block (this required to move most of init() into postinit())
- undo the "which" pseudo-namespace workaround, and do it proper:
- let all nasal code in a joystick config file be executed in its own
namespace. This allows to define functions in the init block that
can be used throughout the driver file, and to write state variables
in one binding, while reading them in other bindings, all without
having to make sure that the values aren't lost in between, or collide
with another joystick driver's code.
For this the input subsystem creates a namespace for each joystick:
"__js0" for joystick 0, etc. The two leading underscores are there to
avoid collisions with user defined modules (similar to internal compiler
variables). The namespace shouldn't be used explicitly, at least not in
releases, and not from outside code, except for testing purposes, for
which it can be useful. (If using the Cyborg joystick as js[0], you
can read the modifier level as "__js0.modifier" from any nasal context.)
- make it public
- enable handleCommand() to execute a binding (or other nasal code defined
in a property system subtree) in a particular namespace (-> "module" child)
These changes represent some attempts to bandaid and patch a hopelessly
flawed system to impliment basic battery charging/discharging as well as
provide the ability to model ammeter gauges and draw current from multiple
sources (like load balancing multiple alternators in a multi-engine aircraft.)
The system design forces all these things to be horrible hacks or depend
on extremely subtle system side effects and call ordering so they may or9
may not work to one degree or another.
As mentioned in the mailing list, my recommendation is to move away from
using this system and instead build a procedural electrical system using
nasal. Sometime in the future we hopefully can impliment a better conceived
data driven electrical system model.
to the joystick index (x in /input/joysticks/js[x]) both when initializing
nasal init blocks & whenever updating the joystick. That's the only way to
make these nasal contexts aware of the joytick for which they were called.
And that's useful if a js maintains common variables, such as modifiers or
state variables, that should be shared between the namespace-less bindings
and initialization code. And, yes, it's over-engineered ... :-)
its own data, and can distinguish itself from other instances of the
same js driver. This property is removed after script execution.
Example:
self = props.globals.getNode(getprop("/input/joysticks/this"));
(no need to list the paths explicitly in $FG_ROOT/joysticks.xml any more)
- move identified js nodes to /input/joysticks/js[0-9], but
- don't overwrite already set joystick data there
- remove all nodes when they aren't used any more
- add "id" node, which contains the js id that lead to the selection
of a "named js" config
- add "source" node containing the path of the used js config file
- execute all nasal script groups at initialization time
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.
this is basically the past patch I sent to the list and which should now
really (...!?!?) fix the no ground below aircraft problem.
Reasons:
I understood my remaining thinko I introduced with the prevous patch, and the
same thinko I made in my test cases.
The feedback from the list told me that it should help.
2.
I made YASim query the the ground cache at the wrong place. This one fixed
this, one can now land the bo105 on top of the oracle buildings :)
3.
Is a followup of the scenery center update code: Register the scenery center
transform at the time it is put into the scene graph not at creation time.
4.
I held that part back from the past hitlist patch, because I hoped that it
will be sufficient (and the last one was in fact the biggest part) without.
As some test cases from Melchior showed me, it is not. We have additionally
to the wrong computed transform from the prevous patch some roundoff
problems. This patch adds some small tolerance to for the point in triangle
test.
... may be one even needs to increase the eps value further if starting at
some tile boundaries still fails.
5.
That is a big chunk.
Tested now for two days while hunting the second patch :) .
That is a partial rewrite of the groundcache to use its own datastructures for
that flat scenegraph in the cache. The basic advantage is, what Erik
suggested, to precompute some often used values of these triangles. Also
allmost all computations are now in double precision which should decrease
(hopefully fix), together with a similar tolerance for some point in triangle
tests, the problems with 'no ground below aircraft'.
I am playing with octrees for the groundcache, that will finally solve the
performance problem when high triangular count models end up in the
groundcache. This patch is also some prework for those octrees ...
It happens regularly during normal operation (ufo!) and only informs about
unfortunate, but known and deliberate behavior. The user can't do anything
about it, anyway. And finally: flooding the console with this message does
only *add* to fgfs' sluggish performance and makes every other message
go unnoticed.
Changes
=======
- correct the transparency probleme when old 3d clouds were enabled
(rendering context with an alpha channel)
- changed rain cone orientation, it can now be viewed from helicopter or chase
view (still not tower view)
- clouds are a bit more yellow/red at dawn/dusk
- weather data is now correctly propagated to the interpolator, this correct
visibility, wind, etc
- the 'metar' weather scenario now immedialty reuse the real metar data
- real metar no more overwrite custom weather scenario
1) The AIStorm sets the properties:
/environment/turbulence/magnitude-norm
/environment/turbulence/rate-hz
The actual turbulence effects are handled by the FDM.
If the effects are deemed unrealistic, then that will
have to be fixed in the FDM(s).
2) The zone of turbulence is cylindrical, and is centered
at the AIStorm's lat/lon. The diameter is set with
<diameter-ft>, the top with <height-msl>, the bottom is
assumed to be at <altitude> minus 1000 feet.
3) Note that the zone of turbulence may not match well with
the visual model of the storm. In this case I had to
x-offset the storm model by 4700 meters to match the zone
of turbulence. (i.e. the storm model is 4700m off center).
4) While I was in there I also increased the speed of the
lightning flashes to look more realistic.
