"can you make a wasd movement for unity and when i press shift the walkspeed will change and the camera pov will be more back"

Here's a script that allows WASD movement in Unity, changes walk speed when pressing Shift, and adjusts the camera field of view when Shift is pressed.

```csharp
using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    public float walkSpeed = 3f;
    public float runSpeed = 6f;
    public float rotationSpeed = 100f;
    public Camera playerCamera;
    public float normalFOV = 60f;
    public float runningFOV = 80f;

private CharacterController controller;
    private float currentSpeed;
    private Vector3 moveDirection;

void Start()
    {
        controller = GetComponent<CharacterController>();
        currentSpeed = walkSpeed;
    }

void Update()
    {
        float horizontal = Input.GetAxis("Horizontal");
        float vertical = Input.GetAxis("Vertical");

moveDirection = new Vector3(horizontal, 0, vertical);
        moveDirection.Normalize();

if (Input.GetKey(KeyCode.LeftShift))
        {
            currentSpeed = runSpeed;
            playerCamera.fieldOfView = Mathf.Lerp(playerCamera.fieldOfView, runningFOV, Time.deltaTime * 5f);
        }
        else
        {
            currentSpeed = walkSpeed;
            playerCamera.fieldOfView = Mathf.Lerp(playerCamera.fieldOfView, normalFOV, Time.deltaTime * 5f);
        }

controller.SimpleMove(moveDirection * currentSpeed);
    }
}
```

Attach this script to your player GameObject and assign the player's camera to the `playerCamera` field in the Inspector. Adjust the walkSpeed, runSpeed, normalFOV, and runningFOV values as needed.
