WWW won't load file from webplayer

Dear co-uniters,

I’d like to read configuration data from a text file on the server. I’m using this simple script:

	string conf_file = Application.dataPath + "/config.txt";
	WWW www = new WWW(conf_file);

	float time_start = Time.realtimeSinceStartup;
	while (!www.isDone && Time.realtimeSinceStartup < time_start + 5.0f) { };

	if (!www.isDone)
		return "Could not load '" + conf_file + "'";
	else
		return www.text;

I’ve done these things from a standalone app without problems, but built as webplayer I keep getting the ‘could not load’ error, whether I run it locally or on a server. The text file is in the same dir as the .unity3d file and is accessible (at least I can open it in the browser).

Does anyone know what I’m doing wrong?

Replace your download code first. I have an impression that this monster might be blocking it all in web player

while (!www.isDone && Time.realtimeSinceStartup < time_start + 5.0f) { };

Declare IEnumerator in your C# class, like this:

IEnumerator WaitForDownload() {
    string conf_file = Application.dataPath + "/config.txt";
    WWW www = new WWW(conf_file);
    yield return www; 

    // Now we can access the loaded text
    result = www.text;
}

And you need to call this as a coroutine. Place the following line where you need a config request to be made.

StartCoroutine("WaitForDownload");

You'll be able to access the config if you run this on server (and make sure it's accessible by URL from browser).

Have fun!
