'Jet-Lagged Engine' is a work-in-progress C++/Lua game engine supporting Windows, Linux, Mac and browsers.

Cross-Platform 3D Game Engine

A simple, yet powerful custom-made C++ game engine intended for PC games.
The engine is developed alongside an unannounced game.

Build Status

Engine: jle

The engine is written in C++ 17 and currently runs OpenGL ES 3.0, OpenGL Core 3.3 or WebGL 2. It thus has the ability to build games targeting Windows, Mac and Linux, as well as modern browsers using WebAssembly via Emscripten.

The way of working in the engine is inspired by a mix of Unreal Engine and Unity, with scripting support in Lua.

jle's Issues

Build issues (might just be me)

Hey,
After watching your showcase on youtube I tried to build you engine by following the README but there does not appear to be a CMakeList file at the top level. Is this expected? Maybe I just understood your intructions wrong?

Game closes weird if console is highlighted

This is probably something to do with GLFW and termination
