I have been running a version of John's models similar to this patch for several weeks with no issues. I will do a "replace" of atmo with atmosphere.

[Flightgear-devel] New Nasal in CVS
A big heads up. I just updated the Nasal interpreter to sync it with Nasal CVS: > Sync with Nasal CVS (soon to become Nasal 1.1).

This almost certainly broke something, somewhere. Please be on the lookout for anything that looks like it might be an interpreter bug or new behavior. Likewise, let me know if any platform builds broke -- at the very least, MSVC project files are going to need to be updated for the new files. Andy - Take Surveys. Earn Cash.

Yeah, that's now redundant. It wasn't until a few hours ago. Didn't
look at that.
> if (capacity - lbs >= fuel_per_tank) {

True. No idea where this comes from.
> Also, I think there might be a bug here: fuel_per_tank is a negative number!
Sheesh. Will check. This file was converted from an older version,
and apparently I added a few extra bugs. Thanks for reporting.

Re: [Flightgear-devel] Generic aar.nas/AI properties
Hi!
Looking at aar.nas I noticed some seemingly unnecessary elsif usage,
wonder if they are there for a reason:
if (size(selected_tanks) == 0) {
} elsif (consumed >= 0) {
} elsif (consumed < 0) { <=== HERE
}
... and ...
if (capacity - lbs >= fuel_per_tank) {
} elsif (capacity - lbs < fuel_per_tank) { <=== HERE
}
Also, I think there might be a bug here: fuel_per_tank is a negative number!
Thus the first condition will always be true. As we are in the
refuelling branch, I think it would make the code more readable if a
positive fuel_per_tank was used.
Another minor problem: during refuelling if one of the tanks fills up
in the current iteration, the extra fuel will not be distributed among
the other tanks. As this function is called often and thus processes
small amounts of fuel at a time, this does not really make a
difference. (Plus the tanks will usually fill up at the same time.)
Might be completely wrong, don't hesitate to kick me :)
Greets,
Csaba

[Flightgear-devel] nasal development news
I have today added/finished two simple features that are
interesting for development of Nasal code.
(A) Help->Nasal Console
This dialog supports now several tabs, of which each can hold
separate Nasal code snippets, all of which are saved on exit
and reloaded next time. This is useful for little tests, or for
executing code for which writing a key binding is just too much
work, such as "props.dump(props.globals)". It's easy to add more
"tabs" (= radio buttons). One just needs to add more nodes
to autosave.xml.
(B) (re)loading Nasal modules at runtime
There's a new function debug.load_xml_nasal(), which loads an XML
file with embedded Nasal into a nasal namespace. For syntax
coloring reasons one may want to use a *.nas extension for this file.
Example:
$ cat $FG_ROOT/Aircraft/foo/test.nas
$
One can now edit this file and import the code into fgfs with
this line in a key binding or typed into the Nasal Console dialog:
debug.load_xml_nasal("Aircraft/foo/test.nas");
This will load the Nasal code from Aircraft/foo/test.nas
into namespace "test" and execute it, so you'll see the message
"hi!" on the terminal, and have function "test.hello()" immediately
available. You can at runtime change the Nasal file, and import
again, etc. And once you are happy with the code, just remove the
two XML lines and load the file via classical method.
The namespace, to which the code is loaded, is determined from the
file name. foo.nas or foo.xml will be added to namespace "foo".
The namespace gets created if it didn't exist. Alternatively, one
can define a namespace in the file by addind a name:
whatever

Fixed. This was a bug in aar.nas, that was triggered by the B-2 occasionally not consuming *any* fuel between two loop runs, which seems to be a bug elsewhere ... m. - Take Surveys. Earn Cash.

[Flightgear-devel] Generic aar.nas/AI properties
Hello all! First off, when linking the B-2(yasim) to the generic aar.nas I experienced a constant switching of the engines/out-of-fuel property which unsurprisingly results in low thrust. Could this be related to the broken fuel-consumed-lbs property (of yasim?) that is jumping around close to zero? Secondly, is "live" manipulating of AI model properties possible at the moment? In the flightgear property browser I found orientation/true-heading-deg and some radar properties but I think it would come in handy to be able to manipulate speed, altitude and waypoints (and maybe more Wink) for an AI model. So it would be possible to "spawn" an AI tanker at a desired location or be able to launch testbeds or rockets from a plane and direct it to a desired location. I am using an end feb build of osg/fg. Maybe I missed something, thanks in advance, markus - Take Surveys. Earn Cash.
