Is there a way to reference the item's index from the vars. For example:

TweenMax.staggerFrom($items, 1, {
  y: -100 * itemIndex
}, 0.5);

I can calculate the index like this: $items.index(this.target) but it seems like it's something that TweenMax should expose directly.

The stagger methods require that all animated properties are the same for each element that is being animated. The important focus of these methods is the ability to conveniently offset the start times. If you need random or incremented values to animate from, the solution is to use a loop

$(".box").each(function(index, element){
  TweenLite.from(element, 0.5, {x:(index+1) * 200, opacity:0, delay: index * 0.2})



In theory, what you propose is a nice idea, however finding a practical implementation is non-trivial.

My guess is that any valid solution is going to be just as much code as the loop or perhaps far more cryptic. 


We're certainly open to ideas though. Keep 'em coming.
