The problem was that the change to make FGScenery a standard subsystem caused
the particle OSG group to no longer be inserted into the scene graph. The
solution was to convert the particle group to be set up as a standard branch of
the scene graph, alongside the terrain, models, aircraft, and interior branches.
The particle system is now set up as part of the init() subsystem function call,
so it is compatible with the new subsystem design.
This follows from http://thread.gmane.org/gmane.games.flightgear.devel/78650 and
resolves the sign bug https://sourceforge.net/p/flightgear/codetickets/1778/ .
Combined with a matching change to FGData, this changes the HUD formats from the
current set of 3 (note that the text in brackets is not shown in the HUD
preferences PUI dialog, but is show here for reference):
0) Decimal degrees (37.618890N -122.375000W)
1) Degrees, minutes (37*37.133N -122*22.500W)
2) Degrees, minutes, seconds (37*37 08.0 N -122*22 30.0 W)
to (here the text in brackets will be shown in the PUI dialog):
0) DDD format (37.618890N 122.375000W)
1) DMM format (37*37.133'N 122*22.500'W)
2) DMS format (37*37'08.0"N 122*22'30.0"W)
3) Signed DDD format (37.618890 -122.375000)
4) Signed DMM format (37*37.133' -122*22.500')
5) Signed DMS format (37*37'08.0" -122*22'30.0")
6) Zero padded DDD (51.477500N 000.461389W)
7) Zero padded DMM (51*28.650'N 000*27.683'W)
8) Zero padded DMS (51*28'39.0"N 000*27'41.0"W)
9) Trinity House Navigation (51* 28'.650N 000* 27'.683W)
Being able to list arbitrary directories is a privacy violation;
existing in-fgdata uses of this are all permitted paths
(i.e. not Terrasync; FileSelector doesn't use it)
- Use setlocale() to ensure consistent handling of locales and
string handling irrespective of whether or not QCoreApplication
is invoked. Forces a the C locale for numerics and collation,
since many pieces of FG assume this.
I didn’t know about this feature when doing the original CMake files,
we can use this to target header-file includes more precisely.
(Probably more cases exist that can be changed from global to target-
specific includes)
- add a button to the main dialog, explaining how to adjust the
fg-root path via the GUI
- tweak the GUI flow to support explicitly changing the path even
when the default path is acceptable.
- because uiuc_warning_error always called exit(-1), it can be marked
no return, so Clang realises that when it’s used in the ‘else’
side of a parsing test, uninitialised variables in the enclosing
call site are safe.
(Requires Simgear update to define SG_NO_RETURN helper)
- when dynamics shuts down the ATC controllers, they clear their
traffic vectors (destroying the records), but we didn’t notify
the AI aircraft of this. Ensure the controller is cleared so
the AI aircraft shutdown doesn’t crash.
Under some conditions on my system
aircraft_paths.begin() was equal to scenery_paths.end()
This resulted in neither of them being added to read_allowed_paths
followed by failure to load Nasal scripts from the aircraft directory.
This might happen, if scenery_paths gets allocated just before aircraft_paths
in memory.
Better loop across the desired lists instead of using fancy tricks with
the iterator.
- sim-speed-up (a/A keys) offsets warp correctly. This means at 4x speed
up the warp will increase by 3 seconds for one elapsed real second.
In practice this means simulation elements timed using sim ‘current time’
will be correctly synchronised with those using simulated elapsed time.
(AI traffic being a prime example of this)
- warp-delta (t/T keys) is independent of frame rate, and works when
paused. The warp-delta values in the keybindings / GUI dialog
will need to be updated since warp-delta in now seconds-per-second,
as opposed to seconds-per-frame.
- change launcher to examine the scenery paths and hence load
ground-net files for airports to populate parking data.
- refactor ground-net XML parsing to use FGGroundNetwork only, not
AirportDynamics.
- change parenting of GroundNetwork to Airport, since it contains
immutable data now.
- when no runway use preferences XML exists, be smarter about using
available runways. Makes the common case of using two parallel
runways for arrivals and departures work, greatly improving AI
traffic behaviour.
- consistent with pause (freeze), /sim/speed-up is now applied to the
dt value for all subsystems, not just the FDM and some instruments.
For example AI traffic can now be sped-up or slowed down.
- requires both an FGData and Simgear update.
