Package icyllis.modernui.animation

Class AnticipateOvershootInterpolator

java.lang.Object

icyllis.modernui.animation.AnticipateOvershootInterpolator

All Implemented Interfaces:

TimeInterpolator

public class AnticipateOvershootInterpolator
extends Object
implements TimeInterpolator

An interpolator where the change starts backward then flings forward and overshoots the target value and finally goes back to the final value.

Constructor Details

AnticipateOvershootInterpolator

public AnticipateOvershootInterpolator()

See Also:

• TimeInterpolator.ANTICIPATE_OVERSHOOT

AnticipateOvershootInterpolator

public AnticipateOvershootInterpolator(float tension)

Parameters:

tension - Amount of anticipation/overshoot. When tension equals 0.0f, there is no anticipation/overshoot and the interpolator becomes a simple acceleration/deceleration interpolator.

AnticipateOvershootInterpolator

public AnticipateOvershootInterpolator(float tension,
 float extraTension)

Parameters:

tension - Amount of anticipation/overshoot. When tension equals 0.0f, there is no anticipation/overshoot and the interpolator becomes a simple acceleration/deceleration interpolator.

extraTension - Amount by which to multiply the tension. For instance, to get the same overshoot as an OvershootInterpolator with a tension of 2.0f, you would use an extraTension of 1.5f.

Method Details

getInterpolation

public float getInterpolation(float t)

Description copied from interface: TimeInterpolator

Get interpolation value. 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.

Specified by:

getInterpolation in interface TimeInterpolator

Parameters:

t - [0.0, 1.0] determined by timeline, 0.0 represents the start and 1.0 represents the end

Returns:

the interpolated value. this value can be more than 1.0 for those overshoot their targets, or less than 0 for those undershoot their targets.
