This tests
* basic functions of register/degregister
* ensures that transmit/receive work correctly
* Transfer encoding methods (byte, double, norm, int) work properly
This is a normal transmitter than doesn't act synchronously and instead queues messages for future processing.
Can be useful to implement thread safe receive/transmit logic where a sub thread is requiring property changes that can be sent to a queued transmitter that is then processed in the main thread.
Make listeners for MP properties only fire when properties changes.
Enherit the notification before propagating to avoid StartMessageIndex being shared and thereby messages can get held back.
Some improvements to logging.
Control the order in which fgdata/Nasal/*.nas files are loaded
on startup.
Previously all the files were loaded in order based on filename.
This was problematic for aaa.nas which might want to call
props.getNode(), and generally resolved by using
_setlistener("/sim/signals/nasal-dir-initialized")
This change allows us to configure a list of Nasal files that are
loaded first on startup - loadpriority.xml.
Fix bug https://sourceforge.net/p/flightgear/codetickets/2219/
Changes to logging mean than setlistener breaks when invoked via
call(), which occurs in the Warthog Nasal scripting. The problem is
that call() forces caller() to return nil, which the setlistener()
debug code did not check for.
When more than one message type being transmitted on the bridge only one of the types would be reliably received. Bug caused because the message index is per notification type (on MP bridge outgoing) but was being treated as per incoming bridge (rather than notification).
Implement the Nearest Airports PFD softkey, displaying a scrollable
list of the closest 25 airports within 200nm.
Also fix a couple of minor bugs and add self-checking to the
GroupElement
Previously the FG1000 and MFD assumed that all notifications received
via Emesary had a Device_Id field. This is true for
notifications.PFDEventNotification.DefaultType but not for other
messages - e.g. those generated by the AN SPN 46 system on the
carrier.
The effect of this was that when Nimitz was loaded, the FG1000 stopped
working with various errors.
This fix checks the notification type before the Device_Id.
The method horizon() returns the distance to the horizon, along earth
surface, starting from current location. The method
greatcircle_distance_to(A,B) returns the shortest distance to a great
circle passing by A and B, along earth surface and from current location.
In conjunction with some FlightGear changes, the delegate can now do
all sequencing decisions, i.e the GPS C++ code does not make any policy
decisions about sequencing.
Update the default Nasal delegate to mimic the old behaviour, and set
the config option, both to allow future developments and to demonstrate
the new API.
It looks like widgets don't inherit font or colour from parent widgets. Also,
setting font=nil gives sublety different results compared to leaving font
unspecified.
So we now set font and colour explicitly for every widget using new function
set_default().
Also set font and colour of 'Pilots:' widgets and heading widget to me.fg[1] to
match other text.
resetViewPos(): set /sim/current-view/?-offset-m to
/sim/view[]/config/?-offset-m, not zeros.
This requires corresponding change to flightgear to compensate for the extra
offset, and fixes things when aircraft implement custom views by writing to
/sim/current-view/?-offset-m.
It's always been at the top; and although it is clear that the intent of this change was to improve things it highlights the need to make more substantial improvements to the way on screen messages are handled.
What we probably should have is an area that has a transparent dark background, a fixed size, supports scrolling, can be left open (or re-opened) and moved persitently around the screen.
This reverts commit 82f3eb45b9.
Due to Nasal/view.nas making a sequential copy of views, inserting new view
number 8 for Tower View AGL broke custom views, e.g. for aircraft 777).
We no longer require Model View (it's identical to Helicopter view now), so
this way we can have Tower View AGL without altering sequential view numbers.
I think the previous alternating colours were confusing because of the use of
a third and fourth colour for when we have no model or are using a fallback
model.
I think this is more convenient than the normal model-view buttons / popup
list. [Though this is still there.]
Nasal/multiplayer.nas:
Added new column 'view' with checkbox. Also added 'view self' button to
titlebar to view the user's aircraft.
Fix some bad indentation.
Nasal/view.nas:
Changed /sim/current-view/model-view to contain just the callsign, not
'<callsign> <model>', so that Nasal/multiplayer.nas can get the callsign
reliably.
