I've been asking this question for months without an answer.
How can I create a script that (when a player walks) simulates the visual movement you would have in real life when walking.
A good example would be the ones in FPS's except less jerky.
Let's just say.. that you already know animation and walking styles.. But if you're talking about Camera Manipulation then I would go to Camera Manipulation
Then I would learn about CFrames
And welding (if needed to like weld the CameraPart to the player head or something. So it gives that motion of when the player is walking with animation.)
Sorry if I couldn't provide an actual script, as this is hard for me to do-so myself.
