Well, that will in effect turn off everything using the rendertexture code.
I would vote against that ...

Would it be possible not to initialize the rendetexture code if we don't need 
it, e.g. we have not 3d clouds enabled?
Does somebody have objections?

Very nice 3d clouds indeed ! ( fliing around with the ufo is great :)

but, what has happened to the thermal scenario ?

i tried to fly the sgs233, but this leads to :

[Flightgear-devel] unhandled write

2005-11-15 Thread Wendell Turner

Monday's CVS seemed to work fine.  If the command line included
the argument
 --telnet=8898
fgfs ran ok.

However, with this evening's CVS, with that argument, I
get this:
 WARNING: Network: 17: unhandled write
 Bus error
and fgfs halts.

I don't mean to whine about bugs; I realize that everyone
is working hard on getting v0.9.9 out.  I'll try to look
into this, but others may know more about this than myself.

For some reasons, the logic between line 1832 and 1858 in RenderTexture.cpp is 
causing X to throw GLXUnsupportedPrivateRequest for those who are using r200 
driver.  The problem would be gone if one were to make an early exist by

BS! I've no idea where I looked that up. 35 is EDEADLK (deadlock:
"Resource deadlock would occur"). Reason according to "man pthread_join":

  EDEADLK
 The th argument refers to the calling thread.

I do know that the carrier is not really compatible with pausing the sim (at 
least that was the case a month or two ago; I've been working on other stuff 
recently and not testing the carrier much.

I'd be suspicious that you haven't got a clean cvs tree there and still have 
some old stuff hanging around.  You did remember to "make install" didn't 
you?  I know I've forgotten at times in the past...

Re: [Flightgear-devel] The right way to use the property manager?

2005-11-15 Thread Harald JOHNSEN

Kitts wrote:


Hi all,

I have been doing some coding and using the property manager in flightgear 
but i want to know what is the right way to do it.


I use the method "fgGetNode("/path/to/property", true)" to get an existing 
property or create one if not there. There are a few things i want to know 
that i list below:


1) A node that is used in the flight system also results in the method 
"isTied" failing and the It does allow me to tie this already existing 
property to a variable?!? Is this the expected behavior? Isn't the property 
supposed to be tied to a variable somewhere already?
 

No, properties are not stored by default in the program 'variables', 
that's why they are not tied.
In practice however there is a lot of properties wich have some get/set 
code associated with

them, and very few wich are directly tied to a variable.

2) When a property did not previously exist, is it necessary to create a 
variable and tie the node to that variable? I find the system to be working 
either ways. If i do not tie it, the property is displayed as "double" in 
the property browser else it displays the data type that it has been tied 
to.
 

If it's tied to a variable then the property will allways be of the 
right type. Else it will has the type
you gave it when you created it / accessed it the first time. Even if 
you write something in another
type it will keep it's creation type. The props functions are doing all 
the casting for you.


3) When the property has been explicitly tied, no matter what the value is 
initialized to using the "setDoubleValue" method the property browser shows 
the value as zero. This display of zero does not happen when the property 
is not tied explicitly.
 

Perhaps are you overwriting the value in your code (and why would you 
use setdoublevalue in your
own code when you can directly write in the container variable ?). Look 
at the AIBase class,
they use tied properties and you can check the values in the property 
browser. Btw, for properties tied
or having a setter function, the property browser *won't* update the 
value displayed when the

property change. You must close/open the property browser to see the change.

4) I would also like to add a change listener to the class that i have 
written so that the class is informed as and when a variable being watched 
has changed value. I believe the way to do this is to use the 
"SGPropertyChangeListener" class as a base class and implement the 
"valueChanged" method to do the job. Is this correct?
 

I think, never done it myself. Note that if you own the property you can 
also use a set function
to update its value, and then you allways know when the property has 
changed.


So now, back to my question. What is the right way to use the property 
manager? Which are the right methods that are to be used and in what 
sequence?


 

If you own the property and you manage it I think the usual way is to 
use the C++ style, ie you use a get and a set function to access the 
member, so you can use fgTie(propertyname, this, get_function, 
set_function).

