2D game development principles. Sprites, tilemaps, physics, camera.
Principles for 2D game systems.
| Component | Purpose | |-----------|---------| | Atlas | Combine textures, reduce draw calls | | Animation | Frame sequences | | Pivot | Rotation/scale origin | | Layering | Z-order control |
| 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 |
| Type | Use | |------|-----| | Follow | Track player | | Look-ahead | Anticipate movement | | Multi-target | Two-player | | Room-based | Metroidvania |
| ❌ 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.
Notion API for creating and managing pages, databases, and blocks.
Gemini CLI for one-shot Q&A, summaries, and generation.
Remote-control tmux sessions for interactive CLIs by sending keystrokes and scraping pane output.
Capture and automate macOS UI with the Peekaboo CLI.
Use CodexBar CLI local cost usage to summarize per-model usage for Codex or Claude, including the current (most recent) model or a full model breakdown. Trigger when asked for model-level usage/cost data from codexbar, or when you need a scriptable per-model summary from codexbar cost JSON.
Interact with GitHub using the `gh` CLI. Use `gh issue`, `gh pr`, `gh run`, and `gh api` for issues, PRs, CI runs, and advanced queries.
