X-mas Snow Effect

[awyett]

[awyett]

Ask on the dynamicscript site where the code comes from.

[awyett]

okay, thanks

Xarcell, thanks this is very cool. Just asking, can it be made to only appear on the home page and not while folks are playing the arcade. Doesnt affect the game, it just locks up the arcade for few.

I found another snow script in Dynamic Drive which doesnt use any images. It works best with a dark background.


This is what i did. I used the Global Headers and Footers mod found HERE, and I inserted the following code into the headers section.

Code Select Expand

<script type="text/javascript" src="snow.js">

/***********************************************
* Snow Effect without images-by Kurt Grigg at http://www.btinternet.com/~kurt.grigg/javascript
* Script featured & available at Dynamic Drive at http://www.dynamicdrive.com/
* Please keep this notice intact
***********************************************/

</script>



Then

I saved the following as snow.js
(You can download the file from here).

//Snow - http://www.btinternet.com/~kurt.grigg/javascript

if  ((document.getElementById) &&
window.addEventListener || window.attachEvent){

(function(){

//Configure here.

var num = 30;   //Number of flakes
var timer = 30; //setTimeout speed. Varies on different comps
var enableinNS6 = 1 //Enable script in NS6/Mozilla? Snow animation could be slow in those browsers. (1=yes, 0=no).

//End.

var y = [];
var x = [];
var fall = [];
var theFlakes = [];
var sfs = [];
var step = [];
var currStep = [];
var h,w,r;
var d = document;
var pix = "px";
var domWw = (typeof window.innerWidth == "number");
var domSy = (typeof window.pageYOffset == "number");
var idx = d.getElementsByTagName('div').length;

if (d.documentElement.style &&
typeof d.documentElement.style.MozOpacity == "string")
num = 12;

for (i = 0; i < num; i++){
sfs[i] = Math.round(1 + Math.random() * 1);

document.write('<div id="flake'+(idx+i)+'" style="position:absolute;top:0px;left:0px;width:'
+sfs[i]+'px;height:'+sfs[i]+'px;background-color:#ffffff;font-size:'+sfs[i]+'px"><\/div>');

currStep[i] = 0;
fall[i] = (sfs[i] == 1)?
Math.round(2 + Math.random() * 2): Math.round(3 + Math.random() * 2);
step[i] = (sfs[i] == 1)?
0.05 + Math.random() * 0.1 : 0.05 + Math.random() * 0.05 ;
}


if (domWw) r = window;
else{
  if (d.documentElement &&
  typeof d.documentElement.clientWidth == "number" &&
  d.documentElement.clientWidth != 0)
  r = d.documentElement;
else{

}


function winsize(){
var oh,sy,ow,sx,rh,rw;
if (domWw){
  if (d.documentElement && d.defaultView &&
  typeof d.defaultView.scrollMaxY == "number"){
  oh = d.documentElement.offsetHeight;
  sy = d.defaultView.scrollMaxY;
  ow = d.documentElement.offsetWidth;
  sx = d.defaultView.scrollMaxX;
  rh = oh-sy;
  rw = ow-sx;
}
else{
  rh = r.innerHeight;
  rw = r.innerWidth;
}
h = rh - 2; 
w = rw - 2;
}
else{
h = r.clientHeight - 2;
w = r.clientWidth - 2;
}
}


function scrl(yx){
var y,x;
if (domSy){
y = r.pageYOffset;
x = r.pageXOffset;
}
else{
y = r.scrollTop;
x = r.scrollLeft;
}
return (yx == 0)?y:x;
}


function snow(){
var dy,dx;

for (i = 0; i < num; i++){
dy = fall[i];
dx = fall[i] * Math.cos(currStep[i]);

y[i]+=dy;
x[i]+=dx;

if (x[i] >= w || y[i] >= h){
  y[i] = -10;
  x[i] = Math.round(Math.random() * w);
  fall[i] = (sfs[i] == 1)?
  Math.round(2 + Math.random() * 2): Math.round(3 + Math.random() * 2);
  step[i] = (sfs[i] == 1)?
  0.05 + Math.random() * 0.1 : 0.05 + Math.random() * 0.05 ;
}

theFlakes[i].top = y[i] + scrl(0) + pix;
theFlakes[i].left = x[i] + scrl(1) + pix;

currStep[i]+=step[i];
}
setTimeout(snow,timer);
}


function init(){
winsize();
for (i = 0; i < num; i++){
theFlakes[i] = document.getElementById("flake"+(idx+i)).style;
y[i] = Math.round(Math.random()*h);
x[i] = Math.round(Math.random()*w);
}
snow();
}


if (window.addEventListener){
window.addEventListener("resize",winsize,false);
window.addEventListener("load",init,false);
} 
else if (window.attachEvent){
window.attachEvent("onresize",winsize);
window.attachEvent("onload",init);
}

})();
}//End.

I then uploaded the snow.js file into the root folder of my forum.

Here is the Dynamic Drive Demo.
Here is the result in my site.

I just pasted the first code into the headers using the Global Headers and Footers mod, and it worked just fine.

radel, can you please elaborate.

@william, edited my post above.....

Thanks for your help.

It shouldn't do that, but if it does, then lessen the number of flakes in the snow.js file. The default is 30, try 15 instead.
