UnigineScript is deprecated and will be removed in future releases. Please consider using C#/C++ instead, as these APIs are the preferred ones. Availability of new Engine features in UnigineScipt is not guaranteed, as the current level of support assumes only fixing critical issues.
This article describes the data/samples/objects/gui_01.cpp sample.
The gui_01 sample demonstrates how to play a video on a mesh, namely:
Assign an instance of the WidgetSpriteVideo class to the created mesh in order to play a video file
Video on the mesh created with the gui_01.cpp script
In this sample, each of 3 displays is a surface of the GUI mesh. So, the video is rendered on each of them.
Texture coordinates of both the left and right surfaces (displays) are two times larger than the texture coordinates of the central surface (display), so the video is rendered four times on each of them.
