Mod to completely cut trees by destroying only one block.
|
|
This mod allows to destroy the bottom of the tree and the whole tree is felled
|
|
and moved to the players inventory.
|
|
|
|
To distinguish between "grown" trees and placed tree nodes, the attribute
|
|
'node.param1' is used to identify placed nodes.
|
|
|
|
The number of necessary lumberjack points has to be configured via 'settingtypes.txt'
