'''Liquids''' are special dynamic [[block]]s in Minetest. They behave quite differently than in real life. Liquids like to spread and flow to their surrounding blocks and players can swim and drown in them.

== Liquid forms ==
Liquids usually come in two forms: In source form and in flowing form.

=== Liquid source ===
Liquid sources have the shape of a full cube. A liquid source will generate flowing liquids around it from time to time, and, if the liquid is renewable, it also generates liquid sources (see below). A liquid source can sustain itself. If no special event happens, a liquid source will keep its place forever and it will never drain out.

=== Flowing liquid ===
Flowing liquids take a “sloped” form and never the shape of a cube. Flowing liquids spread around the map until they drain. A flowing liquid can not sustain itself and always comes from a liquid source, either directly or indirectly. Without a liquid source, a flowing liquid will eventually drain out and disappear.

== Liquid properties ==
[[Image:Liquid_range_2.png|thumb|170px|A liquid with a flowing range of 2, viewed from above]]

All liquids share the following properties:
* ''All properties of [[blocks]]''
* Renewability: Renewable liquids can create new sources (see below)
* Flowing range: How many flowing liquids are created at maximum per liquid source, it determines how far the liquid will “spread”. This is a number ranging from 0 to 8. If 0, no flowing liquids are generated at all. Usually, liquids have a flowing range of 8
* Viscosity: How slow [[player]]s move through it and how fast new flowing liquids are created (i.e. how fast the liquid spreads)
* Drowning damage: If set, it will a) reduce your [[Player#Breath|breath]] (“bubbles”) while you are inside and b) will cause this amount of damage to you every 2 seconds if you ran out of breath while inside

== Behaviour ==


=== Creation of liquid sources ===
Renewable liquid sources create new liquid sources at open spaces. A new liquid source is created when:

* Two renewable liquid blocks of the same type touch each other diagonally
* These blocks are also on the same height
* One of the two “corners” is open space which allows liquids to flow in

When those criteria are met, the open space is filled with a new liquid source of the same type.

== Interaction with liquids ==
=== Swimming and diving ===
Swimming in a liquid is fairly straightforward: The usual direction keys for basic movement, the jump key for rising and the sneak key for sinking. Note that the controls are different if the [[Controls#Pitch move mode|pitch move mode]] is enabled.

The physics for swimming and diving in a liquid are, in detail:

* Your movement speed in a liquid is determined by its viscosity
* If you don't do anything in a liquid, you will slowly sink
* There is no fall damage for falling into a liquid as such
* If you fall from a great height into a liquid, you will be slowed down on impact (but you don't come instantly to a halt). Depending on your speed, you might end up deep in the liquid. The slow-down effect is much stronger for liquids with a high viscosity. For a safe high drop into a liquid, you need to make sure there is enough liquid above the ground, otherwise you might still suffer fall damage by hitting the ground.
* Liquids may cause breath loss and drowning damage (see above)

=== Pointing to liquids ===
Liquids are usually not [[Pointing|pointable]]. However, all liquids can be pointed by special items. In [[Games/Minetest Game|Minetest Game]], one example is the [[bucket]]. For a full list of items which are able to point to liquids, see [[:Category:Liquid pointers]].

== Liquids in [[Games/Minetest Game|Minetest Game]] ==
The following liquids exist in Minetest Game:

Quick facts:

* Liquids can be collected by a [[bucket]].
* Liquids can flow into and destroy [[snow]].
* Lava will be cooled into [[obsidian]] or [[stone]] by [[water]], [[River Water|river water]], and [[:Category:Cools lava|other blocks]].
