In this video we add Camera2D to our game engine, and learn a bit about matrices! I don't go in depth with matrices though, so you
should watch the videos listed below.

Vectors:

Matrices:

You don't NEED to know all the math, it is just nice to know it :) You DO need to be confident with vectors though. If you take a basic physics class, you will learn about vectors!
