Ocean API

Ocean API is a Forge library for Minecraft 1.12.2 that adds ocean biomes, per-biome water colors and entity buckets. It also swaps the vanilla water textures for new grayscale textures that are tinted at runtime, so the tint can change with the biome a player is in. Because the new water textures are registered as sprites that replace the vanilla ones, mods that reference the old textures keep working. Client and server both need the mod, so installation has to happen on the server and on every player's client.

The water coloring can be tuned through a configuration file. A config setting is disabled by default and turns on the modern water textures. Those textures are taken from newer Minecraft versions, and the config setting requires AssetMover and Aqua Acrobatics to be installed, since they provide the way Ocean API grabs the modern water textures. Aqua Acrobatics also gets full support for its biome water colors, which register automatically once they are enabled. Support also exists for water fluids from Simple Difficulty and Underdog.

The project page includes screenshots taken with the Faithful 32x and Tropical Waters packs, which change how water looks once the new textures are applied.
