UnityWebCore插件使用学习

 

UnityWebCore 插件是实现将一个网页的内容呈现在一个Mesh Render中,并且允许鼠标键盘与网页内容交互.

使用第一步:

配置好UnityWebCore的环境:

如下图,将dll文件添加到插件文件夹Plugins下(没有就新建一个):

第二步:

在场景中添加的一个panel与灯光panel是用来显示网页内容的容器,我这就把它命名为browserView.

 

第三步:

将官方给的脚本复制过来

编写脚本 UnityWebView.cs:

using UnityEngine;
using System.Collections;
using System.Runtime.InteropServices;
 
public class UnityWebView : MonoBehaviour
{
   public int width, height;
   private GUITexture gui;
       privateTexture2D m_    texture;   
       publicint m_TextureID;
   private Color[] m_pixels = null;
   private GCHandle m_pixelsHandler;   
       publicbool m_bForceOpenGL = true;
   public bool m_bInitialized = false;
       privateUnityWebViewEvents browserEventHandler;
      
       privateUnityWebCore.BeginNavigationDelFunc               beginNavigationDelFunc;
       privateUnityWebCore.BeginLoadingDelFunc                    beginLoadingDelFunc;
       privateUnityWebCore.FinishLoadingDelFunc           finishLoadingDelFunc;
       privateUnityWebCore.ReceiveTitleDelFunc                     receiveTitleDelFunc;
       privateUnityWebCore.ChangeTooltipDelFunc           changeTooltipDelFunc;
       privateUnityWebCore.ChangeTargetURLDelFunc      changeTargetURLDelFunc;
       privateUnityWebCore.ChangeCursorDelFunc            changeCursorDelFunc;
       privateUnityWebCore.JSCallbackDelFunc                showControlWindowFunc;   
       publicstring url ="http://www.baidu.com";
   // Use this for initialization
   void Start()
    {
       browserEventHandler = GetComponent<UnityWebViewEvents>();
       Init(800, 600);      //这里初始化网页窗口的大小（类似于浏览器的大小）它会因为                                     //meshRender的大小而进行拉伸变化
              LoadURL(url);      //调用这个函数开始加载网页。
    }
 
       voidOnGUI () {
             
              if(Event.current.keyCode == KeyCode.Return){
                     this.enabled= false;
                     //ithappens right after the component is disabled
              }
             
       }
      
       voidOnApplicationQuit()
    {
        UnityWebCore.DestroyView(m_TextureID);
    }
 
   public void Init(int width, int height)
    {
       this.width = width;
       this.height = height;
       m_texture = new Texture2D(width, height, TextureFormat.ARGB32, false);
              m_TextureID= m_texture.GetNativeTextureID();

           }
       }
       catch (System.Exception e)
       {
           Debug.Log(e);
       }      
    }
}

第四步：

再把写好的脚本UnityWebView.cs添加到browserView上去：

 

点击运行就能看到效果了：
