The game engine open-sourced by the company where Yunfeng (author of Skynet) works is developed with Lua, combining extremely low comprehension cost with high dynamic customizability. In terms of performance, it has designed LuaECS, which allows for performance-sensitive data to be placed within C structures, enabling the use of C/C++ to write independent Systems to handle this data, instead of the inefficient manner of Lua/C.
