- 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.
