This mod implements a simple approach to making the various liquid node types (water, lava) behave in a more realistic manner. In a nutshell, it sets an Active Block Modifier running for liquid nodes that implements the following behavior:
* If there is a "flowing" or air node below a "source" liquid block, swap the liquid block with the node below it (ie, the liquid drops)
* Else swap with a random flowing or air node beside it.
This causes "source" blocks for liquids to randomly shuffle around when they don't completely fill a horizontal layer, and causes them to drain rapidly down holes or flow rapidly down hillsides. Normal "flowing" behaviour is unchanged so even though this mod is just moving cubes around the surface of the water looks reasonably smooth. The ABM only runs for blocks that are adjacent to flowing nodes and does very few calculations so it's also reasonably lightweight - I'm essentially borrowing the engine's built-in liquid flow detection to determine when my own code needs to run.
Each type of liquid can have this behaviour enabled independently of each other. By default lava is configured to flow more slowly than water, but this can be changed in the mod's settings.
## Damp Clay Counters Ocean Loss
If basic water is set as dynamic, it loses its "renewability" - water nodes don't replicate like they normally do. If you are concerned about the global water level dropping over time as water pours down into undersea caverns, or just generally don't like the idea of water being a finite resource (even with an ocean's worth to start with), this mod includes an optional feature that turns natural clay deposits into "springs". Clay deposits get an Active Block Modifier that checks if there's air or shallow water above them and refills them with newly spawned water source blocks.
If this clay is dug out by players and reconstituted into clay blocks elsewhere, the "spring" behaviour won't occur for these - it only happens for clay spawned by mapgen while this feature is enabled. (In technical terms, when clay springs are enabled the map generator replaces generated clay with an otherwise identical "damp clay" node type that drops regular clay when dug. The ABM only affects this "damp clay" node type.)
There's also a "spring" block that's available only via the creative menu or /give command. This block has an ABM that ensures there's always a single block of water generated directly above it, regardless of where the block is placed.
Note that other than this clay spring feature and the override of water's "renewability" this mod doesn't affect any default node definitions, so any other mods dealing with liquids should still function as they did before. If you disable any of the liquid types they will just "freeze" in whatever position they were in at the time.
## "Flow-through" Blocks
There are many blocks in the game that one would think should not serve as an impenetrable barrier to water flow, but which do. For example: metal bars, grass, leaves. The "flow-through" feature of this mod makes them permeable, allowing water_source and lava_source blocks to "teleport" from one side of a flow-through block to the other. Liquid source blocks will only teleport through a single layer of flow-through node and only in the cardinal directions.
Other mods can mark blocks as flow-through by adding them to the "flow_through" group.
## Lava/Water Interaction
Due to the way default lava/water interaction works a single block of lava_source would be able to wander endlessly around on the surface of the ocean turning the uppermost layer of water into stone. Similarly, a single block of water_source could wander around on the surface of a lava pool turning the uppermost layer into obsidian. This is an undesirable outcome so the dynamic_liquid mod includes a more sophisticated replacement to the default lava-cooling ABM.
lava_flowing nodes are now eliminated entirely by nodes marked cools_lava, they do not leave behind default:stone. This means that infinite stone generation is no longer possible using arrangements of lava and water.
lava_source nodes are turned into obsidian only by water_source nodes; water_flowing nodes are eliminated by lava_source nodes without affecting them. The water_source node is destroyed in the process. This means that if you want to cool a large amount of lava you're going to need a correspondingly large amount of water.
For modders, you can now fine-tune the effects of blocks on lava (and vice versa) using the following groups:
* "group:dynamic_cools_lava_flowing" - causes lava_flowing nodes to vanish. The old "group:cools_lava" has this effect.
* "group:dynamic_lava_flowing_destroys" - causes lava_flowing nodes to destroy nodes belonging to this group.
* "group:dynamic_cools_lava_source" - causes lava_source nodes to turn into obsidian. The old "group:cools_lava" does *not* have this effect.
