[flashpro] Fade scripter for objects

[pete otaqui]

The only issue with Denis's method is one of memory consumption and
the flash scope chain.  Although in this particular example the effect
is probably negligble, you can find out more about the problems with
defining functions inside functions here:

An alternative method might be like this:


function fade(_mc,maxi) {
  _mc.maxi = maxi;
  _mc.onEnterFrame = fademe;
}

function fadme() {
  if ( math.round(this._alpha)==this.maxi ) {
    trace("stopped");
    delete this.onEnterFrame;
  } else {
    this._alpha += (this._maxi-this._alpha)/10;
    trace(this._alpha);
  }
}



Cheers

Pete
