Overview of this book

Now that Unreal Engine 4 has become one of the most cutting edge game engines in the world, developers are looking for the best ways of creating games of any genre in the engine. This book will lay out the foundation of creating a turn-based RPG in Unreal Engine 4.12. The book starts by walking you through creating a turn-based battle system that can hold commands for party members and enemies. You’ll get your hands dirty by creating NPCs such as shop owners, and important mechanics, that make up every RPG such as a currency system, inventory, dialogue, and character statistics. Although this book specifically focuses on the creation of a turn-based RPG, there are a variety of topics that can be utilized when creating many other types of genres. By the end of the book, you will be able to build upon core RPG framework elements to create your own game experience.

By selecting and clicking on the ability from the Combo Box, we need to first clear all the children from the Panel Widget using the Clear Children function, similar to what we did by clicking on the Attack button. This will prevent multiple buttons of the same target from popping up:
