offsetting mask shape like using loopOut(“offset”)

[David Cabestany]

Is there a way to tweak this expression to make it work with a shape layer instead? I tried replacing mask with path and then the name of the path but all I got is the following error:

function “path” is undefined.

What would be the name of the function in a shape layer, then, specifically the path?

Best,
David.

If you’re apply the expression to the shape layer’s path, this should be all you need:

control = effect(“Slider Control”)(“Slider”);
t = key(numKeys).time;
valueAtTime(t*control/100)

Thanks a lot Dan.

// In AE 2020, to offset path value between two linear keyframes, I use:

var pProp = thisProperty;

if (pProp.numKeys > 1 && time > pProp.key(pProp.numKeys).time) {

var t1 = pProp.key(1).time;

var t2 = pProp.key(pProp.numKeys).time;

var span = t2 – t1;

var n = Math.floor((time – t1) / span); var t = (time – t1) % span;

var pStart = pProp.points(t1); var pEnd = pProp.points(t2);

var pNow = pProp.points(t1 + t);

var newPoints = [];

for (var i = 0; i < pNow.length; i++) {

var dx = (pEnd[i][0] – pStart[i][0]) * n;

var dy = (pEnd[i][1] – pStart[i][1]) * n;

newPoints.push([pNow[i][0] + dx, pNow[i][1] + dy]);

}

createPath(newPoints, pProp.inTangents(t1 + t), pProp.outTangents(t1 + t), pProp.isClosed());

} else {

value;
