This is a work-around, probably indicates some glitch in the traffic
module flight-plans. Avoid a crash, also refine the exception logic
so individual AI objects can fail.
If you want a scenario in a particular session of the sim, ask for
it on the command line / config files, or enable in the GUI.
Note if you had previously 'sticky' scenarios in your autosave.xml, you
will still get them until you clean your autosave, or disable them in
the GUI.
AIManager had unfortunate code to pass some state to the traffic-manager; this is no longer required since traffic schedules hold onto their AI-Aircraft directly as needed.
Also adapt MP and traffic module to enable the AI module when required.
This makes /sim/ai/enabled an internal property: it can default to false
(in future), and can be enabled as soon as any user-level feature (traffic,
MP, local weather, ...) requires it.
Replace SG_GENERAL by more specific log classes in many places.
Allow "," to separate logging classes (using "|" is odd on the
command-line).
Also add new option to make logging more useful for developers.
You can use:
--log-level=debug --log-class=environment
to only get environment debug messages, or
--log-level=debug --log-class=sound,ai
to only get debug messages related to the sound or AI subsystem.
--ai-scenario=... can only add/enable another scenario.
Introduce --disable-ai-scenarios option to disable all scenarios (can be
used by external launchers, GUIs etc)
Also provide error instead of debug message when a scenario cannot be loaded.
From Till:
i started the project at the end of february with a simple idea: move all
3d-model loading to the DatabasePager-thread. my first attempts looked
promising, though they were a little too optimistic (or naive?). the patch
has evolved a lot since.
currently it does the following things:
1. revive SGModelLib, move functions for xml-model-loading there
2. replace all calls to sgLoad3dModel with calls to either
SGModelLib::loadModel() or SGModelLib::loadPagedModel()
almost all models will be loaded by the DatabasePager. the few exceptions are:
your own plane, shared models in scenery, random objects, AIBallistic models.
3. simplify mode-loading functions (avoid passing around fg_root)
4. avoid supurious MatrixTransform nodes in loaded models
5. fix some memory leaks
- 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.
