Removing a TextField

Code (CSharp):

1. void OnGUI()
2.     {
3.         if (hammerIsInRange == true)
4.         {
5.             collectMessage = GUI.TextField (new Rect (10, 10, 200, 20), collectMessage, 25);
6.             if(inventory.hammerIsCollected == true)
7.             {
8.                 collectMessage = null;
9.                 collectedMessage = GUI.TextField(new Rect(10, 10, 200, 20), collectedMessage, 25);
10.                 StartCoroutine ("MessageDisappear");
11.                 if(removeTextBox == true)
12.                 {
13.                     Debug.Log ("the coroutine worked");
14.                 }
15.             }
16.         }
17.     }
18.  
19.     IEnumerator MessageDisappear()
20.     {
21.         yield return new WaitForSeconds (3);
22.         removeTextBox = true;
23.     }

As you can see, everything functions just fine, but I am having trouble removing the textfields I create. I try setting the collectMessage to null to remove it, but that fires a NullReferenceException. How would I remove the field so it doesn't show?

 

Set it to an empty string like so:

Code (csharp):

1. collectMessage = "";

Not sure if that is the behavior you WANT, but it won't throw nullrefs from collectMessage...
