Flowing Fluids

About

Flowing fluids is a mod adding more realistic fluid physics to the game, making fluids mostly finite, and adding an element of fluid management to the game. With dozens of settings for performance, flowing behaviour, gameplay elements, and visuals

It is a spiritual successor to some of the various other abandoned water physics mods over the years, but built from scratch for modern Minecraft.

Implemented in a way that is compatible with (most) mod added fluids, and that allows you to disable/remove the mod at any time to return to vanilla mechanics with any 'not currently flowing' fluids remaining fully intact for vanilla purposes.

Server side or Client side?

This mod works best when on both server and client side. However, it is only required on the server side, if you don't want the visual features and don't mind some minor client-side de-sync when directly interacting with fluids, such as using buckets.

There is no harm in joining a vanilla server with this mod enabled, however you will get the same minor client-side de-sync as you would when joining a server with the mod without it on the client.

⚠ The mod is currently in early development ⚠

It is not yet feature complete, and I make no promises of stability at this stage, as there may yet be some unknown breaking bugs and further room for performance improvements.

Features

Many of these can be tweaked or even disabled via the /flowing_fluids settings command, use /flowing_fluids help if you are confused.

Flowing Fluids

Fluids will flow and spread outwards and down inclines, filling up spaces and creating pools.

This can be tweaked in various ways, such as how far they flow, and how aggressively the fluid tries to level itself in pools.

This means you can create things like aqueducts.

or flood areas with water.

or lava.

or even modded fluids.

Finite Fluids

Fluids are finite, and will flow until they run out, or are blocked.

This means you will need to manage your water supply, and can't just place 2 water source blocks and have infinite water.

Oceans, Rivers, and Swamps however, will act as infinite water sources, but there is a limit to how fast they will refill, and they can still be drained if fast enough (controlled in settings).

These biomes will also absorb any non-full water that flows back into it at sea level, also adjustable via settings.

Fluids will also be displaced by blocks wherever possible to avoid losing any fluid.

Piston Pumps

Fluids can be moved by pistons to pump them upwards automatically.

Gameplay Elements

There are a few new gameplay elements that will drain or use water, to encourage water management, most are configurable.

Such as farmlands having a chance to drain a water level whenever it hydrates.

Animals having a chance to require and consume 1 level of nearby water (within 8 blocks) when breeding.

Bottles will consume 2-3 water levels when filled.

Buckets are able to pick up 1 - 8 levels of fluid, and can be used to place down precise amounts.

With fluids being displaced by block placement, you will need to find other ways to drain it away, such as using sponges, creating drains, or tweaking the evaporation settings mentioned below.

There are also various ways in which water specifically naturally evaporates or refills (Rates customizable via settings)

• Small (level 1) water puddles will evaporate slowly in the over world.
• Any water will evaporate quickly in the nether.
• Any water blocks that are not full (levels 1-7) will refill over time when exposed to rain.
• Any water blocks that are not full (levels 1-7) will refill over time when in Ocean, River, or Swamp biomes, below sea level, and exposed to skylight.'

Mod and Vanilla backwards compatibility

Any mod added fluids should work with the mod, though if the modded fluid has special properties, they may not be fully supported.

You can also blacklist modded fluids that you don't want to have physics. Via the /flowing_fluids settings ignored_fluids add <fluid_name> command.
