Walkthrough

The change updates ramp and passenger vertical-position calculations for stacked-deck vehicles. It also changes helicopter landing and vehicle falling or floating checks to account for the lowest occupied positions in vehicle columns.

Changes: Stacked-deck vehicle behavior

Layer / File(s)	Summary
Stacked-deck ramp offsets `src/vehicle.cpp`, `src/map.cpp`	Ramp calculations now account for stacked decks, part destinations, and whether the vehicle is flying. Passenger placement derives its vertical offset from the part’s deck height and destination ramp.
Column-based landing and support checks `src/vehicle_move.cpp`	Helicopter landing checks examine the lowest part in each occupied column. For stacked-deck vehicles, support and falling or floating checks use the lowest occupied position in each column.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

BreezeDevTeam/CDDA-Breeze#1251: Both changes affect part z-coordinate handling for stacked-deck vehicles on ramps.

Merge Risk: Moderate · previous review ee5f0

The change fixes layer collapse on bridges, but it can still place a turning stacked-deck vehicle at the wrong z-level. Passengers on flying vehicles can end up one level off from their part. Vehicles leaving a ramp can stay suspended with one deck column raised. These should be fixed before merge.

retaining cur.z for the current-height calculation; update the rc construction
accordingly.
- Line 1612: Guard the passenger ramp adjustment branches that update
psg_offset_z for TFLAG_RAMP_UP and TFLAG_RAMP_DOWN with veh.is_flying_in_air(),
so neither ramp offset is applied while the vehicle is flying.

- Line 2097: Update the support handling in level_vehicle() to check the lowest
structural part in each stacked-deck column and lower only columns whose lowest
part lacks support. Preserve the existing per-column offsets from

Keep support checks for stacked-deck columns.

A stacked-deck vehicle can retain unequal column offsets after leaving a ramp. In advance_precalc_mounts(), col_ramp starts from prt.precalc[1].z - prt.mount_z; when the destination has no ramp, the code does not reset it. It subtracts only the common ramp_offset, so a raised lower-deck column can remain above unsupported terrain.

level_vehicle() now skips the support checks that previously detected unsupported Z-levels and called displace_vehicle(). check_falling_or_floating() is not a replacement: it stops after any lowest column has support. Check the lowest structural part in each column and lower unsupported columns without restoring the old whole-level collapse behavior.
