Hi everyone,

I'm a newbie and I just learn unity3d from learning module and I try to create 2D ufo tutorial, after I follow the tutorial video and play it, I found error message like this :

UnassignedReferenceException: The variable player of CompleteCameraController has not been assigned.
You probably need to assign the player variable of the CompleteCameraController script in the inspector.UnassignedReferenceException: The variable player of CompleteCameraController has not been assigned. Erroru13


If I see the video tutorial there is nothing error happen, why my game got error? can anyone please give me some solution and thanks. I attach the screen shoot.
