Rewrite the position-init code for carrier starts, to precisely wait
on the carrier model being loaded, before proceeding with FDM init.
This allows the FDM to see the correct carrier model in the ground
cache, and hence avoids starting in the water.
To implement this, the CheckSceneryVisitor is used to force the carrier
model to be loaded while the splash-screen is visible.
- remove some global headers from AI headers, to avoid pollution
- change how ATC owns the ‘player’ FGAIAircraft so reset works
- ensure AIAircraft controllers are cleared on unbind for reset
- Introduce a new LOD: ai-interior
- Load a <model> with <usage>interior</usage> on-demand
- Avoid to load the cockpit of players in MP
- Default LOD is 0.0 - 50.0 meters
MP aircraft are loaded by a separate OSG thread (introduced after FG2.4.0).
The OSG thread also calls the "modelLoaded" callback. However, we mustn't
allow the OSG thread to call FGNasalModelData::modelLoaded directly:
FGNasalModelData isn't thread-safe. There are obvious issues (_callCount++;),
tricky issues like calling the Nasal _parser_ or creating hashes and
modifying the global Nasal namespace. It doesn't use locks to protect
against another thread executing a Nasal context or running garbage
collection. It also executes Nasal code itself (the model's "load" hook),
which we also cannot allow in a separate thread...
This patch returns all Nasal parts of MP-aircraft loading (parsing,
module creation, execution) to the main thread, while keeping the
multi-threaded OSG part (loading of MP-aircraft model files itself).
The same issue exists with scenery models (see other commit).
To summarize with 2 words: It s*cks... ;-)
Add a LOD (range animation) to each AI model if the property
/sim/rendering/static-lod/ai is set to any number greater than
zero. AI models get loaded but only displayed when closer than
the number given in the property (in meters).
If the property is absent or it's value is less or equal 0.0
than no LOD is added to the AI model.
Move the disable-HOT feature from the MP aircraft to the a/c base class,
disable HOT for all AIaircraft, since that's a fix/work-around for
#242: AI aircraft respect the user a/c only when HOT is _disabled_ for them
#221: AI aircraft don't stack at parking positions when HOT is disabled
Also generally disables HOT for ballistic and other models (suggested by vivian),
allowing it for ship/carrier models only.
- this exposed a bizarre issue on Mac where dragging in <AGL/agl.h> in
extensions.hxx was pulling in all of Carbon to the global namespace
- very scary. As a result, I now need to explicitly include CoreFoundation
in fg_init.cxx.
- change SG_USING_STD(x) to using std::x
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
- Airports Directory
Thomas Foerster: Pulls out the FGTaxiNode implementation into gnnode.cxx.
Melchior / Durk: Copy Constructor and assignment operator for FGTaxiRoute
- AIModels Directory
Durk / Melchior / Czaba Halasz: Ensure that all derived classes use AIBase
member 'callsign'. Adapted, moved and deleted getter/setter functions where
necessary
Czaba Halasz: Fix AIBase model path vs. submodel path consistency.
- Traffic Directory and AIModels CreateFlightPlanCruise
DT: Temporary revert parts of the position estimation code.
- re-enable od_gauge ("owner drawn" render-to-texture instruments)
- implement radar in c++ (unlimited number of clouds/ai/mp/... objects,
better performance)
- 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
