I was playing with the target tracking and decided to fix an old bug that causes it to behave wrong at higher altitudes.
Background: the script continuously updates values in the autopilot to follow specified target aircraft (AI/MP). It is controlled directly through the property tree under /autopilot/target-tracking.
Issue: the script reads out true airspeed, but autopilot expects indicated airspeed. This is why at higher altitudes, the tracking always overshoots.
I fixed this by introducing an estimate on indicated airspeed of the target, using the ratio between local aircraft true and indicated airspeed.
I also fixed an issue where it ignored minimum speed setting and polished initialization by using props.globals.initNode() instead of dedicated presence check for every property (and also ensured the nodes have correct types, no more bool stored as double). And the last thing I changed was to increase the default tracking distance to a more sane value, with the original value of 0.05nm the tracking was unstable in heading with most aircraft and started oscillating.
With the changes I applied, the distance is now holding precisely at any altitude and with any winds.
Current GUI allows selected mis-matched STAR and approach. Low risk
fix is to detect and deal with this case by just routing direct. Real
fix involves a slicker GUI or inserting a route discontinuity (possible
in FG 3.6 hopefully)
-fix a severe bug which led to unintended hitch releases;
-include the new JSBSim external force location variables;
-improvements for function closeHitch
- Fix: runtime exception in remove_failure_mode()
- Fix: keep failure & trigger status on teleport.
- Fix: allow random failures from the gui to be enabled/disabled multiple times.
- Fix: mcbf/mtbf are set to zero when they fire, so they can be reactivated from the gui.
- Fix: string casts of several trigger types had syntax errors.
- Usability: screen messages related to failures now use positive logic:
"condition 100%" instead of "failure level 0%"
- Performance: Time triggers now use internal timers, instead of requiring being polled.
- Reviewed Trigger interface for more rational usage. reset() is replaced by arm()/disarm()
- Added a subscription interface to listen to FailureMgr events.
- Added an internal log buffer to keep a record of relevant events and present them to gui elements.
- Several usability improvements to the FailureMgr Nasal API.
The reason it didn't work for me is that
/sim/rendering/camera-group/camera/viewport/ does not seem to contain
the actual dimensions of the view window... which is odd. Instead I'll
use /sim/startup/[xy]size (and make it into a method so I don't have to
change 3 lines next time :). Now that it works (again), it looks so much
better. Thanks to Alexis Bory for the original idea.
Only show max 50 aircraft by default and provide a "Show More"
button. This prevents locking the GUI for up to nearly 15 seconds
with showing the list of all aircraft.
Rewrite the way scrolling for ScrollAreas is handled: Store
content position instead of scrollbar positions to keep position
on resize and promote moving the content instead of the contents
to as primary API.
Let the mousewheel scroll by fixed content offset instead of
scrollbar offset to make it actually usable (especially with
low scrolling distance).
- Increase default size.
- Run parse_markdown on description to remove multi
whitespace, possible present in catalog.xml and
also support simple, one-level bullet point lists.
- Needs FlightGear compiled with -DENABLE_PACKAGE_SYSTEM.
- Shows only first 100 available aircrafts.
- Now progress indication on install/remove (need to reopen
dialog afterwards)
- Making run_tests accept a target namespace as an argument.
- Fixed asynchronous trigger callback mechanism.
MCBF triggers working again.
- Fixed numerical problems when calculating standard deviation
for rand triggers.
Replaces existing Nasal/failures.nas script with a programmable failure
manager. The failure manager allows dynammic creation and removal of
failure modes, on demand activation and a flexible set of triggers.
The public interface can be found in Nasal/FailureMgr/public.nas
Aircraft/Generic/Systems/failures.nas provides a library of triggers and
failure actuators ready to use for programming the failure manager.
A compatibility layer is included under
Aircraft/Generic/Systems/compat_failure_modes.nas.
This compatibility layer is currently loaded on startup and programs the
FailureMgr to emulate the former behavior (same set of failure modes and
compatible interface through the property tree).
