New module contributed: AV400WSim.
Supports communication with external (aka real) Garmin 400/500 WAAS flight
sim units. Includes changes to options.cxx and fg_io.cxx to support
invoking and configuring the new module.

work again. These options now write properties in the
/environment/config/presets
branch. The values will be applied in the property-rules
in FGDATA/Environment/interpolator.xml
- #248: new enable/disable-ai-traffic command-line option
- AI traffic: don't wait for METAR when real-wx-fetch disabled, to
enable AI traffic when running offline
This is the initial commit for a reworked environment controller.
The main intention is to decouple the individual modules like
metar fetch, metar properties, environment interpolation etc.
to make it easier for other weather module developers to modify
environment settings.
As a side effect, the dialogs for weather-scenario, weather-conditions,
clouds and precipitations have been merged into a single dialog
Add helper to look for an aircraft branch path in multiple candidate locations.
Update the main subsystems to use the helper, and hence load from any aircraft dir.
* Add a new command line option: --sound-device=""
This makes OpenAL use the sepcified audio device instead of the default
output device. (Look for playback devices when calling openal-info of alcinfo)
Move fgviewer code into fgfs binary. Its osgViewer-style main function is
called from bootstrap.cxx if the --fgviewer argument is passed to fgfs.
Use fgfs initialization functions in fgviewer codepath. Read
command-line arguments and autosave.xml.
- Runways are now part of an airport, instead of a separate list
- Runways are no longer represented as a boring struct, but as a class
of their own.
-Improved runway access to unify various runway access methods.
CameraGroup supports cameras opened in different windows or in the
same window, with flexible view and perspective specification.
Clean up mouse click handling via osgViewer. Don't let any camera
"have focus;" this forces events to be reported in window coordinates
and simplifies life. Don't use the osgViewer::View::requestWarpPointer
method; instead use our own code which only deals with window
coordinates.
Make glut and sdl versions work with CameraGroup too.
- this exposed a bizarre issue on Mac where dragging in <AGL/agl.h> in
extensions.hxx was pulling in all of Carbon to the global namespace
- very scary. As a result, I now need to explicitly include CoreFoundation
in fg_init.cxx.
- change SG_USING_STD(x) to using std::x
SimGear change. It changes all the SG_xxxx to be the 'real' includes, and gets
rid of many #ifdef SG_HAVE_STD_INCLUDES. As an added bonus, rather than
replacing 'SG_USING_NAMESPACE(std)' with 'using namespace std', I just fixed
the small number of places to use std:: explicitly. So we're no longer polluting
the global namespace with the entire contents of std, in many cases.
There is one more 'mechanical' change to come - getting rid of SG_USING_STD(X),
but I want to keep that separate from everything else. (There's another
mechnical change, replacing <math.h> with <cmath> and so on *everywhere*, but
one step at a time)
$ fgfs --version
2.0pre-20080314
FG_ROOT=/usr/local/share/FlightGear
FG_HOME=/home/foo/.fgfs
... assuming that VERSION in config.h is "2.0pre-20080314". Which it isn't.
Instead it's "1.0.0" since yesterday, and was "0.9.10" before that. This
has yet to be discussed, and I'll add the option to options.xml later.
where type is one of string (default), double, float, long, int, bool
Using only the first letter works, too.
--prop:foo=123 ... sets property foo to string 123 (old behavior)
--prop:string:foo=123 ... verbose version of above
--prop:s:foo=123 ... slightly less verbose version of above
--prop:bool:foo=1 ... makes property a bool of value 'true'
I hope this isn't considered a silly gimmick. I need this often and maybe
other developers do, too. It's useful in cases where the difference really
matters. if (getprop("/foo")), for instance, is TRUE even when the property
contains string "false", as all strings are TRUE.
- props is easy to mix up with the --prop option (for setting properties)
- the name is unspecific and inconsistent: other option names describe
the protocol -- the way to get the properties. How is, for example,
--httpd less about prop(ertie)s?
- two identical options easily confuse people, as can be seen in The
FlightGear Manual, where --telnet and --props were described differently

format. I have a Garmin 295 to test with, but so far I haven't been able
to make this work (code should compile cleanly though.) I don't know if
I've made a mistake in the protocol or if my 295 just doesn't support this.
More work on this to come.
into the <color> group, but that's because on HUD color changes a whole
"color" set from /sim/hud/palette/color[*] is copied to /sim/hud/color/, and
antialiasing needs to be considered with that. (I'm not entirely happy
with the property names yet.)
