Ed, one for you?
This should be, and probably is, very simple, but I can't get it to work. I want to modify the script easing to a bounce effect, as seen here:

http://www.gmarwaha.com/jquery/jcarousellite/#demo

He has the code on the page, but it's the 1.1 version, and I'm using the 1.3.
Nomenclature is altered, as are the calls to correct previous bugs... I've tried every which way but obviously not learned enough to properly script it.

My current scroll method can be seen here:

http://www.johnmossdesigns.com/clientTest/LCC/rentals/rentalsByName.html

Here are the current settings:

(function($) {
$.fn.jCarouselLite = function(o) {
o = $.extend({
btnPrev: null,
btnNext: null,
btnGo: null,
mouseWheel: false,
auto: null,
speed: 100,
easing: false,
vertical: false,
circular: true,
visible: 7,
start: 0,
scroll: 3,
beforeStart: null,
afterEnd: null
}, o || {});


Here is the easing 1.3 js:

// t: current time, b: begInnIng value, c: change In value, d: duration
jQuery.easing['jswing'] = jQuery.easing['swing'];
jQuery.extend( jQuery.easing,
{
def: 'easeOutQuad',
swing: function (x, t, b, c, d) {
//alert(jQuery.easing.default);
return jQuery.easing[jQuery.easing.def](x, t, b, c, d);
},
easeInQuad: function (x, t, b, c, d) {
return c*(t/=d)*t + b;
},
easeOutQuad: function (x, t, b, c, d) {

Gracias Senor!

Hey John, did you try setting easing: false, to easing: easeOutBounce, or any other easing function?

johnMoss

Yes. That in theory should work; I suspect the problem lie in the initial class (function?) calls. Point being the command is not being recognized; i.e, doesn't show up in blue in DW when typed in, and sure enough browser freezes when trying to load.

Right now it only takes true or false commands

In script.js there are all the functions to fire the plugins to their associated selectors.
At the top of script.js there are selectors for jCarouselLite. #gallery2 is the one you need and as you can see there you can define the type of easing.

$("#gallery2").jCarouselLite({
btnNext: ".next2",
btnPrev: ".prev2",
visible: 3,
speed: 600,
easing: 'easeOutCirc'
});

As you can see it's now set to easeOutCirc and if you want to change it set it to easeOutBounce for example

Ah... It did not occur to me to even look at that file... I didn't pay good enough attention to the fact that speed changes for example went unheeded in the carousel file... That did it, thanx :)

Certainly a lot more fun to play with when you find the on switch... Funny, the bounce is neat when used with thumbnails, and obnoxious with larger images. I went with a soft landing instead...
