I have continually kept on trying to change POV

I really need it so when I press the sprint key my POV changes like in every game, but every tutorial is old and doesn’t work. I would really appreciate some help. TY

You could do something like this:

public class Player : MonoBehaviour {

    public float sprintFOV = 80f;
    private float normalFOV;
    
    void Start()
    {
         normalFOV = Camera.main.fieldOfView;//set normal field of view
    }

    void Update()
    {
        if(sprinting)//you have to set sprinting bool yourself
        {
              Camera.main.fieldOfView = sprintFOV;//set FOV to sprinting
        }
        else
        {
              Camera.main.fieldOfView = normalFOV;//set FOV to normal
        }
   }
}

or animate it using unity’s animation system.
