Well, you will be given the basic knowledge required to transform simple ideas into simple programs mixing graphics and interactive components. You are a bit lost when it comes to writing your own program from scratch, even the simplest one.
#FLASH ACTIONSCRIPT 3.0 BOOK FOR FLASH AND FLEX HOW TO#
You know how to draw a rectangle on the screen by slightly adapting the code provided, but that's about it. This assumes that you have a very basic understanding of the general format and syntax of an AS3 program and know how to compile it. Because each one explores a simple technique in isolation, they can be used as reference to Beginner and Intermediate coders. In this case, simply rapidly browse through, have a look at the demo examples. Because of this, it can be perceived as a bit dumb and slow-paced for persons who have already done some coding. This assumes absolutely no prior experience with programming whatsoever. Whatever your level, make sure that you read the instructions on How to compile an AS3 program and that you are successful at compiling the first example given on that page. A typical example of such a component would be a calendar object that pops up to let you specify a date. You can then design specialized components that will be re-used across different applications. This contributes to make the code easier to maintain and easier to re-use. This means that you have the possibility to split your code into specialized classes rather than write a single program of 3,000 lines of code. To define that counter variable in AS3, you will type something like If you want to use a counter and keep track of the counter progress in a variable, the type of data to be held in this variable will be of integer type (non negative numbers). This means that whenever you use a variable, you must provide information about the type of data that this variable is expected to hold. The reason these changes were introduced is simply because the benefits of the changes introduced in version 3 far outweight any possible inconvenience to the complete newbie. This is in part because the authoring environment let you define content and basic actions without having to care about code. These changes, however, don't prevent a person who would have never programmed before to learn the language. This may make it slightly more difficult for complete beginners to jump in. Version 3 has all characteristics of any serious programming language. Version 2 was somehow a scripting language targeted at unexperienced programmers. That specification also forms the chore of the Javascript 2.0 language contributed by the Mozilla foundation (see tamarin project at ).ĪctionScript 3.0 is an object-oriented language for creating applications and media-content that can then be played back in Flash client runtimes (typically the Adobe Flash Player, more recently the AIR framework).įor those already familiar with a Flash authoring environment, it needs to be mentioned that quite important changes have been introduced in the ActionScript language between version 2 and version 3.

This specification can be viewed on the wiki of the Ecmascript Organisation. We are not experts.ĪctionScript 3.0 is based on the EcmaScript 4th edition language specification. We write these pages as (recent) learners of the language. The focus of this page is on programming concepts that are completely tool un-specific (that would work in Flash as well as Flex). For the moment, two authoring environment are covered in this wiki, Adobe Flash CS3 and Adobe Flex. This pages is for actionscript concepts that apply to any ActionScript 3.0 authoring environment and any runtime that supports ActionScript 3.0.
