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:
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
}
}

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.Last update:
