Function + variables all in actions frame

1

The following code is what I have in an actions frame:


function FLOAT_engine() {
    this._x = this.cenX+Math.sin(this.angleX)*this.rangeX;
    this._y = this.cenY+Math.sin(this.angleY)*this.rangeY;
    this.angleX += this.xspeed;
    this.angleY += this.yspeed;
}
floaty.onEnterFrame = FLOAT_engine;
floaty2.onEnterFrame = FLOAT_engine;
etc.

And in my movieclip (floaty) I have the variables:


onClipEvent (load) {
    cenX = this._x;
    cenY = this._y;
    angleX = 0;
    angleY = 0;
    rangeX = 5;
    rangeY = 5;
    xspeed = .05;
    yspeed = .06;
}

How would I got about re-writing this code so it is all in the actions frame? The way that I have it set up now, I’d have to paste the variables into every movieclip. It would be a pain if I ever wanted to change the values. ;( Thanks in advance.
