Lomka

Performance

• Font glyph widths cached per codepoint/bold pair — text rendering does fewer glyph source lookups. (1.21.11+) NEW
• Resource pack loading overhaul:
  • FallbackResourceManager listResources fast-path for .mcmeta — eliminates thousands of useless Identifier allocations and map lookups. NEW
  • MultiPackResourceManager bypasses redundant secondary TreeMap allocation when only one namespace manager is present. NEW
  • VanillaPackResources fast-path namespace check, zero-allocation path resolution, and cached parsed pack.mcmeta. (<26.1) NEW
• Block collision shapes now served from the cached shape instead of virtual getCollisionShape dispatch. (non-dynamic blocks) NEW
• Light queues swapped from LongLinkedOpenHashSet to bit-packed SpatialLongSet — less heap churn during chunk loading. NEW
• Shader uniform lookup via fastutil open-addressing map instead of HashMap. (1.21.6+) NEW
• ChunkedSampleByteBuf no longer allocates a fresh native buffer per chunk. (1.21+) NEW
• Lighting precomputes a buffer slice per entry and skips redundant GPU UBO writes when the cardinal light type is unchanged. (1.21.6+)
• NativeImage fillRect/copyRect rewritten with bulk MemoryUtil.memCopy — whole-image and whole-row transfers in a single call.
• Std140 builder and size calculator put* methods rewritten with bitwise alignment and absolute indexed writes. (1.21.6+)
• ModelPart rotateBy composes rotations through a single quaternion instead of a full 3x3 matrix multiply.
• ArrayListDeque removes from the front half by advancing head instead of shifting the tail.
• ARGB reciprocal lookup table computed in O(1) per entry instead of an inner loop.

Bug Fixes

• NativeImage fillRect/copyRect now validate format and bounds explicitly instead of silently corrupting memory.
• Fixed Lightmap and LightmapRenderStateExtractor 26.2 API calls (mapBuffer, getMainCamera, getBossOverlay, getNightVisionScale).
• MixinMth clampedLerp is now version-conditional so the correct argument order is used on 1.21.11+ and older.
• Camera 26.1+ near-plane path kept on the lightweight custom structure.

New

• New duck interfaces: IBitSetDiscreteVoxelShape, IGlyphSource.
• New accessors: AccessorCache, InvokerBlockBehaviour.

Compatibility

• Per-version mixin configs, access wideners and access transformers are now generated from Stonecutter templates (src/stonecutter/) instead of committed per-version files.
• Mixin source exclusions are auto-derived from the processed mixin config — no more hand-maintained exclude tables in build scripts.

Removed

• Removed low-impact mixins: MixinSamplerCache, MixinSortState, MixinQuadrant, MixinItemTransform, MixinMipmapGenerator.
• Removed DiscreteVoxelShapeHelper — replaced with the IBitSetDiscreteVoxelShape duck interface.
• Removed per-version committed lomka.mixins.json, *.accesswidener and accesstransformer.cfg files.

Changed

• Build system refactored: build-logic composite build → buildSrc with auto-derived mixin exclusions.
• 16 build variants now (added 1.20.1-fabric and 1.20.1-forge).

1.20.1 init

Performance

• Sampler cache lookup rewritten — no per-call enum comparisons.
• Cursor3D advance rewritten — no divisions/modulos per voxel.
• Tiny holder sets use linear scan instead of Set allocation.
• Lighting coordinate calculations now applied. (26.1+)
• BlockableEventLoop submit runs inline with no future allocations.
• GameRenderer extractCamera removed null-conditional.
• Key inputs hashCode caching simplified.
• Removed Thread.yield() from runTick for lower frame latency. (before it was just commented I dunno why, bruh)

Bug Fixes

• Fixed NativeImage region fill writing wrong color byte order.
• Fixed SoundEngine skipping camera updates before sound engine loads.
• Reverted Mth power-of-two calculation to vanilla.
• Raised ItemInHandRenderer and LightTexture(Lightmaps) mixins priority to avoid conflicts. #18

Compatibility

• Light texture and light state extraction now use cancellable injects instead of overwrites.

Removed

• Removed strict mixins: FaceBakery, SpriteContents, PalettedPermutations.
• Removed commented AccessorQuadCollection.

Performance

• Lightmap pipeline rewritten — less GPU/CPU allocations per frame.
• PoseStack uses pure mulPose rotation with cached axis transforms.
• Sound buffer library optimized.
• VertexFormat hashCode() cached.
• Lighting coordinate calculations optimized.
• TextureAtlas ported to new rendering API.
• ARGB and Mth math minor optimizations.

