AssetBundles let you stream additional assets via the WWW class and instantiate them at runtime. AssetBundles are created via BuildPipeline.BuildAssetBundle.

Note that bundles are not fully compatible between platforms. A bundle built for any of the standalone platforms (including webplayer) can be loaded on any of those platforms but not on iOS or Android. Furthermore, a bundle built for iOS is not compatible with Android and vice versa.

See Also: WWW.assetBundle, Loading Resources at Runtime, BuildPipeline.BuildAssetBundle.

function Start () {
	var www = WWW ("http://myserver/myBundle.unity3d");
