2d03062b38 First stab at a simple script that inputs a list of lon/lat coordinates via
stdin, and outputs the coordinates with FG ground elevation.  This requires
a running copy of FlightGear with --fdm=null and the telnet server enabled.
Of course you need to have scenery installed for all areas you are querying.
This is not fast and the scenery load wait time may need to be tuned for
individual systems.

d712d18acb David Culp:
Here are some things I've added to the submodel code.

First, I added a first_time value that is true when the trigger is pressed and
false when the trigger is released.  The true value is also made false after
the first pass through release().  Release() then uses this to force the
first dt (per salvo) to be zero.  I was hoping this would make the submodel
appear closer to the airplane, but I don't notice a difference with the
tracers.  In a prior test I found that the first dt is about 2.5 times larger
than subsequent ones.  Maybe this will be effective with slower submodels,
like smoke, contrails, etc.

Secondly, I updated the IC.elevation and IC.azimuth calcs to correctly add in
the yaw and pitch offsets, corrected for bank angle.  Actually this is still
an estimation.  A proper calculation will sum the submodels vector with the
airplane's vector.  Until that's done only models which are fired forward
will have proper IC.

fed4a2c25a Vivian Meazza:
I've added another parameter to the submodel - wind.

It's activated by the entry <wind>true</wind> in the ../submodel.xml file.
If true, the submodel is affected by the local wind, otherwise not. The
parameter defaults to false. This is useful for exhausts and smoke, and
possibly all objects.

1853012d90 Vivian Meazza:
Attached are the modified files to add buoyancy as a parameter for a
ballistic object. It may be set by adding

<buoyancy>x</buoyancy> to the submodel .xml file, where x is the appropriate
value (ft per sec2):

	32   neutral buoyancy - contrails
	>32  positive buoyancy - exhaust plumes
	(0   non-op - default value)

If <buoyancy>x</buoyancy> is not used, then there is no effect on the
current ballistic model

fdab44652e David Culp: This is n idea from Vivian, it allows setting the count to a negative number which will give unlimited submodels (as long as the trigger is true). This is useful for contrails. 2004-08-30 09:15:04 +00:00

cfc05f5f0d David Culp:
Silly me.  I was starting the timer at zero, so the first tracer didn't fly
until 0.25 seconds after pulling the trigger.  Now the timer starts at the
same value as "delay", so the first round comes out immediately.

Also, I've added an optional configuration attribute that allows you to change
the ballistics of the submodel.  This allows parachutes, or anything else
that has ballistics different from a bullet.  The attribute is called "eda",
which is the equivalent drag area.  Default value is 0.007, which gives the
same ballistics as the current tracers.  Increasing this value gives more
drag.  A value of 2.0 looks good for a parachute.


math stuff
########################################################################
The deceleration of the ballictic object is now given by:

[ (rho) (Cd) ] / [ (1/2) (m) ] * A * (V * V)

where rho is sea-level air density, and Cd and m are fixed, bullet-like
values. So the calculation is:

0.0116918 * A * (V * V)

The value "A" is what I'm calling the "eda" (equivalent drag area).
########################################################################


A parachute model will have to be built so that the parachutist's feet
are in the forward x-direction.
Here is the submodel.xml config I use for "parachutes":

  <submodel>
    <name>flares</name>
    <model>Models/Geometry/flare.ac</model>
    <trigger>systems/submodels/submodel[0]/trigger</trigger>
    <speed>0.0</speed>
    <repeat>true</repeat>
    <delay>0.85</delay>
    <count>4</count>
    <x-offset>0.0</x-offset>
    <y-offset>0.0</y-offset>
    <z-offset>-4.0</z-offset>
    <yaw-offset>0.0</yaw-offset>
    <pitch-offset>0.0</pitch-offset>
    <eda>2.0</eda>
  </submodel>

065d4d8da1 David Culp, Vivian Meazza:
Last night I sent these new files to Vivian to fix a problem he found.  Since
we can have more than one submodel we need more than one "count" property.
The new code creates a property systems/submodels/submodel[n]/count for each
submodel.  Vivian is using this count property for his sound.

c4aa3fa661 David Culp:
Here is an update for the submodel system.  This will allow submodels to be
defined for any aircraft, and there are no default submodels.  To use this
submodel system you need to set up a binding (slight change in property name
from last one, but you can use any property name you like, as long as it
matches the name in the submodels.xml file, see below):

 <button n="0">
  <desc>Trigger</desc>
  <binding>
   <command>property-assign</command>
   <property>/systems/submodels/trigger</property>
   <value type="bool">true</value>
  </binding>
  <mod-up>
   <binding>
    <command>property-assign</command>
    <property>/systems/submodels/trigger</property>
    <value type="bool">false</value>
   </binding>
  </mod-up>
 </button>


Then in your *-set.xml file you need to define a path to the configuration
file (similar to the way the electrical system is now done):

<sim>
 ...
  <systems>
   <electrical>
    <path>Aircraft/Generic/generic-electrical.xml</path>
   </electrical>
   <submodels>
    <serviceable type="bool">true</serviceable>
    <path>Aircraft/FW190/submodels.xml</path>
   </submodels>
  </systems>
 ...
</sim>


Then you put the submodel configuration file in your aircraft's directory.
I've attached a file, submodels.xml, that can be used to define a gun that
works just like the former one did.


