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
- 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 :-)
Updated CitationX autopilot....
Autopilot is in flightdirector mode by default...
Until instruments are created , enable autopilot by setting "/autopilot/locks/passive-mode" to false
I came upon the TODO asking for illustrations in the 3D Aircraft Models
HOWTO and thought "that's something I can do now!" :)
Merged into model howto by Ron Jensen.
a cursor, after all, and the term "cursor" is already used for the startup
model. That one should really be called "model", but can't, because this is
already used for the ufo 3D model property ... sigh. :-]
- replace lon/lat adjustment with more predictable nearer/farther/left/right
adjustment (i.e. movements relative to the UFO position)
- add key bindings to move objects
