Need script to randomly fade mcs?

I need a script to select a random order of six mcs named mc1 to mc6 (fade each down one at a time one after another) once all six have each faded up from 0 alpha to 100 I want it to randomly fade those six mcs down from 100 alpha to '0' alpha again, all one mc at a time so this loops around and goes through again.

So it selects a randoom order and fades one mc in at a time and once all six faded in all six fade out one at a time.

How can this be done I can get the fade down up thing going but how to do the random thing??

What can I do to make a gate?

I want a bit of code so that first time it's called it makes something true and the next time it calles through that gate it makes it false.

Kind of like how a two click button code works click once doesnt work and click second time and it does and loops, so on.

I have a trigger that I know when all the clips are down or up but need that alternating gate.

Then I will put:

if (fadeturn=true){
//do fade up
}
if(fadeturn=false){
//do fade down
}

I wrote this so far can anyone help with a better way i should have done this:

There is just six mcs on stage with a pic in each and named from 'mc6' though to 'mc11'

chechMc = setInterval(nextMC,500);
fadeturn=true;
myRandomMcs = new Array(6, 7, 8, 9, 10, 11);
function nextMc() {
nextMcToFade = myRandomMcs.splice(random(myRandomMcs.length), 1);
trace(["mc_"+nextMcToFade]);
fadeClips();
if (nextMcToFade.length == isNaN(0)) {
trace("Empty array");
//this is where I need the alternating tricker each time to set fadeturn true or false
myRandomMcs.push(6, 7, 8, 9, 10, 11);
nextMcToFade = myRandomMcs.splice(random(myRandomMcs.length), 1);
}
}
MovieClip.prototype.fadeClips = function() {
this.onEnterFrame = function() {
if (fadeturn=true) {
//do fade up
this["mc_"+nextMcToFade]._alpha += 3;
}
if (fadeturn=false) {
this["mc_"+nextMcToFade]._alpha -= 3;
}
};
};

PHP Code:

---

chechMc = setInterval (nextMC, 500);
fadeturn = false;
myRandomMcs = new Array (6, 7, 8, 9, 10, 11);
function nextMc ()
{
    nextMcToFade = myRandomMcs.splice (random (myRandomMcs.length), 1);
    trace (["mc_" + nextMcToFade]);
    var myMc:String = "mc_" + nextMcToFade;
    fadeClips (myMc);
    if (nextMcToFade.length == isNaN (0))
    {
        trace ("Empty array");
        //this is where I need the alternating tricker each time to set fadeturn true or false
        myRandomMcs.push (6, 7, 8, 9, 10, 11);
        nextMcToFade = myRandomMcs.splice (random (myRandomMcs.length), 1);
    }
}
function fadeClips (myMc)
{
    var mc:MovieClip = eval (myMc);
    this.onEnterFrame = function ()
    {
        if (fadeturn == true)
        {
            //do fade up
            mc._alpha += 3;
        }
        if (fadeturn == false)
        {
            mc._alpha -= 3;
            if (mc._alpha <= 0)
            {
                delete this.onEnterFrame;
                nextMc ();
            }
        }
    };
}
nextMc ();

Ok you've posted yours and i was just about to post where i was up to. This almost working. Is eval depreciated?

But know it needs to be condensed down but cant work out how??

Code:

---

myRandomMcsUp = new Array(6, 7, 8, 9, 10, 11);
MovieClip.prototype.nextMc = function() {
        nextMcToFade = myRandomMcsUp.splice(random(myRandomMcsUp.length), 1);
        fadeClips();
        if (nextMcToFade.length == isNaN(0)) {
                trace("Finished fading up will now begin fade down");
                myRandomMcsUp.push(6, 7, 8, 9, 10, 11);
                nextMcToFade = myRandomMcsUp.splice(random(myRandomMcsUp.length), 1);
                nextMcDown();
        }
        trace(["mc_"+nextMcToFade]);
};
MovieClip.prototype.fadeClips = function() {
        this.onEnterFrame = function() {
                this["mc_"+nextMcToFade]._alpha += 5;
                if (this["mc_"+nextMcToFade]._alpha>=100) {
                       
                        nextMc();
                }
        };
};
MovieClip.prototype.nextMcDown = function() {
        nextMcToFade = myRandomMcsUp.splice(random(myRandomMcsUp.length), 1);
        fadeClipsDown();
        if (nextMcToFade.length == isNaN(0)) {
                myRandomMcsUp.push(6, 7, 8, 9, 10, 11);
                nextMcToFade = myRandomMcsUp.splice(random(myRandomMcsUp.length), 1);
                nextMc();
                trace("Finished fading down will now begin fade down");
        }
        trace(["mc_"+nextMcToFade]);
};
MovieClip.prototype.fadeClipsDown = function() {
        this.onEnterFrame = function() {
                this["mc_"+nextMcToFade]._alpha -= 5;
                if (this["mc_"+nextMcToFade]._alpha<=0) {
                        nextMcDown();
                }
        };
};

I don't know your lower script but you can also change the two lines to this:

var myMc:MovieClip = this["mc_" + nextMcToFade];

var mc:MovieClip = myMc;

if you don't like eval.

That first script I did was just to check with setinterval. But the fades we're not working right.

Second one does fade right but just having a problem with it doing 5 mcs then 8 then 4 then 7. Should be six faded up six faded down just in random order.

And need just one script I think maybee with a function. Not the four differnt functions the way I have it now!

So just looking to tidy up the hack we got now and get a decent working code.

Flashscipt can you tell me how to use your script. When i have put it in the first frame and with the six mcs on stage with pics in them, the trace goes mad and traces every frame.

It's tracing right but should be finishing fading each clip before next.

see attachment.

Thanks for that flashscript.biz I appreaciate that!
