class DecelerateInterpolator : Interpolator

| Parameters | |
|---|---|
factor: Float |
Degree to which the animation should be eased. Setting factor to 1.0f produces an upside-down y=x^2 parabola. Increasing factor above 1.0f makes exaggerates the ease-out effect (i.e., it starts even faster and ends evens slower) |
Public functions
getInterpolation
fun getInterpolation(input: @FloatRange(from = 0, to = 1) Float): @FloatRange(from = 0, to = 1) Float
Maps a value representing the elapsed fraction of an animation to a value that represents the interpolated fraction. This interpolated value is then multiplied by the change in value of an animation to derive the animated value at the current elapsed animation time.
| Parameters | |
|---|---|
input: @FloatRange(from = 0, to = 1) Float |
A value between 0 and 1.0 indicating our current point in the animation where 0 represents the start and 1.0 represents the end |
| Returns | |
|---|---|
@FloatRange(from = 0, to = 1) Float |
The interpolation value. This value can be more than 1.0 for interpolators which overshoot their targets, or less than 0 for interpolators that undershoot their targets. |
