Detailed Description

Interface to query and set values specific to a single VarSpriteGroupScope (action 2 scope).

Multiple of these interfaces are combined into a ResolverObject to allow access to different game entities from a SpriteGroup-chain (action 1-2-3 chain).

Member Function Documentation

◆ GetRandomBits()

uint32_t ScopeResolver::GetRandomBits ( ) const

virtual

Get a few random bits.

Default implementation has no random bits.

Returns: Random bits.

Reimplemented in StationScopeResolver, RoadTypeScopeResolver, RoadStopScopeResolver, RailTypeScopeResolver, ObjectScopeResolver, IndustryTileScopeResolver, IndustriesScopeResolver, HouseScopeResolver, VehicleScopeResolver, CanalScopeResolver, AirportTileScopeResolver, and AirportScopeResolver.

Definition at line 85 of file newgrf_spritegroup.cpp.

◆ GetTriggers()

uint32_t ScopeResolver::GetTriggers ( ) const

virtual

Get the triggers.

Base class returns 0 to prevent trouble.

Returns: The triggers.

Reimplemented in StationScopeResolver, RoadStopScopeResolver, IndustryTileScopeResolver, IndustriesScopeResolver, HouseScopeResolver, and VehicleScopeResolver.

Definition at line 94 of file newgrf_spritegroup.cpp.

◆ GetVariable()

uint32_t ScopeResolver::GetVariable	(	uint8_t	variable,
		[[maybe_unused] ] uint32_t	parameter,
		bool &	available
	)		const

virtual

Get a variable value.

Default implementation has no available variables.

Parameters

	variable	Variable to read
	parameter	Parameter for 60+x variables
[out]	available	Set to false, in case the variable does not exist.

Returns: Value

Reimplemented in TownScopeResolver, StationScopeResolver, RoadTypeScopeResolver, RoadStopScopeResolver, RailTypeScopeResolver, ObjectScopeResolver, IndustryTileScopeResolver, IndustriesScopeResolver, HouseScopeResolver, GenericScopeResolver, VehicleScopeResolver, CanalScopeResolver, AirportTileScopeResolver, and AirportScopeResolver.

◆ StorePSA()

void ScopeResolver::StorePSA	(	uint	reg,
		int32_t	value
	)

virtual

Store a value into the persistent storage area (PSA).

Default implementation does nothing (for newgrf classes without storage).

Reimplemented in TownScopeResolver, IndustriesScopeResolver, and AirportScopeResolver.
