Closes the JSON round-trip gap on the vehicle catalog format
shipped last batch. --export-wvhc-json emits all 10 scalar
fields plus a nested array of seats per entry, and dual int +
name forms for vehicleKind / movementKind / powerType so
hand-edits can use either representation. --import-wvhc-json
accepts either form, falling back to the int when both are
present, and reconstructs the seat array preserving seat
flags / attachments / control-spell cross-refs. Verified
byte-identical round-trip on all three preset emitters
(starter / siege / flying), including nested seat data. 702
documented CLI flags.
43rd open format — replaces Vehicle.dbc + VehicleSeat.dbc plus
the AzerothCore-style vehicle_template SQL tables. Defines
drivable vehicles: tanks, demolishers, motorcycles, gryphons,
choppers, siege weapons, multi-passenger transports. Each entry
pairs a creature template (the rendered model) with a fixed
seat layout — driver / passenger / gunner seats with their own
attachment points, control flags (kSeatDriver / kSeatGunner /
kSeatPassenger / kSeatHidesPlayer / kSeatNoEjectByCC), and
per-seat abilities mounted to the action bar.
Cross-references with prior formats — creatureId points at
WCRT.creatureId (the rendered model), flightCapabilityId points
at WMNT.mountId for shared fly-speed tables, and per-seat
controlSpellId / exitSpellId point at WSPL.spellId.
CLI: --gen-vehicles (3-vehicle starter chopper/wind-rider/tank),
--gen-vehicles-siege (3 siege weapons with control spellIds),
--gen-vehicles-flying (3 flying mounts cross-ref WMNT
flightCapabilityIds), --info-wvhc, --validate-wvhc with --json
variants. Validator catches id=0/duplicates, missing creature,
enum out-of-range, empty seat list, flying-vehicle on wrong
movement (would fall through world), driver-flag exclusivity
(0 or >1 drivers), and duplicate seatIndex within a vehicle.
