Change item handling: Import VoxBox code
VoxBox' item_drop code is much more stable and the item drop behaviour seems to be much more “natural”. But it is incompatible with builtin_item, so this mod must be disabled. Merging the builtin_item features is planned.

Introduction:
|
||||
This mod adds Minecraft like drop/pick up of items to Minetest.
|
||||
|
||||
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.
|
||||
For further information or help see:
|
||||
http://wiki.minetest.com/wiki/Installing_Mods
|
||||
|
||||
How to use the mod:
|
||||
Just install it an everything works.
|
||||
|
||||
For developers:
|
||||
You dont have to use get_drops() anymore because of changes in the
|
||||
builtin files of minetest.
|
||||
This mod has been forked from item_drop in the VoxBox subgame.
