newauto.cxx. Basically everything is the same functionally except for a
changed in the initial altitude setting to 3000ft instead of meters (the panel
is in feet).
and scaling of control values to properties. Also added a time interpolation
feature that replaces the hacked-in "retract-time" feature for the gear in
a more general way (applicable to flaps, too!). Incompatibly breaks
the XML syntax; get new files!
individual aircraft to have different sounds (and cleaning up my code
a fair bit). The most important user-visible change is the renaming
of the /sim/sound property to /sim/sound/audible.
(other than "none") is "spin", which must be tied to a property giving
a value in RPM. This gets the DC-3 propellers turning. The next type
will be "rotation", which will allow the flaps, elevators, ailerons,
and rudders to move (and even gear, eventually). Later, I'll add
"shift" for sliding things around, and will figure something out for
blinking lights.
the XML file, including the path to the 3D file.
This change obsoletes the existing /sim/model/*-offset-deg and
/sim/model/*-offset-m properties in the main property tree, and
replaces them with /offsets/*-deg and /offsets/*-m in the model
property file. The /path property in the model XML file is relative
to the XML file's location rather than FG_ROOT.
Added two new properties:
/environment/temperature-sea-level-degc
/environment/pressure-sea-level-inhg
These are now supported in FGEnvironment as well, though they always
have the same value for now. They need to be hooked up to the FDMs.
different locations, and hitched it into FGGlobals. FGEnvironmentMgr
has taken over as the subsystem, while FGEnvironment is simple the
information that it returns. I've removed current_environment
completely -- everything now uses properties or goes through
FGGlobals. FGGlobals itself has a couple of useful methods:
const FGEnvironment * get_environment ();
const FGEnvironment * get_environment (double lat, double lon, double alt);
The first one returns the environment data for the plane's current
position, while the second returns the environment data for any
arbitrary location. Currently, they both return the same information,
but that will change soon.
properties have been renamed from wind-(north|east|down)-fps to
wind-from-(north|east|down)-fps, and the FDMs modified appropriately.
No other changes should be visible unless FG_OLD_WEATHER is defined.
Attached are patches for adding the command line options to set initial
glideslope and climb rate. This was really easy to do as all the pieces
were in place. It works well with JSBSim because the trimming routine
finds the right throttle and elevator settings. It should work with
LaRCsim as well, but it has no trimming routine so there will be some
dynamics at startup. I don't know what YASim will do.
the panel controls for the autopilot. The heading dialog would only show the
last setting you did through it, even if it was later tweaked with the bug on
the hsi. The altitude dialog did a similar thing. Now the values default to
the same that show on the panel displays.
via the command line (--enable-clock-freeze / --disable-clock-freeze)
and can be toggled during a run. However this property is not currently
bound to any menu or keystroke so you have to do it via the gui property
interface or externally via the web property browser or a script.

Akso found and fixed a bug in the simgear that caused the time to go goofy
temporarily while scenery was being loaded.
as well as visibility.
This means that if you are using this protocal to exchange data with a
visual channel, you should be able to change time and visibility on the master
and all the slaved visual channels will match it.
Attached is a fix to add a short period of cranking time required
before the engine fires. I've also added a little hack to limit the
torque applied by the starter motor when the rpm is less than 10 in
order to avoid the rpm overshooting idle in the first time step when
the prop is producing very little resistance due to the low rpm.
- remove buffer with class scope
- remove variable 'length' (isn't used anywhere)
- make process_command private (it isn't used anywhere outside, and it
shouldn't be)
- define buffers where they are needed (two places)
- comment out stale debug message (it doesn't buy anything, because the
contents are output two lines below, anyway)
- let every error message begin with "ERR ". This makes error messages
less beautiful, but easier to recognize for scripts. Every internet
protocol that outputs text, has such a tag for distinguishing regular
output from error messages. (pop3 uses "-ERR ", smtp uses error codes,
etc.)
- fix html bug (<form> was closed by another <form>, instead of </form>)
- remove useless <br>
- fix a bug, that would have truncated an argument containing a '&'
- extend the comment for urlEncode: cite the concerned RFC
max(width, height) by default (easily changeable) rather than just width.

