Detailed Description

Class that handles all cargo related functions.

Member Enumeration Documentation

◆ CargoClass

enum GSCargo::CargoClass

The classes of cargo.

Enumerator

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_NON_POURABLE	Non-pourable (open wagon, but not hopper wagon)
CC_POTABLE	Potable / food / clean.
CC_NON_POTABLE	Non-potable / non-food / dirty.

◆ DistributionType

enum GSCargo::DistributionType

Type of cargo distribution.

Enumerator
DT_MANUAL	Manual distribution.
DT_ASYMMETRIC	Asymmetric distribution. Usually cargo will only travel in one direction.
DT_SYMMETRIC	Symmetric distribution. The same amount of cargo travels in each direction between each pair of nodes.
INVALID_DISTRIBUTION_TYPE	Invalid distribution type.

◆ SpecialCargoType

enum GSCargo::SpecialCargoType

Special cargo types.

Enumerator
CT_AUTO_REFIT	Automatically choose cargo type when doing auto-refitting.
CT_NO_REFIT	Do not refit cargo of a vehicle.
CT_INVALID	An invalid cargo type.

◆ TownEffect

enum GSCargo::TownEffect

The effects a cargo can have on a town.

Enumerator
TE_NONE	This cargo has no effect on a town.
TE_PASSENGERS	This cargo supplies passengers to a town.
TE_MAIL	This cargo supplies mail to a town.
TE_GOODS	This cargo supplies goods to a town.
TE_WATER	This cargo supplies water to a town.
TE_FOOD	This cargo supplies food to a town.

Member Function Documentation

◆ GetCargoIncome()

static Money GSCargo::GetCargoIncome	(	CargoType	cargo_type,
		int	distance,
		int	days_in_transit
	)

static

Get the income for transporting a piece of cargo over the given distance within the specified time.

Parameters

cargo_type The cargo to transport.

Precondition: GSCargo::IsValidCargo(cargo_type).

Parameters

distance	The distance the cargo travels from begin to end. The value will be clamped to 0 .. MAX(int).
days_in_transit	Amount of (game) days the cargo is in transit. The max value of this variable is 637. Any value higher returns the same as 637 would.

Returns: The amount of money that would be earned by this trip.

◆ GetCargoLabel()

static string GSCargo::GetCargoLabel ( CargoType cargo_type )

static

Gets the string representation of the cargo label.

Parameters

cargo_type The cargo to get the string representation of.

Precondition: GSCargo::IsValidCargo(cargo_type).

Returns: The cargo label.

Note

The label uniquely identifies a specific cargo. Use this if you want to detect special cargos from specific industry set (like production booster cargos, supplies, ...).
For more generic cargo support, rather check cargo properties though. For example:
- Use GSCargo::HasCargoClass(..., CC_PASSENGER) to decide bus vs. truck requirements.
- Use GSCargo::GetTownEffect(...) paired with GSTown::GetCargoGoal(...) to determine town growth requirements.
In other words: Only use the cargo label, if you know more about the behaviour of a specific cargo from a specific industry set, than the API methods can tell you.

◆ GetDistributionType()

static DistributionType GSCargo::GetDistributionType ( CargoType cargo_type )

static

Get the cargo distribution type for a cargo.

Parameters

cargo_type The cargo to check on.

Returns: The cargo distribution type for the given cargo.

◆ GetName()

static string GSCargo::GetName ( CargoType cargo_type )

static

Get the name of the cargo type.

Parameters

cargo_type The cargo type to get the name of.

Precondition: IsValidCargo(cargo_type).

Returns: The name of the cargo type.

◆ GetTownEffect()

static TownEffect GSCargo::GetTownEffect ( CargoType cargo_type )

static

Get the effect this cargo has on a town.

Parameters

cargo_type The cargo to check on.

Precondition: GSCargo::IsValidCargo(cargo_type).

Returns: The effect this cargo has on a town, or TE_NONE if it has no effect.

◆ GetWeight()

static int GSCargo::GetWeight	(	CargoType	cargo_type,
		int	amount
	)

static

Get the weight in tonnes for the given amount of cargo for the specified type.

Parameters

cargo_type	The cargo to check on.
amount	The quantity of cargo. The value will be clamped to 0 .. MAX(int).

Precondition: GSCargo::IsValidCargo(cargo_type).

Returns: The weight in tonnes for that quantity of cargo.

◆ HasCargoClass()

static bool GSCargo::HasCargoClass	(	CargoType	cargo_type,
		CargoClass	cargo_class
	)

static

Check if this cargo is in the requested cargo class.

Parameters

cargo_type The cargo to check on.

Precondition: GSCargo::IsValidCargo(cargo_type).

Parameters

cargo_class The class to check for.

Returns: True if and only if the cargo is in the cargo class.

◆ IsFreight()

static bool GSCargo::IsFreight ( CargoType cargo_type )

static

Checks whether the give cargo is a freight or not.

This defines whether the "freight train weight multiplier" will apply to trains transporting this cargo.

Parameters

cargo_type The cargo to check on.

Precondition: GSCargo::IsValidCargo(cargo_type).

Returns: True if and only if the cargo is freight.

◆ IsValidCargo()

static bool GSCargo::IsValidCargo ( CargoType cargo_type )

static

Checks whether the given cargo type is valid.

Parameters

cargo_type The cargo to check.

Returns: True if and only if the cargo type is valid.

◆ IsValidTownEffect()

static bool GSCargo::IsValidTownEffect ( TownEffect towneffect_type )

static

Checks whether the given town effect type is valid.

Parameters

towneffect_type The town effect to check.

Returns: True if and only if the town effect type is valid.
