We set /environment/metar/description to human-readable description of metar,
for use by fgdata's weather dialogue, using simgear FGMetar's new description()
method.
Use a new SGPropertyNode flag, LISTENER_SAFE, to white-list properties
where we do correctly fire listeners, and test this flag when listening
from Nasal, to avoid the warning.
One test so far, attempting to reproduce a bug I see with the 737.
Note these tests are skipped unless you have procedures available
and set a magic env var to find them.
Ensure changes from Nasal are picked up by delegates (such as GPS) when
they are made. Add a route-manager test which sets and exits a hold
using Nasal.
As part of this, update the test API to make it easy to run Nasal from
a test.
The GPS/RNAV system can now fly holds, both left and right-handed.
The correct entry is selected, and hold count can be selected.
Also there's lots of lovely test cases.
Avoid screwing up the derived / trend data when we are repositioned;
detect instantaneous position changes and don’t update the trend
data in this case.
GPS now lets the delegate handle the sequencing behaviour, by
setting a new config property. The default GPS delegate (in Nasal)
now sets this property.
This requires a corresponding FGData update.
- set wp[1] properties immediately (don’t require an update cycle)
- direct-to course-error is correct when init-ing the Direct-To; it
was previously wrong when beginning the DTO, due to invalid course
between identical SGGeods.
FlowRegime to wing definitions). (Daniel)
//amended according to James hints: change initializer to float constants, fix indention issues, add Math::polynomial and use it in Surface. (Henning)
The existence of the property that is used for <table> independent vars is now checked during execution rather than when the XML definition is parsed. This relaxes the order in which filters, table and more generally flight controls need to be declared in the XML definition files.
E.g. fgaddon/Aircraft/Icaro_MRX13/Icaro_Laminar_13_MRX-set.xml sets
/sim/current-view/view-number to 9.
It seems that recent View changes broke this, but this fix is in unchanged
code.
Prior to the recent multiplayer view changes, /sim/current-view/?-offset-m
contained the current view's offsets from /sim/view[]/config/?-offset-m. The
multiplayer view changes modified things to set /sim/current-view/?-offset-m
to zeros, and instead use /sim/view[]/config/?-offset-m. This was so
that multiplayer views could be implemented simply by prefixing with
/ai/models/multiplayer[]/set/ to get the right offsets.
We still added in /sim/current-view/?-offset-m, but these were usually zero.
However some aircraft write to /sim/current-view/?-offset-m, and assume that
values must include the /sim/view[]/config/?-offset-m. E.g. the spaceshuttle
does this in order to simulate SRB shaking. This results in the offset being
included twice, which breaks things.
So this commit restores the original handling of /sim/current-view/?-offset-m
by doing an additional subtraction of /sim/view[]/config/?-offset-m. It also
avoids resetting /sim/current-view/?-offset-m to zeros when the view changes.
This results in views working for user aircraft, user aircraft that do custom
view handling, and multiplayer aircraft.
- [Backward compatibility breakage] Gyros are now measuring rotation rates instead of rotational accelerations. Gyros that measure rotational accelerations do not exist in the real world.
- Output properties of flight control elements are no longer tied. This saves a lot of spurious warning messages and allows direct references of the same properties among several flight controls.
- Water vapor in the atmosphere is now managed through its mass fraction rather than its partial pressure. The former being the physical quantity that is conserved when pressure and temperature vary.
- Check that there are at least 3 contacts before trying to trim on ground.
- ECEF to ECI frame conversion has been moved from FGLocation to FGPropagate and FGInitialConditions since not all FGLocation need to manage that.
- Gravity computations have been moved to FGInertial because it is where all the constants to compute gravity are stored. This reduces the amount of data transmitted between FGInertial and FGAccelerations.
- Added optional transmission of the simulation time for FG UDP interface
- Code cleanup and use more C++11 idioms (override, constexpr, range-based for loop, etc.)
We now keep the aircraft in view when zooming, sacrificing the view of the
ground. I.e. we move the bottom of the view upwards, while keeping the top of
the view unchanged.
Recent changes to ViewPropertyEvaluator mean that
ViewPropertyEvaluator::getDoubleValue() doesn't handle default values very
well, so we were ending up with chase-distance of zero, not the default -25,
leading to over-zooming.
Un-caching of scenery appears to happen fairly often, and means that we fail
to find height of ground under aircraft, so we now go back to the last found
value instead of using zero.
This allows Tower View etc to use nearest tower when vewing remote multiplayer
aircraft.
Also force an update of nearest airport whenever multiplayer view changes, to
reduce delay before Tower View works.
