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...

Function Documentation

◆ AfterLoadVehiclesPhase1()

void AfterLoadVehiclesPhase1 ( bool  part_of_load)

Called after load for phase 1 of vehicle initialisation.

So we can set the #previous and #first pointers while loading.

For instantiating the shared vehicle chain.

Definition at line 255 of file vehicle_sl.cpp.

◆ CheckValidVehicles()

static void CheckValidVehicles ( )
static

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.

◆ ReverseTrainDirection()

void ReverseTrainDirection ( Train v)

Turn a train around.

Parameters
vTrain to turn around.

References IsRailDepotTile(), and Vehicle::tile.

◆ ReverseTrainSwapVeh()

void ReverseTrainSwapVeh ( Train v,
int  l,
int  r 
)

Swap vehicles l and r in consist v, and reverse their direction.

Parameters
vConsist to change.
lVehicle index in the consist of the first vehicle.
rVehicle index in the consist of the second vehicle.
