Changelog

All notable changes to Catalyst will be documented in this file.

[0.2.3] - 2026-02-05

Added

  • Search Functionality: Added comprehensive search bar to settings GUI with real-time filtering
    • Search across all settings with keyword matching
    • Dynamic UI generation for search results with interactive controls
    • Clear search when switching tabs
  • UI Components: Created reusable search result templates for checkboxes and sliders

Fixed

  • Field Sync Consistency: Fixed missing field syncs in Catalyst.syncConfigToInjectedFields() for visual effects and BlockType cache settings
  • Visual Effects Toggle: Fixed particle and animation toggles not syncing to injected Hytale class fields at runtime
  • Bytecode Generation: Fixed initStaticInt() bug that generated incorrect bytecode for value -1 (now correctly uses ICONST_M1)
  • BlockType Cache: Fixed cache never being populated on miss - now properly stores results before returning
  • Search Results Display: Fixed search results list visibility and proper clearing between searches

Changed

  • Code Quality: Replaced hardcoded magic numbers with constants from CatalystConfig in reset-to-defaults logic
  • Documentation: Improved comment clarity in FloodLightCalculationTransformer for parameter index calculation
  • Cleanup: Removed unused ldcCount field in ChunkGeneratorTransformer
  • Search Architecture: Refactored search system to use indexed selectors for dynamic UI elements
  • README Style: Adopted clean emoji-based headers like create-go-app/cli for better readability
  • Installation Instructions: Updated to reflect both early-plugins and mods folder requirements
  • Command System: Simplified main command to /catalyst instead of /catalyst menu

[0.2.2] - 2026-01-26

Fixed

  • Chunk Generation Stability: Fixed chunk corruption and disappearing chunks caused by multiple transformers modifying the same class
    • Consolidated ChunkPoolSizeTransformer, ChunkCacheSizeTransformer, TintInterpolationTransformer, and HeightSearchTransformer into single ChunkGeneratorTransformer
    • Consolidated LightPropagationOptTransformer, OpacityLookupCacheTransformer, LightQueueOptTransformer, and LightingDistanceTransformer into single FloodLightCalculationTransformer
  • Transformer Class Matching: Fixed transformers not matching target classes due to incorrect class name format (now uses dot notation for matching)

Added

  • UI Tooltips: Added descriptive tooltips to all settings UI elements explaining what each optimization does

Changed

  • Simplified Architecture: Removed CommandRegistrationTransformer and AssetRegistrationTransformer - command/asset registration now handled by standard JavaPlugin lifecycle
  • Fixed Visual Effects Transformers: ParticleToggleTransformer and AnimationToggleTransformer now inject static fields directly into target classes instead of referencing external classes
  • Code Cleanup: Removed unused reflection-based registration methods from CatalystEarlyInit

Technical

  • Transformers now correctly use dot notation (com.example.Class) for shouldTransform() matching and slash notation (com/example/Class) for bytecode operations

[0.2.1] - 2026-01-22

Removed

  • Lazy Loading Optimizations: Completely removed lazy loading features (Lazy Block Entities, Lazy Block Tick, Lazy Fluid Processing) as they only performed throttling without actual optimization benefits
    • Removed LAZY_BLOCK_ENTITIES_ENABLED, LAZY_BLOCK_TICK_ENABLED, LAZY_FLUID_ENABLED config fields
    • Removed BlockModuleMixin, BlockTickPluginMixin, FluidPluginMixin mixin classes
    • Removed lazy loading UI toggles and event handlers
    • Removed lazy loading from metrics and menu displays

Changed

  • Settings UI Improvements:
    • Moved Reset to Defaults button outside of tab panels to stay fixed at bottom
    • Simplified slider options by removing redundant checkboxes - sliders are now standalone
    • Fixed tab button highlighting - selected tab now properly changes background when switching tabs
    • Tab buttons now use direct Background property for dynamic styling
  • Menu & Metrics: Updated to show Runtime Optimizations instead of removed Lazy Loading options

Added

  • New Transformers: Added multiple bytecode transformers for various optimizations:
    • Animation and Particle toggle transformers
    • Biome/Tint interpolation transformers
    • Chunk cache, pool size, and parallel generation transformers
    • Lighting optimizations (batch, distance, propagation, queue, flat cache, packed ops)
    • Height search and opacity lookup cache transformers
  • Visual Effects Toggle: New utility class for particle and animation control
  • Config Persistence: Added CatalystEarlyInit for config file loading/saving

[0.2.0] - 2026-01-21

Added

  • Entity Distance Control: Configurable entity view distance multiplier (default: 1.0)
    • Adjusts how far entities are visible/processed
    • Lower values improve server performance
  • Chunk Rate Control: Configurable chunks processed per tick (default: 1)
    • Limits chunk loading speed to prevent server lag spikes
  • Pathfinding Optimization: Configurable pathfinding timeout reduction (default: 50%)
    • Reduces CPU usage from entity pathfinding calculations
  • Reset to Defaults Button: One-click reset in settings GUI to restore all defaults
  • Optimization Metrics: Track performance impact of enabled optimizations

Changed

  • UI Redesign: Complete settings UI overhaul following Hytale design patterns
    • Organized into logical sections with color-coded headers
    • Fixed position elements (reset button at bottom)
    • Removed missing texture references that caused red backgrounds
    • Improved layout with proper scrolling sections
  • Slider Values Fixed: Corrected property type from .Text to .Value for numeric sliders
  • Improved transformer base class: Better error handling and logging

Fixed

  • Fixed slider value setting error (now uses correct .Value property)
  • Fixed red background in UI sections (removed missing texture reference)
  • Fixed reset button position (now at fixed bottom position, not scrolling)
  • Fixed checkbox value binding in settings UI

[0.1.1] - 2026-01-19

Added

  • Hyxin Compatibility: Full support for the Hyxin Mixin framework
    • Added Mixin classes (BlockModuleMixin, BlockTickPluginMixin, FluidPluginMixin)
    • Added catalyst.mixins.json configuration
    • Works seamlessly alongside ASM transformers
  • Dual-mode operation: Catalyst now works both standalone (ASM) and with Hyxin (Mixin)

Changed

  • Java 21 target: Downgraded from Java 25 to Java 21 for broader compatibility
  • ASM relocation: Bundled ASM classes relocated to com.criticalrange.asm to prevent classloader conflicts with Hyxin
  • Build system: Migrated to Shadow plugin for proper dependency shading

Fixed

  • Fixed typo in settings UI ("CATALYT" -> "CATALYST")
  • Resolved ASM version conflicts when running alongside Hyxin

[0.1.0] - Initial Release

Added

  • Core bytecode transformation system using ASM
  • Lazy Block Entity Loading: Defers BlockModule.onChunkPreLoadProcessEnsureBlockEntity() calls
  • Lazy Block Tick Discovery: Defers BlockTickPlugin.discoverTickingBlocks() calls
  • Lazy Fluid Processing: Defers FluidPlugin.onChunkPreProcess() calls
  • In-game settings GUI for toggling optimizations
  • /catalyst command for runtime configuration
  • Early plugin architecture for Hytale server integration
