vue +unity 实现云渲染

github地址：GitHub - Unity-Technologies/UnityRenderStreaming: Streaming server for Unity

目前我拉取的是 1.2.3这一分支，拉取到本地后，即可开始调试

一、启动WEBRTC服务器

用vscode打开WEBAPP这个文件夹，在该目录下执行终端命令

npm run build

npm run start

即可开启服务

同时终端窗口还会给出浏览器地址，打开该地址

二、启动Unity

要用2019版本的Unity报错才少，打开后，Unity告知PointerPhase类报错，换成TouchPhase即可，activetouches换成touches即可，这个时候就可以运行Unity了。运行Unity成功后即可看到Game窗口内容如下

三、发现操作与浏览器交互并不能操作unity端

经过代码查看，发现应该是InputSystem.QueueStateEvent这个方法的问题，这个方法调用后，并没有促发Unity的操作功能，所以此时无奈，只能自己些交互操作了。

-----------------------------------------------------------------------

这个时候也对两边的代码进行了改动，首先WEBAPP中的代码，首先把Mouse改成了MouseMove，同时新增了MouseClick的枚举：


const InputEvent = {
  Keyboard: 0,
  MouseMove: 1,
  MouseWheel: 2,
  Touch: 3,
  ButtonClick: 4,
  MouseClick: 5,
};

把SendMouse改成了SendMouseMove和SendMouseClick方法：


function sendMouseMove(e) {
    const scale = _videoPlayer.videoScale;
    const originX = _videoPlayer.videoOriginX;
    const originY = _videoPlayer.videoOriginY;
    if (x && y) {
      const deltaX = (e.clientX - x) / scale;
      const deltaY = (e.clientY - y) / scale;
      let data = new DataView(new ArrayBuffer(9));
      data.setUint8(0, InputEvent.MouseMove);
      data.setFloat32(1, deltaX, true);
      data.setFloat32(5, deltaY, true);
      _videoPlayer && _videoPlayer.sendMsg(data.buffer);
    }
    x = e.clientX;
    y = e.clientY;
 
  }
 
  function sendMouseClick(e) {
    if (e.type == 'mouseup') {
 
      let data = new DataView(new ArrayBuffer(3));
      data.setUint8(0, InputEvent.MouseClick);
      data.setInt16(1, 0, true);
      _videoPlayer && _videoPlayer.sendMsg(data.buffer);
    }
    if (e.type == 'mousedown') {
      let data = new DataView(new ArrayBuffer(3));
      data.setUint8(0, InputEvent.MouseClick);
      data.setInt16(1, 1, true);
      _videoPlayer && _videoPlayer.sendMsg(data.buffer);
    }
  }

最后再修改调用的代码


playerElement.addEventListener('mousedown', sendMouseClick, false);
  playerElement.addEventListener('mouseup', sendMouseClick, false);
  playerElement.addEventListener('mousemove', sendMouseMove, false);
  playerElement.addEventListener('wheel', sendMouseWheel, false);

此时Web端的调用已经修改完成

这个时候register-event的整个代码如下


const InputEvent = {
  Keyboard: 0,
  MouseMove: 1,
  MouseWheel: 2,
  Touch: 3,
  ButtonClick: 4,
  MouseClick: 5,
};
 
const KeyboardEventType = {
  Up: 0,
  Down: 1
}
 
const PointerPhase = {
  None: 0,
  Began: 1,
  Moved: 2,
  Ended: 3,
  Canceled: 4,
  Stationary: 5

再修改Unity的脚本

首先新建一个EventManger.cs的脚本来管理事件代码如下


using System;
using System.Collections.Generic;
 
namespace EventManager
{
    public delegate void ActionHandler(Message message);
    public class Message
    {
        public float arg1;
        public float arg2;
        public string message;
 
        public Message(int arg1, int arg2, string message)
        {
            this.arg1 = arg1;
            this.arg2 = arg2;
            this.message = message;
        }
        public Message(float arg1, float arg2, string message)
        {
            this.arg1 = arg1;
            this.arg2 = arg2;
            this.message = message;
        }
        public Message() { }
    }
 
public class EventManager
    {
        #region Instance
        private static EventManager instance;
 
        public static EventManager GetInstance()
        {
            if (instance == null)
            {
                instance = new EventManager();
            }
 
            return instance;
        }
 
        private EventManager() { }
        #endregion
 
        private Dictionary<string, ActionHandler> actions = new Dictionary<string, ActionHandler>();
 
        public void AddListener(string actionKey, ActionHandler action)
        {
            ActionHandler handler;
            bool exist = actions.TryGetValue(actionKey, out handler);
 
            if (exist)
            {
                //避免重复添加
                Delegate[] delegates = handler.GetInvocationList();
 
                if (Array.IndexOf(delegates, action) == -1)
                {
                    handler += action;
                    actions[actionKey] = handler;
                }
            }
            else
            {
                actions.Add(actionKey, action);
            }
        }
 
        public void RemoveListener(string actionKey, ActionHandler action)
        {
            ActionHandler handler;
            bool exist = actions.TryGetValue(actionKey, out handler);
 
            if (exist)
            {
                handler -= action;
 
                if (handler == null)
                {
                    actions.Remove(actionKey);
                }
                else
                {
                    actions[actionKey] = handler;
                }
            }
        }
 
        public bool BroadcastMessage(string actionKey, Message message)
        {
            ActionHandler handler;
            bool exist = actions.TryGetValue(actionKey, out handler);
 
            if (exist)
            {
                handler(message);
                return true;
            }
            else
            {
                return false;
            }
        }
    }
}

