About this project
What does Lazy Blocks add?
Lazy Blocks
Lazy Blocks adds five automation blocks that handle tree farming, fish collecting, crop harvesting and flower and grass collecting so you don't have to.
🌳 Tree Cutter
Place a sapling, add bone meal and an axe — the Tree Cutter chops the tree automatically, depositing logs, leaves, and apples into its output slots.

🌾 Crop Harvester
Place a seed or crop, add bone meal and a hoe — the Crop Harvester handles the rest. Supports all vanilla crops, and if you're playing with Farmer's Delight or Vinery, those crops work too. Watch out for the occasional poisonous potato or rotten tomato! 🥔🍅

🐟 Fish Collector
Place a main input ( kelp, seagrass, sea pickle or lily pad), add bone meal and an fishing rod — the Fish Collector collect fish, junk and treasure for you automatically, depositing items into its output slots. Fish collector use real vanilla fishing loot by default ( with upgrades is just better for treasure😉).

🌼 Botanical Harvester
Automatically harvests flowers and other plants that can be grown using Bone Meal and harvested by hand. Requires Bone Meal and a Stick to operate.

✂️ Trimming Machine
Automatically trims plants that can be grown using Bone Meal and harvested with Shears. Requires Bone Meal and Shears to operate. Produces items such as Ferns, Vines, and other plant drops.

| Durability I / II / III | Less tool durability per cycle (default is 4, every upgrade is 1 less) |
