We then created a Blueprint class that inherits from that C++ class, in order to visually set up all its necessary components. We also learned briefly about Action and Axis Mappings.

In this chapter, we will be going more in-depth on these topics, as well as covering their C++ usage. We will learn about how player input works in UE4, how the engine handles input events (key presses and releases), and how we can use them to control logic in our game.

Let's start this chapter by getting to know how UE4 abstracts the keys pressed by the player to make it easier for you to be notified of those events.

In this chapter, we will be using an alternative version of the Character blueprint we created, called...
