Member Function Documentation

const AirportFTAClass* Airport::GetFTA (  )  const [inline]

Get the finite-state machine for this airport or the finite-state machine for the dummy airport in case this isn't an airport.

Precondition:
this->type < NEW_AIRPORT_OFFSET.
Returns:
The state machine for this airport.

FORCEINLINE uint Airport::GetHangarNum ( TileIndex  tile  )  const [inline]

Get the hangar number of the hangar on a specific tile.

Parameters:
tile The tile to query.
Precondition:
IsHangarTile(tile).
Returns:
The hangar number of the hangar at the given tile.

Definition at line 136 of file station_base.h.

FORCEINLINE TileIndex Airport::GetHangarTile ( uint  hangar_num  )  const [inline]

Get the first tile of the given hangar.

Parameters:
hangar_num The hangar to get the location of.
Precondition:
hangar_num < GetNumHangars().
Returns:
A tile with the given hangar.

FORCEINLINE uint Airport::GetNumHangars (  )  const [inline]

Get the number of hangars on this airport.

Referenced by AIDepotList::AIDepotList(), AIAirport::GetNumHangars(), and RemoveAirport().

FORCEINLINE TileIndex Airport::GetRotatedTileFromOffset ( TileIndexDiffC  tidc  )  const [inline]

Add the tileoffset to the base tile of this airport but rotate it first.

The base tile is the northernmost tile of this airport. This function helps to make sure that getting the tile of a hangar works even for rotated airport layouts without requiring a rotated array of hangar tiles.

Parameters:
tidc The tilediff to add to the airport tile.
Returns:
The tile of this airport plus the rotated offset.

const AirportSpec* Airport::GetSpec (  )  const [inline]

Get the AirportSpec that from the airport type of this airport.

If there is no airport (tile == INVALID_TILE) then return the dummy AirportSpec.

Returns:
The AirportSpec for this airport.

Check if this airport has at least one hangar.
