- rename <interval> to <wait>
- add <step-time> and <exit-time> on the <tutorial> level for default
step iteration and exit time
- let <init>, <step>, <error>, <end>, <abort> share handler for
<marker>, <set>, <view>, <nasal>
$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
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.
- 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> ;-)
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
- add <marker> support (blinking magenta circle to point to switches etc.)
- use "real" conditions instead of tutorial-only ones
- list of <error> with <message> and <condition> children, instead
of one <error> group with <check> items (necessary because of <condition>)
- only one <exit> (use <condition><and>... to define a set
- rename properties <prop><val><msg> to <property><value><message>
(consistency with other systems)
- <end><message>/<voice> instead of <endtext> and <endtext-voice> etc.
- add <nasal> support everywhere, with separate namespace and predefined
tutorial functions in it (currently only say(), next(), previous())
- make <timeofday> property actually work
TODO:
- more cleanup/re-organization
- add optional <view> group, to direct user view to switches (for startup
tutorials etc.)
2-space indentation changed to tabs (with Stuarts permission), and braces
to K&R style (rationale on request :-)
