Overview of this book

Game development can be both a creatively fulfilling hobby and a full-time career path. It's also an exciting way to improve your C++ skills and apply them in engaging and challenging projects. Game Development Projects with Unreal Engine starts with the basic skills you'll need to get started as a game developer. The fundamentals of game design will be explained clearly and demonstrated practically with realistic exercises. You’ll then apply what you’ve learned with challenging activities. The book starts with an introduction to the Unreal Editor and key concepts such as actors, blueprints, animations, inheritance, and player input. You'll then move on to the first of three projects: building a dodgeball game. In this project, you'll explore line traces, collisions, projectiles, user interface, and sound effects, combining these concepts to showcase your new skills. You'll then move on to the second project; a side-scroller game, where you'll implement concepts including animation blending, enemy AI, spawning objects, and collectibles. The final project is an FPS game, where you will cover the key concepts behind creating a multiplayer environment. By the end of this Unreal Engine 4 game development book, you'll have the confidence and knowledge to get started on your own creative UE4 projects and bring your ideas to life.

Preface

Interfaces

There's a chance that you might already know about Interfaces, given that other programming languages, such as Java, for instance, already have them. If you do, they work pretty similarly in UE4, but if you don't, let's see how they work, taking the example of the Health Component we created.

As you've seen in the previous exercise, when the Health property of the Health Component reaches 0, that component will simply end the game. However, we don't want that to happen every time an actor's health points run out: some actors might simply be destroyed, some might notify another actor that they have run out of health points, and so on. We want each actor to be able to determine what happens to them when they run out of health points. But how can we handle this?

Ideally, we would simply call a specific function that belongs to the Owner of the Health Component, which would then choose how to handle the fact that the Owner has run out of health...
