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.

Hey Gabe! Absolutely loving these videos! Just finished this video and the engine runs as expected but it has relatively low fps, do you have any recommendations to where should I look to solve this problem? or in general recommendations to improve performance(other than going to c++ xd).

Hello! I am currently on episode 6 of this series. Which is unrelated to my question, but are you ever thinking about making this game engine 3D?
