-- Version 3.0
|
|
|
|
-- Changelog:
|
|
-- 02.09.2021 * Added a history of stored patterns (not saved over server restart)
|
|
-- * Added a menu to select a history entry. It is accessable via AUX1 + left click.
|
|
-- * Removed deprecated functions get/set_metadata(..) and renamed metadata to pattern
|
|
-- 29.09.2021 * AUX1 key works now same as SNEAK key for storing new pattern (=easier when flying)
|
|
-- * The description of the tool now shows which pattern is stored
|
|
-- * The description of the stored pattern is more human readable
|
|
-- 09.12.2017 * Got rid of outdated minetest.env
|
|
-- * Fixed error in protection function.
|
|
-- * Fixed minor bugs.
|
|
-- * Added blacklist
|
|
-- 02.10.2014 * Some more improvements for inspect-tool. Added craft-guide.
|
|
-- 01.10.2014 * Added inspect-tool.
|
|
-- 12.01.2013 * If digging the node was unsuccessful, then the replacement will now fail
|
|
-- (instead of destroying the old node with its metadata; i.e. chests with content)
|
|
-- 20.11.2013 * if the server version is new enough, minetest.is_protected is used
|
|
-- in order to check if the replacement is allowed
|
|
-- 24.04.2013 * param1 and param2 are now stored
|
|
-- * hold sneak + right click to store new pattern
|
|
-- * right click: place one of the itmes
|
|
-- * receipe changed
|
|
-- * inventory image added
|
|
|
|
-- adds a function to check ownership of a node; taken from VanessaEs homedecor mod
