unknown jquery code model

[gongpex]

Hello everyone,

I found a piece of cake jquery code such this :

	$.Animation( this, {
			x: x,
			y: y
		}, { 
			duration: speed
		}).progress( function( e ) {
			this.css( "background-position", e.tweens[0].now + "px " + e.tweens[1].now + "px" );
		});

When I looked for $.Animation and progress reference on google I didn't find it.

Q : Could y'all help me to find this reference?

Many Thanks

If you have the rest of the source code from that page you should be able to see which libraries are being included. 

It is either a jQuery plugin or not jQuery at all.

Alright I will give you the full of code, tell me where is the method of JQuery according code on below :

(function( $ ) {
	$.fn.animateBgPosition = function( x, y, speed ) {
		var pos = this.css( "background-position" ).split( " " );
		
		
		this.x = parseInt( pos[0], 10 ) || 0;
		this.y = parseInt( pos[1], 10 ) || 0;
	
		$.Animation( this, {
			x: x,
			y: y
		}, { 
			duration: speed
		}).progress( function( e ) {
			this.css( "background-position", e.tweens[0].now + "px " + e.tweens[1].now + "px" );

Hello thanks for reply,

How about $.Animation ?

I didn't find it on google,

could u give me documentation link please?

Thanks

I imagine it is part of jQuery framework, as the link said there is not much documentation on these terms specifically, as these are part of jQuerys animation() function where the user would add the required information, then the tweens(), $Animation would be used in framework background itself..
