Static build of leveldb-mcpe-legacy for 64-bit Windows.
Run build.cmd to compile locally. Ensure that you have the required
dependencies installed. See beginning of build.cmd for more information.
leveldb-mcpe is a fork of Google's leveldb with added support for zlib. This fork is used for the world storage format for minecraft bedrock edition.
Other compression formats are present in this fork. However due to their lack of use in bedrock edition they are excluded from this build.
This fork of leveldb is only intended to be used for interacting with minecraft worlds generated from bedrock edition.
Using leveldb-mcpe is very similar to using leveldb. The main difference is
that you must set the compression option to leveldb_zlib_raw_compression
when opening a database in order to read data from bedrock worlds.
The following is a basic example of how to use the C based api exposed by leveldb-mcpe:
#include <leveldb\c.h>
#include <stdio.h>
int main()
{
// Supply your path here.
const char* DatabaseDir = "";
// Basic database types.
leveldb_t* Database;
leveldb_options_t* Options;
// Required for error checking on all database operations.
char* Status = NULL;
// Create config for our database.
Options = leveldb_options_create();
leveldb_options_set_create_if_missing(Options, 1);
// Needed to read bedrock world data.
leveldb_options_set_compression(Options, leveldb_zlib_raw_compression);
// Open world.
Database = leveldb_open(Options, DatabaseDir, &Status);
// We need these to read and write to the database.
leveldb_readoptions_t* ReadOptions = leveldb_readoptions_create();
leveldb_writeoptions_t* WriteOptions = leveldb_writeoptions_create();
// Uncomment to use synchronous writes.
//leveldb_writeoptions_set_sync(WriteOptions, 1);
// Create iterator to loop through the entire database.
leveldb_iterator_t* Iter = leveldb_create_iterator(Database, ReadOptions);
for (leveldb_iter_seek_to_first(Iter); leveldb_iter_valid(Iter); leveldb_iter_next(Iter))
{
size_t KeyLength, ValueLength;
const char* Key = leveldb_iter_key(Iter, &KeyLength);
const char* Value = leveldb_iter_value(Iter, &ValueLength);
printf("Key length: %zu, Value Length %zu\n", KeyLength, ValueLength);
}
// Destory the iterator.
// This must be done before closing a database, otherwise an assertion is thrown.
leveldb_iter_destroy(Iter);
// Close the database.
leveldb_close(Database);
return 0;
