Principles for 2D game systems. -- | Component | Purpose | |-----------|---------| | Atlas | Combine textures, reduce draw calls | | Animation | Frame sequences | | Pivot | Rotation/scale origin | | Layering | Z-order control | Frame rate: 8-24 FPS typical Squash and stretch for impact Anticipation before action Follow-through after action -- | Factor | Recommendation | |--------|----------------| | Size | 16x16, 32x32, 64x64 | | Auto-tiling | Use for terrain | | Collision | Simplified shapes | | Layer | Content | |-------|---------| | Background | Non-interactive scenery | | Terrain | Walkable ground | | Props | Interactive objects | | Foreground | Parallax overlay | -- | Shape | Use Case | |-------|----------| | Box | Rectangular objects | | Circle | Balls, rounded | | Capsule | Characters | | Polygon | Complex shapes | Pixel-perfect vs physics-based Fixed timestep for consistency Layers for filtering -- | Type | Use | |------|-----| | Follow | Track player | | Look-ahead | Anticipate movement | | Multi-target | Two-player | | Room-based | Metroidvania | Short duration (50-200ms) Diminishing intensity Use sparingly -- Coyote time (leniency after edge) Jump buffering Variable jump
