development. The file must be an XML file with Nasal between a
header/footer. It's a good idea to give it a *.nas extension, so
that editors choose the Nasal syntax coloring.

... here goes the Nasal code ...

all code shares a common namespace, so variables defined in one tab can
be used in another during the whole fgfs session
- make code persistent (saved in autosave.xml)
- better error messages (code borrowed from nasal/lib/interactive.nas)
- clear button (replaces close button, which is now on the title bar)
- help button (explains how to add more tab buttons, etc.)
Aligned hotspots...
Moved kfc200.nas to Instruments-3d where it belongs...
Redoing the kfc200 flightdirector with newer functions (setlisteners) ...still in progress
Updated radios to change standby frequencies instead of selected frequencies....
$FG_ROOT/gui/dialogs/tutorial.xml. It combines the former selection
and description dialogs, which makes browsing much more pleasant.
No more switching back and forth between the two old dialogs. Also,
the <list> box can handle a bigger number of tutorials than the
<combo> box could.
- remove comments from the top of tutorial.nas. The documentation is
now $FG_ROOT/Docs/README.tutorials
- add a <delay> property that can be used at top level (for the default),
and in <init> and <step> (Time in seconds in which the main loop should
run again.)
- fix initialization bug
wrapper call
mf: I didn't find a trace of that /autopilot/controls-overrides/ property
in the fgfs source code and most of the data package. There are regular
complaints in the IRC channel about numpad keys 9 & 3 not working.
the "voice" part. It's no longer possible to display the three letters {|}
in screen message at the moment, but they aren't overly useful. We may want
to support escaping in the future, if necessary.
us3_mbrola doesn't lack some phonemes, causing interrupted messages
- use us2_mbrola for the pilot (seems to be rather complete, too;
pity that the female voice us1_mbrola sounds so ugly :-)
Negative values show that you are actually moving away. To avoid division
by zero, a small value is always added to speed. So, if you aren't moving
at all, you still get a non-infinity, but huge ETA.
- <set> pair: allow to set <property> from <value> or second <property>
- support <set> pairs in <end>, too. This can be used to restore values.
- add optional <view> to <init>/<step>/<exit>/<end>. This is meant for
cockpit tutorials. See the Lightning's startup tutorial for an example.
- add view manager for saving/restoring and moving/interpolating view
axes & fov to absolute values. This is used for cockpit tutorials in
$FG_ROOT/Nasal/tutorial.nas
- check a step's errors in random order (otherwise a retarded instructor
bitches minutes about the climb angle, and only then notices that the
heading is totally wrong ;-) ... mabye simple scheduling would be better
- document embedded <nasal>
- start of <view> support
entries /sim/tutorial/targets/target[n]/{distance-m,direction-deg} are
provided and kept up-to-date. A direction angle of 0 means that the target
is straight ahead, 90 means it's to the right (3 o'clock) 179 means the
target is right behind, etc.
- everywhere where <message> and/or <audio> is supported, there can be more
of those entries, in which case one is randomly chosen. This is to make
the instructions less monotone:
<message>You are too fast. Fly at 100 knots.</message>
<message>Not so fast. 100 knots are more than enough.</message>
<message>Slower! Idiot!</message> ;-)
- simple geo coordinates class: geo.Coord with methods to set/get single
components, to apply distance/course and the get distance/course to other
coords
- functions that return click and aircraft position as geo.Coord
- function that returns tile_path for given lon/lat
- function that returns normalized angle (0 <= angle < 360)
Help->Nasal-Console opens the adjustment dialog
- reset Nasal namespace for emebedded Nasal for every tutorial
- rename <voice> to <audio> (in the hope that this won't be mixed up
with Festival voice synthesis; should we call it <audio-sample>?)
- rename <instruction> to <message> for consistency reasons, so there
are now <step><message>s, <error><message>s, and <end><message>s