This first milestone is only intended to replace the failure management
engine underneeth with minimum visible changes, and hopefully no aircraft
breakages. Future milestones will build upon this to add a Canvas based
procedural GUI and example integration on aircrafts.
- A simple assert() function is added to the globals namespace.
- io.include() marks the target namespace to avoid dependency loops.
If the namespace is marked before the script to be included is
compiled, a parse error leaves the target namespace marked while
the script has not been loaded. This patch fixes this problem.
Fix the main bugs, add features and convert most of the layers.
Move/refactor some things as well. Add a canvas map dialog next to the
built-in one -- it's not 100% functional but it's quite close actually.
As before, the excitement has been taking place at our team clone.
https://gitorious.org/fg/canvas-hackers-fgdata/commits/0b4cc84
(topics/canvas-map-dialog branch this time, current HEAD in above URL.)
Features:
- Various configurable styles.
- Working scroll bars, thanks to Tom
- Adequate REPL-ness.
See the wiki for more information!
http://wiki.flightgear.org/Interactive_Nasal_Console
N.B. This makes some (sane) changes to other Nasal files, including
expanding some of the Canvas API.
Add benchmark_time, rank, and print_rank. Modify benchmark to return/
pass-through the values of the function, appending to a vector if there
are multiple executions.
- Calculate bounding box after adding all children.
- Apply rotation after all SVG defined rotations to use correct
center of rotation (as defined in Inkscape)
This (together with the SimGear and FlightGear commits) fixes
the core problems of #1333.
Implement traffic in MapStructure and use it. Various other hacks and/or
cleanup. Feedback required on whether this is a lot better than before.
Also partially revert 9c018d94c4d88dad7476ec250fa3b52024526f4b to add
feature to geo.PositionedSearch: it me._equals is overridden then the
old mechanism is used instead of the new C++ function, so that the
custom equality can be used. (In particular for the Fixes with the
TrafficModel class).
Make fdm listener single-fire, don't listen to /sim/signals/reinit. This
allows the Canvas to stay with the same placement through reinit, after
both the 777 and 747 were having problems. I don't see any reason for
having to recreate it all, and the cleanup function is still there (e.g.
for independent windows, to have their .del() call the ND's .del()).
renamed handle_reinit() -> del()
This also makes sure the /canvas/by-index/canvas[3/4]/ nodes are removed
and then recrated, as well as making sure the MapStructure del() path is
followed and working. Unfortunately the NDs are still blank after reinit.
The old API is not used with newer versions of FG. If an old
version of FG is used, also the according version of fgdata
should be used, which also includes the correct API wrappers.
In time for 3.0. The API is still not fully complete, and not fully
cleaned up, but this is good enough for this release cycle (and it
should offer benefit longer term, if not now -- hopefully performance as
well).
Many thanks to Hooray as well, who has helped prepare things while I
could not, and often suggested ideas.
io.inlude() loads and executes a Nasal file in place, effectively embedding
the script in the calling namespace. The function adds a symbol mark in the
namespace to avoid duplicate loading.
Additionally, in this path:
+ io.basename() & io.dirname(): Convenience functions for managing path
strings. Designed after their unix counterparts.
+ string.normpath(): Improved support for relative paths. It can now handle
paths starting with double dots, like ../../Directory
This require less interaction between Nasal and C++ and
also does not need to create a list of removed children
which was not used anyway. Now it require about 70% less
time to execute.
- move SVG to Canvas directory
- add basic wxradar
- differentiate between track and heading
- improve altitude arc
- add range arcs
- display correct ETA for next waypoint
- get rid of global variables and use instance variables
- identified all important drawing routines and move them into *.draw files
- changed to dynamic loading of *.draw *.model and *.layer files
- implemented poor-man's controller hash to move use-case specific conditionals out of the draw files, and back into the instantiation, i.e. Gijs' EFIS class
- started identifying stuff that is not specific to drawing, but to what is to be drawn, i.e. Model stuff - such as positioned queries, moved those out into *.model files
- some more work on supporting more than a single ND MFD instance per aircraft
- renamed a handful of SVG identifiers to avoid naming conflicts and to simplify usage of SVG IDs as member fields
- moved all of the setlistener setup out of the fdm-initialized stub right into the ctor of the Efis class (actually that's controller stuff...)
