Building an RPG with Unreal 4.x

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.

Getting player instances


If you were to test this now, you would see that a value gets created in our pause menu, but the value is 0. This is not correct because our character is supposed to start with 100 HP according to the character's current stats:

The problem occurs because the Field Player that accesses the pause menu never assigns any of our character data to Character Target. We can easily set the proper character target in Blueprint, but we won't be able to assign any of the character data without exposing our added party members to Blueprint. So, we must first head into RPGGameInstance.h and allow the exposure of our current game data to a Game Data category of Blueprint in the UProperty parameters:

UPROPERTY( EditDefaultsOnly, BlueprintReadOnly, Category = "Game Data" )

Your RPGGameInstance.h file should now look like this:

#pragma once

#include "Engine/GameInstance.h"
#include "GameCharacter.h"

#include "RPGGameInstance.generated.h"
