Public Member Functions

void ResetToDefaultMapping ()
 Initializes the EngineOverrideManager with the default engines.
EngineID GetID (VehicleType type, uint16 grf_local_id, uint32 grfid)
 Looks up an EngineID in the EngineOverrideManager.

Static Public Attributes

static const uint NUM_DEFAULT_ENGINES = _engine_counts[VEH_TRAIN] + _engine_counts[VEH_ROAD] + _engine_counts[VEH_SHIP] + _engine_counts[VEH_AIRCRAFT]
 Number of default entries.

Detailed Description

Stores the mapping of EngineID to the internal id of newgrfs.

Note: This is not part of Engine, as the data in the EngineOverrideManager and the engine pool get resetted in different cases.

Member Function Documentation

EngineID EngineOverrideManager::GetID ( VehicleType  type,
uint16  grf_local_id,
uint32  grfid 
)

Looks up an EngineID in the EngineOverrideManager.

Parameters:
type Vehicle type
grf_local_id The local id in the newgrf
grfid The GrfID that defines the scope of grf_local_id. If a newgrf overrides the engines of another newgrf, the "scope grfid" is the ID of the overridden newgrf. If dynnamic_engines is disabled, all newgrf share the same ID scope identified by INVALID_GRFID.
Returns:
The engine ID if present, or INVALID_ENGINE if not.
