Programming with Blueprints

This chapter presents the basic programming concepts used in Blueprints. Programming is essentially a way of writing instructions that will be understood and executed by a computer. Most programming languages are text-based, but Blueprint presents a different form of visual programming by using a node-based interface.

Some programming languages are known as scripting languages when they exist in a special environment or when they have a well-defined purpose. For example, Blueprints is the visual scripting language of Unreal Engine 4.

In this chapter, we will cover the following topics:

  • Storing values in variables
  • Defining the behavior of a Blueprint with Events and Actions
  • Creating expressions with operators
