◆ 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
parameterfrom callback. It's in fact a pair of coordinates
tileTileIndex from which the callback was initiated
indexof the industry been queried for
signed_offsetsAre the x and y offset encoded in parameter signed?
grf_version8True, 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
tileTileIndex of the tile to evaluate
ind_tilenorthernmost tile of the industry
