At the core of any gaming experience is the method the game designers use to communicate the goals and rules of the game to the player. One method of doing this, which is common across all forms of games, is through the use of a Graphical User Interface (GUI) to display and broadcast important information to the player. In this chapter, we will set up a GUI that will track the player's health, stamina, and ammo, and we will set up a counter that will display the objectives to the player. You will learn about how to set up a basic User Interface (UI) using Unreal's GUI Editor and how to use Blueprints to tie that interface to gameplay values. We will create UI elements using the Unreal Motion Graphics UI Designer (UMG).

In the process, we will cover the following topics:

• Creating simple UI meters with UMG
• Connecting UI values to player variables
• Tracking the ammo and eliminated targets
