How do I store and retrieve data?

Hi, suppose I want to make a quiz game. I would like it to display the total percentage of players who got all the questions right.

I guess I would need the game to send info about the score to a central server and then retrieve it? But doese C2 even have this kind of functionality?

Note: using a 'scoreboard' feature of an API won't work because I would like to store numerous values - for different categories of questions or ever per question, which would mean possibly hundreds of scoreboards.

Any tips on how to best approach this?

Use the AJAX plugin to communicate with, for example, a PHP script set on your server.

You can find examples of use and more explanations about the AJAX plugin in the How do I FAQ too.

Great! Thanks, I'll do that.
