Constructor & Destructor Documentation

RailTypeResolverObject()

RailTypeResolverObject::RailTypeResolverObject	(	const RailTypeInfo *	rti,
		TileIndex	tile,
		TileContext	context,
		RailTypeSpriteGroup	rtsg,
		uint32_t	param1 = 0,
		uint32_t	param2 = 0
	)

Resolver object for rail types.

Parameters

rti	Railtype. nullptr in NewGRF Inspect window.
tile	Tile containing the track. For track on a bridge this is the southern bridgehead.
context	Are we resolving sprites for the upper halftile, or on a bridge?
rtsg	Railpart of interest
param1	Extra parameter (first parameter of the callback, except railtypes do not have callbacks).
param2	Extra parameter (second parameter of the callback, except railtypes do not have callbacks).

Member Function Documentation

GetDebugID()

uint32_t 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 67 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 62 of file newgrf_railtype.cpp.

GetScope()

ScopeResolver * RailTypeResolverObject::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.

Definition at line 44 of file newgrf_railtype.h.

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

Referenced by NIHRailType::Resolve().

Field Documentation

railtype_scope

RailTypeScopeResolver RailTypeResolverObject::railtype_scope

Resolver for the railtype scope.
