Function Documentation

static Track ChooseShipTrack ( Ship v,
TileIndex  tile,
DiagDirection  enterdir,
TrackBits  tracks 
) [static]

returns the track to choose on the next tile, or -1 when it's better to reverse.

The tile given is the tile we are about to enter, enterdir is the direction in which we are entering the tile

CommandCost CmdBuildShip ( TileIndex  tile,
DoCommandFlag  flags,
const Engine e,
uint16  data,
Vehicle **  ret 
)

Build a ship.

Parameters:
tile tile of the depot where ship is built.
flags type of operation.
e the engine to build.
data unused.
ret[out] the vehicle that has been built.
Returns:
the cost of this operation or an error.
