Constructor & Destructor Documentation

◆ RailTypeResolverObject()

RailTypeResolverObject::RailTypeResolverObject ( const RailtypeInfo rti,
TileIndex  tile,
TileContext  context,
RailTypeSpriteGroup  rtsg,
uint32  param1 = 0,
uint32  param2 = 0 
)

Resolver object for rail types.

Parameters
rtiRailtype. nullptr in NewGRF Inspect window.
tileTile containing the track. For track on a bridge this is the southern bridgehead.
contextAre we resolving sprites for the upper halftile, or on a bridge?
rtsgRailpart of interest
param1Extra parameter (first parameter of the callback, except railtypes do not have callbacks).
param2Extra parameter (second parameter of the callback, except railtypes do not have callbacks).

Member Function Documentation

◆ GetDebugID()

uint32 RailTypeResolverObject::GetDebugID ( ) const
overridevirtual

Get an identifier for the item being resolved.

This function is mainly intended for the callback profiling feature, and should return an identifier recognisable by the NewGRF developer.

Reimplemented from ResolverObject.

Definition at line 66 of file newgrf_railtype.cpp.

References RailtypeInfo::label, and railtype_scope.

◆ GetFeature()

GrfSpecFeature RailTypeResolverObject::GetFeature ( ) const
overridevirtual

Get the feature number being resolved for.

This function is mainly intended for the callback profiling feature.

Reimplemented from ResolverObject.

Definition at line 61 of file newgrf_railtype.cpp.

◆ GetScope()

ScopeResolver* RailTypeResolverObject::GetScope ( VarSpriteGroupScope  scope = VSG_SCOPE_SELF,
byte  relative = 0 
)
inlineoverridevirtual

Get a resolver for the scope.

Parameters
scopeScope to return.
relativeAdditional parameter for VSG_SCOPE_RELATIVE.
Returns
The resolver for the requested scope.

Reimplemented from ResolverObject.

Definition at line 44 of file newgrf_railtype.h.

References ResolverObject::GetScope(), railtype_scope, and VSG_SCOPE_SELF.
