erro no script de movimentação na Unity

eu estou usando: Character Controller

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

public class player : MonoBehaviour
{
    private CharacterController controller;
    private Animator anim;

    public float speed;
    public float gravity;

    private vector3 rot;
    private vector3 moveDirection;

    // Start is called before the first frame update
    void Start()
    {
        controller = GetComponent<CharacterController>();
        anim = GetComponent<Animator>();
    }

    // Update is called once per frame
    void Update()
    {
        move()
    }

    void move()
    {
        if(controller.isGroundded)
        {
           if(Input.GetKey(KeyCode.w))
           {
            moveDirection = vector3.forward * speed;
           }
           if(Input.GetKeyUp(KeyCode.w)
        }

        moveDirection.y -= gravity * time.deltaTime;
        
        controller.move(moveDirection * time.deltaTime);

    }
}
