Description

WeatherCore

WeatherCore is an intrusive core library mod that overhauls Minecraft's hardcoded weather system, replacing it with a flexible weather system with the possibility of registering new weather types.

For users

Installed alone, this mod doesn't alter vanilla weather, but might alter the way Minecraft choose its next weather due to replacing the hardcoded weather timers with a complex weather management system.

Only install WeatherCore if a dependency requires it.

Key Features

  • Custom weather registry: Register custom weather conditions.
  • Weather management: Replaces vanilla's basic timers with a management system.
  • Scoping: A scope defines the zones a weather condition affects inside a level. Weather themselves are not "aware" of what scopes they own so any custom weather conditions can be summoned globally or centered.
  • Replaces /weather command and adds a /toggledownfall command.

Weather scopes

Any custom weather condition created with this library will own a scope when summoned. It can either be:

  • Global Scope (dimension wide)
    • Perfect for vanilla style weathers
    • Affects the entire dimension
  • Centered
    • Ideal for events, like a fallout after a nuclear explosion or a cursed fog after activating a mysterious monolith.
    • Good for letting players decorate their builds
    • Maybe good for tornadoes? Why not use entities instead?

Development

WeatherCore is currently under active development and is mostly bespoke to my own projects. I am looking for feedback from other developers to make the mod more universally useful and ensure it integrates smoothly with other mods.

If you want to use WeatherCore, use the artifact from Modrinth's maven:

repositories { maven { name = "Modrinth" url = "https://api.modrinth.com/maven" } } dependencies { modImplementation "maven.modrinth:weathercore:mc1.21.1-0.1.0" }
