Hello peeps,

I would like my movie clip to resize my ‘content’ to the stage with easing but am a little unsure where to go from here. Could anybody pls offer some advice or point me in the right dircetion please.
Hrere is an example http://www.nttdata.co.jp/en/index.html
Here is my current code

// Do not scale my movie
Stage.scaleMode = "noScale";
// Align the stage to the top right
Stage.align = "TL";
// define a function to alignobjects on stage resize
alignSite = function () {
// Align the background the middle
with (background) {
_y = Stage.height/2;
_x = Stage.width/2;
}
with (content) {
_y = Stage.height/2;
_x = Stage.width/2;
}
};
resizer = new Object ();
resizer.onResize = function () {
alignSite ();
};
Stage.addListener (resizer);
alignSite ();

thanks
