Skill UI

A comprehensive guide covering fundamental principles for creating 2D games. It details best practices for sprite organization (atlases, animation), tilemap design, physics implementation (collision shapes, fixed timestep), camera systems (follow, look-ahead), and genre-specific patterns like platformers and top-down games. Essential for game developers building robust 2D experiences.

A comprehensive skill guide for building complex, feature-rich web games and game engines using modern web technologies like HTML5, Canvas, WebGL, and JavaScript. Covers full 2D and 3D game development workflows, including implementing the game loop, physics simulation (collision detection, Newtonian physics), handling diverse input methods (touch, gamepad), managing assets, and integrating multiplayer features via WebRTC. Ideal for creating everything from simple platformers to advanced 3D simulations.

A comprehensive playbook for designing and implementing 'feel-good' 2D platformers, such as Mario or Celeste. This skill focuses on the compositional elements: tuning jump physics using variables like coyote time, jump buffering, and variable jump height. It teaches how to achieve responsive, satisfying moment-to-moment movement for side-scrolling games.

This skill covers core principles for 2D game development, including sprite systems, atlases, tilemaps, physics engines, and camera controls. It addresses genre-specific patterns like platformers and top-down games. Suitable for frameworks like Phaser, Kaplay, Pixi, or Canvas. Also applies to guest viewports in hybrid web apps. Focuses on performance optimization, collision handling, and animation techniques to ensure clarity and smooth gameplay.

Build, debug, test, and package playable 2D games in Go using Ebitengine, covering game loops, input, rendering, audio, scenes, gameplay tests, and desktop, browser, or mobile builds.

This skill covers fundamental principles for creating 2D video games. It includes sprite management, animation techniques, tilemap design, physics implementation, and camera systems. It also addresses genre-specific patterns like platformers and top-down views, along with common anti-patterns to avoid for better performance and clarity.
