Oolite JavaScript Reference: SoundSource

Prototype: Object
Subtypes: none

A SoundSource is an abstract object that can play a sound. A given SoundSource can only be playing one sound at a particular time.

Sound Expressions

Several SoundSource properties and methods can take either Sound object, or a string representing a file name or a customsounds.plist key.

Constructor

new SoundSource : SoundSource

Creates a new SoundSource that can be altered. e.g.:

var mySound = new SoundSource;
mySound.sound = "trumblesqueal.ogg";
mySound.loop = true;
mySound.play();

Properties

isPlaying

isPlaying : Boolean (read-only)

true if the sound is currently playing, false otherwise.

loop

loop : Boolean (read/write)

true if the sound source should loop its sound, false otherwise. Changing this while a sound is playing does not affect the currently-playing sound; it only takes effect when the sound source starts playing.

See Also: repeatCount

position

This property was added in Oolite test release 1.79.

position : Vector (read/write)

The position of the sound source relative to the listener. The listener is always positioned at the origin facing along the Z axis. Therefore if the sound relates to something outside the spaceship, it will need to be positioned relatively to the player.

positional

This property was added in Oolite test release 1.79.

positional : Boolean (read/write)

Whether the SoundSource is positional at all. Non-positional sound sources are "positioned" at the origin.

Note that a SoundSource playing a sound with stereo information built-in is effectively non-positional.

repeatCount

repeatCount : Integer (read/write)

The number of times the sound should repeat, if loop is false, ranging from 1 to 100. Unlike loop, this can usefully be changed while the sound is playing, and repeatCount will be decremented each time the sound is repeated.

See Also: loop

sound

sound : soundExpression (read/write)

The sound to be played by this sound source. You can assign either a Sound or a string to this property, but when you read it it will always be a Sound object (or null).

volume

This property was added in Oolite test release 1.79.

volume : Number (read/write)

The relative volume of the sound source, between 0.0 and 1.0, with 1.0 being the loudest possible and the default. This is further modified of course by the global volume set by the player in their preferences.

Methods

play

function play([count : Integer])

Start playing sound. If count is specified, repeatCount is set to count first. If the sound source is currently playing a sound, it is stopped.

See Also: playOrRepeat(), playSound()

playOrRepeat

function playOrRepeat()

If a sound is not playing, starts playing. If a sound is playing and is not looping, increases repeatCount by one.

See Also: play()

playSound

function playSound(sound : soundExpression [, count : Integer])

Set sound (and, optionally, repeatCount) and start playing.

See Also: play()

stop

function stop()

Stop playing sound.
