A modern, portable game engine with an embedded editor. Completely scriptable in Lua.
Free for personal and commercial use.

Project Outline

IOLITE is in its initial development phase and is neither complete nor perfect. Things will improve rapidly but be prepared that things will most probably break at the same pace. I adhere to the release early, release often principle while incorporating community feedback. All past and future changes are documented in the changelog and roadmap.
  • Portable runtime with a minimal footprint (less than 50 MiB) that runs on Windows and Linux
  • Simplifies game creation with a focus on voxel assets from tools like MagicaVoxel or Avoyd
  • Features a powerful, beginner-friendly Lua scripting interface for rapid iteration
  • Includes an easy-to-use editor embedded in the runtime for creating original or modifying existing games
  • Utilizes modern rendering and core engine features for visually appealing, efficient games
  • Supports dynamic physics worlds with destruction and pathfinding out-of-the-box
  • A flexible license that allows you to use IOLITE for free for commercial and non-commercial projects
