Camera moves through terrain

Hi. I am having some issues getting my camera script to stop going through the terrain. This is the original issue I had - https://prnt.sc/rsvjao

I made a fix, but it only partially fixed the issue, as now if the player runs down a hill (a place with a descending y coordinate) with the camera along the floor, the camera passes through the terrain that is above the camera. https://prnt.sc/rsvisb
Here is my script

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Movement : MonoBehaviour {
6.  
7.     public Transform playerCamera, character, centrePoint;
8.     public float rotationSpeed, zoomSpeed, playerSpeed, minZoom, maxZoom, increaseMouseY, defaultZoom, sprintSpeed, yCameraOffset;
9.  
10.     private float mouseX, mouseY, moveFB, moveLR;
11.     private float zoom;
12.     // move front back, move left right
13.  
14.     public Animator anim;
15.  
16.     void Start() {
17.         zoom = defaultZoom; // base zoom  value
18.     }
19.  
20.     void Update() {
21.  
22.         zoom += Input.GetAxis("Mouse ScrollWheel") * zoomSpeed;
23.  
24.         if (zoom > minZoom) {
25.             zoom = minZoom;
26.         }
27.  
28.         if (zoom < maxZoom) {
29.             zoom = maxZoom;
30.         }
31.  
32.         playerCamera.transform.localPosition = new Vector3(0, yCameraOffset, zoom);
33.         // this handles the actual zoom
34.  
35.         if (Input.GetKeyDown(KeyCode.LeftShift) && Input.GetKey(KeyCode.W)) {
36.             anim.SetBool("running", true);
37.         }
38.  
39.         if (Input.GetKeyUp(KeyCode.LeftShift)) {
40.             anim.SetBool("running", false);
41.         }
42.  
43.         float realSpeed = (Input.GetKey(KeyCode.LeftShift) && Input.GetKey(KeyCode.W)) ? sprintSpeed : playerSpeed;
44.  
45.  
46.         if (Input.GetMouseButton(1)) {
47.             mouseX -= Input.GetAxis("Mouse Y") * rotationSpeed; // dont question this inversion, it works... this works for me at the moment but probably some F*** up in settings
48.             mouseY += Input.GetAxis("Mouse X") * rotationSpeed;
49.         }
50.  
51.  
52.  
53.         mouseX = Mathf.Clamp(mouseX, Terrain.activeTerrain.GetPosition().x - 40, 25);
54.         // THIS IS THE LINE WHERE I TRIED TO FIX IT ^^^
55.  
56.         playerCamera.LookAt(centrePoint);
57.         centrePoint.localRotation = Quaternion.Euler(mouseX, mouseY, -1);
58.  
59.         moveLR = Input.GetAxis("Horizontal") * realSpeed;
60.         moveFB = Input.GetAxis("Vertical") * realSpeed;
61.  
62.         if (moveFB != 0 || moveLR != 0) {
63.             anim.SetBool("walking", true);
64.         } else {
65.             anim.SetBool("walking", false);
66.         }
67.  
68.         Vector3 movement = new Vector3(moveLR, 0, moveFB);
69.         movement = character.rotation * movement;
70.  
71.         character.GetComponent<CharacterController>().Move(movement * Time.deltaTime);
72.         centrePoint.position = new Vector3(character.position.x, character.position.y + increaseMouseY, character.position.z);
73.  
74.         if (Input.GetAxis("Vertical") != 0) {
75.             Quaternion turnAngle = Quaternion.Euler(0, centrePoint.eulerAngles.y, 0);
76.             character.rotation = Quaternion.Slerp(character.rotation, turnAngle, rotationSpeed * Time.deltaTime);
77.         }
78.     }
79.  
80. }
81.
