Sleep Deprivation
by JohnSeagull
Sleep Deprivation applies progressively harsher penalties to players who go a long time without sleeping, and the server owner sets how severe they become.
What it does
Penalties start once a configurable stage begins, and each stage can be disabled by setting its value to -1. Among the effects are inventory scrambling, which controls how many slots are shuffled and whether the hotbar is included, and ghost items, which show a set number of fake duplicates per player one time. Each effect has its own intensity on a 0 to 10 scale, and a message in the actionbar announces when a player passes a threshold.
The mod runs on the server alone, so players join without installing anything. Fabric API is required, and Mod Menu is an optional dependency. Inventory modification effects and their messages can be turned off independently for servers where those effects are not wanted. Files are published for Fabric only, with builds for 26.1 – 26.1.2 and 2.6+26.1 as the latest file. The code is not open source, and the mod is released under All rights reserved.
Key features
Staged sleep penalties
Negative effects grow stronger as a player goes longer without sleep, with each stage set in the configuration.
Inventory scrambling
Slots are shuffled by a configurable amount, and the hotbar can be included in the scramble.
Ghost items
A set number of fake duplicate items can appear for each player, once.
Adjustable effect intensity
Each effect has a potency on a 0 to 10 scale, so server owners can tune how harsh the penalties feel.
Independent messages
Inventory effect messages can be turned off separately from the effects themselves.
