This is a clean up commit prior to the subsystem API standardisation to simplify
the diffs. It includes all SGSubsystem and SGSubsystemGroup derived classes.
Upcoming flight-planning changes want to use the perf computation code
in route-path, so move it to a public class, and implement some of the
missing functionality, especially correct GS computation for altitude.
This change is the logical counterpart of SimGear's change from commit
79f869a7f32910197be72b21f6489fbbba02c836 that moved the following files
from simgear/misc to simgear/io/iostreams:
gzcontainerfile.cxx
gzcontainerfile.hxx
gzfstream.cxx (formerly zfstream.cxx)
gzfstream.hxx (formerly zfstream.hxx)
sgstream.cxx
sgstream.hxx
sgstream_test.cxx
Requires FGData commit: 0565eaab10a5d466cd485766b17d1870936a0a57
(which actually renames the file).
Also disables the preferences-load command since I don’t believe it
would actually be safe to reload the defaults without doing a simulator
reset (aircraft -set.xml values would be overwritten, for example)
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.
- 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.
When using the default (generic) config, which references many props which may not exist in a particular aircraft, suppress the 'recording non-existent' property warning.
Record the historical flight-path (by default, since last takeoff). Optionally display the flight-path in the map; other visualisations (e.g., an 'in-world' view) could also be created. Nasal API to follow so Canvas-map or FMS can show the same data.
Altitude and attitude (Euler angles) are currently recorded but not used anywhere.
FGControls create/init/bind order was incorrect, causing initial property tree state to get over-written. Restructure the code so bind() sees correct values.
- move property /sim/auto-coordination to
/controls/flight/auto-coordination
- introduce new property /controls/flight/auto-coordination-factor
with default of 0.5
- auto-coordinate the rudder if auto-coordination is true and the factor
is greater than zero
backward compatibility for the old property is temporary provided by
a temporary Nasal hack in FGDATA/Nasal/aircraft.nas
