looping a path's movement?

[Michalis5CC4]

Is there a way to loopOut a path in AE 2020?

[Byron Cortez]

You do not give much information but if you mean to follow a Path as if it were a path on a map, yes there is, there are several ways to do it, you could try to do the animation in position first, you apply the LoopOut expression so that the movement is repeated and if it is necessary to apply an Auto-Orient from the Layer / Transform menu.

I've a shape made with pen tool and want it to change it's form(path) continuously looping...

I added 3 keyframes and the expression of loopOut("continuous") but I get an error

I can't tell from your question if you're trying to do loopOut("cycle") or loopOut("continue"). I can't think of a way to do the "continue" version, but you can wrangle your own version of "cycle" by using valueAtTime(), like this:

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

Αs you can see the shame below, it is supposed to change its form continuously.

Did you try my suggestion above, to see if it does what you want?

[Michalis5CC4]

To be honest it seems to be a bit advanced for me. I will study the expression and inform you the sooner.

Thank you

[Dan Ebberts]

To try it, you just need to copy it and paste it into your path property. It will either do what you need or it won't. No study required.  🙂

Oooh it's working...but I cannot understand it.

Can you please explain it a bit or link me a tutorial about it in order to learn?

Thank you in advance mate
