Computer Science is the closest thing to magic we'll ever come to. I taught myself programming at a young age and am now an expert in several languages and several libraries. I have built a full engine, worked on several mobile apps and server apps. I am an expert in C++, Java, and Python. Check out my video to see a video game engine that I built from scratch. It has its own Runtime Environment, OpenGl Shaders, Actor Environment, Filesystem, Network Streaming, Physics, and Collisions System built in.
