Unity Custom Editor GUI

Question

I'm having an issue adding new values in fields after they are created in Editor, they keeping coming back and if i enter a new one it will display the first value. Can anyone give me snippet of code how can i add values which will be automatically saved.

Thanks!

    GUILayout.BeginHorizontal();
    GUILayout.BeginVertical();
    addInteger = GUILayout.Toggle(addInteger, "Integers");
    howMuchIntegers = EditorGUILayout.IntField(howMuchIntegers);
    intNames = new string[howMuchIntegers];
    if (addInteger)
    {
        if (howMuchIntegers != 0)
        {
            GUILayout.BeginVertical("box");
            for (int i = 0; i < howMuchIntegers; i++)
            {
                intNames[i] = i.ToString();
                intNames[i] = EditorGUILayout.TextField(intNames[i]);
            }
            GUILayout.BeginVertical("box");
        }
    }
    GUILayout.EndVertical();
    GUILayout.EndHorizontal();

Still won't alow me to update values it reverts them back to null as they are. — CodeLazarus

Second question. So you have this part intNames = new string[howMuchIntegers]; What happens if you remove this from the OnGui() section, and instead put it in just the class, or in the Start(). I think this part is getting called every update and is overwriting whatever you just saved. — Tyler S. Loeper

I want to type the values in those fields and to be saved in the array intNames[]; — CodeLazarus

I think your data is getting overwritten in 2 places.

Here,

intNames = new string[howMuchIntegers];

and here,

intNames[i] = i.ToString();

So here is one solution. Basically I just suggest that you extract the parts that don't need to be run 60 times a second, you can do this however you want.

 bool firstTimeRun = true;

 void OnGUI()
 {    
    GUILayout.BeginHorizontal();
    GUILayout.BeginVertical();
    addInteger = GUILayout.Toggle(addInteger, "Integers");
    howMuchIntegers = EditorGUILayout.IntField(howMuchIntegers);

    if(firstTimeRun)
    {
        intNames = new string[howMuchIntegers];
        if (addInteger)
        {
            if (howMuchIntegers != 0)
            {
                GUILayout.BeginVertical("box");
                for (int i = 0; i < howMuchIntegers; i++)
                {
                    intNames[i] = i.ToString();
                    intNames[i] = EditorGUILayout.TextField(intNames[i]);
                }
                GUILayout.BeginVertical("box");
            }
        }

        firstTimeRun = false;
        GUILayout.EndVertical();
        GUILayout.EndHorizontal();
    }
    else
    {
        if (addInteger)
        {
            if (howMuchIntegers != 0)
            {
                GUILayout.BeginVertical("box");
                for (int i = 0; i < howMuchIntegers; i++)
                {
                    intNames[i] = EditorGUILayout.TextField(intNames[i]);
                }
                GUILayout.BeginVertical("box");
            }
        }
        GUILayout.EndVertical();
        GUILayout.EndHorizontal();
    }
 }
