• FAQ — common questions and answers
• Beginner Tutorial: Platformer Game — step-by-step guide to building your first game
• Boilerplate — ready-to-go project template with TypeScript and Vite
• Live Examples — interactive demos showcasing engine features

• The Core Engine — game loop, states, and the Application class
• Renderables — Renderable, Sprite, Text, and BitmapText
• Container — scene graph, child management, and nesting
• Adding and Managing Game Objects — world container, z-ordering, object pool, persistence
• Resources & Asset Loading — preloading images, audio, maps, and fonts

• Rendering API — full API reference with Canvas 2D comparison, gradients, dashed lines, bezier curves, and more
• Shader Effects — built-in post-processing effects on both GPU backends (glow, shine, blur, …), writing your own (GLSL and/or WGSL bodies), screen-reading effects (screen_texture / screen_uv / noise_uv), custom mesh shaders, and preloading shaders as assets
• API Documentation — auto-generated API docs

• Working in 3D — general concepts: Camera3d opt-in, conventions (Y-down + +Z forward), Mesh / OBJ rendering (retained on both GPU backends), lighting (Light3d — directional/ambient/point/spot), sprites + depth, and frame-rate-independent smoothing (math.damp). Worked example: AfterBurner showcase.
• Loading & supported 3D assets — the asset pipeline (OBJ/MTL), and what's supported vs. not across geometry, materials/textures, animation, and lighting.
• Loading glTF / GLB scenes — import a whole Blender-authored scene (node graph, meshes, camera, lights, node animation) and place each node as a Mesh.
• 3D spatial queries — Sphere, world.adapter.querySphere, raycast3d, and bulk frustum culling (Camera3d.queryVisible).
• 2.5D games (Paper Mario-style) — perspective camera for depth, gameplay on a flat Z plane.

• Adding a Physics Body — body, shapes, velocity, friction, and collision types
• Collision Shapes — Rect, Ellipse, Polygon, Line, and RoundRect
• Defining Collision Shapes in Tiled — drawing collision layers in the Tiled map editor
• Migrating to the Physics Adapter API — moving from the legacy new me.Body(this, shape) pattern to the 19.5 declarative bodyDef + body method API (all on the built-in adapter)
• Switching Physics Adapters — using @melonjs/matter-adapter, expected differences, porting checklist, recipes
• BuiltinAdapter Quirks — SAT-specific behaviors that don't carry to other engines — patterns to avoid baking into code that might switch adapters later

• Tiled Map Editor — the map editor used by melonJS
• Defining Collision Shapes in Tiled — collision layers and shape types
• melonJS Particle Studio — visual particle editor

• Using TexturePacker — create and use texture atlases
• Using SpriteIlluminator — per-pixel sprite lighting with normal maps
• Using PhysicsEditor — import complex collision shapes
• Using Bitmap Fonts — generate and render bitmap fonts
