"slow/windmilling propeller" regime. I'm happy with the foundations
of the solution, but this hasn't been complete tested yet. The
solution behavior seems fine on the planes I tried.
PistonEngine class has grown an "Engine" superclass. Some other stuff
moved around too, and I cleaned up some property naming while I was in
there. This hasn't been tested very thorougly, hopefully I didn't
break anything.
configure and compile out-of-the-box on a MinGW target:
Use -lSDL instead of -lglut32 on windows builds when --enable-sdl
is set.
Link against alut.dll in addition to openal32.dll.
Replace BSD bcopy() with ANSI C memmove() in a few places. This is
simpler than trying to abstract it out as a platform dependency in a
header file; bcopy() has never been standard.
The ENABLE_THREADS handling has changed to be set to 0 when threads
are not in use. This breaks expressions like #ifdef ENABLE_THREADS.
Replace with a slightly more complicated expression. It might have
been better to fix the configure.ac script, but I didn't know how and
this whole setting is likely to go away soon anyway.
The MinGW C runtime actually does include snprintf, so only MSVC
builds (and not all WIN32 ones) need _snprintf in JSBSim/FGState.cpp
Building on a platform with no glut at all exposed some spots where
plib/pu.h was being included without a toolkit setting (it defaults to
glut). Include fg_os.hxx first.
And when still using glut, glut.h has a bizarre dependency on a
_WCHAR_T_DEFINED symbol. It it's not defined, it tries to redefine
(!!) wchar_t to disasterous effect.
anymore. Instead Frederic Bouvier suggests to add a <number> tag to
the axis definition which accepts values for <windows> and <unix>
for now but which can be extended later on:
<axis>
<desc>Rudder</desc>
<number>
<unix>2</unix>
<windows>3</windows>
</number>
<binding>
<command>property-scale</command>
<property>/controls/flight/rudder</property>
<offset type="double">0.0</offset>
<factor type="double">1.0</factor>
<power type="double">2.0</power>
</binding>
</axis>
1. The listener is always positioned at the origin.
2. All sounds eminate from the aircraft's model position.
3. Sound positions are relative to the listener location.
I've added a tracking bug to the gps. This is of course very similar to a
heading bug for a DG. I don't know if this is the common name, but I feel
that for a gps the name tracking bug is more accurate than heading bug. A
true bug error and a magnetic bug error is calculated and shifted into the
-180 to 180 range so that they can be used by autopilots.
I've also fixed a property name that crept in when I had to change back to
indicated-***. Back then I accidentally changed the desired course name to
"indicated-course". The property that is supposed to be the input for the
desired course should naturally be named something like "desired-course", and
definitely _not_ "indicated-course". If this name change breaks anything it
should be fixed in the other end.
I've also commented out a lot of #includes that I don't think is needed. I'm
on Suse 9.0 now, and it builds fine here, but this might be a problem for
different platforms I guess we have to cross our fingers.
my code was accidentally drawing the cockpit twice
in view 0. This patch should fix the problem of
lights not seen through canopies or prop discs.
It was also drawing the lights ( ground and rw )
after the clouds, so they were not obscured by
them.
command bindings accessible from XML. This still probably isn't a final
solution (which would drive the HUD from propery values), but it's a step
in the right direction anyway.
