Hi, I want a Timeline to skip to half way through on repeat


So the first play through starts from 0, but on every play through after that, I want it to start form halfway


Is that possible? 

var tl = new TimelineMax({repeat:-1, repeatDelay:2});

tl.to("#circle", 4, {x:400})

Hello @friendlygiraffe


You can use the onRepeat special parameter inside your TimelineMax() constructor since your using repeat.


See the Pen wdZeNp by jonathan (@jonathan) on CodePen


TweenLite.defaultEase = Power0.easeNone;

var tl = new TimelineMax({
  onRepeat: seek2

tl.to("#circle", 4, {x:400});

function seek2(){


Happy Tweening :)

Thanks Jonathan, that's really handy 


I am actually using it within a nested Sequence, and I noticed the onRepeat method doesn't behave correctly when nested 


TweenLite.defaultEase = Power0.easeNone;

var textAnims = new TimelineMax({
  onRepeat: seek2

textAnims.to(".red", 0.5, {x:400,  autoAlpha:0.3})
.to(".red", 0.5, {x:0,  autoAlpha:1})
.to(".green", 0.5, {x:400,  autoAlpha:0.3})
.to(".green", 0.5, {x:0,  autoAlpha:1})
.to(".blue", 0.5, {x:400,  autoAlpha:0.3})
.to(".blue", 0.5, {x:0,  autoAlpha:1})

function seek2(){

var tl = new TimelineMax();
tl.add(textAnims, 0.0)

smoothChildTiming is a tough concept to describe with words. I don't think I ever did a video.


Blake, thanks for the suggestion but I'm not sure that demo on its own in its current state will illustrate the issue as it clear as it should. Probably needs to be thought out a bit more with an easy way to compare smoothChildTiming:true to false. I've had some ideas for a video but it would require some visuals that would take a while to create properly. For instance, creating a visual representation of "the tween would flip in place, keeping its startTime consistent. Therefore the playhead of the timeline would now be at the tween's 25% completion point instead of 75%." is a bit of a challenge.
