How to change background image on scrolling

[yx13]

Hi,
Does anyone knows how to change the background image when scrolling?
From state1 -> state2 -> state3

Are you just trying to flip between images, like a sprite sheet? Animate the position, like panning across the image? Pretty much anything is possible...I'm just not sure what you're looking for. But you could animate the backgroundPosition and wire that up to a ScrollTrigger. Maybe give that a shot and if you get stuck, provide a minimal demo (like a CodePen) so we can take a peek at the issue in context.
