Generally you want point sprites for performance reasons when enhanced runway
lighting (and smooth points) are activated. Most hardware doesn't
accelerate the rendering of standard smooth points, so without point sprites
you will kill your night time performance if you turn on enhanced runway
lighting.
Note that enhanced runway lighting "breaks" our clever scheme to make the
runway lighting brightness vary with the relative view angle. This means
with enhanced lighting on, all lights are equally bright no matter what
direction you view them from. So perpendicular runways are just as bright
as runways you are directly lined up with (when enhanced runway lighthing
is activated.)
You can revert to the original lighting scheme by turning off enhance runway
lights, turning off distance-attenuation, and turning off point-sprites in
the rendering options menu.
maintainable. The rules are simple (extension functions are called
*with* the lock, which must be dropped before calling naCall(), which
grabs it) but the tracking of when the lock was held was getting a
little confused. Keep a "nasal call depth" count in the subsystem to
figure out whether we are making a sub-call and thus hold the lock.

I attach 2 new files and a diff file for the associated changes to add a
“fluxgate compass” to the instrument inventory. Whist this outputs
essentially the same data as /orientation/heading-magnetic-deg, it has to
be powered, and can be made to fail. I also followed Roy’s suggestion to
generate the error properties for this instrument here rather than in
xmlauto.xml.
When this instrument is included in cvs, I intend to use it in the Hunter,
A4F Seahawk and KC135. After a bit more research, it might be appropriate
for the Spitfire and Hurricane as well. AJ would also like to use it for his

is reported correctly in the entity's property subtree.
- In AIMultiplayer.cxx, compute a velocity value in kts to fill in the speed

This patch switches to a much more sane method for ground track computation.
Thanks to tied functions, this is only executed when the node is read. This
will be done by the old & new HUD code, the latter of which won't have a
special lon/lat mode at all. Instead it will be regular labels that point

basically the same thing), and to avoid using static buffers and all, but

fly with. They proceed on in "freeflight" mode indefinitely. For example,
there is a refueling demo where the tanker starts at 3000', 280 kts, and
in a 15 degree bank, and then continues to orbit indefinitely.
For these aircraft with no flightplan, I have added several control nodes in
controls/flight that allow a script or menu or external application to set

or scripted control over AI aircraft.

Here is one patch that to make FlightGear run without floating point

When AIFlightPlanCreateTaxi() function is called with the firstFlight
argument set to true, this is supposed to handle situations where the
the aircraft's timetable indicates it should have left between about 5 to
20 minutes earlier. In the previous version, all these aircraft started
taxiing from the first parking location available in the network, due
to the fact that the variable gateId was not assigned a value. In this
patch, route tracing starts from an assigned gate and the network node
following code is fast forwarded to a random location along the taxiways
to give a more realistic and natural distribution of taxiing aircraft
after startup.
This patch further addresses some weird ballet-dancing behavior that
aircraft were showing just prior to/right after parking and which was
related to a number of more or less duplicate waypoints in the transition
from createTaxi() to createParking() to createPushBack() to createTaxi().
Finally, a blatant typing error in the getParking() function was fixed.
at (lon, lat) coordinates -1000,0. This patch fixes the AIModels/Traffic
Manager side of things. The AIModels subsystems allowed the creation of
AIAircraft with non-existent 3D models. If such a model didn't exist, the
aip class didn't get initialized, resulting in the above-mentioned bogus
position information. Here I circumvent this problem by a) only interacting
with the tile loader if the model is visible (and hence has succesfully been
initialized) and b) by disallowing the traffic manager to create AIAircraft
objects if the path to the 3D model doesn't exist.

I am attaching a trivial patch that changes the normalization from 24 to

indicator spin value in the property tree of 0.9996 and the same value
for the pa28-161 is 1.0, so there is no harm to a 24 volt electrical
system in this change. Should the battery or alternator put out a lower
voltage than 12 volts, the spin value goes down and the tc shows a
negative turn that increases as the voltage gets less. This file shows
you as the author. If you are comfortable with this change, commit it
to cvs and the tc will be correct even for 12 volt systems.

the carrier to match the usual ones. I believed that I had done so, but it
was definitly different. Also there are more parking positions avaliable now.
The new multiplayer patch with an extension to transmit some properties with
the base package. The properties are transmitted in a way that will not
immediately brake the packet format if we need new ones.
Even if the maxmimum number needs to be limited somehow, that format might
work well until we have an improoved packet format which is even more compact
and that does not require to retransmit redundant information with each
packet.
That part is relatively fresh and based on that what Oliver provides on his
multiplayer server web page.
The properties are transferred to the client and I have modified the seahawks
rudder animation property to use a relative property path to verify that it
works appart from the fact that you can see it changing in the property
browser.
The movement is still a bit jerky, but that can be fixed/tuned later without
again braking the packet format.
This patch makes FlightGear at least compile on MSVC. I hope I have removed

the viewpoint when the mouse jumps to another side of the screen.
Right now, the mouse is constrained to stay between 25% and 75% of the
screen on both the X and Y axis -- whenever it hits an edge, it jumps
back to the centre of the screen again (which causes no control or
view jump).

