Pixel is a 2D game library and graphics engine for the Go programming language. It provides a hardware-accelerated renderer for drawing sprites, geometric shapes, and text, utilizing an optimized system of batching and transformation matrices. The project functions as a comprehensive toolkit for two-dimensional interactive applications, combining a graphics engine with a 2D vector math library for affine transformations and coordinate space projections. It includes a dedicated input manager that tracks keyboard presses and mouse movements using a polling-based system rather than asynchronous

Flame is a 2D game engine for Flutter and Dart. It provides a component-based game framework for managing entities and their lifecycles through a hierarchical architecture, alongside a dedicated system for game asset management and input handling. The engine distinguishes itself through a specialized integration layer for external physics engines to handle rigid body dynamics and collision detection. It also features a high-performance task model that uses isolates to offload heavy computations and prevent main thread blocking. The framework covers a broad range of capabilities including vis

Ebiten is a cross-platform 2D game engine and framework for the Go programming language. It provides a hardware-accelerated 2D renderer and a multi-input handling library to develop two-dimensional games with a single codebase. The engine is designed for broad deployment, allowing applications to be compiled and run across desktops, mobile devices, web browsers, and gaming consoles. It distinguishes itself by integrating custom shader programming for specialized visual effects and providing haptic feedback control for mobile devices and gamepads. The framework covers core game development ca

Nano is a distributed application framework designed for building systems using an actor-based messaging model. It functions as a distributed actor framework that decouples components through asynchronous messaging to maintain state isolation across a server cluster. The system acts as a cluster message dispatcher and session-aware request router, tracking client state to route incoming messages to the specific agent holding the session data. It utilizes a distributed agent registry to coordinate the dispatching of messages between multiple application instances acting as agents. The framewo

Piccolo is a mini game engine designed for building small-scale games with cross-platform support. It compiles and runs on Windows, macOS, and Linux from a unified codebase, and includes an editor integration for live editing and debugging. The engine uses a component-based entity system with data-oriented design, storing component data in contiguous arrays for cache-friendly iteration. It features a fixed timestep game loop that decouples simulation updates from rendering frame rate, and provides a physics debug overlay that renders visual shapes from simulation data synchronized with the ed

Coffee-Physics is a lightweight physics engine designed for two-dimensional particle simulation within web environments. It provides a framework for managing the movement and physical interactions of individual objects across a coordinate system, utilizing a collection of mathematical functions to calculate trajectories and collision responses. The library employs Verlet-based integration to maintain stability by tracking coordinate history, avoiding the need for explicit velocity or acceleration variables. It enforces deterministic behavior through fixed-step time stepping, which ensures con
