...so that I can add the next image. and use a tween alpha to show it. If you test this, (just rename any images by the image names I use and export to as3 from library). You can see that the perlinnoise is continually existing in the background. For simplicity and testing, I'm tweening only two halves of an image as I'm testing, but actually I would like to eventually tween many parts (copyPixels) of the original image.
I'm trying to get this to work because Tween doesn't work when you're trying to tween only one index of an array (so I can time each index differently), even if I name each index item in the array.
Interestingly enough when I use the loop and set the x property of the new Rectangle to ix the bit of code below works to stop the perlin noise. But as soon as I remove the loop, the flag.fillRect(flag.rect, 0); doesn't work.
if (newMC2.alpha == 1) {
found = true;//stage.removeChildAt(0);stage.removeChild(flag);ary.splice(0);
break loop;
//break scloop;
//break noise;
flag.fillRect(flag.rect, 0);
}//END if

OR does any one know the math to move each pixel, so that the whole image waves like a flag, without perllinnoise, so that I can start and stop the waving when desired.

....and I also forgot to add the found = true; at the end of the innemost nested else, and that fixed the perlinnoise from progressively changing as it looped through the main timer and entered the wind function.
