I'm having some problems with my code, I setted up the GUI. Now I'm trying to add an expression to the selected properties of a layer an also 2 Slider Control. The button works because I did some tests but the function doesn't work
Code: Select all
myPanel.grp.myTabbedPanel.myTab2.wiggleButton.onClick = function wiggleExpression (){
app.beginUndoGroup("Wiggle");
var myExpr = "wiggle(effect(\"Wiggle Frequency\")(\"ADBE Slider Control-0001\"),effect(\"Wiggle Amplitude\")(\"ADBE Slider Control-0001\"));";
var addSlider1 = app.project.activeItem.selectedLayers.Effects.addProperty("ADBE Slider Control");
addSlider1.name = "Wiggle Frequency";
var addSlider2 = app.project.activeItem.selectedLayers.Effects.addProperty("ADBE Slider Control");
addSlider2.name = "Wiggle Amplitude";
app.project.activeItem.selectedLayers.selectedProperties.expression = myExpr;
app.endUndoGroup();
}
I don't know how to check if a property is selected so you can say me it...

Code: Select all
var activeItem = app.project.activeItem;
if (activeItem != null && activeItem instanceof CompItem) {
if (activeItem.selectedLayers.length != 1 || activeItem.selectedProperties.length != 1) {
alert("You need to select one property first.");
} else {
var theProp = activeItem.selectedProperties[0]; // need to store the selected property before adding the effects as that will change the selection
app.beginUndoGroup("Wiggle");
var myExpr = "wiggle(effect(\"Wiggle Frequency\")(\"ADBE Slider Control-0001\"),effect(\"Wiggle Amplitude\")(\"ADBE Slider Control-0001\"));";
var addSlider1 = app.project.activeItem.selectedLayers[0].Effects.addProperty("ADBE Slider Control");
addSlider1.name = "Wiggle Frequency";
var addSlider2 = app.project.activeItem.selectedLayers[0].Effects.addProperty("ADBE Slider Control");
addSlider2.name = "Wiggle Amplitude";
theProp.expression = myExpr;
app.endUndoGroup();
}
}

It seems to work with transformation properties, like position or rotation, but not for any effect's parameter.
Is there a way to script something that would say "add this expression to the selected effect's param" ?

In Paul's example theProp gets object property, while for the effect parameters you need to grab property group and than a property under that group.
Code: Select all
var comp = app.project.activeItem;
var prop = app.project.activeItem.selectedProperties[0];
var expr = "x = 50;";
if (prop.isEffect == true) {
for (var i = 1; i <= prop.numProperties; i++) {
if (prop.property(i).selected == true) {
prop.property(i).expression = expr;
}
}
} else {
prop.expression = expr;
}
Not sure if you can directly get the selected property under the Effects group... I looped through as a quick work around...
