Detailed Description

The RainDMPerf8 class is created in AllAudio as pPerfMusic and pPerfSound. All funcion calls of the RainDMPerf8 class can be used by, and are recomended to be used by, the AllAudio class. Most projects will have no reason to create their own RainDMPerf8 class. Volume control for sounds is done per RainDMPerf8 class, all DirectMusic Segments are controled by this class. Although the pPerfMusic variable has access to an array of Segments, all but the zeroth element will not be acessable, and may cause instabilty if created.

Member Function Documentation

HRESULT RainDMPerf8::Initialize (  char **    p_szSongNameArray, UINT    uMaxSizeOfArray, IDirectMusicLoader8 **    ppLoader )

Creates an array of DirectMusic Segements and loads a file into each one. The pPerfMusic object should only have one Segment at a time.

HRESULT RainDMPerf8::PlayTrack (  UINT    uIdx, DWORD    dwRepeats )

Parameters: dwRepeats:  Use the REPEAT_FOREVER flag to play track until RainDMPerf8::Stop(); is called. Plays a sound file from a DirectMusic Segment in the array based off the uIdx paramiter. Make sure to initialze the Segment prior to calling this function by either the RainPerf8::Initialize function by setting it specifically with RainPerf8::SetTrackFile.

HRESULT RainDMPerf8::SetTrackFile (  char *    szFile, UINT    uIdx, IDirectMusicLoader8 **    ppLoader )

loads a file into one DirectMusic Segment in the array. Isn't noramally needed as all Segments are initialized in the RainPerf8::Initialize function.

HRESULT RainDMPerf8::Stop (  void    )

Stops all playing Segments.
