modifica a Script

[KID.A]

Ho questo script che esegue un'animazione x fiocchi di neve che scendono...ma per visualizzarli che salgono (ad es. dei palloncini anziché i fiocchi di neve, come immagine collegata), cosa devo cambiare tra i parametri ?

<script language="JavaScript1.2">

GRAZIE e ciao!

ps:
Perché non riescono a "coesistere" 2 scripts (entrambi inseriti tra le tags BODY ?
ossia funziona solo l'effetto "snow" (che vorrei invertire con animazione da basso verso alto) e viene bl[]occato l'altro script che dà un effetto "glow" al testo, questo:

<SPAN id=theText style="WIDTH: 100%">
<H3 align=center><FONT face="Arial,Comic Sans MS" color=#000000 size=+5>Archy's 
Place </FONT><FONT color=#666666>
<SCRIPT>
<!--
//you can modify the following
 
var from = 5;                    //the animation start value
var to = 11;           //the animation end value
var delay = 55;      //the animation speed
var glowColor = "lime";          //the color of the glow
 
//no editing below here
 
var i = to;
var j = 0;
textPulseDown();
function textPulseUp()
{
if (!document.all)
return
if (i < to)
{
theText.style.filter = "Glow(Color=" + glowColor + ", Strength=" + i + ")";
i++;
theTimeout = setTimeout('textPulseUp()',delay);
return 0;
}
if (i = to)
{
theTimeout = setTimeout('textPulseDown()',delay);
return 0;
}
}
 
 
function textPulseDown()
{
if (!document.all)
return
if (i > from)
{
theText.style.filter = "Glow(Color=" + glowColor + ", Strength=" + i + ")";
i--;
theTimeout = setTimeout('textPulseDown()',delay);
return 0;
}
if (i = from)
{
theTimeout = setTimeout('textPulseUp()',delay);
return 0;
}
}
//-->
</SCRIPT>

il motivo x cui i due script vanno in conflitto è che hai una var i in entrambi, cambia quella nel secondo in k e potranno coesistere

perfetto!
grazie, nn me ne ero accorto...
