Groups/Custom groups

This page lists the various groups which are mainly used in subgames and mods.

(Note: If not group rating is specified, a rating of 1 is assumed.)

Subgames

Minetest Game

These are the custom groups used by Minetest Game. Many groups listed here have also been adopted by mods and subgames which are not directly related to Minetest Game, but be careful, the intention may not always be equal!

Digging time groups

The following groups determine digging times. The rating can be between 1 and 3; higher ratings result in slower digging.

• crumbly: dirt, sand
• cracky: tough but crackable stuff like stone.
• snappy: something that can be cut using fine tools; eg. leaves, small plants, wire, sheets of metal
• choppy: something that can be cut using force; eg. trees, wooden planks
• fleshy: Living things like animals and the player. This could imply some blood effects when hitting.
• explody: Especially prone to explosions
• oddly_breakable_by_hand: Can be added to nodes that shouldn't logically be breakable by the hand but are. Somewhat similar to dig_immediate, but times are more like {[1]=3.50,[2]=2.00,[3]=0.70} and this does not override the speed of a tool if the tool can dig at a faster speed than this suggests for the hand.
