Introduction:
|
||||
This mod adds TNT to Minetest. TNT is a tool to help the player
|
||||
in mining.
|
||||
|
||||
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:
|
||||
Craft gunpowder by placing coal and gravel in the crafting area. The
|
||||
gunpowder can be used to craft TNT or as fuze for TNT. To craft TNT