- initial MapStructure framework
- aircraft-agnostic NavDisplay class
- preparations for deprecating map.nas
- additions to canvas.map
- preparations for making NDStyles configurable via XML
Replace the temporary UI with real solutions, in the view dialog
(for tooltips/popups) and a new 'input config' dialog accessed via
the file menu.
Make the mouse-cycle popup explicitly optional since some people
strongly dislike it.
* make into singleton class
* make sure FOV changes take place *immediately* when required
* current FOV is scaled with changes, though being preserved: resizing
window and going back ends up with the same FOV
mathlib.c now defines more of these. Remaining items (abs, sgn, min, max)
are likely faster using Nasal than switching to C and back again.
Also add a comment about mod(), clarifying that a native fmod() exists.
- Canvas window placements now use 'id' instead of 'index'...
- Provide Dialog class for backwards compatibilty (but print a
warning that it will be removed)
- Remove 'px' suffix from numbers to be used as valid numbers.
- Automatically update the rotation center if it the according
values are present.
- Fix text only partially set if containing xml entities.
Extend the canvas.Window class to create a simple window decoration
if a type for it (currently every type maps to the same style) is
given. It supports moving the window by dragging inside the title
bar and setting a window title.
Hyde identified a problem where the departure and destination
runway are identical; the logic would detect a 'landing' on
activation and immediately deactivate the FP again.
- Make the A330-MRTT drogues HOT=false so you can't crash into them
- Add offset for the probe on the A-4F
- Correct the deviation due to roll, making it match the piloted aircraft.
Drive off the 'show view names' checkbox in the view dialog for now, this might
evolve into a generic 'on-screen hints' control to avoid an explosion of
GUI checkboxes.
Also add a GUI checkbox (oh the irony...) to disable mouse flight-controls, to
keep AndersG and Emilian happy.
Null the tooltip ID in update-hover, regardless of visibility. Avoids later tooltips when picking other (tooltip-less) pickable objects.
Also add two more mapping models for bools: up-down and down-up.
add a 'heading' mapping mode, normalises to 0..360
support a 'measure text' property used to compute the tooltip size (and hence avoid visual jitter when value is changed)
This is temporary (hopefully!), to allow experimentation with different UX options in the near future. Right now it basically does nothing. As part of this, factor mouse-mode cycling into a separate command, and add some feedback. Feedback mechanism needs work, currently abusing the copilot facility.
This should give no visible change on platforms other than Mac. On Mac file-dialogs (open, save, choose dir) are now Cocoa native panels, not PUI. If someone wants to create a Windows equivalent, the API is pretty trivial.
- std.string:
* Add method compare
* Add method starts_with
- canvas.Group:
* Add method rect for drawing (rounded) rectangles
- Rename canvas.Dialog to canvas.Window to free the name Dialog
for real dialogs.
Fix bug 940, where GPS remains in active LEG mode when the route is cleared. (there is an associated flight gear code change). With this fix, the work-around in the GUI dialog is no longer required.
This should help those checking out models in fgviewer
To enable effects in fgviewer run it with:
fgviewer --prop /sim/rendering/shaders/quality-level -1
Also fix random buildings not showing up when model shader was set to 0 and generic was enabled.

