Material Json

Material definitions are JSON files loaded from datapacks. A datapack can change any single field, such as durability alone, and leave the others at their defaults, so a change does not require copying a whole material. Each material file sets the durability as a 32-bit integer, the mining speed and attack damage as single-precision floating-point numbers, and the mining level and enchantability as integers. Armor entries add protection per piece, armor toughness, knockback resistance and the sound played when the armor is equipped, which must be a sound event defined in sounds.json.

Changes are synced from the server to connected clients and take effect after a datapack reload, so new values appear without restarting the game. The mod also has a configuration file that lets server owners alter the materials of weapons, armor and tools. Support mods can add new weapons, armor and tools that read these material definitions, and the mod is intended to be used alongside them. Individual items can receive bonus or penalty values, for example for swords.
