Unigine.WidgetSpriteVideo Class

Inherits from: WidgetSprite

This class is used to create a virtual monitor that plays a video file (currently only *.OGV files are supported). It can be synchrozied with playback of the ambient sound or the directional sound source.

The following example illustrates how to play a video-file on the system GUI or a GUI object using the WidgetSpriteVideo class.

Create a new C# component named VideoSprite and copy the code below:

Source code (C#)
using System;
using System.Collections;
using System.Collections.Generic;
using Unigine;

[Component(PropertyGuid = "AUTOGENERATED_GUID")] // <-- this line is generated automatically for a new component
public class VideoSprite : Component
{
	// path to the video file to play (only *.OGV type is supported)
	[ParameterFile(Filter =(".ogv"))]
	public String file_name;

	// sprite video widgets
	WidgetSpriteVideo TVscreen;
	WidgetSpriteVideo MAINscreen;

	private void Init()
	{
		// creating the first sprite video widget that plays a file_name video file on the system GUI
		MAINscreen = new WidgetSpriteVideo(Gui.GetCurrent(), file_name, 1);

		// setting size and position of the second sprite video widget on the screen
		MAINscreen.SetPosition(100, 100);
		MAINscreen.Width = 400;
		MAINscreen.Height = 225;
		MAINscreen.Arrange();

		// adding the sprite video widge to the system GUI
		Gui.GetCurrent().AddChild(MAINscreen, Gui.ALIGN_OVERLAP | Gui.ALIGN_BACKGROUND);

		// setting looped playback mode
		MAINscreen.Loop = 1;

		// launching playback
		MAINscreen.Play();

		// checking if the node to which the component is assigned is a GUI Object
		if(node.Type != Node.TYPE.OBJECT_GUI)
		{
			Log.Message("Node is not a GUI Object!\n");
			return;
		}
		ObjectGui GUIObject = node as ObjectGui;

		// creating the second sprite video widget that plays a file_name video file on the GUI object
		TVscreen = new WidgetSpriteVideo(GUIObject.GetGui(), file_name, 1);

		// adjusting the size of the widget to fit the size of the GUI object
		TVscreen.Width = GUIObject.ScreenWidth;
		TVscreen.Height = GUIObject.ScreenHeight;

		// adding the sprite video widget to the GUI object
		GUIObject.GetGui().AddChild(TVscreen, Gui.ALIGN_OVERLAP | Gui.ALIGN_BACKGROUND);

		// setting looped playback mode
		TVscreen.Loop = 1;

		// launching playback
		TVscreen.Play();
	}
	
	private void Update()
	{
		// write here code to be called before updating each render frame
		
	}
}

Members


WidgetSpriteVideo ( Gui gui, string name = 0, int mode = 1 ) #

Constructor. Creates a new sprite that plays video and adds it to the specified GUI.

Arguments

  • Gui gui - GUI, to which the new sprite will belong.
  • string name - Path to a video file.
  • int mode - YUV flag: 1 if conversion to RGB should be performed by the GPU, 0 - if by the CPU.

WidgetSpriteVideo ( string name = 0, int mode = 1 ) #

Constructor. Creates a new sprite that plays video and adds it to the Engine GUI.

Arguments

  • string name - Path to a video file.
  • int mode - YUV flag: 1 if conversion to RGB should be performed by the GPU, 0 - if by the CPU.

void Play ( ) #

Starts playing video.

void Stop ( ) #

Stops playing video. This function saves the playback position so that playing of the file can be resumed from the same point.
