www.Dispose();
}
// C# user:
IEnumerator WaitForServerResponse ( WWW www,
CallBackFunction callback)
{
yield return www;
if (www.error == null) {
Debug.Log("Successful.");
if (callback != null) {
callback(www.text);
callback = null;
}
} else {
Debug.LogError("Failed.");
}
//Clear Data
www.Dispose();
}
4. Then, we will add the SaveUserData() method, which will create WWWForm ,
set the data, and send it to the server using the WWW object. On the last line, we
will use StartCoroutine to wait for the server to finish reading the data, as
shown in the following code:
// Unity JavaScript user:
override function SaveUserData ( user : UserData ) {
_wwwForm = new WWWForm();
// Calling PHP for posting score action
_wwwForm.AddField("action","PostScore");
// Encrypt with MD5
_wwwForm.AddField("hash",MD5.Md5Sum(user.name + "-"
+ user.score.ToString() + "-" + _hashKey));
_wwwForm.AddField("score",user.score);
_wwwForm.AddField("name",user.name);
