Problem 2 (Nasal approach) : I'd really like to use Nasal but there is no sane way to play audio files via Nasal. Creating hundreds of properties in the property tree tied to audio files isn't a nice solution. Also FlightGear doesn't support Ogg Vorbis files as far as I know and having a lot of audio feedback from the instructor is vital and certainly makes the whole process a lot more realistic and enjoyable. I'm getting a 10:1 reduction in file size using the Ogg Vorbis format on my instructor recordings. Files that are 0.5MB in WAV format compress down to about 35KB in Ogg Vorbis format and I can't tell the difference in quality. At the moment I'm at a standstill trying to figure out what to do. This external app thing is going to become a problem and I don't want to invest a lot of time into it and then have to recode everything in Nasal later.

If it is easier for you to develop maintain externally, I think you can stop bothering about the less technically minded people. Anything with package dependency tracking capability (like any modern linux distribution) will automatically pull the relevant software in. The more technically minded folks will be able to install the relevant packages for manual compilation, and the rest will wait for a prepared distribution package with the proper dependencies in. (I am unsure though if this might strain the win32 bundling process significantly, though. Surely Frederic knows?) Vassilii --- This SF.net email is sponsored by: Splunk Inc.

[Flightgear-devel] Lessons in FlightGear
Hello, I've read the thread of Paul Surgeon Tying scenario specific code to aircraft and i think it could be good to do something like this : It's hard for me to explain what i'm thinking about with my poor english, so i've made a example and draw a GUI : http://j2rpg.photos.free.fr/scenario/start.png Each lesson is divided into stages (Take Off, Climbing Out, First Corner... etc) and each stage have a flag (White = stage is not finished, Green = successfull, Yellow = Small mistake, Orange = Medium mistake, Red = Retry) Instructions are displayed only for the current stage (in my example, the current stage is First Corner...). An XML file for Lesson 1 could be : ?xml version=1.0? !-- Lesson 1 binding definitions. -- StageList stage n=0 nameTakeOff/name instructionsGo at 60 knots and Take Off/instructions EndOfStageAltimeter=100/EndOfStage !-- Here we have the value to test if it's the end of the stage-- MaxTime45/MaxTime evaluation cap10/cap !--red flag if the cap change more than 10°, Orange from 7° to 10°, yellow from 4° to 7° and green under 4°, for example-- knots60/knots !-- don't know yet how to test an acceleration -- /evaluation /stage stage n=1 nameClimbing Out/name ... /stage stage n=2 nameFirst Corner/name instructionsTake the cap 010/instructions ... /stage ... /StageList I don't know how to do everything but what you think about this idea ???
