Flash MX Functions

   

Flash has built-in functions that let you access certain information. For example, through the use of functions you could ascertain which version of the Macromedia Flash Player end users have on their computers. Functions that belong to an object are called methods .

For a more detailed discussion of methods, see Chapter 14, "Methods."

Each function has its own characteristics. Some functions require that you pass certain values. All of the built-in functions are outlined in Table 12.1.
