change time scale on the reverse of a tween (using yoyo) ?

I would like to play the reverse (text is deleted) at twice the speed of when it plays forward (text types in). Is this possible, prehaps using time scale somehow?

Hi,

 

This should work the way you intend:

var type = gsap.timeline({
  repeat: -1
});

var defaults = {
  opacity: 1,
  yoyo: true,
  repeat: 1,
  repeatDelay: 1,
  delay: 1,
  onRepeat() {
    type.timeScale(4);
  },
  onStart() {
    type.timeScale(1);
  }
};

Is a peculiar setup so we have to access the parent timeline on each instance as modifying the timescale of each instance won't work as you expect.

 

Hopefully this helps.

 

Happy Tweening!

Thank you that works great. When you say it's a peculiar setup, is there a better way to do this?

I don't know I'll have to dig deep into it and see if there is another way. Basically what could throw some users off is the fact that the approach is updating the parent timeline's timescale and not the specific instance's timescale. In those cases you should always work with the parent timeline since that's the one actively affecting each tween's playhead. That's something it might take some time to sink in if you're starting with GSAP, but when you get a grasp on the concept it becomes second nature. Timelines are just containers of Tweens with some additional options and properties of course.

 

Good luck with your project!
