/* WebTextFileChecker.cs
This checks the text in a text file on the web - believe it!

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class WebTextFileChecker:MonoBehaviour
{
public void Start()
{
StartCoroutine(Check());
}
private IEnumerator Check()
{
WWW w = new WWW("http://yourserver.com/handyFile.txt");
yield return w;
if (w.error != null)
{
Debug.Log("Error .. " +w.error);
// for example, often 'Error .. 404 Not Found'
}
else
{
Debug.Log("Found ... ==>" +w.text +"<==");
// don't forget to look in the 'bottom section'
// of Unity console to see the full text of
// multiline console messages.
}
/* example code to separate all that text in to lines:
longStringFromFile = w.text
List<string> lines = new List<string>(
longStringFromFile
.Split(new string[] { "\r","\n" },
StringSplitOptions.RemoveEmptyEntries) );
// remove comment lines...
lines = lines
.Where(line => !(line.StartsWith("//")
|| line.StartsWith("#")))
.ToList();
*/
}
}
1) Use myWWW = WWW(url); to fetch data from your server.
2) Parse the resulting string for the data segments you need. myWWW.text
You will probably need a couple of helper functions.
wwwStr2Array() converts a string you might get from your WWW fetch to an array. http://answers.unity3d.com/questions/33243/array-dump-to-string-for-send-via-www/33351#33351
You can use the same idea if your WWW returns a string like: username=fred&password=flintstones - you would just put it through the delimiter split in the above link again.
Once your values are in arrays, you can just manipulate them as you would usually.
This Does not work on iPADs. Do you have any other option?
You could also use uQuery:
uQuery.Get("http://url.to/file.txt", function(data, xhr) {
Debug.Log(data); // Prints the text
});
