Eventually I hope to distribute the game I’m building, and users will want to save their game state somewhere. It seems from this tutorial that a good place to do that is in the assets folder:
Generally, I’d always try and use javas built-in property file support… For small amounts of data you can store binary data even, using uuencode or similar to convert the data to plain text. This way assures that you can always save the data on any platform even in a platform-specific manner because its built into the java spec.
Oops, I just wrote wrote this code a few days ago as a test and put it up on the wiki. It wasn’t meant to suggest the “assets” as the path. I’ll update it with what Sploreg said.
