void DeleteVehicleOrders | ( | Vehicle * | v,
|  | bool | keep_orderlist |
| ) |  |  |

Delete all orders from a vehicle.

Date GetServiceIntervalClamped | ( | uint | index | ) |

Get the service interval domain.

Get the new proposed service interval for the vehicle is indeed, clamped within the given bounds.

See also:
  MIN_SERVINT_PERCENT ,etc.

Parameters:

  | index | proposed service interval

Returns:
  service interval

void InvalidateVehicleOrder | ( | const Vehicle * | v,
|  | int | data |
| ) |  |  |

Updates the widgets of a vehicle which contains the order-data.

VehicleOrderID ProcessConditionalOrder | ( | const Order * | order,
|  | const Vehicle * | v |
| ) |  |  |

Process a conditional order and determine the next order.

Parameters:

  | order | the order the vehicle currently has
  | v | the vehicle to update

Returns:
  index of next order to jump to, or INVALID_VEH_ORDER_ID to use the next order

bool ProcessOrders | ( | Vehicle * | v | ) |

Handle the orders of a vehicle and determine the next place to go to if needed.

Parameters:

  | v | the vehicle to do this for.

Returns:
  true *if* the vehicle is eligible for reversing (basically only when leaving a station).

Reversing because of order change is allowed only just after leaving a station (and the difficulty setting to allowed, of course) this can be detected because only after OT_LEAVESTATION, current_order will be reset to nothing. (That also happens if no order, but in that case it won't hit the point in code where may_reverse is checked)

void RemoveOrderFromAllVehicles | ( | OrderType | type,
|  | DestinationID | destination |
| ) |  |  |

Removes an order from all vehicles.

Triggers when, say, a station is removed.

Parameters:

  | type | The type of the order (OT_GOTO_[STATION|DEPOT|WAYPOINT]).
  | destination | The destination. Can be a StationID, DepotID or WaypointID.

void RestoreVehicleOrders | ( | const Vehicle * | v,
|  | const BackuppedOrders * | bak |
