# Mass Minecraft should care what you are carrying. Mass gives every item a weight. Carry too much and you slow down, lose sprint, lose jump, sink in water, and make horses regret meeting you. ## What it does - Tracks weight across armor, hotbar, inventory, and offhand - Slows movement as your load goes up - Disables sprint and jump at higher weight tiers - Makes heavy players sink in water - Slows horses and counts chest cargo on horse-type mounts - Blocks elytra when you are over the limit - Adds the `Lightening` enchantment to make armor lighter A diamond chestplate weighs 8 kg. Full diamond is enough to matter. Full netherite is a life choice. ## Install - Use Paper `1.21.11+` - Drop the jar into `plugins/` - Start the server once - Edit `plugins/Mass/config.yml` if you want different weights or penalty thresholds - Run `/mass reload` ## Commands All commands use `mass.admin`. - `/mass reload` - `/mass info ` - `/mass lore ` - `/mass item set <kg>` - `/mass item clear` - `/mass give lightening ` ## Config The config is where most of the real control lives. You can change: - item weights - category defaults - sprint and jump thresholds - water sinking - horse slowdown - elytra limit - enchantment settings If you want the plugin to feel punishing, you can do that. If you want it lighter and more survival-friendly, you can do that too. ## Build ```bash mvn clean package ``` Output goes to `target/Mass-1.2.jar`. ## Notes - Stackable items do not get lore or extra item data that would break stacking - The plugin uses `Lightening`, not `Lightning`. That is on purpose - If something feels off, check the config first. Most of the balance lives there ## Discord If you want updates, feedback, or bug reports, join the Discord: (https://discord.gg/WQ628mcr4w)
