Unity3D可以C#指令碼進行開，使用vstu2013.msi外掛，可以實現在VS2013中的除錯。在開發完成後，由於專案需要，需要將Unity3D嵌入到WinForm中。WinForm中的UnityWebPlayer Control可以載入Unity3D。先看效果圖。
一、為了能夠動態設定axUnityWebPlayer的Src，我使用使用者控制元件來封裝。看下面的程式碼。

((System.ComponentModel.ISupportInitialize)(unity)).EndInit();
this.ResumeLayout(false);
_axUnityWebPlayer = unity;
if (_axUnityWebPlayer == null)
{
throw new Exception("_axUnityWebPlayer init fail");
}
else
{
_axUnityWebPlayer.OnExternalCall += _axUnityWebPlayer_OnExternalCall;
_axUnityWebPlayer.Hide();
ShowProgressBar();
}
}

const int WM_RBUTTONDOWN = 0x204;
const int WM_RBUTTONUP = 0x205;
const int WM_RBUTTONDBLCLK = 0x206;
// 遮蔽右鍵訊息區域。
System.Drawing.Rectangle my_Area = new System.Drawing.Rectangle(_axUnityWebPlayer.Location, _axUnityWebPlayer.Size);
if (my_Area.Contains(this.PointToClient(Control.MousePosition)))
{
switch (m.Msg)
{
case WM_RBUTTONDOWN:
return true;
case WM_RBUTTONUP:
return true;
case WM_RBUTTONDBLCLK:
return true;
default:
return false;
}
}
return false;
}
}
}
注：程式碼中還實現了其他的功能，如下
1.增加InitUnity方法，方便外層控制元件呼叫。這裡最關鍵的是OcxState，必須使用AxUnityWebPlayer才能依據Src動態產生。
2.動態增加進度條。
3.在實始化後對_axUnityWebPlayer進行隱藏，同時啟動進度條，並繫結Unity的回撥事件OnExternalCall。在OnExternalCall事件中，監聽Unity發來的LOAD_COMPLETE值，然後判斷是否顯示_axUnityWebPlayer.
4.為了能讓外層也收到Unity發來的訊息，使用委託二次實現了OnExternalCall，也就是OnUnityCall方法。
5.SendMessage的實現，第一個引數為Unity中的物件名稱，第二個引數為Unity指令碼中的方法，第三個引數是傳送的值(僅限於int、string,其他的會失敗或者異常)。
6.繼承IMessageFilter介面，捕獲訊息，然後過濾_axUnityWebPlayer區域內產生的滑鼠右鍵訊息，同時增加DisableMouseRight屬性來控制。
7.一定要將專案調成x86的模式，否則會報“沒有註冊類XXX”的資訊。
8.axUnityWebPlayer控制元件需要在工具箱中新增，如下圖。
二、窗體介面的程式碼
using System;using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace UnityHost
{
public partial class FormHost : Form
{
public FormHost()
{
InitializeComponent();
}
private void buttonSendToUnity_Click(object sender, EventArgs e)
{
String info = textBoxSendMessage.Text;
if (String.IsNullOrWhiteSpace(info))
{
MessageBox.Show("請輸入內容");
return;
}
u3DPlayer1.SendMessage("Main Camera", "CallUnity", info);
}
private void FormHost_Load(object sender, EventArgs e)
{
String src = Application.StartupPath + "\\UnityWeb\\UnityWeb.unity3d";
u3DPlayer1.InitUnity(src);
}
private void u3DPlayer1_UnityCall(object sender, AxUnityWebPlayerAXLib._DUnityWebPlayerAXEvents_OnExternalCallEvent e)
{
this.Text = "收到Unity的訊息:" + e.value;
}
}
}
三、Unity3D的C#指令碼
using UnityEngine;
using System.Collections;using System;
public class Main : MonoBehaviour
{
private string _messageReceive = string.Empty;
private bool _isButtonClick = false;
private int _notifyTimeAfterLoadComplete = 3;
// Use this for initialization
void Start()
{
}
// Update is called once per frame
void Update()
{
}
void OnGUI()
{
if (GUI.Button(new Rect(100, 10, 80, 20), "測試"))
{
_isButtonClick = !_isButtonClick;
}
GUI.Label(new Rect(50, 30, 150, 30), _messageReceive);
if (_isButtonClick)
{
Application.ExternalCall("ToWinform", Guid.NewGuid().ToString());
_isButtonClick = false;
}
if (_notifyTimeAfterLoadComplete>0)
{
Application.ExternalCall("LOAD_COMPLETE", "");
_notifyTimeAfterLoadComplete--;
}
}
void CallUnity(object val)
{
_messageReceive = string.Format("{0}", val);
}
}
注:
1.CallUnity是響應WinForm發來訊息的函式。
2.Application.ExternalCall是向WinForm發出訊息，第一引數是函式的名稱，第二個之後的引數是函式的引數。
四、Unity3D要在WebPlayer模式下編譯
