Hi,
I *think* this does what you're trying to do, which would be to fade
the alpha of an image in and out again over 24h. I don't have AS2 so I
can't test, but when you do, you can set minutesPerDay to however long
you may wish to sit there and watch the magic happen. If it happens,
that is, because as I said it's untested.
Please, reconsider putting it into an enterFrame handler. It's really
enough to run it every couple of minutes.
Also, no, unfortunately I have no idea why Flash is acting up for you.
The operator use appears to be correct.
var sunrise : Number = 6; // hour of day when sun begins to rise
var maxAlpha : Number = 100;
var minutesPerDay : Number = 24 * 60;
var time : Date = new Date();
var minuteOfDay : Number = time.getHours() * 60 + time.getMinutes();
var deltaMinutes : Number = (minuteOfDay - sunrise * 60 +
minutesPerDay) % minutesPerDay;
var cycleElapsed : Number = deltaMinutes / minutesPerDay; // [0...1[
var alpha : Number = Math.abs( 0.5 - cycleElapsed ) * 2 * maxAlpha;
BKGND.BKGND_Grad._alpha = alpha;
HTH,
Mark
