The general idea is to help clean up some aspects of the FDM init and be
able to provide startup conditions in a less ambiguous manner.
Previously, things like positions, orientations, and velocites were set on
"the bus". These had to be read by the FDMs which then were supposed to
initialized themselves to those values and turn write around and start
modifying those values. It was messy and cumbersome.
Now, all the initial fdm conditions are written to a sub-[property-]tree
under /sim/presets/
The values in /sim/presets/ always stay set to what the user has specified.
The user can change these at his/her liesure, and then request a "reset"
which will reset to the new conditions. I don't even want to say how this
worked before. :-)
Now, an script, or gui interface can stage a set of initial conditions while
the sim is running (without disrupting it), and then call "reset" to commit
the change.
People who should worry about all this are FDM writters, and a small few
others who care about over all program structure and flow.
duration-sec. This animation may have any number of child objects,
and each one will be displayed for the requested duration before
moving on to the next one.
Added Animation::init for initialization after children have been
added to an animation.
Added a default implementation of Animation::update, and removed all
of the empty ones in derived classes.
Removed tabs from model.cxx.
Indeed, there was no check for panel visibility in the input code. I
guess we've never noticed because nothing was fighting for the same
real estate in the past. This one-liner appears to fix the problem.
[also converted all tabs to spaces for Norm Vine]
That's a little too small to resolve differences at 16bpp. Try the
patch below. It decreases the lifting substantially. You will see
a slight increase in z-buffer flickering but it isn't bad. Note
that we removed the "distance" component the other day, the purpose
of it was to lift the lights higher when viewed at shallow viewing
angles. The distance component is critical for the street lights that
can be very long distances away.
But with the distances we're working with here it really doesn't
do all that much. The factor used in this patch is about as shallow
a lift as can be used when looking straight down at the airport. At
24bpp there's no effect from incorporating a distance component.
The choice is to reintroduce a distance component...one that works (and
only for 16bpp), or alter the factor used in the patch below to strike an
acceptable balance between different viewing angles when in 16bpp mode.
The biggest and coolest patch adds mouse sensitivity to the 3D
cockpits, so we can finally work the radios. This ended up requiring
significant modifications outside of the 3D cockpit code. Stuff folks
will want to look at:
+ The list of all "3D" cockpits is stored statically in the
panelnode.cxx file. This is clumsy, and won't migrate well to a
multiple-aircraft feature. Really, there should be a per-model list
of 3D panels, but I couldn't find a clean place to put this. The
only handle you get back after parsing a model is a generic ssg
node, to which I obviously can't add panel-specific methods.
+ The aircraft model is parsed *very* early in the initialization
order. Earlier, in fact, than the static list of allowable command
bindings is built in fgInitCommands(). This is bad, as it means
that mouse bindings on the instruments can't work yet. I moved the
call to fgInitCommands, but someone should look carefully to see
that I picked the right place. There's a lot of initialization
code, and I got a little lost in there... :)
+ I added yet another "update" hook to the fgRenderFrame routine to
hook the updates for the 3D panels. This is only required for
"mouse press delay", and it's a fairly clumsy mechanism based on
frame rate instead of real time. There appears to be delay handling
already in place in the Input stuff, and there's a discussion going
on about different mouse behavior right now. Maybe this is a good
time to unify these two (now three) approaches?
parts of the tree left over at the end which the failsafe was catching, but
this could impose a huge framerate hit if the missed portion of the tree
was large enough (and it very often was.)
rabbit lights appear to almost work except the last light or two is never
included in the animation and longer strings of lights are drawn as all
light on ... :-(
a tile boundary. (Potentially imposes a slight performance penalty, but
getting the correct answer needs to be higher priority than getting the
wrong answer really quickly.)
I noticed that textures for scenery static objects are not loaded
anymore for a few weeks. Static objects have absolute path while
random objects and aircraft have relative path but fgLoad3DModel
unconditionally prepend fg_root to the model path. This patch test the
beginning of the model path to choose if fg_root has to be prepended
to the model path.
Ok, I found the problem. You're computing the dynamic pressure in
"psf" and adding it to the static pressure in "inHg" to form the
total pressure. The attached patch is the simple fix to the source.
With that fix, failing the pitot while in cruise at 3k' will cause
the airspeed to indicate beyond redline during climb ... well before 4k'.
Thus, a pitot problem can be detected on any IFR altitude change.
Similarly, failing the static (with working pitot) while cruising 4k'
causes the airspeed to indicate beyond redline during a descent
well before reaching 3k' (during which, of course, the ALT looks fine).
Thus, a static failure can be detected before the aircraft breaks out
of the pilot tolerance range and is blatantly conspicuous soon after.
Now the options can be localized as well. This adds a slight problem for
the --language options, but not that much (worst case, the strings are
loaded twice consuming some more memory). I tried to be as accurate as
posiible when copying the options texts, but there might be some
mostakes left.
