engine.vive Functions
Warning
The scope of applications for UnigineScript is limited to implementing materials-related logic (material expressions, scriptable materials, brush materials). Do not use UnigineScript as a language for application logic, please consider C#/C++ instead, as these APIs are the preferred ones. Availability of new Engine features in UnigineScript (beyond its scope of applications) is not guaranteed, as the current level of support assumes only fixing critical issues.
This set of functions is available when the AppVive plugin is loaded.
Notice
AppVive plugin cannot be used in a Qt-based application.
If AppVive is loaded together with the engine, the HAS_APP_VIVE 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_VIVE
// engine.vive functions
#endifThe source code of OpenVR can be found here.
The full set of Vive devices is described here.
