Description
Vines grow naturally on tree trunks and stone walls in jungle, swamp, mangrove swamp, and lush cave biomes. Each vine block occupies one full block face and can be climbed like a ladder as long as a solid block sits directly behind it.
Spread happens one block at a time: an existing vine can extend horizontally to adjacent wall faces or grow a new block downward, eventually reaching the ground. Bone meal accelerates spreading. With shears, vines drop as a collectible item; without shears they vanish. They can be placed manually on any solid block face in all six directions.
A vine block on a ceiling is climbable only when a solid block is directly above the player's position. Because they spread unchecked, containing vines in a controlled build requires periodic pruning or enclosing them behind walled sections. Pistons can push vines, making automated trim farms possible with simple BUD-switch circuits.
