Problem with an endless runner

How do I...?
1

Hello everyone! (The game is an endless runner)
I have a problem with that light blue sprite, it practically moves with the ground but I only want the ground to move.
How could I do?

If you want only the ground to move, the easiest way is to put your ground as a tiled sprite and have a conditionless action adding something like 10 * TimeDelta() to the X offset of the tiled sprite.

Thanks for the help!@arthuro555
