I am working on a project where there is a conveyor belt. On this belt items move from left to right. I am using TimeineMax with multiple tweenMax items. Once an item is off the screen the item is changed and I call tweenMax.restart() - works great. What I am trying to do is reverse the belt using reverse() so the items go from right to left. I can do this without issue but I am having trouble figuring out how to restart the tween once it gets to the beginning of the tween. I need the item to restart the reverse process going from the end to the beginning. Any ideas on how to accomplish this?
