Like the title says, I'm after some kind of constraint for the camera to prevent the player from seeing beyond the scene and seeing the Skybox. I came across the code to add a Mathf.Clamp, but I can't get it to work.
I'm currently trying to make a 2.5D platformer in which the camera follows the player (ahead), which leads to seeing beyond the scene to the far left and right. I already have an invisible wall in place to prevent the player from falling off, but I would love to also clamp the camera from going any further.

This is the script I have at the moment:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CameraController : MonoBehaviour
    [SerializeField] GameObject player = null;
    [SerializeField] [Range(0.1f, 2f)] float followAhead = 2f;
    [SerializeField] [Range(0.1f, 2f)] float smoothing = 1f;

    //public PlayerController playerController;

    private float minPosition = -9.37f;
    private float maxPosition = 4.68f;
    private Vector3 cameraClamp;

    const float m_minY = 2f;
    Vector3 targetPosition;
    Vector3 cameraOffset;

    void Start()
        cameraOffset = transform.position - player.transform.position;

    void Update()
        targetPosition = (player.transform.position + (player.transform.forward * followAhead)) + cameraOffset;
        //smoothedForward = Vector3.MoveTowards(smoothedForward, playerController.GetTravelDirection(), 0.5f * Time.deltaTime);
        //targetPosition = (player.transform.position + (smoothedForward * followAhead));
        //transform.position = player.transform.position + cameraOffset;
        targetPosition.y = Mathf.Min(targetPosition.y, m_minY);
        transform.position = Vector3.Lerp(transform.position, targetPosition, smoothing * Time.deltaTime);
        cameraClamp.x = Mathf.Clamp(transform.position.x, -9.37f, 4.68f);

when clamping the camera to your bounds you want to make sure to re-assign the position like so

-added these in case you wanted to setup and test in inspector but you can set however needed

 public Vector3 MinCamPosition;
 public Vector3 MaxCamPosition;

void Update()
    transform.position = new Vector3(Mathf.Clamp(transform.position.x, MinCamPosition.x, MaxCamPosition.x),
                Mathf.Clamp(transform.position.y, MinCamPosition.y, MaxCamPosition.y), 
                Mathf.Clamp(transform.position.z, MinCamPosition.z, MaxCamPosition.z)); 
  • \$\begingroup\$ You can use Vector3.Min / Vector3.Max to express this a little more concisely. \$\endgroup\$ – DMGregory Apr 25 at 16:15
