Thermoo 10.0.0 Alpha 2 for Minecraft 26.1-snapshot-11
A second pre-release build for Thermoo 10 for Minecraft 26.1. This is an alpha version, and the API remains extremely unstable as further breaking changes are planned. Because of this, the documentation has also not yet been updated! The Thermoo Docs will be fully updated when the API changes are finalized for 26.1.
This release is primarily intended for me to get a head start on updating Frostiful and Scorchful, and also to open Thermoo up to public bugtesting from whomever wants to do that.
Alpha 1
- Begun adding version numbers to API packages.
- So far this has impacted the following packages:
com.github.thedeathlycow.thermoo.api.command->com.github.thedeathlycow.thermoo.api.command.v1com.github.thedeathlycow.thermoo.api.temperature.effect->com.github.thedeathlycow.thermoo.api.temperature.status.v2
- More packages will be moved before the full 26.1 release.
- So far this has impacted the following packages:
- Removed command definition classes from API.
- These are now implementation classes.
- Renamed
*ArgumentTypeclasses to*Argumentin the command API. - Replaced the Temperature Effect API with the Temperature Status API (#104).
- Added Temperature Status Tags (#106).
Alpha 2
- Replaced
HeatingModewith a data-driven temperature sources API (#109). - Moved all remaining API packages to versioned packages, as follows:
com.github.thedeathlycow.thermoo.api.environment.*->com.github.thedeathlycow.thermoo.api.environment.v2.*com.github.thedeathlycow.thermoo.api.item.*->com.github.thedeathlycow.thermoo.api.item.v2.*com.github.thedeathlycow.thermoo.api.season.*->com.github.thedeathlycow.thermoo.api.season.v2.*com.github.thedeathlycow.thermoo.api.util.*->com.github.thedeathlycow.thermoo.api.util.v1.*(these classes may still be split up to more specific packages)com.github.thedeathlycow.thermoo.api.client.*->com.github.thedeathlycow.thermoo.api.client.v1.*
- Moved the
ThermooRegistriesandThermooRegistryKeysclasses to aregistrypackage in the core API - Moved the
predicatepackage andThermooAttributesclass to a new entity API package:com.github.thedeathlycow.thermoo.api.entity.v1 - Split the
ItemandEntityTypetags inThermooTagsinto classes in the entity API (ThermooEntityTypeTags) and item API (ThermooItemTags), respectively - Removed
ThermooTags. - Usage of
GuiGraphicsinStatusBarOverlayRenderEventswas replaced withGuiGraphicsExtractor
Data-driven Temperature Sources
- Moved all classes and packages under
com.github.thedeathlycow.thermoo.api.temperature.*EXCEPT for thestatuspackage tocom.github.thedeathlycow.thermoo.api.core.v1. - Removed the
HeatingModeandHeatingModesclasses. - The method
TemperatureAware#thermoo$addTemperature(int, HeatingMode)was converted toTemperatureAware#thermoo$addTemperature(int, TemperatureChange). TemperatureChangenow stores information about the context of individual temperature changes, including source, cause, direct cause, and position, and this data is now passed to various temperature change related events.- Added a new
ThermooLevelinterface that is injected onto allLevelinstances by mixin.ThermooLevelprovides access to a set of shared instances ofTemperatureChange.
- The
ALLOW_X_UPDATEandALLOW_X_CHANGEevents inLivingEntityTemperatureTickEventswere removed and replaced with more general events inTemperatureChangeEvents. - The
GET_X_CHANGEevent inLivingEntityTemperatureTickEventsis now a source-key mapped event returned bygetTemperatureChangethat allows for the same sort of event to apply to any temperature source - except absolute and environment sources. - The
/thermoo temperature (add|remove)sub-commands now provide more ability to specify context about a temperature change withatandbysyntax, essentially to provide the data for theTemperatureChangeclass.
Example Migration
A simple migration of adding temperature:
void foo(LivingEntity e) {
- e.thermoo$addTemperature(10, HeatingModes.ACTIVE);
+ e.thermoo$addTemperature(10, e.level().thermoo$temperatureSources().active());
}
Temperature Status API
The Temperature Effect API was rewritten and renamed to the Temperature Status API to better distinguish between the JSON files (statuses) and the effect types that actually do the work. The API largely does the same thing, but here is a summary of the changes:
- Replaced the
thermoo/temperature_effectregistry withthermoo/temperature_statusregistry - The new status registry is now an actual registry, which supports tags, synchronisation, and
Holders, and all that. - Replaced
configobjects with a directeffectslist entry. - Moved type delegation to entries of the effects, rather than at the root of the registry object.
- Merged the
attribute_modifierandscaling_attribute_modifierinto a single type, differentiated with a field. - Removed the
emptyandsequencetypes, they are no longer needed. - Added a way to define the application order of statuses with the
thermoo:application_ordertemperature status tag.
This also removed some functionality:
- Temperature statuses can no longer be "hot reloaded"; you must restart the server to reload them.
- There is no longer a
loading_priorityfield. The intended functionality behind this was to allow Thermoo Patches to override the effects from Frostiful/Scorchful with a check for Origin. This was superseded by the enable API. It is not known if anyone else used this for any particular functionality that was actually necessary, so it is being removed.
