This chapter contains everything necessary to get started with some impressive AI. We talked about Behavior Trees, which help create decisions for your AI based on situations it encounters. Then, we talked about creating a mid-range attack for you, the player, and the AI to use. We set up the controllers and began setting up the controllers for more functions. The last thing to do before getting everything running in Behavior Tree was to set up the waypoints for the AI to patrol. Finally, we integrated everything into Behavior Tree.

You just learned how to create the basic form of game AI using the tools available within Unreal Engine 4.

We are done! We have created some fun and challenging AI. Let's now get ready for our next chapter. After learning all of this material on AI and Unreal Engine 4 and how they mix together, it is important that we spend a chapter reviewing everything that has been talked about. I will also point out the things we could have done differently. Then, we will be that much closer to a new beginning in the world of game AI!
