<p>We are glad to announce the release of the second demonstration of OGS Mahjong 2. The purposes of this release were to refine our development techniques and build a solid cross-platform foundation.</p>
<p><strong>Release</strong></p>
<p>Run the latest version of OGS Mahjong 2 in your web browser: <a href="http://ogstudio.github.io/ogs-mahjong">http://ogstudio.github.io/ogs-mahjong</a></p>
<p>You are encouraged to run the game with <code>seed</code> parameter like this: <a href="http://ogstudio.github.io/ogs-mahjong?seed=0">http://ogstudio.github.io/ogs-mahjong?seed=0</a></p>
<p>This allows you to play the same layout each time you launch the game.</p>
<p>Each seed uniquely identifies the placement of tiles. Thus, different seeds give you a different experience.</p>
<p><strong>Development techniques and foundation</strong></p>
<p>During the second demonstration development, we switched from standard development to <a href="example-driven-development.html">example-driven one</a>. This resulted in the creation of three distinct repositories to back the development of OGS Mahjong 2:</p>
<ul>
<li><a href="https://github.com/OGStudio/openscenegraph-cross-platform-examples">OpenSceneGraph cross-platform examples</a> repository provides cross-platform foundation like resource handling, render window setup, etc.</li>
<li><a href="https://github.com/OGStudio/ogs-mahjong-components">OGS Mahjong components</a> repository provides Mahjong specific functionality like parsing layout, matching tiles, etc.</li>
<li><a href="https://bitbucket.org/ogstudio-games/ogs-mahjong">OGS Mahjong</a> repository contains snapshots of <code>OGS Mahjong components</code> features that comprise specific game version. E.g., <code>Demo 2</code> version is almost identical to <a href="https://github.com/OGStudio/ogs-mahjong-components/tree/master/05.ColorfulStatus">05.ColorfulStatus</a> example of <code>OGS Mahjong components</code>.</li>
</ul>
<p><strong>Beyond Mahjong solitaire</strong></p>
<p>In addition to <code>seed</code> parameter, you can let the game use remote layout hosted at GitHub: <a href="http://ogstudio.github.io/ogs-mahjong?seed=0&amp;layout=github://OGStudio/ogs-mahjong-components/data/cat.layout">http://ogstudio.github.io/ogs-mahjong?seed=0&amp;layout=github://OGStudio/ogs-mahjong-components/data/cat.layout</a></p>
<p>Utilizing remote resources is an extremely powerful approach allowing anyone to create a layout of his/her choice and see the layout in action instantly.</p>
<p>Our next step is to turn game logic into a resource, too.</p>
