## Define Documentation

#define FOR_ALL_CARGOSPECS_FROM | ( | var,
|  | start |  | ) |

Value:

    for (size_t cargospec_index = start; var = NULL, cargospec_index < CargoSpec::GetArraySize(); cargospec_index++) \
        if ((var = CargoSpec::Get(cargospec_index))->IsValid())

Definition at line 144 of file cargotype.h.

## Typedef Documentation

typedef uint32 CargoLabel

Globally unique label of a cargo type.

Definition at line 22 of file cargotype.h.

## Enumeration Type Documentation

enum CargoClass

Cargo classes.

Enumerator:

  CC_NOAVAILABLE | No cargo class has been specified.
  CC_PASSENGERS | Passengers.
  CC_MAIL | Mail.
  CC_EXPRESS | Express cargo (Goods, Food, Candy, but also possible for passengers).
  CC_ARMOURED | Armoured cargo (Valuables, Gold, Diamonds).
  CC_BULK | Bulk cargo (Coal, Grain etc., Ores, Fruit).
  CC_PIECE_GOODS | Piece goods (Livestock, Wood, Steel, Paper).
  CC_LIQUID | Liquids (Oil, Water, Rubber).
  CC_REFRIGERATED | Refrigerated cargo (Food, Fruit).
  CC_HAZARDOUS | Hazardous cargo (Nuclear Fuel, Explosives, etc.).
  CC_COVERED | Covered/Sheltered Freight (Transporation in Box Vans, Silo Wagons, etc.).
  CC_SPECIAL | Special bit used for livery refit tricks instead of normal cargoes.

Definition at line 35 of file cargotype.h.

enum TownEffect

Town growth effect when delivering cargo.

Enumerator:

  TE_NONE | Cargo has no effect.
  TE_PASSENGERS | Cargo behaves passenger-like.
  TE_MAIL | Cargo behaves mail-like.
  TE_GOODS | Cargo behaves goods/candy-like.
  TE_WATER | Cargo behaves water-like.
  TE_FOOD | Cargo behaves food/fizzy-drinks-like.

## Function Documentation

CargoID GetCargoIDByBitnum | ( | uint8 | bitnum | ) |

Find the CargoID of a 'bitnum' value.

Parameters:

  | bitnum | 'bitnum' to find.

Returns:
  First CargoID with the given bitnum, or CT_INVALID if not found or if the provided bitnum is invalid.

Definition at line 87 of file cargotype.cpp.

References CargoSpec::bitnum, CT_INVALID, CargoSpec::Index(), and INVALID_CARGO.

CargoID GetCargoIDByLabel | ( | CargoLabel | cl | ) |

Get the cargo ID by cargo label.

Parameters:

  | cl | Cargo type to get.

Returns:
  ID number if the cargo exists, else CT_INVALID

Definition at line 71 of file cargotype.cpp.

static bool IsCargoInClass | ( | CargoID | c,
|  | CargoClass | cc |
| ) |  |  | `[inline, static]`

Does cargo c have cargo class cc?

Parameters:

  | c | Cargo type.
  | cc | Cargo class.

Returns:
  The type fits in the class.
