aircraft can plug a custom function. This function can access all internal
variables of the ViewManager class. It can set me.{x,y,z}_offset, and also
add offsets to me.{heading,pitch,roll}_offset. Example:
dynamic_view.register_headshake(func {
me.x_offset = rand() * 0.02; # Parkinson effect
});
The advantage of this implementation is that it doesn't break MMB drag
functionality, and that is can be frozen by mouse movements.
or of given frame
- add debug.string(<variable>). This returns the variable dump as
string.
- add var to module function variables to avoid collisions with module names
Remember: dynamic_view.lookat(heading, pitch, roll) moves view
smoothly to this direction, while dynamic_view.lookat() moves it back.
This can be used for quick view changes to the panel etc. It's currently
only used in the bo105 (flaps-up binding).
This isn't only more logical, it's also how SGPropertyNode::getBoolValue()
acts. The fix has potential to break code, but so far I haven't seen any
problems. I added a debug message to my copy and will for a while check
all cases that I run into. To check yourself, just add one line:
getBoolValue : func {
val = me.getValue();
+ if(val == nil) { debug.dump(me) }
if(me.getType() == "STRING" and val == "false") { 0 }
else { val != nil and val != 0 }
}
This will output a debug message to the terminal for each case where
formerly "true" was returned, and now "false" is.
- use Nasal features that were introduced after this code was first written:
* var for local variables (and to make clear when a variable is first used)
* += operator
* listeners to import seldom changing variables and to avoid waiting for
the FDM in a loop
This new code started as empty file where I added my stuff and then copied
parts from the old code, piece by piece. This is why the coding & indentation
style has changed. Functionally the code should basically be equivalent.
can also write
<sim>
<aircraft-data>
<path>/sim/author</path>
<path>/sim/description</path>
<path>/sim/rtatus</path>
</aircraft-data>
</sim>
in a *-set.xml file instead of using Nasal (aircraft.data.add("/sim/author", ...)
- s/timeN/node/ to match the pattern described in the head comment
- make listener on-shot
- make 0 a valid saving interval, and 'nil' or no arg stop the loop
(this is for consistency with settimer() or aircraft.timer() intervals
- smaller fixes, cleanup
Examples:
var tied = foo.getAttribute("TIED");
foo.setAttribute("USERARCHIVE", 1);
Both methods accept attribute strings "READ", "WRITE", "ARCHIVE",
"TRACE_READ", "TRACE_WRITE", and "USERARCHIVE". getAttribute() does
additionally accept "TIED" (although this isn't an SGPropertyNode::Attribute).
Attribute "REMOVED" is not supported.
registered with dynamic_view.register() and is called in the main loop,
replacing the default plane/helicopter function. This has access to
all class functions/members and sets me.heading_offset, me.pitch_offset,
and me.roll_offset, which are then used as new view offsets.
The function can also do other things, such as call the lookat() method
to temporarily set heading and pitch. See the bo105 for an example.
While further minor changes are to be expected, the configuration method
seems to be the way to go.
- dynamic_view.nas: use aircraft.lowpass() class
This makes the dynamic view independent of the frame rate. Currently,
each filter instance reads out dt on its own, which is a bit inefficient.
I'll change that to just one read for all instances later (when Nasal
implemented predictable module loading order. :-)
- fix sliders: revisions 1.43/1.44 had introduced a mandatory <min-lb>;
if that was missing, a slider without handle was generated, and a click
on the slider lead to a crash.
-> check for both <min-lb> and <max-lb> and set default values
0, respectively 100
var min = w.getNode("min-lb", 1).getValue();
var max = w.getNode("max-lb", 1).getValue();
slider.set("min", min != nil ? min : 0);
slider.set("max", max != nil ? max : 100);

tank indices, so that changing drop tanks automatically modifies the
corresponding FDM tank capacity (and load, if it is too high).
Add the new tank stuff to the harrier config, along with a few new
items (e.g. AMRAAMs on the outboard pylons) that aren't in the 3D
model yet, but correspond to actual usage.
An IRC discussion about shavlir's (really nice) harrier model showed
that it had its own version of something like the Fuel & Weight
dialog, developed because the existing subsystem only supported
sliders and not "combo box" style selection for specific external
stores. That seemed sub-optimal, so I spent a few hours extending the
F&W dialog to do this and forward-ported the harrier to use it.
Check the harrier-set.xml file for an example. Basically, the weight
dialog reads a list of options for each weight listed under
/sim/weight[n] and manages a "selected" proprty telling us which one
is in use. The FDM code can then read out the weight-lb property as
before, and the model animations can use the selected option to
predicate drawing the appropriate 3D content. It seems to work pretty
well.
Unfortunately, this is quite jittery on some aircraft, so it uses a slower
lowpass filter. I'd like to fix that, but don't even know what causes it.
Considering /sim/time/delta-realtime-sec didn't help. :-/
entry "View->Toggle Dynamic Cockpit View" entry; state saved to autosave.xml;
there are no configuration parameters yet, but the default values work for
most aircraft; exceptions: ground steering effect of jsbsim aircraft is
jittery; yawing effect on big aircraft is too abrupt. This needs to be
configurable.
Suggestions for improvements are welcome if they are bundled with a
working diff that actually proves the claimed advantages. :-)
<close> block, remove autopilot helper file autopilot.nas and (re)implement
its functionality in autopilot.xml
- make AP dialog "bidirectional" and "live": all input fields are <live>
(i.e. they are updated as the autopilot settings are changed, for example
by panel actions or property browser changes)
- dialog input is only forwarded to the AP; no direct checkbox/radiobutton
handling through widget operation, instead:
- changes to the AP properties operate checkboxes/radiobuttons
This makes the AP dialog always reflect the AP state. If the AP refuses
one setting and sets it back to something else, then the dialog will
immediately react and show the actual setting.
mf:
- some minor modifications to Stuart's version :-)
- select all engines per default. This may seem less realistic (who starts
all engines on the b29 at once?), but it'll prevent oodles of bug reports.
And those who want it realistic shouldn't rely on engine 1 being selected
by default, anyway, but rather actively select every single engine.
Also: this new behavior is in line with the original intentions (see cvs
log to preferences.xml -r1.51)
- always disable tutorial-stop; enable tutorial-start if tutorial available
- don't call the tutorial selector "Wizard 1/2". There is only one tutorial
selector, the next dialog is already part of the tutorial. Also, the dialogs
don't guide you through multi-dialog setup, which is what "wizards" normally
stand for.
- use tutorial name as dialog title
- set button shortcuts (default == return, esc)
- make esc go back to select dialog
- beautify sliders & some other tweaks

gui.nas: replace inefficient FPS display polling loop with listener
callback
- gui.nas: use 4-space indents like the rest of the file; waste slightly less
cycles: checking for the property shouldn't be done in a loop at
all, it only serves as a temporary solution
to pop themselves down while the simulator is paused.
The problem was with the "real time" queue in the event manager,
causing the third argument of Nasal's settimer() (a flag for "sim
time") to be ignored. Inverts the default sense of the argument, as
there are lots of uses of settimer() in the current code, almost none
of which want to use real time.
Note this fix introduces a header file incompatibility in SimGear --
be sure to update.
gear movement. gearToggle() was sending either a 0 (not handled) or a 1.
Change gearToggle() so it sends either -1 and 1 so gearToggle() will work
again.
