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.

The full source code of the tutorial can be found on github: https://github.com/Quillraven/MysticWoods

Part 18 - AI State:
In this part we are going to learn how to implement the state pattern into our game and handle several states for our player like IDLE, RUN or ATTACK.
