Fzzy Core Mod (1.20.1, 1.19.4) is the base API that powers some kotlin mods made by fzzyhmstrs (that’s me!). Besides offering some basic utility functions that come in handy for many different types of mods, Fzzy Core includes the basic framework of the Modifier System, a flexible and powerful system for modifying… almost anything!

Features:

Coding Utilities

  • Base Enchantment Class easily integrates with config systems for enabling/disabling enchantments.
  • Text Wrapper to simplify multi-version support and avoid text merge conflicts.
  • Persistent Effect System for delayed or repeating events independent of object ticks.
  • Particle System for placing client-side particles at specific player viewpoints.

Synced Configuration System

  • Automatically syncs server configs to joining clients.
  • Supports version control and automatic config updates.
  • Uses Kotlin features for clean and simple implementation.

Custom Flavor Items

  • Allows items with flavortext or description text directly in lang files.
  • Supports additional methods for custom text behavior.

Mana Items

  • Provides a simple framework for items that consume mana instead of durability.

Modifier Framework

  • A flexible alternative to the vanilla Enchanting System.
  • Permanent modifiers that cannot be removed (e.g., grindstones won’t affect them).
  • Modifiers are self-contained and can represent tiered states like “Rusty → Shiny → Gleaming”.
  • Includes built-in tools for displaying modifiers in tooltips.
  • Supports both simple attribute modifiers and complex, effect-driven modifiers (as in Amethyst Core).

NBT Utilities

  • Helpers for reading/writing BlockPos data easily.
  • Tools for working with NbtLists (add, read, remove).
  • ItemStackId system for assigning unique identifiers to items.
  • Transfer non-enchantment NBT between item stacks with a helper method.

Raycaster Utility

  • Server-side raycasting to detect blocks or entities without extra networking.
  • Supports detection of entities with rotated hitboxes, ideal for advanced targeting mechanics.

Event Registry

  • Manages tick-based events not tied to specific entities.
  • Includes prebuilt 1s, 1.5s, and 2s clocks for periodic logic.

Item Model Registry

  • Registers custom item models for different render modes (in-hand, on-ground, etc.).
  • Integrates with Fabric BuiltinItemRendererRegistry.DynamicItemRenderer.

Effect Queue

  • Unifies multiple status effects to avoid GUI flickering or effect swapping.

Trinket Utilities

  • Optional integration with Trinkets mod.
  • Provides getTrinketStacks for accessing equipped trinkets.
  • Supports AugmentTasks for trinkets with active or passive abilities.
