Using event methods with attachMovie?

[InvaderPiotr]

As an exercise, I'm trying to build a menu system like the one at http://www.teknision.com.

So, let's assume that I'm working on just one 'slice' of the navigation, a series of movie clips with previous and next arrows to navigate between them, with easing done in AS using deltas.

Now, I'm using a loop to build the MCs horizontally and a couple of buttons for scrolling back and forth, and that works fine, but I can't figure out how to do is fade each MC in sequentially - have them fade in one after the other (or delay it the way Teknision's done it - as they come on, they appear one after the other with a pause in between each one).

I thought I could try an alpha fade on the MC as it's attached inside the loop like so:


for (i=0; i<=_root.clipamount; i++){

//make clips
this.attachMovie ("daclip", "daclip"+i, i+1);
this["daclip"+i]._x = this["daclip"+i]._width * i + (i*5);
this["daclip"+i]._y = 80;

//get width of clip
this["daclip"+i].clipwidth = this["daclip"+i]._width;

//trying to fade the clip... what am I doing wrong?
this["daclip"+i].onLoad = function() {
this._alpha = 1;
}

this["daclip"+i].onEnterFrame = function () {
this._alpha += 1;
}

}


...but that doesn't work. If I put a fade into the blank MC that I use to build the menu it obviously fades all of them in at the same time.

What's the flaw in my logic?

Many thanks,

Piotr

what does it do? The are problems with the onLoad event. You might want to change

this["daclip"+i].onLoad = function() {
this._alpha = 1;
}

to

this["daclip"+i]._alpha = 1;

Would somehow implementing the setInterval() function work?

[InvaderPiotr]

It seems to me that that's what I should be trying to do... using timers in loops, as I naively first thought of doing, doesn't work.

I found an example of someone covering the screen in MCs with each one being delayed slightly here (http://www.actionscript.org/forums/showthread.php3?s=&threadid=22878) (posted towards the bottom by Freddycodes), but my AS skills are still limited enough for me to not fully understand what's happening there and adapt it to making a single row of MCs that attach to another, blank MC whose position I can then ease back and forth with a set of buttons. Hopefully I can figure it out... ah, perseverance.

setInterval should work fine

i=0;
function makeClip(){
//make clip
this.attachMovie ("daclip", "daclip"+i, i+1);
this["daclip"+i]._x = this["daclip"+i]._width * i + (i*5);
this["daclip"+i]._y = 80;

//get width of clip
this["daclip"+i].clipwidth = this["daclip"+i]._width;

//trying to fade the clip... what am I doing wrong?
this["daclip"+i].onLoad = function() {
this._alpha = 1;
}

this["daclip"+i].onEnterFrame = function () {
this._alpha += 1;
}
i++;
if(i>_root.clipamount){
clearInterval(makeMenu);
}
}
menuMaker=setInterval(makeClip,1000);

something like that anyway

Okay, here's a demo of what I think you're trying to accomplish. I didn't try using ActionScript to increase the alpha level of each movieclip; instead I used a tweening affect in each movie.

Hope this helps!
