商品描述

Are You Wondering How 2D Collision Detection In Video Games Works?

Learn how to determine shot impacts, find out which enemies are covered by lines of sight, recognize collisions of race cars or simply check if the mouse cursor floats above a button.

This Book Is Designed For Game Developers Who Want To Implement Fast And Efficient 2D Collision Detection.

The only prerequisite you need is basic knowledge in procedural programming. If you are familiar with any popular programming language like C, C++, Java, C# or Objective-C you have all you need to understand the code examples throughout the book.

What You Will Get From This Book.

The following topics get explained in detail:

  • 2D vector mathematics,
  • how to spot collisions of various 2D shapes,
  • simple yet effective body representation of game objects,
  • identifying clashing objects in motion and
  • plenty of optimization tricks.

Your Knowledge Will Be Built Up From Scratch.

The book is written for beginners, new to the topic of geometrical 2D collision detection. There are plenty of illustrations and code examples which make it easy to understand the necessary concepts and algorithms.

Use This Book As A Reference Guide.

Aside its introductional nature this book is also designed to serve as a reference guide for looking up specific collision detection functions. So advanced game programmers will derive benefit from it as well.

All The Presented Code Is Ready For Immediate Use.

The code forged throughout the book can be downloaded from the book's website and can be used right away.



商品描述(中文翻譯)

你是否想知道 2D 碰撞檢測在視頻遊戲中是如何運作的？

本書旨在幫助希望實現快速且高效的 2D 碰撞檢測的遊戲開發者。

你所需的唯一前提是具備基本的程序設計知識。如果你熟悉任何流行的程式語言，如 C, C++, Java, C# 或 Objective-C，那麼你就具備理解本書中代碼範例所需的一切。

你將從本書中獲得什麼。

以下主題將詳細解釋：


  • 2D 向量數學，

  • 如何識別各種 2D 形狀的碰撞，

  • 遊戲物件的簡單而有效的物體表示，

  • 識別運動中的碰撞物體，

  • 以及許多優化技巧。

你的知識將從零開始建立。

本書是為初學者撰寫的，適合對幾何 2D 碰撞檢測主題不熟悉的讀者。書中有大量插圖和代碼範例，使理解必要的概念和算法變得容易。
