Camera shaking and barely moving after adding a clamp to x rotation?

Question

 using UnityEngine;
 using System.Collections;
 
 public class CameraController : MonoBehaviour {
 
     public int Sensitivity;
     private float MouseYSet;
 
     void Start () {
         MouseYSet = Input.mousePosition.y;
     }
 
     void Update () {
         transform.localRotation = Quaternion.Euler (Mathf.Clamp (transform.rotation.x, -90, 90), 0, 0);
 
         if (Input.mousePosition.y > MouseYSet)
         {
             transform.Rotate (new Vector3 (-1, 0, 0) * (Input.mousePosition.y - MouseYSet) * Sensitivity * 10 * Time.deltaTime);
             MouseYSet = Input.mousePosition.y;
         }
         if (Input.mousePosition.y < MouseYSet)
         {
             transform.Rotate (new Vector3 (-1, 0, 0) * (Input.mousePosition.y - MouseYSet) * Sensitivity * 10 * Time.deltaTime);
             MouseYSet = Input.mousePosition.y;
         }
     }
 }

you are better to use Input.GetAxisRaw() Instead.

replace your Update() function with this:

 float y = 0f;
 void Update(){
     y-=Input.GetAxisRaw ("Mouse Y") * Sensitivity * 10 * Time.deltaTime;
     y=Mathf.Clamp (y, -90, 90);
     transform.rotation = Quaternion.Euler(y, 0, 0);
 }

I didn't test the code. but hope it will help

One more question, why do you use the - symbol? Is it because when the mouse is on the right its negative and should be positive? if so, what makes it negative?

Don't use Time.deltaTime with "$$anonymous$$ouse X" or "$$anonymous$$ouse Y" as those are already delta values. $$anonymous$$ultiplying those by deltaTime will makes it frame rate dependent. This is actually mentioned in the documentation, though not explained very clearly.

If the axis is mapped to the mouse, the value is different and will not be in the range of -1...1. Instead it'll be the current mouse delta multiplied by the axis sensitivity. Typically a positive value means the mouse is moving right/down and a negative value means the mouse is moving left/up.

This is frame-rate independent; you do not need to be concerned about varying frame-rates when using this value.
