Código PHP:
MovieClip.prototype.alpha = function(vel, to) {
this.vel = vel;
this.to = to;
this.alpha_init = this._alpha;
this.onEnterFrame = function() {
updateAfterEvent();
if (this.to != undefined && this.vel != undefined) {
if (this.to>this.alpha_init) {
if (this._alpha<=100) {
this._alpha += this.vel;
} else {
this.onEnterFrame = null;
}
} else {
if (this._alpha>this.to) {
this._alpha -= this.vel;
} else {
this.onEnterFrame = null;
}
}
} else {
}
};
};
gracias!