同步修改传来值类型的枚举值，在RemoteInput.cs里


enum EventType
    {
        Keyboard = 0,
        MouseMove = 1,
        MouseWheel = 2,
        Touch = 3,
        ButtonClick = 4,
        MouseClick = 5,
    }

把ProcessMouseEvent拆成PorcessMouseMove和ProcessMouseClick两个方法


static void ProcessMouseMoveEvent(float x, float y)
        {
            //var position = new Vector2Int(x, y);
            //var delta = position - Mouse.current.position.ReadValue();
            EventManager.EventManager.GetInstance().BroadcastMessage("mousemove", new EventManager.Message(x, y, "mouseclick"));
            //InputSystem.QueueStateEvent(RemoteMouse, new MouseState { position = position, delta = delta, buttons = button });
        }
        static void ProcessMouseClickEvent(int state)
        {
 
            EventManager.EventManager.GetInstance().BroadcastMessage("mouseclick", new EventManager.Message(state, 0,"mouseclick"));
        }

最后再改调用方法，注意这里只改了Move方法和Click方法


 public static void ProcessInput(byte[] bytes)
        {
            switch ((EventType)bytes[0])
            {
                case EventType.Keyboard:
                    var type = (KeyboardEventType)bytes[1];
                    var repeat = bytes[2] == 1;
                    var key = bytes[3];
                    var character = (char)bytes[4];
                    ProcessKeyEvent(type, repeat, key, character);
                    InputSystem.Update();
                    break;
                case EventType.MouseMove:
                    var deltaX = BitConverter.ToSingle(bytes, 1);
                    var deltaY = BitConverter.ToSingle(bytes, 5);
                    //var button = bytes[5];
                    ProcessMouseMoveEvent(deltaX, deltaY);
                    InputSystem.Update();
                    break;
                case EventType.MouseWheel:
                    var scrollX = BitConverter.ToSingle(bytes, 1);
                    var scrollY = BitConverter.ToSingle(bytes, 5);
                    Debug.Log(scrollX);
                    ProcessMouseWheelEvent(scrollX, scrollY);
                    InputSystem.Update();
                    break;
                case EventType.Touch:
                    var length = bytes[1];
                    var index = 2;
                    var touches = new TouchState[length];
                    for (int i = 0; i < length; i++)
                    {
                        var identifier = BitConverter.ToInt32(bytes, index);
                        index += 4;
                        var phase = (TouchPhase)bytes[index];
                        index += 1;
                        var pageX = BitConverter.ToInt16(bytes, index);
                        index += 2;
                        var pageY = BitConverter.ToInt16(bytes, index);
                        index += 2;
                        var force = BitConverter.ToSingle(bytes, index);
                        index += 4;
                        touches[i] = new TouchState
                        {
                            touchId = identifier,
                            phase = phase,
                            position = new Vector2Int(pageX, pageY),
                            pressure = force
                        };
                    }
                    ProcessTouchMoveEvent(touches);
                    InputSystem.Update();
                    if (Touchscreen.current.touches.Count > length)
                    {
                        ChangeEndStateUnusedTouches(touches);
                        InputSystem.Update();
                    }
                    break;
                case EventType.ButtonClick:
                    var elementId = BitConverter.ToInt16(bytes, 1);
                    ProcessButtonClickEvent(elementId);
                    break;
                case EventType.MouseClick:
                    var mouseState = BitConverter.ToInt16(bytes, 1);

                ActionButtonClick(elementId);
            }
        }
    }
}

最后我们再创建一个Player.cs脚本来接收监听事件，同时处理EventManger传来的事件，此处我们只做平移事件，旋转事件需要进一步的修改WEBAPP中的方法。此处Player脚本需要挂在在场景的一个Object下，同时还要把RemoteCamera的SimpleCameraController的对象传给它才能正常使用，代码如下，


using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.InputSystem;
using UnityTemplateProjects;
 
public class Player : MonoBehaviour
{
    // Start is called before the first frame update
    int mouseState = 0;
    public SimpleCameraController cameraController;
    void Start()
    {
 
        EventManager.EventManager.GetInstance().AddListener("mouseclick", (e) =>
        {
             mouseState = (int)e.arg1;
        });
        EventManager.EventManager.GetInstance().AddListener("mousemove", (e) =>
        {
            if (mouseState == 1)
            {
                var x = e.arg1;
                var y = e.arg2;
                Vector3 translation = Vector3.right * x * 0.01f;
                translation += Vector3.back * y * 0.01f;
 
                translation *= Mathf.Pow(2.0f, 3.5f);
 
                print(translation);
                cameraController.m_TargetCameraState.Translate(translation); 
            }
        });
    }
 
}

四、最后成果

目前就只做了平移功能，目的只是为了简单的跑起来看看云渲染的延迟
