Cross-platform 2d game framework

Cocos2d-x is a high-performance C++ game development framework designed for building and deploying interactive applications across mobile, desktop, and web platforms. It functions as a cross-platform game engine that utilizes an entity-component system to manage object lifecycles, behaviors, and spatial relationships within a unified codebase. The engine is distinguished by its specialized 2D graphics rendering pipeline, which is optimized for hardware-accelerated performance when displaying sprites, particle effects, and skeletal animations. It provides developers with low-level access to gr

I'm Ivan Polyacov and this is my code library which I'm making and using in my games and other projects since early 2000x at Apus Software. It is used in many games including Spectromancer, Astral Heroes and others. Most code I wrote myself, but some minor parts were taken from other sources.…

A multi-platform Vulkan / WebGPU / OpenGL game engine that works on Desktop Java, Android and browsers.

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

Please note that Oryol is currently not actively maintained and hasn't been for a long time, my focus is currently on the Sokol headers and (from time to time) on the Chips emulator stuff.

FNA - Accuracy-focused XNA4 reimplementation for open platforms

This is a web-based 3D game engine designed for creating high-performance interactive experiences on web and mobile platforms. It functions as a real-time graphics renderer and physics engine, utilizing a component-based scene graph to organize entities and their properties for three-dimensional rendering. The engine includes a visual scene editor that allows for the design of environments through a graphical interface, which then exports these assets as executable code. Its broader capabilities cover real-time graphics rendering for 2D and 3D elements, physical world simulation for object c

KlayGE is a cross-platform open source game engine with plugin-based architecture.

Halley is a modular C++ game engine designed for building cross-platform interactive applications. Its core identity is defined by a hardware-abstraction graphics pipeline for consistent rendering across different operating systems and an entity-component-system architecture that separates game state from processing logic. The framework features a hot-reloading development environment that allows updating application logic and assets at runtime without requiring a full process restart. It also includes a multiplayer networking framework based on an asynchronous messaging system to manage real
