Cabal Common Library Doc Music
Contents
Overview
This is the main class for the event driven inflight music for missions and part of the Cabal_Common_Library.
The script handles incoming data from worldScripts to play music in specific situations. OXPs can place or remove their sets fairly simple and a few parameters are handled. The inserted data is associated to the inserting worldScript by ID and the whole group of events can be easily de/activated at every time via .changeStatus(). Additionally a property can be assigned to a specific event, means that different entries can be de/activated by using different properties.
Note: Length, volume and fadeIn/fadeOut in the audio itself are important factors for a smooth transition between musicfiles. For the volume it is adviced to use at least -9 db (peak) to avoid conflicts with spoken inflight messages and digital clipping.
Properties
requestHandlerSet
On startUp created set of handlers (Array) for Cabal_Common_Music.
var a = worldScripts.Cabal_Common_Music.requestHandlerSet; a -> [ [aegis, enter, exit], [alert, red, ... ] ... ]

Adds incoming object to the list and associates the entries to the sending worldScript. Internally every entry gets a group ID, so make sure that the object is extensible and not sealed or frozen.
Properties:
- who
- String. Required. Name of the sending worldScript.
- start
- Boolean. Required. Starting state for the group after insertion.
- aegis
- Object. Allowed members: enter3, exit3.
- alert
- Object. Allowed members: red, yellow1, green1.
- destroyed
- Object. Allowed members: ent.
- exitWS
- Object. Allowed members: inter, goneNova, doNova, standard, any.
- launch
- Object. Allowed members: ent, inter, goneNova, doNova, main, any.
- planet
- Object. Allowed members: ent3, enterMain3, enterSun3, exitMain3, exitSun3.
- scooped
- Object. Allowed members: ent2, fuel4 Added in v1.6.1.
- track
- Object. Allowed members: byName.

1 If other handlers have fired blocked for 10 seconds.
2 The handler is only fired for scripted pods. (Changed in Oolite v1.77)
3 Can collide, because aegis and planet vicinities can be close together.
4 Blocked for 10 seconds when fired.
The above mentioned members are all of type Array and are holding the music related objects.

- String/Number. Either entity.name (String) or entity.radius (Number). Required in destroyed.ent, launch.ent, planet.ent (radius), scooped.ent and track.byName.
- fadeQ
- Number. Optional. Sound as transition between musicfiles. If used must be 1 (will be expanded).
