Achieving the typewriter effect

var doc = fl.getDocumentDOM();

doc.breakApart();
doc.distributeToLayers();
doc.selectAll();


var obs = doc.selection;
doc.getTimeline().insertFrames( obs.length * 2, true, 1); 

var tl = doc.getTimeline();
var total = obs.length;
var i = total + 1;


while( i-- ){
    tl.setSelectedLayers( total - i, true );
    tl.cutFrames(0);
    tl.pasteFrames( i * 2 );
    tl.clearFrames(0, (i * 2));

}

Correct answer kglad

var doc = fl.getDocumentDOM();

doc.breakApart();
doc.distributeToLayers();
doc.selectAll();

var obs = doc.selection;
doc.getTimeline().insertFrames( obs.length * 2, true, 1);

var tl = doc.getTimeline();
var total = obs.length;

for(i=1;i<total;i++){
tl.setSelectedLayers( total - i, true );
tl.cutFrames(0);
tl.pasteFrames( i * 2 );
tl.clearFrames(0, (i * 2));
}

    oops, my error.  use:

     

    var doc = fl.getDocumentDOM();

    doc.breakApart();
    doc.distributeToLayers();
    doc.selectAll();

    var obs = doc.selection;
    doc.getTimeline().insertFrames( obs.length * 2, true, 1);

    var tl = doc.getTimeline();
    var total = obs.length;

    for(i=1;i<=total;i++){
    tl.setSelectedLayers( total - i, true );
    tl.cutFrames(0);
    tl.pasteFrames( i * 2 );
    tl.clearFrames(0, (i * 2));
    }

       tl.setSelectedLayers( total - i, true );

     

    is going to be out of range when i=0.  ie, don't use while loops unless you really know what you're doing and are certain you're not going to make a mistake.  eg, i never use while loops because i know i make mistakes.
