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()Thread
JJValueAnimator uses the current thread.
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))
