This is a tutorial series about game development using Kotlin, LibGDX with LibKTX extensions.
We are developing a small 2D adventure RPG using different technologies like Box2D, GdxAI, Entity Component System or Tiled.

Part 08 - Box2D:
In this part we are going to learn how to add a physic engine (Box2D) to our game. We will create a physic world, bodies and fixtures and we will align them with our images to render them correctly.
