-- Here is a handy Lua command line script for listing all nodes that are owned
|
||
|
|
-- by specific players (like steel doors, locked chests, etc.) in your map
|
||
|
|
-- database. Just change the following variables at the head of the script:
|
||
|
|
--
|
||
|
|
-- * path - the path of the map.sqlite database to be read
|
||
|
|
-- * area - the region of the map to be searched, specified as minimum and
|
||
|
|
-- maximum mapblock positions
|
||
|
|
-- * owner_name- the name of the owner to search for (nil will search for all
|
||
|
|
-- owners)
|
||
|
|
-- * node_name- the name of the owned nodes to search for (nil will search for
|
||
|
|
-- all owned nodes)
|
||
|
|
--
|
||
|
|
-- Keep in mind, this script can take some time to process very large databases,
|
||
|
|
-- so it is strongly recommended to limit the search area to no more than ~50
|
||
|
|
-- cubic mapblocks at a time.
