Cabal Common Library Doc Music

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, ... ] ... ]

Functions

Adds incoming object to the list and associates the entries to the sending worldScript. Internally every entry gets a group ID, so don't pass non-writable, sealed or frozen objects.

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.

track

Object. Allowed members: byName.

Returns

Boolean

True on success, false on failure.

¹ If other handlers have fired blocked for 10 seconds.
² The handler is only fired for scripted pods.
³ Can collide, because aegis and planet vicinities can be close together.

The above mentioned members are all of type Array and are holding the music related objects. See Structure for a overview.

The objects that are holding the music itself have a set of available properties as well.

dist

Number. Min. distance to entity. Required in track.byName.

ent

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).

music

String. Required. Filename with fileextension.

prop

String. Optional. Name of worldScript property to be checked.
