Moving an object like in MochiAds header

Talking about Flash and Game development.

In the post Wall Dodge – game made from Metro Siberia Underground tutorial I was asked

Emanuele, do you know how to make the follow mouse function that that the sprite uses in mochiads header?

Here it is… it’s so simple I won’t comment it, just play with the delay variable to adjust the spring factor

Mouse.hide();
delay=10;
_root.attachMovie("mousep","mousep",_root.getNextHighestDepth());
_root.attachMovie("mochithing","mochithing",_root.getNextHighestDepth());
mousep.onEnterFrame = function() {
	this._x = _root._xmouse;
	this._y = _root._ymouse;
};
mochithing.onEnterFrame = function() {
	dist_x = mousep._x-this._x;
	dist_y = mousep._y-this._y;
	distance = Math.sqrt(dist_x*dist_x+dist_y*dist_y);
	angle = Math.atan2(dist_y, dist_x);
	speed = distance/delay;
	xspeed = speed*Math.cos(angle);
	yspeed = speed*Math.sin(angle);
	this._x += xspeed;
	this._y += yspeed;
	this._rotation = angle*180/Math.PI
};

Here it is the result
