Getting the 3d carousel right fading out

Hello All,
I am trying to get the 3d carousel to “Fade out and In” dynamic with AS.
I have got a mover function and think i have to add lines here but do not wich…

I need help the sample i am trying to build is bascily the same as on

The function i have is :
function mover()
this._x = Math.cos(this.angle) * radiusX + centerX;
this._y = Math.sin(this.angle) * radiusY + centerY;
var s = (this._y - perspective) /(centerY+radiusY-perspective);
this._xscale = this._yscale = s*100;
this.angle += this._parent.speed;
this.swapDepths(Math.round(this._xscale) + 100);
