Question by greasybear · Nov 07, 2016 at 07:41 AM · c#null referenceterminal

Can anyone help me as to why this is a null reference?

 else if (s.Equals("magic"))
             {
                  GameObject fps = GameObject.FindWithTag("Player");
                   Inventory inventory = fps.GetComponent<Inventory>();  
                   return string.Join("\n", 
                       inventory.cliObjects.Select(edit => edit.name).ToArray());

My player objects adds public objects to the script Inventory. I have the above code on an interactive terminal that should list these objects upon typing "magic". All that is coming up is a null reference. Can anyone help with why that is? Am I searching for the objects incorrectly?

Have you tried using Debug.log to see if you actually catch something, and know which one returns a null? You could do something like:

  else if (s.Equals("magic"))
              {
                   GameObject fps = GameObject.FindWithTag("Player");
 Debug.log("Player object is " + fps);
                    Inventory inventory = fps.GetComponent<Inventory>();  
 Debug.log("Inventory is "+ inventory);
                    return string.Join("\n", 
                        inventory.cliObjects.Select(edit => edit.name).ToArray());


That should give you an idea of what is actually going on, if it's the fps object that is null, or inventory :)
