This patch adds an "interval-sec" property which allows fixing an interval in seconds (or fraction of seconds) for the repeats for emulated axis controls (digital hats) on joysticks.
These patches add a clock instrument, which allows to model failure ("serviceable") and to adjust the time independently of the system time (defaults to GMT). The main incentive is to make the p51d clock work and adjustable via the knob.
o Offers a time string ("12:03:15") for the LCD or for LED
clocks, or an empty string in case of failure/power off. The
instrument assumes that digital clocks are battery buffered,
so they will be updated even if there's nothing on the display.
o Offers the number of seconds since midnight for analog
clocks, like in the p51d. This number is not increased
if !serviceable. So the clock will stand still and continue
where it stopped when it's serviceable again.
I did not consider voltage yet, because the Mustang's clock will need a lot more current than the LCD clock. The instrument is updated 4 times per second but returns immediately if neither time nor offset changed. The function getGMTString() in fg_props.cxx could be removed after applying these patches.
between temperature at altitude vs. temperature at sea level. The dialog
box asked for temperature at altitude which makes sense, but all the
internal crunching expected temperature at sea level. However, it makes no
logical sense to specify the sea level temperature for different layers so
I changed the internal processing to work with temperature at altitude and
then derive an approximate sea level temperature at the end.
If you know the ground temperature, you can just enter this temperature
for the first boundary layer and the system should do the right thing.
/sim/rendering/horizon-effect
toggle sun and moon resizing effect near the horizon
/sim/rendering/enhanced-lighting
toggle enhanced runway lighting on or off
/sim/rendering/distance-attenuation
add distance attenuation to the enhanced runway lighting
etc.
Improved the weather system to interpolate between different
elevations and deal with boundary-layer conditions. The configuration
properties are now different (see $FG_ROOT/preferences.xml).
This version handles a zero fuel load better. I found that if you try to consume fuel from an empty tank, with zero fuel flow, the FGEngine::Starved flag alternates
