Movement based on hud for GearVR

Sorry for the very basic/noobish question but I’ve spent the day searching and haven’t figured out how to implement this yet. I’m trying to work with the GearVR and Want to create make my movement function based on the crosshair. IE, camera is on a spingarm 3rd person from character and I want to look in a direction, perform a raycast, and then initiate the movement to that direction until the location is reached or a new location is given.

Thanks for any help and I really like the community here.
