Scripts for applications based on the Capsis kernel (Capsis, Simeo, Xplo…) may follow several optional structures.

See the comments in the class for specific points and launch method. The app script and classpath must be adapted for your system.

The simplest way to write scripts for Capsis and the capsis kernel based apps is the type 1 structure. For specific cases, the type 2 may be useful. Type 3 is legacy and should not be used for new scripts.

Technical note: in any case, the Starter of the application (e.g. capsis.app.Starter) must be called to initialize correctly the Engine, ModelManager, ExtensionManager and the application settings. This is done by instantiating C4Script (type 1), extending C4Script (type 2) or launching the script with the Capsis launch script and the script pilot (types 1, 2, 3).

Note: The capsis launch script under Linux / MacOSX: “sh capsis.sh” and under Windows: “capsis”.
