getInterpolation
public abstract float getInterpolation (float input)
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 |
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 | |
---|---|
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. |
