* <function> and <fcs_function> that are only applied on constant parameters are now recognized and replaced by their result during initialization.
* Fixed a regression which prevented the wheels rotation speed to slow down while the gears were retracted.
* Added the ability to control the turbine engines spin down factor (thanks to Jonathan Redpath for the pull request).
* Internals : JSBSim has been refactored to use FGPropertyValue in many FCS components. This will allow consistent behavior accross the FCS components including the ability to prepend property names with minus signs '-' to indicate that the opposite sign of the property should be used.
lag compensation, this is the time manager part.
- introduction of a pure steady clock initialised from system clock at init
- the mp protocol clock have an offset available (will be used
to sync the players, in case ntpd is not accurate or inavailable)
- got a way to see drift between system clock and the fg steady clock, mainly
to see how differents OS behave ...
The problem was using FLT_MAX, FLT_MAX to disable a model; this tricked OSG into thinking that FLT_MAX was a valid range and therefore didn't do the update traversal (found by Stuart).
The correct technique to disable a model is to set the min/max range to 0,0
Also generally improved the way that the ranges are managed.
Maps foo=bar arguments to the top-level arguments dictionary of the
command, as strings only. (We could add CMake style foo:type=bar in
the future if needed). Very basic but this enables a bunch of useful
cases, since SGPropertyNode will do value conversion from string on
access.
- avoid updating the formatted frequencies each update()
- reset the station search timer when frequencies change
This should make the radio a bit more responsive (which aids testing
since we don’t need to wait for the search timeout when changing
frequencies)
- pass texture cache control properties to simgear
- /sim/rendering/texture-cache/cache-enabled
- /sim/rendering/texture-cache/compress-transparent
- /sim/rendering/texture-cache/compress-solid
- /sim/rendering/texture-cache/compress
- support --texture-cache-dir command line option
- set max reported supported texture size during splashscreen.
If a model is marked as <usage>interior</usage> there were a number of problems.
1 - the LOD setting AI/MP interior used the distance from the aircraft; this obviously doesn't quite work for when using the model view.
2 - with the way that models are now loaded as two LOD levels only the interior from the first model loaded (usually the lowest detail) would be considered or processed because the model loader had marked itself as already run (which it had, but not for the model that was actually just loaded.
(2) above could also be the cause of other things not working because the nasal model loaded would not be called, nor would the sound path be setup. There could be other things that aren't working properly because the assumption is that there is just one model.
The fix for (1) is to use the standard OSG PagedLOD and let it handle the details, so I've changed the interior to use this and removed the distane from ownship checks.
The fix for (2) is to use a map to decide if the model that has just finished loading has already been processed, and if not then proceed as normal.
Change the single model case to always set the range on the only model rather than the constant modelHighDetail. This is a regressions caused by the change from 0 to modelHighDetail and the reordering the list. When there is only one model the setRange must always refer to model range index 0.
- This could have caused models to not display correctly.
The feature fail_hardover of the <actuator> component was not giving the correct output in some occurences when clipmax was smaller in absolute value than clipmin.
Tables CORNERING_COEFF could not be used for BOGEY contact points.
No longer throw an exception when the `internal` keyword of a table is ignored.
The location where errors have been found are now reported.
Rework the LOD ranges.
1. The scenery ranges are now deltas (avoids overlapping values)
2. The AI/MP pixel mode now has a default radius that is 20 for Aircraft, 200 for ships, 350 for carriers. This is a simple constant in a virtual function.
3. Added the ability to set the AI/MP ranges equal which means use the low detail model.
4. Changed high detail only to be indicated by a -ve number in maxRangeDetail
5. Re-ordered the range list to go from lowest detail at [0] to highest detail at the end. This is because OSG always loads the models starting from zero on the assumption that the detail increases with the index.
This fixes the pixel mode, which previously would use the radius of the parent which would be confusingly large, and unrelated to the actual size of the model. With the simple defaults that we have the pixel values set in the ranges won't exactly match the rendered size of the model on screen, but it will be a lot closer and more importantly meaningful.
The following new features have been added to JSBSim:
* Added the ability to set up the starter and acceleration times of a turbine (parameters <n1spinup>, <n2spinup>, <n1startrate>, <n2startrate>).
* The <integrator> filter can now be reset to 0.0 by setting its <trigger> property to a negative value.
* The integration scheme of the <integrator> filter can now be chosen among "rect" (Euler), "trap" (Trapezoidal), "ab2" 2nd order Adams-BashForth and "ab3" 3rd order Adams-Bashforth
* The following functions can now be used in <function>: floor, ceil and fmod. Their functionalities are the same than the corresponding C/C++ functions.
The following bugs are fixed by this commit:
* PID integration with the 3rd order Adams-Bashforth was inccorect.
* The fail_stuck property of sensors (accelerometers, magnetometers, gyro, etc.) without a <lag> element was setting the output to zero instead of sticking to the last output value. Thanks to Jonathan Redpath (aka legoboyvdlp) for the bug report.
* When a sensor was stuck, the drift, gain, bias and quantization of the last output before being stuck were ignored. Thanks to Dennis J. Linse for the bug report.
Due to how the popup menu was refresh, using MP servers at index 0 or 1
didn’t work correctly. Change some logic and add a helper to make this
work reliably, without a second Repeater and dummy properties.
