HTC Vive键位获取以及物品的拾取方法

HTC Vive开发者的数量不少，也就意味着HTC Vive的应用也会逐渐增多，当这些开发者进行VR的开发的时候，首先面临的两个问题就是HTC键位的获取和物品的拾取问题，想知道方法的就往下看。

Vive键位获取方法：

//获取抓取键
private Valve.VR.EVRButtonId gripButton = Valve.VR.EVRButtonId.k_EButton_Grip;
//调用官方的API，声明一个自己的变量名，随后进行初始化，就可以获得键位啦
SteamVR_TrackedObject trackedObj;
private SteamVR_Controller.Device device ｛ get ｛ return SteamVR_Controller.Input((int)trackedObj.index); ｝ ｝
 void Start()
    ｛
        trackedObj = GetComponent<SteamVR_TrackedObject>();
    ｝
    void Update()
    ｛
       if(device.GetPressDown(gripButton ))
       ｛
            Debug.Lor("按下抓取键");
       ｝
    ｝

物品的拾取方法：

//获取抓取键
    private Valve.VR.EVRButtonId gripButton = Valve.VR.EVRButtonId.k_EButton_Grip;
    //获取扳机键
    private Valve.VR.EVRButtonId triggerButton = Valve.VR.EVRButtonId.k_EButton_SteamVR_Trigger;
    SteamVR_TrackedObject trackedObj;
    private SteamVR_Controller.Device device ｛ get ｛ return SteamVR_Controller.Input((int)trackedObj.index); ｝ ｝
    //要拾取的物品，我叫它灭火器
    public Transform extingusher;
    //model为手柄，此脚本挂在手柄的父物体上
    Transform model;
    // Use this for initialization
    void Start()
    ｛
        trackedObj = GetComponent<SteamVR_TrackedObject>();
        model = this.transform.GetChild(0);
    ｝
    // Update is called once per frame
    void Update()
    ｛
        if (device.GetPressDown(gripButton) && extingusher != null)
        ｛
            //设置灭火器的父节点
            extingusher.SetParent(model);
            extingusher.GetComponent<Rigidbody>().isKinematic = true;      
        ｝
        if (device.GetPressUp(gripButton) && extingusher != null)
        ｛
            extingusher.SetParent(null);
            extingusher.GetComponent<Rigidbody>().isKinematic = false;
        ｝
    ｝
    private void OnTriggerEnter(Collider other)
    ｛
        extingusher = other.gameObject.transform;
    ｝
    private void OnTriggerExit(Collider other)
    ｛
        extingusher = null;
    ｝
