Represents a sound which is currently played.
The sound can be stopped, its volume or pan changed, effects added/removed and similar using this interface. Creating sounds is done using ISoundEngine::play2D() or ISoundEngine::play3D(). More informations about the source of a sound can be obtained from the ISoundSource interface.
| virtual bool irrklang::ISound::getIsPaused | ( | ) | [pure virtual] |
returns if the sound is paused
| virtual ik_f32 irrklang::ISound::getMaxDistance | ( | ) | [pure virtual] |
Returns the maximal distance if this is a 3D sound.
See setMaxDistance() for details.
| virtual ik_f32 irrklang::ISound::getMinDistance | ( | ) | [pure virtual] |
Returns the minimal distance if this is a 3D sound.
See setMinDistance() for details.
| virtual ik_f32 irrklang::ISound::getPan | ( | ) | [pure virtual] |
returns the pan of the sound. Takes a value between -1 and 1, 0 is center.
| virtual ik_f32 irrklang::ISound::getPlaybackSpeed | ( | ) | [pure virtual] |
Returns the playback speed set by setPlaybackSpeed(). Default: 1.0f.
See setPlaybackSpeed() for details
| virtual ik_u32 irrklang::ISound::getPlayLength | ( | ) | [pure virtual] |
returns the play length of the sound in milliseconds.
Returns -1 if not known for this sound for example because its decoder does not support length reporting or it is a file stream of unknown size. Note: You can also use ISoundSource::getPlayLength() to get the length of a sound without actually needing to play it.
| virtual ik_u32 irrklang::ISound::getPlayPosition | ( | ) | [pure virtual] |
returns the current play position of the sound in milliseconds.
| virtual vec3df irrklang::ISound::getPosition | ( | ) | [pure virtual] |
returns the position of the sound in 3d space
| virtual ISoundEffectControl* irrklang::ISound::getSoundEffectControl | ( | ) | [pure virtual] |
Returns the sound effect control interface for this sound.
Sound effects such as Chorus, Distorsions, Echo, Reverb and similar can be controlled using this. The interface pointer is only valid as long as the ISound pointer is valid. If the ISound pointer gets dropped (IVirtualRefCounted::drop()), the ISoundEffects may not be used any more.
| virtual ISoundSource* irrklang::ISound::getSoundSource | ( | ) | [pure virtual] |
returns source of the sound which stores the filename and other informations about that sound
| virtual vec3df irrklang::ISound::getVelocity | ( | ) | [pure virtual] |
returns the velocity of the sound in 3d space, needed for Doppler effects.
To use doppler effects use ISound::setVelocity to set a sounds velocity, ISoundEngine::setListenerPosition() to set the listeners velocity and ISoundEngine::setDopplerEffectParameters() to adjust two parameters influencing the doppler effects intensity.
| virtual ik_f32 irrklang::ISound::getVolume | ( | ) | [pure virtual] |
returns volume of the sound, a value between 0 (mute) and 1 (full volume).
(this volume gets multiplied with the master volume of the sound engine and other parameters like distance to listener when played as 3d sound)
| virtual bool irrklang::ISound::isFinished | ( | ) | [pure virtual] |
returns if the sound has finished playing.
Don't mix this up with isPaused(). isFinished() returns if the sound has been finished playing. If it has, is maybe already have been removed from the playing list of the sound engine and calls to any other of the methods of ISound will not have any result. If you call stop() to a playing sound will result that this function will return true when invoked.
| virtual bool irrklang::ISound::isLooped | ( | ) | [pure virtual] |
returns if the sound has been started to play looped
| virtual void irrklang::ISound::setIsLooped | ( | bool | looped | ) | [pure virtual] |
changes the loop mode of the sound.
If the sound is playing looped and it is changed to not-looped, then it will stop playing after the loop has finished. If it is not looped and changed to looped, the sound will start repeating to be played when it reaches its end. Invoking this method will not have an effect when the sound already has stopped.
| virtual void irrklang::ISound::setIsPaused | ( | bool | paused = true |
) | [pure virtual] |
returns if the sound is paused
| virtual void irrklang::ISound::setMaxDistance | ( | ik_f32 | max | ) | [pure virtual] |
Sets the maximal distance if this is a 3D sound.
