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 guide covering core principles for building high-performance 3D game systems. Topics include the rendering pipeline, shader types, physics collision detection, camera control, and advanced optimization techniques like Frustum Culling and LOD. Ideal for developers needing to build visually rich and technically robust 3D environments.

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 covering advanced cryptographic hash attack techniques. Learn how to exploit inherent weaknesses such as length extension attacks (MD5, SHA-256), generating identical-prefix or chosen-prefix collisions, and analyzing side-channel timing leaks. Essential for CTF challenges and authorized penetration testing scenarios.

A comprehensive guide to exploiting PHP's loose type checking (using '==') and type juggling mechanics. This skill is crucial for bypassing security controls like authentication checks, HMAC/signature validations, and token comparisons that fail to use strictly typed comparisons (===) or timing-safe functions (hash_equals). Includes techniques for magic hash collisions and PHP version delta analysis.

This tool audits the activation metadata of coding skills used by AI agents. It grades skills (A-F) based on description clarity, simulates which skill a prompt will trigger, and identifies metadata collisions where one skill might silently overshadow another. It is essential for ensuring robust, predictable, and reliable AI agent behavior during development and CI processes.

Design responsive game cameras: 2D smooth follow with deadzone, look-ahead, and level-bounds clamping; 3D third-person orbit with collision push-in; first-person look; multi-target framing; and a shake hook. Use with any engine or camera rig system.

Master the core physics concepts in Godot 4.x, covering both 2D and 3D environments. This skill covers choosing appropriate physics bodies (RigidBody, Area, etc.), configuring complex collision layers and masks, detecting overlaps, applying forces and impulses, and utilizing raycasting for precise line-of-sight checks. Essential for building robust game mechanics.

Master the use of Godot's TileMapLayer node, the modern replacement for the deprecated TileMap. This guide teaches how to build, edit, and programmatically interact with tile-based 2D levels. Learn to configure collision layers, navigation data, custom per-tile properties, and implement complex features like autotiling and runtime cell manipulation using Godot scripting.

This guide details how to implement physics simulation using Phaser 4's lightweight Arcade Physics engine. It enables features like top-down movement, gravity control, and collision detection (colliders) for building platformers and arcade-style games. It is essential for any game requiring dynamic movement or interaction between sprites and world boundaries.

A comprehensive guide to tuning game physics parameters, including mass, gravity, drag, and continuous collision detection (CCD). It addresses common stability issues like jitter and tunneling by correctly separating the fixed-timestep simulation (physics updates) from the variable-rate rendering (visual updates) using interpolation. Essential for creating predictable and responsive game motion across various hardware.

A comprehensive guide to building 2D games using Pygame in Python. Covers the essential game loop structure (init/event/update/draw), implementing frame-rate independent movement using delta time, handling various inputs, managing objects with Sprites and Groups, and performing collision detection.
