We previously only showed the magnitude of the thrust; this patch uses the sign
of first element of thrust vector. Makes things less confusing if an engine is
stopped or otherwise causing drag rather than thrust.
Uses these properties:
/sim/atis/speed
/sim/atis/volume
/sim/atis/pitch
Values 1.0 behave as default. Other values are used to multiply default
settings.
Changes don't take affect immediately. But changing com frequency seems to
often cause an update which will then pick up the new values.
Increased diagnostics from SG_WARN to SG_ALERT, to mitigate confusion if METAR
is out of date etc.
Will add a better mechanism for reporting errors at some point.
Changing style will reload style from filesystem, so one can edit styles and
see results without restarting fg.
Note that this duplicates initial populating of /gui/styles/ from
defaults.xml's <sim><gui>...</gui></sim> section, so it's a bit of a hack.
If user specified --load-tape then failure to load it should be fatal to avoid
confusion. It also avoids needlessly overwriting a valid recovery tape if
/sim/replay/recovery-period is set.
Throwing an exception was too harsh. Instead the clipping is ignored and a warning message issued.
Reintroducing the commit 90a04a that has been inadvertently removed.
These were due to the ground callback instance of FlightGear not setting the ellipse parameters of the 'contact' location. this commit make JSBSim immune to that scenario.
Includes the following new features and bug fixes:
- The <random> function now uses C++ std::default_random_engine
- WGS84 is now used everywhere in JSBSim (previously a mix of spherical/WGS84 earcth was used resulting in inaccuracies).
- A new <planet> XML element can be used to tweak the planet characteristics (such as semimajor/smemiminor axes, gravity, etc.)
- The FGGroundCallback instance is now managed by FGInertial with a dynamic pointer std::unique_ptr<>. JSBSim was previously using a static pointer which was causing memory access failures when several instances of JSBSim were used or when an instance was replaced by a new one (the structure pointed to by the static pointer was then lost when the old instance was destroyed).
- Removed calls to exit() and replaced them by exceptions that can be caught by FlightGear (should avoid FlightGear from being ungracefully stopped by an error found by JSBSim).
- Sockets interface: replaced the usage of obsolete functions gethostbyname()/gethostbyaddr() by getaddrinfo().
- FGColumnVector3 and FGMatrix33 can now be initialized by C++ std::initializer_list
- Disable the delays implemented in some flight control components during trimming (was sometimes preventing the trim algorithm from converging to a solution).
- Fixed the magnetometer initialization (was not updated during the first 1000 time steps)
- More conversions to C++11 features (nullptr, override, std::unique_ptr<>, etc.).
Since our data encoding is incompatible between 2018 and 2020, use
different settings keys so running both versions in parallel is easier.
Without this, each version screws up the data for the other.
