◆ CheckIfCallBackAllowsCreation()

CommandCost CheckIfCallBackAllowsCreation	(	TileIndex	tile,
		IndustryType	type,
		size_t	layout,
		uint32_t	seed,
		uint16_t	initial_random_bits,
		Owner	founder,
		IndustryAvailabilityCallType	creation_type
	)

Check that the industry callback allows creation of the industry.

Parameters

tile	Tile to build the industry.
type	Type of industry to build.
layout	Layout number.
seed	Seed for the random generator.
initial_random_bits	The random bits the industry is going to have after construction.
founder	Industry founder
creation_type	The circumstances the industry is created under.

Returns: Succeeded or failed command.

Definition at line 534 of file newgrf_industries.cpp.

◆ GetCountAndDistanceOfClosestInstance()

static uint32_t GetCountAndDistanceOfClosestInstance	(	uint8_t	param_setID,
		uint8_t	layout_filter,
		bool	town_filter,
		const Industry *	current
	)

static

Implementation of both var 67 and 68 since the mechanism is almost the same, it is easier to regroup them on the same function.

Parameters

param_setID	parameter given to the callback, which is the set id, or the local id, in our terminology
layout_filter	on what layout do we filter?
town_filter	Do we filter on the same town as the current industry?
current	Industry for which the inquiry is made

Returns: the formatted answer to the callback : rr(reserved) cc(count) dddd(manhattan distance of closest sister)

< Get the GRFID of the definition to look for in register 100h

◆ GetGrffile()

static const GRFFile* GetGrffile ( IndustryType type )

static

Get the grf file associated with the given industry type.

Parameters

type	Industry type to query.

Returns: The associated GRF file, if any.

Definition at line 452 of file newgrf_industries.cpp.

References GetIndustrySpec(), IndustrySpec::grf_prop, and GRFFilePropsBase< Tcnt >::grffile.

◆ GetIndustryCallback()

uint16_t GetIndustryCallback	(	CallbackID	callback,
		uint32_t	param1,
		uint32_t	param2,
		Industry *	industry,
		IndustryType	type,
		TileIndex	tile
	)

Perform an industry callback.

Parameters

callback	The callback to perform.
param1	The first parameter.
param2	The second parameter.
industry	The industry to do the callback for.
type	The type of industry to do the callback for.
tile	The tile associated with the callback.

Returns: The callback result.

Definition at line 517 of file newgrf_industries.cpp.

◆ GetIndustryIDAtOffset()

uint32_t GetIndustryIDAtOffset	(	TileIndex	tile,
		const Industry *	i,
		uint32_t	cur_grfid
	)

Make an analysis of a tile and check for its belonging to the same industry, and/or the same grf file.

Parameters

tile	TileIndex of the tile to query
i	Industry to which to compare the tile to
cur_grfid	GRFID of the current callback chain

Returns: value encoded as per NFO specs

◆ GetIndustryProbabilityCallback()

uint32_t GetIndustryProbabilityCallback	(	IndustryType	type,
		IndustryAvailabilityCallType	creation_type,
		uint32_t	default_prob
	)

Check with callback CBID_INDUSTRY_PROBABILITY whether the industry can be built.

Parameters

type	Industry type to check.
creation_type	Reason to construct a new industry.

Returns: If the industry has no callback or allows building, true is returned. Otherwise, false is returned.

◆ IndustryProductionCallback()

void IndustryProductionCallback	(	Industry *	ind,
		int	reason
	)

Get the industry production callback and apply it to the industry.

Parameters

ind	the industry this callback has to be called for
reason	the reason it is called (0 = incoming cargo, 1 = periodic tick callback)

◆ IndustryTemporarilyRefusesCargo()

bool IndustryTemporarilyRefusesCargo	(	Industry *	ind,
		CargoID	cargo_type
	)

Check whether an industry temporarily refuses to accept a certain cargo.

Parameters

ind	The industry to query.
cargo_type	The cargo to get information about.

Precondition: cargo_type is in ind->accepts_cargo.

Returns: Whether the given industry refuses to accept this cargo type.

◆ MapNewGRFIndustryType()

IndustryType MapNewGRFIndustryType	(	IndustryType	grf_type,
		uint32_t	grf_id
	)

Map the GRF local type to an industry type.

Parameters

grf_type	The GRF local type.
grf_id	The GRF of the local type.

Returns: The industry type in the global scope.
