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. When to Use This skill is applicable to execute the workflow or actions described in the overview. Limitations Use this skill only when the task clearly matches the scope described above. Do not treat the output as a substitute for environment-specific validation, testing, or expert review. Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
