EJOY 2D is a lightweight 2D graphics engine written in C and scripted with Lua, designed for building mobile games. It ships with a small runtime (ej2d) that executes Lua game scripts, with build support for Windows, Linux, and macOS.

Use cases

  • build a 2d mobile game with a small c engine
  • embed a 2d game engine in a c or lua project
  • render 2d sprites and animations for cross-platform games
  • script game logic in lua on top of a native graphics core
  • lightweight alternative to unity or godot for simple 2d games
  • integrate a minimal 2d renderer into an existing native app

When to choose

  • you want a tiny, embeddable C engine driven by Lua rather than a full game engine
  • you are building lightweight 2D games and want minimal dependencies (glew, freetype, glfw)
  • you are comfortable reading source code and Chinese-language API documentation

When to avoid

  • you need an actively maintained engine with recent releases and large community support
  • you expect polished tooling, an editor, or comprehensive English documentation
  • you need 3D rendering or a high-level scene system out of the box
