Demoniak3D/LUA Api: Playlist

The HYP_Playlist library provides several features for managing soundtracks (adding / suppressing / audio track play in the same way as the playlists of winamp ;) ).
HYP_Playlist.Create
HYP_Playlist.Destroy
HYP_Playlist.AddTrack
HYP_Playlist.RemoveTrack
HYP_Playlist.SetCurrentTrack
HYP_Playlist.GetCurrentTrackId
HYP_Playlist.GetCurrentTrackName
HYP_Playlist.Play
HYP_Playlist.Stop
HYP_Playlist.SetOptions

Create

Create allows to create a new playlist.
Syntax
id = HYP_Playlist.Create( name );
  • name - [STR127] - name of the playlist.
  • id - [INTEGER] - identifier of the newly created playlist.

Destroy

Destroy allows to destroy a playlist.
Syntax
HYP_Playlist.Destroy( name|id );
  • name - [STR127] - name of the playlist.
  • id - [INTEGER] - identifier of the playlist.

AddTrack

AddTrack allows to add an audio track to a playlist.
Syntax
id_st = HYP_Playlist.AddTrack( name|id, soundtrack_name|soundtrack_id  );
  • name - [STR127] - name of the playlist.
  • id - [INTEGER] - identifier of the playlist.
  • soundtrack_name - [STR127] - name of the soudtrack. This name may also be the relative path to the audio file.
  • soundtrack_id - [INTEGER] - identifier of the soudtrack. This identifier may have been changed wether in the XML code or by the HYP_Sound.Load() function.
  • id_st - [INTEGER] -identifier of the newly added soudtrack.
Example
id_pl = HYP_Playlist.Create( "myCoolPlaylist" );
id_st1 = HYP_Playlist.AddTrack( id_pl, "data/mp3/first.mp3"  );
id_st2 = HYP_Playlist.AddTrack( id_pl, "data/mp3/second.mp3"  );
HYP_Playlist.Play( id_pl );

RemoveTrack

RemoveTrack to remove an audio track from a playlist.
Syntax
HYP_Playlist.RemoveTrack( name|id, soundtrack_name|soundtrack_id  );
  • name - [STR127] - name of the playlist.
  • id - [INTEGER] - identifier of the playlist.
  • soundtrack_name - [STR127] - name of the soudtrack.
  • soundtrack_id - [INTEGER] - identifier of the soudtrack.

SetCurrentTrack

SetCurrentTrack allows to change audio track for playing.
Syntax
HYP_Playlist.SetCurrentTrack( name|id, soundtrack_name|soundtrack_id  );
  • name - [STR127] - name of the playlist.
  • id - [INTEGER] - identifier of the playlist.
  • soundtrack_name - [STR127] - name of the soudtrack.
  • soundtrack_id - [INTEGER] - identifier of the soudtrack.

GetCurrentTrackId

GetCurrentTrackId allows to get the identifier of the current playing audio track.
Syntax
id_st = HYP_Playlist.GetCurrentTrackId( name|id );
  • name - [STR127] - name of the playlist.
  • id - [INTEGER] - identifier of the playlist.
  • id_st - [INTEGER] - identifier of the soudtrack.

GetCurrentTrackName

GetCurrentTrackName allows to get the name of the current playing audio track.
Syntax
name_st = HYP_Playlist.GetCurrentTrackName( name|id );
  • name - [STR127] - name of the playlist.
  • id - [INTEGER] - identifier of the playlist.
  • name_st - [INTEGER] - name of the soudtrack.

Play

Play allows to start playing audio track from the playlist.
Syntax
HYP_Playlist.Play( name|id );
  • name - [STR127] - name of the playlist.
  • id - [INTEGER] - identifier of the playlist.

Stop

Stop allows to stop playing audio track from the playlist.
Syntax
HYP_Playlist.Stop( name|id );
  • name - [STR127] - name of the playlist.
  • id - [INTEGER] - identifier of the playlist.

SetOptions

SetOptions allows to change the working mode of the playlist.
Syntax
HYP_Playlist.SetOptions( name|id, options );
  • name - [STR127] - name of the playlist.
  • id - [INTEGER] - identifier of the playlist.
  • options - [INTEGER] - options de la playlist:
    • PLAYLIST_TRACKS_MANAGEMENT_OFF = 1
    • PLAYLIST_TRACKS_MANAGEMENT_ON = 2
    • PLAYLIST_LOOP_ON = 3
    • PLAYLIST_LOOP_OFF = 4
    • PLAYLIST_DISPLAY_CUR_TRACK_NAME_ON = 6
    • PLAYLIST_DISPLAY_CUR_TRACK_NAME_OFF = 7
    • PLAYLIST_ENABLED = 8
    • PLAYLIST_DISABLED = 9
    These options are "problem-free" except for PLAYLIST_TRACKS_MANAGEMENT_ON/PLAYLIST_TRACKS_MANAGEMENT_OFF. LAYLIST_TRACKS_MANAGEMENT_ON let Hyperion manage the different audio track transitions. It is the default value. PLAYLIST_TRACKS_MANAGEMENT_OFF requires to use afterwards HYP_Sound.IsTrackFinished() and other functions from the HYP_Sound lib to manage oneself the audio file playing.