There are two things remaining to be done.  One is to change the function
SubmodelSystem::transform() to properly position the submodel.  This will
require some complicated matrix code that I might borrow from Yasim.

be6936be80 Vivian Meazza:
Well here's some tracer stuff. If fiddled around with submodel.cxx. It now
does what it says - you need to put this:

<!-- trial gun system -->
    <systems>
      <submodel>
        <serviceable type="bool">true</serviceable>
        <amount type="int">120</amount>
      </submodel>
    </systems>

In the *-set.xml file NOT within <sim></sim>. Trouble is it still defaults
to serviceable=true, but it also defaults to amount=0. Unless this bit of
code is included it wont run, so other models can't fire inappropriate
tracer. Revised submodel.cxx file attached.

I've changed to a non-billboard solution. I tried to make the viewing angle
of the tracer less than 180 degs, but failed. Close enough I think. It's
still a bit big, but a reasonable compromise. .AC file attached.

I remain concerned about the tracer colour. In practice, red is better (and
it's what I am used to) but David seems set on white, and I don't want to
upset him. I'm going to adjust the texture a bit more tomorrow.

161912ea4c David Culp:
Right now the code is not very configurable, and there is only one submodel per airplane possible. It is implemented as an SGSubSystem, just like the electrics, vacuum, etc. systems.  To make it work you need to make a release binding like this (for my joystick trigger):

 <button n="0">
  <desc>Trigger</desc>
  <binding>
   <command>property-assign</command>
   <property>/systems/submodel/trigger</property>
   <value type="bool">true</value>
  </binding>
  <mod-up>
   <binding>
    <command>property-assign</command>
    <property>/systems/submodel/trigger</property>
    <value type="bool">false</value>
   </binding>
  </mod-up>
 </button>

Then, each airplane that uses the system should have something like this added to its *-set.xml file (note that this does *not* go within the <sim></sim> tags):

 <systems>
   <submodel>
    <serviceable type="bool">true</serviceable>
    <amount type="int">70</amount>
   </submodel>
 </systems>


Future improvements will include:
1)  more configurability, so the user can create multiple submodels, and can assign them different locations, and pitch and yaw adjustments, and nitial velocity.

2) sound?

3) a more accurate calculation of the submodels location at any pitch/roll/yaw.

4) a way to pre-load the model, so the AI code doesn't have to parse the model every time it creates an instance.

I think that's all of it.

5c18572c64 Melchior FRANZ:
All necessary elements for an ADF gauge had been migrated from
Cockpit/kr_87.cxx to Instrumentation/adf.cxx. Migrating the sound
related elements was apparently planned, but not done yet. This
intermediate state broke the ident morse sound: it couldn't get
turned off and it always indicated "SF", regardless of the tuned-in
frequency. The following patches continue the migration:


adf-radio.diff     => Base/Aircraft/Instruments/adf-radio.xml:
---------------------------------------------------------------
* sets maximum volume to 1 (rather than 2); Not only is 1
  loud enough (and 2 unpleasantly noisy), it also prevents
  the knob from being turned to non-existant positions.  :-)
* fixes wrong use of /instrumentation/adf/ident
* the voice/ident selector(?) remains unchanged, but as it's
  not switched to "IDENT", there'll be no ident sound by default
  this is consistent with other sounds and DME.


radiostack.diff    => src/Cockpit/radiostack.[ch]xx:
---------------------------------------------------------------
* comment out use of FGKR_87 class. kr_87.[ch]xx is now no
  longer used. kr-87adf.xml would no longer work, either, but
  isn't used anywhere, anyway. Future adf radios have to use
  the adf instrument, using xml/Nasal for specific hardware
  implementation details.


adf.diff           => src/Instrumentation/adf.[ch]xx:
---------------------------------------------------------------
* adds ident morse sound capability using two new input
  properties:
  - /instrumentation/adf/volume-norm  (double)
  - /instrumentation/adf/ident-audible  (bool)

5cd465354c Melchior FRANZ:
this was always only meant to be a test program for the metar lib, but now
that people are referring to it as a means to get metar reports, I think a
usage info is desirable. The list of test ids, on the other hand, isn't
necessary any more. This can still be handled by a Makefile or the commandline.
I'm all for keeping this tool in cvs, however. And also the not-used stuff
therein is a welcome source for how to use the SGMetar class.
