Make the policy of using models in FGData/AI more flexible, with the
option to prefer normal data sources. Keep the existing behaviour for
everything except multiplayer aircraft, where we now prefer the data
model (presumably, an installed aircraft) over the AI one.
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
Here is a patch for two bugs in the AI/multiplayer part:
1. Cannot find model file *.ac error message (was only a false message,
anything worked correctly, the model was loaded from the correct path
afterwards).
2. Often many multiplayer aircrafts are missing in the property-tree.
(but I need them for aerotowing). There is still another bug: The
property in some circumstances seems not to be cleaned up after logout
of a multiplayer. I have added a workaround for this, but I don't now,
if it 100% works (should have no side effects, just aerotow would not
work sometimes). For testing I need more traffic on the mp-server.
This patch removes some useless indirection when creating AIModels. It
obsolets AIScenario*.
AIEntities are just an intermediate copy of an other intermediate copy of an
xml file on the way from the ai scenario configuration file to the AIModels.
As such the AImodels can now be created directly from the property tree read
from the scenario file.
This reduces the amount of work needed to add an other AIModel and reduces the
amount of copy operations done during initialization.
It also moves internal knowledge of special AI models into these special AI
models class instead of spreading that into the whole AIModel subdirectory
which in turn enables to use carrier internal data structures for carrier
internal data ...
Also some unused variables are removed from the AIModel classes.
I believe that there are still more of them, but that is what I stumbled
accross ...
Tested, like the other splitouts these days in a seperate tree and using the
autopilot for some time, and in this case with a carrier start ...
I added an AIStatic object to my OV-10 sim for use in putting city signs,
vehicles, or anything else that will be static, but that I don't want to put
in the scenery files. It's inexpensive. Before, I was making such things
from AIShip.
I also added the ability to set flight plans to repeat, so that when an
airplane reaches the end it just starts over at the beginning. This is
useful for my OV-10 sim. I have C-141 and KC-135 traffic flying approaches
to Ramstein, and I only have to define two AI objects to do this.
Also, I found an inefficiency in AIBase, where every AI object was calculating
Mach number at every dt. Now only AIBallistic objects do this.
