org.vanted.animation.loopers.ForwardLooper

public class ForwardLooper
extends Looper

Similar to a StandardLooper but allows interpolators to interpolate from the end of the animation to the start of the animation.
Note: This looper should only be used with that are continuous. Use a StandardLooper for animations that do not have a continuous element. (continuous animations usually inherit from ContinousAnimation.
Note: A ForwardLooper should only be used if the animation's loopDuration is longer than the largest time value in the animation's set of data points.

Description copied from class: Looper

Calculates how far the time is from the next data point as a percentage.
Eg. If there are 4 points with times: 3,6,7,9 and time = 6.5 then this method will return 0.5 because 6.5-6/7-6 = 0.5

Overrides:

getNormalizedTime in class Looper

Type Parameters:

V - The type of data value that the data point holds.

T - The type of data point that the interpolator is interpolating for.

Parameters:

time - The time has elapsed since the start of the animation.

loopDuration - How long each loop takes in milliseconds

dataPoints - All the dataPoints that the interpolator needs to interpolate between

pointsUsed - The points being used for the interpolation.

Returns:

A value between 0 and 1.
