[Flightgear-devel] Propeller reverse ...
Hi all , and Andy,
I've added propeller reverse to YASim , with Controlmap type
PROPREVERSE ... I've tested it with the piston and turboprop , and seems
to be working well . Just wonder if this could be added if Andy approves .
Of course , it might need improvements , but I thought I'd include the
patch for comments , viewing , etc.
All it does is multiply the thrust by -0.2 when the chosen property,
(/controls/engines/engine/reverser, here), is true. Wasn't sure what
the best factor was , most of the data sheets i've
read show blade reverse angles of about -8 degrees.
Hope it can be included ...
Cheers

[Flightgear-devel] Does CVS terrasync work reliably?
The CVS version of terrasync seems to be relying on rsync to notice that the source directory contains more than one file. That's what triggers it to create the destination directory. Seems to me this will fail if there is only one file in the source directory, since it will instead rename that file to the name of the directory. Am I missing something? I've changed my command lines slightly to compensate. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
Re: [Flightgear-devel] New nasal drop, new syntax
Alex Perry wrote Negative 8-). When I recompiled SG and FG after pulling the update in, FGFS started working. Either there was something else that got fixed by this extra recompile iteration, or there is some architecture specific bug you happened to provide a fix for. How interesting. Here, I had got as far as identifying that before about 12 Aug there were no staggers, and afterwards the staggers were such that FG was unusable. Profiling indicated that hash.c was involved, and that meant that nasal was the likely cause. But, try as I would, I could not pin down any individual file. The new Nasal has pretty much solved that problem. Occasional staggers remain, but that is probably to do with threading, and reloading object/scenery etc. Profiling shows that hash.c is no longer the tall pole in the tent, and there are no other particular problems. So while we know how, we don't know why. Was there too much Nasal, or a dodgy file, or was the build defective in the first place, and the rebuild solved that problem? I've spent too long on this problem to try to go back and recreate it; I'm just very pleased that it has gone away. Well done Andy and Melchior Vivian - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

* Heiko Schulz -- Saturday 27 September 2008: Can some explain why it loads the wrong file? That's an intentional bug, a.k.a. (mis)feature. You can also call it poor design. It was introduced after a discussion in this thread (where my objection was overruled): http://www.mail-archive.com/flightgear-devel%40lists.sourceforge.net/msg12849.html And here's another thread where someone called Heiko complains about it ... ;-) http://www.mail-archive.com/flightgear-devel%40lists.sourceforge.net/msg15466.html That feature is also why I have to redefine the OSG_FILE_PATH environment variable, so that OSG doesn't use the shiny OSG demo cow.osg instead of our own cow.ac. m. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
