Crate simple_easing2
source ·Expand description
This package contains a set of simple easing functions. That consume a standardised time
attribute in the range between 0.0
and 1.0
, that represent the progress of a transition.
0.0
being the beginning, 1.0
the end.
They return a value between 0.0
and 1.0
(it might exceed the 0..=1
range temporarily
for a bounce effect). The returned value can be used to interpolate between the initial
(0.0
) and the final (1.0
) transition state, allowing for a “more natural” feel of
a transition by accelerating and decelerating at certain points, depending on the easing
function used.
Visit easings.net to see visualisations of the different easing functions.
All easing functions have the same signature ((f32) -> f32
) and can be easily stored as
fn pointers.
use simple_easing::linear;
let easing: fn(f32) -> f32 = linear;
assert_eq!(easing(1.0), 1.0);
Functions
- A linear easing that goes from
1.0
to0.0
. - A linear easing that goes from
0.0
to1.0
and back to0.0
. That might be used in combination with other easing functions.
