Foundation Actionscript 3.0 Animation: Making Things Move!

Description

This book is the 2nd edition of Keith Peters' best-selling ActionScript animation book, updated to ActionScript 3.0—all of the code has been updated, and some new techniques have been added to take advantage of ActionScript 3.0's new features, including the display list and new event architecture. The code can be used with the Flash IDE, Flex Builder 2, or the free Flex 2 SDK.

Flash has long been one of the most approachable, user-friendly tools for creating web-based animation. This has contributed to making it one of the most ubiquitous forms of web animation, and there are some very powerful animation scripting capabilities at your disposal—if you are still relying on key frames and tweens for the bulk of your Flash animation, you are missing out on some very exciting stuff!

This book will teach you how to use Flash ActionScript to move the objects in your movie, rather than letting Flash's tween engine do it for you. The benefit of this is smaller, more realistic, more dynamic, interactive movies that almost literally seem to come alive on your screen.

Although the text covers many advanced math and physics concepts, making for very realistic motion, there's no need to worry even if you are a relative newcomer to programming and the last math class you took was in high school (and even if you barely remember that!) The book starts with the all the basics you need to get started: principles of animation, and the basics of ActionScript, trigonometry and Flash rendering methods. It works its way slowly up from using code to move a single object across the screen, to the creation of complex systems that really push Flash's capabilities. Once you'll get to grips with it all, you'll find yourself creating all manner of exciting animations and games!

描述

這本書是Keith Peters暢銷的ActionScript動畫書的第二版，更新至ActionScript 3.0 - 所有的程式碼都已更新，並新增了一些新技術，以利用ActionScript 3.0的新功能，包括顯示列表和新的事件架構。這些程式碼可以在Flash IDE、Flex Builder 2或免費的Flex 2 SDK中使用。

Flash一直以來都是最易於接觸和使用的工具之一，用於創建基於網頁的動畫。這使得它成為最普遍的網頁動畫形式之一，並且有一些非常強大的動畫腳本功能可供使用 - 如果您仍然依賴於關鍵幀和Tween來進行大部分的Flash動畫，那麼您將錯過一些非常令人興奮的東西！

本書將教您如何使用Flash ActionScript來移動電影中的物件，而不是讓Flash的Tween引擎為您完成。這樣做的好處是可以創建更小、更逼真、更動態、更互動的電影，幾乎可以在屏幕上活躍起來。

儘管本書涵蓋了許多高級數學和物理概念，以實現非常逼真的運動，但即使您是相對新手，對編程和您上次上高中數學課的記憶已經模糊（甚至幾乎忘記了！），也不必擔心。本書從您開始所需的所有基礎知識開始：動畫原理、ActionScript的基礎知識、三角函數和Flash渲染方法。它從使用代碼將單個物件移動到屏幕上開始，逐漸建立起真正推動Flash功能的複雜系統。一旦您掌握了這些，您將發現自己可以創建各種令人興奮的動畫和遊戲！
