Pan and zoom MovieClip

programming flash
1

Hello,

I’m made a map and I want to zoom in and out. The second thing I want is to make a bounding around my MovieClip.

function initDragger(zijde2:MovieClip):void
{
    zijde2.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
    zijde2.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler);
}

function mouseDownHandler(e:MouseEvent):void
{
    e.currentTarget.startDrag();
}
function mouseUpHandler(e:MouseEvent):void
{
    e.currentTarget.stopDrag();
}


initDragger(zijde2);

plus.addEventListener(MouseEvent.CLICK, onImageClick);

min.addEventListener(MouseEvent.CLICK, onImageClick2);

function onImageClick2(Event:MouseEvent):void
{
    if (zijde2.scaleX > .05) {
        zijde2.scaleX*=.5;
        zijde2.scaleY*=.5;
    }
}

function onImageClick(Event:MouseEvent):void
{
zijde2.scaleX*=2;
zijde2.scaleY*=2;
}

This is my code so far and I can zoom in and out but I can keep going and going. I want that he stops after 200% or something and when he is 100% you cant zoom out more. Also I want a bounding so I cant move the MovieClip outside his own stage height and width.

Is there someone that can help me with this because I’m really stuck at this point.

Thanks
