过去的游戏缺乏情感，也很少有值得动情的对象，因为一般游戏角色只能发出机械的声音和做出固定的动作，很难让人产生情感效果。随着计算机游戏技术的提高，我们不断完善模拟的思想、行为与情感，创建更加扣人心弦的游戏，让玩家进入强烈的情感之旅。本书介绍如何创建与提炼情感工程技术。 DavidFreeman的情感工程技术包括下列内容：让玩家认同自己的角色和与NPC(非玩家角色)结合、设计动人而出入意料的游戏时刻、创建具有情感深度的NPC。情感工程技术分为32类，本书分别介绍了所有这些技术，并对每一类中的各种技术进行了演示。

欢迎阅读《游戏编程精粹2》。《游戏编程精粹2》精选了70篇讨论各种游戏编程主题的文章，读者可将其中阐述的技术直接应用到游戏中。能给读者呈现一本这样的图书，我感到自豪。这是一本必备的参考资料，是40多位经验丰富的游戏开发人员智慧和经验的结晶。

A Theory of Fun for Game Design is not your typical how-to book. It features a novel way of teaching interactive designers how to create and improve their designs to incorporate the highest degree of fun. As the book shows, designing for fun is all about making interactive products like games highly entertaining, engaging, and addictive. The book's unique approach of providing a highly visual storyboard approach combined with a narrative on the art and practice of designing for fun is sure to be a hit with game and interactive designers, At first glance A Theory of Fun for Game Design is a book that will truly inspire and challenge game designers to think in new was; however, its universal message will influence designers from all walks of life. This book captures the real essence of what drives us to seek out products and experiences that are truly fun and entertaining. The author masterfully presents his engaging theory by showing readers how many designs are lacking because they are predictable and not engaging enough. He then explains how great designers use different types of elements in new ways to make designs more fun and compelling.Anyone who is interested in design will enjoy how the book works on two levels--as a quick inspiration guide to game design, or as an informative discussion that details the insightful thinking from a great mind in the game industry.

This engaging book presents the essential mathematics needed to describe, simulate, and render a 3D world. Reflecting both academic and in-the-trenches practical experience, the authors teach you how to describe objects and their positions, orientations, and trajectories in 3D using mathematics. The text provides an introduction to mathematics for game designers, including the fundamentals of coordinate spaces, vectors, and matrices. It also covers orientation in three dimensions, calculus and dynamics, graphics, and parametric curves.
