- include Input/input.hxx
- register GLUTkeyup and GLUTspecialkeyup with glut
- comment out call to fgJoystickRead
- comment out call to fgJoystickInit
- add call to FGInput::update to replace fgJoystickRead
Fixed a few glitches in the autopilot keys
Added a #define to be able to make a compile time decision to revert to
older GPS like autopiolt behavior this define SHOULD become a property
so that it is run time switchable.
(src/Input). So far, FGInput replaces most of src/Main/keyboard.cxx
(I've left a tiny stub); in the very near future, it will also take
over control of the joystick, mouse (Norm permitting), and panel
instrument interactions, so that there is a single mechanism for
configuring all input devices.
The new format should be (close to) self-explanatory by looking at the
new base-package file keyboard.xml, which is now included by
preferences.xml (I'll do the same thing for the joystick when I have a
chance). I have not managed to move all keybindings into this file
yet, but I've made a good start. I'm including Tony in the recipient
list so that he can see how bindings can use an external XML file.
This patch also adds support for multiple bindings for a single key,
special keys (i.e. keypad and function keys), and key modifiers
(shift/alt/ctrl); special keys use the PUI convention of adding 256 to
the Glut key code.
Unfortunately, everything comes with a price; in this case, I have not
yet found a general mechanism for the old (hard-coded) modal bindings,
which behaved differently depending on the autopilot state (i.e. left
rudder or move AP heading left); with my patches, this functionality
disappears, but you can still adjust the autopilot using the panel or
the GUI input dialogs.
- model loading deferred to primary thread
- tile removal deferred to paging thread
- other tweaks and rearrangments.
Airport signs
- first stab at some support for adding taxiway and runway signs. This
is non-optimal, but I'm under the gun for a demo.

Here are the final changes to add threads to the tile loading. All the
thread related code is in the new FGTileLoader class.
./configure.in
./acconfig.h
Added --with-threads option and corresponding ENABLE_THREADS
definition. The default is no threads.
./src/Scenery/tilemgr
Removed load_queue and associated references. This has been replaced by
a new class FGTileLoader in FGNewCache.
Made the global variable global_tile_cache a member.
schedule_needed(): removed global_tile_cache.exists() tests since
sched_tile() effectively repeats the test.
initialize_queue(): removed code that loads tiles since this is now
performed by FGTileLoader.
update(): ditto
./src/Scenery/newcache
Added new class FGTileLoader to manage tile queuing and loading.
tile_map typedefs are private.
exists() is a const member function.
fill_in(): deleted
load_tile(): added.
./src/Scenery/FGTileLoader
The new threaded tile loader. Maintains a queue of tiles waiting to be
loaded and an array of one or more threads to load the tiles. Currently
only a single thread is created. The queue is guarded by a mutex to
synchronize access. A condition variable signals the thread when the
queue is non-empty.
CLO: I made a few tweaks to address a couple issues, hopefully what we
have is solid, but now we kick it out to the general public to see. :-)
The files in the attached tarball make the following changes to
FlightGear:
- rename the existing FGInterface::init() method to
FGInterface::_setup to get it out of the way
- move *all* FDM initialization code out of src/Main/fg_init.cxx and
into FGInterface::init(), and clean up fg_init.cxx a little
(especially by removing the zillions of attempts to place the plane on
the ground at various locations in the code)
- modify FGInterface::bind() so that no values are picked up
automatically at bind time (they are set previously by init() instead)
- modify the init() methods of the classes derived from FGInterface
(i.e. larcsim, jsbsim, balloon, magic, and ada) to invoke
FGInterface::init() explicitly before doing their own setup
I don't claim that the code in FGInterface::init() is optimal (or even
correct), but it seems to work for on-ground starts with both LaRCSim
and JSBSim on runways pointing various directions from near sea level
to about 700' ASL (the range I happened to test). I expect that Jon
and Tony will want to look at the code and refactor and correct it now
that they can see what's going on in one place.
Here's a quick outline of what is invoked:
cur_fdm_state = new <whatever>(dt);
cur_fdm_state->init();
cur_fdm_state->bind();
The constructor allocates memory and sets default values only (with
the help of the FGInterface::_setup() method). The init() method pull
any required properties out of the property tree and sets up the
initial state of the FDM. The bind() method takes ownership of
FDM-related properties so that the FDM can publish them to the rest of
the sim.
Note that bind() and init() are virtual, so any implementation in a
subclass will hide the implementation in FGInterface; that's why
subclass implementations of init() and bind() have to invoke
FGInterface::init() and FGInterface::bind() explicitly, probably at
the start, so that they get the basic initialization.
hope, with earlier versions as well)
- support for the new LONG value type
- gear support for UIUC (updated for the newly renamed SG_* stuff;
otherwise identical to what I sent you before)
- fixed reported MSVC problem in src/FDM/flight.cxx
a) I was compairing feet vs. meter (making the range 3x too. big)
b) I was using the diameter in place of the radius (making the range an
additional 2x too big.)
c) Updated the equation for calculating range to model the weak transmitter
not being picked up at upper altitudes.
We still might need some additional tweaking, but I think we are starting to
get in the right ball park.
is 9 not 8.) Note that the initial altitude setting was placing us way below
the ground, but as it doesn't seem to have caused us problems, it's probably
redundant!
