New Developer Wiki

• The Thermoo Wiki has moved! It has been moved to a new MkDocs-powered wiki available at https://thermoo.thedeathlycow.com/
• Along with the new wiki site, the wiki has been largely restructured and many pages have received updates.
• Contributors can also now contribute to the wiki via pull request on GitHub.

Environment API

This is a large new API with a mix of datapack and mod-based components. I would highly recommend reading the Environment API Overview on the new wiki before going out and trying to implement it in your mods.

• Introduced a new datapack-based Environment API to control environment temperature changes.
• All methods in the Environment Controller have been replaced with a new, more fit for purpose alternative.
• The fundamental change here is that the Environment datapack registry now computes a Temperature for a biome in a some widely recognised temperature unit (Celsius, Fahrenheit, Kelvin, or Rankine), as well as a few other parameters, and then those parameters are converted into temperature point changes by an event listener.
• Added the datapack registry thermoo/environment. Format: https://thermoo.thedeathlycow.com/datapacks/environment_definition/
• Added the datapack registry thermoo/environment_provider. Format: https://thermoo.thedeathlycow.com/datapacks/environment_provider_definition/
• Added environment resistance attributes, thermoo:environment_heat_resistance and thermoo:environment_frost_resistance.
• The environment resistance attributes represent a percentage chance to "dodge" the temperature change calculated from the events in ServerPlayerEnvironmentTickEvents each time they are applied.

The full list of method replacements is as follows:

• getBaseValueForAttribute() -> ThermooAttributes#baseValueEvent()
• getLocalTemperatureChange() -> The Environment Datapack Registry
• getEnvironmentTemperatureForPlayer() -> ServerPlayerEnvironmentTickEvents.GET_TEMPERATURE_CHANGE
• getTemperatureEffectsChange() -> LivingEntityTemperatureTickEvents.GET_ACTIVE_TEMPERATURE_CHANGE
• getFloorTemperature() -> LivingEntityTemperatureTickEvents.GET_PASSIVE_TEMPERATURE_CHANGE
• getMaxWetTicks() -> The entity attribute thermoo:max_soaking_tick_multiplier (on 1.21.1, the name is thermoo:generic.max_soaking_tick_multiplier)
• getSoakChange() -> LivingEntitySoakingTickEvents.GET_SOAKING_CHANGE
• getHeatAtLocation() -> LivingEntityTemperatureTickEvents.GET_PASSIVE_TEMPERATURE_CHANGE
• applyAwareHeat() -> LivingEntityTemperatureTickEvents.ALLOW_ACTIVE_TEMPERATURE_CHANGE
• getHeatFromBlockState() -> removed
• isHeatSource() -> removed
• isColdSource() -> removed
• isAreaHeated() -> removed

Item Attribute Modifier Event

• Added an experimental ModifyItemAttributeModifiersCallback.EVENT that is very similar to the previous Fabric API event of the same name.
• This applies attribute modifiers to an entity when they equip or unequip an item, it does not actually modify the underlying minecraft:attribute_modifiers component of an item stack.

Kotlin Bindings

• Added new Kotlin-specific method and field extensions to TemperatureAware and Soakable.
• These methods allow Kotlin users to use these interfaces in an intuitive way and without having to add a thermoo$ prefix to all methods.
