X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=ce574d59f536512931fa27a439d001863219f40b;p=flightgear.git

The following changes were made to flightgear-0.7.5 code to implement the follow
ing features:

a) ADA Flight model - ADA.cxx, ADA.hxx, flight.hxx
b) Fighter a/c HUD       - flight.hxx, hud.hxx, hud.cxx, cockpit.cxx, hud_ladr.c
xx, hud_card.cxx
c) 3-window display      - options.hxx, options.cxx, viewer.cxx
d) Moving objects (ship) - main.cxx
e) Patches               - main.cxx

ADA.cxx, ADA.hxx
--------------------------
Interface to the external ADA flight dynamics package.

flight.hxx
----------
Included prototypes for accepting additional data fron the External flight
model for fighter aircraft HUD

Hud.hxx
-------
Included prototypes for accepting additional data for fighter HUD from Exernal F
light model.
Defined FIGHTER_HUD pre-processor directive to enable compilation of fighter hud
 code.

hud.cxx, cockpit.cxx, hud_ladr.cxx, hud_card.cxx
---------------------------------------
Included code to initialise additional reticles/text for fighter HUD which is co
nditionally
compiled if FIGHTER_HUD is defined.

options.hxx
-----------
Added window_offset, and function to retrieve its value for 3 windows

options.cxx
-----------
Changed few options to suit ADA/CEF projection system/screens and checks for win
dow offset.

views.cxx
---------
Added code to retrieve view offset for window.

Main.cxx
--------
Added code to load and move an aircraft carrier.
Patch to enable clouds from command line until Curtis fixes it. By default cloud
s are disabled.
