=== TNT-MOD for MINETEST-C55 ===
by PilzAdam
=== TNT mod for Minetest ===
by PilzAdam and ShadowNinja
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
surround gunpowder with 4 wood in a + shape.
There are different ways to blow up TNT:
1. Hit it with a torch.
2. Hit a gunpowder fuze that leads to a TNT block with a torch.
3. Activate it with mesecons (fastest way)
1. Hit it with a torch.
2. Hit a gunpowder fuze that leads to a TNT block with a torch.
3. Activate it with mesecons (fastest way)
Be aware of the damage radius of 7 blocks!
