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 Android — AndroidApplication launcher, AndroidApplicationConfiguration, AndroidManifest.xml setup, Android lifecycle mapping to libGDX, OpenGL context loss on pause, file access (internal/local/external with permissions), Android input (back button, accelerometer, on-screen keyboard), screen density, safe insets/notch, or GL thread posting. Use when debugging black textures after resume, Activity recreation on rotation, or missing file permissions.
Use when writing a libGDX ApplicationListener or ApplicationAdapter, structuring a game's main class, or debugging lifecycle issues like missing disposal, initialization crashes, or incorrect pause/resume behavior. Use when asking where to put initialization code, how to get delta time, or which types need dispose().
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 after Android resume, or loading screen patterns.
Use when writing libGDX Java/Kotlin code involving audio (Sound, Music, Gdx.audio). Use when debugging audio not playing, audio format issues, or platform-specific audio behavior in libGDX.
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.
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 fixed timestep patterns. Use when debugging tunneling, bodies not colliding, crashes in contact callbacks, or sluggish physics movement.
Use when writing libGDX Java/Kotlin code involving 2D lighting with box2dlights — RayHandler, PointLight, ConeLight, DirectionalLight, ChainLight, ambient light, shadow rendering, soft shadows, light filtering, or attaching lights to Box2D bodies. Use when debugging lights not rendering, wrong light positions, lights not casting shadows, or performance issues with many lights.
