two almost identical functions for these methods. It only forces to repeat
the redundancy for every small change to either.
- abstract out generation and destruction of plib string arrays
- abstract out generation of lists from <value> children
- only call globals->set_initial_waypoints() if the waypoints list address
has actually changed, that is: if it has just been initialized
- remove trailing spaces
- fix indentation
but got changed so that Nasal listeners wouldn't be triggered needlessly.
Doesn't make sense, though, as Nasal will never be available before the
video size is set, and it prevents the window interface from setting the
startup size.)
Here is one patch that to make FlightGear run without floating point
exceptions on FreeBSD. Apparently, if we do not ignore floating point
exceptions per this patch, there is some occasional condition where the
nvidia driver is involved in delivering spurious floating point exceptions
to the fgfs process, causing it to core-dump occasionally without the patch.
With only this patch, FlightGear will compile and run properly on
FreeBSD 6.X as long as the nvidia accelerated driver is installed,
modulo proper switches to the SimGear and FlightGear configure script
executions.
Again, kudos to your team for the great work on the big release
push; it is super to see things come together like this!
a race condition ending in warping twice and having huge increments for the
second warp.
I am not aware of such a flush function in glut. So we emulate that by
ignoring mouse move events between a warp mouse and the next frame.
That should make glut behavour aequivalent to sdl behavour.
I have implemented a Honeywell MK VIII EGPWS emulation for FlightGear.
The MK VIII is an Enhanced Ground Proximity Warning System aimed at
regional turboprop and small turbofan aircrafts such as the Citation,
Citation Bravo, B1900D, Beechcraft 99 and L410.
Frederic Bouvier:
make the MSVC compilation possible. Rearrange base package directories.
This patch makes use of the vectors now available in simgear with that past
patch. And using that it simplyfies the carrier code somehow.
- Small additional factory's to the quaternion code are done in the simgear
part. Also more explicit unit names in the factory functions.
- The flightgear part makes use of them and simplyfies some computations
especially in the carrier code.
- The data part fixes the coordinate frames I used for the park positions in
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.
the mouse pointer to a new position. Otherwise it can happen that the new
position is first set, but then come a few still unprocessed events for the
old position. This makes ugly jumps in mouse view mode.

implementation turns out to be too slow, we'll write a generic OpenGL/plib
version simliar to the ATCdisplay code. (OK'ed by Andy and Stuart)

scripts that load/write user specific data that shouldn't go to PWD, and

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.
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).
- 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
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.
Erik Hofman:
This patch contains an update to net_ctrls.hxx that adds an extra 100 bytes
(or an equivalent of 25 (u)int32_t types) of reserved space. This could be
used to make the protocol forward and backward compatibel within a certain
scope. Be sure to read the instructions at the begining of the header file
when addinf new variables.
"play-audio-function" command. This function can be called from internal
code, from nasal scripts, or from external scripts to play a single one-off
wav file. File/audio data is loaded and unloaded on the fly automatically.
- Provide a Nasal interface to display simple text messages on the screen
like the ATC display. In fact, I copied the code from the ATCDisplay.cxx
and simply shifted it further down the screen.

TODO: Integrate the two pieces of code.
Computes the pick direction and starting point. This is code that translates
a screen coordinate into a vector in the FlightGear world (between the eye and
the on-screen coordinate.) Armed with this vector in FG world coordinates,
you could call a scenery intersection routine and lookup the lon/lat/elev of
the point in the world that was clicked on.
* in some cases more specific sg exception types were used in place
of the more generic one, e.g., sg_io_exception instead of sg_exception
when the context of the error was an IO error
* in some cases, the error message was made more specific
* minor style fix for exception rethrowing --- using throw; whenever
a re-throw is made; sometimes optimizing away the exception symbol name
in the catch handler at all
* more specific catch handlers added in some places -- e.g.,
an sg_io_exception caught ahead of sg_exception
Insert empty string as marker between FG_SCENERY path elements.
FG_SCENERY=A:B expands to [A/Terrain, A/Objects, "", B/Terrain, B/Objects, ""]
(assuming that both A/ and B/ have Terrain/ and Objects/ subdirs).
tileentry.cxx -- FGTileEntry::load():
Check all tile dirs in FG_SCENERY from left to right: add all objects
to the scenery until a terrain tile was found: In this case read the
rest of that group (i.e. the Objects/ twin dir) and then stop scanning.
Better structuring of log messages & fix warnings.
to pop themselves down while the simulator is paused.
The problem was with the "real time" queue in the event manager,
causing the third argument of Nasal's settimer() (a flag for "sim
time") to be ignored. Inverts the default sense of the argument, as
there are lots of uses of settimer() in the current code, almost none
of which want to use real time.
Note this fix introduces a header file incompatibility in SimGear --
be sure to update.
redraw(): redraw gui without distroying dialogs (fgcommand "gui-redaw"/Shift-F10)
This change makes sure that Nasal-generated and dynamic dialogs can be
re-opened correctly when cycling through themes.
there was the situation where four directories contained jst two files,
of which three directories were aircraft related, and one directory contained
test code from Curt that might be better of in SimGear anyhow.
This is just a patch to move a bunch of files to new locations. In case of
local changes to any of them you can do the following:
move replay.[ch]xx from src/Replay to src/Aircraft
move control.[ch]xx from src/Control to src/Aircraft
move ssgEntityArray.[ch]xx from src/Objects to simgear/screen
In addition it has been decided only to use .[ch]xx files in all directories
unless it's contained within an FDM specific directory, in which case the
author is free to do whatever (s)he wants.
In this repspect the following files have been renamed in src/Multiplayer:
tiny_xdr.[ch]pp has become tiny_xdr.[ch]xx
multiplaymgr.[ch]pp has become multiplaymgr.[ch]xx
