Currently this works for all the default views except for Tower Look From (for
which it doesn't really make sense) and Fly-by View.
We now search for and load a -set.xml that matches the model .xml,
when new multiplayer aircraft is set up. This allows us to find view
offsets etc, e.g. allowing cockpit and helicopter views to work with
multiplayer aircraft. Properties from the -set.xml are placed into
/ai/models/multiplayer[]/set, so for example viewing offsets are in
/ai/models/multiplayer[]/set/sim/view[]/config/target-{x,y,z}-offset-m. We also
copy the aircraft's chase-distance into the view config params, similar to how
fgdata:defaults.xml does for the user's aircraft. And we also fill in views'
missing offsets from the Helicopter View config; e.g. this enables the new
Tower View AGL to show aircraft correctly centred, despite aircraft currently
not having this view defined in their -set.xml. [We don't currently attempt to
cache or reuse -set.xml data.]
Have ensured that view position responds to mouse movement in the same way for
viewing the user's aircraft as for multiplayer aircraft (previously, Model View
reversed the affect of vertical mouse movements).
Added new Tower AGL view. Behaves similarly to Tower view, but automatically
scales and pans vertically in order to always show the vertical range
extending from just above the aircraft down to the ground immediately below
the aircraft. We use aircrafts chase-distance as an indication of size. We
damp the ground level value to reduce the viewing jumping around too much
e.g. if the aircraft flies over buildings. The amount of damping is set by
fgdata:defaults.xml's lookat-agl-damping value.
Fixed problem where Tower View eye position moves slightly as target
aircraft heading changes. This was caused by us unnecessarily applying the
aircraft-centre correction to the eye position.
src/FDM/flight.cxx: also make /orientation/true-heading-deg. This allows
local orientation to be used like multiplayer orientation, which only
has /ai/models/multiplayer[]/orientation/true-heading-deg. [A better fix
might be to replace all occurrencies of /orientation/true-heading-deg with
/orientation/heading-deg, but this would be a rather large commit.]
Details:
src/Viewer/view.*: removed View::updateData() as is no longer required.
src/MultiPlayer/multiplaymgr.cxx: use helicopter view target offsets as
defaults. E.g. in tower view agl, aircraft won't currently be defining these
offsets. More generally, this allows aircraft to define target offsets only in
helicoter view.
src/FDM/flight.cxx
FGMultiplayMgr::FillMsgHdr(): Added tie of /orientation/true-heading-deg to
get_Psi_deg, so it duplictes the existing /orientation/heading-deg.
src/MultiPlayer/multiplaymgr.cxx
src/MultiPlayer/multiplaymgr.hxx
FGMultiplayMgr::addMultiplayer(): look for and load -set.xml that matches
the model. Patch various view-related things up in similar way to what we
do for the user's aircraft, so that multiplayer views work.
Made FGMultiplayMgr::getMultiplayer() public, so it can be used by
src/Viewer/view.cxx.
src/Viewer/view.cxx
src/Viewer/view.hxx
View::View(): Added lookat_agl, lookat_agl_damping params for new Tower
View AGL. Preserve user's field-of-view in separate variable so that Tower
View AGL can modify the actual field of view independently.
Added view_index param so that we can find multiplayer view[]/config/
properties.
getViewOffsets(): new fn that finds view offsets for user aircraft or
multiplayer aircraft.
View::recalcLookFrom() View::recalcLookAt: Lots of changes to allow things
to work with multiplayer aircraft. View::recalcLookAt() can now do Tower
View AGL.
View::Damping: support for damping, used by Tower View AGL. Might be good
to use this for other damping.
View::updateData(): removed, as calculations are now all done inside
View::recalc*().
put properties {x,y,z}-offset-m into new View::_adjust_offset_m member
instead of _offset_m. This avoids confusion between a view's offsets and
the offsets added in by the user via the 'Adjust View Position' dialogue.
src/Viewer/viewmgr.cxx
FGViewMgr::init(): pass view number to
flightgear::View::createFromProperties().
