XNA 4.0 Game Development by Example Beginner's Guide

Book Description

"

The best way to start creating your own games is simply to dive in and give it a go with this Beginner’s Guide to XNA. Full of examples, tips, and tricks for a solid grounding.

  • Dive headfirst into game creation with XNA

  • Four different styles of games comprising a puzzler, a space shooter, a multi-axis shoot 'em up, and a jump-and-run platformer

  • Games that gradually increase in complexity to cover a wide variety of game development techniques

  • Focuses entirely on developing games with the free version of XNA

  • Packed with many suggestions for expanding your finished game that will make you think critically, technically, and creatively

  • Fresh writing filled with many fun examples that introduce you to game programming concepts and implementation with XNA 4.0

  • A practical beginner's guide with a fast-paced but friendly and engaging approach towards game development

  • In Detail

    XNA Game Studio enables hobbyists and independent game developers to easily create video games. It gives you the power to bring your creations to life on Windows, the Xbox 360, the Zune, and the Windows Phone platforms. But before you give life to your creativity with XNA, you need to gain a solid understanding of some game development concepts.

    This book covers both the concepts and the implementations necessary to get you started on bringing your own creations to life with XNA. It details the creation of four games, all in different styles, from start to finish using the Microsoft XNA Framework, including a puzzler, space shooter, multi-axis shoot-'em-up, and a jump-and-run platform game. Each game introduces new concepts and techniques to build a solid foundation for your own ideas and creativity.

    Beginning with the basics of drawing images to the screen, the book then incrementally introduces sprite animation, particles, sound effects, tile-based maps, and path finding. It then explores combining XNA with Windows Forms to build an interactive map editor, and builds a platform-style game using the editor-generated maps. Finally, the book covers the considerations necessary for deploying your games to the Xbox 360 platform.

    By the end of the book, you will have a solid foundation of game development concepts and techniques as well as working sample games to extend and innovate upon. You will have the knowledge necessary to create games that you can complete without an army of fellow game developers at your back.

    A step-by-step tutorial to using Microsoft XNA by creating four different styles of video games.
