Hybrid API [HAPI]
by Hybrid Labs
Hybrid API is a library that Hybrid Labs mods share, providing the base code, tags and standards that let addons be built on top of them.
What it does
The library contains the shared base code that other Hybrid Labs projects rely on. It provides biome, item, entity and other tags, which make it easier for mods built on it to stay compatible with each other. Developers can use it to create addons that add their own sea creatures, birds and watercraft at the same level as the main projects.
Hybrid API requires Fabric API, Fabric Language Kotlin and Geckolib on Fabric, and Kotlin for Forge on Forge and NeoForge. Five mods in the catalog depend on it: Hybrid Aquatic, Hybrid Birds, Hybrid Delights, Fish 'N' Ships and Fantastic Fishery. The library is published for Fabric, Forge and NeoForge across the 1.20.1 and 1.21.1 game versions, and it is open source under the MIT License.
