wow, i was sure i tried that at the beginning…
maybe i needed some operation to be made at the same time to the layers… anyway, it works now,
really appreciate your help!

This will be great to add thanks.
but the problem wasn’t the expression. putting expressions works great for all layers and all properties, the valueAtTime line doesn’t.
what am i missing?

[Tal Arbiv]

i tried it and it breaks…

something about that valueAtTime method stops the loop that goes through the layers

var myComp = app.project.activeItem;
var sellayers = myComp.selectedLayers;
var selprop = myComp.selectedProperties;

for (i=0; i <= sellayers.length-1; i++){
for (p=0; p <= selprop.length-1; p++){
selprop[p].expression =("1"); //WORKS GREAT
alert (selprop[p].valueAtTime(0,false)); // DOSNT WORK breaks the loop after the first layer
}
}

Thank you so much Dan!

yes its scripting…

The second question i had was how can i tell how many dimensions a property has ?
i’m applying an expression to layers and i want the expression to change according to the dimensions…

lets take wiggle for example
if there is a better way to do this please share…

Thanks a lot again!

var expression1 = "wiggle (10,10)";
var expression2 = "w=wiggle (10,10);[w[0],w[0]]";
var expression3 = "w=wiggle (10,10);[w[0],w[0],w[0]]";

for (i=0; i <= sellayers.length-1; i++){
for (p=0; p < = selprop.length-1; p++){
//missing query
selprop[p].expression = //expressionX;
}

Excellent,
Thanks

[Tal Arbiv]

YES! great!
that seem to work.
thank you!

[Tal Arbiv]

Thanks a lot, but no, this changes the ratio.

lets say you have a layer and its scale is something like [-30 , 100] if you parent it to a null you can wiggle it uniformly with [w[0],w[0]] .
i’m looking for that same result with a single expression without using a null….
