<section1 topic='Introduction' anchor='intro'>
|
|
<p>
|
|
It is quite common to play games over IM networks.
|
|
Since Tic-tac-toe is a well-known and simple game,
|
|
it's a good example for a server-based game protocol.
|
|

|
<section1 topic='Requirements' anchor='reqs'>
|
|
<p>
|
|
This document addresses the requirements for a game protocol as defined by &xep-mug;.
|
|
In particular this consists of:
|
|
</p>
|
|
<ol start='1'>
|
|
<li>game roles</li>
|
|
<li>match state</li>
|
|
<li>turns</li>
|
|
<li>match configuration</li>
|
|
<li>conditions for interrupting and terminating a match</li>
|
|
</ol>
|
|
<p>
|
|
The extensions needed to implement these requirements are qualified by the 'http://jabber.org/protocol/mug/tictactoe' namespace.
|
|
</p>
|
|
</section1>
|
|
|
|
<section1 topic='Discovering Support' anchor='support'>
|
|
<p>
|
|
An entity implementing this protocol MUST also support &xep-mug; and answer to disco requests accordingly
|
|
including both the Multi-User Gaming and the game &FEATURE; elements in the response.
|
|

<section1 topic='Game Roles' anchor='roles'>
|
|
<p>
|
|
A Tic-tac-toe game uses two game roles, "x" and "o".
|
|
Both roles have to be assigned to exactly one player to start a match.
|
|
If one role gets unassigned or a player gets unavailable the match has to be paused.
|
|
</p>
|
|
</section1>
|
|
|
|
<section1 topic='Match Configuration' anchor='config'>
|
|
<p>
|
|
A service SHOULD offer a configuration form with the following options:
|
|
</p>
|
|
<ol start='1'>
|
|
<li>starting role ("mug/tictactoe#config_first")</li>
|
|
<li>size of the board ("mug/tictactoe#config_rows" and "mug/tictactoe#config_cols")</li>
|
|
<li>the number of marks in a row needed to win ("mug/tictactoe#config_first")</li>
|
|
</ol>
|
|
<p>
|
|
An implementation MUST be able to handle the a board with three cols and rows
|
|
and three respective marks to win.
|
|
Everything beyond that is OPTIONAL.
|
|

<section1 topic='Match State' anchor='state'>
|

<p>
|
|
The state in a Tic-tac-toe match represents the match configuration,
|
|
the player who makes the next turn
|
|
and the current state of the board. Every state is distributed to all occupants.
|
|

<p>

The match is considered terminated when the board is full or
|
|
when one player reaches the number of respective marks as defined by the strike option.
|
|
After termination the service broadcasts the final state including either a <draw>
|
|
or <won> (including a game role) element to indicate the resulting score
|
|
and the initial state of the next round.
