Cabal Common Library Doc Briefing

From Elite Wiki
Revision as of 12:58, 19 August 2011 by Svengali (talk | contribs) (added new methods for background and overlay pics)

Overview

This is the main class for the briefing with its members.

The script handles incoming data from worldScripts to make missionscreens a bit more interesting with time based animations of the displayed model. Scripts can pass the data easily and everything else is performed within the briefing script.

worldScripts.Cabal_Common_Briefing.startBriefing(obj);


A second approach is possible by instantiating a copy of the underlaying API, e.g.

this.helper = new Cabal_Common_ScreenFCB();

But scripts are then responsible to remove the framecallbacks on their own with the method provided by the API!


Functions

startBriefing()

worldScripts.Cabal_Common_Briefing.startBriefing = function( obj )

Calling this method starts the handling. The passed obj must hold a few parameters to define the actions.

Parameters:

obj
Object.

Returns:

nothing


Properties of obj:

absolutePos
Array. Optional. E.g. [10,12,540].
background
String. Optional. Filename with extension.
briefing
Array. Required. Action commands.
callback
String. Required. WorldScript identifier.
callbackc
String. Optional. Mission choice.
callbackf
String. Required. Callback function.
capture
Boolean. If true only a new briefing, callback and callbackf gets established.
cornerPos
Array. Optional. Movement to one corner. E.g. [0.33,1,1,1.3]
getOri
String. Optional. script_info keyname that holds orientation, e.g. "1,0,0,0".
getPos

ori
Array. Optional. Orientation. E.g. [1,0,0,0].

A short example:

var obj = {
role:"trader",
ori:[1,0,0,0],
briefing:[
[3,"mVelo",[0,-1,3,-1.005,0,0,1,0,0.85]],
[17,"stopVelo",[0,-1]]
],
callback:this.name,
callbackf:"choiceEval"

};
worldScripts.Cabal_Common_Briefing.startBriefing(obj);


obj.briefing

The briefing array contains the timebased actions. A entry contains at least two elements:

Time
Number. Based on a interval of 0.25 sec.
Action
String. Specifier for the action. Most actions will need additional parameter.

Short overview about the actions:

  • bgzoom - Zooms background image in and out. See fcbZoomBackground().
  • bind - Sticks two subents together. See fcbSetBinding().
  • check - Useful for developers to see how many framecallbacks are invoked. See fcbCheckAll().
  • continue - Enables checkpoints if specific points are reached.
  • face - Rotate entity to face another entity. See fcbFace().
  • kill - Stops briefing and clears all fcbs. See fcbRemoveAll().
  • mes - Add a message.
  • mSpeed - Velocity based on vectorForward. See fcbModelSpeed().
  • mVelo - Velocity vectorUp, Right and Forward. See fcbModelVelo().
  • prop - Set property, e.g. fuel. See fcbSetProp().
  • reback - Set background image. See reBackground(). (New in v1.4.5)
  • reori - Set orientation. See reOrient().
  • reover - Set overlay image. See reOverlay(). (New in v1.4.5)
  • repos - Set position. See rePosition().
  • retex - Set materials/shaders. See reTexture().
  • rot - Rotate X,Y,Z. See fcbRotation().
  • stopSound - Stop briefing sound.
  • stopVelo - Stop velocity. See stopVelo().
  • turn - Rotate vectorUp, Right and Forward and velocity. See fcbFlight().
  • walk - Subtract Z-position, biased Y. See fcbWalk().
  • zoom - Multiplied position. See fcbZoom().
