bedrockdb {rbedrock}R Documentation

Open a Bedrock Edition world for reading and writing.

Description

bedrockdb opens a handle to a leveldb database that contains save-game data for a Bedrock Edition world. On success, it returns an R6 class of type 'bedrockdb' that can be used directly for low-level reading and writing access to the db or can be passed to higher-level functions. The handle to the database can be closed by passing it to close.
