I want to add a class to an object on a specific position in the timeline.


didn't work. (tree is a timeline)


How can I make something like this?

Thanks in advance: Thomas131

What you're looking for is a TimelineLite/Max method call . 

See the Pen qpsno by bassta (@bassta) on CodePen

- here is a simple codepen how to use it. Here is the code:


tree.call(function() {
    //addClass, toggleClass, or your custom logic.  
}, null, null, 2);

THANKS for answering! And how to define another callback on reversing the animation? I also found out, that this didn't work when the timeline is played multiple times.


Another time thanks in advance: Thomas131

I think I've found an other way by looking into the source:

tree.add(TweenMax.to(function(){},0,{onComplete:function(){$('#map-container').addClass('show-one').removeClass('show-two').removeClass('show-tree').removeClass('show-four');}, onReverseComplete:function(){$('#map-container').removeClass('show-one');}, immediateRender:false}));

Now, reversing is possible, but it pauses the animation.


Another information, that is maybe helpfull for helping: I'm also using Tweendeck


Thanks for helping in advance.

I might be misunderstanding something here about your goal, but couldn't you simply do this:? 

tree.set("#map-container", {className:"+=show-map"});

Remember, CSSPlugin allows you to animate between classes, and you can use "+="/"-=" prefixes to do relative values.
