List of shared groups

GUI-related

• not_in_creative_inventory=1: This item must not appear in the creative inventory
• not_in_craft_guide=1: Crafting recipes which have this item as a result will not be shown in a crafting guide. The item may still be shown as an ingredient.

Colors

For dyes, the color groups used in Minetest Game have been widely accepted. If you add a dye, you should add the appropriate groups. The groups have names like basecolor_white, excolor_sky_blue and unicolor_dark_green.

See game_api.txt, section “Dyes” for a detailed description and see the dye mod for an example implementation.

Object classification

These groups are used to classify something. The rating is assumed to be 1. These groups mean that the item in question is something. E.g. the group “tree=1” means the item is a tree trunk.

Basic nodes

• tree: Tree trunk
• leaves: Leaves, (pine) needles, and the like
• sand: Sand
• water: Water (source or flowing)
• lava: Lava (source or flowing)

Additional nodes

• wood: Block of wooden planks
• wool: Block of wool
• sapling: Sapling

Damage groups

• fleshy: Normally for living things like animals and the player. This could imply some blood effects when hitting. Also de facto considered the “default” group for players and animals, unless your game wants to have a more sophisticated damage system
