	need to be called to load aircraft from old version

Detailed Description

Code handling saving and loading of vehicles.

Definition in file vehicle_sl.cpp.

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 256 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

v	Train 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

v	Consist to change.
l	Vehicle index in the consist of the first vehicle.
r	Vehicle index in the consist of the second vehicle.

Definition at line 1630 of file train_cmd.cpp.

References SpecializedVehicle< T, Type >::Next().

TrainController()

bool TrainController	(	Train *	v,
		Vehicle *	nomove,
		bool	reverse
	)

Move a vehicle chain one movement stop forwards.

Parameters

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.

Returns

True if the vehicle could be moved forward, false otherwise.