Changing this value is usually not necessary. Use setMinDistance() instead. Don't change this value if you don't know what you are doing: This value causes the sound to stop attenuating after it reaches the max distance. Most people think that this sets the volume of the sound to 0 after this distance, but this is not true. Only change the minimal distance (using for example setMinDistance()) to influence this. The maximum distance for a sound source is the distance beyond which the sound does not get any quieter. The default minimum distance is 1, the default max distance is a huge number like 1000000000.0f.
| virtual void irrklang::ISound::setMinDistance | ( | ik_f32 | min | ) | [pure virtual] |
Sets the minimal distance if this is a 3D sound.
Changes the distance at which the 3D sound stops getting louder. This works like this: As a listener approaches a 3D sound source, the sound gets louder. Past a certain point, it is not reasonable for the volume to continue to increase. Either the maximum (zero) has been reached, or the nature of the sound source imposes a logical limit. This is the minimum distance for the sound source. Similarly, the maximum distance for a sound source is the distance beyond which the sound does not get any quieter. The default minimum distance is 1, the default max distance is a huge number like 1000000000.0f.
| virtual void irrklang::ISound::setPan | ( | ik_f32 | pan | ) | [pure virtual] |
sets the pan of the sound. Takes a value between -1 and 1, 0 is center.
| virtual bool irrklang::ISound::setPlaybackSpeed | ( | ik_f32 | speed = 1.0f |
) | [pure virtual] |
Sets the playback speed (frequency) of the sound.
Plays the sound at a higher or lower speed, increasing or decreasing its frequency which makes it sound lower or higher. Note that this feature is not available on all sound output drivers (it is on the DirectSound drivers at least), and it does not work together with the 'enableSoundEffects' parameter of ISoundEngine::play2D and ISoundEngine::play3D when using DirectSound.
| speed | Factor of the speed increase or decrease. 2 is twice as fast, 0.5 is only half as fast. The default is 1.0. |
| virtual bool irrklang::ISound::setPlayPosition | ( | ik_u32 | pos | ) | [pure virtual] |
sets the current play position of the sound in milliseconds.
| pos | Position in milliseconds. Must be between 0 and the value returned by getPlayPosition(). |
| virtual void irrklang::ISound::setPosition | ( | vec3df | position | ) | [pure virtual] |
sets the position of the sound in 3d space
| virtual void irrklang::ISound::setSoundStopEventReceiver | ( | ISoundStopEventReceiver * | reciever, | |
| void * | userData = 0 | |||
| ) | [pure virtual] |
Sets the sound stop event receiver, an interface which gets called if a sound has finished playing.
This event is guaranteed to be called when the sound or sound stream is finished, either because the sound reached its playback end, its sound source was removed, ISoundEngine::stopAllSounds() has been called or the whole engine was deleted. There is an example on how to use events in irrklang at Using Sound Events .
| receiver | Interface to a user implementation of the sound receiver. This interface should be as long valid as the sound exists or another stop event receiver is set. Set this to null to set no sound stop event receiver. | |
| userData,: | A iser data pointer, can be null. |
| virtual void irrklang::ISound::setVelocity | ( | vec3df | vel | ) | [pure virtual] |
sets the position of the sound in 3d space, needed for Doppler effects.
To use doppler effects use ISound::setVelocity to set a sounds velocity, ISoundEngine::setListenerPosition() to set the listeners velocity and ISoundEngine::setDopplerEffectParameters() to adjust two parameters influencing the doppler effects intensity.
| virtual void irrklang::ISound::setVolume | ( | ik_f32 | volume | ) | [pure virtual] |
sets the volume of the sound, a value between 0 (mute) and 1 (full volume).
This volume gets multiplied with the master volume of the sound engine and other parameters like distance to listener when played as 3d sound.
| virtual void irrklang::ISound::stop | ( | ) | [pure virtual] |
Will stop the sound and free its resources.
If you just want to pause the sound, use setIsPaused(). After calling stop(), isFinished() will usually return true. Be sure to also call ->drop() once you are done.