can't go to $FG_ROOT (due to permissions and clean separation of 'official'
data and local modifications)
right corner, not those that are result of centering a dialog if no x/y are
given. This centers screen.log messages correctly. But maybe we have to
rethink that special meaning of negative coords altogether.
This patch removes some useless indirection when creating AIModels. It
obsolets AIScenario*.
AIEntities are just an intermediate copy of an other intermediate copy of an
xml file on the way from the ai scenario configuration file to the AIModels.
As such the AImodels can now be created directly from the property tree read
from the scenario file.
This reduces the amount of work needed to add an other AIModel and reduces the
amount of copy operations done during initialization.
It also moves internal knowledge of special AI models into these special AI
models class instead of spreading that into the whole AIModel subdirectory
which in turn enables to use carrier internal data structures for carrier
internal data ...
Also some unused variables are removed from the AIModel classes.
I believe that there are still more of them, but that is what I stumbled
accross ...
Tested, like the other splitouts these days in a seperate tree and using the
autopilot for some time, and in this case with a carrier start ...
problems because a lot of people already have their *real* preferences
set in ~/.fgfs/preferences.xml (and don't want fgfs to stomp over them),
because the name doesn't tell people that their data aren't save there
(comments!), and because this is inconsistent with the global preferences.xml
file, where user changes *are* respected.
This patch is a combined effort by Gregor Richards, Oliver Schroeder, and
Vivian Meazza (and code cleanups and improvements by Erik Hofman). It corrects
the bug in which a Multiplayer model responds to local inputs, and the view
number bug which caused certain aircraft to appear as cockpit only models. It
passes remote properties over the net, and all major control surfaces and gear
are now animated correctly, providing that the local ~model.xml file contains
no leading "/" in the <property></property> data entries. MP objects
are now extrapolated using 1st and 2nd derivatives to make their movement
appear more smooth. The sim is now halted while a new client joins the net.
Known problems with MP are non-display of the remote client under certain
circumstances of starting/resetting, and a freeze on starting. These bugs are
long standing, and are not addressed by this patch.
Special thanks must go to AJ Macleod for his patient testing of this patch over many evenings.
We have also moved part of multiplayer into AIModels as part of the ongoing
development of MP.
because a dialog button can get pressed when its callback isn't available
any more. Ideally, we would close the dialog or update its buttons when
this happens. But this requires bigger changes.
/sim/messages/{atc,pilot,ai-plane,ground,approach}
These can the be used for differenct screen.log colors and for different
voices. (Aircraft & tutoruals may want to write to /sim/messages/copilot)
Fix the current buggy rain orientation behaviour for the views attached to the
aircraft (while still inheriting bugs with the views attached to anything else).
I had massive problems with tower.cxx, so I decided to doublecheck all
containers and iterators in order and found lot of potential problems.
Now I can fly with "debug on" of KSFO for minutes without problems.
The fix for AIMgr is from Mathias, but I reworked it. So blame me, not him.
- Feet to meter conversion mistake (in AI getGround elev)
- Improved ground following code (not yet perfect, but for now no one will
notice it within the marginal altitiude differences at the taxitrack or
runway)
- Exclusion of the "AI" directory witihin data/Aircraft in
main/init/fgSearchAircraft, to prevent AI aircraft to be picked up by the
aircraft search function

The attached patch fixes this problem.
This patch limits the maximum simtime we do simulation computations for.
That is highly sensible if you run flightgear in valgrind or some realy slow
debug build. In such a case it is possible that flightgear gets totally
unresponsible, because simulation time might increase slower than real time.
That patch introduces a maximum simulation time per rendered frame to limit
that effect.
If the property /sim/max-simtime-per-frame is set to something strictly
positive, the simulation time is limited to that value.
The default is unchanged - no limit.
Anyway, from the point of view of gui responsiveness and responsiveness to
realtime controls like joystick inputs it might be a good idea to limit that
by default to say 1 second. If you have less than 1fps, flightgear is
unplayable anyway and I believe we do not longer need to care for realtime
correctness for that case ...
though the window wasn't resized. I'm just not adventurous enough for
a cleaner solution in the light of the upcoming release. At least the
xsize/ysize properties aren't set each frame any more, so listeners
work now properly.
