What problem does it solve?
This Skill distills core 2D game development principles to help teams design clearer, more maintainable 2D game systems.
Core Features & Use Cases
- Sprite Organization: Atlas, Animation, Pivot, and Layering to improve rendering efficiency and clarity.
- Tilemap Design: Tile sizes (16x16, 32x32, 64x64), auto-tiling, collision shapes, and layered contexts (Background, Terrain, Props, Foreground).
- 2D Physics: Collision shapes (Box, Circle, Capsule, Polygon); considerations for pixel-perfect vs physics-based simulations; fixed timestep and layer filtering.
- Camera Systems: Camera types (Follow, Look-ahead, Multi-target, Room-based) and guidelines for screen shake.
- Genre Patterns: Platformer (coyote time, jump buffering, variable jump height) and Top-down (8-directional or free movement).
- Anti-Patterns: Avoid separate textures, avoid overly complex collision, avoid jittery cameras, and avoid mixing pixel-perfect with physics inappropriately.
- Use Case: Plan a small 2D platformer prototype featuring sprite atlas usage, a 16x16 tilemap, capsule collisions, and a following camera.
Quick Start
Use the 2d-games skill to set up a small prototype that demonstrates a Sprite Atlas, a 16x16 tilemap, basic capsule collisions, and a follow camera.
