## Detailed Description

All ships have this type.

Definition at line 23 of file ship.h.

## Constructor & Destructor Documentation

virtual Ship::~Ship | ( |  | ) | `[inline, virtual]`

We want to 'destruct' the right class.

## Member Function Documentation

bool Ship::FindClosestDepot | ( | TileIndex * | location,
|  | DestinationID * | destination,
|  | bool * | reverse |
| ) |  |  | `[virtual]`

Find the closest depot for this vehicle and tell us the location, DestinationID and whether we should reverse.

Parameters:

  | location | where do we go to?
  | destination | what hangar do we go to?
  | reverse | should the vehicle be reversed?

Returns:
  true if a depot could be found.

int Ship::GetDisplayMaxSpeed | ( |  | ) | const`[inline, virtual]`

Gets the maximum speed in km-ish/h that can be sent into SetDParam for string processing.

Returns:
  the vehicle's maximum speed

Returns:
  the vehicle's speed

ExpensesType Ship::GetExpenseType | ( | bool | income | ) | const`[inline, virtual]`

SpriteID Ship::GetImage | ( | Direction | direction | ) | const`[virtual]`

Gets the sprite to show for the given direction.

Parameters:

  | direction | the direction the vehicle is facing

Returns:
  the sprite for the given vehicle in the given direction

TileIndex Ship::GetOrderStationLocation | ( | StationID | station | ) | `[virtual]`

Determine the location for the station where the vehicle goes to next.

Things done for example are allocating slots in a road stop or exact location of the platform is determined for ships.

Parameters:

  | station | the station to make the next location of the vehicle.

Returns:
  the location (tile) to aim for.

Returns:

const char* Ship::GetTypeString | ( |  | ) | const`[inline, virtual]`

Get a string 'representation' of the vehicle type.

Returns:
  the string representation.

Reimplemented from Vehicle.

Definition at line 31 of file ship.h.

Trackdir Ship::GetVehicleTrackdir | ( |  | ) | const`[virtual]`

Returns the Trackdir on which the vehicle is currently located.

Works for trains and ships. Currently works only sortof for road vehicles, since they have a fuzzy concept of being "on" a trackdir. Dunno really what it returns for a road vehicle that is halfway a tile, never really understood that part. For road vehicles that are at the beginning or end of the tile, should just return the diagonal trackdir on which they are driving. I _think_. For other vehicles types, or vehicles with no clear trackdir (such as those in depots), returns 0xFF.

Returns:
  the trackdir of the vehicle

void Ship::MarkDirty | ( |  | ) | `[virtual]`
