file. Possible uses of this functionality could include converting the
model to some other format or coordinate system for use in some other
visualization or simulation.
This is required to make sure the same letter key gets released,
which got the press event. (After Ctrl-press -> a-press -> Ctrl-release
a-release we want the Ctrl-a binding released, not the a binding.)
- add key listener interface for direct key access from Nasal space
This removes some jitter in cases where Nasal is used to set up view
parameters from FDM data, such as position and orientation. (The event
subsystem handles Nasal's settimer() calls.)
This was correct in the old repository and in revision 1.1 of the new,
but then broken in revision 1.2. After that, "lookat" and "lookfrom"
mode used different coordinate systems, and the "Adjust View Distance"
didn't work correctly in "lookat" mode.
"I have been investigating the Concorde IVSI problem. I came to the
conclusion that the trouble is that the environment altitude and thus
the pressure (which is calculated from that) is lagging by 1 frame.
Normally that wouldn't be a problem, but the IVSI calculates rate of
change and it will use the new dt with the old value difference,
thereby arriving at bad results if dt changes (and it does)."
invocations, but left it in place for miscellaneous allocation work.
Contexts cache allocated objects in a temps vector and only clear it
out when they are used.
Also, fix a type warning while I'm in there.

* Delete ai list objects in ~ATC/AIMgr.cxx:AIMgr::~AIMgr()
* Delete colors in GUI/new_gui.cxx: NewGui::~NewGui.cxx
* Delete memory allocated to the class member "route" in
Instrumentation/gps.cxx
* Delete all globals (except a few "unsafe" ones that still cause segfaults
and need further examination.
* Use an SGShared pointer for navaid memory allocation, so that pointers to
individual navaid objects can be included safely in multiple navaid lists
- simplify listener purging and fix removelistener() return value for
one-shot listeners
- listener: inherit virtualness
- s/handler/code/ in listener code to be consistent with NasalSys::call
argument:
setlistener(<property>, <func> [, <initial=0> [, <persistent=1>]])
This definition defaults to the old behavior. The fourth argument can
be set to zero, in which case the function is only called when the
node value has actually changed. It should really default to zero, but
then all callers would have to be reviewed, which is a bit too dangerous
"shortly" before a release.
0 -> trigger whenever property is written to (even if it's the old value; default)
1 -> like 0, but also trigger the function initially
2 -> trigger initially, but then only on changes

The additional values are for a first quick&dirty fix just dropped.
remove all those 41 hacks if possible. Metrowerks is under category
"Defunct software companies" in Wikipedia, its compiler was known to
work on PowerPC (which we don't support, anway, right?) and on some
Unices. The hacks are in CVS since the first commit 2002/9/10 (old
repository!) and probably were in the code long before that. Any
platform where such a broken compiler is still used, will hardly
be suitable to run fgfs at all.
them under /sim/presets/ but they aren't save there, and as fgInitPosition
and its subroutines overwrite them, we lose the information about what the
user really wanted. This is a temporary solution -- it really belongs into
options.cxx.
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
OPENSCENEGRAPH_PATCH_VERSION into a single number for comparisons in the
preprocessor.
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

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.
