Unigine::Plugins::FMOD::FMODCore Class

Header: #include <plugins/UnigineFMOD.h>
Notice
This set of functions is available when the FMOD plugin is loaded.

This class is intended to cover the basics / primitives of sound.

FMODCore Class

Members


void close ( ) #

Closes the connection to the output and returns to an uninitialized state without releasing the object.

void release ( ) #

Closes and frees this object and its resources.

void update ( ) #

Updates the FMOD system.

void initCore ( int max_channels, FMODEnums::INIT_FLAGS flags ) #

Initializes the system object and prepares FMOD for playback.

Arguments

  • int max_channels - Maximum number of Channel objects available for playback, also known as virtual channels. Virtual channels will play with minimal overhead, with a subset of 'real' voices that are mixed, and selected based on priority and audibility. Range: [0; 4095]
  • FMODEnums::INIT_FLAGS flags - Initialization flags. More than one mode can be set at once by combining them with the OR operator.

Sound * createSound ( const char * name_of_data, FMODEnums::FMOD_MODE mode ) #

Loads a sound into memory, opens it for streaming or sets it up for callback based sounds.

Arguments

  • const char * name_of_data - Name of the file or URL to open (UTF-8 string) or a pointer to a preloaded sound memory block.
  • FMODEnums::FMOD_MODE mode - Behavior modifier for opening the sound.

Return value

Newly created Sound object.

Sound * createStream ( const char * url ) #

Creates a stream, for example, an internet stream to be used as a radio.

Arguments

  • const char * url - URL of the resource.

Return value

Newly created Sound object.

Channel * playSound ( Sound * sound, ChannelGroup * channel_group, bool paused ) #

Plays a sound on a channel.

Arguments

  • Sound * sound - Sound to play.
  • ChannelGroup * channel_group - Group to output to instead of the master.
  • bool paused - Determines whether to start in the paused state. Start a Channel paused to allow altering attributes without it being audible, then follow it up with a call to ChannelControl::setPaused with paused = False.

Return value

Newly playing channel.

void setListener3DAttributes ( int listener, const Math::Vec3 & position, const Math::Vec3 & up, const Math::Vec3 & forward, const Math::Vec3 & velocity ) #

Sets the 3D attributes of the listener. Vectors must be provided in the correct handedness.

Arguments

  • int listener - Listener index.
  • const Math::Vec3 & position - Position in world space used for panning and attenuation.
  • const Math::Vec3 & up - Upwards orientation, must be of unit length (1.0) and perpendicular to forward.
  • const Math::Vec3 & forward - Forwards orientation, must be of unit length (1.0) and perpendicular to up.
  • const Math::Vec3 & velocity - Velocity in world space used for doppler.

void getListener3DAttributes ( int listener, Math::Vec3 & position, Math::Vec3 & up, Math::Vec3 & forward, Math::Vec3 & velocity ) #

Returns the 3D attributes of the listener.

Arguments

  • int listener - Listener index.
  • Math::Vec3 & position - Position in world space.
  • Math::Vec3 & up - Upwards orientation.
  • Math::Vec3 & forward - Forwards orientation.
  • Math::Vec3 & velocity - Velocity in world space.

Channel * getChannel ( int index ) #

Returns the channel object at the specified index.

Arguments

  • int index - Channel index.

Return value

Channel object.
