Unreal Engine 4 for Beginners, as its name implies, is specifically written with the beginner in mind. It is meant for those who wish to learn how to make video games with no prior game development, game design, or game programming experience. It concentrates on the fundamentals, in order to build a rock solid foundation upon which the reader can use to confidently explore more intermediate and advanced topics. It provides a thorough examination of the basics, covering each subject in fine detail. Great care has been taken to ad vance through the subject matter in an order that best ensures that everything needed to understand one piece of information has already been covered in the information prior. It makes a great textbook for an Intro to Unreal Engine, or Unreal Engine 101 course. In addition, the book has been formatted specifically for ease of use with tablets and other mobile devices. The book concentrates heavily on four key areas: Environments - Construct beautiful environments with moving objects and sounds Inputs - Enter and explore the worlds you construct by creating a Character and specifying how it can move and how to control those movements Menus & Displays - Learn how to create the user interfaces and on-screen displays that will enhance your game and bring it to the next level Logic - Learn how to construct logic and take full control over the first three subject areas. How should objects in your world move? What should cause a certain sound to play? How does the player win the game? You decide! No need to wait for shipping! Get started learning the fundamentals of game development right now with this specially formatted ebook textbook!
