What this skill does
2D Game Development Principles for 2D game systems. --- 1. Sprite Systems Sprite Organization Component Purpose ----------- --------- Atlas Combine textures, reduce draw calls Animation Frame sequences Pivot Rotation/scale origin Layering Z-order control Animation Principles Frame rate: 8-24 FPS typical Squash and stretch for impact Anticipation before action Follow-through after action --- 2. Tilemap Design Tile Considerations Factor Recommendation -------- ---------------- Size 16x16, 32x32, 64x64 Auto-tiling Use for terrain Collision Simplified shapes Layers Layer Content ------- --------- Background Non-interactive scenery Terrain Walkable ground Props Interactive objects Foreground Parallax overlay --- 3. 2D Physics Collision Shapes Shape Use Case ------- ---------- Box Rectangular objects Circle Balls, rounded Capsule Characters Polygon Complex shapes Physics Considerations Pixel-perfect vs physics-based Fixed timestep for consistency Layers for filtering --- 4. Camera Systems Camera Types Type Use ------ ----- Follow Track player Look-ahead Anticipate movement Multi-target Two-player Room-based Metroidvania Screen Shake Short duration (50-200ms) Diminishing intensity Use sparingly --- 5. Genre Patterns Platformer Coyote time (leniency after edge) Jump buffering Variable jump height Top-down 8-directional or free movement Aim-based or auto-aim Consider rotation or not --- 6. Anti-Patterns ❌ Don't ✅ Do ---------- ------- Separate textures Use atlases Complex collision shapes Simplified collision Jittery camera Smooth following Pixel-perfect on physics Choose one approach --- Remember: 2D is about clarity. Every pixel should communicate.
