Function Documentation

static Track ChooseShipTrack ( Vehicle *  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 CmdRefitShip ( TileIndex  tile,
DoCommandFlag  flags,

Refits a ship to the specified cargo type.

Parameters:
tile unused
flags type of operation
p1 vehicle ID of the ship to refit
p2 various bitstuffed elements
  • p2 = (bit 0-7) - the new cargo type to refit to (p2 & 0xFF)
  • p2 = (bit 8-15) - the new cargo subtype to refit to
  • p2 = (bit 16) - refit only this vehicle (ignored)
Returns:
cost of refit or error
