[Flightgear-devel] Nasal in scenery object XML files
FYI: I've now added Nasal support for scenery objects to my copy of
sg fg. This can be used for 'intelligent' objects -- special lighting
features, specific lighthouse signals, things that couldn't be done
with animations alone. The code is run as soon as the tile loader
decided to load the model. It can use listeners and timers and so
run as long as it wishes. If the object is removed from memory,
then a variable is changed in the object's namespace, so that the
code can stop itself. An optional destructor part can be used for
further cleanup (remove listeners etc.)
The required changes for sg fg are minimal, but because of the
nearing release I better send the patches for review after the
release. See below for an example.

Re: [Flightgear-devel] Nasal in scenery object XML files
FYI: I've now added Nasal support for scenery objects to my copy of sg fg. This can be used for 'intelligent' objects -- special lighting features, specific lighthouse signals, things that couldn't be done with animations alone. That is great! Thank you Melchior :-) That will open new horizons to people like me who like adding nice widgets to the scenery. Serious air flight 'addicted' ones will be pleased with more realistic environment too, of course :-) I was trying to get realistic lighthouse signals with the former animation system but that has a few limitations which cannot be overcome with any amount of fantasy. I hope Nasal scripting will help more. The code is run as soon as the tile loader decided to load the model. It can use listeners and timers and so run as long as it wishes. If the object is removed from memory, then a variable is changed in the object's namespace, so that the code can stop itself. An optional destructor part can be used for further cleanup (remove listeners etc.) Is there any chance we can get a nasal-modified binary for Win platform to play with as soon as something works in an acceptable stable way? I'd appreciate that a lot. cheers, Roberto -- Feel free mit GMX FreeMail!

Rather than set this from C++ code, why not use: An optional destructor part can be used for further cleanup (remove listeners etc.) Which can do it all from Nasal with just a single line. And defining it as the second script tag seems clumsy to me; how about calling it on-unload or destroy or something similar?

Re: [Flightgear-devel] Nasal in scenery object XML files
Is there any chance we can get a nasal-modified binary for Win platform toplay with as soon as something works in an acceptable stable way? I'd appreciate that a lot.If the code is in CVS (and to be turned on manually) or in a reasonable clean patch, I can supply you with a windows build. Just ask with a private mail.
