Use when writing Java code using Universal Tween Engine (package aurelienribon.tweenengine, version 6.3.3) — Tween.to, Tween.from, Tween.set, Tween.call, Tween.mark, Timeline.createSequence, Timeline.createParallel, TweenAccessor, TweenManager, TweenCallback, easing equations (Quad, Cubic, Back, Elastic, Bounce, etc.), or waypoints/paths. Use when debugging tweens not starting, accessor not found

Use when writing libGDX Java/Kotlin code involving 2D rendering — SpriteBatch, ShapeRenderer, Texture, TextureRegion, TextureAtlas, Camera, Viewport, draw ordering, blending, or screen clearing. Use when debugging rendering artifacts, missing sprites, stretched graphics, or begin/end errors.

Use when writing libGDX Java/Kotlin code targeting the LWJGL3 desktop backend — Lwjgl3Application launcher, Lwjgl3ApplicationConfiguration, window management, fullscreen toggle, multi-window, file access (internal/local/external on desktop), desktop-specific pause/resume behavior, cursor customization, or clipboard access. Use when debugging wrong file paths, FPS/vsync configuration, or pause() no

Use when writing libGDX Java/Kotlin code involving math utilities — Vector2, Vector3, Matrix4, Quaternion, MathUtils, Interpolation, Intersector, Polygon, Circle, Rectangle, or spline curves. Use when debugging mutation bugs, wrong interpolation names, or incorrect collision detection.

Use when writing libGDX Java/Kotlin code involving Box2D physics — World creation/stepping, Body/BodyDef (Static/Kinematic/Dynamic), Fixture/FixtureDef, Shape types (PolygonShape/CircleShape/EdgeShape/ChainShape), collision filtering (categoryBits/maskBits/groupIndex), ContactListener callbacks, joints (Revolute/Distance/Prismatic/Weld/Mouse), Box2DDebugRenderer, pixels-to-meters conversion, or fi

Use when writing libGDX Java/Kotlin code that generates BitmapFont at runtime from .ttf/.otf files using gdx-freetype — FreeTypeFontGenerator, FreeTypeFontParameter, font size/color/border/shadow configuration, characters parameter for i18n, incremental glyph rendering for CJK, AssetManager integration with FreeTypeFontLoader, or density-scaled font sizes. Use when debugging missing glyphs, blurry

Use when writing libGDX Java/Kotlin code involving HTTP requests, TCP sockets, or Gdx.net. Use when debugging cross-platform networking, response threading issues, or choosing between libGDX Net and third-party HTTP libraries.

Use when writing libGDX Java/Kotlin code involving 3D physics with the Bullet wrapper — btRigidBody, btDiscreteDynamicsWorld, collision shapes, ContactListener, raycasting, MotionState, or debug drawing. Use when debugging segfaults, native memory leaks, bodies not moving, or collision detection failures in the libGDX Bullet extension.

Use when writing libGDX Java/Kotlin code involving collections (Array, ObjectMap, ObjectSet, Queue), object pooling (Pool, DefaultPool), JSON serialization (Json, JsonReader, JsonValue), I18NBundle localization, Timer scheduling, or utility classes (Align, Scaling, TimeUtils, AsyncExecutor). Use when debugging GC pressure, missing identity parameter, wrong map iteration, pooling leaks, JSON parse

Use when writing libGDX Java/Kotlin code involving AssetManager — loading assets (Texture, TextureAtlas, Sound, Music, BitmapFont, Skin, Model, TiledMap, ParticleEffect, ShaderProgram, I18NBundle), async loading screens, reference counting, screen transitions, custom loaders, or FreeType font loading via AssetManager. Use when debugging assets not loading, double-dispose crashes, missing textures

Use when writing libGDX Java/Kotlin code involving text rendering (BitmapFont, GlyphLayout, BitmapFontCache), NinePatch scalable graphics, DistanceFieldFont, or color markup language. Use when debugging wrong text position, blurry scaled fonts, text measurement, or NinePatch stretching issues.
