I've tried the follwing code:

var i = 0;
var tl = new TimelineLite({
onStart:function() {
	if (i <= 2) {
		this.set({}, {}, '+=1.0');
		this.to("#firstitem,#seconditem", 1.0, {autoAlpha: 0,ease:Power1.easeInOut});
},onComplete:function() {
	if (i <= 2) {
tl.from("#firstitem", 1, {autoAlpha: 0, x:100,y:-100,scale:3.0,ease:Power1.easeInOut});
tl.from("#seconditem", 1, {autoAlpha: 0, x:50,y:-50,scale:3.0,ease:Power1.easeInOut});
// ... and so on

But it won't work. The first time OnStart is fired it changes the timlines for all following loops, included loop 3.


Thats what I'm trying to get: After every loop all animated elements has to fade out, except for the last loop. All animated elements should stay. Because of filesize I have to realise this with TimelineLite.


Thanks for your help!


Beste regards

Hi christi4n :)


Welcome to the GreensSock forums.


There would be a few ways to make this happen. My personal approach would be to set up a function with an autoAlpha tween that gets called onComplete and run on the first two passes through. On pass three, that tween isn't run and everything stops. Something like this could work for you:

var i = 0,
    tl = new TimelineLite({onComplete:stayLit});

tl.set("#one, #two", {autoAlpha:1})
  .to("#one", 1, {x:100,y:100})
  .to("#two", 1, {x:100,y:100});

function stayLit() {
  if(i<3) {
    TweenLite.to("#one, #two", 1, {autoAlpha:0, onComplete: function() {tl.restart()}});

Here's a quick CodePen with that solution for you:

Hopefully that helps a bit.


Happy tweening.

PointC's - that helps a lot! Your Solution works great for me.Thanks!

Ohem, thanks for your effort, your solution looks good too, but I have to use TimelineLite.


Again, thanks a lot!


Best regards
