Here's an unusual patch for FlightGear -- I've created .cvsignore
files for every source directory, to make CVS output more informative.
This is especially nice when using cvs-examine from (X)Emacs to look
for changes.
a top level aircraft def file (c172-set.xml)
preferences.xml or --aircraft= or any other property setting mechanism can
be used to set the property "/sim/aircraft". After all options and config
files are parsed, the contents of /sim/aircraft is expanded into a *-set.xml
file and loaded.
- delete table in destructor
** src/FDM/flight.cxx
- bind engine properties in FGInterface::bind, and publish properties
for all engines rather than just engine 0
** src/Main/fg_props.cxx
- removed all engine properties; now bound in FGInterface::bind
** src/Sounds/fg_fx.cxx
- support multiple engine and cranking sounds
** src/Sounds/fg_fx.hxx
- support multiple engine and cranking sounds
to control logging
- /sim/logging/classes takes a value like "terrain|astro", where the
names are the macros from simgear/debug/debug_types.h with the
initial "SG_" removed and converted to lower case; for none, use
"none"
- /sim/logging/priority takes a single name like "warn", where the
name is a macro from simgear/debug/debug_types.h with the initial
"SG_" removed and converted to lower case
fix startup sequence problems where we initialize the FDM before we know
the desired starting altitude.
These changes delay fdm initialization until the local tile has been loaded
and we can do a real intersection and find the true ground elevation.
In order to do this, I depend more on the property manager as glue, rather
than the FGInterface.
There are some glitches still when switching to a new airport or reseting
the sim. I will work on addressing these, but I need to commit the changes
so far to keep in sync with other developers.
meaning of "win_ratio". I've removed win_ratio and added fov_ratio and
aspect_ratio, as it seems both are needed.
n.b. The multi-line changes in fgReshape comprise:
extracting common code,
removing an apparently arbitrary "+1" on the view height,
changing "set_win_ratio" to "set_aspect_ratio".
through the controls interface and the running and cranking flags through
the engine interface. This has no current effect on LaRCsim (other than
to make the code neater) but is necessary to add engine startup to JSBSim
which is now underway. I've also put in main.cxx which escaped getting
committed in the previous round of changes - adding this will add
the cranking sound to LaRCsim during engine startup.
one I sent yesterday. I have re-zipped all four files so you can
neglect the last lot but only io360.cxx has changed if you've
already committed. It's untested since I can't start the engine until
John has committed his update with separate properties. Should
work fine though.
- use guiErrorMessage
- added new properties /sim/view/pilot/x-offset-m,
/sim/view/pilot/y-offset-m, and /sim/view/pilot/z-offset-m to
control pilot-position offset from CG
I've updated the WeatherDatabase to be able to use only the n closest
stations. This can speed up the initalization dramatically.
To take a benefit from that you need:
- http://129.13.102.67/out/flight/current.txt.gz in
FG_ROOT/weather/current.txt.gz
- --prop:/environment/weather/working-type=internet
- --prop:/environment/weather/max-stations=what_ever_you_want
The WeatherCM stuff now publishes its data in the property system.
/environment/weather/wind-north-mps
/environment/weather/wind-east-mps
/environment/weather/wind-up-mps
/environment/weather/temperature-K
/environment/weather/air-pressure-Pa
/environment/weather/vapor-pressure-Pa
/environment/weather/air-density
are the new properties.
