Hi, welcome to the forums.


You just need to use the camelCase property names for your tweens (backgroundPosition instead of background-position):

TweenLite.to($$, time,
	{backgroundPosition: cur_xPos + ' ' + y + 'px', ease: opts.easing}
You should always use camelCase for all of the CSS properties you are tweening.
