Actionscript Tips, for your lucky self

Movie's current directory
- This gets the directory that the swf is in

dir = new String(_root._url);
dirIndex = dir.lastIndexOf("/");
dir = dir.slice(0, dirIndex);
dir = dir+"/";

Easing function for movieclips
- Control alpha, position, and scale easing (rotational easing not yet included)

MovieClip.prototype.ease = function(dx, dy, s, f, da, as, xs, ys, ss) {
  // dx = destination x, dy = destination y, s = speed
  // f = will alpha effect be applied, da = destination/end alpha, as = alpha speed
  // xs = x scale, ys = y scale, ss = scale speed
  this.onEnterFrame = function() {
    this._x += (dx-this._x)/s;
    this._y += (dy-this._y)/s;
    this._xscale += (xs-this._xscale)/ss;
    this._yscale += (ys-this._yscale)/ss;
    if ((this._x == dx and this._y == dy) and (this._xscale == xs and this._yscale == ys) and (f == false or f == null)) {
      delete this.onEnterFrame;
    }
    if (f == true) {
      if (as == null) {
        as = s;
      }
      if (da>=this._alpha) {
        this._alpha += (da-this._alpha)/as;
      } else if (da<=this._alpha) {
        this._alpha -= (this._alpha-da)/as;
      }
      if (this._x == dx and this._y == dy and this._alpha == da) {
        delete this.onEnterFrame;
      }
    }
  };
};
