我决定休假学习Unity3D中Vive的开发。 Google搜索了几个示例，并开始尝试，但由于某种原因，它不起作用。 在开始更详细地了解后，发现Valve最近推出了Unity3D的插件更新-一个新的，重做的版本。 它出现了几个基本的创新，使旧教程不再适用。 我决定写一个新的
我们将需要Unity> = 5.4.0和新的SteamVR插件插件 （ GitHub ）
在插件本身中，有三个有用的pdf文件可供您熟悉
\资产\ SteamVR \ SteamVR Unity插件.pdf
\ Assets \ SteamVR \ SteamVR Unity插件-输入系统.pdf
\资产\ SteamVR \ InteractionSystem \ InteractionSystem.pdf
还有两个例子：
\资产\ SteamVR \简单Sample.unity
\资产\ SteamVR \ InteractionSystem \样本\ Interactions_Example.unity
该插件支持模拟模式-如果未打开头盔，它将打开
好吧，现在一步一步来；
使用SteamVR插件创建一个新的3D模板项目
我们同意设置
现在的关键是您需要配置管理。 选择菜单项Window \ SteamVR Imput
Unity将询问缺少的actions.json并提供复制示例文件（位于\ Assets \ SteamVR \ Input \ ExampleJSON中）-我建议您同意。
json文件显示，该插件不仅为Vive设计，还为Oculus和Windows MR以及新的关节控制器设计。 与此相关的重大更改。
在打开的窗口中，只需点击“保存并生成”
现在，您需要将播放器（来自\ Assets \ SteamVR \ InteractionSystem \ Core \ Prefabs的播放器）添加到场景中并删除主摄像机
为了使模拟模式起作用-必须在播放器的属性中将其启用
将\ Assets \ SteamVR \ InteractionSystem \ Core \ Icons文件夹复制到\ Assets并将其重命名为Gizmos也很有用
您可以单击播放-但是模拟中只有假手无法使用，您需要从此处复制脚本并将其挂在Player-> NoSteamVRFallbackObjects-> FallbackHand上
假手稿代码using System.Collections.Generic; using UnityEngine; using Valve.VR; public class VrSimulatorHandFixer156 : SteamVR_Behaviour_Pose { Valve.VR.InteractionSystem.Hand _hand; protected override void Start() { base.Start(); _hand = this.gameObject.GetComponent<Valve.VR.InteractionSystem.Hand>(); _hand.handType = SteamVR_Input_Sources.RightHand; GameObject broHand = GameObject.Instantiate(_hand.gameObject); Destroy(broHand.GetComponent<VrSimulatorHandFixer156>()); broHand.SetActive(false); _hand.otherHand = broHand.GetComponent<Valve.VR.InteractionSystem.Hand>(); _hand.otherHand.handType = SteamVR_Input_Sources.LeftHand; var spoofMouse = new SpoofMouseAction(); _hand.grabGripAction = spoofMouse; spoofMouse.InitializeDictionariesExposed(_hand.handType); this.poseAction = new Poser_SteamVR_Action_Pose(); } protected override void OnEnable() { } protected override void Update() { _hand.grabGripAction.UpdateValue(SteamVR_Input_Sources.RightHand); } protected override void OnDisable() { } protected override void CheckDeviceIndex() { }
在VR模式下，控制器已打开-它们将可见
我们添加了VR，但我们甚至无法四处走动。 该插件具有远距传输的实现
要启用它，您需要从\ Assets \ SteamVR \ InteractionSystem \ Teleport \ Prefabs添加到Teleporting场景
并从那里安排TeleportPoint
您也可以使用T键模仿传送。
您可以创建一个隐形运输表面-创建一个平面，并将TeleportArea.cs脚本从\ Assets \ SteamVR \ InteractionSystem \ Teleport \ Script挂在其上
让我们尝试与对象进行交互-创建一个多维数据集，并将Interactable.cs脚本从\ Assets \ SteamVR \ InteractionSystem \ Core \ Script上挂起
现在突出显示了，但没有任何反应
我们需要注册交互-我们将为Cube创建一个新脚本
交互代码 using System.Collections; using System.Collections.Generic; using UnityEngine; using Valve.VR.InteractionSystem; public class NewBehaviourScript : MonoBehaviour { private Hand.AttachmentFlags attachmentFlags = Hand.defaultAttachmentFlags & (~Hand.AttachmentFlags.SnapOnAttach) & (~Hand.AttachmentFlags.DetachOthers) & (~Hand.AttachmentFlags.VelocityMovement); private Interactable interactable; // Use this for initialization void Start () { interactable = this.GetComponent<Interactable>(); } private void HandHoverUpdate(Hand hand) { GrabTypes startingGrabType = hand.GetGrabStarting(); bool isGrabEnding = hand.IsGrabEnding(this.gameObject); if (startingGrabType != GrabTypes.None) { // Call this to continue receiving HandHoverUpdate messages, // and prevent the hand from hovering over anything else hand.HoverLock(interactable); // Attach this object to the hand hand.AttachObject(gameObject, startingGrabType, attachmentFlags); } else if (isGrabEnding) { // Detach this object from the hand hand.DetachObject(gameObject); // Call this to undo HoverLock hand.HoverUnlock(interactable); } } }
可以在插件的示例中找到有关交互的更多详细信息，尤其是在\ Assets \ SteamVR \ InteractionSystem \ Samples \ Scripts \ InteractableExample.cs中
然后，我们将尝试执行示例中未包含的内容-添加新操作
打开Player.cs脚本并添加字段
[SteamVR_DefaultAction("PlayerMove", "default")] public SteamVR_Action_Vector2 a_move; [SteamVR_DefaultAction("PlayerRotate", "default")] public SteamVR_Action_Vector2 a_rotate; [SteamVR_DefaultAction("MenuClick", "default")] public SteamVR_Action_Boolean a_menu;
有效的返回类型可以在\资产\ SteamVR \输入中找到
和Update方法：
private void Update() { bool st = a_menu.GetStateDown(SteamVR_Input_Sources.Any); if (st) { this.transform.position = new Vector3(0, 0, 0); } else { Camera camera = this.GetComponentInChildren<Camera>(); Quaternion cr = Quaternion.Euler(0, 0, 0); if (camera != null) { Vector2 r = a_rotate.GetAxis(SteamVR_Input_Sources.RightHand); Quaternion qp = this.transform.rotation; qp.eulerAngles += new Vector3(0, rx, 0); this.transform.rotation = qp; cr = camera.transform.rotation; } Vector2 m = a_move.GetAxis(SteamVR_Input_Sources.LeftHand); m = Quaternion.Euler(0, 0, -cr.eulerAngles.y) * m; this.transform.position += new Vector3(mx / 10, 0, my / 10); } }

运行Window \ SteamVR Imput，在默认集中创建我们的操作并保存，现在选择“打开绑定UI”（SteamVR必须正在运行并且至少一个控制器已打开）
控制器绑定选项卡在浏览器中打开-您需要在其中配置我们的动作与控制器的连接：我们将PlayerMove挂在左侧的TRACKPAD上（不要忘记关闭镜像模式），将PlayerRotate挂在右侧的TRACKPAD上，并挂起MenuClick在菜单键上
关闭控制器绑定并保存更改。
在播放器的属性中，我们将新动作关联
启动播放
专案
结论
应注意几点。 SteamVR Imput中的某些动作会使Unity长时间思考，原则上，您可以在代码中自行进行这些更改，而不是使用Controller Binding，您可以直接编辑json文件，但是存在很大的错误风险，可能很难发现错误。
为了更深入地研究插件-详细研究示例非常有用，当然-阅读文档。
