One thing I maybe should add to the doc is that the order of operation is
always:
1. scale (multiplication)
2. offset (addition)
3. truncate (truncation)
This will matter when, for instance, converting from Fahrenheit to Celsius.
The normal formula is C = (F - 32) * 0.55555556. The operator precedence
above requires a new formula, C = (F * 0.555555556) - 17.777777777.
controls in the cockpit vs. which wheels they apply to. FlightGear now
sets /controls/gear/brake-left, /controls/gear/brake-right, and
/controls/gear/brake-parking. It should be up to the FDM to sort out
which wheels under which circumstances are affected by these controls
and ultimately what happens to the physical motion of the aircraft.
First, I've attached a copy of the Logitech WingMan Force 3D XML
file "wingman-force-3d.xml" I put together after getting one of
these for Christmas. (It would be nice if the force feedback worked,
but I haven't had time to play with it that much. Come to think about
it I'm not even sure forece feedback works under Linux in general.)
Besides providing the new file I also edited the higher-level
/FlightGear/joysticks.xml file to add the description for this joystick
as follows:
diff -n joysticks.xml_orig joysticks.xml
a22 1
<js-named include="Input/Joysticks/Logitech/wingman-force-3d.xml"/>
/sim/input/selected/engine[n] properties. Also, new properties get
empty string values (which are boolean true in Nasal, maybe that
should be changed?), so test for numeric truth.
Move the "tip popup" code from view.nas to a new gui.nas module, and
make it generically useful.
Wire up flap steppings for the 747 as an example of per-aircraft
flaps.
Realtime-based property slewing, to eliminate dependence of trim and
view direction rates on frame rate.
New Node.setValues() method which sets whole property trees from Nasal
data.
A view.nas module, which takes over handling of the X/x zoom keys. It
clamps the FOV to a dynamically calculated maximum corresponding to
typical human visual accuity, and pops up a pretty dialog informing
you of the new FOV.
Make a new set location (on ground) dialog box which knows how to set up
the /sim/presets/ properties correctly for a new ground position.
For now leave the previous all-in-one dialog box for in-air resets. However
this really needs some more work to make sure the /sim/presets properties get
set correctly.
Remove the broken yellow lines around the taxiways. They're rare in
real life, and look awful in FlightGear, since we cannot really align
taxiways yet anyway.
I'm using a different Joystick now, but these changes
were on my harddisk for a while and should be in CVS:
replace "squared" by "power 3" (the X8-30 is of rather
bad quality, and the 3 help to avoid jitter). Add
"interval-sec" settings.
