Can't load asset bundle.

Unity Engine
1

Hi,
I’m new to using unity and javascript so please bear with me.

I’m triggering a download of an asset bundle (which only contains a sphere prefab) which I think is working fine. I created the asset bundle by using the Export Resource editor script and uploaded it to a server. I’m simply trying to load the sphere into my scene as the player is moving around to test the use of asset bundles. This is what is causing me problems.

I have the following code:

var download : WWW;
var url = "someServer";
private var assetBundle : AssetBundle;

function OnTriggerEnter(){
	var download = WWW(url);
	yield download;
	Debug.Log("Asset downloaded.");
	assetBundle = download.assetBundle;
	assetBundle.Unload(true);
}

I get the following errors:

Failed to load asset bundle
UnityEngine.WWW:get_assetBundle()

NullReferenceException

Can anyone please help?

Solved. It seems I have to ensure the URL must end in .unity3d.
