Description

Thermoo - Temperature and Environment API

Thermoo is a temperature and environment library mod for Minecraft. It is meant to help provide compatibility between mods and datapacks that use temperature as a core mechanic, such as Frostiful or Scorchful. Using this mod on its own will have no gameplay or visual effects. It is designed to be used by Mods written in both Java and Kotlin, as well as Datapacks through Commands and other registries.

Developer Features and Wiki

Thermoo provides a number of useful features for developers of temperature mods and datapacks, including:

A unified framework for dealing with Temperature and Wetness/Soaking
Cross-compatibility with other Thermoo mods, without needing to specify direct compatibility patches
Powerful datapack-based Environment API
Data-driven temperature effects
Event-driven configuration of default item attributes
Robust API for working with unit-agnostic temperature records (like Celsius and Fahrenheit)
Integration with Seasons mods
Powerful commands
Extensive customizability for your own mods
Can run Server-side only with Polymer (Fabric only)

Thermoo has an extensive developer wiki on GitHub, available here. If you have trouble with something, feel free to ask in my Discord.

Configs for Modpack Authors

By itself, Thermoo should have no impact on your game. However, other mods may be installed that rely on features of Thermoo such as temperature effects and freezing. I would also recommend checking out the API Overview section of the wiki if you want to configure those mods.

Recommended Mods

Thermoo is the core of my other mods, Frostiful and Scorchful. If you want to see Thermoo in action, be sure to check it out!

License and Porting

Thermoo is licensed under LGPL-3.0. It is a mod developed primarily for the Fabric and Quilt mod loaders, with limited Neoforge support. Old versions of Minecraft will only be supported according to the LTS Policy. I have no plans to port to other loaders such as LexForge or Bukkit.
