I’m following Brackeys FPS movement (FIRST PERSON MOVEMENT in Unity - FPS Controller - YouTube) timestamp linked and I can’t seem to drag the Character to the script.
Script:

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

public class MouseLook : MonoBehaviour
{

    public float mouseSenstivity = 100f;
    public Transform playerBody;

    void Update()
    {
        float mouseX = Input.GetAxis("Mouse X") *mouseSenstivity * Time.deltaTime;
        float mouseY = Input.GetAxis("Mouse Y") *mouseSenstivity * Time.deltaTime;
      
        playerBody.Rotate(Vector3.up * mouseX);
    }

}

Either Drag the “First Person Player” object in the inspector to that area on the script, it will autofill the transform, or click on the target icon on that area on the script and select it in the list