- only call globals->set_initial_waypoints() if the waypoints list address
has actually changed, that is: if it has just been initialized
- remove trailing spaces
- fix indentation
The new multiplayer patch with an extension to transmit some properties with
the base package. The properties are transmitted in a way that will not
immediately brake the packet format if we need new ones.
Even if the maxmimum number needs to be limited somehow, that format might
work well until we have an improoved packet format which is even more compact
and that does not require to retransmit redundant information with each
packet.
That part is relatively fresh and based on that what Oliver provides on his
multiplayer server web page.
The properties are transferred to the client and I have modified the seahawks
rudder animation property to use a relative property path to verify that it
works appart from the fact that you can see it changing in the property
browser.
The movement is still a bit jerky, but that can be fixed/tuned later without
again braking the packet format.
* in some cases more specific sg exception types were used in place
of the more generic one, e.g., sg_io_exception instead of sg_exception
when the context of the error was an IO error
* in some cases, the error message was made more specific
* minor style fix for exception rethrowing --- using throw; whenever
a re-throw is made; sometimes optimizing away the exception symbol name
in the catch handler at all
* more specific catch handlers added in some places -- e.g.,
an sg_io_exception caught ahead of sg_exception
I stumbled across two memory errors with two wrong const references to
std::string.
As I fixed that, I also moved aircraft_dir which is only used from UIUC into
UIUC. With that uiuc_aircraftdir.h is empty and can be removed.
Changes
=======
- acmodel.cxx :
we now have an optional new property (/sim/model/texture-path) that is used
as the first path in wich aircraft textures are searched. If textures are not
found there then the usual texture path or model path is used ;
This allows to replace only needed textures for liveries ;
- options.cxx :
added a new --livery=xxx option for the user pleasure ;
this will just set the /sim/model/texture-path property with /livery/xxxx
- od_gauge.cxx, og_gauge.hxx, cockpit.cxx, cockpit.hxx,
generic-instrumentation.xml :
added an helper class that contain a rendering context for glass instrument
or any other opengl drawn instrument ;
- wxradar.cxx, instrument_mgr.cxx, wxradar.hxx :
first experimentation of a weather radar ;
I have introduced the posibility to start directly on the carrier.
With that patch you will have a --carrrier=id argument where id can either be
the pennant number configured in the nimitz scenario or the carriers name
also configured in the carriers scenario.
Additionaly you can use --parkpos=id to select different positions on the
carrier. They are also configured in the scenario file.
That includes the switch of the whole FGInterface class to make use of the
groundcache.
That means that an aircraft no longer uses the current elevation value from
the scenery class. It rather has its own local cache of the aircrafts
environment which is setup in the common_init method of FGInterface and
updated either manually by calling
FGInterface::get_groundlevel_m(lat, lon, alt_m);
or implicitly by calling the above method in the
FGInterface::_updateGeo*Position(lat, lon, alt);
methods.
A call get_groundlevel_m rebuilds the groundcache if the request is outside
the range of the cache.
Note that for the real usage of the groundcache including the correct
information about the movement of objects and the velocity information, you
still need to set up the groundcache in the usual way like YASim and JSBSim
currently does.
If you use the native interface, you will get only static objects correctly.
But for FDM's only using one single ground level for a whole step this is IMO
sufficient.
The AIManager gets a way to return the location of a object which is placed
wrt an AI Object. At the moment it only honours AICarriers for that.
That method is a static one, which loads the scenario file for that reason and
throws it away afterwards. This looked like the aprioriate way, because the
AIManager is initialized much later in flightgears bootstrap, and I did not
find an easy way to reorder that for my needs. Since this additional load is
very small and does only happen if such a relative location is required, I
think that this is ok.
Note that moving on the carrier will only work correctly for JSBSim and YASim,
but you should now be able to start and move on every not itself moving
object with any FDM.
I have added a --aspect-ratio-multiplier=x.xx option to give some end user
control over the aspect ratio. (This may seem a little strange, but it's a
building block towards the capability of doing asymmetric view frustums in
FlightGear.)
After applying the attached patches (based on latest CVS) you should
have a new option available within your version that should also
show up using fgfs --help, the syntax is:
fgfs --min-status={level} --show-aircraft
whereas "level" can be anything between
"alpha","beta","early-production" and "production"
Of course running something like
fgfs --min-status=alpha --show-aircraft
should not return any aircraft right now, as none of the
current aircraft definition files in your base-package is using the
required
<status></status>
tag - but you can easily give it a try by adding something like
<status>alpha</status>
The tag should be placed as a sub-tag within <sim> - so directly behind
the <description> tag would be just fine and straight-forward.
