Вообщем!
Это в первый кадр:

Код:
MovieClip.prototype.alphamin = function (alpha, speed)
{
this.alpha = alpha;
this.speed = speed;
this.onEnterFrame = function ()
{
this._alpha += (this.alpha - this._alpha) / this.speed;
if (this._alpha < alpha)
{
delete this.onEnterFrame;
}
};
};
MovieClip.prototype.alphamax = function (alpha, speed)
{
this.alpha = alpha;
this.speed = speed;
this.onEnterFrame = function ()
{
this._alpha += (this.alpha + this._alpha) / this.speed;
if (this._alpha > 100)
{
delete this.onEnterFrame;
}
};
};
а это на мувик:

Код:
on (rollOver) {
alphamin (25, 5);
}
on (rollOut) {
alphamax (100, 10);
}
