal_target(from_value: T, power: T, velocity: T) -> T

Computes the ideal target of the decay.

Trait Implementations

type Value = T

This is the type that this curve operates on.

type Velocity = T

This is the type of velocity that this curve works with.

pub fn approximate(&self, time: f32) -> Approximation<T>

This should return a single approximation for the given time.

pub fn target(&self) -> T
