I would like to create a configuration file, use the "config.xml", but can not on the "Documents" directory. How can I do? I tried on the "Resources", but Build, it disappeared.

Application.dataPath return don't contain "myappname.app".

like:/var/mobile/Applications/2808624E-16E7-4AC9-8771-C9241248F69F/Data

I created a "/myappname.app/config" directory, put the configuration file into?

I have a text file in Resources/English.txt with:

Code:

[EnergyTank]
(You found an energy tank)

[Hotspot|CNBO|10]
We made it!
Now lets get out of here.

[Hotspot|CNDN|1]
Look, over here!
A checkpoint, finally.
Save your progress
before something terrible happens.

[Fallen|CN|1]
Looking up or down while standing still
may reveal lurking enemies, threats,
and other secrets.
Can you see the orb up there?

[Fallen|CN|2]
You can enter doors on ceilings
by shooting straight up
and jumping into to them.

And use this to read from it:

Code:

using UnityEngine;
using System.Collections;

public class TextTable {

public static string[] GetLines (string id) {
   ArrayList lines = new ArrayList();
   string line;
   TextAsset textFile = (TextAsset)Resources.Load("English", typeof(TextAsset));
   System.IO.StringReader textStream = new System.IO.StringReader(textFile.text);
   string lineID = "[" + id + "]";
   bool match = false;
   while((line = textStream.ReadLine()) != null) {
      if (match) {
         if (line.StartsWith("[")) {
            break;
         }
         if (line.Length > 0) {
            lines.Add(line);
         }
      }
      else if (line.StartsWith(lineID)) {
         match = true;
      }
   }
   textStream.Close();
   if (lines.Count > 0) {
      return (string[])lines.ToArray(typeof(string));
   }
   return new string[0];
}
}

Ignore the parsing part, the loading is what may be of interest to you.

If you put a .txt file into the Resources directory it doesn't show up as a file with the same name in any directory.

If you want to write to a file in the Documents directory on the iPhone you have to modify the path returned by Application.DataPath.

Code:

string docsPath = Application.dataPath.Replace("/Data", "/Documents");

It's okay that this path doesn't contain your app's name. The GUID is what's needed.

I've only tested the ReadFile function, but these should work for modifying files in the Documents directory. All other directories on the iPhone are read only.

Code:

using UnityEngine;
using System.Collections;
using System.IO;

public class FileUtilities {

public static byte[] ReadFile(string path) {
   Debug.Log("Attempting to read file "+ path);
   FileStream fs = new System.IO.FileStream(path, System.IO.FileMode.Open, System.IO.FileAccess.Read);
   byte[] thebytes = new byte[(int) fs.Length];
   fs.Read(thebytes, 0, (int) fs.Length);
   fs.Close();

   return thebytes;
}

public static void WriteFile(string path, byte[] bytes) {
   Debug.Log("Attempting to write file "+ path);
   FileStream fs = new System.IO.FileStream(path, System.IO.FileMode.Create);
   fs.Write(bytes, 0, bytes.Length);
   fs.Close();
}

public static bool FileExists(string path) {
   return File.Exists(path);
}
}

Did you see this thread? They were successful loading files from the app bundle:
http://forum.unity3d.com/viewtopic.php?t=37510

I don't know if it's possible to write files to the app bundle though. OS might not allow it.
