Making an automated farm in CraftBook involves three different "integrated circuits":
To create an integrated ciruit, place a block down and then on that block, place a sign. The second line of the sign should be the name of the IC in square brackets, like so:
The "s" at the end is optional, but it makes the IC run its own without a constant Redstone signal clock and is necessary for our farms.
Many ICs require extra parameters which are specified on the third and fourth line. For the relevant ICs we will need here, those extra parameters will be explained below.
Some ICs, like the planter and harvester, need a chest. You can place the chest on top of the block behind the sign, as you will see later.
MC1234 is the planter.
A planter setup to place saplings around it is shown below.
You can also see that a chest has been placed above the block.
MC1239 is the harvester.
Below is an example harvester for a tree farm.
MC1214 is the item collector, and you only need it if you're harvesting saplings because they drop saplings when trees are cut down.
Below is an example item collector for a tree farm.
A simple but inefficient tree farm is pictured below, where all three ICs (planter, harvester, item collector) are placed on the same block. This design is inefficient because it takes up space where trees could be growing, plus the storage chest is only a single chest.
