(This course explains the joint development of high-performance script Lua and C + + from a practical point of view. This scheme has been adopted by a large number of systems that need performance, and has become the preferred scheme for high-performance scripts, such as world of Warcraft, Bode's gate, fairy sword, Qixia biography and other games that use Lua a lot. High performance video applications are also using Lua & C + + (such as the author's company). Alphago, which recently defeated the Korean go game, is also using C + + & Lua.)
