Groups

Groups is a concept for nodes, items and tools in Luanti. Any of these may be a member of a group or multiple groups, or none at all. Groups are used mainly for crafting recipes, to determine damage, to determine digging time and lots of other stuff as well.

{{< notice info>}}Below are some sample groups from Minetest Game. Mods often remove or heavily modify these groups, so they may not apply to other games.{{< /notice >}}

List of ordinary groups used by crafting recipes

• wood
• stone: Stone, Cobblestone, Stone Brick, Desert Stone, Desert Stone Brick
• sand: Sand, Desert Sand
• flora: Flowers (White Dandelion, Yellow Dandelion, Blue Geranium, Rose, Tulip, Viola), and other small plants
• leaves

• choppy: something that can be cut using force; eg. trees, wooden planks. Axes are great chopping these down.
• fleshy: living things like animals and players. Swords deal great damage to them.
• snappy: something that can be cut using fine tools; eg. leaves, small plants, wire, sheets of metal. Swords can be used to dig these, but they wear out quickly.
