Editable Text Forms in Prefabs [C#]

I'm not sure if my Title makes sense, so i will try and explain what it is i want. I did try and search for parts of my idea but nothing exact, so please if anyone can point me in the right direction i would be most grateful :

I have a set of prefabs (52) and i wish to attached editable text forms to them. In the Game scene (where the prefabs are randomly picked out) i want the text form to pop up underneth the prefab called. In the Rules scene i have built, i want the user to be able to edit text forms (before playing) , allowing them to set custom rules.

I hope i've made this clear.

How would i go by adding 52 text forms using this code?

      strUsername = GUILayout.TextField(strUsername, 20, GUILayout.Width(100));

i want this to be editable VIA a different scene

That is a big old subject!

You would need to write OnGUI code or use something like NGUI to build your editable forms.

You would need to handle selecting items - so knowing that they've been clicked on and then in the gui code you would work out the screen location from the world location of the object clicked and then try to position it underneath.

If you can cope with the GUI just appearing at one location on the screen then it would be easier.

Attach colliders to your prefabs, add a script which gets an On$$anonymous$$ouseDown to know that it has been selected - update some variable with currently selected object and use that variable in an OnGUI to know which fields to fill in on your text form.

This is not an easy thing to do, it's not that hard, but it is that tricky. Feels to me like working around on understanding GUI, choosing which way of producing GUI (NGUI, EZGUI, OnGUI in Unity), learning that component first etc would be the way to go.

Right i've sorted figured out how i can do it .. but i dont know what would be best to do ....

On my prefabs i need to add a "Read" .txt file, i was thinking about adding a script to all my prefabs but define which line to read from in the text file. So the text file will contain a line for each prefab...

In a different scene , i want to be able to save text for each prefab (each line in the text file).

I saw something that may help , but i dont know how to get it working with unity (maybe use resources folder?)

Writing to a Text File Listing 1: Writing Text Data to a File: TextFileWriter.cs

using System;

using System.IO;

namespace csharp_station.howto

{

    class TextFileWriter

    {

        static void $$anonymous$$ain(string[] args)

        {

           // create a writer and open the file

            TextWriter tw = new StreamWriter("date.txt");



            // write a line of text to the file

            tw.WriteLine(DateTime.Now);



            // close the stream

            tw.Close();

        }

    }

}

Reading From a Text File

Listing 2 shows how to read from a text file: Listing 2: Reading Text Data from a File: TextFileReader.cs

using System;

using System.IO;

namespace csharp_station.howto

{

    class TextFileReader

    {

        static void $$anonymous$$ain(string[] args)

        {

            // create reader & open file

            Textreader tr = new StreamReader("date.txt");


            // read a line of text

            Console.WriteLine(tr.ReadLine());


           // close the stream

            tr.Close();

        }

    }

}
