## Groups
This document explains all the groups used in this subgame.

### Special groups

* `not_in_creative_inventory=1`: Item will not be shown in creative inventory
* `not_in_craft_guide=1`: Item will not be shown as result or fuel item in crafting guide (but still may be shown as ingredient)

### Groups for interactions

* `dig_by_water=1`: Blocks with this group will drop when they are near flowing water
* `cultivatable=2`: Block will be turned into Farmland by using a hoe on it
* `cultivatable=1`: Block will be turned into Dirt by using a hoe on it
* `flammable`: Block helps spreading fire and gets destroyed by nearby fire (rating doesn't matter)
* `soil=1`: Saplings and other small plants can grow on it
* `soil_sapling=2`: Soil for saplings. Intended to be natural soil. All saplings will grow on this
* `soil_sapling=1`: Artificial soil (such as farmland) for saplings. Some saplings will not grow on this
* `soil_sugarcane=1`: Sugar canes will grow on this near water

* `disable_suffocation=1`: Disables suffocation for full solid cubes (1)
* `destroys_items=1`: If an item happens to be *inside* this node, the item will be destroyed

#### Footnotes

1. Normally, all walkable blocks with the default 1×1×1 cube as a collision box (e.g. sand,
   gravel, stone, but not fences) will damage the players while their head is inside. This
   is called “suffocation”. Setting this group disables this behaviour

## Fake item groups
These groups put similar items together which should all be treated by the gameplay or the GUI as a single item.
You should not add custom items to these groups for no good reason, this is likely to cause a ton of conflicts.

* `clock=1`: Clock
* `compass`: Compass (rating doesn't matter)

This has the following implication: If you want to use a compass or clock in a crafting recipe, you *must*
use `group:compass` or `group:clock`, respectively.