We remember the multiplayer aircraft so that when switching between views,
multiplayer views (currently Helicopter, Model, Tower and Tower AGL) show the
same aircraft.
Nasal/view.nas: use /orientation/true-heading-deg in Model view and Tower AGL
view. This avoids problem when looking at multiplayer aircraft because there is
no /ai/models/multiplayer[]/orientation/heading-deg
Nasal/view.nas: improved handling of sim/current-view/{x,y,z}-offset-m. Changed
resetViewPos() to set these all to zero, because view's offsets are now
kept separate. Also removed setting of /sim/current-view/z-offset-m to
chase-distance - this is the wrong place now that views define the offset
explicitly.
Also added Tower View AGL support.
- This will alert if any individual notifcation takes more than a certain amount of time to process.
Works well with the Emesary M_exec to identify where the slow parts of Nasal are.
Only the selected channel will now be used for PTT; however the bindings still selected the appropriate channel prior to setting PTT.
This provides a compatible solution that can also easily be bound to the (joystick) controls.
PTT now in
/controls/radios/comm-ptt as an int; non zero indicates which comm radio to use
/comm-radio-selected is the default comm channel to use. This should usually be the same as will be set by PTT into /controls/radios/comm-ptt
NOTE: that PTT will switch the FG comm inbound and outbound frequency to whichever radio was PTT'd.
+ After discussion with Henning:
- orig_setlistener() and orig_maketimer() were not intended to be
public -> prefix the function names with an underscore;
- clear the add-on's lists of tracked listeners and timers in
remove() (load() does that too, but it's a bit late).
+ Little rewording in Docs/README.add-ons.
Without this it will cause a nil dereference resulting in
Nasal runtime error: non-objects have no members

Trigger sets /controls/armament/trigger - typically for a gun, but can be used (model side) to launch anything
Pick sets /controls/armament/pickle - typically to release something (e.g. missiles), but could be bound model side to act as a trigger.
Definitely problems in aar.nas, seaport.nas; as these were hanging off a fdm-initialized.
The others have timers that are started from a listener and as such are more suited to use maketimer rather than settimer
The modules that use the loopid technique are probably fine, but these are also more suited (and easier to understand) using a maketimer
- modify to work with JSBSim aircraft when reloading the fuel based on the payload (e.g. external tanks selected)
- add property sim/gui/dialogs/payload-reload that when set will cause the payload dialog to reload (to support a second dialog that modifies the payload)
- fix so that the window retains its position (close handler) and window Z order when reloading.
- added extra bindings
- reworked the view axis (usually bound to the hat); to move at a better rate.
- trim to elevator position. When selected this will remember the current position and when the joystick is centered it will apply this as the trim. Very useful for carrier approaches; and also it helps to do something that is much easier with loaded controls when you can feel the pressure being reduced by the operations of the trim switch
Checklists now support grouping by placing a group of checklists
under a <group> node.
e.g. /sim/checklists/group/checklist
The group can have a <name>, which is used by the checklist dialog
and can be used by other interfaces, such as the FG1000.
- Engines control now use the same axis methods as the flight controls; which allows for these to have an inverted checkbox.
- Change the axis combo boxes to instead show a popup dialog (much like the button config). This is better because the items can be grouped sensibly.
- Changed the way that the "all engines" controls work - the dialog binds these to a "engines/XXXX-all" for which there is a listener in controls.nas which propogates over all engines.
- Added extra bindings to both the buttons and the axis dialogs.
- moved the "None" button to the bottom and renamed it to the more comprehensible "Remove assignment"
The add-on framework now uses the following files in each add-on
directory:
- addon-config.xml (previously: config.xml)
- addon-main.nas (previously: main.nas)
This is consistent with the addon-metadata.xml file that is already part
of the interface between FG core and add-ons. The goal is to make it
clearer, when browsing an add-on directory, which files belong to the
"FG core <-> add-on" interface and which files belong to the add-on
proper. This will be beneficial also when more files are added to the
"FG core <-> add-on" interface, such as possibly addon-events.xml in the
future.
