fix(cab): the line contactors lamp goes out with the pressure switch (eu07/maszyna#470)
The lamp of the open line contactors, which tells the start can be made, went out at 1 bar in the brake
cylinders, while the pressure switch cuts the start off only at 2 bar (or below 3.6 bar in the main pipe), so
with the brakes partly applied the start could be made with the lamp out. With a pressure switch fitted the lamp
now follows it; without one it goes out at 1 bar as before. The same holds for the lamp of the second unit, which
used to keep its last state between 1 bar and the cut-off. The condition is
TMoverParameters::LineContactorsLampLit().
Tests: tests/unit/test_line_contactors.cpp.
refactor: Sonar findings of PR 217
- horn_supply::pneumatic shadowed the pneumatic enumerator of the sound flags (cpp:S1117), it's horn_supply::air;
the supplies read with using enum (S6177),
- CouplerForce(): the automatic coupling refused or caught without another level of nested ifs (S134), the
same outcome: too fast, the coupling is locked; caught, coupled and locked; otherwise left to try again,
- CompressorCheck(): the power the compressor doesn't draw yet noted without a TODO (S1135),
- tests: the previous crash damage setting in an in-class initializer (S3230), the loops which stop early with
break rather than in their conditions (S886), the stand-ins of test::pair in a std::vector rather than an array
(S5945), units in the comments of the example without /* */ (S1103).
test: the cases the changes of the branch left without a test
- Cntrl.: BDelay1 to BDelay4 reach the brake delays (now through std::format), the default start types of the
ground and converter overload relays of a multiple unit and of other vehicles (out of the nested conditionals),
- the compressor: fed from the low voltage it waits from the low voltage coming on; the pressure switch stops it
above the cut-out pressure, without one the excess air is vented (the vented fraction rewritten),
- the horns: a vehicle without any air sounds as before, the threshold pressure, an electric horn on 110 V,
- the positions of a cab control below zero, and a control without position sounds.
refactor(cab): the kind of the train heating switch as a flag
Read once with the vehicle definition, rather than compared as text in each of the switch commands.
feat(cab): train heating switch springing back (MaSzyna-EU07/maszyna#85)
TrainHeating=[toggle]|impulse in the Switches: section of the vehicle definition makes the train heating switch
an unstable one: it goes up to switch the heating on, down to switch it off, and back to the middle once let go,
instead of staying where it was put. The position of such a switch isn't set from the heating state when the cab
is entered.
Tests: tests/unit/test_switches.cpp.
feat(sound): mirror sounds (MaSzyna-EU07/maszyna#84, eu07/maszyna#322)
The sound definitions of a vehicle (.mmd) take mirroropen: and mirrorclose:, played as a mirror sets off
unfolding or folding, and the locations section mirrors: <offset>... end, the offsets along the vehicle of the
mirror pairs, as for the doors (negative ahead of the centre), each pair at the sides of the vehicle. As the
animation, only the mirrors at the occupied cab sound. The start of a move is mirror_moves::motion in
vehicle/mirrors.h.
Tests: tests/unit/test_mirrors.cpp.
feat(cab): joint oil and fuel pump switch (MaSzyna-EU07/maszyna#81)
A cab control oilfuelpump_sw: switches both the oil and the fuel pump at once, with the new command
oilfuelpumptoggle (no key by default). As a two-state switch it turns both pumps off when both are on and both on
otherwise; as an impulse switch it's held to start them, like the separate pump switches. Its position follows
the pumps when the cab is entered.
refactor(editor): text fields filled without strncpy (MaSzyna-EU07/maszyna#112)
The last three strncpy calls Sonar flags (cpp:S5816), in the road and track editors, copy the text into the
ImGui field buffers with std::string::copy and terminate it right after; the text gets cut to the buffer as
before.
fix: automatic coupler crashes, horns, compressor start delay, radio and cab lever sounds
- automatic couplers don't catch above the safe collision speed (#86): with crash damage on they couple at a
closing speed of 15 km/h at most, a faster hit locks the coupling until the vehicles part and the collision
runs its course. On the way: CollisionVelocity() read a head-on 10 + 10 km/h as 14.1 km/h (quaternions turn
by half the angle), it's now taken from the touching ends; CollisionDetect() took the other vehicle's speed
the wrong way round for vehicles facing each other. Head-on hits now derail sooner, at the intended limit,
- a single horn lever can't sound both tones at once (eu07/maszyna#392),
- a skid ends once the vehicle stops on locked wheels (eu07/maszyna#479),
- electronic destination signs are blanked at the end of the timetable (eu07/maszyna#446),
- horns need the air or the voltage to sound (eu07/maszyna#290, #76): HornType=[Pneumatic]|Electric and
Horn3Type in Cntrl.; a pneumatic horn needs 0.2 MPa in the main reservoir (or the main pipe without one),
an electric one the low voltage; the lever stays where it was put,
- compressor start delay (#67): CompressorStartDelay [s] in Brake., counted from the compressor getting its
power, after the engine starts say; none by default,
- the channel and volume buttons of a radio without power do nothing (eu07/maszyna#429); the power check of
the radio is TMoverParameters::RadioPowered(),
- a lever moved smoothly sounds the positions it passes (#83).
Sonar findings in the functions changed: nesting, nested conditionals, commented-out code, std::format,
references to const. Unit tests: test::pair for two vehicles running into each other, test_couplers,
test_horn, test_wheelslip, test_compressor, test_radio, test_gauge_positions.
The dumb3d->glm / utilities-simplification refactor replaced the old custom
clamp() (which tolerated Lo>Hi, returning the upper bound) with std::clamp,
where inverted bounds are undefined behaviour. Only a few sites were patched
afterwards, by hand, with std::minmax plumbing (incl. a stray `static` inside
a per-axle loop). Others silently produced wrong results in the AI braking /
acceleration path.
Add a safe_clamp() helper (normalizes inverted bounds) and use it ONLY where
Lo<=Hi cannot be proven at compile time (config min/max pairs, sign-dependent
expressions, container underflow). Sites with constant bounds or [0, x>=0]
keep std::clamp. Remove the manual std::minmax workarounds and rewrite the
damaged-track jolt code value-first.
- The `TMoverParameters::derail()` function has been renamed to `::Derail()`, with a capital D.
- All derail events now use that function.
- Simplified and unified the logic behind different derail types.
- The `dtrack_freerail` track type is now slightly increasing the chance of derailing on a tight curve, as it was the intention.
- A new `DerailReason` enum has been created which holds all derail types.
- The `DerailReason` field in the `TMoverParameters` class has been removed.
- This was a transient field which is not necessary anymore.
- The logging functionality as such has been moved from `DynObj.cpp` to `Mover.cpp`.
