How do install a plugin?

Question

So I got the htmlTexturePlugin from the unity wiki here http://wiki.unity3d.com/index.php?title=HtmlTexturePlugin

and I'm not sure how to get it to work. I dropped the bundle I downloaded into unity and I got it to install something called htmlTexture. Then I placed the sample code they have on the wiki into a script and placed that script on a plane. But I got back a bunch of errors. One error was" 'm_Texture' does not exist in the current context". Here is the code I used. using UnityEngine; using System.Collections; public class htmlTexture : MonoBehaviour { public int width =512; public int height = 512; void Start() { m_Texture = new Texture2D (width, height, TextureFormat.ARGB32, false); m_Texture.Apply(); htmlTexture_start(m_Texture.GetInstanceID(), width, height, "http://google.com"); // put the texture on something transform.renderer.sharedMaterial.mainTexture = m_Texture; } void Update() { htmlTexture_update( m_Texture.GetInstanceID() ); } void OnApplicationQuit() { htmlTexture_stop(); } }

You need to declare m_Texture's type.

I hate unofficial tutorials for exactly this reason. Why would someone provide that example code in such a flawed state? O_o

You need this line in your class to make m_Texture a class variable:

 Texture2D m_Texture;

I'm still having problems getting this code to work. Is this how you setup the code?

 using UnityEngine;
 using System.Collections;
 using System;
 using System.Runtime.InteropServices;
 using System.Text;
  
 public class DisplayWebpage : MonoBehaviour {
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_start( int textID, int width, int height, string url );
     //    creates the offscreen window and webview
     //    url: initial URL to display, use null for none
     //    width, height: currently must be a power of 2 (i.e. 128, 256, 512, 1024) due to my using GL_TEXTURE2D
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_stop();
     // releases all windows and webview; use on quit
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_update ( int texID );
     // makes bitmap of the webview and loads it into openGL with the given texture ID
  
     //
     // browser functions
     //
     // as you'd expect, handles any URL, HTML and CSS that webkit can
     //
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_setURL( int texID, string url);
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_getURL( int texID, StringBuilder url, int stringCapacity);
     // to get the current URL, you need to pass in a StringBuilder and its capacity (to
     // avoid buffer overflow errors)
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_goBack( int texID );
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_goForward( int texID );
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_sendJavascript( int texID, string js);
     // sends a string to the webview's javascript interpreter
     // will return a string result as soon as I get the Marshall class figured out
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_sendJavascript( int texID, string js, StringBuilder result, int stringCapacity);
     // sends a string to the webview's javascript interpreter
     // will return a string result 
  
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_sendKeypress( int texID, string s);
  
  
     //
     // these functions simulate a mouse event in the webview
     //
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_mousemoved( int texID, int _x, int _y );
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_mousedown( int texID,  int _x, int _y );
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_mouseup( int texID, int _x, int _y );
  
     [DllImport ("htmlTexture")]
     private static extern void htmlTexture_leftclick( int texID, int _x, int _y );
     // leftclick = a mousemoved, mousedown, and mouseup 
  
     // 
     public int width =512;
     public int height = 512;
     Texture2D m_Texture;
     void Start() {
         m_Texture = new Texture2D (width, height, TextureFormat.ARGB32, false);
         m_Texture.Apply();
         htmlTexture_start(m_Texture.GetInstanceID(), width, height, "http://google.com");
         // put the texture on something
         transform.renderer.sharedMaterial.mainTexture = m_Texture;
     }
      
     void Update() {
         htmlTexture_update( m_Texture.GetInstanceID() );
     }
      
     void OnApplicationQuit() {
         htmlTexture_stop();
     }
     void OnMouseUp()
     {
         RaycastHit hit;
         if (Physics.Raycast (Camera.main.ScreenPointToRay(Input.mousePosition), out hit)) {
             int x = width - (int) (hit.textureCoord.x * width); 
             int y = height - (int) (hit.textureCoord.y * height); 
             htmlTexture_mouseup(m_Texture.GetInstanceID(), x, y );
         }
     }
     // 
 }
