Dispatcher scripts that route trains at a station based on where they
go afterwards (e.g. a big terminal throat with several outbound
directions) have no way to read that: whois +40 only exposes the
current/next timetable entry (NextStop()/IsStop()), which while the
train is at that very station is that station itself.
Adds flags::whois_ahead (bit 6, previously unused) plus
TTrainParameters::StationNameAhead(Offset)/StationIsStopAhead(Offset),
returning the raw TimeTable[] entry Offset positions past StationIndex
(name and whether it's a booked stop, "none"/false past the end of the
timetable). The new whois branch calls both with Offset=1, mirroring
the existing +40 branch's UpdateValues()/WriteLog() shape.
Logic-verified with an isolated harness mirroring the touched types
(TTrainParameters/TController/TMemCell shapes and the exact function
bodies); not yet build-tested against the full engine locally - relying
on CI for that.
When the Autorewident function is enabled, the EP fuse switch will no longer automatically engage or disengage if the player is controlling the train. This would happen for example when approaching a station.
MS DXC on Windows (at least IDxcUtils::BuildArguments) does not support forward slashes in UNC paths. This change feeds it native format with backslashes.
This makes it possible to build Linux and Windows binaries from a single source on a network share.
This is a regression introduced in 7525b54f (merged via df5a8a89), GLM_FORCE_DEFAULT_ALIGNED_GENTYPES causes visible screen corruption, particularly in the smoke from chimneys or vehicles.
It causes the game to crash on launch while attempting to use SIMD
instructions when compiled with GCC or Clang.
Since it's known to work on MSVC and was enabled due to performance
improvement, leave it enabled there.
Simplified lamp logic by reducing unnecessary brackets, `if` statements, ternary operators and boolean comparisons.
Added new lamps:
- `i-gear1` - 1st gear in the gearbox is active
- `i-gear2` - 2nd gear in the gearbox is active
- `i-hydrolockup` - The gearbox is locking the engine and wheels together
Additionally, fixed motor overload and differential relay lights not turning off when the battery is turned off.
In TSegment there were two different formulas for a derivative. Most places called GetFirstDerivative() that used the direct formula from the curve points. However RaPositionGet() had its own calculation based on pre-computed cubic polynomial coefficients. This latter method is faster and simpler, so change GetFirstDerivative() to use it and change RaPositionGet() to just call GetFirstDerivative().
TSegment::GetTFromS() is a significant hotspot in the non-rendering part of the state_manager update (about 13%). This change introduces a FastGetTFromS() version that interpolates from precomputed values instead of doing the whole calculation on every call. Computing position from track distance is now done in constant time. This reduces the contribution to about 0.3%.