This adds supports for a language specific font, defined in locale.xml
I've also moved the fgInitLocale() routine from main.cxx to fg_init.cxx
to prevent an ungly extern definition in options.cxx.
are now working. A runway light is defined by a point and a direction. The
point and direction are combined with the local up vector to create a small
triangle orthogonal to the direction. The two ficticous corners of the
triangle are given an alpha value of zero, the orignal corner is given an
alpha of one. The triangle is drawn in glPolygonMode(GL_FRONT, GL_POINT)
mode which means only the corner points are drawn, and since two have alpha=0
only the original point is drawn. This is a long way to go to draw a point,
but it ensures that the point is only visible within 90 degrees of the light
direction, behind the light it is not visible. This is still a long way
to get to drawing a point, but we use an environement map, with the direction
vector as the normal to mimic a light that is brightest when viewed head
on and dimmest when viewed perpendicularly or disappears when viewed from
behind.
- warning, there is a bug in how the current runway light direction vector
is calculated which will adversely effect runway lighting. The airports
should be regenerated in order to fix this problem.
The FGGlobals constructor does not initialise the locale pointer.
Under MSVC, uninitialized pointer have a value of 0xcdcdcdcd, not
0, so a test in mainLoop fails and the program segfault.
This patch set un initial value to locale.
This patch fixes some bugs for correctly reporting un-updated
configuration files, and adds support for a --language=<code>
commandline option, overriding the language specified by the OS.
KEMT (w120n30 scenery), and you will have to set the property
/sim/ai-traffic/enabled to 'true' to see the other plane (and tune
comm1 to 121.2 to hear the other plane's radio calls).
For sounds that play while a value is in transit, use time rather than
the number of frames to judge when to halt the sound because it will be much
more reliable on high performance systems. It currently waits 10 ms.
before stopping the sound, but you might want to fiddle it a little by
changing MAX_TRANSIT_TIME defined int fg_sound.hxx
really see anything different in the day, but as day turns to night the
panel smoothly darkens and the lighting component becomes visible.
Lights are wired to electrical system so if you kill power, you lose the
lights.
The code reads the electrical system config and contructs an internal model.
Nothing is done beyond that yet ... the electrical system is not updated,
nor is it connected to the property system in anyway.
fgLoad3DModel() throws an exception if it fails to load the requested model.
This causes FGTileMgr::update(...) to exit. So I've added a try/catch block
to catch the exception and display an error message instead.
jump whenever you cross a tile, but there are currently a lot of other
positioning problems as well, so this doesn't really detract too much and
means you can play with 3d clouds from just about any starting point.
A bug lurked into our uiuc code.
There are two changes:
[1] Comment out the chunk of code as shown (compare w/ the old)
[2] Put back in the function call, and in that code change AlphaTail to Alpha.
Use getDisplayName instead of duplicated code: gives a better
decision on whether to display the index.
Replace unnecessary node lookups by name with direct access: tidier
and more efficient. E.g. "getValueTypeString
(node->getNode(name.c_str()))" -> "getValueTypeString (child)".
When the scroll bar slider is dragged, the list scrolls only far
enough to see all items; only the arrow buttons can scroll it so far
that the last item goes to the top of the view.
Fix scroll bar proportional size: was wrong when the list was only
a little longer than the visible area.
Minor fixes such as "delete files[i];" -> "delete[] files[i];"
(where the item being deleted is an array of characters) and removal of
global variables.
Smooth scrolling when dragging the slider: one item at a time,
rather than one tenth of the list at a time.
Fix a bug that would have occurred if instantiated with arrows=2.
Sort properties primarily by name and then by numerical index
order, rather than a simple ASCII string order. E.g. "js[1]", "js[2]",
"js[10]" rather than "js[1]", "js[10]", "js[2]".
Avoid crashing if the selected property path does not exist;
display an empty list instead. This cannot happen when the property
picker is working properly, but did happen due to missing indices prior
to this patch, and could happen if the user is allowed to type a
pathname, as in the http and telnet interfaces.
Fix truncation of strings to PUSTRING_MAX: was wrong when string
length was exactly 80.
Fix: move the scroll bar to the top each time a new list is
displayed. It was left at its previous position, while the top of the
new list was displayed, not corresponding to the slider.
Use getDisplayName instead of duplicated code: gives a better
decision on whether to display the index, and avoids invalid property
paths being generated which would previously crash find_props().
Replace unnecessary node lookups by name with direct access: tidier
and more efficient. E.g. "getValueTypeString
(node->getNode(name.c_str()))" -> "getValueTypeString (child)".
speedups to uiuc_menu.cpp.
(Note these were originally submitted before the cutoff date for new
features, but something was corrupted in the transfer so I granted a bit
of leeway in the schedule.)
