void DrawWaypointSprite | ( | int | x,
|  | int | y,
|  | int | stat_id,
|  | RailType | railtype |
| ) |  |  |

Parameters:

  | x | coordinate
  | y | coordinate
  | stat_id | station id
  | railtype | RailType to use for

Axis GetAxisForNewWaypoint | ( | TileIndex | tile | ) |

Get the axis for a new waypoint.

This means that if it is a valid tile to build a waypoint on it returns a valid Axis, otherwise an invalid one.

Parameters:

  | tile | the tile to look at.

Returns:
  the axis for the to-be-build waypoint.

CommandCost RemoveBuoy | ( | TileIndex | tile,
|  | DoCommandFlag | flags |
| ) |  |  |

Remove a buoy.

Parameters:

  | tile | TileIndex been queried
  | flags | operation to perform

Precondition:
  IsBuoyTile(tile)

Returns:
  cost or failure of operation
