Liquids are special dynamic blocks in Minetest.
Liquid forms
Liquids usually come in two forms: In source form and in flowing form.
Liquid source
Liquid sources have the shape of a cube. A liquid source will generate flowing liquids around it from time to time, and, for renewable liquids, it also generates liquid sources (see below).
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
All liquids share the following properties:
- All properties of blocks
- Renewability: Renewable liquids have the property that new sources can be created (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 players 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 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
Creation of liquid sources
Renewable liquid 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.
2 liquid sources (S) touch each other diagonally, but are seperated by solid blocks.
The solid block at the top “corner” has been removed and a completely new liquid source block fills the empty space shortly after.
For comparison, a non-renewable liquid just flows (F) instead.
Liquids in Minetest Game
The following liquids exist in Minetest Game:
| Liquid | Renewable? | Flowing range | Viscosity | Drowning damage | |
|---|---|---|---|---|---|
 |
Water | Yes | 8 | 1 | 
|
 |
River Water | No | 2 | 1 |
|
 |
Lava | No | 8 | 7 |
