Senocular's Dissolve Transition

programming flash

I have modified Senocular’s Dissolve transition: :ponder:

http://www.senocular.com/flash/source/?entry=746

to play automatically, changing onMouseDown function to onEnterFrame so the dissolve to happens automatically. However, it only executes once, so I am unable to cycle through more than 2 images. Any insight appreciated.

var frames = 66;
var images = ["flight", "lakes"];

var imagesindex = 0;
var framecount = 0;
var transarea = 0;
var basepoint = new flash.geom.Point(0,0);
var displaybmp = new flash.display.BitmapData(300,196);
var transbmp = new flash.display.BitmapData(300,196);

loadTransBitmap( images[imagesindex] );
displaybmp.draw(transbmp);

this.createEmptyMovieClip("display_mc", 1);
display_mc._y = 25;
display_mc._x = 0;
click_mc.swapDepths(2);
display_mc.attachBitmap(displaybmp, 1);

this.onEnterFrame = function(){
//function onMouseDown(){
    loadTransBitmap( getNextImage() );
    startTransition();
}

function getNextImage(){
    imagesindex++;
    imagesindex %= images.length;
    return images[imagesindex];
}

function loadTransBitmap(id){
    var tempbmp = flash.display.BitmapData.loadBitmap(id);
    transbmp.copyPixels(tempbmp, tempbmp.rectangle, basepoint);
    tempbmp.dispose();
}

function startTransition(){
    framecount = 0;
    transarea = transbmp.width * transbmp.height;
    onEnterFrame = transOnEnterFrame;
}

function transOnEnterFrame(){
    framecount++;
    var amount = transarea * framecount/frames;
    displaybmp.pixelDissolve(transbmp, transbmp.rectangle, basepoint, 0, amount);
    if (framecount >= frames){
        delete this.onEnterFrame;


    }
