Hi there,


Does anyone know how I would apply roundprops to the following tween?, I can't figure it out.


tl.tweenFromTo(tl.time(), tl.getLabelBefore(), {onComplete: function(){allowScroll = true;}});

Interesting question, and probably the first time its come up. I was initially doubtful it would work, but it does and it should  :-P  


The most important thing to note is that tweenFromTo() creates a tween that tween's the time() of a timeline.

So the trick is to tell roundProps to round the "time" like so

tl.tweenFromTo(0, 10, {roundProps:"time"});

So that will advance the timeline and round time to 1-second intervals

Is that what you wanted?

Also, also if you want to have more control over this stepped / jumpy type of animation a SteppedEase is the way to go:

 tl.tweenFromTo(0, 10, {ease:SteppedEase.config(50)});



You can easily change the number of steps so you have much more flexibility than rounding the time() to seconds.

Thanks, thats perfect. It's actually for a video scroll and scrub website. Might be having performance issues as it's trying to target frames of the video or times that essentially don't exist. This should help, thanks.
