Refactoring and Physics | Coding a 2D Game Engine in Java #40

In this episode I go over how to finish integrating Box2D into our game engine, and several different odds and ends. I go over fixing the projection size of our camera to match a more realistic camera field of view, changing the pivot point of objects to the center, modifying imgui code so that we can use enums, duplicating and deleting game objects, and editing the z index.
