I have a ball that bounces when it reaches the edges of viewport, I have this working with modifiers.   However, I'm trying to do this infinitely which I have tried by calling the tween function again but visually there's a slight pause when it restarts. How can I fix this? An approach I thought of was to make my translate values longer and adjust duration but this wouldn't frequently touch the edge of the viewports.
