* 实现目标：

When the handle touches the box,扣动扳机键,拿起盒子（Cube）.松开扳机键,放下盒子

a、Get handle reference

b、手柄与Box的碰撞检测

c、获取按钮事件

d、抓取：Boxas a handletransform的子物体,失去rigibody相关属性

e、松开：Box的parent为空,regain itselfrigibody相关属性

* 实现步骤

1、导入SteamVR SDK

2、Delete the originalCamera,拖入[CameraRig]、Create a new box、地面

Adjustable head size：[CameraRig]——SteamVR_PlayArea——Size

3、Get handle reference

The script hangs on the right hand,即Controller (right)

    private SteamVR_TrackedObject trackedObject;
    private SteamVR_Controller.Device device;
	// Use this for initialization
	void Start () {
        trackedObject = GetComponent<SteamVR_TrackedObject>();
        device = SteamVR_Controller.Input((int)trackedObject.index);
	}

4、手柄与Box的碰撞检测

给两个Controller添加Sphere Collider,Colliderand scaled down slightly to fit,勾选Is Trigger,给盒子添加Rigidbody

    private void OnTriggerEnter(Collider other){ }
    private void OnTriggerExit(Collider other){ }

5、获取按钮事件

	void Update () {
        if (device.GetPressDown(SteamVR_Controller.ButtonMask.Touchpad)){ }
        if (device.GetPressUp(SteamVR_Controller.ButtonMask.Trigger)){ }
    }

6、手柄震动

device.TriggerHapticPulse(700);

7、Implementation of grab and let go events

改变cubeThe parent object of the object,改变cubeWhether to use gravity and dynamicsIs Kinematic

Is Kinematic：是否开启动力学,If enabled, the game is no longer affected by the physics engine,只受transform影响

全代码展示：

using UnityEngine;
public class MyController: MonoBehaviour {
    SteamVR_TrackedObject trackedObject;
    SteamVR_Controller.Device device;
    //Get what you collided withbox
    GameObject interactBox;
    // Use this for initialization
    void Start()
    {
        trackedObject = GetComponent<SteamVR_TrackedObject>();
        device = SteamVR_Controller.Input((int)trackedObject.index);
    }
    void Update()
    {
        //按下Trigger键
        if (device.GetPressDown(SteamVR_Controller.ButtonMask.Trigger))
        {
            if (interactBox != null)
            {
                interactBox.transform.parent = transform;
                interactBox.GetComponent<Rigidbody>().useGravity = false;
                interactBox.GetComponent<Rigidbody>().isKinematic = true;
            }
        }
        //松开Trigger键
        if (device.GetPressUp(SteamVR_Controller.ButtonMask.Trigger))
        {
            if (interactBox != null)
            {
                interactBox.transform.parent = transform.parent.parent;
                interactBox.GetComponent<Rigidbody>().useGravity = true;
                interactBox.GetComponent<Rigidbody>().isKinematic = false;
                interactBox = null;
            }
        }
    }
    void OnTriggerEnter(Collider other)
    {
        interactBox = other.transform.gameObject;
    }
    void OnTriggerExit(Collider other)
    {
        interactBox = null;
    }
    void OnTriggerStay(Collider other)
    {
        if (device != null)
        {
            //触发震动
            device.TriggerHapticPulse(700);
        }
    }
}
