How do I move a sprite across the screen repeatedly forever?

Hi - I'm trying to do something I think should be simple but I can't work out. I'm trying to have a black bar move smoothly across the screen from left to right then, when it reaches the other side, start again from the left (not move leftwards back across the screen), repeating infinitely.

I guess it could be created, move across and be destroyed then this process repeat. Or it could hit the far edge and teleport back then continue moving smoothly right. The problem is my understanding of how to make this happen more than once.

Thank you

There's a Wrap behaviour you can assign to the object and you can tie it to the viewport or the layout. It'll come back around the opposite side of the screen.

Sine behavior is what you need.

With Movement at Horizontal

and Wave at Sawtooth

Then you can play with Magnitude to fit it with your screen and with period for the time you want to arrive.

Very helpful, thank you
