PerformGRM()

uint32_t PerformGRM ( std::span< GrfID > grm, uint16_t count, uint8_t op, uint8_t target, std::string_view type )

static

Performs the GRF Resource Management, where NewGRFs can cooperatively manage sprite resources.

Parameters

grm	Mapping to the NewGRF linked with a resource.
count	The number of elements to process.
op	The operation to perform.
target	The target for the operation.
type	Name of type for debug messages.

Returns

Operation/target specific result.

Variable Documentation

_grm_cargoes

std::array<GrfID, NUM_CARGO * 2> _grm_cargoes {}

static

Contains the GRF ID of the owner of a cargo if it has been reserved.

_grm_engines

std::array<GrfID, 256> _grm_engines {}

static

Contains the GRF ID of the owner of a vehicle if it has been reserved.

GRM for vehicles is only used if dynamic engine allocation is disabled, so 256 is the number of original engines.