If it's not your property then you use fgGetXXX.

Harald.

[Flightgear-devel] Conflicting clouds

2005-11-15 Thread Martin Spott
Hello,
I see a strange effect that is related to 3D-clouds.
I am starting FG from EGPH with 'simple' clouds by setting
"--enable-clouds" on the commandline. Current METAR is:

  EGPH 151720Z 25006KT  FEW030 05/01 Q1008

and FG translates this into a "few" cloud layer at 3135 ft having a
thickness of 65 ft. That's o.k. for me as the clouds look nice  :-)
Now I enable 3D-clouds at runtime via the menu and   all clouds
disappear, even the "few" layer.

Does anyone have an explanation for this ? These days I experienced a
similar effect when _two_ cloud layers were present. After enabling
3D-clouns the upper of the two seemed to disappeare, the lower still
was there. Unfortunately I can't tell if there actually were 3D-clouds.

Regards,
Martin.

[Flightgear-devel] impending v0.9.9 release

2005-11-15 Thread Curtis L. Olson

Hi all,

I would really like to get v0.9.9 out the door this week ... maybe 
committing to the final source code version on thursday or friday.  
However, I would like to give everyone the opportunity to mention any 
show stopping bugs that we should be concerned about.  It's ok to report 
bugs, but at this point we really need people reporting *fixes*.  The 
magic source code gods have this week off so we are going to have to fix 
all the bugs ourselves. :-)


At this time I'm not referring to missing features, and I'm probably not 
interested in discussing long standing limitations.  Right now we need 
to find any recently introduced, or big show stopping problems and fix 
them in the next day or two.


I really really want to get v0.9.9 done this week.  If we wait until 
next week we run into the Thanksgiving holiday here in the USA.  And if 
we put things off another week after that, who knows what my schedule 
will be like.  I really want to get this out this week!  And barring 
something really awful, I plan to do the official v0.9.9 release 
thursday or friday.  So that will be the cutoff and we will take 
whatever we have in cvs as of then.


Thanks,

Curt.

I actually did nothing but started with the following

--aircraft=hunter --carrier=Nimitz

The situation was like what I just decribed from the

I have tried Shift + b and it was the same. It's
especially weired that when I pressed P to pause the
simulation, Hunter started to move forward according
to the carrier. I am really confused. :-/

Just checking the obvious - you have engaged the parking brake, haven't you? 
(Shift - b)

Likewise, on land, if the 747 is sitting on a sloping runway without the 
brakes on, it will naturally roll downhill.

[Flightgear-devel] Problems in the latest CVS version

2005-11-15 Thread Dai Qiang
Hi guys,

I got some problems when compiling the latest CVS
version of FG. I don't know if other people have
similar problems.

I am using the latest CVS version of SimGear,
FlightGear data and source. After I enabled the Nimitz
demo, I found the Hunter plane moved backward slowly
when it's landed on the Nimitz, because Nimitz was
moving forward, and Hunter remained at its original
position. I didnot have that problem with Cessna and
B1ooD in the default airport. But the situation was
similar to Hunter on Nimitz when I started with a 747
in the default airport.

Vivian told me it's an old bug that has been fixed
long time ago, but I am actually using the latest
version of everything. 

Any kinds of help would be appreciated, thanks in
advance.

 - Qiang

Yes, but not before 0.9.9 has been released.

Hi all,


   It seems the Data/ directory is missing in the pre3 package, which 
basically contains only Data/AI/ at the moment, and hence explains a

few people not able to use the nimitz carrier (Data/AI/nimitz_demo.xml),
and fgfs will simply terminate with a very vague message saying
"terminate called after throwing an instance of 'sg_io_exception'"
(reported by azuron on IRC).

Good stuff - as far as I can think, you ought to have a fairly straightforward 
time building either now that you have the glut problem sorted out.

I don't frequent any other IRC channels, but #flightgear is generally quite a 
pleasant place, and great for getting quick answers to wee questions that you 
might not want to bother a mailing list with...
