-Use `app.setShowSettings(true);` to present the user with a splashscreen and the built-in display settings dialog when starting the game; or use `app.setShowSettings(false);` to hide the built-in screen (in this case, you may want to provide a custom splashscreen and settings panel). Set this boolean before calling `app.start()` in the `main()` method of the SimpleApplication. See also xref:jme3/intermediate/appsettings.adoc[AppSettings].
