    where to put continuously executing script


    i'm new to flash but not to programming...
    i'm trying to create a button-like effect whereby an image becomes brighter and brighter (alpha goes from 0-->100) the longer the mouse stays over it. and conversely, the button fades away slowly once the user moves his mouse away from it.

    i'm coming from a background of programming in lingo, where i would have just put an if then type of statement in the first frame, which would then be executed all the time.

    i have noticed that in flash, my script in the first movie frame (below) is getting executed once only.

    mc_hit01.onRollOver = function () {
    mc_hit01._alpha = Math.min (100, mc_hit01._alpha + 5);

    it is not executing WHILE i am over the button, but only once each time i pass over it.

    is there a way to make a flash movie 'loop' the way it would in director ? if not, how/where do i put code that should continuously execute ? in the movie clip itself ? (would prefer to keep all my scripts in one place, the first frame, if possible, but if that's the only way to do it...)

    On the fifth floor.
    mc_hit01._alpha = 0;
    mc_hit01.onEnterFrame = function() {

    t = mc_hit01.hitTest(_xmouse, _root._ymouse);
    t ? (this._alpha<=100 ? this._alpha++ : this._alpha=100) : (this._alpha>0 ? this._alpha-- : this._alpha=0)


    mc_hit01.onRollOver = function(){
    t = true;
    mc_hit01.onRollOut = function(){
    t = false;
    mc_hit01.onEnterFrame = function(){
    t ? (this._alpha<=100 ? this._alpha++ : this._alpha=100) : (this._alpha>0 ? this._alpha-- : this._alpha=0);

    Maybe something like this....


    _root.clip._alpha = 0;
    myFader = function (myTarget, alpha) {
    this.onEnterFrame = function() {
    if (alpha == true && myTarget._alpha>=0) {
    myTarget._alpha -= 10;
    } else if (alpha == false && myTarget._alpha<=100) {
    myTarget._alpha += 10;
    myButton.onRollOver = function() {
    _root.myFader(clip, 0);
    myButton.onRollOut = function() {
    _root.myFader(clip, 1);

    Edit*** Oops, didn't see sergwiz reply before I posted. One thing to mention in sergwiz code that often confuses folks, did me for a long while, is the use of a nested conditional......

    t ? (this._alpha<=100 ? this._alpha++ : this._alpha=100) : (this._alpha>0 ? this._alpha-- : this._alpha=0);

    This is just shorthand for an if statement.
