## What it is
Orx is a portable, data-driven 2D/2.5D game engine written in C with C/C++ APIs. It emphasizes configuration-driven object creation, rendering, physics, audio, animation, and input across desktop, mobile, and web platforms.

## Use cases
- build a 2D game in C or C++
- create sprites and scenes from config files without recompiling
- make a cross-platform game for desktop, mobile, and HTML5
- prototype game mechanics with data-driven object templating
- add rigid body physics and joints to a 2D game
- implement multi-language support for game assets
- write custom shaders and multi-pass render pipelines

## When to choose
- you want a lightweight, permissively licensed (zlib) 2D engine in C/C++
- you prefer data-driven configuration over code-heavy scene setup
- you need one codebase targeting Windows, Linux, macOS, Android, iOS, and web
- you want fine control over rendering passes, cameras, and audio

## When to avoid
- you need a full 3D engine or high-level visual editor like Unity or Godot
- you prefer scripting languages like Lua, GDScript, or C#
- you want a large asset marketplace and community ecosystem
- your project depends on modern C++ engine abstractions or ECS frameworks

## Facets
- artifact type: framework
- maturity: stable
- function: game-engine, graphics, audio-processing, simulation
- domain: cross-platform
- platform: windows, cpp, c, wasm
- tags: 2d-engine, data-driven, 2.5d, opengl, zlib-license, physics, animation, localization, game-development, linux, macos, android, ios
