=== SPEARS for MINETEST by Echoes91 ===

|

This mod adds spears to Minetest. It aims at improving the ones introduced within throwing enhanced.
|
||||
This mod adds spears to Minetest.
|
||||
|
||||
How to install:
|
||||
http://wiki.minetest.com/wiki/Installing_Mods
|
||||
|
||||
How to use the mod:
|
||||
Spear work similarly to other tools such as swords, even if being a little slower. Moreover, a spear can be thrown using the drop key ('Q') or placed on a node using the place key ('right click'); they have also limited digging capabilities.
|
||||
Craft a spear with | stick | stick | (material) |, also mirrored.
|
||||
Spears can be thrown using right mouse button, they either hurt someone or stick where they land on. Damage depends on speed and material, flight trajectory is ballistic with drag.
|
||||
Spears can be used to fight, but are slower and weaker than swords.
|
||||
Spears can be used to dig, but are slower and weaker and pickaxes.
