Checksums {rbedrock}

Load and store Checksums data

Description

Checksums data (tag 59) holds checksums for several chunk records. These records are 2DMaps (tag 45), SubchunkBlocks (tag 47), BlockEntities (tag 49), and Entities (tag 50).

get_checksums_data() loads Checksums data from a bedrockdb. It will silently drop and keys not representing Checksums data. get_checksums_values() is a synonym for get_checksums_data().

get_checksums_value() loads Checksums data from a bedrockdb. It only supports loading a single value.

update_checksums_data() recalculates Checksums data. It calculates checksums for the specified chunks' SubchunkBlocks, 2DMaps, BlockEntities, and Entities records in db and updates the Checksums record to match.

read_checksums_value() parses a binary Checksums record into a list of checksums.

write_checksums_value() converts Checksums from a named list into binary format.

Usage

get_checksums_data(db, x, z, dimension)

get_checksums_values(db, x, z, dimension)

get_checksums_value(db, x, z, dimension)

update_checksums_data(db, x, z, dimension)

read_checksums_value(rawdata)

write_checksums_value(object)

Arguments

db

A bedrockdb object.

x, z, dimension

Chunk coordinates to extract data from. x can also be a character vector of db keys.

rawdata

a raw vector holding binary Checksums data

object

a named character vector in the same format as returned by read_checksums_value().

Value

get_checksums_data() returns a named-list of the values returned by get_checksums_value().

get_checksums_value() and read_checksums_value() return a character vector. The names of the character vector indicate which chunk record (tag and subtag) the checksum is for.

write_checksums_value() returns a raw vector.
