In section 3, we learned how to create a basic AI game using Behavior Trees, how to add game states, and how to build and publish a game.

Section 4 will teach you about advanced Blueprints concepts that will help when developing complex games. We will learn about data structures, flow control, math nodes, Blueprints tips, and gain an understanding of virtual reality development.

This chapter will explain what data structures are and how they can be used to organize data in Blueprints. We will learn about the concept of containers and how to use arrays, sets, and maps to group multiple elements, as well as other ways to organize data using enumerations, structures, and data tables. In this chapter, we will also see how to control a Blueprint's flow of execution by using various types of flow control nodes.

These are the topics of this chapter:

• Containers
• Other data structures
• Flow control nodes
