where it is desirable (it defaults to false); the <key>'s <repeatable>
setting is also used for the <mod-shift> branch, so we have to set it
as soon as one branch needs it.
Changes
=======
New volumetric shadows for FlightGear.
There is now two new checkboxes in the rendering dialog to enable/disable shadows
for the user aircraft and for static scenery objects (ie those defined in the .stg files).
AI and random objects are not handled for the moment.
known bugs
==========
- ghost objects
- to support "old-style" gear/flap control (operation as long as button
pressed/lever pushed -> b29/hurricane), let bindings not only report
up/down, but up (-1), stop (0), down (1).
- let controls.flapsDown() ignore "stop" so as to remain compatible with
prior behavior
- adapt all joysticks/aircraft (sigh)
- some minor cosmetics in joystick configs, such as indentation fixes
avoids the obscure and ugly "which" workaround
Note that the input subsystem sets variable "this" to this joystick's
base property path; This is useful to be able to access the driver's own
information from the property tree. Example:
data = props.globals.getNode(this).getNode("data");
where "this" contains string "/input[0]/joysticks[0]/js[0]" if the js is
the first in the system
for operation-modes; only one user visible change: the speed brake toggle
does now also show a popup like the thrust reverser and the parking brake;
I hope that this is seen as useful help rather than annoyance.
1) The AIStorm sets the properties:
/environment/turbulence/magnitude-norm
/environment/turbulence/rate-hz
The actual turbulence effects are handled by the FDM.
If the effects are deemed unrealistic, then that will
have to be fixed in the FDM(s).
2) The zone of turbulence is cylindrical, and is centered
at the AIStorm's lat/lon. The diameter is set with
<diameter-ft>, the top with <height-msl>, the bottom is
assumed to be at <altitude> minus 1000 feet.
3) Note that the zone of turbulence may not match well with
the visual model of the storm. In this case I had to
x-offset the storm model by 4700 meters to match the zone
of turbulence. (i.e. the storm model is 4700m off center).
4) While I was in there I also increased the speed of the
lightning flashes to look more realistic.
This is another update for the cloud code, a lot of lines but this time I have started to add the doxygen doc.
Misc
====
- corrected a bug when RTT is not available, the current rendering context was
altered
- if RTT is not available then 3d clouds are not drawn at all
- impostors lighting is now recomputed when the sun changes position
- distant objects are no more seen in front of clouds
- blending of distant clouds is a bit better now
- litle optimization of code (uses a less cpu time)
- use layer wind speed and direction (no more hardcoded wind)
- fov is no more hardcoded
Changes
=======
- clouds (cu only) are dissipating/reforming (experimental)
- compute a turbulence factor that depends on surrounding clouds and type of
clouds (experimental)
- clouds shapes are defined in cloudlayers.xml
- type of clouds present in a layer is also defined in cloudlayers.xml
- cloud layers are generated from metar and other misc. data (in progress)
- added a rain effect around the viewer (enabled in the rendering dialog and
when the metar property says so)
- added a lightning effect (enabled in the rendering dialog) : cb clouds spawn
new lightnings
- added a dialog to select from different weather source : metar/property,
a 'fair weather' environment and a 'thunderstorm' environment.
I was going through the Ai scenarios and see that some of them are not
necessary.
Also, I've added some documentation to the other scenarios. And I moved the
thunderstorm over San Francisco, so you don't have to take off to see it.
The files are attached.
they want the feature or not, based on what they see. Having to click on
"Apply" every time is cumbersome.
- show the slider values
- remove the now obsolete buttons (KISS)
- added "my" title bar, albeit without close button (I was *very* tempted :-)
- new and updated sources for the new volumetric clouds
- 2 new textures for the clouds
- an update to the render dialog to enable/disable and change a few parameters
for the new clouds
Implement simple help system with global and aircraft specific dialogs:
The gui.nas changes have been discussed with Andy. All ac have a help dialog,
but some are empty. (This wouldn't have been necessary, as the system falls
back to the "Common Aircraft Keys" if an aircraft has no help defined, but an
empty dialog is less confusing and encourages to be filled with interesting
information. :-) I scanned all aircraft files for interesting performance
data and added some to the dialogs (stall speed, etc.) The Concorde and the
p51d have (over?)complete dialogs and can serve as examples. The format is
documented in $FG_ROOT/Nasa/gui.nas.
There is also a couple of other, minor fixes.
The following files have ugly MSDOS line endings:
$FG_ROOT/Aircraft/Hunter/hunter{-2tanks,}-set.xml
$FG_ROOT/Aircraft/A380/A380-set.xml
The Concorde-jsbsim.nas file is a useless copy of the real */nas file, which is
in Nasal/. I'was debugging the Concorde and wondered why changes to this file
had no effect ...
(Fixed Concorde in the help-ac.diff patch: don't use "interpol" keyword as
variable.)
