WidgetSpriteVideo Class

You can replace the current video file with another one in run-time by using one of the following methods:

• Delete the WidgetSpriteVideo node from the node hierarchy, delete the instance of the WidgetSpriteVideo and create a new instance of the WidgetSpriteVideo in the same place, but with the different path to the required video file. Then, add the new instance to the node hierarchy.
  Notice

  There can be a small pause between deletion of the old widget and creation of a new one.
  The following example demonstrates implementation of the described method:
  Source code (UnigineScript)

  #include <core/unigine.h>
  
  /*
   */
  Gui gui;
  WidgetSpriteVideo sprite_video;
  
  /*
   */
  void create_video(string file) {
  	// create an instance of the WidgetSpriteVideo to play a given video file
  	sprite_video = new WidgetSpriteVideo(gui,file);
  	// add the created node to the node hierarchy
  	gui.addChild(sprite_video,GUI_ALIGN_OVERLAP);
  	
  	sprite_video.setLoop(1);
  	sprite_video.play();
  }
  
  /*
   */
  void destroy_video() {
  	// delete the node from the node hierarchy
  	gui.removeChild(sprite_video);
  	// delete the instance of the WidgetSpriteVideo
  	delete sprite_video;
  	sprite_video = NULL;
  }
  
  /*
   */
  int init() {
  	gui = engine.getGui();
  	
  	create_video("samples/widgets/videos/unigine.ogv");
  	thread("update_scene");
  	
  	return 1;
  }
  
  /*
   */
  void update_scene() {
  	while(true) {
  		sleep(1);
  		
  		// delete the video
  		destroy_video();
  		// create a new video
  		create_video("samples/widgets/videos/winter.ogv");
  	}
  }

• Create a new instance of the WidgetSpriteVideo on the background and disable (and then delete) the old instance of the WidgetSpriteVideo.

The following samples demonstrate the usage of the WidgetSpriteVideo class:

• gui_00
• gui_01
