This mod adds in
MOAR PETS TO MINECRAFT!!! :D a new block called the "Redstone Detector". Basically, it identifies block updates that happen next to it, and sends out a redstone signal if there is one. (Block updates are stuff like blocks being placed, broken, or changed.)
- "Buddy" is an obvious pun of "Block Update Detector".
- In the vanilla, a B.U.D. Switch is a redstone device using pistons that is used to... well, detect block updates. This mod just condenses that into a single block.
