XF1 [TUT] Snow Effect

1.0, 1.1, 1.2, 1.3, 1.4, 1.5
Guide to make your forum with falling Snow flakes

Step 01 : Create a custom .js file
Open Notepad++ and paste the codes below and save as .js file (Eg. Snow.js)

Code:
// CREDITS:

// Distributed by http://www.hypergurl.com
// Permission given to use the script provided that this notice remains as is.

// Set the number of snowflakes (more than 30 - 40 not recommended)
var snowmax=3;

// Set the colors for the snow. Add as many colors as you like
var snowcolor=new Array("#FFFFFF");

// Set the fonts, that create the snowflakes. Add as many fonts as you like
var snowtype=new Array("vrinda","verdana", "trebuchet ms", "times new roman", "lucinda sans","impact");

// Set the letter that creates your snowflake (recommended:*)
var snowletter="*";

// Set the speed of sinking (recommended values range from 0.3 to 2)
var sinkspeed=0.3
// Set the maximal-size of your snowflaxes
var snowmaxsize=48;

// Set the minimal-size of your snowflaxes
var snowminsize=24;

// Set the snowing-zone
// Set 1 for all-over-snowing, set 2 for left-side-snowing
// Set 3 for center-snowing, set 4 for right-side-snowing
var snowingzone=1;

// duration is time in milliseconds of effect.
var start, duration=10000000;

Step 02 : Copy it to public_html/js/xenforo or in any directory

Step 03 : Go to template page_container_js_body and include the function below

Code:
<xen:require js="js/xenforo/snow.js" />
Change the directory in the above function if you copied in somewhere else.
