How to scale from the middle in Actionscript

Hello all.

I have the following code:

function box1ScaleUp(e:MouseEvent):void {

box1.scaleX = 1.5;

box1.scaleY = 1.5;

box2.x = 80

box3.x = 135

}

Now, when it scales, it scales from the movieclip var registration point of 0,0. So when it scales, it appears to grow in two directions (down and to the right)

Is there a way to have it scale from the center of the box so that it scales equally in all 4 directions?

Thanks in advance!

    you can change your reg point to box1's center or you can add box1 to a parent and offset it and scale its parent:

    var p:MovieClip=new MovieClip();

    box1.parent.addChild(p)

    p.x=box1.x+box1.width/2;

    p.y=box1.y+box1.height/2;

    box1.x=-box1.width/2;

    box2.y=-box1.height/2;

    p.addChild(box1);

    p.scaleX=1.5;

    p.scaleY=1.5;

    Thanks!

    Haha, I totally didn't think of changing the reg point in the symbol. DUH!
