Comparison of stone and water blocks

Liquids are blocks that can, as the name suggests, flow and spread.

Usage

There are currently only two liquids in Minecraft: Lava and water.

How liquids work

File:2011-09-22 09.54.38.png

Lava seeping through one layer of dirt.

Liquids are cellular automata. The rules appear to be as follows:

Falling liquid

An air block below a liquid block is converted into a liquid block of that type. This happens faster for water than for lava (except in the Nether).

Liquids that are suspended above an open area by one block thick of material will seep through the material and drip to the floor. Lava particles that are seeping do not cause damage or start fires. This makes digging upwards safer, since you can tell if you are near a lava/water lake.

Liquid level

Each liquid block has a level value. Source blocks have a level of 0, and the maximum level depends on liquid type.

Note: The "level" value increases as the water is further from the source. A high level value means that the water is actually physically downhill.

Still liquids

To keep track of which blocks are actively flowing, water and lava each have a pair of block IDs. For water, there is water (8) and still water (9). Still water will stay in place until it receives a block update. Water updates periodically and will change itself to still water when it cannot spread any further.

Updating a block next to still water will turn it back to water so it can spread some more.


Liquid block update cases

The state of a liquid block only updates in certain cases:

  • On creation
  • If one of the 6 neighboring blocks' state changes.
  • If its own level changes

State changes that cause an update include:

  • Adding or removing a block
  • A neighboring block's level changes
  • A redstone wire switches on or off

Liquid block update process

When a liquid block updates, it performs the following checks.

  • Check inward flow
If there is a liquid block of the same type above, set level to 1
Otherwise, reduce or increase level in steps of 1 so that it is 1 higher than the one of its 4 neighbouring block with the lowest level*
If level is increased past the max level, replace liquid block with air block.
Level cannot be decreased below 1

* This does not affect source blocks (level = 0)

  • Check outward flow
This only happens for liquid blocks of less than the max level value
Determine the shortest distance to a fall, but only scan 5 blocks distance*
If any of the directions tied for shortest have an air block, convert that air block to a liquid block with a level of 1 more than the current block*

* This means that lava will flow towards a drop that it cannot reach.

Source creation

A water block is converted into a source block if both of the following conditions hold:

  • it is bordered by at least 2 water source blocks on the same horizontal level.
  • the block underneath is a solid block or a water source block.

Lava source blocks cannot be created.

Mixing of liquids

If a liquid flows into a block occupied by another liquid, then the block turns into a solid block according to the following rules:

  • If Water flows into a lava source block, then obsidian is produced.
  • If Lava flows downward into Water, then stone is produced.
  • if Water flows horizontally into downwards flowing lava, nothing happens.
  • Otherwise, cobblestone is produced.

When determining the shortest distance to a drop, other liquid blocks are assumed to be equal to air.

== Usage ==
Obsidian boats sank in [[water]] instead of floating. They also sank in lava like other boats but did not get destroyed in it.

== Sounds ==
Obsidian boats used the Friendly Creatures sound category for entity-dependent sound events, although did not have any sounds of their own.

'''Raw cod''' is a [[food]] item that can be eaten by the player or cooked to make [[cooked cod]].

== Obtaining ==

=== Mob loot ===

==== Cod ====
[[Cod]] always drops 1 raw cod when killed, unaffected by Looting.<ref>{{bug|MC-212795||Salmon & Fish mobs are not affected by Looting}}</ref> If it is killed while on [[fire]], it drops 1 [[cooked cod]] instead.

==== Dolphins ====
When killed, [[Dolphin|dolphins]] drop 0–1 raw cod. The maximum amount is increased by 1 per level of [[Looting]], for a maximum of 0-4 with Looting III. If killed while on fire, they drop cooked cod instead.

==== Guardians and elder guardians ====

[[Guardian]]s and [[elder guardian]]s have a 40% and 50% chance, respectively, to drop raw cod when killed. {{IN|java}}, cooked cod is dropped if a guardian is on fire when killed.

Guardians and elder guardians also have a 2.5% chance to drop a random fish, with 60% of them being raw cod, which drops as cooked if the guardian was on fire. The chance of getting the fish drop is increased by 1% per level with [[Looting]] (for a maximum of 5.5% with Looting III), but the type of fish is not affected.

==== Polar bears ====

[[Polar bear]]s have a 75% chance of dropping 0–2 raw cod when killed. The maximum amount can be increased by 1 per level of Looting, for a maximum of 0-5 with Looting III. If killed while on fire, they drop cooked cod instead.

=== Fishing ===
{{main|Fishing}}

Raw cod can be obtained from fishing. The wait time of one being caught is decreased with the [[Lure]] enchantment and the chance of one being caught is slightly decreased with the [[Luck of the Sea]] enchantment (named as such because it increases treasure, not fish).

Catching cod awards 1-6 experience.

=== Natural generation ===
{{el|java}}{{LootChestItem|raw-cod}}

=== Villager gifts ===
{{in|java}}, fisherman [[villager]]<nowiki/>s throw raw cod at [[player]]s under the [[Hero of the Village]] effect.

== Usage ==

=== Smelting ingredient ===

{{smelting
|Raw Cod
|Cooked Cod
|0.35
}}

=== Food ===

Raw cod restores {{hunger|2}} [[hunger]] and 0.4 [[Hunger#Mechanics|saturation]].

=== Cats ===

Raw cod can be used to tame [[cat]]s with {{frac|1|3}} chance of success, get cats off of [[chest]]s, and [[bed]]s, [[breed]] cats, and make baby cats grow up faster by 10% of the remaining time. Additionally, raw cod can be used to heal cats by {{hp|2|mob=1}}.

Raw cod can be used to gain [[ocelot]] trust, breed ocelots, and make baby ocelots grow up by 10%. 

=== Dolphins ===

[[Dolphin]]s can be fed raw cod. Doing this improves their trust and interaction with the player. However, unlike most animals, feeding dolphins does not allow them to breed.

When a player feeds raw cod to a dolphin, it swims toward the nearest chest in an [[underwater ruins]] or [[shipwreck]]. If the chest in the nearest structure is broken, they swim to the next nearest structure that has a chest.

===Trading===

Fisherman villagers have 50% chance to sell 6 cooked cod for 6 raw cod and 1 [[emerald]] as part of their first tier trade.

Apprentice-level fisherman villagers have a {{frac|2|3}} chance to buy 15 raw cod for an emerald in Java Edition, and always offer the same trade in Bedrock Edition.

=== Wolves ===
{{IN|bedrock}}, raw cod can be used to feed [[wolves]], to heal them by {{hp|2|mob=1}}. However, unlike other meat items, raw cod cannot be used to speed up the growth of baby wolves nor used to breed them, thus making it only feedable when wolves are not at full health.

Beta 1.9-pre5A lava block could be converted into a source block if the following conditions were met:
  • it is bordered by 4 lava sources in a cross-like arrangement
  • the 4 sources are on the same horizontal level as it
  • there is a solid, opaque block underneath it
?Lava source blocks can no longer be created.
