◆ CheckConsistencyOfArticulatedVehicle()

void CheckConsistencyOfArticulatedVehicle ( const Vehicle * v)

Checks whether the specs of freshly build articulated vehicles are consistent with the information specified in the purchase list.

Only essential information is checked to leave room for magic tricks/workarounds to grfcoders. It checks: For autoreplace/-renew:

  • Default cargo type (without capacity)
  • intersection and union of refit masks.

◆ CountArticulatedParts()

uint CountArticulatedParts ( EngineID engine_type)

Count the number of articulated parts of an engine.

Parameters
engine_typeThe engine to get the number of parts of.
Returns
The number of parts.

◆ GetArticulatedRefitMasks()

void GetArticulatedRefitMasks ( EngineID engine,
bool include_initial_cargo_type,
CargoTypes * union_mask,
CargoTypes * intersection_mask )

Merges the refit_masks of all articulated parts.

Parameters
enginethe first part
include_initial_cargo_typeif true the default cargo type of the vehicle is included; if false only the refit_mask
union_maskreturns bit mask of CargoTypes which are a refit option for at least one articulated part
intersection_maskreturns bit mask of CargoTypes which are a refit option for every articulated part (with default capacity > 0)

CargoType * cargo_type )

Get cargo mask of all cargoes carried by an articulated vehicle.

Note: Vehicles not carrying anything are ignored

Parameters
