TweenAccessor<Sprite>

SpriteTweenAccessor

// Arguments are (1) the target, (2) the type of interpolation, 
// and (3) the duration in seconds. Additional methods specify  
// the target values, and the easing function. 

Tween.to(mySprite, Type.POSITION_XY, 1.0f).target(50, 50).ease(Elastic.INOUT);

// Possibilities are:

Tween.to(...); // interpolates from the current values to the targets
Tween.from(...); // interpolates from the given values to the current ones
Tween.set(...); // apply the target values without animation (useful with a delay)
Tween.call(...); // calls a method (useful with a delay)

// Current options are:

yourTween.delay(0.5f);
yourTween.repeat(2, 0.5f);
yourTween.repeatYoyo(2, 0.5f);
yourTween.pause();
yourTween.resume();
yourTween.setCallback(callback);
yourTween.setCallbackTriggers(flags);
yourTween.setUserData(obj);

// You can of course chain everything:

Tween.to(...).delay(1.0f).repeat(2, 0.5f).start();

// Moreover, slow-motion, fast-motion and reverse play is easy,
// you just need to change the speed of the update:

yourTween.update(delta * speed);

Timeline.createSequence()
    // First, set all objects to their initial positions
    .push(Tween.set(...))
    .push(Tween.set(...))
    .push(Tween.set(...))

    // Wait 1s
    .pushPause(1.0f)

    // Move the objects around, one after the other
    .push(Tween.to(...))
    .push(Tween.to(...))
    .push(Tween.to(...))

    // Then, move the objects around at the same time
    .beginParallel()
        .push(Tween.to(...))
        .push(Tween.to(...))
        .push(Tween.to(...))
    .end()

    // And repeat the whole sequence 2 times
    // with a 0.5s pause between each iteration
    .repeatYoyo(2, 0.5f)

    // Let\'s go!
    .start();
