Question Restrict player x axis rotation

Hi i am trying to restrict the players x axis and cannot seem to figure out a solution with my code, clamping does not work at all. Any assistance would be appreciated.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using Unity.VisualScripting;
4. using UnityEditor.Experimental.GraphView;
5. using UnityEngine;
6.  
7. public class CharController : MonoBehaviour
8. {
9.     public float speed = 3.0F;
10.  
11.     public float rotationSpeed = 4.0f;
12.     private float Pitch = 0.0f;
13.     private float Yaw = 0.0f;
14.  
15.     // Start is called before the first frame update
16.     void Start()
17.     {
18.         CharacterController controller = GetComponent<CharacterController>();
19.  
20.         // Disable Cursor Visibility and lock it to centre of screen
21.         Cursor.visible = false;
22.         Cursor.lockState = CursorLockMode.Locked;
23.     }
24.  
25.     // Update is called once per frame
26.     void Update()
27.     {
28.         // Get the Character controller
29.         CharacterController controller = GetComponent<CharacterController>();
30.  
31.         // Move forward / backward
32.         Vector3 forward = transform.TransformDirection(Vector3.forward);
33.         float curSpeed = speed * Input.GetAxis("Vertical");
34.         controller.SimpleMove(forward * curSpeed);
35.  
36.         // Set Pitch and Yaw with mouse
37.         Yaw = Input.GetAxis("Mouse X") * rotationSpeed;
38.         Pitch = Input.GetAxis("Mouse Y") - Input.GetAxis("Mouse Y") * rotationSpeed;
39.  
40.         Pitch = Mathf.Clamp(Pitch, -80, 80);
41.  
42.         // Apply Pitch and Yaw to player
43.         transform.eulerAngles += new Vector3(Pitch, Yaw, 0);
44.  
45.     }
46. }

 

Notes on clamping camera rotation and NOT using .eulerAngles because of gimbal lock:
