Trying to SetActive specific children based on public static int

Archived Forums Questions & Answers

The following script is attached to a GameObject with many children (Unity 4.6 GIU text objects). I want to turn them on (child welcomeText in this case) or off based on a public static int nextNum which I already have working. I’d like to stick to using the public static int nextNum as I want to sequence animation events aswell as the text objects. The program runs but then pauses with the following error, plus a number of objects in the scene disappear.

using UnityEngine;
using System.Collections;

public class welcomeTextControl : MonoBehaviour

{
	void Start ()
	{
		GameObject.Find("welcomeText").SetActive(false);
	}

	void Update ()
	{
	if (SetButInc.nextNum == 1)
		{
			GameObject.Find("welcomeText").SetActive(true);
		}
	else
		{
			GameObject.Find("welcomeText").SetActive(false);
		}

	}
}

Error: NullReferenceException: Object reference not set to an instance of an object
welcomeTextControl.Update () (at Assets/Scripts/welcomeTextControl.cs:20)

Managed to fix it;

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class welcomeTextControl : MonoBehaviour
{	
	public GameObject welcomeText;

	void Start()
	{
		welcomeText.SetActive (false);
	}

	void Update ()
	{
		if (SetButInc.nextNum == 1)
		{
			welcomeText.SetActive(true);
		}
		else
		{
			welcomeText.SetActive(false);
		}

	}
}
