Chapter 1, Exploring the Blueprint Editor, covers the Blueprint Editor and all the panels that are integrated into it. We will explore the Components tab, the My Blueprint tab, the Details tab, and the Viewport and Event Graph tabs. Then, we will go through what components are and how to add them to a Blueprint.
Chapter 2, Programming with Blueprints, explains programming concepts that are used in Blueprints. We will learn about how to use variables, operators, events, actions, macros, and functions.
Chapter 3, Object-Oriented Programming and the Gameplay Framework, teaches OOP concepts and explores the Gameplay Framework.
Chapter 4, Understanding Blueprint Communication, explores different types of Blueprint Communication, which allows one Blueprint to access the information of another Blueprint.
Chapter 5, Object Interaction with Blueprints, covers how to bring new objects to a level to help build the world in which the game will be set. We will move on to manipulating materials on objects, first through the object editor, and then by triggering during runtime via Blueprints.
Chapter 6, Enhancing Player Abilities, teaches you how to use Blueprints to generate new objects during gameplay, and how to link actions in Blueprints to player control inputs. You'll also learn about how to create Blueprints that allow objects to react to collisions with our generated projectiles.
Chapter 7, Creating Screen UI Elements, demonstrates setting up a graphical user interface (GUI) that will track the player's health, stamina, ammo, and current objective. Here, you will learn how to set up a basic user interface using Unreal's GUI Editor and how to use Blueprints to link the interface to the gameplay values.
Chapter 8, Creating Constraints and Gameplay Objectives, covers how to constrain the player's abilities, define the gameplay objectives for a level, and track those objectives. We'll walk through setting up collectible ammo packs that will refill the ammo of the player's gun, as well as utilizing the level Blueprint to define a win condition for our game.
Chapter 9, Building Smart Enemies with Artificial Intelligence, is a crucial chapter that covers how to create an enemy zombie AI that will pursue the player around the level. We'll walk through setting up a navigation mesh on our level and see how to use Blueprints to get enemies to traverse between patrol points.
Chapter 10, Upgrading the AI Enemies, teaches us how to create a compelling experience by modifying the zombie AI to have states in order to give the zombies a little more intelligence. In this chapter, we'll set up the patrol, searching, and attack states for the zombies by using visual and auditory detection. Additionally, we'll explore how to make new enemies appear gradually as the game is playing.
Chapter 11, Game States and Applying the Finishing Touches, adds the finishing touches that are required to make our game a complete experience before we finalize our game for release. In this chapter, we'll create rounds that will make the game increasingly difficult, game saves so that the player can save their progress and return, and player death to make the game's challenge meaningful.
Chapter 12, Building and Publishing, covers how to optimize graphics settings to get our game performing and looking its best, and how to set up project information for distribution. Then, we'll learn about how to create shareable builds of the game for various platforms.
Chapter 13, Data Structures and Flow Control, explains what data structures are and how they can be used to organize data in Blueprints. We'll learn about the concept of containers and how to use arrays, sets, and maps to group multiple elements. This chapter shows other ways to organize data using enumerations, structures, and data tables. In this chapter, we'll also see how to control the flow of execution of a Blueprint by using various types of flow control nodes.
Chapter 14, Math and Trace Nodes, covers some math concepts that are required for 3D games. We will learn the difference between world and local coordinates and how to use them when working with components. This chapter shows us how to use vectors to represent the position, direction, velocity, and distance. The concept of traces is explained and various types of traces are presented. We'll also see how to use traces to test collisions in the game.
Chapter 15, Blueprints Tips, contains several tips to increase the quality of Blueprints. We will learn about how to use various editor shortcuts that speed up our work. This chapter demonstrates some Blueprint best practices that will help you decide where and what types of implementation should be undertaken. Finally, we'll learn about more useful Blueprint miscellaneous nodes.
Chapter 16, Introduction to VR Development, explains some VR concepts and explores the VR template. This chapter explores the functionalities of the VRPawn Blueprint of the VR template and explains how to create objects that can be grabbed by the player using motion controllers. We will learn about the Blueprint functions used to implement teleportation and how to use the interface for Blueprint communication. We will also see how the menu works in the VR template.
Chapter 17, Animation Blueprints, presents the main elements of the Unreal Engine animation system, including Skeleton, Skeletal Mesh, Animation Sequences, and Blend Spaces. It shows how to script an Animation Blueprint using the Event Graph and the Anim Graph. It explains how state machines are used in an animation and how to create new states for an animation.
Chapter 18, Creating Blueprint Libraries and Components, shows how to create Blueprint Macro and Function Libraries with common functionalities that can be used throughout the project. It explains in more detail the concept of components. We will also learn how to create Actor components with encapsulated behavior and Scene components with location-based behavior.
Chapter 19, Procedural Generation, shows several ways to generate level content automatically. You can use the construction script of a Blueprint to script procedural generation and use the Spline tool to define a path that will be used as a reference to position the instances. Also, you can create an Editor Utility Blueprint to manipulate assets and actors in edit mode.
Chapter 20, Creating a Product Configurator Using the Variant Manager, explains how to create a product configurator, which is a type of application used in industry to attract consumers to a specific product. You will learn how to use the Variant Manager panel and variant sets to define a product configurator. The Product Configurator template is an excellent resource for studying various Blueprint concepts in practice. We will analyze the BP_Configurator Blueprint, which dynamically creates the user interface using UMG widget Blueprints with the variant sets.
Appendix, Quiz answers, contains the answers to all the quiz questions, chapter-wise.
