Cold Sweat Mod for Minecraft 1.20.1, 1.21.1
Adds a fitting and difficult temperature system to Minecraft, plus more!
About the Cold Sweat mod
Cold Sweat is a Vanilla-friendly, deeply customizeable, and performant temperature mod for Minecraft. It leverages an advanced temperature system to give a well-rounded experience, packed with features that help or harm you.
A prepared player can weather the elements of Minecraft's hostile environments, but if you strand yourself in the middle of nowhere, there's no second chance!
A dynamic temperature system that is affected by the world and the player (biomes, blocks, items, weather, altitude, etc.)
Items and blocks that help the player survive against the world
Insulate armor to resist the elements
Stay next to blocks to warm up or cool down
The thermometer shows precise temperature
Use waterskins for quick relief or as cooling/heating packs
Detailed in-game and file-based configs

In vanilla, every biome has its own temperature. This mod uses that property for the temperature system, which means that this mod should be compatible with almost all modded biomes (given their temperatures are configured correctly ;) ).

How to install Cold Sweat

Install Millida Launcher
The launcher is free: download it at millida.net/launcher and sign in with any nickname.

In the version list above, pick the file ColdSweat-2.4.5-a2.jar (2.5 MB) for your game version and loader.
Put it in the mods folder
The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it.
Launch the loader profile
Open “Mods” in the main menu: Cold Sweat should be in the list.

A server on Forge or NeoForge
The mod only works on a server with the same loader and game version, for example 26.2.
