I've done some substantial reengineering of the 2D panel: except for the
radios, the whole panel is built from a large table now. I'd be
grateful if you could add these changes to the main distribution.
Since I always like to provide some eye-candy with my updates, I've
fixed the ADF gauge to be more usable by slimming the needle and adding
markings every 45 deg (you'll need to use the attached textures).
- the panel uses much, much less texture memory, and draws much
faster, at least on my hardware
- there is a wet (magnetic) compass at the top of the panel
- the gyro compass shows true heading again, but don't get used to it:
we're going to set it up to drift soon
- there are TO/FROM flags on NAV1 and NAV2 (but no GS flag yet)
- the ADF looks a little more realistic (if you can forgive the ugly
needle)
- when the HUD is not open, the framerate is moved to the right side
of the screen so that it won't be obscured by the mag compass
- knobs now continue to rotate when you hold down the mouse
- the middle mouse button makes knobs rotate much faster
- there are NAV1, NAV2, and ADF radios that can be tuned using the mouse
- there are standby frequencies for NAV1 and NAV2, and buttons to swap
- there is a crude, rather silly-looking DME, hard-wired to NAV1
- there is a crude, rather silly-looking autopilot that can lock
the heading (to the bug on the gyro), can lock to NAV1, and can lock
the current altitude
- the knobs for changing the radials on NAV1 and NAV2 look much better
and are in the right place
- tuning into an ILS frequency doesn't change the displayed radial for
NAV1
Code
- I've created a new module, sp_panel.[ch]xx, that constructs the
default single-prop panel; this works entirely outside of FGPanel,
so it is possible to construct similar modules for other sorts of
panels; all code specific to the default panel has been removed from
panel.cxx
- current_panel is now a pointer
- radiostack.[ch]xx keeps track both of the actual radial and of the
selected radial (they will differ with ILS); the NAV gauges should
not spin around automatically to show the actual radial (we need to
do something similar with the autopilot)
- the panel is initialized fairly early
- make sure that standby frequencies also get initialized
- I've started combining and clipping small textures to save texture
memory; there's a lot more to do, but at least I've made a start
old routines from SRGP. Steve's plib/sg.h does a nice job of completely
replacing this (and since plib is already around) and is a nice clean design
so it just makes sense.
