Help: trying to modify this dynamic mask

i’m using this dynamic mask, originally coded by the canadian in an old thread, and i’m trying to get it to work in reverse (start with a full image and end with blank)…

if anyone can help me modify this code i’d be very grateful

:hugegrin:

[AS]
_root.maskclip.createEmptyMovieClip(“holder”, _root.maskclip.getNextHighestDepth());
xPos = 0;
yPos = 0;
onEnterFrame = function () {
for (var i = 0; i < 50; i++) {
mySq = holder.attachMovie(“square”, “square” + holder.getNextHighestDepth(), holder.getNextHighestDepth());
mySq._x = xPos;
mySq._y = yPos;
mySq._xscale = mySq._yscale = 30;
mySq.onEnterFrame = function() {
if (this._xscale <= 100) {
this._xscale += 10;
this._yscale = this._xscale;
} else {
delete this.onEnterFrame;
}
};
xPos += 30;
if (xPos > Stage.width) {
xPos = 0;
yPos += 30;
}
}
};
_root.maskclip.mask.setMask(holder);
