A little tutorial fps recreate the unity and maybe still can not figure out how to do that when you go (w, a, s, d) so disturbing to weapon and not just blindly go ahead but the camera is a little swayed. And I do not know how to do it when moving the camera so that the gun a little bit swayed, and the same for shooting that shook a little.
???
I am sorry I really didn’t understand what problem you are running into. However, if you have tried the FPS tutorial here and are still running into problems, please post the specifics of it. Else, I would highly recommend looking into the tutorial for starting FPS game.
