When you attach the script to an object in Unity3d, you should see the public vars in the object explorer. Make sure you drag the bullitPrefab to that script, so Unity3d knows which prefab to use in bullitPrefab . It now says (None), but it should be bullitPrefab .
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