This works on a CygWin build, and probably works on non-Cygwin builds
as well.
2. Enable FG to start even if audio is not available. (soundmgr.cxx)
Avoids the FGSoundMgr constructor crashing; the rest of FG then runs
OK without sound.
1. Enable auto-configure on more versions of auto tools. (configure.in)
2. Warnings from auto-configure tools. (src/Time/Makefile.am)
3. Typo: "the it's" -> "its". (docs-mini/README.Joystick)
4. Remove definition of FGViewer::update() that now is (or can be) pure

5. Preferred form of function name according to comments in plib:

-> "notWorking". (src/Sound/soundmgr.hxx)
format before reading/writing data from/to remote machine. This allows
different endian machines to talk to each other. Also added support for
passing time and time offset (warp) in the data packet.
I've attached 3 diffs against files in FlightGear to fix some printf
format strings. The changes are pretty straight forward. Let me know
if you have any questions. (BTW, I'm using gcc 2.95.4)
/sim/freeze/master (implimented)
/sim/freeze/fuel (implimented)
/sim/freeze/position (not implimented)
/sim/freeze/time-of-day (not implimented)
/sim/freeze/master is bound to the 'p' key via keyboard.xml, however,
/sim/freeze/fuel is not bound to anything at the moment so you must
change it via the external property interface, or specify an initial
value on the command line.
properties /sim/view/view-tilt-deg and /sim/view/goal-view-tilt-deg
control the tilt. There are (temporarily) keyboard bindings in the
base package for experimentation: Ctrl-O to tilt the view down, and
Ctrl-P to tilt the view up.
otherwise, the logic in FGEngine::ConsumeFuel breaks down and the
engine is starved when *any* feed tank is empty, rather than when all
feed tanks are empty.
FDM people. FlightGear now supports an unlimited number of fuel
tanks. Also added correct fuel-flow reporting for piston engines, and
tracked new features in SimGear property support.
other -- it is now possible to set properties at startup (such as an
autopilot altitude). The only user-visible change, other than the
fact that the properties work as they are supposed to, is that the
heading bug no longer starts at a random value.
function to allow property files as non-option parameters after the
options have finished (and added "--" to terminate options). It's now
possible to do something like
fgfs denver-am.fgd
or even
fgfs at-lax.fgd in-c310.fgd around-sunset.fgd
This works the same way as the --config option, but will be friendlier
for GUIs, where start-up situation files can now be associated easily
with FlightGear.
Changed _set_Accels_Pilot_Body to use FGAuxiliary::GetNpilot instead
of FGAuxiliary::GetPilotAccel. It looks like a similar change was
started but never finished, and there are artifacts still lingering.
With this change, the slip/skid ball now works reasonably on the C172
when in motion, but not at rest (that will have to wait for fixes to
the gear code).
material-specific logic is now removed from the material library and
encapsulated in the material class itself, and materials are loaded
from $FG_ROOT/materials.xml rather than $FG_ROOT/materials. This also
removes a nasty bug in the old material-loading code that caused a
floating-point exception.
- automake-1.4 sets default values for INCLUDES which we can't
overwrite.
- automake-1.5 renames this to DEFAULT_INCLUDES and leaves INCLUDES
open for the developer to use.
Thus for automake-1.4 we are forced to 'append' to INCLUDES and in
automake-1.5 we can just set the value to whatever we like.
Unfortunately, the behaviors of the two versions are mutually
incompatible.
The solution I am committing now works for both versions but
automake-1.5 generates a lot of spurious warning messages that are
annoying, but not fatal.

eventually, it will allow all subsystems to update by time rather than
by framerate.
beginning of main() for the exceptions that can be enabled (only
divide-by-zero is enabled by default, but you can uncomment any ones
you want); eventually, FlightGear should run cleanly with all FPEs

has absolutely no bearing on actual wheel performance and has nothing to do
with the fdm. It is just a simplistic wheel spin velocity model used to
avoid subsequent squealing when a tire is bouncing, or touches down right after lifting off. If at some point tire spin is modeled by an FDM we could
transition to using real data.
FGInterface::_updateGeocentricPosition() for clarity. Also added an
FGInterface::_updateGeodeticPosition() since it is useful.
A few clean ups to native_fdm.cxx and raw_fdm.hxx.
These will log trace messages whenever a specific property value is
read or written through the property manager. They do not cause
FlightGear to poll bound values, so if a class variable that is bound
is changed directly, no trace message will be displayed.
These options are also useful in conjunction with a debugger.
--trace-read will cause the private SimGear SGPropertyNode::trace_read
method to be invoked, and --trace-write will cause the private SimGear
SGPropertyNode::trace_write method to be invoked; in a debugger
session, a user can set breakpoints on these methods then get a
backtrace to see what specific points in the code are reading or
writing properties.