* "group:dynamic_lava_source_destroys" - causes lava_source nodes to destroy nodes belonging to this group.

This mod provides a set of nodes that allow large quantities of water to be pumped from one place to another, potentially over very long distances.
**Important Note:** The default behaviour of water in Minetest does not actually lend itself well to this kind of activity. In particular, ``default:water_source`` has ``liquid_renewable = true`` set in its node definition, which often causes new water nodes to be created where old ones are removed.
This mod includes an optional setting that disables ``liquid_renewable`` for default water, but for best effect it is highly recommended that this mod be used in conjunction with the [dynamic_liquid](https://github.com/minetest-mods/dynamic_liquid) mod.
The [airtanks](https://github.com/minetest-mods/airtanks) mod can also be helpful for players who are interested in doing large-scale underwater construction projects.
A pipe network is only active when a player is near one of the terminal nodes attached to it. The map blocks containing all terminal nodes for the network will be forceloaded as long as the pipe network is active, allowing water to be added or removed from remote locations, but note that water will be unable to flow into or out from those remote map blocks into adjoining blocks so it may behoove a player to visit these places from time to time to ensure continued flow.
## Pipes
The core node type introduced by this mod is the pipe. When pipes are laid adjacent to each other they connect up to form a pipe network, to which inlets, outlets, and pumps can be connected. All contiguous pipes are part of the same network, and all terminal nodes connected to that network will be able to interact with each other through the pipes.
Pipes automatically connect to other pipes through any of their six faces.
## Terminals
Terminals can only be connected to a pipe network via one face, the side that by default is facing away from the player when they place the node in world. They interact with water only on the opposite face - the one facing toward the player when they place the node in world. Terminals require at least one pipe segment to connect to, they don't interact directly with each other.
A screwdriver can be used to reorient terminals if you want one facing upward or downward.
The types of terminals in this mod are:
* Inlets let water enter the pipe but not leave
* Outlets let water out but not in
* Grates let water flow either way depending on pressure
* Pumps are inlets that force water into the network at a higher pressure than their elevation would normally give it.
## Valves
A valve can be used to connect or disconnect sections of a pipe network with a simple right-click. When a valve is "open" it acts like a pipe section, and when it's "closed" it does not act like a pipe.
## Elevation and pressure
The flow of water through the network is determined by two main factors; the directionality of each type of terminal, and the pressure of the water at that terminal.
Water flows from high pressure terminals to low pressure terminals. The rise and fall of the pipe in between those two terminals doesn't really matter, just the pressure at the terminals themselves.
The following figure illustrates the basics of how this works with a very simple three-terminal pipe network:
![Figure 1](/screenshots/waterworks_figure_1.png)
The two terminals on the left side are "inlets", only permitting water to enter the network, and the terminal on the right is a grate that allows water in or out.
If terminal 1 were to be immersed in water, water nodes would be transferred from terminal 1 to terminal 2 because terminal 1's higher elevation gives it higher pressure than terminal 2. Water would *not* be transferred to terminal 3 as terminal 3 is an inlet only.
If terminal 2 were to be immersed, likewise no water would be transferred because although terminal 2 can allow water to enter the pipe (it's a grate) there are no valid outlet terminals it could go to.
If terminal 3 were immersed in water, no water would be transferred because terminal 2 is higher elevation and therefore there isn't enough pressure at terminal 3 to reach it.
![Figure 2](/screenshots/waterworks_figure_2.png)
In this example terminal 3 is a pump, which acts as if it were an inlet located at an elevation 100 meters higher than it actually is. There are two potential outlets for water entering the system. Water is preferentially emitted from the *lowest* pressure outlet, so if terminal 3 was immersed in water it would be sent to terminal 2. However, if terminal 2 was contained in an enclosed space that had run out of room for additional water, the water would then be sent to the next-lowest outlet and come out of terminal 1.
If terminal 1 was immersed, then water would transfer from it to terminal 2. Terminal 3 is an inlet, so water wouldn't come out of it.
