This version brings Breaking Changes.

Updating might make your mod incompatible with previous versions of the Library.

2.0.0

Added

Variant Loader

  • Added a fallback variant parameter to getParameterDataFromVariant, allowing shared data to be centralized in a single JSON instead of duplicating it per variant.
  • Reworked the entire Loading system to have the Events on the Library side and allow Developers to just inject the path and entities.
    • Instead of handling everything themself.
    • All Developers can now remove their ReloadHandler since it became redundant and has been replaced with a way cleaner and more optimized system.
    • For more details, visit the Wiki.
  • onReload has been modified to onDatapackSync.

Logging

  • Added a new /log command accessible to users with a permission level of 3 or higher (/op).
    • This command opens an in-game menu displaying console logs, allowing developers to monitor output directly without needing terminal access.
    • Supports log levels with color-coded formatting for easier readability.
  • isLoggingEnabled has been moved to a server sided config.
  • All Logging is now translatable through Minecrafts Component System!
  • Added a ton more ways to Log stuff to match the slf4j system.

Network Handler

  • Introduced a streamlined network registration system.
    • Simplifies the use of custom packets by automatically handling registration internally via BlueLib.
    • Packet definitions and handlers are now separated into two distinct classes for better structure and maintainability.
    • For more details, visit the Wiki.

Packets

Variant Data Synchronization

  • AllDataPacket – Sends a Map<String, JsonObject> containing all variant data from the server to the client.
  • ParameterDataPacket – Sends specific parameter data for a given variant as a JsonElement.
  • VariantsPacket – Sends a Set<String> representing all available variant identifiers for an entity. ⚠️ These packets are not registered by default; they must be registered on the S2C side, with the handler provided as a lambda defining the logic to execute when the packet is received.⚠️

Changed

  • onReload has been modified to onDatapackSync.

Bug Fixes

  • Cleaned up all of the Logging we had in place.

Deleted

  • Removed IVariantEntityBase since it has become redundant!
