Unigine::Sound Class

Members

---

virtual ~Sound ()

Virtual destructor.

static Sound * get ()

Returns a pointer to the existing sound.

Return value

Pointer to the existing sound.

virtual void setEnabled (int enable) const =0

Enables or disables the sound.

Arguments

• int enable - 1 to enable the sound, 0 to disable it.

virtual int isEnabled () const =0

Returns a value indicating if the sound is enabled.

Return value

Returns 1 if the sound is enabled; otherwise, 0.

virtual void setVolume (float volume) const =0

Sets the sound volume in range [0;1]. The default is 1 that means maximum volume.

Arguments

• float volume - Sound volume. 0 means muted sound, 1 means maximum volume.

virtual float getVolume () const =0

Returns the current sound volume.

Return value

Sound volume. 0 means muted sound, 1 means maximum volume.

virtual void setSourceVolume (int source, float volume) const =0

Sets the volume of the specified sound channel.

Arguments

• int source - Number of the sound channel (from 0 to 31).
• float volume - Channel volume. The provided value is saturated within [0;1] range, where 0 means muted sound and 1 is the maximum volume.

virtual float getSourceVolume (int source) const =0

Returns the current volume of the specified sound channel.

Arguments

• int source - Number of the sound channel (from 0 to 31).

Return value

Volume of the specified sound channel. The returning value is in range [0;1], where 0 means muted sound and 1 is the maximum volume.

virtual void renderWorld (int force) const =0

Forces update of the sound system: all sound settings will be applied at once (such as play, stop events and change of parameters). A sound system has its own fixed frame rate (30 fps), while a script update rate can be much higher, which sometimes cause commands being skipped, unless a forced update is used.

Arguments

• int force - 1 to force update of the sound system; otherwise, 0.

virtual int loadWorld (const XmlPtr & xml) const =0

Loads a sound state from the Xml. The sound state includes such settings as the volume, velocity, adaptation, Doppler factor, time scale and number of sound sources and their volumes.

Arguments

• const XmlPtr & xml - Xml smart pointer.

Return value

Returns 1 if the the sound state is loaded successfully; otherwise, 0 is returned.

virtual int saveWorld (const XmlPtr & xml) const =0

Saves a sound state into the Xml. The sound state includes such settings as the volume, velocity, adaptation, Doppler factor, time scale and number of sound sources and their volumes.

Arguments

• const XmlPtr & xml - Xml smart pointer.

Return value

Returns 1 if the sound state is saved successfully; otherwise, 0.

virtual int saveState (const StreamPtr & stream) const =0

Saves a sound state into the stream. The sound state includes such settings as the volume, velocity, adaptation, Doppler factor, time scale and number of sound sources and their volumes.

Arguments

• const StreamPtr & stream - Stream smart pointer.

Return value

Returns 1 if the sound state is saved successfully; otherwise, 0.

virtual int restoreState (const StreamPtr & stream) const =0

Restores a sound state from the stream. The sound state includes such settings as the volume, velocity, adaptation, Doppler factor, time scale and number of sound sources and their volumes.

Arguments

• const StreamPtr & stream - Stream smart pointer.

Return value

Returns 1 if the sound state is restored successfully; otherwise, 0 is returned.
