Show a property using Extendscript

[Fabrice Leconte]

Hello, you can use

rd_GimmePropPath.jsx

I just came up with this hack:

// prop we want to reveal:
prop  =  app.project.item(1).layer("Shape Layer 1")("Contents")("Shape 1")("Contents")("Path 1")("Path");
// reveal in timeline Hack:
originalExpression = prop.expression;
prop.expression= "1/0"; // create an expression error
//reveal expression errors:
app.executeCommand( app.findMenuCommandId("Reveal Expression Errors") );
$.sleep(1); // wait 1 ms
// reset expression to previous value
prop.expression = originalExpression;

It does seem to hide the properties that were previously visible though…

Thanks for your effort on this. Running this code exposes the path property. Is there any way I can show its parent – Path 1 and make its state as selected? Fingers crossed.

[Avinash Ramanath]

Thanks but I wanted the Path 1 attribute exposed so that I can select its leads and modify it

[Filip Vandueren]

No, the hack only works on properties that have canSetExpressiom=true

And it is a hack, there’s no official way to show or hide anything in the timeline via scripting.

[Filip Vandueren]

What do you mean by “set its leads”?

[Avinash Ramanath]

OK, thanks very much for trying. I will use this hack sometime in the future.

I modified Filip’s code a bit to support multiple properties. You just need to pass as many properties as you need into revealProperty function as arguments

Here’s small working example:

var curComp = app.project.activeItem;
var curLayer = curComp.selectedLayers[0];
 
revealProperty(curLayer.opacity, curLayer.scale);
 
function revealProperty(){
 var originalExpressions = [], prop = arguments;
 for(i=0; i<prop.length; i++){
  originalExpressions.push(prop[i].expression);
  prop[i].expression= "1/0";
 }
 app.executeCommand(app.findMenuCommandId("Reveal Expression Errors"));
 $.sleep(1);
 for(i=0; i<prop.length; i++){
  prop[i].expression = originalExpressions[i];
 }
}
