Class help

I built my first simple class which just makes a movieclip move around randomly on the stage. I wanted to know if the “class” experts can take a look at my code and let me know how I can improve.

I want it so that it is the most efficient code and can be applied to any movieclip that I want as easy as possible.

Thanks.

Code in my flas:


import com.randomMotion.randomMotionController;

Stage.align = "CM";
Stage.scaleMode = "noScale";

var rmc:randomMotionController = new randomMotionController(circle_mc, random(500), random(350), 5);

Class:


import mx.utils.Delegate;

class com.randomMotion.randomMotionController
{
    /*
     * ==================================================================================================== 
     * PRIVATE VARIABLES
     * ====================================================================================================
     */
    private var _mc:MovieClip;
    private var _newX:Number;
    private var _newY:Number;
    private var _speed:Number;
    
    /*
     * ==================================================================================================== 
     * CONSTRUCTOR
     * ====================================================================================================
     */
    public function randomMotionController($mc:MovieClip, $startX:Number, $startY:Number, $speed:Number)
    {
        this._mc = $mc;
        this._newX = $startX;
        this._newY = $startY;
        this._speed = $speed;
        
        this._mc.onEnterFrame = Delegate.create(this, moveBall);
    }
    
    /*
     * ==================================================================================================== 
     * PRIVATE FUNCTIONS
     * ====================================================================================================
     */
    private function moveBall( Void ):Void
    {
        this._mc._x += (this._newX - this._mc._x) / _speed;
        this._mc._y += (this._newY - this._mc._y) / _speed;
        
        if (Math.round(this._mc._x) == this._newX && Math.round(this._mc._y) == this._newY)
        {
            this._newX = random(500);
            this._newY = random(350);
        }
    }
    
    /**
     * ==================================================================================================== 
     * CLOSE CLASS
