Detailed Description

Functions for NewGRF industries.

Definition in file newgrf_industries.h.

Enumeration Type Documentation

◆ IndustryAvailabilityCallType

enum IndustryAvailabilityCallType

From where has callback CBID_INDUSTRY_PROBABILITY been called.

Enumerator
IACT_MAPGENERATION	during random map generation
IACT_RANDOMCREATION	during creation of random ingame industry
IACT_USERCREATION	from the Fund/build window
IACT_PROSPECTCREATION	from the Fund/build using prospecting

Definition at line 81 of file newgrf_industries.h.

◆ IndustryTrigger

enum IndustryTrigger

When should the industry(tile) be triggered for random bits?

Enumerator
INDUSTRY_TRIGGER_TILELOOP_PROCESS	Triggered each tile loop.
INDUSTRY_TRIGGER_256_TICKS	Triggered (whole industry) each 256 ticks.
INDUSTRY_TRIGGER_CARGO_DELIVERY	Triggered on cargo delivery.

Definition at line 71 of file newgrf_industries.h.

Function Documentation

◆ 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.

		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.

◆ 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.
