That was it! Second option works like a charm. I got the idea. And in addition, regarding what I've called lag, it dissapeared... Thank you so much, Jack!

Ok, I understand. So forget my example and the lag. Let's focus on the GSAP example, the ferris. Just I'm trying to do a infinite reverse loop, that currently it isn't implemented. And without TimelineMax, only a simple TweenMax instance. My first attempt was to update the rotation angle sign each time that the reverse /play button was pressed, without success. Something similar to this: tl.invalidate() tl.vars.css.rotation= 360; tl.play(); My best attempt is this one, redefining the tween effect every time the button is pressed. However, first the progress slider doesn't change the direction, and second, if you press several consecutive times, the tween appears to decelerate.

Ok, I've tried to simplify and isolate the important code: http://codepen.io/MrFrames/pen/zqRrJo?editors=1010 I'm using highcharts to draw the sine wave. Select counterclock wise, the animation starts. Set the speed slider to the maximum. Check the sine wave: when it goes up upwards (around amplitude -2.5), suddenly it appers a small distortion in the wave (closer look), that is what I've called "lag", that coincides when TimelineMax is restarted. However, if you use only Tweenmax, that lag in the sine wave doesn't appear: http://codepen.io/MrFrames/pen/mPjQao?editors=1010 I hope that you can check this issue in the examples. I have basically token the ferris example and modified it. The magnitude of the distortion could be discussed; it is true that is very small, but there it is. In the whole project, with much more info and curves, that lag is more evident. And, of course, another engine that is not GSAP is not and option! At least, I am satisfied if you say that there are possibilities to make infinite reverse loops, becasue there are no examples anywhere, I will try it! And apologize for the code, these are my first steps in html, javascript, GSAP

Hello, First of all thank very much for this incredible tool! I am an absolute noob developing animations (and web pages) and thanks to GSAP I've had to do so little efforts to learn . I am trying to rotate a image and control the animation, very similar to the Ferris example: http://codepen.io/GreenSock/pen/wBbKs?editors=1010 The user can select if the rotation is clockwise or counterclockwise. This is my question: is it possible to do a infinite reverse loop without TimelineMax, just a TweenMax instance? The problem is that, related with this rotation, I am drawing a sine wave based on the tween progress. However, when TimelineMax reaches onReverseComplete or onComplete, a small lag can be checked in the sine wave drawing, distorting the result. I do not find this lag if I use only TweenMax, but I am not able to do a reverse infinite loop only with TweenMax... Thank you in advance!!
