Endless Runner Block Spawn simulation Problem

Hi everyone,

I’m following along on the endless runner tut on Youtube. I’m at the point where he simulates the rocks spawning. It doesn’t work for me. I’m using version 4.13.0.

Here are the shots:

Also if anyone has any idea on how I can move my character sideways more smoothly?

Thanks.
