Lesson 9. Automating Scripts with Loops

Lesson 9. Automating Scripts with Loops

We all have to perform repetitive tasks. Whether complicated or simple, a repetitive task requires performing at least one step in a process repeatedly. For example, if you were sending out 100 wedding invitations, repetitive tasks in that process could include folding papers, stuffing envelopes, sealing envelopes, and affixing stamps—you'd do each task 100 times. In ActionScript, performing a set of repeated steps (actions) multiple times is called looping. ActionScript lets you loop through a set of actions as many times as needed, which means that instead of writing an action (or set of actions) several times, you can write it once and loop through it any number of times. In this lesson, you'll learn how to use the three loop types that ActionScript offers.

The drop-down list as well as the two-by-two grid of pictures in this application will be created dynamically by using loops.
