KrasCore

A library of Unity extensions and utils that I use regularly both at Runtime and Editor.

Overview

KrasCore is a Unity package of runtime and editor utilities used across DOTS/ECS, rendering, tooling, and general project helpers.

Main folders:

• Runtime/: gameplay/runtime code, ECS systems, data containers, extensions.
• Editor/: inspector integrations, toolbar widgets, editor tools, and asset helpers.

Important Systems

ArtificeToolkit Integration

Artifice integration is split between runtime attributes and editor drawers:

• Runtime/ArtificeToolkit/EnableIfMethodAttribute.cs: show/hide a field based on a method result.
• Runtime/ArtificeToolkit/InlineNoFoldoutAttribute.cs: render nested fields inline (no foldout).
• Editor/ArtificeToolkit/Artifice_CustomAttributeDrawer_*.cs: UI Toolkit drawers that implement the behavior.
• Editor/Tools/Artifice_EditorWindow.cs: base editor window that renders itself via ArtificeDrawer.

Note: ButtonEnableIfMethodAttribute and ScriptableObjectCreator are present but commented out (legacy/inactive).

ParallelList (PrallelList) and Parallel-to-List Mapping

Runtime/NZCore/ParallelList/ParallelList.cs provides a high-performance per-thread list container for jobs, with:

• thread/chunk writers and readers,
• single-threaded and multi-threaded copy jobs to flatten data,
• safety integration for Unity collections checks.

Runtime/Data/Collections/ParallelToListMapper.cs wraps ParallelList<T> + NativeList<T> for common "collect in parallel, consume sequentially" flows.

var mapper = new ParallelToListMapper<MyData>(128, Allocator.TempJob);
var writer = mapper.AsThreadWriter();
// write in jobs...
var handle = mapper.CopyParallelToListSingle(dependency);

RuntimeMaterial Pipeline (ECS Graphics)

Material remapping is handled by:

• RuntimeMaterial (IComponentData) storing a material reference.
• RuntimeMaterialLookup (IEnableableComponent) storing (source material, texture) lookup keys.
• RuntimeMaterialSystem cloning/caching materials, registering BatchMaterialID when needed, applying to entities, then disabling lookup to avoid reprocessing.

This is useful for per-texture runtime material instancing without rebuilding all render data manually.

Other Runtime Utilities

Rendering

• RendererUtility: sprite UV atlas/pivot helpers + RenderParams creation.
• CameraDistort: projection tweak component for stylized camera distortion.
• GlobalUnscaledShaderTimeSystem: updates global shader UnscaledTime.
• CameraSpaceUIDocumentScaler: camera-space UI Toolkit scaling and coordinate conversion.
• VisualElementMaterial: creates per-element material instances for UI Toolkit.

Data & Collections

• BlittableBool, SampledAnimationCurve, UniTimer.
• NativeDynamicPerfectHashMap<TKey, TValue> for dynamic updates + rebuilt perfect hashing.
• Extensions/Collections/*: many helpers for NativeList, hash maps/sets, unsafe containers, and ParallelList enumeration.

Core Utils

• RandomUtils: weighted random selection.
• TrajectoryUtils: projectile path sampling.
• PlayerLoopUtils: register/remove custom loop callbacks.
• ReflectionUtils, MemoryUtils, HashUtils, StringUtils, Database.

Editor Utilities

• Editor/Tools/FindMissingScriptsTool.cs: scan scenes for missing script components.
• Editor/Tools/NormalMapperWindow.cs: batch generate sprite normal maps.
• Editor/Tools/GameViewVSyncFix.cs: preserves Game view VSync state through play mode.
• Editor/MainToolbar/*: scene-group dropdown, leak detection mode selector, Anchor toolbar visibility toggle.
• Editor/Utils/*: AssetDatabaseUtils, ScopedEditorPrefs, toolbar styling helpers, serialization helpers.
• Editor/Extensions/AddressableExtensions.cs + Editor/Utils/AddressableUtils.cs: addressables helpers (compiled only with ADDRESSABLES define).

Conditional Integrations

Several features compile conditionally:

• ADDRESSABLES
• BL_CORE
• BL_QUILL
• BL_ESSENSE
