Member Function Documentation

GetDebugID()

uint32_t HouseResolverObject::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 124 of file newgrf_house.cpp.

References HouseSpec::Get(), HouseSpec::grf_prop, HouseScopeResolver::house_id, and GRFFilePropsBase< Tcnt >::local_id.

GetFeature()

GrfSpecFeature HouseResolverObject::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 119 of file newgrf_house.cpp.

GetScope()

ScopeResolver * HouseResolverObject::GetScope ( VarSpriteGroupScope  scope = VSG_SCOPE_SELF, uint8_t  relative = 0  )

inlineoverridevirtual

Get a resolver for the scope.

Returns

The resolver for the requested scope.

Reimplemented from ResolverObject.
