3D Sidescroller Swimming

I am trying to get a physics volume based water movement in a sidescroller game. My input is setup as in the pic. Basically if I press up I need to be able to swim up and if I press down, swim down. Can anyone please explain how to do this?

Answering for those who come after because I figured it out. Screenshot below. basically leave MoveRight Input alone and add a moveUP with a branch for isSwimming.

Hi, I am facing this exact same problem, I can’t see your screenshot as the link is invalid, can you please send another one?
