Namespace Hierarchy
The DirectX .NET classes reside in the Sunlight.DirectX namespace. This namespace is further partitioned into Graphics, Input and SoundMusic namespaces.
Sunlight.DirectX
The Sunlight.DirectX namespace contains the following class:
- DirectXException. This class extends System.Exception to handle return values from DirectX methods.
Sunlight.DirectX.Graphics
The Sunlight.DirectX.Graphics namespace contains the following classes:
- Direct3D. This class wraps an IDirect3D8 object. An application typically does not use this class directly.
- Device. This class wraps an IDirect3DDevice8 object. This class handles device initialisation, mode switching, lost devices and page flipping.
- Texture. This class wraps an IDirect3DTexture8 object. This class represents an unfiltered, managed DirectX Graphics texture.
- Sprite. This class represents a rectangular object on the screen, with position and size.
- SpriteManager. This class handles the display of Sprite objects on a Device. It holds an IDirect3DVertexBuffer8 object to perform this task.
- GraphicsForm. This class extends System.Windows.Forms.Form to allow the use of the DirectX Graphics classes. It provides exception handling, idle-time events and device recovery.
Sunlight.DirectX.Input
The Sunlight.DirectX.Input namespace contains the following classes:
- DirectInput. This class wraps an IDirectInput8 object. This class handles all input events, configuration, device acquisition and enumeration.
- ActionMap. This class represents a collection of entries in a DirectInput action map.
Sunlight.DirectX.SoundMusic
The Sunlight.DirectX.SoundMusic namespace contains the following classes:
- DirectMusic. This class wraps an IDirectMusicPerformance8 object and an IDirectMusicLoader8 object. This class handles performance initialisation for DirectMusic.
- Sound. This class wraps an IDirectMusicSegment8 object. This class handles sound effect loading and playback.
- BackgroundSound. This class extends Sound to allow the use of MIDI music and DirectShow-compatible audio tracks (Windows Media Audio, MP3). It provides capabilities for detecting the end of tracks, and for stopping the music while the application is inactive.
