Function Documentation

int AllocateSpecToStation ( const StationSpec *  statspec,
Station *  st,
bool  exec 
)

Allocate a StationSpec to a Station.

This is called once per build operation.

Parameters:
statspec StationSpec to allocate.
st Station to allocate it to.
exec Whether to actually allocate the spec.
Returns:
Index within the Station's spec list, or -1 if the allocation failed.

StationClassID AllocateStationClass ( uint32  cls  ) 

Allocate a station class for the given class id.

Parameters:
cls A 32 bit value identifying the class.
Returns:
Index into _station_classes of allocated class.

void DeallocateSpecFromStation ( Station *  st,
byte  specindex 
)

Deallocate a StationSpec from a Station.

Called when removing a single station tile.

Parameters:
st Station to work with.
specindex Index of the custom station within the Station's spec list.
Returns:
Indicates whether the StationSpec was deallocated.

bool DrawStationTile ( int  x,
int  y,
RailType  railtype,
Axis  axis,
StationClassID  sclass,
uint  station 
)

Draw representation of a station tile for GUI purposes.

Parameters:
x Position x of image.
y Position y of image.
axis Axis.
railtype Rail type.
sclass,station Type of station.
station station ID
Returns:
True if the tile was drawn (allows for fallback to default graphic)
