WWW.LoadUnityWeb

Description

Loads the new web player data file.

The first level of the loaded .unity3d file will automatically be loaded. All objects, scripts and static variables from the previous .unity3d file will be unloaded. You can move information between the two sessions using PlayerPrefs class.

This function is only supported in the web player.

If the object has not finished downloading the unity3d file will not be loaded. Use isDone or yield to see if the data is available.

function Start () {
    // Start streaming the data file
    var stream =
    new WWW ("http://www.unity3d.com/Lightning/lightning.unity3d");
    // Yield until stream is done
    yield stream;
    // Load it!
    stream.LoadUnityWeb();
}

// Streams a .unity3d file and displays the progress in a GUI texture.
// You need to make sure the GUI texture is set up to have a pixel inset.
function Start() {
    // Store the original pixel inset
    // and modify it from there.
    var gt = GetComponent.<GUITexture>();

    var originalPixelRect = gt.pixelInset;

    // Update the progress bar by scaling the gui texture
    // until we reach the end
    var stream =
      new WWW ("http://www.unity3d.com/Lightning/lightning.unity3d");

    while (!stream.isDone) {
        gt.pixelInset.xMax = originalPixelRect.xMin
              + stream.progress * originalPixelRect.width;
        yield;
    }

    // Update it one last time before loading
    gt.pixelInset.xMax = originalPixelRect.xMax;

    stream.LoadUnityWeb();
}

Note that web player is not supported from 5.4.0 and later.
