What can I do to make a camera actor BP never possibly move left and only right?

I have something similar to that, a boolean called “facing right” for the players and it works out fairly good but still a few small quarks.

If you could only see how convoluted my camera actor blue prints get sometimes with attach walls and things hehe. It is what I use to hold the players in.

Let me ask you this, I have noticed sometimes I have to set floats with a Do Once node to get some looks Im after VS setting them with something fast firing like an Event Tick which does nothing. What is your opinion on this?
