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);
# which outputs
[ 294.5862574369132, { light_coverage : 0, bumpiness : 0, load_resistance : 1e+30,
solid : 1, names : [ "pc_taxiway", "dirt_rwytaxiway" ], friction_factor : 1,
rolling_friction : 0.02 } ]
With this information it can be determined how far an object would sink in,
if the coordinate is on a runway, etc.
foreach (var n; data[1].names)
if (string.match(n, "p[ac]_*"))

/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.
FGManipulator.*:
"This patch works around a bug in OSG's handling of modifier keys. The
symptom of the bug is that modifier keys don't appear to be released."
fg_os_osgviewer.cxx:
"This patch fixes the test for support of cursor changes in OSG 2.0."
because this allows to load from FG_HOME. To reduce security risks, always
append an ".xml" extension if there was none. Makes it hard to read /etc/secret
and to overwrite ~/.bashrc. :-)
IRC wanted this to be scritable) and add it back (as a tip popup) via
a little nasal in the keyboard handler. Also put the synthesis of
property nodes back into fgcommand(), because I got cold feet.
missing, for sanity. Note that this will pass the resulting NULL
pointer through into the underlying SGCommand handlers, some of which
may be unprepared for it. So basically this is now yet another way
you can use Nasal to exercise bugs and hose your sim; no biggie.
