Lous temperature
by Lous12
Lous temperature is a Fabric survival mod that tracks environment and body temperature, with a configurable system the player sees on a simple HUD.
What it does
Lous temperature keeps the environment temperature separate from the body temperature. The outside value depends on biomes, altitude, day and night, and weather, and it shifts near heat and cold sources, while water and lava also change the local reading. The body temperature follows the environment over time, and the simple HUD shows where it stands.
The mod is a foundation for survival overhauls rather than a finished survival layer. Most of its systems can be switched off independently, datapacks can register custom heat and cold sources, and more complex mechanics are meant to arrive as separate addons. Debug and reload commands help server owners test settings.
Fabric API is required. Servers that run it need every player to install it too. Files are published for 1.20.1 – 1.21.11 and for 26.1 – 26.2, and the latest Fabric file is 1.2.0 for 1.20.1, dated 2026-09-04. The mod is open source under the MIT License, and its source code is public.
Key features
Separate temperature values
Environment temperature and body temperature are tracked as two values, so the outside conditions can be read apart from the player's state.
Heat and cold sources
Nearby blocks and fluids such as water and lava change the local temperature, and datapacks can add further sources.
Configurable body temperature
The body temperature system can be tuned, and most of its parts can be disabled one at a time.
Simple HUD and debug commands
A compact on-screen readout shows the current temperature, and reload and debug commands support testing.
