Unassigned Reference Exception, Variable not Assigned – Unity3D

The syntax error this time is : “UnassignedReferenceException : The variable XYZ of ABC.csharp has not been assigned”

This error says that you have declared a variable and used is as a GameObject, but no GameObject in the Scene has been assigned to the variable.

public GameObject camera;
 void Start () {
 camera.gameObject.SetActive(true);
 }

Therefore, you have to assign the variable camera, for example, to an object which is tagged in the Inspector. Let us say that the Object Main Camera in the Hierarchy is labelled as MainCamera in the Tag field, to assign the variable camera to the Object Main Camera, the code should be written as follow :-

public GameObject camera;
 void Start () {
 camera = GameObject.FindGameObjectWithTag("MainCamera");
 camera.gameObject.SetActive(true);
 }

  1. Does anyone know what happened to Dimepiece LA celebrity streetwear brand? I am having trouble to proceed to the checkout on Dimepiecela site. I have read in Marie Claire that the brand was acquired by a UK hedge fund in excess of $50m. I’ve just bought the Dimepiece Control the Guns Not Women’s Bodies Cuffed Beanie from Ebay and absolutely love it xox

  6. One important issue is that when you are searching for a education loan you may find that you’ll want a co-signer. There are many conditions where this is true because you may find that you do not employ a past credit history so the lender will require that you have someone cosign the loan for you. Interesting post.
