TweenMax.staggerFromTo(counterElement.find('g path'), details.speed, {drawSVG:"0", ease:Sine.easeOut}, {drawSVG:details.percentage+"%", onUpdate: function(){console.log(this)} }); The animation works correctly. The onUpdate is working either.   Now I want to get the current percentage of the drawSVG in the onUpdate. I looked in the this result object, but can't find any variable with current percentage.   How to achieve this?
