i cant load assetbundle

i create a cube with a message:

#pragma strict

function Start () {
	Debug.Log("oli");
}

function Update () {

}

Then i create the unity3d file exporting via webplayer: “webplayer.unity3d”

then i try to load the file with a script in the camera:

#pragma strict

function Start () {
Debug.Log(Application.dataPath);
	var assetPath:String = "file://F:/purebaloader/Assets/webplayer.unity3d";
	var www:WWW = new WWW(assetPath);
	yield www;
	Instantiate(www.assetBundle.mainAsset);
}

function Update () {

}

and i got this message:

“The unity3d file is not a valid asset bundle.”

why!!

i want load the cube with the message and just… i cant do it

A unity3d file is a webplayer file, it’s not an asset bundle. See the documentation for how to create asset bundles:
