Hi,
Re: http://www.geoffair.net/tmp/tilted-001.png
Again, thanks for the multiple inputs...
1. __tailwind__
(a) John, I wanted to try your metar to see if it looked
related, but like Arnt I can not get the metar string through
the command parser!
Always -
Fatal error: Failed to open file
at 012345Z
(received from SimGear XML Parser)
What are we doing wrong?
I tried, like you and Arnt put -
--metar="XXXX 012345Z etc"
then
"--metar=XXXX 012345Z etc"
even
'--metar=XXXX 012345Z etc'
--metar='XXXX 012345Z etc'
Always the same error message and fgfs aborts...
(b) But also, I think in most of the trials I had disabled
real weather, or at least not enabled it, so do not
think my case is related to 'wind', but maybe...
2. LFPZ (Grass)
On all 4 runways, all looked ok, although sometimes
there was some unusual a/c 'rocking', after the splash
cleared, usually first down, then up, which 'felt' like
what happens at YGIL, but it seemed to stay on 3 feet ;=))
But that was in an old XP machine, where I do not
see a frame rate much above about 4 or 5, which makes
it virtually unplayable, so am presently redoing a
full git update, and SG/FG rebuild in Ubuntu, to
try there...
>From what Henri said, it certainly seems possible
that nasal is dickering with the "gear Z position
(gear/unit/z-position) ...", or something, so more
to explore here...
I can see in c172p/Nasal/action_sim.nas that it,
in the update_actions function, gets lots of gear
related nodes like -
var dhN_ft = props.globals.getNode("gear/gear[0]/compression-ft", 1);
var dhR_ft = props.globals.getNode("gear/gear[2]/compression-ft", 1);
var dhL_ft = props.globals.getNode("gear/gear[1]/compression-ft", 1);
var propGear0 = props.globals.getNode("gear/gear[0]", 1);
var propGear1 = props.globals.getNode("gear/gear[1]", 1);
var propGear2 = props.globals.getNode("gear/gear[2]", 1);
var nose_link_rot = propGear0.getNode("compression-rotation-deg", 1);
var left_main_rot = propGear1.getNode("compression-rotation-deg", 1);
var right_main_rot = propGear2.getNode("compression-rotation-deg", 1);
and later sets the latter 3 to calculated values...
At the end sets itself up to repeat on each frame -
settimer(update_actions, 0);
And ties itself into -
setlistener("sim/signals/fdm-initialized", init_actions);
and
setlistener("sim/signals/reset", init_actions);
Hmmmm... can not yet see where the r/w 'surface' is in this,
but some things to try here, to at least rule out
this particular nasal, like comment out 1 or all of -
nose_link_rot.setDoubleValue(theta);
right_main_rot.setDoubleValue(right_alpha_deg);
left_main_rot.setDoubleValue(left_alpha_deg);
But out of time today, but will be back tomorrow, after eating
and sleeping on it... I hope... ;=))
Thanks for all the input, and any other ideas welcome...
I look forward to a quiet life at YGIL ;=)) Usually do
not have many visitors, except the kangas...
Regards,
Geoff.
