Living Reefs

First public release, for Minecraft 26.3 on Fabric.

Added

• Living coral gets random ticks: thriving coral spreads its own species into nearby still water, as plants and fans on reef substrate, wall fans on the side of a block, and coral blocks up to a height cap.
• Reef health from real conditions: warm ocean water (biome tag: coral spreads only there or near an active conduit, and stays as it is elsewhere), light (sky or block, so sea pickles and lanterns light deep reefs), heat sources, frozen water, nearby coral density and open water above.
• Bleaching: coral next to magma or lava, or in frozen water, turns into its dead twin.
• Recovery: thriving coral slowly revives wet dead coral of its own species next to it, unless a heat source would bleach it again. Dry dead coral, such as decoration on land, is never touched.
• Boosts from tropical fish, sea pickles and an active conduit; a conduit also makes any water a reef and shelters coral from bleaching.
• /livingreefs (alias /reef): check [pos] explains a coral's health and how many open spots it can spread to (a typed position must be within 16 blocks unless you are an admin), stats shows counts and the handler's own time, reload re-reads config/livingreefs.json.
• Game rules livingreefs:coral_growth and livingreefs:coral_bleaching; block and biome tags livingreefs:reef_substrate, reef_heat_sources, reef_waters and frozen_waters.
• Permission nodes through fabric-permissions-api (bundled), with vanilla level fallback.
• Server-side: vanilla clients can join.
