Why do I only have left/right mouse movement

Questions & Answers

Keep in mind that only been looking into coding this past week and I’m not sure on how to make everything work for a simple first PersonController/Camera

I’ve been reading on how to create the code and I am the closest I’ve been on making it work using this.

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

[RequireComponent(typeof(Rigidbody))]
public class FPController : MonoBehaviour {

    public float speed = 5f;

    private Transform cam;
    private Rigidbody rb;
    private Vector3 velocity = Vector3.zero;
    private float mouseSensitivity = 250f;
    private float verticalLookRotation;
    
    //use this for initialization
    void Start ()
    {
        rb = GetComponent<Rigidbody>();
        cam = Camera.main.transform;
    }

    //update is called once per frame
    void Update ()
    {
        float xMov = Input.GetAxisRaw("Horizontal");
        float yMov = Input.GetAxisRaw("Vertical");
        float zMov = Input.GetAxisRaw("Jump");

        Vector3 movHor = transform.right * xMov; // (1, 0, 0,)
        Vector3 movVer = transform.forward * yMov; // (0, 0, 1,)
        Vector3 movUp = transform.up * zMov; // (0, 1, 0,)
        velocity = (movHor + movVer + movUp).normalized * speed;

        transform.Rotate(Vector3.up * Input.GetAxis("Mouse X") * Time.deltaTime * mouseSensitivity);
        verticalLookRotation += Input.GetAxis("Mouse Y") * Time.deltaTime * mouseSensitivity;
        verticalLookRotation = Mathf.Clamp(verticalLookRotation,-60, 60);
        cam.localEulerAngles = Vector3.left * verticalLookRotation;
    }

     private void FixedUpdate()
    {
        if (velocity != Vector3.zero)
        {
            rb.MovePosition(rb.position + velocity * Time.fixedDeltaTime);
        }
    }
}

After following The video on Coding First Person Controller

After following along and Checking over the code multiple times I see this in my console

If anyone that knows a bit more about this than I do could explain what I did wrong and how to fix it would make me very grateful!
Thank you in advance!

The error is null reference

  • meaning camera.main.transform.(missing reference here);

Just some examples to set reference - Example;

    cam = camera.main.transform.position;
    cam = camera.main.transform.up;
    cam = camera.main.transform.left;
    cam = camera.main.transform.translate;
    cam = camera.main.transform.lookat;
    cam = camera.main.transform.right;
    cam = camera.main.transform.eulerangles;
    cam = camera.main.transform.rotation;
    cam = camera.main.transform.forward;
