Problem migrating onClipEnter frame and angle property in as 3.0

Hello,
I’m trying to migrate a simple actionscript 2.0 app to 3.0 and I’m having some problems finding equivelents of the onEnterFrame methods and the angle property in as 3.0.

In this section, I need to have the t movieClip variable onEnterFrame method call the mover function:


for(var i:Number = 0; i < numberOfItems; i++)
{
    var t = attachMovie("icon", "icon"+i, i+1);
    t.angle = i * ((Math.PI*2)/numberOfItems);
    t.onEnterFrame = mover;
}        

In this section, I need to find an as 3.0 equivelent to the this.angle property:


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

Any ideas?

Thanks,
Eric
