Recording of extra properties is only supported in Continuous recordings.
Modified Continuous recording format to allow future forwards
compatibility. See docs-mini/README-recordings.md for details. This breaks
compatibility with previously-generated Continuous recordings, but this only
affects next.
To reduce overhead we record all extra property values in the first frame and
then later frames contain only extra property changes. When replaying, if the
user jumps backwards we replay all extra property changes since the start of
the recording. Similarly if the user jumps forwards, we replay any intervening
extra property changes.
Recording extra properties:
This is enabled by:
/sim/replay/record-extra-properties
The extra properties that are recorded are identified by the property
paths in the values of /sim/replay/record-extra-properties-paths/path[]
properties. We record the entire tree for each specified path.
Recording of main window position size:
We have specific support for record and replay of main window position/size.
This is enabled by:
/sim/replay/record-main-window
Recording of main window view:
We have specific support for recording the view type and direction/zoom
settings.
This is enabled by:
/sim/replay/record-main-view
We record the /sim/current-view/ property tree, excluding some subtrees
that continuously vary but are not required for replaying of the view.
When replaying, we allow separate control of what extra property changes are
replayed, with:
/sim/replay/replay-extra-property-changes
/sim/replay/replay-extra-property-removal
/sim/replay/replay-main-window-position
/sim/replay/replay-main-window-size
/sim/replay/replay-main-view
We work around some problems caused by the use of tied properties when
replaying changes to view-number.
Window position issue:
When replaying window position and size changes, things get a little tricky
because osgViewer::GraphicsWindow::setWindowRectangle() takes a position
for the entire window, but osgGA::GUIEventAdapter::RESIZE events contain
the position of the interior of the window; for example the y values will
differ by the height of the window's titlebar. This can cause windows to
move progressively further down each time they are positioned or resized.
There doesn't seem to be a way of finding the size of a window's
furniture directly. So instead this commit adds a new method
osgGA::GUIEventAdapter::setWindowRectangleInteriorWithCorrection() which
wraps osgViewer::GraphicsWindow::setWindowRectangle(). We listen for the
following osgGA::GUIEventAdapter::RESIZE event and calculate corrections
for x and y position that are used for subsequent calls.
docs-mini/README-recordings.md:
Updated to document new Continuous format.
scripts/python/recordreplay.py:
New script to test various aspects of record/replay.
Other:
We now create convenience softlink to most recent continuous recording, using
SGPath::makeLink(). Note that SGPath::makeLink() currently does nothing on
Windows.
Changed format of Continuous recordings to contain a single property tree
in header. This is much simpler than having separate Config and Meta trees.
It was supposed to be in ft/min, but everything except AIAircraft was
using it as ft/sec. Change the name to AIBase::vs_fps and ensure the
same unit is used everywhere.
QML implementation of getting started tips, with a nice styled
background box. Tips are defined+positioned inline, and displayed
when their enclosing scope is active.
Translocation forces us to rebuild the nav-cache each launch, and might
mess up some other details, so let’s warn the user they should copy
the app to Applications or similar.
If the user double-clicks, and their system is slow, the action can
fire twice, which then breaks because we add options twice.
Sentry-Id: FLIGHTGEAR-HKV
Move forward 1 metre in tower view look from, to slightly improve view of
ground near tower.
Removed incorrect attempt to move towards target in other tower views, that
didn't work.
This means that the image on screen moves by the same distance as the mouse
(for small movements), regardless of window size or zoom level. Current mouse
drag handling in extra view windows is poor though - mouse is constrained by
screen size.
Would be good to do this for standard views as well, but the code in view.cxx
is more complex so haven't been able to figure out how.
Allow the option to have the marker beacon instrument use either the
correct timing, or ‘always on’ when the beacon is in range. Try to
ensure the audio is synchronised with the visual property. by using
the same timing values.
Also avoids losing sync when using the ‘audio-btn’ toggle, and increases
the update rate to allow accurate timing. Finally, switch from tied
properties to regular ones, so listeners on the beacon properties are
updated directly.
Configure the VPB elevation mesh via properties:
/scenery/elevation-mesh/sample-ratio controls the elevation
mesh sampling, allowing reduction in mesh size
/scenery/elevation-mesh/vertical-scale is just for fun and
scales the mesh vertically making mountains taller.
/scenery/elevation-mesh/constraint-gap-m controls how much below
airports etc. elevation vertices are forced to be.
