the next airport or airport with METAR station, but about any type of
airport
- as a side effect this change makes it also 30 to 50% faster :-)
In the long run this linear search shall be replaced with a spatial
algorithm (like octree), which will be a much bigger performance gain.
- preserve information from apt.dat about whether an airport is a "normal"
airport, a seaport, or a heliport. Do it without wasting another byte
in the FGAirport structure (saves 50kB of memory). Yes, I know bitfields. :-)
Turn OPENSCENEGRAPH_MAJOR_VERSION, OPENSCENEGRAPH_MINOR_VERSION and

the runway length/width/surface material, so that fgfs doesn't drop one on
the ridiculous grass stripe parallel to the grown up concrete runway
(LOWL, LOXZ, ...). The weighting factors are for now made configurable,
so that they are easier to adjust. This can later be made static.
(will soon get forward ported to fg/osg)
Usage: airportinfo("KSFO");
airportinfo(37, 122); # airport closest to lat/lon
airportinfo(); # airport closest to current position
Returns nil on error, or a data hash otherwise. Example:
# length of runway 28R
var len = airportinfo("KSFO").runways["10L"].length;
Note that only one side of a runway is returned.
This fixes a bug that caused both the x and y values of the mouse to
be reset when the cursor was recentered due to hitting the screen
edge.
Based on a suggested patch from Stuart Buchanan
Anders said:
With Stuart's help I've looked closer at this and I think I've tracked
down the cause of the problem:
At least on my computer the sort() call on line 234 in
Environment/environment_ctrl.cxx sorts the vector entries by memory
address instead of altitude, i.e. the custom comparison predicate is not
used. This causes the tables of environment conditions to be reordered
into a wrong order at some weather updates, depending, basically,
on where the memory allocator places the objects. (Btw. why are they are
freshly allocated for each update?)
and "isOnRunway".
- Added initial support for AI controlled pushback operations, making use of the
current editing capabilities of TaxiDraw CVS / New_GUI_CODE. The current
implementation is slightly more computationally intensive than strictly
required, due to the currently inability of taxidraw to link one specific
pushBack point to to a particular startup location. FlightGear now determines
this dynamically, and once we have that functionality in TaxiDraw, the
initialization part of createPushBack() can be further simplified.
- Smoother transition from pushback to taxi. No more skipping of waypoints, and
aircraft wait for two minutes at pushback point.
- The classes FGTaxiNode, FGTaxiSegment, and FGParking, now have copy
constructors, and assignment operators.
- Removed declaration of undefined constructor FGTaxiNode(double, double, int)
- Array boundry checks and cleanup.
- Modified Dijkstra path search algoritm to solve partial problems. Currently
limited to include pushback points and routes only, but can probably be
extended to a more general approach.
- Added initial support for giving certain routes in the network a penalty, in
order to discourage the use of certain routes over others.
"interpolates METAR changes over time as follows:
1) Wind changes are interpolated as vectors, so the change is much more
natural than before - no-longer will your aircraft be suddenly shoved to
one side.
2) Visibility is interpolated as an X-value, which looks pretty neat.
3) Cloud heights and thicknesses are interpolated if they are close to the
aircraft. Cloud textures are not."
- support optional <preamble> and <postamble> which are written right
after opening and before closing respectively. This can be used for a header
line or an XML header.
- unescape <preamble>, <postamble>, <format>, <line_separator>, <var_separator>
so that \t, \n, \r, \f, \v, \xnn, \nnn can be used directly (\a and \b are
ignored; use \\ for the backslash) The long names ("carriagereturn") are still
supported for <var_separator>, but one can just use \r, or \r\n too.
- don't abort when a chunk doesn't have a <node>. This is useful for adding
constant chunks which consist only of a <format>, such as XML tags.

own preferential runway support. In future versions, we might want to
condider having a more generic mechanism for this.
- Keep a history of active runway for each class, so that runway assignments
are more consistent after whether updates or time-related schedule changes.
On most Unix platforms like FreeBSD, Solaris, IRIX (AIX is even worse)
- just not on Linux - the linker wants to know about _all_ required
libraries. So even if a shared library "libosgViewer" itself is linked
against "libosgGA" and "libosgText", you still have to name these in
order to build an "fgfs" binary.
Currently, other libraries like "-losgDB" and "-losgUtil" are
explicitly mentioned on the "fgfs" linker command, but "-losgGA" and
"-losgText" are not. This simple patch lets the linker honour
everything that's required

I refactored the XML loading code out of FGAirportDynamics and
FGRunwayPreference. I also added a new class XMLLoader, which serves as a
facade to the loader functions. Further I changed FGRunwayPreference to just
keep a FGAirport ref, which is more concise and closer to the right(tm)
solution than storing the airport data a second time ;-)

Usage: parsexml(<path> [, <start-tag> [, <end-tag> [, <data> [, <pi>]]]]);
<path> is an absolute file path, the rest are optional callback functions.
Example:
parsexml("/tmp/foo.xml", nil, nil, func(d) { print("DATA FOUND: ", d) });
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.
efficiently performing "Dijkstra algorithm".
Durk Talsma: Added the detection of "circular" wait situations in the AI
ground network. A circular wait is a situation where aircraft a waits for
b; b waits for c; and c (in turn) waits for a. The checkCircularWaits
function detects these situations.
The current "solution" to a circular wait is rather crude: Remove the
aircraft from the scene. A proper solution needs a lot more work, however,
and at least this patch stops the AI system from clogging up. in case of a
circular wait.

backup. This database will allow the calculation of aircraft-specific
take-off speed and estimate runway lenght requirements. Further added
rudimentary support for take-off and landing rotation of AIAircraft.

or nil if no terrain intersection could be made (tile not loaded yet).
<matdata> is a hash with information about the surface material, or nil
if no material is assigned (shouldn't really happen, but one never knows).
Example:
var ac = geo.aircraft_position();
var data = geoddata(ac.lat(), ac.lon());
debug.dump(data);

rolling_friction : 0.02 } ]
With this information it can be determined how far an object would sink in,

/sim/screneryloaded-override was "true". At least one subsystem (od_gauge)
waits for /sim/sceneryloaded to bypass CPU intensive code until the scenery
is up. This broke e.g. the RTT-radar when using /sim/screneryloaded-override
--prop:sim/sceneryloaded-override=true has the effect that fgfs
doesn't show the splash screen until the scenery is loaded, but shows
the OTW view (scenery/aircraft) at the earliest possible moment. This is
useful for developers who often need to run fgfs only to check some minor
detail, while not caring about stuttering caused by scenery loading.
simple SG_LOG instead. The user didn't call the fgcommand, so why should
s/he be bothered with that? And the actually caller of the command gets a
return value and can pop up a dialog if it thinks it's necessary.
Why /sim/fg-current at all? Because we have a file selector dialog
(still unfinished), and one might like to start it from the current
directory, to find saved flights/screenshots/whatever.
