FEWS Game application configuration

In the application configuration, global settings for the FEWS Game which are valid for all scenarios/scripts can be specified.

Schema definition

The structure of the XML-schema for the application configuration is as follows:

Explanation

The keys in the XML-schema are explained in the figure above. Some of the keys are explained in more detail here.

• The value of the key Locale must be a 2-letter abbreviation of the language in which the game will be played (e.g. EN for English or NL for Dutch).
• Historical scenarios/scripts may be familiar to players of the game. Therefore it is possible to hide the year of the scenario/script in the FEWS Game by setting the flag HideYear to true. See below for required changes in the FEWS configuration.
• The key FewsExecutable must contain the (absolute or relative) path to the FEWS executable, which is usually located in the bin-directory of a FEWS release. On the Linux platform, the FEWS executable is the shell script fews.sh. Note that for the FEWS Game a copy of the operational system should be used since some changes in the FEWS configuration are required; see below.
• The key FewsRegionDir is the (absolute or relative) path to the so-called region directory of FEWS. The region directory contains the FEWS configuration (the Config-subdirectory) and the global properties for the FEWS configuration. The FEWS Game is generic and can be used with any FEWS configuration. Note that on a Windows system, the FEWS region directory is also specified in the so-called jpif-file that is located in the bin-directory of the FEWS system. This specification must be consistent with the one in FewsRegionDir.
• The system time in FEWS is controlled by the FEWS Game. The frequency for updating the FEWS system time is specified by the key FewsSystemTimeUpdateInMinutes. See below for required changes in the FEWS configuration.
• Scenarios/scripts that can be played with the FEWS Game must be part of a scenario/script database. The key ScenarioDatabasePath contains the (absolute or relative) path to the scenario/script database.
• Events in a script can be associated with a file that is executed during the game. For example, a pdf-file can be associated with an event to simulate an incoming e-mail or an mp3-file to simulate telephone calls. Using the key FileAssociation, programs can be specified with which files with indicated extensions must be processed. Default file associations are used if nothing is specified here.
• Communication between FEWS and the FEWS Game is handled by the so-called FEWS PI service. This service requires a port number that must be specified in the section FewsPiPortNumber. See below for required changes in the FEWS configuration.
• The FEWS Game can also be played in a combined setting developed for the Dutch Water Service (Waterdienst). In such a combined setting, the hostname and the port number for connecting to the combined game must be specified in ServerHostName and ServerPort, respectively. In a stand-alone FEWS Game these keys are not relevant.

FEWS configuration

For the FEWS Game some minor changes are needed in the FEWS configuration:

• In order to hide the year within FEWS, the dateTimeFormat must be configured accordingly in the dateTime section of the FEWS configuration file Explorer.xml.
• The cardinalTimeStep, as configured in the dateTime section of the FEWS configuration file Explorer.xml, should be consistent with FewsSystemTimeUpdateInMinutes. Indeed, it makes no sense to set it in the FEWS Game to 1 minute, while it is set to 1 hour in the FEWS configuration (although this will not cause any problems in the game).
• Since all data for a scenario is pre-loaded in the FEWS local data store, it is desirable to hide certain data after the current system time, e.g. measurement data. This can be accomplished by specifying hideExternalHistoricalAfterSystemTime=true in the file global.properties, which is located in the FEWS configuration directory.
• The port number for the FEWS PI service must be in the range of port numbers that is specified in the FEWS configuration in Explorer.xml in the directory SystemConfigFiles, e.g.

  <piServicePortRange start="8100" end="8200"/>
