Unreal Engine Game Development Blueprints

By: Nicola Valcasara

Overview of this book

With the arrival of Unreal Engine 4, a new wonderful tool was born: Blueprint. This visual scripting tool allows even non-programmers to develop the logic for their games, allowing almost anyone to create entire games without the need to write a single line of code. The range of features you can access with Blueprint script is pretty extensive, making it one of the foremost choices for many game developers. Unreal Engine Game Development Blueprints helps you unleash the real power of Unreal by helping you to create engaging and spectacular games. It will explain all the aspects of developing a game, focusing on visual scripting, and giving you all the information you need to create your own games. We start with an introductory chapter to help you move fluidly inside the Blueprint user interface, recognize its different components, and understand any already written Blueprint script. Following this, you will learn how to modify generated Blueprint classes to produce a single player tic-tac-toe game and personalize it. Next, you will learn how to create simple user interfaces, and how to extend Blueprints through code. This will help you make an informed decision between choosing Blueprint or code. You will then see the real power of Unreal unleashed as you create a beautiful scene with moving, AI controlled objects, particles, and lights. Then, you will learn how to create AI using a behavior tree and a global level Blueprint, how to modify the camera, and how to shoot custom bullets. Finally, you will create a complex game using Blueprintable components complete with a menu, power-up, dangerous objects, and different weapons.

Preparing the game

Finally, we arrive at creating our first game! Open the launcher, select the latest version of the engine and start a new project. We are going to use the Puzzle template under the Blueprint section. Call it TicTacToe, leave the other settings, such as Desktop/Console, Maximum Quality and With Starter Content, as default and click Create Project:

This is a simple template showing how the engine can be used for a puzzle game. If you click on play form the toolbar, a 3 x 3 grid (exactly what we need!) will show up, and you can interact with the pieces of the grid by clicking on them; they will change color and there is a rudimental UI showing you a counter of the pieces that are touched:

Click on the PuzzleBP folder in the Content Browser. Let's see what this template offers us. You should be able to recognize some of those elements as we discussed them in the previous chapter.
