Looping from _parent on alpha fadeout

1

Hi,

I’m trying to loop a function as soon as the alpha from my text fades out completely, but I’ve read somewhere that alpha may not reach exactly 0 and don’t know how to handle this problem.

this is the function i have in the main timeline:

function attachClips():Void{
    attachMovie("independencia_mc","independencia",this.getNextHighestDepth(),{_x:200, _y:350});
}


attachClips();

and this is in an attached clip that calls the fadeout function onSoundComplete:

fadeOutInd = function():Void{
    trace(ind._alpha);
    trace(ind);
    new Tween(ind, "_alpha", None.easeNone, ind._alpha, 0, 2, true);
    if(ind._alpha == 0){
    ind.removeTextField();
    _parent.attachClips();
    }
}

but it doesn’t work and I don’t remember how to trace the actual alpha of the text

any ideas?