- first stab at refactoring the map.nas module, and trying to let the API evolve according to our requirements
- split up the module into separate files (some of them will disappear soon)
- split up the "drawing" loops into separate functions so that they can be individually called
- move actual "drawing" to map_layers.nas
- introduce some OOP helpers to prepare a pure Layer-based design
- prepare helpers: LayeredMap, GenericMap, AirportMap (TODO: use a real "Layer" class)
- move airport features (taxiways, runways, parking, tower) to separate layers (i.e. canvas groups)
- avoid using a single update callback and use different layer-specific callbacks to update individual layers more efficiently
- add some boilerplate hashes to prepare the MVC design
- allow lazy updating of layers, where canvas groups are only populated on demand, to save some time during instantiation, i.e. loading an airport without "parking" selected, will only populate the layer once the checkbox is checked
- extend the original code such that it supports showing multiple airports at once
- add some proof of concept "navaid" layer using SVG files for navaid symbols (added only NDB symbol from wikimedia commons)
regressions:
- runway highlighting needs to be re-implemented
- parking highlighting will be done differently
- enforcing a specific drawing order for layers is currently not explicitly supported, so that taxiways may be rendered on top of runways
Also:
- integrated with the latest changes in git/master (HEAD) -i.e. metar support
- further generalized map.nas
- partially moved instantiation from Nasal space to XML space (WIP)
- create "toggle layer" checkboxes procedurally in Nasal space
- prepared the code to be better reusable in other dialogs (e.g. route manager, map dialog etc)
- completely removed the "highlighting" (runway/parking) feature for now, because we talked about re-implementing it anyhow
- Display taxiways
- Display different surface types
- control over components (taxiways, parking positions, towers) displayed
- include distance and course to airport.
A fire log can now be loaded at startup time with, e.g.,
--prop:environment/wildfire/events-file=$HOME/.fgfs/Wildfire/small_fire.xml
(Note: Wildfire is only authorized to load logs from ~/.fgfs/Wildfire .)
Additionally, a time at which the fire starts to evolve (past the event log)
can be specified with, e.g.,
--prop:environment/wildfire/time-hack-gmt='2012:08:23:15:15'
Instances of FlightGear that are started with the same event log and time-hack
should arrive at similar wildfire states (prior to new events).
- API:
* Rename setSize to setFontSize
* Add method getElementById to Group
* Rename name of element to id to show more prominent
that it should be unique.
* Add methods for hide/show elements.
* Fix: set correct id for cloned elements (parsesvg)
* Fix: retrieving group with getElementById failed.
* Parse SVG inkscape:transform-center-[xy]
* Allow rotation around given point (use values from inkscape
by default for SVG files)
* Use breadth-first search instead of depth-first search for
Element::getElementById (large speedup :))
* Add more convenience functions for path drawing.
* Add version check (useful if API files manually copied)
- SVG:
* Support <use> element
* Parse font-size
* Parse stroke-linecap
- Fraction of each tank capacity displayed, along with pounds and gallons
- Total fuel is now displayed
- CofG displayed if available even if /limits/ not defined (bug fix)
- Tanks of capacity 0 ignored (bug fix)
- Some layout improvements.
Addresses issue #778
Throttle/aileron/elevator keyboard bindings did not work on aircraft
without autopilots (= without A/P properties). Rearrange logic to make
basic axis/throttle control the default (i.e. when prop values are "nil").
This is a new button in the pilot list, left of the callsign. It's
binded to multiplayer.compose_message("<CALLSIGN>, ");

"/sim/signals/fdm-initialized" triggers _every_ time the FDM is reset,
so for every sim reset/relocate.
We need to uninstall the listeners after its first execution, or guard
certain parts of the initialization, to avoid starting multiple
"timer/update loops", or installing multiple property listeners.
Repeating "sim reset" often enough would eventually completely block/
overload the system.
Need to clear the engine list before appending a new set of engines.
Engine list was growing on every FDM reset, causing weird control effects
after (multiple) sim resets.
Use --prop:/sim/rendering/shaders/quality-level=-1 to enable the custom
settings in the Shader Options dialog.
Apart from that the quality-level property will work as before (0 disables
all shaders, 5 puts all shaders to max.
