A lightweight 2D game engine, in C++ with embedded Lua

Features

• Free, MIT open sourced
• Use as a standalone (GLFW based) engine or as a drop in component (e.g. with SFML)

• Rigid and soft body physics (Discrete element method)
• OpenGL rendering (provided by jGL, Vulkan is a WIP)
• Perlin (marching squares) and Tile map, editable tile based worlds
• Lua console, interoperating with the ECS, physics, and rendering systems

Setup

• clone, and init the submodules (you can use submodules.sh)
• the build.sh can be used to build
