Unigine::Plugins::AppVarjo Class
| Header: | #include <plugins/UnigineAppVarjo.h> |
This set of functions is available when the AppVarjo plugin is loaded.
Notice
AppVarjo plugin cannot be used in a Qt-based application.
If AppVarjo plugin is loaded together with the engine, the HAS_APP_VARJO definition is set. This definition can be used, for example, to avoid errors if the plugin is not loaded; the code in which the plugin functions are executed can be wrapped around as follows:
