Dealing with those events is a large part of successful Actionscript programming. In this video, Mark will teach you the basics of events and also take a look at the event object and how you can use it to write more efficient code.

Arrays are designed to allow the programmer to hold multiple pieces of data in a single structure. In this tutorial Mark, demonstrates the basics of arrays using Actionscript and Flash Builder. Mark creates two different arrays and populates them with data. Then he demonstrates several array methods that allow you to add to the array, delete from the array, and manipulate the array in several other ways.

If you are using Actionscript with Flash Professional, Flash Builder or Flex, you will find this tutorial useful.

This “How To Actionscript” series is designed for the developer who wants to learn different Actionscript techniques quickly and easily.

Flash Builder (Flex) allows you to build complex web applications using MXML and Actionscript. Due to the impressive and extensive Actionscript API, Flash Builder (Flex) applications can do almost anything. From streaming audio and video applications to games to impressive data visualizations, Flash Builder provides programmers with enormous power.

In this Actionscript Tutorial, using Flash Builder, you will create a simple, interactive application. In doing so you will see many of the major features of the Flash Builder environment.
