I don’t understand your code:

```auto
meover.onEnterFrame = function() { // WHAT IS MEOVER??
	trace("olá");
	var acceleration = 10;
	var friction = .80;
	maxX = 760;
	minX = 0;
	ball_mc.moveToMouse = function() { // BAD IDEA TO DECLARE A FCT LIKE THAT
		var xdif = this.targetX-this._x;
		this.xspeed += xdif/this._parent.acceleration;
		this.xspeed *= this._parent.friction;
		this._x += this.xspeed;
		this.checkDistance();
	};
	ball_mc.checkDistance = function() {
		if (Math.abs(this.targetX-this._x)<0.2) {
			this._x = this.targetX;
		}
	};
	ball_mc.onMouseMove = function() {
		if ((_root._xmouse>=minX) && (_root._xmouse<=maxX)) {
			//trace("olá");
			this.targetX = this._parent._xmouse;
			this.onEnterFrame = this.moveToMouse;
		} else {
			this.targetX = this._parent._x;
		}
	};
};

```

Can you explain a bit?
