Question by jann1 · Apr 10, 2014 at 03:12 PM · nullreferenceexceptionfunctionnull

access GameObject only when instantiated

Hi, Im using a GetComponent and it is giving me a null reference because the object has not been instantiated. I tried this

 if (GameObject.Find("MyObject")){
       GameObject go = GameObject.Find ("MyObject");
   MyScript myScript = (MyScript)go.GetComponent (typeof(MyScript));
       }

and it works but then Id have to include the functions with the variables from the other script into this and that would result in a super complicated and ugly code.

I could also do something like this

 if (GameObject.FindWithTag("MyObject") == null) {}

but how would I make the function stop until the GameObject is found? Thanks.

Hi again, I found out this wasnt working because I was using the Update function, which cannot be blocked. So I created a new function which contains the code I want to execute, only when four different GameObjects are found. My thought was to do it like this:

 if (GameObject.FindWithTag ("Object1") && GameObject.FindWithTag ("Object2") && GameObject.FindWithTag ("Object3") && GameObject.FindWithTag ("Object4"))

and then call the function. This looks strange and is also not working. How would I make this work?

All right I solved it! It turned out that I used Find ("Object1") in a place even though they were created as Object1(clone). I changed it to FindWithTag and it worked like a charm.
