ı want loopout offset Expression on path?how can I do that?I want the ball to always land the same way on the stairs

Parent to looping ball to a Null and move the Null.

Thanks for your answer. I want to loopout(offset) Squash and Stretch movement, but I couldn't.

You can create your own loop for path keyframes using modulo (%) math and valueAtTime(), like this equivalent of loopOut("cycle"):

if (numKeys > 1 && time > key(numKeys).time){
  t1 = key(1).time;
  t2 = key(numKeys).time;
  span = t2 - t1;
  delta = time - t2;
  t = delta%span;
  valueAtTime(t1 + t);
}else
  value

By the way, I think "cycle" is what you want, not "offset", but you have other issues to deal with. The main issue is that the duration of your path keframes is different than the position keyframes and the loopOut for the path will quickly get out of sync with the bouncing keyframes. So the timing needs to be driven by the position keyframes. If you delete the last two keyframes of the path animation, that makes the path and position animations the same duration and the above expression might work for you. Play around with it and see what you think.

That's a limitation. loopOut() does not work on paths, only on numerical properties. You have to think of an alternative approach like pre-composing the animation, time-remapping it and looping that.

2 ways to do that

Or just use this expression

valueAtTime(time % key(numKeys).time)
