HTCVIVE---VRTK3.2.1的手柄按鈕方法和功能響應（震動，判斷左右手柄，圓盤上下左右）

引用VRTK。

定義一個變量，用來獲取判斷手柄圓盤按下位置的角度，獲取VRTK_ControllerEvents組件

  private VRTK_ControllerEvents Events;
    public float Angle;//按下和擡起圓盤時獲取按下位置的角度

    private void Awake()
    {
        Events = transform.GetComponent<VRTK_ControllerEvents>();
    }

註冊按鍵事件：

 /// <summary>
    /// 各種按鈕響應事件註冊
    /// </summary>
    private void Start()
    {
        Events.ButtonOneTouchStart += Events_ButtonOneTouchStart;

        Events.ButtonTwoTouchStart += Events_ButtonTwoTouchStart;
        Events.ButtonTwoTouchEnd += Events_ButtonTwoTouchEnd;
        Events.ButtonTwoPressed += Events_ButtonTwoPressed;
        Events.ButtonTwoReleased += Events_ButtonTwoReleased;

        Events.TriggerTouchStart += Events_TriggerTouchStart;
        Events.TriggerTouchEnd += Events_TriggerTouchEnd;
        Events.TriggerHairlineStart += Events_TriggerHairlineStart;
        Events.TriggerHairlineEnd += Events_TriggerHairlineEnd;
        Events.TriggerPressed += Event_TriggerPressed;
        Events.TriggerClicked += Events_TriggerClicked;
        Events.TriggerReleased += Events_TriggerReleased;

        Events.TouchpadTouchStart += Events_TouchpadTouchStart;
        Events.TouchpadTouchEnd += Events_TouchpadTouchEnd;
        Events.TouchpadPressed += Events_TouchpadPressed;
        Events.TouchpadReleased += Events_TouchpadReleased;

        Events.GripTouchStart += Events_GripTouchStart;
        Events.GripTouchEnd += Events_GripTouchEnd;
        Events.GripPressed += Events_GripPressed;
        Events.GripClicked += Events_GripClicked;
        Events.GripReleased += Events_GripReleased;

    }

上面就是對應的手柄按鈕的各種方法，包含觸摸，按下，擡起等，都是執行一次。註釋都很清楚了

在Update裏面實現長按方法如下：

  /// <summary>
    /// 各種按鈕長按監測
    /// </summary>
    private void Update()
    {
        if (Events.buttonTwoPressed)
        {
            Debug.Log("Application---LongPressed");
        }
        if (Events.triggerTouched)
        {
            Debug.Log("Trigger---LongTouched");
        }
        if (Events.triggerHairlinePressed)
        {
            Debug.Log("Trigger---LoneHairlinePressed");
        }
        if (Events.triggerPressed)
        {
            Debug.Log("Trigger---LongPressed");
        }
        if (Events.triggerClicked)
        {
            Debug.Log("Trigger---LongClicked");
        }
        if (Events.touchpadTouched)
        {
            Debug.Log("Touchpad---LongTouch");
        }
        if (Events.touchpadPressed)
        {
            Debug.Log("Touchpad---LongPressed");
        }
        if (Events.gripTouched)
        {
            Debug.Log("Grip---LongTouch");
        }
        if (Events.gripClicked)
        {
            Debug.Log("Grip---LongClicked");
        }


        if ((Angle > 0 && Angle <= 45) || (Angle >= 315 && Angle < 360))
        {
            Debug.Log("Up---LongPress");
        }
        if (Angle > 135 && Angle <= 225)
        {
            Debug.Log("Down---LongPress");
        }
        if (Angle > 225 && Angle < 315)
        {
            Debug.Log("Left---LongPress");
        }
        if (Angle > 45 && Angle <= 135)
        {
            Debug.Log("Right---LongPress");
        }
    }

根據實際情況使用對用的方法
