Member Function Documentation

EngineID EngineOverrideManager::GetID	(	VehicleType	type,
		uint16_t	grf_local_id,
		uint32_t	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.
