show "secret" values, that is: values of nodes with children. These
can be used like all normal (leaf) properties, but their values were
until now only shown in writeProperties() dumps. Also show the
number of attached listeners. Example: foo = 'bar' (string, AU, L3).
dialog.cxx: add warning message for broken <format>s; cosmetics
- props is easy to mix up with the --prop option (for setting properties)
- the name is unspecific and inconsistent: other option names describe
the protocol -- the way to get the properties. How is, for example,
--httpd less about prop(ertie)s?
- two identical options easily confuse people, as can be seen in The
FlightGear Manual, where --telnet and --props were described differently
/sim/view[*] that it finds. It's not only unnecessary that view definitions
have subsequent indices, but aircraft are now *requested* to use indices
100++. /sim/view[0] .. /sim/view[99] are reserved for the system. (Not
that we'd ever need that many, This is just a convention, it's nowhere
hard-coded.)
- replace the string operations for property paths by method calls & other
improvements
because nasal's f_interpolate() may be called in Nasal at times when the
GENERAL subsystem group is being deconstructed; access it by addressing
the group directly, as using globals->get_subsystem() does then not
work any more then; yeah, it's all for a rare border case ... :-)
NasalSys.cxx more robust instead. The reason for the crash was that during
fgfs shutdown destroyed subsystems (GENERAL group) still need Nasal access
(for AI Model destruction listeners), but at that point globals->get_subsystem()
can't even deliver the "nasal" subsystem (INIT group). One way to solve that
problem would have been to replace globals->get_subsystem("nasal") by
globals->get_subsystem_mgr()->get_group(SGSubsystemMgr::INIT)->get_subsystem("nasal"),
but Andy decided to store a pointer to the active "nasal" subsysten in
NasalSys.cxx instead, as the "nasal" subsystem needs to be accessed in
every single Nasal extension function, and multiple "nasal" subsystems are
out of the question, anyway.
we need to explicitly destroy that here, too, so that it has guaranteed
access to the Nasal subsystem. Otherwise we get a segfault on exit. When
the next subsystem needs this special treatement (radar?), we should
introduce a new subsystem group (in addition to INIT and GENERAL)
"FATAL: PUI: No Live Interface! Forgot to call puInit ?"
We shouldn't use the splash progress message before guiInit().
Leave the "idle_state" step for now, to keep the similarity
with fg/plib as big as possible. This can be dropped later.
one file per type in a simple binary conglomeration of packets with no headers
or checksumming (this format is intended for local storage only, not to be
transmitted on the fly over a noisy communication pipe.)
Patch to enable atc chatter (and any other arbitrary "message" audio file)
to be played at any specified volume. (Previously these messages were always
played at a hardcoded volume of 1.0)
- loop up file name in the cache at startup. If it's found, check if the
file exists and use it, otherwise scan $FG_ROOT/Aircraft/ as usual,
and create a new cache while doing that. Rebuild cache on FG_ROOT change.
getAttribute("archive") returns 1 if the attribute is set, and 0 otherwise.
Allow to query and to set all properties by not specifying an attribute
string: getAttribute() returns all attributes bit coded in an integer,
and setAttribute(attr) sets all attributes. No assumptions may be made
about the meaning of the bits -- they can be changed in future fgfs releases.
The only valid use is to compare or set attribute numbers obtained in the
same fgfs run. This is meant for allowing full copies of property branches.
Also add getAttribute query strings "children" for the number of children,
and "alias".
- fix breakage due to former commit (AIManager.cxx, r1.72)
- make AI properties available in AIBase
- add <valid> property for animations/nasal scripts
- support more MP and AI targets
- add target select and altitude display
their XML wrapper/animation file. They can access their /ai/models node
via cmdarg() function. Example:
<nasal>
<load>
print("Hi, I'm the Nimitz. My data are under ",
cmdarg().getPath());
</load>
<unload>
...
</unload>
</nasal>
Note, however, that the <unload> block is only called on exit at the moment,
not when the tile is unloaded.
