Last night I had decided the setting to be in a tight space station environment. However got stuck in trying to create a zero gravity first person movement.

In Unity I made a physics box with gravity off and have a camera attach to it. Next I try many different combination of how to move and rotate it. However controlling the movement is frustrating. It is also disorientating when the camera can view in one direction and the body move in another direction.

In the end I give up and import UFPS a first person controller. I didn't use it initially as I wasn't able to figure it out. Took me up to 5am in the morning to figure out how to use it. However still not really the zero gravity movement. I wonder why I wasn't able to before. I guess it is working under the time pressure. Was so tired I slept for 12 hrs after that. I guess I relax a while more and continue tonight.
