Unity & Hydra

I've been spinning my wheels trying to figure out how to tweak scripts for my OR unity project so I can use the hydra's joystick to control movement (w,a,s,d)- is there anyone who could point me in the right direction? It seems to be a simple problem but I'm very new to scripting and this has me stumped!

Would there a hydra equivalent for its joystick to getkeydown or getaxis? If this isn't an appropriate place to ask this just let me know.
