◆ BuildCargoAcceptanceString()

std::optional< std::string > BuildCargoAcceptanceString	(	const CargoArray &	acceptance,
		StringID	label
	)

Build comma-separated cargo acceptance string.

Parameters

acceptance	CargoArray filled with accepted cargo.
label	Label to prefix cargo acceptance list.

Returns: String of accepted cargo, or nullopt if no cargo is accepted.

◆ BuildCargoLabelMap()

void BuildCargoLabelMap ( )

Build cargo label map.

This is called multiple times during NewGRF initialization as cargos are defined, so that TranslateRefitMask() and GetCargoTranslation(), also used during initialization, get the correct information.

◆ CargoSpecClassSorter()

static bool CargoSpecClassSorter	(	const CargoSpec *const &	a,
		const CargoSpec *const &	b
	)

static

Sort cargo specifications by their cargo class.

◆ CargoSpecNameSorter()

static bool CargoSpecNameSorter	(	const CargoSpec *const &	a,

◆ GetClimateDependentCargoTranslationTable()

std::span< const CargoLabel > GetClimateDependentCargoTranslationTable ( )

Get default climate-dependent cargo translation table for a NewGRF, used if the NewGRF does not provide its own.

Returns: Default translation table for GRF version.

Returns: Default translation table for GRF version.

◆ IsDefaultCargo()

bool IsDefaultCargo ( CargoType cargo_type )

Test if a cargo is a default cargo type.

Parameters

cargo_type Cargo type.

Returns: true iff the cargo type is a default cargo type.

◆ SetupCargoForClimate()

void SetupCargoForClimate ( LandscapeType l )

Parameters

Variable Documentation

◆ _cargo_mask

CargoTypes _cargo_mask

Bitmask of cargo types available.

This includes phony cargoes like regearing cargoes. Initialized during a call to SetupCargoForClimate.

◆ _climate_dependent_cargo_labels

std::array<CargoLabel, 12> _climate_dependent_cargo_labels

static

Default cargo translation for up to version 7 NewGRFs.

This maps the original 12 cargo slots to their original label. If a climate dependent cargo is not present it will map to CT_INVALID. For default cargoes this ends up as a 1:1 mapping via climate slot -> label -> cargo type.

Definition at line 49 of file cargotype.cpp.

Referenced by GetClimateDependentCargoTranslationTable().

◆ _climate_independent_cargo_labels

std::array<CargoLabel, 32> _climate_independent_cargo_labels

static

Default cargo translation for version 8+ NewGRFs.

This maps the 32 "bitnum" cargo slots to their original label. If a bitnum is not present it will map to CT_INVALID.

Referenced by GetClimateIndependentCargoTranslationTable().

◆ _default_cargo_labels

std::vector<CargoLabel> _default_cargo_labels

static

List of default cargo labels, used when setting up cargo types for default vehicles.

This is done by label so that a cargo label can be redefined in a different slot.
