Caelus API — Minecraft mod
by TheIllusiveC4
Caelus abstracts Minecraft's hardcoded elytra behaviour into a generic fall-flying attribute, letting mod authors enable gliding from their own items without touching the elytra itself. The attribute defaults to zero, which forbids flight, while any value of one or above allows it; the vanilla elytra now uses the same attribute and plays exactly as before. Purely a dependency, with nothing added for players on its own.
