LavaRecycle

LavaRecycle is a lightweight Minecraft 1.21+ Paper plugin that adds useful quality-of-life mechanics for lava and cauldrons.

Features

Lava Recycling with Bone Meal

• Right-click on a lava source block or lava cauldron with bone meal to recycle it.
• 80% chance: Only sound + happy villager particles (no change).
• 20% chance: Lava is converted into a random solid block:
  • Common (85% of successful rolls): Stone, Deepslate, Tuff, Diorite, Granite, Andesite, Basalt, Blackstone.
  • Rare (~15% of successful rolls): Ores including Coal, Copper, Iron, Gold, Redstone, Lapis, Emerald, and Diamond (with their deepslate variants).

Dispenser support: You can also dispense bone meal directly at lava/lava cauldrons to trigger the same effect.

Enhanced Cauldron Dispenser Support

Dispensers can now fully interact with cauldrons:

• Fill empty cauldrons using Water Bucket, Lava Bucket, Powder Snow Bucket, and all mob buckets (Axolotl, Cod, Salmon, Tadpole, Tropical Fish, Pufferfish).
• Empty filled cauldrons back into empty buckets.

Commands

Permissions
