I am trying to make a rotation loop on my images only when they are in viewport. I want to pause this loop when they re out of the viewport. I am trying to use getClientBoundingRect to detect the position of my elements and I try to trigger the function when they are visible. The issue is that it only runs once. Console log is showing me that the viewport detection works fine, but the TweenMax.to animation is not working like it should. 

I do not want to use ext. libraries for viewport detection.

Any help is much than appreciated guys!

Thanks

Hey @Juraj,

 

Welcome to the GreenSock Forum.

 

You could play() and pause(0) a timeline which is paused.
Here's an example with intersectionObserver

Happy tweening ...

Thank you Mikel, this works just perfect. Have a great Sunday ;)

@mikel i have one other little request. Imagine that i d like to use this animation on the page multiple times.

Your code works great for one. But every single time the object is in the viewport (no matter which one), it runs the animation for all of the objects on the page. Any idea of how to make this work only for the item visible in the viewport?

Many thanks man

You'd need to create a timeline for each element and have the target of the timeline animations be one specific element. I'd usually attach the timeline to the element itself so that inside of the Intersection Observer function you could say entry.target.action.play();

 

Here's an example pulled from another thread:
