Need help tweaking a script

[BassTech]

Hi,

 

I was wondering if anyone would be kind enough to help me. Basically I am using the following script to create a snow effect:

<br />
//Configure below to change URL path to the snow image<br />
var snowsrc="https://vle.queenmaryshigh.walsall.sch.uk/user/74/118004.png"<br />
// Configure below to change number of snow to render<br />
var no = 5;<br />
<br />
var ns4up = (document.layers) ? 1 : 0; // browser sniffer<br />
var ie4up = (document.all) ? 1 : 0;<br />
<br />
var dx, xp, yp; // coordinate and position variables<br />
var am, stx, sty; // amplitude and step variables<br />
var i, doc_width = 800, doc_height = 600;<br />
<br />
if (ns4up) {<br />
doc_width = self.innerWidth;<br />
doc_height = self.innerHeight;<br />
} else if (ie4up) {<br />
doc_width = document.body.clientWidth;<br />
doc_height = document.body.clientHeight;<br />
}<br />
<br />
dx = new Array();<br />
xp = new Array();<br />
yp = new Array();<br />
am = new Array();<br />
stx = new Array();<br />
sty = new Array();<br />
<br />
for (i = 0; i < no; ++ i) { <br />
dx[i] = 0; // set coordinate variables<br />
xp[i] = Math.random()*(doc_width-50); // set position variables<br />
yp[i] = Math.random()*doc_height;<br />
am[i] = Math.random()*20; // set amplitude variables<br />
stx[i] = 0.02 + Math.random()/10; // set step variables<br />
sty[i] = 0.7 + Math.random(); // set step variables<br />
if (ns4up) { // set layers<br />
if (i == 0) {<br />
document.write("<layer name=\"dot"+ i +"\" left=\"15\" top=\"15\" visibility=\"show\"><a href=\"http://dynamicdrive.com/\"><img src='"+snowsrc+"' border=\"0\">");<br />
} else {<br />
document.write("<layer name=\"dot"+ i +"\" left=\"15\" top=\"15\" visibility=\"show\"><img src='"+snowsrc+"' border=\"0\">");<br />
}<br />
} else if (ie4up) {<br />
if (i == 0) {<br />
document.write("<div id=\"dot"+ i +"\" style=\"POSITION: absolute; Z-INDEX: "+ i +"; VISIBILITY: visible; TOP: 15px; LEFT: 15px;\"><a href=\"http://dynamicdrive.com\"><img src='"+snowsrc+"' border=\"0\">");
} else {
document.write(""+snowsrc+"");
}
}
}

function snowNS() { // Netscape main animation function
for (i = 0; i < no; ++ i) { // iterate for every dot
yp[i] += sty[i];
if (yp[i] > doc_height-50) {
xp[i] = Math.random()*(doc_width-am[i]-30);
yp[i] = 0;
stx[i] = 0.02 + Math.random()/10;
sty[i] = 0.7 + Math.random();
doc_width = self.innerWidth;
doc_height = self.innerHeight;
}
dx[i] += stx[i];
document.layers["dot"+i].top = yp[i];
document.layers["dot"+i].left = xp[i] + am[i]*Math.sin(dx[i]);
}
setTimeout("snowNS()", 10);
}

function snowIE() { // IE main animation function
for (i = 0; i < no; ++ i) { // iterate for every dot
yp[i] += sty[i];
if (yp[i] > doc_height-50) {
xp[i] = Math.random()*(doc_width-am[i]-30);
yp[i] = 0;
stx[i] = 0.02 + Math.random()/10;
sty[i] = 0.7 + Math.random();
doc_width = document.body.clientWidth;
doc_height = document.body.clientHeight;
}
dx[i] += stx[i];
document.all["dot"+i].style.pixelTop = yp[i];
document.all["dot"+i].style.pixelLeft = xp[i] + am[i]*Math.sin(dx[i]);
}
setTimeout("snowIE()", 10);
}

if (ns4up) {
snowNS();
} else if (ie4up) {
snowIE();
}

 

The problem is it only works properly in IE7, is it possible to change it to work with IE8, FireFox and Google Chrome?

 

Thanks to anyone who helps

This is the one iv used in the past, works with everything even safari and firefox!

plus can be changed to fairy lights (sorry!! i mean puff lanterns) very easily

 

 

 

Enjoy!

Hi, thanks for the script. I tried this but the website I'm using it on has a java menu and every time you put your mouse on the menu it causes the snow to freeze (no pun intended ) and then it doesn’t continue to snow unless you refresh the page. Is there any way to get around this? It happens on all browsers

 

Thanks
