=== BUILTIN_ITEM MOD for MINETEST-C55 ===
|
||||
by PilzAdam
|
||||
|
||||
Features:
|
||||
This mod adds some new features to the builtin items:
|
||||
- The items are pushed by flowing water
|
||||
- The items are destroyed by lava
|
||||
- The items are removed after 300 seconds or the time that is specified by
|
||||
remove_items in minetest.conf (0 disables it)
|
||||
|
||||
How to install:
|
||||
Unzip the archive an place it in minetest-base-directory/mods/minetest/
|
||||
if you have a windows client or a linux run-in-place client. If you have
|
||||
a linux system-wide instalation place it in ~/.minetest/mods/minetest/.
|
||||
If you want to install this mod only in one world create the folder
|
||||
worldmods/ in your worlddirectory.
