Function Documentation

GetAirportTileIDAtOffset()

static uint32_t GetAirportTileIDAtOffset ( TileIndex  tile, const Station *  st, uint32_t  cur_grfid  )

static

Make an analysis of a tile and check whether it belongs to the same airport, and/or the same grf file.

Parameters

tile	TileIndex of the tile to query
st	Station to which to compare the tile to
cur_grfid	GRFID of the current callback

Returns

value encoded as per NFO specs

GetNearbyAirportTileInformation()

static uint32_t GetNearbyAirportTileInformation ( uint8_t  parameter, TileIndex  tile, StationID  index, bool  grf_version8  )

static

Based on newhouses/newindustries equivalent, but adapted for airports.

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
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

GetTranslatedAirportTileID()

StationGfx GetTranslatedAirportTileID

(

StationGfx

gfx

)

Do airporttile gfx ID translation for NewGRFs.

Parameters

gfx	the type to get the override for.

Returns

the gfx to actually work with.
