Continuous Scrolling background

[celli]

I am trying to achieve a continuous scrolling background, and I have set up a .png that is twice as long as my container so that it can repeat and start and stop in the exact same position.

 

I am using the background position property, which works, but I see the "repeat:-1" still has a slight pause every time it repeats, so this is very noticeable if you want to create a scrolling background that appears continuous, like for a scrolling star background.

 

I altered the code at the codepen to this with linear easing, but every combination of easing and repeating, even with negative delays still do not produce a smooth continuous scrolling background. Is there something else I need to do to make it appear to continuously scroll ?

TweenMax.to(".test", 1, {backgroundPosition:"-80px 0px", repeat:-1, easeIn : Linear});

Can you provide a Codepen that exhibits this pause so we can see what you are seeing? I modified that GreenSock pen and couldn't see any pause.

TweenMax.to(".test", 4, {backgroundPosition:"-80px 0px", repeat:-1, ease:Linear.easeNone});

easeIn is not a recognised easing property of GSAP, and the Linear class on it's own doesn't create an ease. You need to define eases using the syntax ease:Class.type e.g.

ease:Linear.easeNone
ease:Power2.easeOut
ease:Power3.easeIn
etc

It was my easing !! Thanks that worked very well. Here's a sample of what I was trying to accomplish, very simple!
