Fundamentals of ActionScript 3.0: Develop and Design

12. Conditionals

Until now, all the examples you have been working with run in a straight line. You aren’t changing courses during the execution of the code based on varying conditions. Often, you will want to do specific actions if certain conditions are met, and if they aren’t met, you want to do other actions instead. This type of action is called Boolean logic.

In this chapter, you’ll learn more about the Boolean variable type and see how you can use it to determine if certain conditions are true or false based on equality operators.
