harvester.lua
|
|
|
|
Harvester machine to chop wood, leaves and harvest farming crops and flowers.
|
|
|
|
The machine is able to harvest an square area of up to 33x33 blocks (radius = 16).
|
|
The base node has to be placed in the middle of the harvesting area.
|
|
The Harvester processes one node every 6 seconds.
|
|
It requires one item Bio Fuel per 20 nodes.
