Datastore-server is a Google App Engine web application written in Python which allows you to manage game high scores remotely.
After that, open Google App Angine, login with a Google account and create a new application with the name you want for your highscores server, for example, MyGameScoresSystem.
Finally, go to the datastore-server folder and upload the application following this tutorial.
Your application should be ready to be accessed by opening http://yourapplicationid.appspot.com
Congratulations, you have your Google App Engine high scores application ready :D
After the web application is installed, you will need to create a Game key to be used inside your game to identify it uniquely on datastore-server.
To do so, open your application at http://yourapplicationid.appspot.com, and Sign in with your Google account.
Now, fill the new Game form by setting a key and a name. The key is a string, in our case we are creating it by calculating the md5sum of the game's name, for example, key = md5sum("Minecraft"), and name = Minecraft. Click submit and you will have a game created.
The application has different webservices, to simplify usage if you are using Java, there is a Java library named datastore which encapsulates all http requests through a simple API.
If you are using another language or want to access directly to those web services, you will have to wait we write a guide for them.
TODO: Write docs specifying which web services exists and how to access them.
It also has some pages to help you manage the game scores,
The main page which shows a list of games and lets you create new games, at
Profiles page, shows you all registered profiles at
Game scores page, shows you all scores of one specific game, at
/game with the following parameters:
gameKey - required - the key of the game. tag* - optional - one tag the scores has to have in order to be listed, could be used multiple times. distinct - optional - filter one score per profile, true by default. range - optional - day/week/month to request for daily/weekly/monthly scores respectively, all scores by default. rangeNumber - optional - specify which day/week/month of the year, by default uses current day/week/month.
That's all for now, explore the API by yourself and feel free to suggest enhancements and or bugs in the Issues page.
