C# 클래스 MrGravity.WorldSelect

Checks if a save file for the game already exists - and loads it if so. Meant to be used solely on XBOX360. Should be used as soon as we know what PlayerIndex the "gamer" is using (IE right after the title screen). Note: if a save game does not exist the constructor for this class should have filled in the default values (0 stars, all but the first locked - on xbox our default xml file should always have the default values - we cannot save information to that file as it is a binary xnb file that can't be changed at run time) Do not call this until we know the PlayerIndex the player is using!

Saves level unlock and scoring information PC saving is straightforward - but xDoc.Save() will not work on xbox360. Instead we use the built in XmlSerializer class to serialize an element out to an xml file. We build our Xelement like normal - but instead of saving that directly using XDocument.Save() we place this XElement into a struct, and use XmlSerializer to serialize the data out into a storage device on the xbox.
