Add files to the documents folder when building

Unity Engine

Hi,
i know you can save files to the DataPath/Documents path when you play the game.

But for my project i need the files to be there when installing the game. So is it somehow possible to add the files to that folder when creating the build?

I tried creating a folder into the xcode build output path but it gets overridden when compiling.

Thanks,
Kiyaku

Can you create the files in an object’s Awake function in the first scene?

I guess so, kinda, i was just talking with people on the irc and i guess i can save them as text assets, put the into resources, load them at gamestart and then save them to the documents folder. Will try that out :smile:

Here is a simple javascript implementation of what Kiyaku suggested for a “description.txt” file that was imported into the Resources folder in the editor:

import System;
import System.IO;

function Awake () {
var docPath : String = Application.dataPath;
	if (Application.isEditor) {
		docPath += "/Resources/description.txt";
	}
	else {
		docPath = docPath.Substring(0, docPath.Length - 5);
	   	docPath = docPath.Substring(0, docPath.LastIndexOf("/"));
		docPath += "/Documents/description.txt";
		if (!IsFileExisting(docPath)) {
			var myText : TextAsset = UnityEngine.Resources.Load("description",TextAsset);
			WriteFile(docPath,myText.text);
		}
	}
   	ReadFile(docPath);

}

private function ReadFile(file : String) 
{  
   if(IsFileExisting(file))
   { 
      var readText : String = System.IO.File.ReadAllText(file);
      Debug.Log( readText);  
   }
   else
   { 
      Debug.Log("Error opening: " + file + " for reading."); 
      return; 
   } 
}

private function WriteFile (file : String, text : String){
	
    if (IsFileExisting(file)) 
    { 
    	Debug.Log(file+" already exists."); 
        return; 
    }
    System.IO.File.WriteAllText(file,text);
}

private function IsFileExisting(file : String) {
	return File.Exists(file);
}

Well as far as i can tell, your code requires your “description.txt” to be in the /Documents folder already.
I wanted to have it pre-installed on the iDevice, that was my problem.

But i solved it by just adding it to a variable on component and then save it to the Documents folder on start:

/* 
From Setup.cs:
iPhonePath = System.IO.Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal), "Documents"); 

public TextAsset[] iPhoneDBFiles;
*/

if(!File.Exists(Setup.Ins.iPhonePath + "/itemDB.xml"))
{
	foreach(TextAsset asset in Setup.Ins.iPhoneDBFiles)
	{
		TextWriter tw = new StreamWriter(Setup.Ins.iPhonePath + "/" + asset.name + ".xml");
	
	        tw.Write(asset.text);
	
		tw.Close();
       }
}
