Why the state of the member array of the class isn't maintained outside the function it is initialized in?
I have an array of GameObject inside the class which is initialized in a method and given certain number of elements inside that method, however when that particular array is accessed outside the class it's initialized in, the array turns out totally empty. Another thing is the certain variables are public and assigned in inspector, despite of all that the console warns of unassigned public variables and causes mess. Attached pictures would illustrate what i mean.

Can you tell us what lines it complains about unassigned public variables for? And what do you mean by causes mess?
I don't see the relation between the screenshots attached. Can you post the exact errors, as text? Use the 101010 button in the toolbar to post code.

quest = new GameObject[Total_Questions];
for (int i = 0; i < Total_Questions; i++)
{
quest[i] = (GameObject)Instantiate(QuestionPanel);
quest[i].transform.SetParent(Parent.transform, false);
quest[i].GetComponentInChildren<Text>().text = myDataset.Tables["ObsessionsQuestions"].Rows[i]["Question"].ToString();
Text txt = quest[i].transform.Search("Example");
txt.text = myDataset.Tables["ObsessionsQuestions"].Rows[i]["Example"].ToString();
}
GameObject mybutton = (GameObject)Instantiate(next);
mybutton.transform.SetParent(Parent.transform, false);
}
public void test()
{
Debug.Log(quest.Length.ToString());//this report 0 elements in console
for (int i =quest.Length; i >= 0;i--)
{
Destroy(quest[i].gameObject); // and this throws indexoutofrangeexception;
}
}
}
}
the variables QuestionPanel,next,Parent are assigned in inspector, the quest array is initialized in FillQuestions() method. The test() method is triggered by button, when this test() method is triggered it throws indexoutofrangeException,and debug.log(quest.length.Tostring()) shows 0 elements in quest.
