[Flightgear-devel] Segmentation fault using --native option
Hi, I got a segmentation fault using --native=file,in,10,test --fdm=external where the file test is 12MB big Then I tried with a smaller file (1.2MB) and it worked fine. I'm using FG OSG CVS, compiled yesterday and this is the first time I use this option. The test files are created using --native=file,out,10,test here is the result (last lines) of --log-level=debug with the 12MB size file: Running Main Loop === Updating time Current Unix calendar time = 1174401951 warp = 0 Current GMT = 3/20/2007 14:45:51 Current Unix calendar time = 1174401951 warp = 0 Current GMT = 3/20/2007 14:45:51 Current Julian Date = 2.45418e+06 COURSE: GMT = 2/20/107 14:45:51 March 21 noon (GMT) = 1174478400 Time since 3/21/107 GMT = -0.884826 days = 0 hours = 14.7642 lon = 0 lst = 2.76417 COURSE: GMT = 2/20/107 14:45:51 March 21 noon (GMT) = 1174478400 Time since 3/21/107 GMT = -0.884826 days = 0 hours = 14.7642 lon = 122.357 lst = 18.607 Current lon=0.00 Sidereal Time = 2.61449 gst = 194.614 Current LOCAL Sidereal Time = 18.4573 (18.4573) (diff = -0.149675) Elapsed time interval is = 716961, previous remainder is = 1083 -- Frame rate is = 7 Model iterations needed = 86, new remainder = 1378 Finally initializing fdm Start common FDM init ...initializing position...

More tutorial changes to expect ... I'm looking forward in particular to the lookat thingy, that should be a very nice touch... For other aircraft authors (or even those who aren't, but would like to contribute their knowledge of various flight procedures etc), I'd encourage people to have a look at adding more tutorials. The process is really not very difficult (reading the existing examples should be quite sufficient documentation) and as usual help can be had from here or the IRC channel. These tutorials can be a big help to people just starting out with FG, and are so much better than a dry description of processes. I'm also certain that with a little imagination our (amazingly flexible) tutorial system can be abused a bit to add all sorts of other interesting functions and scenarios into FG ;-) Cheers, AJ - Take Surveys.

I'm also certain that with a little imagination our (amazingly flexible) tutorial system can be abused a bit to add all sorts of other interesting functions and scenarios into FG ;-) One scenario I thought might be quite fun to put together would be a helicopter Search and Rescue. This led me to think of new features that would make writing such a tutorial easier. 1) A distance-to function, that would evaluate to true when the user was within a given distance to a point (expressed in lat/long). This would be more useful than the current work-around that forces the tutorial writer to define a box with given long/lat sides. 2) The ability to define objects in the scenery within a tutorial, e.g. adding a downed aircraft/missing walker 3)The ability to trigger select animations on objects. This is possible indirectly by writing to a property, but isn't ideal. Of course, this is all stuff I should be adding myself, but I'm sure Melchior could put together a much more elegant solution before I got as far as recompiling FG with the latest CVS :) -Stuart ___ What kind of emailer are you?

Re: [Flightgear-devel] tutorial news
I just committed some changes. Among other things, one can now also open the tutorial marker adjustment dialog by typing tutorial.dialog() in the Help-Nasal-Console, so people don't have to bother defining key bindings. It's not such an often used feature. * Stuart Buchanan -- Tuesday 20 March 2007: One scenario I thought might be quite fun to put together would be a helicopter Search and Rescue. Yes, I thought of that, too. Missions where the copilot directs one to the car accident etc. (Follow the street ... Ten miles ... Ohh ... that doesn't look good ... :-) 1) A distance-to function, [...] Should be easy. The Nasal code for that is already in ufo.nas. Just need to factor that out in a separate library. 2) The ability to define objects in the scenery within a tutorial, e.g. adding a downed aircraft/missing walker That's already possible. I implemented that for the ufo scenery object editor. And the bo105 placed Memorial Cows at crash locations, but this service wasn't well received ... ;-) Just need to add a small function. 3)The ability to trigger select animations on objects. This is possible indirectly by writing to a property, but isn't ideal. Well, properties are really the only way to communicate with animations, and that's not a bad thing. You can now embed Nasal in tutorials, so there's nothing stopping you from launching an interpolate() etc. before I got as far as recompiling FG with the latest CVS :) There were no changes in C++. You just need to update data/cvs (which works for both branches -- with the sad exception of some traffic stuff, which we should really migrate. There's really no point in having two branches with this being the only difference. m. - Take Surveys. Earn Cash.

* Stuart Buchanan -- Tuesday 20 March 2007: 1) A distance-to function, that would evaluate to true when the user was within a given distance to a point (expressed in lat/long). This would be more useful than the current work-around that forces the tutorial writer to define a box with given long/lat sides. Implemented. One can define one or more targets: targets target longitude-deg-122.37931/longitude-deg latitude-deg37.626/latitude-deg /target target longitude-deg-123.456/longitude-deg latitude-deg34.567/latitude-deg /target /targets ... and the tutorial logic will offer distance and direction of the aircraft to each of them as /sim/tutorial/targets/target[0]/direction-deg /sim/tutorial/targets/target[0]/distance-m /sim/tutorial/targets/target[1]/direction-deg /sim/tutorial/targets/target[1]/distance-m A direction of 0 means that the target is straight ahead, 90 means it's on the right, -90 on the left, -180 or -179. in the back. This can then be used in conditions. Another improvement is, that one can now define more than one message or audio, in which case one is chosen at random. See the cvs log message for an example. :-) m. - Take Surveys. Earn Cash.
