 'ValueAtTime' along With 'Dan Ebberts Over Shot'! on Aug 27, 2014 at 7:15:24 pm

This maybe a very noob question..
i want to make a layer follow the rotation of other layer using 'ValueAtTime' expression. and it worked just fine.

But i also want this layer to over shot using the great expression of 'Dan Ebberts'
so my expression looked like this

```thisComp.layer("Scound Squar").transform.rotation.valueAtTime(time -0.04) +value freq = 3; decay = 5; n = 0; if (numKeys > 0){ n = nearestKey(time).index; if (key(n).time > time) n--; } if (n > 0){ t = time - key(n).time; amp = velocityAtTime(key(n).time - .001); w = freq*Math.PI*2; value + amp*(Math.sin(t*w)/Math.exp(decay*t)/w); }else value```

But it didn't work this way, the 'valueAtTime' get ignored..
I appreciate any help..

That would be more like this:

``` p = thisComp.layer("Scound Squar").transform.rotation; tDelay = time -0.04; val = p.valueAtTime(tDelay); freq = 3; decay = 5; n = 0; if (p.numKeys > 0){ n = p.nearestKey(tDelay).index; if (p.key(n).time > tDelay) n--; } if (n > 0){ t = tDelay - p.key(n).time; amp = p.velocityAtTime(p.key(n).time - .001); w = freq*Math.PI*2; val + amp*(Math.sin(t*w)/Math.exp(decay*t)/w); }else val ```

Dan!! Thank you veeery very Much!

hello again!! so i tried to work something on my own,
so i added '+value' to the end of the equation so i can use the key-frames to animate the child-layer separately...

and it kinda worked! but sadly with no over-shot if animated with key-frames..

```p = thisComp.layer("Main Squar").transform.rotaion; tDelay = time -0.04; val = p.valueAtTime(tDelay); freq = 3; decay = 5; n = 0; if (p.numKeys > 0){ n = p.nearestKey(tDelay).index; if (p.key(n).time > tDelay) n--; } if (n > 0){ t = tDelay - p.key(n).time; amp = p.velocityAtTime(p.key(n).time - .001); w = freq*Math.PI*2; val + amp*(Math.sin(t*w)/Math.exp(decay*t)/w)+value; }else val```
