    PlayerControls inputActions;//声明 InputSystem的脚本对象
    public new Rigidbody rigidbody;
    Vector2 movementInput;//存储 WASD输入的值

    [Header("Stats")]
    [SerializeField]
    float movementSpeed = 5;


    // Start is called before the first frame update
    void Start()
    {
        rigidbody = GetComponent<Rigidbody>();
    }

    // Update is called once per frame
    void Update()
    {
        Vector3 vector3 = new Vector3(movementInput.x * movementSpeed, 0, movementInput.y * movementSpeed);
        rigidbody.velocity = vector3;//给刚体 这个方向的速度
    }


    public void OnEnable()
    {
        //获取设备上的输入
        if (inputActions==null)
        {
            inputActions = new PlayerControls();
            //绑定输入的值
            inputActions.PlayerMovement.MovementAction.performed += outputActions => movementInput = outputActions.ReadValue<Vector2>();
        }

        inputActions.Enable();//启用
    }
