engine.oculus Functions
This set of functions is available when the AppOculus plugin is loaded.
If the plugin is loaded together with the engine, the HAS_APP_OCULUS 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:
Source code (UnigineScript)
#ifdef HAS_APP_OCULUS
// engine.oculus functions
#endif
