Asset Bundle problem...

Unity Engine
1

I have been trying to use AssetBundle for some time. To my misfortune I can’t get it to work on the device.
I have created 2 bundles one for WP8 and the other for PC, the bundle contains just 3D models and NO scripts whatsoever.
The PC one works well in the editor whereas the WP8 bundle loads but does not Instantiate on device.
I have checked the logs for any sort of error or null reference but could not find anything.

Here is my code to download and instantiate the assetbundle.

void Start (){
StartCoroutine(load(loadUrl, 2));
}

private IEnumerator load(string url, int version) {
        // wait for the caching system to be ready
            using (WWW www = new WWW(url)) {
            wwwT = www; //This definition is used to get the progress which is accessed in the OnGUI
            yield return www;
            if (www.error != null)
                throw new Exception("WWW download had an error:" + www.error);
            AssetBundle bundle = www.assetBundle;
            Instantiate(bundle.mainAsset);
            Debug.Log("INSTANTIATE!");
            flag = false;
            // Unload the AssetBundles compressed contents to conserve memory
            //bundle.Unload(false);
          
        }

Thanks in Advance,

Where are your bundles stored? Are they somewhere your device can see them?

@zombiegorilla
The bundles are stored in a server and is retrieved using the above method. After retrieval the bundles are stored in the RAM as I am not saving them to a separate file location or using WWW.LoadFromCacheOrDownload.

Gotcha. I was asking because I typically store them in the local file system during dev, point the WWW to “file://”. I have on occasion forgot to switch that when I build to device. Have you tried it on other devices?

Just WP8 and PC. Have not tried on iOS and Android.

I guess that will be the same case with WP8 ?
