It’s a bit hard to see some of the nodes, but I think the setup makes sense for the most part. I think the easiest way to do this might be to set a bool each time the player turns right or left. True is left, false is right, then check that when you spawn the next tile and branch to one direction or the other depending on the value of that bool. However, that depends on when/where the function to add a tile is called. I can’t tell (or remember from the tutorial) when that happens so you need to do it before the player is on the spot where the new tile should be. Hope that makes sense and helps at least a little.
