C# Class flxSharp.flxSharp.FlxSound

This is the universal flixel sound object, used for streaming, music, and sound effects.

Public Methods

Method	Description
FlxSound ( ) : System	The FlxSound constructor gets all the variables initialized, but NOT ready to play a sound yet.
destroy ( ) : void	Clean up memory.
fadeIn ( float seconds ) : void	Call this function to make a sound fade in over a certain time interval (calls `play()` automatically).
fadeOut ( float seconds, bool pauseInstead = false ) : void	Call this function to make this sound fade out over a certain time interval.
getActualVolume ( ) : float	Returns the currently selected "real" volume of the sound (takes fades and proximity into account).
kill ( ) : void
loadEmbedded ( SoundEffect embeddedSound, bool looped = false, bool autoDestroy = false ) : FlxSound	One of two main setup functions for sounds, this function loads a sound from an embedded MP3.
loadStream ( string soundUrl, bool looped = false, bool autoDestroy = false ) : FlxSound	One of two main setup functions for sounds, this function loads a sound from a URL.
pause ( ) : void	Call this function to pause this sound.
play ( bool forceRestart = false ) : void	Call this function to play the sound - also works on paused sounds.
proximity ( float x, float y, FlxObject target, float radius, bool pan = true ) : FlxSound	Call this function if you want this sound's volume to change based on distance from a particular FlxCore object.
resume ( ) : void	Unpause a sound. Only works on sounds that have been paused.
stop ( ) : void	Call this function to stop this sound.
update ( ) : void	Handles fade out, fade in, panning, proximity, and amplitude operations each frame.

Protected Methods

Method	Description
createSound ( ) : void	An internal function for clearing all the variables used by sounds.

Private Methods

Method	Description
updateTransform ( ) : void	Call after adjusting the volume to update the sound channel's settings.

Method Details

FlxSound() public method

The FlxSound constructor gets all the variables initialized, but NOT ready to play a sound yet.

public FlxSound ( ) : System
return	System

createSound() protected method

An internal function for clearing all the variables used by sounds.

protected createSound ( ) : void
return	void

destroy() public method

Clean up memory.

public destroy ( ) : void
return	void

fadeIn() public method

Call this function to make a sound fade in over a certain time interval (calls play() automatically).

public fadeIn ( float seconds ) : void
seconds	float	The amount of time the fade-in operation should take.
return	void

fadeOut() public method

Call this function to make this sound fade out over a certain time interval.

public fadeOut ( float seconds, bool pauseInstead = false ) : void
seconds	float	The amount of time the fade out operation should take.
pauseInstead	bool	Tells the sound to pause on fadeout, instead of stopping.
return	void

getActualVolume() public method

Returns the currently selected "real" volume of the sound (takes fades and proximity into account).

public getActualVolume ( ) : float
return	float

kill() public method

public kill ( ) : void
return	void

loadEmbedded() public method

One of two main setup functions for sounds, this function loads a sound from an embedded MP3.

public loadEmbedded ( SoundEffect embeddedSound, bool looped = false, bool autoDestroy = false ) : FlxSound
embeddedSound	Microsoft.Xna.Framework.Audio.SoundEffect	An embedded Class object representing an MP3 file.
looped	bool	Whether or not this sound should loop endlessly.
autoDestroy	bool	Whether or not this `FlxSound` instance should be destroyed when the sound finishes playing. Default value is false, but FlxG.play() and FlxG.stream() will set it to true by default.
return	FlxSound

loadStream() public method

One of two main setup functions for sounds, this function loads a sound from a URL.

public loadStream ( string soundUrl, bool looped = false, bool autoDestroy = false ) : FlxSound
soundUrl	string	A string representing the URL of the MP3 file you want to play.
looped	bool	Whether or not this sound should loop endlessly.
autoDestroy	bool	Whether or not this `FlxSound` instance should be destroyed when the sound finishes playing. Default value is false, but FlxG.play() and FlxG.stream() will set it to true by default.
return	FlxSound

pause() public method

Call this function to pause this sound.

public pause ( ) : void
return	void

play() public method

Call this function to play the sound - also works on paused sounds.

public play ( bool forceRestart = false ) : void
forceRestart	bool	Whether to start the sound over or not. Default value is false, meaning if the sound is already playing or was paused when you call `play()`, it will continue playing from its current position, NOT start again from the beginning.
return	void

proximity() public method

Call this function if you want this sound's volume to change based on distance from a particular FlxCore object.

public proximity ( float x, float y, FlxObject target, float radius, bool pan = true ) : FlxSound
x	float	The X position of the sound.
y	float	The Y position of the sound.
target	FlxObject	The object you want to track.
radius	float	The maximum distance this sound can travel.
pan	bool	Whether the sound should pan in addition to the volume changes (default: true).
return	FlxSound

resume() public method

Unpause a sound. Only works on sounds that have been paused.

public resume ( ) : void
return	void

stop() public method

Call this function to stop this sound.

public stop ( ) : void
return	void

update() public method

Handles fade out, fade in, panning, proximity, and amplitude operations each frame.

public update ( ) : void
return	void
