So my issue is that I want my images to get smaller as they go to the back, and unlike the carousel in the tutorial, I don't want them to go up on the Y axis— I'd like them to stay level horizontally but get smaller as they recede. The code in the tutorial I'm using only goes over how to do this by adjusting radiusY.

If someone could help me out with a snippet of code for this! My current code is:

var numOfItems:Number = 4;
var radiusX:Number = 250;
var radiusY:Number = 5;
var centerX:Number = Stage.width / 2;
var centerY:Number = Stage.height / 2;
var speed:Number = 0.05;

for(var i=0;i<numOfItems;i++)
{
var t = this.attachMovie("item","item"+i,i+1);
t.angle = i * ((Math.PI*2)/numOfItems);
t.onEnterFrame = mover;
}

function mover()
{
this._x = Math.cos(this.angle) * radiusX + centerX;
this._y = Math.sin(this.angle) * radiusY + centerY;
var s = this._y /(centerY+radiusY);
this._xscale = this._yscale = s*100;
this.angle += this._parent.speed;
this.swapDepths(Math.round(this._xscale) + 100);
}

this.onMouseMove = function()
{
speed = (this._xmouse-centerX)/5500;
}
