Miniature

You love chess. You love Maemo and its devices. You believe they fit so well... yet you haven't found a convincing implementation of a chess game for Maemo. Miniature to the rescue!

The concept

More or less:

  • The main use case is playing online against other players at freechess.org
  • Now imagine that you can also chat with the other player.
  • Playing against the computer is a given (chat is optional)
  • Learning is important and it would be great to watch games, review stored games and also process offline the lessons given at certain times in freechess.org
  • A variant would be to play against othe player with a compatible device via local network or bluetooth.
  • I guess if we got at this point then implement variants such as suicide chess, random house, etc is peanuts.

Basing this on Qt 4.6 would be useful to assure the Fremantle - Harmattan path, be fully compliant with whatever the Ovi store brings and have ports for Symbian, Windows Mobile and desktop OSs (Linux, Windows, Mac).

Project status

Kicking off. Nothing exists. Just a Talk thread, a Garage project and this wiki page.

The developer mailing list is chess-developer@garage.maemo.org

Technology selections

How to make the most from existing free projects avoiding forking and duplicated work as much as possible.

  • Qt 4.6 for UI layer. The goal is to have Maemo as primary development platform, aiming for straight ports to Symbian and other Qt compatible platforms.
    • Can we save work by looking at pacaq and Knights? Others? --qgil 06:22, 3 November 2009 (UTC)
  • What starting point to get the online chess features?
  • What starting point for chatting?
  • What starting point for game analysis?

Architecture

Logic:

  • Game - the logic for a particular game, right now that would be just chess, but other board games could be possible too. (Chess based or other)
  • Pre-Game - How to find players, select a server or engine

Domain:

  • Board - Represents the data structure of the board (duh)
  • Player - information about the other player, like online status, skill level

Communication:

  • ICS
  • Bluetooth
  • Telepathy
  • Computer Chess Engine - an offline engine should be accessed the same way any online game is, the engine does not have to be in the same task
