Equipment Weight
by TheRedBrain
Equipment Weight gives worn gear a weight, and heavier loads slow or weaken a player through status effects.
What it does
The mod registers two entity attributes: one that tracks the weight a player carries in equipment, and one that sets the limit that load is compared against. When the carried weight reaches the maximum, the mod applies a configured status effect to the living entity. Only one status effect is applied at a time.
The server config holds a map of float values to strings, where each string must be a valid identifier for a status effect. Invalid strings are ignored. With the default values, a living entity with equipment weight 5.0 and the default maximum is affected by the Haste effect, while changing the weight to 3.0 removes Haste and applies Strength instead. The ratio between the two attributes determines which configured effect applies.
The mod is built as an API for data pack authors and adds no items of its own. It is released under the MIT License and is open source. Installation needs Fabric API and Fzzy Config, and the mod runs on client and server. Files cover 1.20.1, 1.21.1, 26.1, 26.1.1 and 26.1.2, with 3.0.0 for 26.1.2 as the latest file.
Key features
Equipment weight attribute
Items can carry a generic.equipment weight value that adds to the total load of the wearer.
Maximum weight attribute
A generic.max equipment weight attribute sets the limit that the total load is compared against.
Configurable status effects
The server config maps weight ratios to status effects, so each threshold can apply a different effect.
Default values
Built-in defaults give a 10.0 maximum and a 0.0 base weight, with Haste applied at the default ratio.
