How do I resolve NullReferenceException ??

Questions & Answers
1

I’m trying to access a public variable from another script and I’m getting a NullreferenceException.

I’ve searched for and read many of the 150+ pages on the issue and I think I can get around it with a “FInd” but I’m having a hard time with the syntax…I can’t find any examples that are on point with the syntax I need.

Here’s the Variables I want to access:

public class GameVars : MonoBehaviour 
{
	public int RedStrength;
	public int BlueStrength;
}

BUT…when I try to access them from another script I get the null reference error.

Here is one example of the “Find” I’ve tried in another script…and I’ve tried different combination/variations of syntax from LOTS of “answers” but none seem to be what I need.

	void Awake()
	{
		GameObject go = GameObject.Find ("BlueStrength");
		go.GetComponent<GameVars> ().BlueStrength;
	}

ODDLY…I was able to access this variable from the other script for awhile (without using any sort of “find”) but then I must have changed something that triggered the Null Exception error and now even though I’ve tried to replicate the problem free code I still get the error.

Thanks in advance for any help.

hi;

try to find it by the type of it and not with name like this :

GameObject.FindObjectOfType<GameVars>().BlueStrength;

======================

so what are u doing in this lane ?

go.GetComponent<GameVars> ().BlueStrength;

u are just getting an access to an int but not doing any thing or assign it to another int ;
