XML Gallery: Thumbnail Mask Targeting

programming flash
1

Hi,

I am in the process of making my portfolio site but am having some trouble animating masks which mask each thumbnail…I can’t target individual masks in my script, only one mask. I think the solution will be pretty simple but I don’t have the skillz to do it!! Can anyone help?

Here is my thumbloaded function:

    var my_thumb:Loader = Loader(e.target.loader); 
    sprite = new MovieClip(); 
    var shape:Shape = new Shape();
	var dropShadow:DropShadowFilter = new DropShadowFilter();
	
	mask_mc = new Mask();
	mask_mc.x = e.target.loader.x+115;
	mask_mc.y = e.target.loader.y+75;

	my_thumb.mouseEnabled=false;
 //   shape.graphics.lineStyle(1, 0xffffff);
	shape.graphics.beginFill(0xffffff);
    shape.graphics.drawRect(e.target.loader.x, e.target.loader.y, e.target.loader.width, e.target.loader.height); 
	shape.graphics.endFill();
	dropShadow.color = 0x111111;
	dropShadow.blurX = 5;
	dropShadow.blurY = 5;
	dropShadow.angle = 0;
	dropShadow.alpha = 0.9;
	dropShadow.distance = 0;
	shape.filters = [dropShadow];
	sprite.addChild(shape); 
	
    sprite.addChild(my_thumb);
	
	sprite.addChild(mask_mc);
	my_thumb.mask = mask_mc;
	
	TweenMax.to(my_thumb, 0, {colorMatrixFilter:{colorize:0xdddddd, amount:1}});
    container_mc.addChild(sprite); 
	
	my_tweens[Number(my_thumb.name)]=new Tween(sprite, "alpha", Regular.easeInOut, 0.5,1,0.5, true); 

    my_thumb.contentLoaderInfo.removeEventListener(Event.COMPLETE, thumbLoaded); 
}

and my onOver function for the thumbnail over:

function onOver(e:MouseEvent):void { 
    var my_thumb:Sprite= Sprite(e.target);
	TweenMax.to(my_thumb.getChildAt(1), 1, {colorMatrixFilter:{amount:1}});
	[COLOR="Red"]TweenLite.to(mask_mc, 0.3, {width:190, height:110,ease:Circ.easeOut});[/COLOR]
}

I am so close to getting where I want so I will be really grateful for help.
Thanks
