Join the Discord: https://discord.gg/4tHeAkxNg7 In this episode I go over how to generate a JAR from the library we will be using JBox2D. Then, I will show how to integrate this JAR into our build so that we can integrate the library into our engine. Once we get the library integrated, I go over the Hello Box2D tutorial, which gives us a way to begin using Box2D inside of our engine. We will create a thin wrapper around the library, that way we only expose the critical functions to the end-user.