Bug Fixes

• Fixed item in hand rendering desync. (#15)
• Fixed mipmap generation issues.
• Fixed Mth math edge cases.

Removed

• Removed RAM-heavy optimizations (Material and Resource caching).
• Removed incompatible mixins: TextureUtil, MeshData, KeyframeAnimation.

Performance

• Chunks load smoother — faster lighting and biome data access.
• FaceSturdy block state caching.
• Bitset shapes create slightly less garbage.
• Refactored more perfomously game calculations.
• Network packets create less garbage.
• No more per-frame allocation for items held by entity.
• Resource packs now free unused mip levels after loading. Saves 10-50 MB RAM.
• Improved faces building (1.21.11+).

Bug Fixes

• Fixed a rare crash (NegativeArraySizeException) in world loading.
• Fixed lava fog appearing wrong in some camera positions.
• Fixed sound updates being skipped.
• Fixed game crash with Create Fly (#10)

New

• Added 1.21.4 and 1.21.6-1.21.8 support.

Removed

• Old low-impact and uncareful optimizations to keep the mod cleaner.

Main version: 1.21.11.

All optimizations below apply to it. On other versions (1.21, 1.21.9, 26.1, 26.2) some changes are absent due to Minecraft code differences.

Removed

• Entity culling — the mod no longer checks which entities are off-screen and skips their rendering/ticks. Removed entirely (EntityCulling, BlockEntityCulling, EntityTickCull, Frustum, Octree, SmartLeaves + utilities). Too many bugs, and the FPS gain was inconsistent.
• Config — config file, in-game config screen, ModMenu integration. The mod now works out of the box with no settings.
• OpenGL command cache — three mixins that cached viewport/scissor/polygonMode calls. Negligible gain.
• NBT throttling — thread limiting for NBT read/write + file cache. Complexity wasn't worth it.
• Platform abstraction layer — ServiceLoader and PlatformHelper removed. Simpler now.
• Chunk log spam suppression, crash report guard, translucency resort throttle — minor stuff.

Added

The mod was rewritten from scratch. Focus shifted from entity culling to hot-path acceleration and garbage elimination (less GC pressure = fewer stutters):

• Block/model rendering — faster face geometry calculations, model rotations, quaternion/matrix work. Some less allocations and less GC.
• Buffers & vertices — direct memory writes via MemoryUtil, compact color packing (2 instructions instead of 7), no more Math.addExact, cached vertex format hashes. All of these run every frame.
• Camera — fully reworked: reusable objects, unrolled loops, pre-computed near-plane vectors, cached fluid-in-camera check. Smoother movement.
• Math — bitwise operations instead of division, FMA (fused multiply-add) for distance/slerp, pre-computed rotation tables, fast rounding. Small gains that add up every frame.
• ARGB (colors) — all color operations (blending, greyscale, alpha) rewritten: no division, pre-computed lookup tables, bit shifts. Helps particles, banners, maps, etc.
• Audio — optimized buffer creation, source positioning, OGG decoding. Fewer micro-stutters when sounds load.
• Textures — unused mipmap levels get closed (frees VRAM), pre-computed filter weights for MipmapGenerator, palette caching for atlases.
• Fonts — first 8192 characters cached in a flat array instead of HashMap. Every time the game renders text — faster.
• Collections — ArrayListDeque rewritten from scratch (power-of-two capacity, bitwise masking, fixes a vanilla NegativeArraySizeException bug), ByIdMap uses Int2ObjectOpenHashMap. Faster, fewer allocations.
• Hashing — cached toString/hashCode on Identifier/ResourceLocation, Material, Transformation, BakedQuad, InputConstants, VertexFormat, TextureSetup.
• Modifier keys — Shift/Ctrl/Alt checked once per tick instead of every hasShiftDown() call.
• RenderSystem — forces GL debug flags off (debug mode hurts FPS significantly).
• EventLoop — CompletableFuture + LockSupport instead of Thread.yield().
• Shader uniforms — cached GPU buffer slices, static constants for white/zero uniforms, skip redundant writes.

Changed

• Build system — old multi-module Gradle (common/fabric/neoforge) → Stonecutter. Shared codebase with version-specific overrides.
• Package — set.starl → lomka.starl.
• Entry points — separate LomkaFabric and LomkaNeoForge.
• Versions — 1.21.11/Fabric+NeoForge (primary), plus additional variants for 1.21-1.21.1, 1.21.9-1.21.10, 26.1-26.1.2, 26.2.
