Project Title: Pidgin plugin for PySoy
Student: Mayank Singh
Organization: Python Software Foundation
This project aims to refine/extend the User Gaming extension to XMPP (XEP - 0196) and utilize it in a plugin for pidgin to handle game notifications with pysoy games as an example. The plugin will add the ability to launch games directly from the xmpp client as well as other features like listing currently running games and a possible multiplayer lounge using MUC (XEP - 0045). The XEP - 0196 is highly dependent on the Personal Eventing Protocol (XEP - 0163) and will act as a natural extension to that.
Ideas for the XEP-0196:
- As is clear from the current deferred specification of the XEP - 0196, it is too specifc to Massively Multiplayer Online Games like World of Warcraft.
- The specification I plan to build aims to contain elements that are common to any type of game.
- A possible table defining child elements for the <game> element which propagates game notification:
Element Description Example Datatype Inclusion name The name of the game Ping pong xs:string REQUIRED uri URI to launch the game http://220.127.116.11/gameno123.ext xs:anyURI OPTIONAL description Any other text to be broadcasted Three slots left. Join xs:string OPTIONAL web_resource Some web link related to the game http://www.randomgame.com xs:anyURI OPTIONAL
- Transport mechanism could be quite similar to the current one.
- I will use the wiki (additional link) to describe more ideas regarding this.
The planned implementation for the plugin should work like this:
- A pysoy client acting as a "game server" starts a game and it connects to the xmpp server to broadcast to all its subscribers that a game is being played in the form of status notifications.
- People running pidgin clients see this on this person's status message, who launched the pysoy server.
- They start a conversation with this fellow.
- If they have the correct plugin activated, they'll be able to find an option for launching the game via an external client that can be determined by the mime type of the resource in the uri.
- The plugin's menu should have options to list all games being played by a user's friends, launch a multiplayer lounge(MUC) for a particular multiplayer game, etc.
The visible changes to the UI of pidgin will be:
Change of status to a proper game notification.
Addition of game elements to the conversation menu if the plugin is activated:
The part of the pidgin plugin is only to provide the ability to launch the game being played by a member of a person's roster using possibly a URI provided by the xmpp data transmitted from the player's end. The part of broadcasting the game notification falls under the area of the libsoy's built-in xmpp client.
The xmpp data being broadcast by the various friends on a person's roster can be collected and represented as submenu items to a menu item "List all games" or in a separate window allowing the user to select and join the game he wishes to play.
Using the same xmpp data, we can create separate multiplayer lounges for players interested in the same game with a listing of currently ongoing games indicating which games are full and cannot be joined and which need more participants and can be joined. Also, I can provide an MUC facility for onlookers who haven't yet joined a game and are waiting for a game to start. The difference between this feature and the above feature is that the above feature lists all games, be it of any type. However, this feature aims to create separate lounges for different games.
