Usage

ValueAnimator makes the transition from initial value to target.

Simple Linear Animation

import JJValueAnimator

let anim = JJValueAnimator.ofFloat(0, to: 100).addUpdateListener({
            [weak self ] (value) in
                // do something with value
            })
        .setDuration(400) // millis
       
anim.start()

Interpolator

The time interpolator used in calculating the elapsed fraction of the animation. The default value is Linear.

Intepolators start with JJInterpolator.

import JJValueAnimator

let  anim = JJValueAnimator...
anim.setInterpolator(JJInterpolator(ease: .ANTICIPATEOVERSHOOT))

// or

anim.setInterpolator(JJInterpolatorCycle(cycles: 4))

Custom Interpolator

You need to implement the JJTimeInterpolator protocol

class MyInterpolator : JJTimeInterpolator{


    override func getInterpolation(input: Float) -> Float {
        //do the magic
    }

}

anim.setInterpolator(MyInterpolator())

Listeners

There are JJAnimatorListener y JJAnimatorPauseListener

 anim.addListener(OnAnimationListener(self))
 anim.addPauseListener(MyAnimatorPauseListener(self))
