环境:
- VS2015
- Unity 5.3.6f1 (64-bit)
目的:
Unity官方提供的UnityWebPlayer控件在嵌入Winform时要求读取的.unity3d文件路径(Src)必须是绝对路径,如果移动代码到另一台电脑,需要重新修改src。于是考虑使用winform用户控件来进行封装,以实现读取存放在工程文件夹下的.unity3d文件的效果。

过程
首先新建windows用户窗体库。
然后在空白控件上添加UnityWebPlayer,这一步是为了添加Interop.UnityWebPlayerAXLib.dll、AxInterop.UnityWebPlayerAXLib.dll两个引用。
当引用列表里出现这两个引用时,把刚才添加的UnityWebPlayer控件删除。
然后修改控件的.cs文件,代码如下
//U3DPlayer.csusing System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;namespace UnityPlayer
{public partial class U3Dplayer: UserControl{#region 自定义事件//委托public delegate void ExternalCallHandler(object sender, AxUnityWebPlayerAXLib._DUnityWebPlayerAXEvents_OnExternalCallEvent e);/// <summary>/// 接收Unity调用宿主函数的消息/// </summary>[Browsable(true), Description("接收Unity调用宿主(如WinForm)函数的消息")]public event ExternalCallHandler UnityCall;//方法public void OnUnityCall(object sender, AxUnityWebPlayerAXLib._DUnityWebPlayerAXEvents_OnExternalCallEvent e){if (UnityCall != null){UnityCall(sender, e);}}#endregion#region 内部变量private AxUnityWebPlayerAXLib.AxUnityWebPlayer _axUnityWebPlayer = null;#endregion/// <summary>/// 用户控件函数/// </summary>public U3Dplayer(){InitializeComponent();string src = Application.StartupPath + "\\unity.unity3d";//在这里设置路径_axUnityWebPlayer = CreateUnity(this, src);OnExternalCallCheck();this.Controls.Add(_axUnityWebPlayer);//在原控件上添加UnityWebPlayer控件}/// <summary>/// 建立一个新的unity控件并设置一些属性/// </summary>/// <param name="form"></param>/// <param name="src"></param>/// <returns></returns>public static AxUnityWebPlayerAXLib.AxUnityWebPlayer CreateUnity(Control form, string src){var unity = new AxUnityWebPlayerAXLib.AxUnityWebPlayer();((System.ComponentModel.ISupportInitialize)(unity)).BeginInit();form.Controls.Add(unity);((System.ComponentModel.ISupportInitialize)(unity)).EndInit();unity.src = src;AxHost.State state = unity.OcxState;//最关键的是OcxState,必须使用AxUnityWebPlayer才能依据Src动态产生。unity.Dispose();unity = new AxUnityWebPlayerAXLib.AxUnityWebPlayer();((System.ComponentModel.ISupportInitialize)(unity)).BeginInit();form.SuspendLayout();unity.Dock = DockStyle.Fill;//unity.Size = new System.Drawing.Size(720, 450);unity.Name = "Unity";unity.OcxState = state;unity.TabIndex = 0;//unity.Location = new System.Drawing.Point(0, 0);((System.ComponentModel.ISupportInitialize)(unity)).EndInit();form.ResumeLayout(false);return unity;}private void OnExternalCallCheck(){if (_axUnityWebPlayer == null){throw new Exception("_axUnityWebPlayer init fail");}else{_axUnityWebPlayer.OnExternalCall += _axUnityWebPlayer_OnExternalCall;}}void _axUnityWebPlayer_OnExternalCall(object sender, AxUnityWebPlayerAXLib._DUnityWebPlayerAXEvents_OnExternalCallEvent e){if (e.value.StartsWith("LOAD_COMPLETE")){if (!_axUnityWebPlayer.Visible){_axUnityWebPlayer.Width = this.Width;_axUnityWebPlayer.Height = this.Height;_axUnityWebPlayer.Show();}}OnUnityCall(sender, e);}#region SendMessage/// <summary>/// 发送消息给Unity/// </summary>/// <param name="unityObjName">Unity中的对象名称</param>/// <param name="unityScriptyMethod">Unity脚本中的方法</param>/// <param name="val">传送的值.仅限于int、float、string</param>public void SendMessage(string unityObjName, string unityScriptyMethod, object val){if (_axUnityWebPlayer == null){return;}_axUnityWebPlayer.SendMessage(unityObjName, unityScriptyMethod, val);}#endregion}
}
然后选择生成动态链接库。
在Winform工程中选择“工具”–“选择工具箱项”–导入,即可使用
