Change fgcommand to take an optional property tree root element.
This fixes the animation bindings to use the defined property tree root - to support multiplayer (or other) model that can bind to the correct part of the property tree.
Requires a corresponding fix in sg to allow the command methods to take an optional root parameter.
What this means is that when inside someone else's multiplayer model (e.g. backseat, or co-pilot), the multipalyer (AI) model will correctly modify properties inside the correct part of the property tree inside (/ai), rather than modifying the properties inside the same part of the tree as the non-ai model.
This means that a properly setup model will operate within it's own space in the property tree; and permit more generic multiplayer code to be written.
This is probably responsible for some of the pollution of the root property tree with MP aircraft properties.
The new FGLight::updateObjects() function is now being passed into the global
events manager as a task rather than FGLight::updateSunPos(). The
updateSunPos() function has been renamed to updateBodyPos() and generalised for
any solar system body and is called twice by updateObjects(), once for the sun
and once for the moon. The local position of the moon is then exposed at
"/ephemeris/moon/local/".
The functions fgSunPositionGST() and fgTimeSecondsUntilSunAngle() have been
renamed to fgBodyPositionGST() and fgBodyPositionGST() respectively, and both
require a new char argument specifying the body of interest. This allows the
position of all solar system bodies to be calculated from the aircraft frame of
reference.
Remove uses of .str(), .c_str() and some other methods of SGPath.
Pass SGPath directly where possible, or explicitly convert to the
appropriate 8-bit encoding.
- sim-speed-up (a/A keys) offsets warp correctly. This means at 4x speed
up the warp will increase by 3 seconds for one elapsed real second.
In practice this means simulation elements timed using sim ‘current time’
will be correctly synchronised with those using simulated elapsed time.
(AI traffic being a prime example of this)
- warp-delta (t/T keys) is independent of frame rate, and works when
paused. The warp-delta values in the keybindings / GUI dialog
will need to be updated since warp-delta in now seconds-per-second,
as opposed to seconds-per-frame.
- consistent with pause (freeze), /sim/speed-up is now applied to the
dt value for all subsystems, not just the FDM and some instruments.
For example AI traffic can now be sped-up or slowed down.
- requires both an FGData and Simgear update.
Configurable with properties:
/sim/time/warp-easing == false ? jump to new time offset (orig. behaviour)
/sim/time/warp-easing == true ? use easing parameter to adjust warp
/sim/time/warp-easing-duration-secs: time in seconds to reach the new value
/sim/time/warp-easing-method: easing method to apply. default: swing
Since d91a617423 (vectory color calculations)
all 4 elements of a color were scaled with the respective brightness.
The caused some panels to be transparent at night etc.
Before the change, only the 3 RGB elements of the colors were scaled,
while the 4th element (alpha channel?) remained unaltered.
Commit restores the alpha elements to their original behaviour.
=> "Quick hack" for 2.6.0. Need s.o. to double check the initial changes
and commit something clean to "next".
Commit 5f0066c resulted in an incorrect angle calculation. At certain view/sun
angles "hor_rotation" and "rf1" would skip from the minimum to the maximum
value).
Also, an offset angle of 90 degrees (PI/2) is added, which seems to align
the sky effect with the sun position. Calculation is probably still wrong,
but seems less wrong than before - and the flickering is gone...
Fog color became negative at certain sun angles (around midnight), which
resulted in weird sky dome coloring issues.
Hack: simply clamp the value for now.
Add range checks and provide error messages.
Extend time offset to 64bit - so we're safe for 2038-01-19 (and the next
couple of millions years beyond...).
Support partial date/time strings, such as --start-date-gmt=2011 or
--start-date-gmt=:::12:00:00
For use with frame rate throtteling make use of
SGTimeStamp::sleepUntil. This function should cover the
system dependent parts of accurate sleeps and should
move the system dependent code out of the time manager.
