Question

Set animation frame duration with scripting

From within PS, I want to be able to create animation frames from layers and then set the frame duration (frame delay)

This is what I have so far:

var frametime = 1.0 // 1 sec /frame




// create animation frames


createAnimationFromLayers();




// set frame timing


setFrameDuration(frameTime);




function createAnimationFromLayers()


{


  // =======================================================


  var id9070 = stringIDToTypeID( "animationFramesFromLayers" );


  var desc1033 = new ActionDescriptor();


  executeAction( id9070, desc1033, DialogModes.NO );


}




function selectAllFrames()


{


  // =======================================================


  var id3 = stringIDToTypeID( "animationSelectAll" );


  var desc2 = new ActionDescriptor();


  executeAction( id3, desc2, DialogModes.NO );


}




function setFrameDuration(num)


{


  selectAllFrames()


  // =======================================================


  var id4 = charIDToTypeID( "setd" );


  var desc3 = new ActionDescriptor();


  var id5 = charIDToTypeID( "null" );


  var ref1 = new ActionReference();


  var id6 = stringIDToTypeID( "animationFrameClass" );


  var id7 = charIDToTypeID( "Ordn" );


  var id8 = charIDToTypeID( "Trgt" );


  ref1.putEnumerated( id6, id7, id8 );


  desc3.putReference( id5, ref1 );


  var id9 = charIDToTypeID( "T   " );


  var desc4 = new ActionDescriptor();


  var id10 = stringIDToTypeID( "animationFrameDelay" );


  desc4.putDouble( id10, num ); //num (duration in seconds)


  var id11 = stringIDToTypeID( "animationFrameClass" );


  desc3.putObject( id9, id11, desc4 );


  executeAction( id4, desc3, DialogModes.NO );


}

What I want to know is this

- How can you open the animation window in scripting ( as it script will fail with it closed) - might have to add a try/catch for it otherwise

- Is it possible to loop over the animation frames like this: (I don't know the syntax I'm guessing)

for (var i = 0; i < numOFrames; i++)


{


    app.activeDocument.animation.frames = 1.0;


}

  1 for (var i = 0; i < numOFrames; i++) 

  2 { 

  3     app.activeDocument.animation.frames = 1.0; 

  4 } 

What do you want to accomplish by this?

Select or determine a frame – then what?

This would select the second frame and set it to 0,1s :

// =======================================================

var idslct = charIDToTypeID( "slct" );

    var desc2 = new ActionDescriptor();

    var idnull = charIDToTypeID( "null" );

        var ref1 = new ActionReference();

        var idanimationFrameClass = stringIDToTypeID( "animationFrameClass" );

        ref1.putIndex( idanimationFrameClass, 2 );

    desc2.putReference( idnull, ref1 );

executeAction( idslct, desc2, DialogModes.NO );

// =======================================================

var idsetd = charIDToTypeID( "setd" );

    var desc3 = new ActionDescriptor();

    var idnull = charIDToTypeID( "null" );

        var ref2 = new ActionReference();

        var idanimationFrameClass = stringIDToTypeID( "animationFrameClass" );

        var idOrdn = charIDToTypeID( "Ordn" );

        var idTrgt = charIDToTypeID( "Trgt" );

        ref2.putEnumerated( idanimationFrameClass, idOrdn, idTrgt );

    desc3.putReference( idnull, ref2 );

    var idT = charIDToTypeID( "T   " );

        var desc4 = new ActionDescriptor();

        var idanimationFrameDelay = stringIDToTypeID( "animationFrameDelay" );

        desc4.putDouble( idanimationFrameDelay, 0.100000 );

    var idanimationFrameClass = stringIDToTypeID( "animationFrameClass" );

    desc3.putObject( idT, idanimationFrameClass, desc4 );

executeAction( idsetd, desc3, DialogModes.NO );

Does this have any relevance for your undertaking?

    Is the important thing not that "Create Frame Animation" has been performed rather than for the Timeline Panel to be open?
