Know the Important Components of ActionScripting: Variables, Expressions, and Functions

Author: Manish Shrivastava

The programming language used in Flash web design is known as ActionScript. Flash CS3 designers need to have a good understanding of this language and its components. When you know these components such as variables, expressions, and functions, you can write good Flash scripts.
Let2019s discuss data and variables first. During an execution, most of the scripts create or use or update data. Certain type of data is used in different executions. The most common type of data is variable. Variables are created by giving them a name and a value. They should be given unique names and can be accessed and used by inserting the name anywhere in the script whenever required. For a good interactive Flash site design, an effective script is a must. Therefore creating different and unique variables is required.
A Flash web designer should also have a good knowledge of expressions. These can be defined as formulas that combine variables with operators, text, numbers, or other variables and evaluate all of them to come to a single value. They can also contain functions. During scripting, they can be used in setting values of variables, in naming movie clips, and to test if conditions are being met. With expressions a Flash web designer can assign values and also manipulate them. Doing so will add more dynamics to your Flash project thereby making the site more interactive. If you want to design a Flash page, you should heavily rely on expressions without which the project will look ordinary sans interactivity.
The last important component that Flash web designers should acquire is good understanding of functions. Functions organize computer languages and also group different but related script statements. Such a grouping is required for performing a specific task. Functions are first created and then defined before they are used in scripting.

For a more detailed understanding of these components of ActionScript and their functional importance, you can search for related tutorials on the web.
