looping_sound

A datum for sounds that need to loop, with a high amount of configurability.

Vars
audio_index	The index of the current song we're playing in the mid_sounds list, only used if in_order is used This is immediately set to 1, so we start the index at 0
chance	Chance per loop to play a mid_sound.
cut_list	If we're using cut_mid, this is the list we cut from
direct	If true, plays directly to provided atoms instead of from them.
each_once	If we should always play each sound once per loop of all sounds. Weights here only really effect order, and could be disgarded
end_sound	(soundfile) The sound played after the main loop has concluded.
end_volume	Override for volume of end sound.
extra_range	The extra range of the sound in tiles, defaults to 0.
falloff_distance	The falloff distance of the sound,
falloff_exponent	How much the sound will be affected by falloff per tile.
ignore_walls	Are we ignoring walls? Defaults to TRUE.
in_order	Whether if the sounds should be played in order or not. Defaults to FALSE.
loop_started	Has the looping started yet?
max_loops	The max amount of loops to run for.
mid_length	The length of time to wait between playing mid_sounds. WARNING: Continuously looping sounds like the microwave, grav gen and fan sounds don't work very well with this, just don't set this if you are doing a continuous loop of machinery.
mid_length_vary	Amount of time to add/take away from the mid length, randomly
mid_sounds	(list or soundfile) Since this can be either a list or a single soundfile you can have random sounds. May contain further lists but must contain a soundfile at the end. In a list, path must have also be assigned a value or it will be assigned 0 and not play.
parent	The source of the sound, or the recipient of the sound.
pressure_affected	Are the sounds affected by pressure? Defaults to TRUE.
skip_starting_sounds	Do we skip the starting sounds?
sound_channel	Sound channel to play on, random if not provided
start_length	How long to wait before starting the main loop after playing start_sound.
start_sound	(soundfile) Played before starting the mid_sounds loop.
start_volume	Override for volume of start sound.
timer_id	The ID of the timer that's used to loop the sounds.
use_reverb	Are the sounds subject to reverb? Defaults to TRUE.
vary	Whether or not the sounds will vary in pitch when played.
volume	Sound output volume.
Procs
get_sound	Returns the sound we should now be playing.
handle_parent_del	A simple proc to handle the deletion of the parent, so that it does not force it to hard-delete.
is_active	A simple proc that lets us know whether the sounds are currently active or not.
on_start	A proc that's there to handle delaying the main sounds if there's a start_sound, and simply starting the sound loop in general.
on_stop	Simple proc that's executed when the looping sound is stopped, so that the `end_sound` can be played, if there's one.
play	The proc that handles actually playing the sound.
set_mid_length	Applies a new mid length to the sound
set_parent	A simple proc to change who our parent is set to, also handling registering and unregistering the QDELETING signals on the parent.
sound_loop	A simple proc handling the looping of the sound itself.
start	The proc to actually kickstart the whole sound sequence. This is what you should call to start the `looping_sound`.
start_sound_loop	The proc that handles starting the actual core sound loop.
stop	The proc to call to stop the sound loop.
stop_current	Stops sound playing on current channel, if specified

If we're using cut_mid, this is the list we cut from

var
direct

If true, plays directly to provided atoms instead of from them.

var
each_once

var
falloff_exponent

var
loop_started

var
mid_length

The length of time to wait between playing mid_sounds. WARNING: Continuously looping sounds like the microwave, grav gen and fan sounds don't work very well with this, just don't set this if you are doing a continuous loop of machinery.

var
mid_length_vary

Amount of time to add/take away from the mid length, randomly

var
mid_sounds

(list or soundfile) Since this can be either a list or a single soundfile you can have random sounds. May contain further lists but must contain a soundfile at the end. In a list, path must have also be assigned a value or it will be assigned 0 and not play.

var
parent
– /atom

The source of the sound, or the recipient of the sound.

var
pressure_affected

Are the sounds affected by pressure? Defaults to TRUE.

var
skip_starting_sounds

Do we skip the starting sounds?

var
sound_channel

Sound channel to play on, random if not provided

var
start_length

How long to wait before starting the main loop after playing start_sound.

var
start_sound

(soundfile) Played before starting the mid_sounds loop.

var
start_volume

Override for volume of start sound.

var

Proc Details

proc
get_sound
(_mid_sounds)

Returns the sound we should now be playing.

proc
handle_parent_del
(/datum/source)

A simple proc to handle the deletion of the parent, so that it does not force it to hard-delete.

proc
is_active
()

A simple proc that lets us know whether the sounds are currently active or not.

proc
on_start
()

A proc that's there to handle delaying the main sounds if there's a start_sound, and simply starting the sound loop in general.

proc
on_stop
()

Simple proc that's executed when the looping sound is stopped, so that the end_sound can be played, if there's one.

proc
play
(soundfile, volume_override)

The proc that handles actually playing the sound.

Arguments:

soundfile - The soundfile we want to play.
volume_override - The volume we want to play the sound at, overriding the volume variable.

proc
set_mid_length
(new_mid)

Applies a new mid length to the sound

proc
set_parent
(new_parent)

A simple proc to change who our parent is set to, also handling registering and unregistering the QDELETING signals on the parent.

proc
sound_loop
(start_time)

A simple proc handling the looping of the sound itself.

Arguments:

start_time - The time at which the mid_sounds started being played (so we know when to stop looping).

proc
start
(on_behalf_of)

The proc to actually kickstart the whole sound sequence. This is what you should call to start the looping_sound.

Arguments:

on_behalf_of - The new object to set as a parent.

proc
start_sound_loop
()

The proc that handles starting the actual core sound loop.

proc
stop
(null_parent)

The proc to call to stop the sound loop.

Arguments:

null_parent - Whether or not we should set the parent to null (useful when destroying the looping_sound itself). Defaults to FALSE.

proc
stop_current
()

Stops sound playing on current channel, if specified
