◆ DoReseedIndustry()

static void DoReseedIndustry	(	Industry *	ind,
		uint32_t	reseed
	)

static

Reseeds the random bits of an industry.

Parameters

ind	Industry.
reseed	Bits to reseed.

◆ DoTriggerIndustryTile()

static void DoTriggerIndustryTile	(	TileIndex	tile,
		IndustryTileTrigger	trigger,
		Industry *	ind,
		uint32_t &	reseed_industry
	)

static

Trigger random triggers for an industry tile and reseed its random bits.

◆ GetIndTileGrffile()

static const GRFFile* GetIndTileGrffile ( IndustryGfx gfx )

static

Get the associated NewGRF file from the industry graphics.

Parameters

gfx	Graphics to query.

Returns: Grf file associated with the graphics, if any.

◆ GetNearbyIndustryTileInformation()

uint32_t GetNearbyIndustryTileInformation	(	uint8_t	parameter,
		TileIndex	tile,
		IndustryID	index,
		bool	signed_offsets,
		bool	grf_version8
	)

Based on newhouses equivalent, but adapted for newindustries.

Parameters

parameter	from callback. It's in fact a pair of coordinates
tile	TileIndex from which the callback was initiated
index	of the industry been queried for
signed_offsets	Are the x and y offset encoded in parameter signed?
grf_version8	True, if we are dealing with a new NewGRF which uses GRF version >= 8.

Returns: a construction of bits obeying the newgrf format

◆ GetRelativePosition()

uint32_t GetRelativePosition	(	TileIndex	tile,
		TileIndex	ind_tile
	)

This is the position of the tile relative to the northernmost tile of the industry.

Format: 00yxYYXX Variable Content x the x offset from the northernmost tile XX same, but stored in a byte instead of a nibble y the y offset from the northernmost tile YY same, but stored in a byte instead of a nibble

Parameters

tile	TileIndex of the tile to evaluate
ind_tile	northernmost tile of the industry

		IndustryType	type,
		IndustryGfx	gfx,
		size_t	layout_index,
		uint16_t	initial_random_bits,
		Owner	founder,
		IndustryAvailabilityCallType	creation_type
	)

Check the slope of a tile of a new industry.

Parameters

ind_base_tile	Base tile of the industry.
ind_tile	Tile to check.
its	Tile specification.
type	Industry type.
gfx	Gfx of the tile.
layout_index	Layout.
initial_random_bits	Random bits of industry after construction
founder	Industry founder
creation_type	The circumstances the industry is created under.

Returns: Succeeded or failed command.

void TriggerIndustry	(	Industry *	ind,
		IndustryTileTrigger	trigger
	)

Trigger a random trigger for all industry tiles.

Parameters

ind	Industry to trigger.
trigger	Trigger to trigger.
