Armour Weight
Armour Weight replaces the usual armour setup with a weight system, so heavier pieces give more defence at the cost of speed.
What it does
Players no longer enter battle with a full set of netherite and nothing else to consider. Each armour item carries a weight, and heavy armour offers better defence while slowing the wearer down. The mod is built around unique armour layouts, so the choice of pieces matters more than the material alone.
Weights can be extended for modded armour in two lines of code, or with a datapack and no programming. A datapack file under the weightdata folder sets the item's namespace, path, weight and slot type, and decimal weights are accepted. Items with a missing or broken weight receive an automatically generated value, so the mod's own entries should be checked.
Armour Weight needs Cloth Config API and Fabric API. It runs server-side only, so players join without installing it. Builds cover 1.19 – 1.20.4 on Fabric and Quilt, and the latest file is 1.7 for 1.20.4, released under the MIT License as open source. The mod also adds Trinkets support and a more configurable config setup.
Key features
Weight per armour item
Each armour piece carries a weight that affects defence and movement, so loadouts become a trade-off.
Datapack weight definitions
Weights are defined in JSON files under the weightdata folder, with an id namespace, id path, weight and armour type.
Slot types
Armour is grouped as boots, head, chest, leggings or other, and any value outside those four is handled as other.
Trinkets support
Armour worn in Trinkets slots is counted by the same weight system.
Configurable behaviour
A config file lets server owners adjust how the weight system behaves.
