How to take z value on a position to move a camera? (cannot modify the return value of 'Transfo-CodePudding

I have an object that moves forward backward left and right and i want the camera to move up and down not left and right i tried using the z value but i have an error (im not the best at coding) https://i.stack.imgur.com/riVoA.png if you have a answer please help

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class followplayer : MonoBehaviour
{
    public Transform playerchar;
    public Vector3 cameraOffset;
    // Start is called before the first frame update
    void Start()
    {
        cameraOffset = transform.position - playerchar.transform.position;
    }


    // Update is called once per frame
    void Update()
    {
        Vector3 newPosition = playerchar.transform.position   cameraOffset;
        transform.position.z = newPosition.z;
    }
}

CodePudding user response：

You cannot change transform.position this way. That's the correct way to do so:

transform.position = new Vector3(transform.position.x, transform.position.y, newPosition.z);

CodePudding user response：

Use the Quickway:

var tPos = transform.position;
tPos.z = newPosition.z;
transform.position = tPos;
