Soundpacks

A soundpack can be installed in the data/sound directory. It has to be a subdirectory that contains at least a file named soundpack.txt. It can include any number of json files which add any number of sound_effect or playlists.

soundpack.txt format

The soundpack.txt file format needs 2 values, a NAME and a VIEW. The NAME value should be unique. The VIEW value will be shown in the options menu. Every line starting with a # is a comment line.

#Basic provided soundpack
#Name of the soundpack
NAME: basic
#Viewing name of the soundpack
VIEW: Basic

JSON format

Sound effects

Sound effects can be included with a format like this:

[
  {
    "type": "sound_effect",
    "id": "menu_move",
    "volume": 100,
    "files": [ "nenadsimic_menu_selection_click.wav" ]
  },
  {
    "type": "sound_effect",
    "id": "fire_gun",
    "volume": 90,
    "variant": "bio_laser_gun",
    "season": "summer",
    "files": [ "guns/energy_generic/weapon_fire_laser.ogg" ]
  },
  {
    "type": "sound_effect",
    "id": "open_door",
    "volume": 75,
    "variant": "t_door_c",
    "season": "summer",
    "is_indoors": true,
    "is_night": false,
    "files": [ "indoors/open_door_daytime.ogg" ]
  }
]

Each sound effect is identified by an id, a variant, and a season. If a sound effect is played with a variant that does not exist in the json files, but a variant "default" exists, then the "default" variant is played instead. The file name of the sound effect is relative to the soundpack directory, so if the file name is set to "sfx.wav" and your soundpack is in data/sound/mypack, the file must be placed at data/sound/mypack/sfx.wav.

Adding variety

Several optional fields can be defined to target specific situations:

Field Purpose
variant Defines a specific subset of the id's sound group. (ex: "id": "environment", "variant": "WEATHER_DRIZZLE")
season If defined, the sound will only play on the specified season. (possible values are spring, summer, autumn, and winter).
is_indoors If defined, the sound will only play if the player is indoors/outdoors when true/false.
is_night If defined, the sound will only play if the current time is night/day when true/false.

If multiple files are defined for the sound effect, one will be chosen at random when the sound is played.

The volume key may range from 0-100.

Cataclysm has its own set of user-controllable volumes that will additionally affect the sound. These range from 0-128, and the default is 100. This means that at default volume, any sound that Cataclysm plays will default to playing at about 78% of the maximum; if you are working on sounds in an external audio editor, expect Cataclysm at default volume settings to play that sound file back quieter than your editor does.

Preloading SFX

Sound effects can be included for preloading with a format like this:

[
  {
    "type": "sound_effect_preload",
    "preload": [
      { "id": "environment", "variant": "thunder_near", "season": "spring", "is_night": false },
      { "id": "environment" }
    ]
  }
]

Playlists

A playlist can be included with a format like this:

[
  {
    "type": "playlist",
    "playlists": [
      {
        "id": "title",
        "shuffle": false,
        "files": [ { "file": "Dark_Days_Ahead_demo_2.wav", "volume": 100 }, { "file": "cataclysmthemeREV6.wav", "volume": 90 } ]
      }
    ]
  },
  {
    "type": "playlist",
    "playlists": [
      {
        "id": "mp3",
        "shuffle": false,
        "files": [ { "file": "Dark_Days_Ahead_demo_2.wav", "volume": 100 }, { "file": "cataclysmthemeREV6.wav", "volume": 90 } ]
      }
    ]
  }
]

Playlists are similar to sound effects in that they are each identified by an id. However, their similarities end there. Playlists cannot overlap each other unlike sound effects, they do not have optional fields such as variant and season, and the exact formatting for the files field is slightly different.

Playlists are governed mainly by their id, which dictate in which situation a given playlist will be activated. Different situations trigger different ids, and if more than one ids are active at the same time, then the conflict is resolved by a priority model. Basically, each music id are given a hard-coded priority, where ids with higher priority takes precedent.

Playlists List

A full list and priority of playlist ids is given in the following.

  • mp3 This id is assigned with the highest priority value. Playlists that has this id will be activated when the player hears music with no sound, usually via a mp3 player or its variant.

  • instrument This id is assigned with the second highest priority value. Playlists that has this id will be activated when the player plays any musical instrument.

  • sound This id is assigned with the third highest priority value. Playlists that has this id will be activated when the player hears music with some sound, usually via a stereo or an i-pad.

  • title This id is assigned with the lowest priority value. It will be played only when all other playlists are inactive.

JSON Format Sound Effects List

A full list of sound effect IDs and variants is given in the following. Each line in the list has the following format:

id variant1|variant2

Where id describes the ID of the sound effect, and a list of variants separated by | follows. When the variants are omitted, the variant "default" is assumed. Where the variants do not represent literal strings, but variables, they will be enclosed in < >. For instance, <furniture> is a placeholder for any valid furniture ID (as in the furniture definition JSON).

Vehicle

Engines and other parts in action. The defaults are executed when a specific option is not defined.

  • engine_start <vehicle_part>: specific engine start (ID of any engine/motor/steam_engine/paddle/oar/sail/etc.)

  • engine_start combustion|electric|muscle|wind: default engine starts groups

  • engine_stop <vehicle_part>: specific engine stop (ID of any engine/motor/steam_engine/paddle/oar/sail/etc.)

  • engine_stop combustion|electric|muscle|wind: default engine stop groups

    Internal engine sound is dynamically pitch shifted depending on vehicle speed. It is an ambient looped sound with a dedicated channel.

  • engine_working_internal <vehicle_part>: sound of engine working heard inside vehicle

  • engine_working_internal combustion|electric|muscle|wind: default engine working (inside) groups

    External engine sound volume and pan is dynamically shifted depending on distance and angle to vehicle. Volume heard at given distance is linked to engine's noise_factor and stress to the engine (see vehicle::noise_and_smoke()). It is an ambient looped sound with its own dedicated channel. This is a single-channel solution that picks loudest heard vehicle (TODO: multi-channel for every heard vehicle). There is no pitch shift here (may be introduced when need for it emerges).

  • engine_working_external <vehicle_part>: sound of engine working heard outside vehicle

  • engine_working_external combustion|electric|muscle|wind: default engine working (outside) groups

    gear_up/gear_down is done automatically by pitch manipulation. Gear shift is dependent on max safe speed, and works on the assumption that there are 6 forward gears, gear 0 is neutral, and gear -1 is reverse.

  • vehicle gear_shift

  • vehicle engine_backfire|engine_bangs_start|fault_immobiliser_beep|engine_single_click_fail|engine_multi_click_fail|engine_stutter_fail|engine_clanking_fail
