# Lumberjack
|
||||||
|
|
||||||
|
A simple mod based on ideas from the mods TreeCapitator, Timber, and New Timber.
|
||||||
|
This mod allows to hit the bottom of the tree and the whole tree (wood) is harvested
|
||||||
|
and moved to the players inventory.
|
||||||
|
To distinguish between "grown" trees and playes tree nodes, the 'node.param1'
|
||||||
|
is used to identify placed nodes.
