Functions | |
void | ConnectMultiheadedTrains () |
Link front and rear multiheaded engines to each other This is done when loading a savegame. | |
void | ConvertOldMultiheadToNew () |
Converts all trains to the new subtype format introduced in savegame 16.2 It also links multiheaded engines or make them forget they are multiheaded if no suitable partner is found. | |
void | UpdateOldAircraft () |
need to be called to load aircraft from old version | |
static void | CheckValidVehicles () |
Check all vehicles to ensure their engine type is valid for the currently loaded NewGRFs (that includes none...) This only makes a difference if NewGRFs are missing, otherwise all vehicles will be valid. More... | |
void | AfterLoadVehicles (bool part_of_load) |
Called after load to update coordinates. More... | |
bool | TrainController (Train *v, Vehicle *nomove, bool reverse=true) |
Move a vehicle chain one movement stop forwards. More... | |
void | ReverseTrainDirection (Train *v) |
Turn a train around. More... | |
void | ReverseTrainSwapVeh (Train *v, int l, int r) |
Swap vehicles l and r in consist v, and reverse their direction. More... | |
void | FixupTrainLengths () |
Fixup old train spacing. More... | |
const SaveLoad * | GetVehicleDescription (VehicleType vt) |
Make it possible to make the saveload tables "friends" of other classes. More... | |
static void | Save_VEHS () |
Will be called when the vehicles need to be saved. More... | |
void | Load_VEHS () |
Will be called when vehicles need to be loaded. More... | |
static void | Ptrs_VEHS () |
Variables | |
byte | _age_cargo_skip_counter |
Skip aging of cargo? Used before savegame version 162. | |

const ChunkHandler | _veh_chunk_handlers [] |
Code handling saving and loading of vehicles.
Definition in file vehicle_sl.cpp.
void AfterLoadVehicles | ( | bool | part_of_load | ) |
Called after load to update coordinates.
So we can set the #previous and #first pointers while loading.
For instantiating the shared vehicle chain.

Check all vehicles to ensure their engine type is valid for the currently loaded NewGRFs (that includes none...) This only makes a difference if NewGRFs are missing, otherwise all vehicles will be valid.
This does not make such a game playable, it only prevents crash.

void FixupTrainLengths | ( | ) |
Fixup old train spacing.

const SaveLoad* GetVehicleDescription | ( | VehicleType | vt | ) |
Make it possible to make the saveload tables "friends" of other classes.
So we can use private/protected variables in the saveload code.
Saving and loading the current order of vehicles.
The vehicles have a cargo list (and we want that saved).
vt | the vehicle type. Can be VEH_END for the common vehicle description data |
Save and load of vehicles

void Load_VEHS | ( | ) |
Will be called when vehicles need to be loaded.
Loading of ancient vehicles.

void ReverseTrainDirection | ( | Train * | v | ) |
Turn a train around.
v | Train to turn around. |

void ReverseTrainSwapVeh | ( | Train * | v, |
int | l, | ||
int | r | ||
) |
Swap vehicles l and r in consist v, and reverse their direction.
v | Consist to change. |
l | Vehicle index in the consist of the first vehicle. |
r | Vehicle index in the consist of the second vehicle. |

static |
Will be called when the vehicles need to be saved.

References FOR_ALL_VEHICLES.
Move a vehicle chain one movement stop forwards.
v | First vehicle to move. |
nomove | Stop moving this and all following vehicles. |
reverse | Set to false to not execute the vehicle reversing. This does not change any other logic. |
