I could tell you right now!

The carpet (or conveyor belt) isn’t actually rolling, but the little dashes move along to make it look like it’s rolling. That’s accomplished with a simple motion tween with a guide so that it hugs the belt’s surface. Add a couple of rolling wheels and the effect is accomplished!

And ofcourse, the thing rolls on command using the “tellTarget” function.
