Question

Hello guys. I want to have a web camera stream in my project. I found the code and it is working perfectly. I would like to reproduce that code in C# but i lack the skills. Can anyone help out ???

// Continuously get the latest webcam shot from outside "Friday's" in Times Square
  // and DXT compress them at runtime
  var url = "";

  function Start () 
  {
   // Create a texture in DXT1 format
      renderer.material.mainTexture = new Texture2D(4, 4, TextureFormat.DXT1, false);
      while(true) 
      {
      // Start a download of the given URL
         var www = new WWW(url);

      // wait until the download is done
         yield www;

         // assign the downloaded image to the main texture of the object
         www.LoadImageIntoTexture(renderer.material.mainTexture);
       }
    }

Thanks.

Something like this should do it. (name your script "WebCam" to match the class).

using UnityEngine;
using System.Collections;

public class WebCam : MonoBehaviour
{

    public string url = "";

    void Start()
    {
        renderer.material.mainTexture = new Texture2D(4, 4, TextureFormat.DXT1, false);
        StartCoroutine(UpdateCam());
    }

    IEnumerator UpdateCam()
    {
        while (true)
        {
            Debug.Log("reloading webcam");
            WWW www = new WWW(url);
            yield return www;
            www.LoadImageIntoTexture((Texture2D)renderer.material.mainTexture);
        }
    }
}

(Edit - now tested, and bugs fixed!)

Nice code. 2 small errors. 1. You declare the variable www twice, once in the parentheses and once inside the method so you should take out the one in parentheses. 2. You need to cast mainTexture into Texture2D. Besides that perfect :)

Thanks for the pointers - fixed in the example now. Also I changed to to yield directly using the www rather than yielding null while polling www.isDone. Much neater.

Thank you. Worked like a charm :)

Why is while(true) never breaked?

because the code repeated loads the next camera frame. There's a "yield" inside the loop, so the code doesn't block the rest of your app (it releases control to the rest of your program while waiting for the next WWW to complete).
