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

The engine uses a set of libraries for certain specific tasks.

git clone https://github.com/Mormert/jle.git --recurse-submodulesIn the command line, navigate to a game build directory, for example jle/gametemplate, and then run:
mkdir build
cd build
cmake .. -DJLE_BUILD_EDITOR=ON -DCMAKE_BUILD_TYPE=Release
cmake --build .
