Create an Animated Mask For a Layer

Hi All,
I am trying to automate a process and I need to create an animated mask on every layer I import.
I don't know if this is possible, but is there a way to create a mask using JSX? If so, how do I animate it?
Thanks

Hmmm, almost.
Code: Select all
// create square mask
var newMask = mySolid.Masks.addProperty("Mask");
newMask.inverted = true;
var myMaskShape = newMask.property("maskShape");
var myShape = myMaskShape.value;
myShape.vertices = [[5,5],[5,45],[45,45],[45,5]];
myShape.closed = true;
myMaskShape.setValue(myShape);
Does anyone know what the code syntax is for animating the
mask?
Code: Select all
myPosition.setValueAtTime(4,[80,30]);
Here is position, what is the equivalent for
mask verticies?
Thanks!

more experimenting has lead to this.
Code: Select all
myShape.vertices = [[0,0],[w,0],[w,h],[0,h]];
myShape.closed = true;
myMaskShape.setValueAtTime(0,myShape);
offset = 50;
myShape.vertices = [[0+offset,0],[w+offset,0],[w+offset,h],[0+offset,h]];
myShape.closed = true;
myMaskShape.setValueAtTime(1,myShape);
It looks like setValueAtTime is all you need.