This change is incompatible, thus it is the right time to do *before*
2018.2.1 is out, especially considering that this upcoming release
already has incompatible changes in the add-on API, namely the
requirement of the addon-metadata.xml file and the type of the argument
passed to each add-on's main() function. We'll try harder not to break
compatibility in the add-on API once 2018.2.1 is out. For now, it is
still a good time to try to get the API as clean as possible.
Change /sim/multiplay/transmit-only-generics to /sim/multiplay/transmit-filter-property-base, which can be 1 to transmit only generics, or a number greater than 1 to indicate the start index to transmit (e.g. 12000 for new emesary mp bridge properties)
ConfigStore for storing and retrieving config settings (needs XML import/export)
Header display with 4 different header fields (all configurable)
Publisher for ADC and FMS.
The addons.Addon instance (ghost) is much more interesting than its base
path. The base path is immediately accessible from the addons.Addon
instance using its 'basePath' attribute. The addons.Addon instance
allows main() to easily access essentially all of the add-on metadata,
including the add-on identifier, which makes it possible to write
main.nas without hardcoding the add-on id at all.
This is an incompatible change of course, so better do it now than
later.
- Add new Emesary notification type for NAV/COM data
- Create Update/Publish interfaces using Emesary from properties
- Use interfaces to drive updates to EIS and NAV/COM frequencies
- Change the PageGroupController to a "proper" MFD page
- DTO MapStructure layer to provide a DTO line to a lat/lon
- Support for scrolling lists in the PFD/GroupElement
- Support MAP (NavigationMap) and ENGINE (EIS) soft-keys from other pages.
By separating out the bridges this could be used in the future to transmit Emesary properties at a different rate. It is one of the future possible methods to improve MP communications and dual/multi controls
Also:
- use the namespace __addon[ADDON_ID]__ when loading an add-on's
main.nas file (previously, the namespace used was __addon[i]__ where
i is 0 for the first registered add-on, 1 for the second one, etc.);
- use logprint() instead of printlog(), because the former writes a
more helpful source file and line number for the log call in
fgfs.log (i.e., not always src/Scripting/NasalSys.cxx...);
- remove the listener once it has been fired;
- add documentation in Docs/README.add-ons.
A GeoEventNotification can be used to notify all other MP craft (that are connected to the bridge) of AI objects or ballistic items that are present on the local player's machine. For example tankers, dropped payloads, missiles, carriers.
Changes
- Fix transfer string encoding for bridge. If the string contained untransmittable characters the length was wrong. Change to use the valid characters from BinaryTransfer.
- Fix bug transferring negative numbers.
- Add method to notification to provide the type key to be used to decide if a non distinct message should be added to the queue; rather than relying on the simple type.ident. This allows multiple notifications of the same type to be non distinct but also be transmitted
- Allow the maximum size of the mp string to be defined per bridge; rather than a system wide value. This allows the bridges to have their size tuned to match expected requirements; for example a bridge that is transmitting GeoEventNotification may need a lot more space than a bridge that is transmitting property sync notifications.
- Improve error message when out of space (due to the maximum string length)
- add trace option to bridges to aid debugging of transmitted values. This will produce verbose output.
- Add UniqueIndex to GeoEventNotification; to allow for multiple non-distinct notifications to be transmitted concurrently. This overrides the GetBridgeMessageNotificationTypeKey to include the UniqueIndex
Allow a MFD to be controlled via Emesary notifications (notifications.PFDEventNotification);
Notification needs to be constructed with the following parameters;
1 - MFD designation (text; name of MFD)
2 - MFD identity (int, id of the MFD within the model). Default 1; same as used when creating the MFD
3 - Event type (PFDEventNotification.SoftKeyPushed, notifications.PFDEventNotification.ChangeMenuText
4 - Event parameter.
a) for PFDEventNotification.SoftKeyPushed an int identifying the button
b) for notifications.PFDEventNotification.ChangeMenuText a hash array containing the menu ID and the new text (e.g. [{ Id: 1, Text: "NNN"}])
Method obj.PFD.RegisterWithEmesary(emesary.GlobalTransmitter) need to be called to connect the MFD to a transmitter
Change fonts; make use of the new feature to allow fonts to be specified using property from dialog xml.
Ensure that all fonts are defined within the style.
