Hi All, Based on the discussions started by Paul and Cyprien, I had a go at writing an XML-based tutorial system in Nasal.
It is still fairly rough, but is available as a patch here: http://www.nanjika.co.uk/flightgear/tutorial.tar.gz. The patch consists of: - a simple "take-off" tutorial for the C172p, as an XML file. The XML defines a number of tutorials, each of which consists of - an initialization state - a number of steps, each of which has - text displayed when the step begins - exit criteria to move to the next step - error criteria, displaying warning messages. - a tutorial library (tutorial.nas) that runs the tutorial. - a new Tutorial dialog, accessed from the Help menu, that dynamically works out the tutorials that are available. The most obvious omissions currently are: - The dialog box isn't great. It would be great if a description for each tutorial was displayed when the tutorial was selected. - Currently the end of the tutorial displays a message with the number of errors. This should probably be a dialog. - You cannot set properties outside of the initialization. This is almost trivial to add, and would be great for engine-out tutorials. - No audio instructions, though I think I now know how to add them to Nasal and therefore to the tutorial system. - I'd like to be able to run Nasal scripts defined within the tutorial XML file. Let me know what you think. Paul, Cyprien: Apologies if I've stepped on your toes by putting this together. If either of you would like to take the patch onwards, I'm happy to leave you to it.
