Yoyo/mirror looping

Feature requests

If would be great IMO to support yoyo/mirror animating, where it loops by reversing direction when it reaches the end instead of restarting at the beginning. It seems pretty common to want to animate the position or rotation back and forth this way but it’s not so convenient ATM… Can manually duplicate and reverse the keys, but that’s not as convenient (e.g. requires manual easing) and doesn’t work with CreateAndStartAnimation.

You can also simply add a callback to onAnimationEnd and set the speed to speed x -1

Thanks I tried it and it works the first time the animation ends, but the callback is only ever called that first time so it stops working after the first loop… Not sure if I did it how you meant thou? :thinking:

This was bothering me as well and I use the duplicated keys approach as well but it would be really nice to have Animation.ANIMATIONLOOPMODE_YOYO :slight_smile:

Here we are: Babylon.js Playground (babylonjs.com)

But I agree with you: do you mind creating an issue on the repo? I will add that YOYO mode after 5.0 release :slight_smile:
