Title: OGS Mahjong 2: Demo 2 Date: 2018-10-02 00:00 Category: News Slug: mahjong-demo2 Lang: en

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.

Release

Run the latest version of OGS Mahjong 2 in your web browser: http://ogstudio.github.io/ogs-mahjong

You are encouraged to run the game with seed parameter like this: http://ogstudio.github.io/ogs-mahjong?seed=0

This allows you to play the same layout each time you launch the game.

Each seed uniquely identifies the placement of tiles. Thus, different seeds give you a different experience.

Development techniques and foundation

During the second demonstration development, we switched from standard development to example-driven one. This resulted in the creation of three distinct repositories to back the development of OGS Mahjong 2:

• OpenSceneGraph cross-platform examples repository provides cross-platform foundation like resource handling, render window setup, etc.
• OGS Mahjong components repository provides Mahjong specific functionality like parsing layout, matching tiles, etc.
• OGS Mahjong repository contains snapshots of OGS Mahjong components features that comprise specific game version. E.g., Demo 2 version is almost identical to 05.ColorfulStatus example of OGS Mahjong components.

Beyond Mahjong solitaire

In addition to seed parameter, you can let the game use remote layout hosted at GitHub: http://ogstudio.github.io/ogs-mahjong?seed=0&layout=github://OGStudio/ogs-mahjong-components/data/cat.layout

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.

Our next step is to turn game logic into a resource, too.
